  The main controller 200 and each device (facsimile communication control circuit 236, image reading unit 238, image forming unit 240) are supplied with power from the power supply device 202 (see the dotted line in FIG. 4). In FIG. 4, the power supply line is shown by one line (dotted line), but in reality it is two to three wires.

[Power supply device 202]
As shown in FIG. 4, the input power supply line 244 drawn from the commercial power supply 242 is connected to the main switch 246. When the main switch 246 is turned on, power can be supplied to the first power supply unit 248 and the second power supply unit 250.

  The first power supply unit 248 includes a control power generation unit 248A and is connected to the power supply control circuit 252 of the main controller 200. The power supply control circuit 252 supplies power to the main controller 200 and is connected to the I / O 210. According to the control program of the main controller 200, each device (facsimile communication control circuit 236, image reading unit 238, image forming unit 240). Switching control for conducting / non-conducting the power supply line to) is performed.

  On the other hand, a first sub power switch 256 (hereinafter also referred to as “SW-1”) is interposed in the power line 254 connected to the second power unit 250. This SW-1 is preferably a relay switch that involves a mechanical operation in the contact switching operation, and the power supply control circuit 252 controls on / off.

  The second power supply unit 250 includes a 24V power supply unit 250H (LVPS2) and a 5V power supply unit 250L (LVPS1). The 24V power supply unit 250H (LVPS2) is a power supply mainly used for a motor or the like.

  The 24V power supply unit 250H (LVPS2) and the 5V power supply unit 250L (LVPS1) of the second power supply unit 250 are selectively supplied with an image reading unit power supply unit 258, an image forming unit power supply unit 260, and a facsimile communication control circuit power supply. 264 and a UI touch panel power supply unit 266.

  The image reading unit power supply unit 258 uses the 24V power supply unit 250H (LVPS2) as an input source, and the image reading unit 238 via a second sub power switch 268 (hereinafter also referred to as “SW-2”). It is connected to the.

  The image forming unit power supply unit 260 uses a 24V power supply unit 250H (LVPS2) and a 5V power supply unit 250L (LVPS1) as input sources, and a third sub power switch 270 (hereinafter sometimes referred to as “SW-3”). And connected to the image forming unit 240.

  The facsimile communication control circuit power supply unit 264 may be referred to as a fourth sub power switch 274 (hereinafter “SW-4”) with the 24V power supply unit 250H (LVPS2) and the 5V power supply unit 250L (LVPS1) as input sources. ) To the facsimile communication control circuit 236 and the image forming unit 240.

  The UI touch panel power supply unit 266 uses a 5V power supply unit 250L (LVPS1) and a 24V power supply unit 250H (LVPS2) as input sources, and a fifth sub power switch 276 (hereinafter also referred to as “SW-5”). Via the UI touch panel 216 (including the backlight unit 216BL). Note that power may be supplied from the power-saving monitoring control unit 24 to the original functions of the UI touch panel 216 (functions excluding the backlight unit 216BL).

  Similarly to the first sub power switch 256, the second sub power switch 268, the third sub power switch 270, the fourth sub power switch 274, and the fifth sub power switch 276 are the main controller 200. On / off control is performed based on the power supply selection signal from the power supply control circuit 252. Although not shown, the switches and wirings to which the 24V power supply unit 250H and the 5V power supply unit 250L are supplied are composed of two systems. In addition, the power switches 268 to 276 may be arranged not in the power supply apparatus 202 but in each device to which power is supplied.

  In the above configuration, power is supplied to select each device (facsimile communication control circuit 236, image reading unit 238, image forming unit 240) for each function, and power is not supplied to devices unnecessary for the instructed function. Minimal power is required.

(Supervisory control for state transition of image processing device)
Here, the main controller 200 of the present embodiment may partially stop its function so as to achieve the minimum necessary power consumption. Alternatively, the power supply may be stopped including most of the main controller 200. These may be collectively referred to as “sleep mode (power saving mode)” (see FIG. 5).

  The sleep mode can be shifted, for example, by starting a system timer when image processing is completed. That is, the power supply is stopped when a predetermined time elapses after the system timer is started. If there is any operation (hard key operation, etc.) before a predetermined time (for example, corresponding to step 104 in FIG. 9) elapses, the timer count to the sleep mode is naturally canceled, The system timer is started from the end of the next image processing.

  On the other hand, during the sleep mode, a power-saving monitoring control unit 24 is connected to the I / O 210 as an element that constantly receives power. The power-saving monitoring control unit 24 can be configured by, for example, an ASIC, which is called an ASIC, stores an operation program by itself and is processed by the operation program, an IC chip including a CPU, a RAM, a ROM, and the like. .

  By the way, in the monitoring during power saving, for example, a print request is received from the communication line detection unit or a FAX reception request is received from the FAX line detection unit. In the unit 24, the first sub power switch 256, the second sub power switch 268, the third sub power switch 270, the fourth sub power switch 274, and the fifth sub power supply are connected via the power supply control circuit 252. It is assumed that power is supplied by controlling the switch 276.

  In addition, a power saving control button 26 is connected to the I / O 210 of the main controller 200, and power saving can be canceled by a user operating the power saving control button 26 during power saving. The power saving control button 26 may be operated when power is supplied to the processing unit, thereby forcibly cutting off the power supply to the processing unit and setting the power saving state. Good.

  Here, in order to monitor in the sleep mode, it is preferable to supply the power saving control button 26 and each detection unit to the power saving control button 26 and each detection unit in addition to the power saving monitoring control unit 24 while the power is being saved. That is, even in the sleep mode in which the power is not supplied, there is a case where the power is not more than a predetermined power (for example, 0.5 W or less) and is supplied with the power necessary for determining whether to supply power. is there. The power supply source at this time is not limited to the commercial power source 242, but may be a storage battery, a solar battery, a charger charged when power is supplied from the commercial power source 242, or the like.

  In addition, in a specific period of the sleep mode (in the awake mode (awk) shown in FIG. 5), a minimum necessary power supply mainly including an input system such as the UI touch panel 216 and the IC card reader 217 is included (the backlight unit 216BL is installed). It is preferable to remove or reduce the illuminance than usual).

  By the way, when the user stands in front of the image processing apparatus 10 in the sleep mode and then operates the power saving control button 26 to restart the power supply, it may take time until the image processing apparatus 10 starts up. .

  Therefore, in the present embodiment, the first human sensor 28 and the second human sensor 30 are installed in the power saving monitoring control unit 24, and the user operates the power saving control button 26 in the sleep mode. Before pressing (pressing etc.), it is detected by a human sensor (first human sensor 28, second human sensor 30) and power supply is restarted at an early stage, and the user operates the power saving control button 26. So that it can be used faster than it can be used.

  As shown in FIG. 4, the first human sensor 28 and the second human sensor 30 include detection units 28A and 30A and circuit board units 28B and 30B, and the circuit board units 28B and 30B The sensitivity of the signals detected by the detection units 28A and 30A is adjusted and an output signal is generated.

  The first human sensor 28 and the second human sensor 30 are “human feeling”, but this is a proper noun according to the present embodiment, and at least a person detects (“detection”). In other words, it also includes detection of a moving body other than a person. Therefore, in the following, the detection target of the human sensor may be referred to as “person”, but in the future, a robot or the like that executes on behalf of the person is also a detection target range. On the other hand, when there is a special sensor that can be detected by identifying a person, the special sensor can be applied. Hereinafter, a moving body, a person, a user, and the like are treated as synonymous as objects to be detected by the first human sensor 28 and the second human sensor 30, and are distinguished as necessary.

(Second human sensor 30)
On the other hand, the specification of the second human sensor 30 according to the present embodiment detects the presence / absence of a moving body, shape (contour), time-series movement information, and the like around the image processing apparatus 10. For example, an image sensor (CCD image sensor or CMOS image sensor) is applicable.

  The greatest feature of the sensor using the pyroelectric effect of the pyroelectric element applied to the first human sensor 28 is, for example, consumption compared to a reflection type sensor having a light projecting part and a light receiving part. The power is small and the detection area is wide. Further, in order to detect the movement of the moving body, the presence of the person is not detected if the person is stationary within the detection region. For example, when a high-level signal is output when a person moves, the signal becomes a low-level signal when a person within the detection range stops.

  Note that “still” in the first embodiment naturally includes complete stillness such as a still image taken with a still camera or the like. For example, a person stops in front of the image processing apparatus 10 for the purpose of operation. Including that. Accordingly, a case where a predetermined range of fine movement (such as movement accompanying breathing) or movement of a limb, neck, or the like is set as a stationary category.

  However, if a person performs a stretching exercise or the like in front of the image processing apparatus 10 while waiting for processing such as image formation or image reading, the human sensor 28 may detect the presence of the person. .

  Accordingly, the sensitivity of the first human sensor 28 is not adjusted by defining the “still”, but the sensitivity is adjusted roughly and standardly, and the sensitivity of the first human sensor 28 is adjusted. You may make it depend on a characteristic. That is, when the first human sensor 28 outputs one of the binary signals (for example, a high level signal), it indicates that the person is moving, and the second first human sensor. A case where a person exists in the 28 detection regions and another one of the binary signals (for example, a low level signal) is output may be set to be stationary.

(Second human sensor 30)
On the other hand, the specification of the second human sensor 30 according to the present embodiment detects the presence / absence of a moving body, shape (contour), time-series movement information, and the like around the image processing apparatus 10. For example, an image sensor (CCD image sensor or CMOS image sensor) is applicable.

  Since the image sensor is a general sensor that is applied as a moving image capturing unit, a detailed description thereof is omitted here.

  Image sensors are mainly made of a semiconductor made of silicon single crystal, and measure the number of freely moving electrons (signal charges) generated by the photoelectric effect to recognize the amount of light received. A photodiode is mainly used as a mechanism for storing generated signal charges without escaping.

  In the case of a color image sensor, even if the difference in brightness is known only by the signal charge amount of the photodiode, the difference in color is not known. Therefore, a color filter that transmits only light of a specific color is attached to each pixel.

  For example, in an image sensor for a digital camera, the color filter has a color and pixel arrangement called a Bayer array. Red, green and blue filters, which are said to be the three primary colors of light, are used twice as much as red and blue. This is because the human eye has high sensitivity to green light (green is felt brightest even with light of the same energy), and the resolution of the captured image is increased.

  On the other hand, the image sensor (CCD camera or the like) applied as the second human sensor 30 according to the present embodiment does not have to match the sensitivity of the human eye, in other words, the second human sensor 30. When the image sensor is applied, the arrangement of the color filters may be set according to the content to be analyzed based on the output signal from the second human sensor 30.

  As an example, instead of IC card authentication, face authentication of a person approaching the apparatus is performed, and when the authentication is performed, the image processing apparatus 10 in the sleep mode is switched to the awake mode. And a filter configuration (mainly a filter configuration in which the contour of the face, eyes, nose, mouth, etc. are clearly detected).

  In the present embodiment, the output information from the second human sensor 30 is analyzed for the main purpose of face authentication. However, in recent years, the information is regularly used and possessed by each person (hanging from the neck). In addition, a filter configuration that can detect an identification card (including a clip in a chest pocket), or a filter configuration that makes it easy to read a barcode attached to the identification card may be used.

  As another example, when determining a device to be activated in accordance with the type of document held by a person approaching the image processing apparatus 10, a filter configuration may be used that makes it easy to distinguish the type of document. For example, when the format of the facsimile transmission table is recognized, a device necessary for facsimile transmission may be started, and the display form of the UI touch panel may be determined by distinguishing between black and white / color of the document.

  In the present embodiment, the first human sensor 28 and the second human sensor 30 set two regions (the first region F and the second region N in FIG. 6).

  The first region F in FIG. 6 which is a relatively distant detection region (sometimes simply referred to as “region F”) is a detection region by the first human sensor 28 and is a relatively remote mobile object. It has a function as a means to detect. Further, the second region N in FIG. 6 (which may be simply referred to as “region N”), which is a relatively close detection region, is a detection region by the second human sensor 30 and is relatively close. It has a function as a means for detecting a moving body.

  The detection area of the first human sensor 28 (see the first area F in FIG. 6) is about 2 to 5 m as a guide, although it depends on the environment where the image processing apparatus 10 is installed. On the other hand, the detection area of the second human sensor 30 (see the second area N in FIG. 6) is a range in which the UI touch panel 216 and hard keys of the image processing apparatus 10 can be operated. It is about 2m. Note that the first detection region F and the second detection region N are not limited to the above numerical values, and what is clearly shown here is that the first region F is relatively the second region N. It is a standard to show that it is wider. Accordingly, the sensitivity of the first human sensor 28 is set for a relatively wide area (first area F) according to the environment in which the image processing apparatus 10 is installed, and a relatively narrow area ( The sensitivity of the second human sensor may be set for the second region N).

  As shown in FIG. 6, the relationship between the moving object (user) and the image processing apparatus 10 is roughly divided into three forms. In the first form, a person operates the image processing apparatus 10 for the purpose of use. The form approaching to the possible position (see the trend of arrow A in FIG. 6 (A pattern)), the second form is a form in which the person approaches the operable position, although the processing device is not intended for use ( In the third form, the person does not approach the operable position of the processing apparatus, but the third form is likely to shift to the first form or the second form. It is the form (refer the trend (C pattern) of the C line arrow of FIG. 6) which is made to a certain distance.

  In the present embodiment, by distinguishing human trends into at least the A pattern to the C pattern, the state of the image processing apparatus 10, particularly the power supply state from the sleep mode is started, or the power supply state is changed to the sleep mode. Control the fall of

  By the way, in this Embodiment, the 2nd human sensitive sensor 30 is set as the structure which is not always receiving electric power supply. The second human sensor 30 starts operating when power is supplied when the moving body (user) enters the first region F of FIG. 6 managed by the first human sensor 28. When the mobile object (user) enters the second area N of FIG. 6 managed by the second human sensor 30, the start-up from the sleep mode to the standby mode is instructed.

  That is, two human sensors (the first human sensor 28 and the second human sensor 30) having different detection areas cooperate with each other to receive the minimum necessary power supply.

  On the other hand, regarding the interruption of the power supply of the second human sensor 30, the timer function provided in the power saving monitoring control unit 24 is used in addition to the moving body detection status of the first human sensor 28. It is like that. This timer function is sometimes referred to as a “sensor timer” in order to distinguish it from the system timer described above.

  The sensor timer is one of the functions of the power saving monitoring control unit 24. That is, the control system is naturally provided with an operation clock, and a timer may be generated from this clock signal, or a counter program may be generated that counts every processing every predetermined time.

  The monitoring control unit 24 according to the present embodiment includes an integrated circuit 150 (ASIC (“Application Specific Integrated Circuit”) / one type of electronic component that operates with low power. The integrated circuit 150 is activated in synchronism with the supply of power to the second human sensor operating at the highest power consumption (power supply is provided). Based on the detection result of the second human sensor 30, the transition time by the power supply state transition control means is determined.

  FIG. 7 is a block diagram functionally illustrating control for selecting a transition destination mode and a device that supplies power by the integrated circuit 150 constituting a part of the monitoring control unit 24. Each block in FIG. 7 is a functional classification of each control, and does not limit the hardware configuration.

(Stepwise power supply control of sensor)
As described above, power is supplied from the power supply control circuit 252 to the monitoring control unit 24, and the first human sensor 28, the detection information analysis unit 152, and the power supply control unit 154 supply the power. Power is supplied directly and constantly from the control circuit 252.

  Therefore, even in the sleep mode (see FIG. 5), the first human sensor 28 always sends the detection information within the detection area (the first area F shown in FIG. 6) to the detection information analysis unit 152. Output.

  The detection information analysis unit 152 analyzes whether or not the moving body has moved within the range of the first region F. When the detection of the moving body is recognized, the detection information analysis unit 152 sends a supply instruction signal to the power supply control unit 154. It has become.

  When receiving the supply instruction signal, the power supply control unit 154 supplies power to the power supply control circuit 252, the first human sensor 28, and the integrated circuit 150.

  Further, a sensor timer 156 is connected to the power supply control unit 154, and even if a predetermined time elapses after the power supply to the second human sensor 30 or the like is started, When no moving object is detected in the detection region (second region N shown in FIG. 5) by the sensor 30, the power supply from the power supply control unit 154 to the second human sensor 30 and the integrated circuit 150 is cut off. It is supposed to be.

Note that the second human sensor from the power supply control unit 154 is used even when a predetermined time has elapsed after the startup from the sleep mode based on the second human sensor 30 and the device does not operate. 30 and power supply to integrated circuit 150 are cut off (individual authentication control by integrated circuit)
As shown in FIG. 7, the second human sensor 30 is connected to the signal receiving unit 158 of the integrated circuit 150.

  When receiving a signal from the second human sensor 30, the signal receiving unit 158 sends the signal to the signal processing unit 160.

  The signal processing unit 160 is connected to the feature region pixel extraction unit 162 and the feature region part-specific reference data storage unit 164. When the signal processing unit 160 detects a moving body based on a signal from the second human sensor 30, the detection information from the second human sensor 30 is sent to the feature region pixel extracting unit 162, and the feature region portion is also transmitted. A reference data output instruction signal is sent to another reference data storage unit 164.

  In this embodiment, the reference data storage unit 164 for each characteristic region and part stores reference data for the contour of the human face, eyes, nose, and mouth, and receives the reference data output instruction signal. The reference data is sent to the feature region pixel extraction unit 162.

  In the feature region pixel extraction unit 162, the feature region (here, the contour image region, the eye image region, the nose image region, based on the reference data based on the detection information from the signal processing unit 160 by the second human sensor 30). , Mouth image area). The feature region portion is not limited to the face outline, eyes, nose and mouth described above, but may be other feature region portions such as face color, wrinkles, hair shape, etc. It is not limited to the face, such as the type of documents that are present and the ID card hanging from the neck.

  In the present embodiment, the feature region pixel extraction unit 162 includes four types (contours, eyes, nose, mouth) of feature site matching units (outlines) 166, feature site matching units (eyes) 168, and feature site matching units (nose). ) 170, a characteristic part matching unit (mouth) 172 is connected.

  A contour database 174 is connected to the feature part matching unit (contour) 166, and collation is performed with the extracted contour and the contours of a plurality of persons registered in the contour database 174 in advance.

  An eye image database 176 is connected to the feature part matching unit (eyes) 168, and the extracted eye image and the eye images of a plurality of people registered in the eye image database 176 are checked in advance.

  A nose image database 178 is connected to the feature part verification unit (nose) 170, and the extracted nose image is compared with the nose images of a plurality of people registered in the nose image database 178 in advance.

  A mouth image database 180 is connected to the feature part matching unit (mouth) 172, and the extracted mouth image is compared with mouth images of a plurality of persons registered in the mouth image database 180 in advance.

  A feature part matching unit (contour) 166, a feature part matching unit (eyes) 168, a feature part matching unit (nose) 170, and a feature part matching unit (mouth) 172 are each connected to the individual authentication unit 182 and verified. Information is sent to the individual authentication unit 182.

  The individual authentication unit 182 performs individual authentication based on the respective pieces of collation information, and specifies, for example, personal information of a user who is permitted to register in advance. This specific permission / inhibition and the personal information of the user when specified are sent to the mode determination unit 186 and the processing device selection unit 188 via the authentication result output unit 184.

  The mode determination unit 186 determines an optimal mode of the image processing apparatus 10 based on the specific availability information and the user's personal information, and outputs a startup trigger to the main controller 200 via the information output unit 190. . Based on this startup trigger, power is supplied to the main controller 200, and mode transition control based on the startup trigger is executed.

  In addition, the processing device selection unit 188 needs to use the specified user based on the job (print, copy, scan, facsimile transmission / reception, etc.) that the specified user intends to perform based on the specific permission / inhibition information and the personal information of the user. Selects a processing device, and outputs the selected information to the main controller 200 through the information output unit 190 together with the startup trigger.

  Hereinafter, the operation of the present embodiment will be described.

(Mode transition of power supply control of image processing apparatus 10 (device))
First, based on FIG. 5, a timing chart showing each mode state and an event that triggers the transition of the mode state in the image processing apparatus 10 is shown.

  If the image processing apparatus 10 is not processed, the operation state is the sleep mode, and in this embodiment, power is supplied only to the power-saving monitoring control unit 24.

  Here, when there is a startup trigger (detection of a startup trigger or operation input (key input) of the UI touch panel 216 or the like), the operation state transitions to the warm-up mode.

  Note that after the start trigger is triggered, the sleep mode may still be defined, and only the UI touch panel 216 may be activated, or only the power saving monitoring control unit 24 may be powered by the activation of the UI touch panel 216. Since the amount of power supply increases more, it may be defined as an awake mode “awk” (wake-up mode) (see in parentheses {} in the sleep mode range in the transition diagram of FIG. 5). When there is an operation input (key input) on the UI touch panel 216 or the like in this awake mode, the operation state transitions to the warm-up mode.

  The startup trigger mainly includes a signal, information, and the like based on the detection result by the second human sensor 30. Note that a power-saving canceling operation by the operator may be used as a startup trigger.

  In the warm-up mode, the image processing apparatus 10 is brought into a processable state quickly, so that the maximum power consumption in each mode is achieved. For example, by using an IH heater as a heater in the fixing unit, a halogen lamp is used. The warm-up mode time is relatively shorter than the heater used.

  When the warm-up operation in the warm-up mode is completed, the image processing apparatus 10 transitions to the standby mode.

  The standby mode is literally a “preparation is complete in preparation” mode, and the image processing apparatus 10 is ready to execute an image processing operation.

  For this reason, when there is a job execution operation as a key input, the operation state of the image processing apparatus 10 transitions to the running mode, and image processing based on the instructed job is executed.

  When the image processing is completed (when a plurality of continuous jobs are waiting, when all the continuous jobs are completed), the operation state of the image processing apparatus 10 is changed to the standby mode by the standby trigger. Note that, after image processing, timing by a system timer may be started, and after a predetermined time has elapsed, a standby trigger may be output to transition to the standby mode.

  If there is a job execution instruction during the standby mode, the mode transits to the running mode again, and when the falling trigger is detected or a predetermined time elapses, the mode transits to the sleep mode.

  The falling trigger includes a signal, information, and the like based on the detection result by the second human sensor 30. A system timer may be used in combination.

  Further, the mode state transitions in the actual operation of the image processing apparatus 10 do not all proceed in time series as shown in this timing chart. For example, the process may be stopped in the standby mode after the warm-up mode and the mode may be shifted to the sleep mode.

  Here, each device that operates by receiving the supply of power can immediately execute each process by shifting from the sleep mode in FIG. 5 to the standby mode through the awake mode and the warm-up mode.

  As described above, the image processing apparatus 10 according to the present embodiment transits between the modes, and the power supply amount is different for each mode.

  In the image processing apparatus 10 according to the present embodiment, when a predetermined condition (for example, the moving object (user) leaving information by the human sensor 30 or the output of the falling trigger due to the time-up of the system timer) is met, Transition to mode. In this sleep mode, power is supplied not only to the facsimile communication control circuit 236, the image reading unit 238, and the image forming unit 240, but also to the main controller 200 excluding the power saving monitoring control unit 24, and the UI touch panel 216. Cut off. In this case, it is preferable that the function of the power saving control button 26 connected to the main controller 200 is also stopped. For this reason, when the image processing apparatus 10 is viewed from the periphery, the state is almost the same as the state where the main power switch is turned off. That is, it is possible to confirm from the surroundings that the sleep mode is being executed reliably (realization of “visualization”).

(Power saving for human sensors)
In the present embodiment, the first human sensor 28 and the second human sensor 30 cooperate with each other to execute power supply control to the detection system. Specifically, the first human sensor 28 constantly supplies power, but the second human sensor 30 performs control to supply electric power based on the detection information of the first human sensor 28. In addition to controlling power supply to devices, it has further improved energy efficiency.

  More specifically, the devices of the image processing apparatus 10 (facsimile communication control circuit 236, image reading unit 238, image forming unit 240) are based on the first human sensor 28 and the second human sensor 30. Considering the contradictory objectives of energy saving and convenience, appropriate mode transitions (particularly, starting from the sleep mode and falling to the sleep mode) are performed. In this case, the detection system such as the first human sensor 28 and the second human sensor 30 is assumed to be constantly supplied with electric power.

  On the other hand, in the present embodiment, power is supplied to the first human sensor 28 while power is supplied to the second human sensor 30 during the sleep mode shown in FIG. The approach of the moving body (user) to the first area F shown in FIG. 6 is not monitored. In the range of the first region F, the first human sensor 28 detects the moving body (user), so that electric power is supplied to the second human sensor 30.

  Furthermore, in this embodiment, an image sensor is applied as the second human sensor 30, and the accuracy of power supply control of the device is improved by analyzing the captured image and performing face authentication of the moving object. Yes. That is, false detection of a person (non-user) who is detected as a moving object but is not a person, or who is a person but only passes through is prevented.

  Also, by analyzing the image taken by the image sensor and identifying the user based on the personal information database registered in advance, the user's personal information is specified within an allowable range, and the purpose of use of the image processing apparatus 10 is predicted. It is also possible to do.

  Hereinafter, a detection system power supply control routine based on cooperation between the first human sensor 28 and the second human sensor 30 will be described with reference to the flowchart of FIG. 8.

  FIG. 8 is a flowchart showing a monitoring control routine mainly performed by the monitoring control unit.

  In step 100, it is determined whether or not the first human sensor 28 has detected a moving body (user). If a negative determination is made, the process proceeds to step 102, where the second human sensor 30 is turned on. That is, it is determined whether or not power is supplied. If a negative determination is made in step 102, the process returns to step 100, and steps 100 and 102 are repeated until a positive determination is made in step 100 or step 102.

  If an affirmative determination is made in step 100, the routine proceeds to step 104, where the second human sensor 30 is turned on, that is, the supply of power is started, and then the routine proceeds to step 106, where the sensor timer is reset and started. Migrate to

  If the determination in step 102 is affirmative, the power has already been supplied to the second human sensor 30, and the process proceeds to step 108.

  In step 108, it is determined whether or not the second human sensor 30 has detected a moving body (user). If a negative determination is made, the process proceeds to step 110 to determine whether or not the sensor timer has timed out. Is judged. If a negative determination is made in step 110, the process returns to step 108, and steps 108 and 110 are repeated until a positive determination is made in step 108 or step 110.

  If an affirmative determination is made in step 110, the process proceeds to step 112, the sensor timer is stopped, and then the process proceeds to step 113, where the second human sensor 30 is turned off, that is, the supply of power is shut off. Returning to step 100, the above process is repeated.

  If an affirmative determination is made in step 108, the process proceeds to step 114, and image analysis processing is executed based on the detection signal from the second human sensor 30 (image sensor) (see FIG. 9).

  In the next step 115, it is determined whether the job, that is, the processing content has been recognized as a result of the image analysis.

  If an affirmative determination is made in step 115, the process proceeds to step 116, a start trigger for awake mode is output to the main controller 200 (see FIG. 4), and the process proceeds to step 118. Due to the start trigger, power is supplied to the minimum necessary part of the image processing apparatus 10 and the sleep mode is changed to the awake mode. Thereafter, the user starts up a necessary device based on the operation of the UI touch panel 216 or the like, and shifts to the running mode by inputting a job execution key or the like, and image processing can be executed.

  In step 118, it is determined whether or not the sensor timer started in step 106 has expired. If a negative determination is made in step 118, the process proceeds to step 120, where it is determined whether or not the operation of the system timer has started. If a negative determination is made, the process returns to step 118, and in step 118 or 120. Steps 118 and 120 are repeated until an affirmative determination is made.

  If an affirmative determination is made in step 118, the routine proceeds to step 122, the sensor timer is stopped, and then the routine proceeds to step 124, where the second human sensor 30 is turned off, that is, the power supply is cut off. finish. If an affirmative determination is made in step 120, it is determined that the standby mode has been entered due to the standby trigger, the process proceeds to step 121, the control subject is transferred to the main controller 200, and this routine ends.

  If the determination in step 115 is affirmative, since the processing content is recognized, the process proceeds to step 126 and a start trigger corresponding to the job content is output. That is, only the devices necessary for processing are started up and set to the standby mode.

  When the start trigger output in step 126 is completed, the process proceeds to step 128, the control subject is transferred to the main controller 200, and this routine ends.

  The above is the flow of control mainly for supplying power from a state in which the image processing apparatus 10 is in the sleep mode and no power is supplied to the second human sensor 30. Basically, the second human sensor 30 is not supplied with electric power unless a moving body (user) enters the first area F under the jurisdiction of the first human sensor 28. In addition to power saving of the device, This will further improve the energy saving effect.

  FIG. 9 is a control flowchart showing an analysis processing subroutine in step 114 of FIG.

  In step 130, image information is acquired from the second human sensor 30.

  When the image information is acquired, the process proceeds from step 130 to step 132, the reference data for each characteristic region part is read, and then the process proceeds to step 134 to extract the characteristic region image. In the present embodiment, a face outline, eyes, nose, mouth and the like are selected as the feature region image.

  In the next step 136, the feature region extracted for each part is compared with the individual feature region stored in the database, and the process proceeds to step 138 to execute the individual authentication process. By this individual authentication process, the person detected by the second human sensor 30 is specified.

  In step 140, mode determination (determination of an appropriate transition mode of the device) is performed based on the information of the person specified by the individual authentication, and then the process proceeds to step 142 to select a processing device and to step 144. Transition. In step 144, information regarding the determined mode and the selected processing device is output, and the routine ends.

  As described above, in the present embodiment, a pyroelectric sensor is used as the first human sensor 28, an image sensor such as a CCD camera is used as the second human sensor 30, and the first human sensor 28 is used. Regardless of the mode type, power is always supplied, but the second human sensor 30 suppresses power consumption by interrupting the supply of power in the sleep mode. In addition, when the first human sensor 28 detects a moving body, power is supplied to the second human sensor 30, and individual authentication is performed based on imaging information obtained by the second human sensor 30. The information about the user was obtained with higher accuracy than the detection accuracy of the first human sensor 28, and the necessary minimum power consumption was realized without impairing convenience.

(Modification)
"Infrared array sensor"
In this embodiment, a pyroelectric sensor is applied as the first human sensor 28. However, as the first human sensor 28, a plurality of elements for detecting a heat source are arranged two-dimensionally vertically and horizontally. The two-dimensional array type heat source detection means (infrared array sensor 28IR (see FIG. 7)) may be applied. Further, the infrared array sensor 28IR may be applied as an intermediate position between the first human sensor 28 and the second human sensor 30 according to the present embodiment. The power consumption is about 0.015 Wdc.

  “Intermediate positioning” is a classification based on power consumption. Since power consumption is larger than pyroelectric sensors and smaller than CCD cameras, first, if a moving object is detected by constantly monitoring with pyroelectric sensors. Power may be supplied to the infrared array sensor 28IR, and then power may be supplied to the CCD camera.

  Hereinafter, the configuration of the infrared array sensor 28IR will be described in detail with reference to FIGS. The block diagram of the control function system shown in FIG. 10 (B) does not limit the hardware configuration, but blocks the signal processing output from the infrared array sensor 28IR by function.

  As shown in FIG. 10A, the infrared array sensor 28IR includes a detection unit 28A and a circuit board unit 28B (hereinafter, also referred to as “analysis unit 28B”) in which the detection unit 28A is attached in the center. I have.

  28 A of detection parts have an element which detects a heat source. The element for detecting the heat source is a thermopile element, and this thermopile element is 8 (vertical) × 8 (horizontal) (= 64 elements) in a two-dimensional matrix. As a commercial item, there exists a brand name: Grid-Eye (grid eye) "trademark" / made by Panasonic Electric Works.

  The specifications of the commercially available infrared array sensor include a thermopile element (array shape) as the sensor unit 28A, a condensing silicon lens, a MEMS (Micro Electro Mechanical Systems) sensor as the analysis unit 28B, an IC, and the like. The module is a built-in mounting module, can detect a region with a viewing angle of 60 degrees and a maximum of 5 to 10 m ahead, and can be applied as the first human sensor 28 of the present embodiment.

  Note that MEMS refers to a device in which mechanical element parts, sensors, actuators, and electronic circuits are integrated on a single silicon substrate, glass substrate, organic material, or the like.

  The infrared array sensor 28IR detects a temperature change of a person or a heat source in a specific space in a non-contact manner by analyzing a temperature distribution based on a detection signal corresponding to a thermal image detected by the detection unit 28A (thermopile element). The direction of movement of a person or the like can be detected.

  As shown in FIG. 10B, the electrical signal from the detection unit 28A is received by the electrical signal reception unit 50 of the analysis unit 28B, and the signals detected by the respective thermopile elements are stored in the pixel-by-pixel data storage unit 52. It has become so. Here, it is assumed that all the functions of the analysis unit 28B are provided in the circuit board unit 28B shown in FIG. 4, but the analysis unit 28B does not have to have all the functions, and some of them are shown in FIG. The function of the monitoring control unit 24 shown in FIG.

  A data extraction unit 54 is connected to the pixel-by-pixel data storage unit 52. For example, data is extracted in units of pixels and sent to the temperature level determination unit 56. An electrical signal-temperature level characteristic table storage unit 58 is connected to the temperature level determination unit 56, and the temperature level based on the received electrical signal (in this embodiment, four levels shown in FIG. 11C). Decide either.

  The determined temperature level information is sent to the detection result determination unit 60.

  A temperature distribution / state collation table storage unit 62 is connected to the detection result determination unit 60. In the detection result determination unit 60, based on the temperature distribution-state collation table stored in the temperature distribution-state collation table storage unit 62, for example, as a basic pattern, as shown in FIG. When a person is present in the detection area 28A, the state (in this case, “the person exists” and “the person moves”) is determined from the detection result (temperature distribution) (see FIG. 11B).

"Reflective sensor"
In addition, a reflective sensor may be applied as a sensor that is positioned between the first human sensor 28 and the second human sensor 30 according to the present embodiment.

  The reflective sensor can detect the presence / absence (presence / absence) of a moving body, and includes a light projecting unit and a light receiving unit. Note that the light projecting unit and the light receiving unit may be separated.

  The greatest feature of this reflection type sensor is to reliably detect the presence or absence of a moving body by blocking / not blocking light entering the light receiving section. In addition, since the amount of light incident on the light receiving unit is limited by the amount of light projected from the light projecting unit, a relatively short distance is the detection region.

"Gesture sensor"
Furthermore, a gesture sensor is applied as the first human sensor 28 according to the present embodiment or as an intermediate sensor that is positioned between the first human sensor 28 and the second human sensor 30. Also good.

  The gesture sensor uses, for example, a microwave Doppler sensor to detect an operation as a difference in Doppler, and performs a Fourier transform on the sensor detection signal to detect a gesture. The power consumption is about 0.25 Wdc.

  FIG. 12 shows a pyroelectric sensor applied as the first human sensor 28 of the present embodiment, an image sensor (CCD, CMOS) applied as the second human sensor 30, and an intermediate position thereof. It is the characteristic view which showed the correlation of the specification (power consumption and detection distance) with respect to a possible infrared array sensor, a reflective sensor, and a gesture sensor. The sensor shown in FIG. 12 can be selectively applied as the first human sensor 28 and the second human sensor 30, but the second human sensor 30 is an individual such as an image sensor. A sensor that can be authenticated is preferable. In other words, the image sensor is not limited to a CCD or a CMOS as long as it is a sensor capable of individual authentication, and may be, for example, an infrared array sensor with high-density pixels.

(Application example of power supply control device)
In the above embodiment, the power supply control device is applied as a control device that changes the mode of the image processing device 10, in particular, from the sleep mode to the standby mode. However, most of the power is cut off as needed. The present invention can also be applied to power supply control of a device that executes load power supply in stages (including a case where power is supplied to a higher sensor by a lower sensor).

"vending machine"
Vending machines are installed on the streets, in stores, on the premises of stations, etc. so that drinking water is represented. Furthermore, not only drinking water but also snacks, books, newspapers, bouquets and toys are sold. Tickets are also a type of vending machine for stations.

  Since it is unclear when such a vending machine is operated by the purchaser, in many cases, the vending machine always stands by in a state where all power is supplied with an emphasis on convenience. However, there are vending machines that are frequently used, and there are also vending machines that are used sporadically, so when considering energy savings, power should be supplied when people approach, It is difficult to determine whether or not the purchaser is on a busy street.

  Therefore, for example, when a predetermined time elapses when there is no purchase, power supply to the main function of the operation unit of the vending machine is cut off, and power is supplied to the first human sensor 28. deep. In this case, the first human sensor 28 is preferably a reflective sensor having a relatively narrow detection range in order to distinguish a person who passes frequently and a person facing the vending machine. Alternatively, the detection range may be adjusted by arranging a partition plate such as an aperture on the detection surface of the pyroelectric sensor.

  When the first human sensor 30 determines that there is a possibility of using the vending machine by the first human sensor 28, electric power is supplied and individual authentication is performed.

  For example, it is possible to create a database for nationality determination, determine nationality by the above-mentioned individual authentication, and selectively display the native language of many countries such as Japanese, English, French, etc. It becomes. Further, it is possible to provide a service in which the display screen and the operation surface are directed to the normal line depending on the height (eye height).

  Further, as shown in FIG. 13A, the first human sensor 28 and the second human sensor 30 are attached to the vending machine 300, and the high position discharge port 302 and the low position discharge port 304 are provided. It is also possible to provide a service in which the height (eye height) of the purchasers 306A and 306B is determined by the individual authentication of the second human sensor 30 and the outlet is selected. As shown in FIG. 13B, it is determined that the purchaser 306A is short, and the purchased product is discharged from the low-position outlet 304, and as shown in FIG. Is determined to be high, and the purchased product is discharged from the high position discharge port 302.

"Auto-lock system"
FIG. 14 is a front view of a common entrance where the auto-lock system is a condominium or the like. The entrance is provided with a front door 310, which is opened and closed by a driving force of a driving means 312 such as a motor. The driving means 312 is controlled by the controller 314 of the auto-lock system.

  The controller 314 is connected to an intercom signal line 316 provided in each room and an operation panel 318. The resident can open the entrance door 310 by operating the identification number for each room from the operation panel 318. Further, the visitor can open the entrance door 310 by operating the intercom by operating the room number of the visited site.

  In such a known auto-lock system, electric power is always supplied, and convenience is established, but energy saving is sacrificed. For this reason, the first human sensor 28 and the second human sensor 30 are installed in such an automatic lock system, and the power supply other than the first human sensor 28 is cut off by a timer or the like. .

  Thereafter, monitoring by the first human sensor 28 is continued, and power is supplied to the second human sensor 30 when a person is detected.

  At this time, if personal information of the resident (including images of the face outline, eyes, nose, mouth, and the like) is registered in the database, and the person is authenticated by individual authentication, the operation panel 318 is obtained. Even if power is not supplied to the door, the entrance door 310 is opened.

  On the other hand, if the user is not a resident, power is supplied to the operation panel 318 so that an input operation such as a room number can be performed.

  Furthermore, by applying the second human sensor 30 of the present embodiment, an image of the wanted person is registered in the database in cooperation with the nearest police, etc. It is also possible to take a crime prevention measure such as alarming when it matches the arranger (or matches with a predetermined probability). In addition to the operation of the warning sound and the warning lamp, or in place of the operation, the alarm includes not supplying power to the operation panel 318, automatically reporting to the police, a light company, or the like.

  In the above, the embodiment in which the first human sensor 28 and the second human sensor 30 are provided with the image processing apparatus 10 as a main component has been described, and the vending machine and the auto lock system have been described as application examples. It can be applied to all devices that supply power by supplying power in stages from the lowest power consumption and finally predicting the subsequent operation by individual authentication. Both energy savings are possible.

  It should be noted that devices that cut off most of the power and execute the load power supply step by step (including the case where the lower sensor supplies power to the upper sensor) are the office, factory, It is installed in warehouses, stores, hotels, stations, airfields, parking lots, roadsides, walkways, markets, tourist facilities, event venues, schools, libraries, government offices, other public facilities, private facilities, etc. By providing the power supply control device mainly including the first human sensor 28 and the second human sensor 30 according to the present embodiment, it is possible to achieve both convenience and energy saving.

  Further, the first human sensor 28 and the second human sensor 30 are not necessarily built in the apparatus. For example, the first human sensor 28 and the second human sensor 30 or a part or all of the control system device may be a device different from the monitoring device, and may be connected by, for example, wired or wireless. .
