Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera for photographing, and more particularly, to a camera capable of displaying a charging state of a strobe and an operating state of the camera.

[0002]

2. Description of the Related Art In recent years, as cameras have become more sophisticated,
Various modes are displayed on a liquid crystal display means provided outside the camera to make the design easy for the user to operate.

In addition, the functions of a film counter and a self-timer, which were previously mechanically configured, tend to be concentrated on the mode display liquid crystal unit.

Further, as the function of imprinting a message on a photograph has evolved, a technology for displaying a message on a dot matrix type LCD has been disclosed, for example, in Japanese Patent Laid-Open No. 9-90492.
No., etc.

[0005] On the other hand, with the spread of game devices, mobile phones, personal computers, and the like, the consciousness of users for machines has been changed, and personal use devices are not merely means but interactive or interactive devices. It has been increasingly positioned as a playful tool for information exchange. Historically, cameras older than these devices have been relegated to the recent user orientation and have repeatedly followed the notion of providing the minimum required display.

[0006]

However, in many cases, such a display with the minimum required simply emphasizes the aggregation of functions, and does not take into account the enjoyment and clarity of the visual user. Did not. In addition, it is difficult for a user to grasp this information in the case of information whose state changes, such as flash charging.

On the other hand, for some devices such as watches, a design called a see-through design, in which a part of or the entire exterior is transparent to make the movement inside the device easy to understand, is known. This not only has the effect of allowing the user to recognize the movement of the machine and confirming the operation with confidence, but also has the idea of feeling the flow of time in the movement of the machine and feeling a kind of virtual communication.

On the other hand, in the case of a camera, there is a concern that stray light may enter the film or the light receiving element, so that the exterior is concealed in black, and various electronic and mechanical controls are taking place inside the camera during photographing. It is difficult to inform the user.

Therefore, the present invention seeks to reduce the cost of the camera by consolidating its functions, while taking into account the priority and importance of the required display according to the state of the camera, and making the camera easy for the user to understand. Fun to have,
The purpose is to provide a camera that pursues a human interface.

[0010]

Means for Solving the Problems That is, the first invention is:
At a predetermined time interval, in a camera having detecting means for detecting a temporal change in the state of a camera element and display means for displaying the state change, the display means may detect the temporal change in the state. It is characterized in that it is dimensionally displayed in real time.

According to a second aspect of the present invention, in a standby state in which a user is required to wait for a predetermined time or more during operation of the camera, information on the standby time and an operation in the camera which cannot be visually recognized by the user in the standby state And a display device for displaying
It is characterized by having.

A third aspect of the present invention provides a monitor for monitoring a state of electric energy required for operating the camera, a unit for operating the monitor at predetermined time intervals, and an output of the monitor at predetermined time intervals. Display means for displaying based on the relationship between the number of times of monitoring by the monitoring means and the result of the monitoring.

In the camera according to the first aspect of the present invention, the detecting means detects a temporal change in the state of the camera element at predetermined time intervals, and the state change is displayed on the display means. Then, on the display means, the temporal state change is displayed two-dimensionally in real time.

In the camera according to the second aspect of the present invention, in a standby state in which the user is required to wait for a predetermined time or more during operation of the camera, information on the standby time is displayed on the display device, and The operation in the camera that cannot be visually recognized by the user is displayed.

Further, in the camera according to the third aspect of the present invention, the monitor means monitors the state of electric energy required when the camera operates. This monitoring means is activated at predetermined time intervals. Then, the output of the monitoring means at every predetermined time is displayed on the display means based on the relationship between the number of times of monitoring by the monitoring means and the result of the monitoring.

In the camera of the present invention, the movement inside the camera can be visually recognized by the user by devising the display on the LCD provided on the exterior of the camera.

[0017]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1A is a block diagram showing a configuration of an internal electronic circuit of the camera according to the first embodiment of the present invention.

In FIG. 1A, an arithmetic control circuit (CP
U) 1 controls the sequence of the entire camera,
It is composed of a one-chip microcomputer and the like. The CPU 1 has a switching unit 1a and an A / D conversion circuit 1b inside.
A dot matrix LCD (hereinafter simply referred to as LCD) 2 and a switch 3 including a release button and the like are connected to the outside. The LCD 2 is controlled in a matrix manner by common lines and segment lines, and is controlled by a small number of ports.

The CPU 1 also includes a distance measuring (AF) unit 4, a photometric (AE) unit 5, a focusing unit 6 for focusing a photographic lens (not shown), a battery check circuit 7, and a shutter 8 , A strobe 9 and a magnetic reading unit 10 for reading data recorded on a magnetic recording unit of a film (not shown).
Photographing is performed under the control of U1.

Power is supplied from the power supply 11 to each of the above-described circuits. The state of the power supply 11 is monitored by the battery check circuit 7, and its output is input to the A / D conversion circuit 1b built in the CPU 1 so that the state of the battery can be determined.

FIG. 1B shows the basic concept of the present invention, and is a flowchart for explaining the display operation of the camera according to the first embodiment.

First, the CPU 1 is controlled to execute step S
At 1, the current state of the camera is determined. here,
The display is switched between digital display (A) and analog display (B) depending on the state of the camera.

If it is determined that the display is an analog display,
Proceeding to step S2, the monitoring time interval is shortened. Then, the process proceeds to step S3, and a display is made in an analog display form as shown in FIG. On the other hand, if it is determined in step S1 that the display is a digital display, the process proceeds to step S4, where the digital display as shown in FIG.

Thereafter, the process proceeds to step S1.

For example, before photographing, when the state of the power supply 11 is checked by the battery check circuit 7, as shown in FIG. 1D, only an image display (digital display) that the battery has sufficient energy is made. Is enough. However, during or after shooting, battery consumption and recovery become severe, so that the display in the form of a meter-type analog display as shown in FIG. Make an announcement. This makes the display appeal as a more expressive human interface.

As described above, by switching the display on the LCD 2 between the digital display and the analog display, the display can be performed.
Since the user can intuitively grasp the function of the electric circuit inside the camera, he / she can confirm the normality of the operation with peace of mind, and can enjoy the camera other than the moment of shooting.

Next, a second embodiment of the present invention will be described.

FIGS. 2A and 2B show the appearance of a camera according to a second embodiment of the present invention. FIG. 2A is a view from the back of the camera, and FIG. 2B is a front view.

A photographing lens 16 is attached to the front of the camera body 15 at a substantially central portion.
Above 6, an object lens 17 of the finder, a light projecting lens 18 for AF, a light receiving lens 19, and a strobe light emitting section 20 are arranged.

A release switch 23 and a zoom switch 24 are provided on the upper surface of the camera body 15 to determine the photographing timing and the photographing magnification of the zoom lens by operating the user.

An eyepiece 25 of a finder is provided on the back of the camera body 15 for the user to observe the subject at the time of photographing, and is opened and closed on the right side for loading a film (not shown) on the right side. An opening / closing lever 26 for opening / closing a back cover 27 is disposed.

A large LCD panel 30 for displaying photographing information of the camera is disposed substantially at the center of the back cover 27. A self-timer switch 31 for setting a self-timer mode is provided around the LCD panel 30.
A mode switch 32 for switching modes such as strobe light emission and prohibition, a display switch 33 for switching information displayed on the LCD panel 30, a rewind switch 34 for forcibly rewinding the film, and a date to be imprinted on the film (date at the time of shooting). ) Switches 35 and 36 for switching display and the like are arranged.

The LCD panel 30 described here is assumed to be of a dot matrix type, and is shown in FIG.
As shown in the figure, normally, the display 38 of the number of frames of the film being shot or the display 4 of the mode setting of the self-timer or the strobe light.
In addition to 0 and 41, imprint display 39 of the date function described above is performed. Depending on the date mode, Figure 4
As shown in (a), the time may be displayed instead of the date.

By the way, when the camera is used, there is a timing at which shooting cannot be performed continuously. In such a state, photographing cannot be performed. Therefore, it is preferable for the user to display information indicating why photographing cannot be performed, rather than displaying photographing-related information.

It is more significant if it is possible to determine how long the waiting time is required or that the camera has not failed. These indications
Because I can understand the mechanism of the camera, I can satisfy my intellectual curiosity.

For example, at the timing of charging the strobe energy, the CPU 1 may control the LCD display by controlling according to the flowchart shown in FIG. That is, the normal display and the charging display are switched depending on whether or not the battery is in the charging state.

In the flowchart of FIG. 5, first, in step S11, it is determined whether or not to charge the strobe. If charging is not performed, step S
The process proceeds to step S12, and a normal display as shown in FIG. On the other hand, when charging is performed, the process proceeds to step S13 to perform a process of displaying a charge.

FIG. 4 shows the display during flash charging.
As shown in (b), the time change of the charging voltage may be displayed in a graph. Further, in order to clarify that the flash charging is performed, as shown in FIG.
The lightning mark 42 may be additionally displayed on the screen of the D panel.

Further, switching between the normal display and the charging voltage change display can be performed according to the operation of the changeover switch 33 according to the user's preference.

When the display is made in step S12 or S13, the process proceeds to step S14, where the photographing process of the camera is performed, and thereafter, the process proceeds to step S11.

FIG. 6 is a diagram showing an example of a circuit configuration of a strobe.

In FIG. 6, oscillation circuits 46 and 47 include:
Under the control of the CPU 1, the transistors 48 and 49 cause a current to flow through the coil 51 or 52 of the transformer on the primary side of the transformer connected in series with the battery 50.
Therefore, an amplified current according to the winding ratio flows through the secondary coil 53, and charges are stored in the capacitor (main capacitor) 55 via the diode 54.

When a voltage as high as 300 V is charged in this way, a trigger voltage by a trigger circuit 57 is applied to the Xe tube 56 of the strobe. As a result, discharge light emission occurs, and flash photography can be performed.

The winding ratio of the above transformer is
Switching is performed depending on which of 8 and 49 is controlled. In the case of control of the transistor 48, the winding ratio is large, and it is efficient to greatly amplify a small voltage. On the other hand, transistor 4
In the case of 9, the turn ratio is small, and it is efficient to amplify a small voltage to a not so large voltage. Therefore, if the transistor 49 is controlled at the beginning of charging and the transistor 48 is controlled during the latter half of charging, high-speed charging becomes possible.

FIG. 7 is a flowchart for explaining the charging operation on the LCD when the above-described winding ratio switching method is employed. In this example, an example is shown in which dot display is performed each time the voltage changes.

When the flash charging process is started, a timer (not shown) in the CPU 1 is first started in step S21. Next, in step S22, the charging voltage of the strobe is checked.

Then, in step S23, the charging voltage is compared with a predetermined switching voltage. If the switching voltage has not yet been reached, the process proceeds to step S24, where the turns ratio of the transformer is reduced, and the process proceeds to step S25.
Is displayed according to the voltage. Then, step S2
When the timer is counted at 8, the process proceeds to step S22, and the subsequent processing is repeated.

On the other hand, if it is determined in step S23 that the charging voltage has become equal to or higher than the predetermined switching voltage, the process proceeds to step S23.
Then, the process proceeds to step S26, where the turns ratio of the transformer is increased, and a display corresponding to the voltage is made in step S27. Thereafter, when the timer is counted in step S28, the process proceeds to step S22, and the subsequent processing is repeated.

Further, as shown in FIG. 8, the voltage may be monitored at predetermined time intervals, and the dot display position may be controlled at each time interval.

FIG. 8A shows an example where the charging time is short, and FIG. 8B shows an example where the charging time is late such as at the end of the battery. Such a display clearly shows that the charge curve changes when the battery is new and when it has deteriorated.

Next, a third embodiment of the present invention will be described.

In general, various controls in the camera tend to be slowed down when the battery deteriorates, and the user also wants to know the timing of battery replacement, so that the state of battery voltage and battery energy consumption is displayed. That is also important.
Therefore, it is also effective to display not the voltage of the main capacitor of the strobe but the battery voltage or the current consumption.

Since the battery voltage may recover after rapid consumption, it changes as shown in FIG. 9A during flash charging. By displaying such a change state on the LCD panel, the user can easily determine whether the battery has deteriorated or whether the battery can be used again after waiting.

The display can be switched in response to the manual operation of the display switch 33 described above.

Also, if the current consumption is displayed in the form of a meter as shown in FIGS. 9B and 9C, the user can easily understand what kind of operation the battery is liable to deteriorate, and energy saving is made. You can also shoot. This is an idea applying a car tachometer. By applying the present embodiment using a dot matrix LCD, a camera that requires less battery replacement can be provided.

When the battery cannot be used completely, a message to replace the battery (BATNG) may be displayed as shown in FIG. 9D. Alternatively, FIG.
As shown in (g), a scroll display indicating that the battery needs to be replaced may be displayed.

By the way, for a user who feels that such information is complicated or confused, it is sufficient to prepare a mode in which these displays can be erased, or prepare a version in which such displays do not appear.

FIG. 10 is a diagram showing an example of a circuit configuration for performing the above-described current monitoring.

In FIG. 10, this current monitor circuit
From the camera battery 60 to the wiring resistance (R ₁) 61, (R_Two)
62, the input terminal of the operational amplifier 64 is connected.
You. The output terminal of the operational amplifier 64 is connected between the input terminal and
Wiring resistance (R_Three) 63 is connected and CPU 1 is connected.
Has been continued.

The DC / DC converter 65 is connected between the wiring resistance (R ₁ ) 61 and the CPU 1. Further, the CPU 1 includes an EEPROM 66 and an LCD 2.
Is connected.

In such a configuration, the camera battery 6
It is assumed that the CPU 1 and other camera control circuits are driven from 0 through the DC / DC converter 65. The voltage drop (R ₁ × I) caused by the wiring impedance R ₁ from the battery 60 to the DC / DC converter 65
_BAT ) is detected by the operational amplifier 64. Also,
This I _BAT is the current consumption of the camera.

The output V _{OUT of the} operational amplifier 64 has the wiring resistances R ₂ and R ₃ of the following formulas (1) and (2) based on the above R ₁ and the following formula (3). V _BAT = R _{1 ·} I _BAT + V ₁ = R ₂ · I ₁ + V ₁ (1) Therefore, I ₁ = (R ₁ / R ₂ ) · I _BAT (2) V _OUT = V ₁ −R ₃ · I ₁ = V ₁ − (R ₁ · R ₃ / R ₂ ) · I _BAT (3) Therefore, if the CPU 1 detects V ₁ and V _OUT using the built-in A / D conversion circuit 1b, I _BAT can be detected from the calculation of the expression 4). I _BAT = (R ₂ / R ₁ · R ₃ ) (V ₁ −V _OUT ) (4) If the LCD 2 is controlled according to this, the current consumption can be displayed.

FIG. 11 is a flow chart for explaining the display operation of the monitor current in the third embodiment.

If it is determined in step S31 that the photographing path has not been taken and the image forming apparatus is on standby, the process proceeds to step S32 and C
A timer (not shown) in PU1 is counted. After a predetermined time has elapsed in step S33, the wiring resistance value and the like of the camera are read from the EEPROM 66 in the following step S34.

Next, in step S35, the value of V ₁ is the A / D converted by the A / D converter circuit 1b in the CPU 1. Similarly, in step S36, the value of V _OUT is A / D
Is converted.

Then, in step S37, the value of I _BAT is obtained from the difference between V ₁ and V _OUT . Next, in step S38, according to the obtained _IBAT value, the LCD
2 is switched. Then, the above step S32
Move to

On the other hand, if the process is not to wait in step S31, the process shifts to step S39 to determine whether or not photographing is performed. Here, when the photographing is not performed, the process proceeds to step S31, and when the photographing is performed, the process proceeds to step S40 to perform the photographing process.

The wiring resistances R ₁ , R ₂ , R _3, etc.
Since it varies depending on the variation of parts,
If the value of the camera is written in advance in 6, an accurate display can be made by referring to this value each time it is displayed.

Next, a fourth embodiment of the present invention will be described.

The fourth embodiment is a countermeasure against the rewinding time of the film at the time of changing the film, which is always a problem in the silver halide camera.

The rewinding time is also a long waiting time for the user to take a picture or to change the film, and depending on the situation, causes a great deal of pain to the user. Simply rewinding the film could not tell if rewinding was being performed correctly, and sometimes it was frustrating to predict how long rewinding would end.

Therefore, in the fourth embodiment, FIG.
By the LCD display as shown in FIGS. 3 (a) and (b),
The situation is communicated to the user to let them know what is happening inside the camera.

FIG. 12 is a view for explaining film winding of the camera according to the fourth embodiment.

Referring to FIG. 12A, a film 72 is wound around a film cartridge 70 and a spool 71. The film 72 is connected to a CPU (not shown).
The rewinding is performed in a direction indicated by an arrow in FIG.

A photoreflector 75 for detecting a perforation 74 formed on the film 72 is arranged near the wound film 72, as shown in FIG. The photoreflector 75 is configured by a pair of a light emitting element and a light receiving element, and detects the perforation 75 by monitoring a change in a situation in which the film 72 reflects light projected from the light emitting element by the light receiving element. It is supposed to.

When the rewind motor 73 is driven, the film 72 is rewound, and the perforations 74 formed on the film 72 are removed by the photo reflector 75.
Is detected by Thus, the CPU can perform feedback control of the rewinding of the film 72 and also can perform display control.

FIG. 13 shows a display (mark) indicating such a film rewinding state. 13 (a) and 13 (b), the user is notified that the film 72 in FIG. 13 (b) is shorter and the rewinding is completed in about half the waiting time. .

In FIG. 13, the right-pointing △ mark indicates that two are displayed and one is displayed repeatedly, so that the film rewinding proceeds smoothly. Can be displayed.

In such a configuration, the display control operation as shown in FIGS. 13A and 13B will be described with reference to the flowchart of FIG.

First, in step S51, it is monitored whether or not the film is in a rewinding state. If it is not rewinding, the process proceeds to step S62, where the timer indicating the rewinding time is reset, and the normal display as shown in FIG. 4A is performed.

On the other hand, if the film is being rewound, the flow shifts to step S52, as shown in FIG. 13A, where two right-pointing △ marks indicating rewind and a display pattern A indicating a film mark are displayed. Is displayed.

Next, in step S53, it is determined whether or not a rewind rotation signal by driving the rewind motor 73 or a perforation signal by the photo reflector 75 is detected. Here, every time the rewind motor rotation signal is detected or the perforation signal is detected, in step S54, the timer counts the elapsed rewind time and counts down the film frame by the CPU.

In the conventional camera, only the number of frames is counted down in the normal display shown in FIG. 4A. However, when the battery is deteriorated, the countdown is slow, and the user can instantaneously determine what the frame number is. It cannot be determined what is happening. Therefore, in the fourth embodiment, a visual analog display that is easier to convey the situation is performed.

In synchronism with the countdown in step S54, the right triangle mark on the LCD changes from step S55 to step S5.
At 7, the display of FIGS. 13A and 13B is sequentially repeated, and the length of the film of the mark displayed on the LCD is reduced in step S <b> 58 according to the rewinding state of the film. The elapsed rewind time is displayed on the LCD. Then, control goes to the step S53.

In step S53, when the rewind motor rotation signal or the perforation signal is no longer detected, the rewinding of the film is terminated.
That is, first, in step S59, it is determined whether a predetermined time has elapsed. Here, if the fixed time has not elapsed, the process proceeds to step S53. If the predetermined time has elapsed, the process proceeds to step S60, and the rewind motor is stopped. Then, step S
At 61, an indication of rewind end (RWEND) is displayed as shown in FIG. 15A, so that the user can determine that the film can be taken out.

Further, in this film rewinding, a graph display as shown in FIG. 15B may be made in the same manner as in the above-described flash charging. This is shown in FIG.
Only the relationship between the elapsed time shown in (a) and (b) and the film length is displayed in a graph, and this can be realized if the CPU calculates the coordinates of the lighting dots and sequentially lights the dots. It is. In this case, when the vertical axis becomes 0, it means that the rewinding is completed.

As described above, according to the fourth embodiment, a camera that does not cause the user to feel uneasy or dissatisfied with the operation of the camera during the standby time during film rewinding. Can be provided.

According to the above embodiment of the present invention,
The following configuration can be obtained.

That is, (1) In a camera having detection means for detecting a temporal change in the state of a camera element at predetermined time intervals, and display means for displaying the above-mentioned state change, the display means ,

[0096]

As described above, according to the present invention, while the dot matrix type liquid crystal is more effectively used and the cost of the camera is reduced by consolidating the functions, it is required according to the state of the camera. Considering the display priority and importance,
It is possible to provide a camera that is easy for the user to understand and that is fun to have a camera and that pursues a human interface.
