Description

  The present invention relates to an imaging apparatus, and more particularly, to an imaging apparatus using dynamically reconfigurable hardware.

  Many digital still cameras (DSCs) employ a single-plate color image sensor (for example, a CCD image sensor or a CMOS image sensor). In the single-plate color image sensor, each pixel has only single color information. For this reason, in a DSC that employs a single-plate color image sensor, a required complement process (synchronization process (also referred to as demosaicing process)) is performed on image data (RAW data) obtained from the image sensor at the time of shooting. The visible image data (for example, Y / C data including luminance data Y and color difference data Cr and Cb) is generated. In many DSCs, retouch processing such as brightness correction and color tone correction is performed simultaneously with the complement processing, and the completed image data is stored in a general-purpose image format such as JPEG or TIFF.

  For this reason, a DSC that employs a single-plate color image sensor usually has hardware such as a circuit that generates Y / C data from RAW data, a circuit that performs required retouch processing, a circuit that performs compression processing, etc. ASIC (Application Specific Integrated Circuit) is mounted.

  However, hardware such as an ASIC has a problem that it is difficult to change the function after manufacturing because the logic function is built into the chip in hardware at the time of manufacturing.

  On the other hand, in Patent Document 1, a dynamically reconfigurable hardware is mounted on a DSC so that a function for performing image processing and a function for performing arithmetic processing of various parameters can be switched with a single hardware. Has been proposed. In this DSC, calculation processing of various parameters is performed during an invalid period in which image processing is not performed.

  In Patent Document 2, a reconfigurable hardware is mounted on a DSC having a still image shooting function and a moving image shooting function, and a function of compressing still image data with a single hardware and a moving image data It has been proposed that the function for performing the compression process can be switched.

Japanese Patent Application Laid-Open No. 2004-228561 proposes that a reconfigurable hardware is mounted on a DSC, and that the function of the hardware is switched to perform image data compression processing step by step.

  However, since the technology of Patent Document 1 simply switches between an image processing function and a parameter calculation processing function, when compressing image data obtained by shooting and recording it in an image recording means, compression is performed. There is a drawback that additional hardware is required. Also, if compression processing is performed with reconfigurable hardware, the processing is time-division processing, so there is a disadvantage that the photographing interval becomes long.

  In addition, the techniques disclosed in Patent Documents 2 and 3 have a drawback that separate image processing hardware is required because the contents of compression processing are simply switched by reconfigurable hardware.

  The present invention has been made in view of such circumstances, and provides a photographing apparatus that can be configured with a small circuit, can be photographed comfortably, and can safely store image data obtained by photographing. For the purpose.

The CPU 14 controls the drive of the iris motor 46i via the iris motor driver 48i, thereby controlling the amount of light incident on the image sensor 18 by opening the aperture 16i.

  The image sensor 18 is a CCD image sensor having a predetermined color filter array (for example, Bayer), and is disposed behind the photographing optical system 16 so as to be orthogonal to the photographing optical axis.

  In the present embodiment, a CCD image sensor is used as the image sensor 18, but an image sensor having another configuration such as a CMOS image sensor can also be used as the image sensor 18. Further, the pixel array is not limited to a square array, and a honeycomb array can also be used.

  The image sensor 18 operates in accordance with the drive signal applied from the timing generator 50, converts the signal charge accumulated in each pixel (light receiving element) into a voltage signal, and outputs it as an image signal dot-sequentially.

  The image sensor 18 is provided with a shutter drain via a shutter gate in order to realize an electronic shutter function. When the shutter gate is driven via the timing generator 50, the signal charge accumulated in each pixel of the image sensor 18 is swept out to the shutter drain. Therefore, by controlling the driving of the shutter gate, the signal charge accumulation time accumulated in each pixel can be controlled, and the shutter speed can be controlled.

  The image input controller 26 captures an image signal for one frame output from the AFE 20 under the control of the CPU 14. The image signal for one frame captured from the AFE 20 by the image input controller 26 is the RAW data of the captured image. The taken RAW data is stored in a predetermined area of the work memory 40.

  The image processing performed by the DRP 28 will be described in detail later.

  Under the control of the CPU 14, the display controller 30 reads the image data generated by the simple development process or the development process from the work memory 40, converts it into the display format of the display device 32, and outputs it. For example, the display device 32 is composed of a color LCD.

  The AE / AF / AWB detection unit 34 detects the focus evaluation value (so-called contrast information), the brightness of the subject, and the light source type using the RAW data of the captured image captured via the image input controller 26.

  The information on the focus evaluation value is used for AF (Auto Focus) control, and the CPU 14 searches the position of the focus lens 14f where the focus evaluation value is maximized, and focuses the main subject (so-called contrast AF).

  Information on the brightness of the subject is used for AE (Auto Exposure) control, and the CPU 14 calculates an EV value based on the information on the brightness of the subject and determines exposure (aperture value, shutter speed).

  Information on the light source type is used for AWB (Auto White Balance) control, and the CPU 14 sets a WB parameter for white balance based on the information on the light source type.

  The external communication unit 36 transmits / receives data to / from an external device connected via a predetermined communication interface under the control of the CPU 14. In DSC 10 of the present embodiment, USB is adopted as a communication interface. Therefore, any device having a USB interface can be connected via a USB cable and can transmit and receive data to and from each other.

  In this example, the USB interface is used to communicate with the external device. However, the means for communicating with the external device is not limited to this, and other communication means may be used for communication. . Further, the connection form is not limited to a wired one, and may be a form of connection by wireless. Therefore, for example, in addition to this, a configuration may be adopted in which communication with an external device is performed by a wired LAN, a wireless LAN, Bluetooth, infrared communication, or the like.

<Operation>
Next, the operation of the DSC 10 of the present embodiment configured as described above will be described.

  As described above, the DSC 10 of the present embodiment is equipped with the DRP 28, and the realized function (circuit) is switched according to the situation.

  That is, in the state of waiting for a shooting instruction before the main shooting, information on a circuit that performs simple development processing of RAW data for display is downloaded to the DRP 28, and the DRP 28 functions as a simple development processing circuit. Thereby, the video captured by the image sensor 18 can be displayed through on the display device 32.

  When the main shooting is instructed from the waiting state of the shooting instruction, information on a circuit for performing correction processing (scratch correction, shading correction, etc.) unique to the image sensor is downloaded to the DRP 28, and the DRP 28 functions as a correction processing circuit. . When the main shooting is instructed, the RAW data subjected to the correction process is recorded in the image recording memory 44. By recording in the RAW data state in this way, it is possible to save development processing time and shorten the photographing interval.

  On the other hand, since RAW data cannot be displayed on the display device 32 as it is, it needs to be developed. In the DSC 10 of the present embodiment, when it is confirmed that the power of the camera is turned off and power is supplied from the AC adapter 56, development processing of recorded RAW data is performed. That is, when it is confirmed that the power of the DSC 10 is turned off and the power is supplied from the AC adapter 56, information of a circuit for developing RAW data for recording is downloaded to the DRP 28, and the DRP 28 is developed. Functions as a circuit. As a result, the RAW data can be converted into visible data (YC data in this example) whose image quality has been adjusted.

  In the DSC 10 of the present embodiment, when the development processing is completed, information on a circuit that compresses the further developed image data (YC data) is downloaded to the DRP 28, and the DRP 28 functions as a development processing circuit. As a result, an image can be stored without pressing the capacity of the image recording memory 44.

  In the simple development processing for display, development processing is performed at a level at which at least the photographing area can be identified. On the other hand, in the recording development process, a development process accompanied by a process for improving the image quality is performed.

  For example, in the simple development process for display, a process of synchronizing RAW data in which each pixel has only one color information of R, G, B so that each pixel has color information of R, G, B (Complementary processing) is performed.

  On the other hand, in the recording development process, the synchronized data is converted into image data (YC data) composed of luminance data (Y data) and color difference data (Cr, Cb data), and image data after YC conversion (YC data) YC data) is subjected to retouching processing such as contrast enhancement processing, edge enhancement processing, and noise reduction.

  The development process can be realized by a single circuit, but it is preferable to divide a circuit that realizes each process and process in time series.

  2 to 3 are flowcharts showing the flow of processing operations of the DSC 10 of the present embodiment.

  First, the CPU 14 determines whether the mode of the DSC 10 is the shooting mode based on the input from the operation unit 12 (step S10).

  When the CPU 14 determines that the mode of the DSC 14 is set to the photographing mode, the CPU 14 reads out information on a circuit for simple development processing for display from the program memory 42, downloads it to the DRP 28, and allows the DRP 28 to function as a simple development processing circuit. Realize (Step S11). Thereby, the through display on the display device 32 becomes possible. The CPU 14 sequentially captures image signals from the image sensor 18, causes the DRP 28 to perform simple development processing, adds the generated image data (synchronized image data) to the display controller 30, and displays a through image on the display device 32. (Step S12).

  The photographer looks at the through-displayed image on the display device 32, confirms the composition, etc., and presses the release button to instruct the actual photographing. The CPU 14 determines whether or not the main photographing has been instructed based on the signal input from the operation unit 12 (step S13).

  If it is determined that the main shooting has been instructed, the CPU 14 executes a main shooting process, and captures image data (RAW data) for recording from the image sensor 18 (step S14). The image data for recording is temporarily stored in the work memory 40.

  When the CPU 14 captures the image data for recording, the CPU 14 reads out information on a circuit (correction circuit) for performing flaw correction and shading correction specific to the image sensor from the program memory 42, downloads the information to the DRP 28, and functions the correction processing circuit in the DRP 28 Is realized (step S15). Then, the RAW data obtained by the actual photographing is added to the DRP 28, and correction processing unique to the image sensor is performed (step S16).

  The CPU 14 records, in the image recording memory 44, RAW data that has been subjected to correction processing unique to the image sensor such as flaw correction (step S17).

  The imaging of one image is completed in the series of steps described above. Thereafter, the CPU 14 returns to step S11, downloads the information of the circuit for simple development processing for display to the DRP 28, and causes the DRP 28 to realize the function of the simple development processing circuit (step S11). Then, a through image is displayed on the display device 32 (step S12).

  If it is determined in step S13 that an instruction for actual shooting has not been given, the CPU 14 determines whether or not the shooting mode has been changed based on an input from the operation unit 12 (step S18). If it is determined that the shooting mode has not been shifted, the CPU 14 returns to step S13 again to determine whether an instruction for actual shooting has been issued (step S13).

  On the other hand, if it is determined that the shooting mode has been changed, as shown in FIG. 3, it is determined based on a signal from the operation unit 12 whether or not an instruction to turn off the power has been issued (step S20).

  If it is determined that the power-off is not instructed, the CPU 14 determines that the transition to another mode is instructed, and starts processing in the instructed mode (for example, the reproduction mode) (step S27). ).

  On the other hand, when determining that the power is turned off, the CPU 14 determines whether or not the AC adapter is connected based on the information from the power management unit 38 (step S21). If it is determined that the AC adapter is not connected, the CPU 14 ends the process.

  On the other hand, when determining that the AC adapter is connected, the CPU 14 accesses the image recording memory 44 and determines whether or not undeveloped RAW data exists (step S22). If it is determined that there is no undeveloped RAW data, the CPU 14 ends the process.

  On the other hand, if it is determined that undeveloped RAW data exists, the CPU 14 executes a development process for recording (step S23).

  FIG. 4 is a flowchart showing the procedure of recording development processing.

  First, the CPU 14 reads undeveloped RAW data from the image recording memory 44 and develops it in the work memory 40 (step S30).

  Next, the CPU 14 reads out information on a circuit that performs RAW data synchronization processing from the program memory 42, downloads the information to the DRP 28, and causes the DRP 28 to realize the function of the correction processing circuit (step S31). Then, the undeveloped RAW data developed in the work memory is added to the DRP 28, and the DRP 28 is caused to perform a synchronization process. The processed image data is stored in the work memory 40 again.

  Next, the CPU 14 reads out information on a circuit that performs YC conversion processing on the image data after synchronization from the program memory 42, downloads the information to the DRP 28, and causes the DRP 28 to realize the function of the YC conversion processing circuit (step S32). Then, in addition to the synchronized DRP 28 stored in the work memory, the image data is converted into image data (YC data) composed of luminance data (Y data) and color difference data (Cr, Cb data). The image data (YC data) after YC conversion is stored in the work memory 40 again.

  Next, the CPU 14 reads out the information of the circuit that performs noise reduction processing on the image data after YC conversion from the program memory 42, downloads it to the DRP 28, and causes the DRP 28 to realize the function of the noise reduction processing circuit (step S33). Then, the YC-converted image data stored in the work memory is added to the DRP 28 to perform noise reduction processing. The image data (YC data) after the noise reduction process is stored in the work memory 40 again.

  Next, the CPU 14 reads out the information of the circuit that performs the contrast enhancement processing on the image data after the noise reduction processing from the program memory 42, downloads it to the DRP 28, and causes the DRP 28 to realize the function of the contrast enhancement processing circuit (step S34). Then, the image data after the noise reduction process stored in the work memory is added to the DRP 28, and the contrast enhancement process is performed. The image data (YC data) after the contrast enhancement process is stored in the work memory 40 again.

  Next, the CPU 14 reads out the information of the circuit that performs the edge enhancement processing on the image data after the contrast enhancement processing from the program memory 42, downloads it to the DRP 28, and causes the DRP 28 to realize the function of the edge enhancement processing circuit (step S35). Then, the image data after the contrast enhancement processing stored in the work memory is added to the DRP 28, and the edge enhancement processing is performed. The image data (YC data) after the edge enhancement processing is stored in the work memory 40 again.

  The development process for recording is completed in the series of steps described above, and recording image data (YC data) is generated.

  Thereafter, as shown in FIG. 3, the CPU 14 performs a process of compressing the generated image data for recording (here, a process of compressing the YC data by JPEG). That is, the information of the circuit for compressing the image data is read from the program memory 42, downloaded to the DRP 28, and the DRP 28 realizes the function of the compression processing circuit (step S24). Then, the image data for recording stored in the work memory is added to the DRP 28 and compressed. The generated compressed image data is stored in the work memory 40 again.

  The CPU 14 adds predetermined attached information to the generated compressed image data, generates an image file (Exif file here) in a predetermined format, and stores it in the image recording memory according to a predetermined recording format (DCF here). Recording is performed (step S25).

  Thereafter, the CPU 14 accesses the image recording memory 44 and determines whether or not undeveloped RAW data exists (step S26). If it is determined that there is no undeveloped RAW data, the process ends.

  On the other hand, if it is determined that there is undeveloped RAW data, the process returns to step S23, and recording development processing is executed on the undeveloped RAW data.

  As described above, in the DSC 10 of the present embodiment, the entire circuit scale can be reduced by incorporating the DRP 28 and appropriately switching the contents of the circuit realized by the DRP 28 to execute various processes.

  In addition, when shooting, an image is recorded as RAW data, and a recording development process is performed after the power is turned off, so that a shooting interval can be shortened and a comfortable shooting environment can be realized.

  In addition, by not performing recording development processing during shooting, power consumption can be suppressed and long-time shooting can be realized.

  In addition, when performing development processing for recording, it is confirmed that a stable power supply (power supply from the AC adapter) is ensured and executed, so that the battery runs out during processing and data Can be prevented in advance. Thereby, the image data obtained by photographing can be handled safely.

  When the AC adapter 56 is connected, the power supply is switched from the battery 52 to the AC adapter 56. However, the battery 52 may be charged while the battery 52 is charged.

  Further, by adopting a configuration in which development processing is performed after the power is turned off, it can be used comfortably without causing a processing waiting time during use.

  In the above-described embodiment, as the recording development process, after the synchronization process, YC conversion is performed, and the YC converted image data (YC data) is subjected to noise reduction process, contrast enhancement process, and edge enhancement process. However, the content of the development process for recording is not limited to this. Further, high-level image processing may be performed to generate image data for recording.

  Similarly, in the above embodiment, only the synchronization processing is performed for the simple development processing for display. However, in order to improve the image quality of the display image, other image processing may be performed. . However, as the processing content is increased, the circuit scale is increased, the power consumption is increased, and the processing speed is decreased. Therefore, it is preferable to set the content of the simple development processing in consideration of these.

  On the other hand, since the development process for recording is performed after the power is turned off, the power consumption, the processing speed, etc. need not be considered much. Therefore, it may be configured to perform higher level image processing.

  Also, since the development process for recording is performed on the condition that a stable power supply is secured, when performing the development process for recording, the operating frequency of the internal circuit is increased to increase the processing speed. Also good.

  In the above embodiment, the RAW data obtained by the actual photographing is subjected to the correction processing unique to the image sensor and recorded in the image recording memory 44. The RAW data may be recorded in the image recording memory 44 as it is. In other words, the RAW data taken in via the image input controller 26 may be recorded in the image recording memory 44 as it is.

  It should be noted that general-purpose development processing can be performed regardless of the model of the camera by performing the correction processing unique to the image sensor and recording in the image recording memory 44 as in the above embodiment.

  The developed RAW data may be deleted after the development process is completed, or may be left as it is in the image recording memory 44 after the development process is completed.

  Alternatively, the image data that has been subjected to the simple development process immediately before the main photographing may be acquired and recorded in the image recording memory 44 in association with the RAW data obtained by the main photographing. Accordingly, it is possible to easily confirm what the captured image is until the RAW data obtained by the actual imaging is subjected to the development process for recording. That is, when a playback instruction is given (in playback mode), the captured image can be easily confirmed by displaying the image subjected to the simple development processing on the display device 32.

  In this case, the image data subjected to the simple development processing is stored in the work memory 40 while being overwritten successively until the instruction for the main photographing is given. Then, the image data stored in the work memory 40 when the instruction for the main photographing is given is recorded in the image recording memory 44 together with the RAW data obtained by the main photographing as the image data subjected to the simple development process immediately before the main photographing. To do. The association may be, for example, a method of changing the extension with the same file name or a method of generating a separate management file.

  In this example, the two are associated with each other and recorded in the image recording memory 44. However, since at least what kind of image is recorded in the image recording memory 44 only needs to be confirmed, the association is not performed. It is good.

  The image data subjected to the simple development processing is preferably configured to be automatically deleted when the corresponding RAW data is subjected to the recording development processing.

  Further, the image data subjected to the simple development process immediately before the main photographing may be displayed on the display device 32 after the main photographing so that the image obtained by the main photographing can be easily confirmed. In addition, the photographer may be inquired about the necessity of recording, and the RAW data obtained by the actual photographing may be recorded in the image recording memory 44 only when a recording instruction is given.

  In addition, it is preferable that the circuit information realized by the DRP 28 can be updated as appropriate. That is, it is preferable that the circuit information recorded in the program memory 42 can be updated as appropriate. As a result, the RAW data can be developed using the latest image processing technology. Similarly, image data can be compressed and expanded using the latest compression and expansion processing techniques.

[Second Embodiment]
As described above, a DSC equipped with DRP can always perform development processing of RAW data by using the latest image processing technology by updating circuit information recorded in the program memory.

  In the DSC according to the present embodiment, the development of RAW data is always executed using the latest image processing technology by appropriately updating the information of the circuit realized by the DRP. Specifically, the DSC is connected to a predetermined server to perform development processing for recording, and the server is inquired about the presence or absence of the latest circuit information before development starts. If the latest circuit information exists, the latest circuit information is acquired from the server, the circuit information is updated, and then development processing is started.

  Since the basic configuration as a DSC is the same as that of the DSC of the first embodiment described above, description of the configuration of the DSC is omitted.

  In the present embodiment, the server is a personal computer (PC), and the PC is connected to be communicable via the external communication unit 36.

  Note that the processing at the time of shooting (the processing in FIG. 2) is the same as the DSC processing in the first embodiment described above, so only the processing performed after the power is turned off will be described here.

  FIG. 5 is a flowchart showing a flow of processing operations of the DSC after shifting to the shooting mode.

  If it is determined that the shooting mode has been changed (see FIG. 2: step S10 & step S18), the CPU 14 determines whether or not an instruction to turn off the power has been issued based on the signal from the operation unit 12 (step S40).

  If it is determined that the power-off is not instructed, the CPU 14 determines that the transition to another mode is instructed, and starts processing in the instructed mode (for example, the reproduction mode) (step S51). ).

  On the other hand, when determining that the power is turned off, the CPU 14 determines whether or not the AC adapter is connected based on the information from the power management unit 38 (step S41). If it is determined that the AC adapter is not connected, the CPU 14 ends the process.

  On the other hand, when determining that the AC adapter is connected, the CPU 14 accesses the image recording memory 44 and determines whether or not undeveloped RAW data exists (step S42). If it is determined that there is no undeveloped RAW data, the CPU 14 ends the process.

  On the other hand, if it is determined that there is undeveloped raw data, the connection status of the external communication unit 36 is confirmed, and it is determined whether or not communication with the server (PC) is possible (step S44). If it is determined that the communication with the server is not possible, the CPU 14 ends the process.

  On the other hand, if it is determined that the communication with the server is possible, the server is inquired of whether there is circuit information to be updated. Based on the inquiry result, the presence / absence of circuit information to be updated is determined (step S44).

  The presence / absence of a circuit to be updated is determined by, for example, managing information on each circuit by version, determining whether the version of each circuit is the latest, and determining whether there is circuit information to be updated.

  If there is information on the circuit to be updated, the information on the circuit to be updated is acquired from the server, and the information on the corresponding circuit stored in the program memory 42 is updated (step S46).

  Then, after the update is completed, the development process for recording is started (step S47). If there is no information on the circuit to be updated, the update process is skipped and the development process for recording is started (step S47).

  Since the procedure of the development process for recording is the same as that of the first embodiment DSC described above, detailed description thereof is omitted here, but each process is performed using the latest circuit information.

  When the development process for recording is completed, the CPU 14 reads out the information of the circuit for compressing the image data from the program memory 42, downloads it to the DRP 28, and causes the DRP 28 to realize the function of the compression processing circuit (step S48). Then, the image data for recording stored in the work memory is added to the DRP 28 and compressed. The generated compressed image data is stored in the work memory 40.

  The CPU 14 adds predetermined auxiliary information to the generated compressed image data, generates an image file of a predetermined format, and records it in the image recording memory according to a predetermined recording format (step S49).

  Thereafter, the CPU 14 accesses the image recording memory 44 and determines whether or not undeveloped RAW data exists (step S50). If it is determined that there is no undeveloped RAW data, the process ends.

  On the other hand, if it is determined that there is undeveloped RAW data, the process returns to step S47, and recording development processing is executed on the undeveloped RAW data.

  As described above, in the DSC 10 according to the present embodiment, the development process for recording is performed after confirming the presence or absence of circuit information to be updated. Therefore, the development process for recording is always performed using the latest image processing technology. Can do.

  In this embodiment, a personal computer is used as a device (server) that provides the latest circuit information, but the device that provides the latest circuit information is not limited to this. For example, a dedicated providing device may be prepared, and a DSC may be connected to the providing device to provide the latest circuit information. Further, it may be configured to receive provision of circuit information using a network (for example, the Internet).

  Further, for example, the circuit information providing function may be provided to the cradle 58 and the connection of the circuit information to the cradle 58 may be accepted. In this case, the cradle 58 is provided with a program memory for holding communication functions and circuit information, and the latest circuit information is sequentially recorded in the program memory.

[Third Embodiment]
In the DSCs of the first and second embodiments described above, even when the power is turned off, if the AC adapter is not connected, the development process for recording is not performed. This is to prevent the data from being destroyed due to the battery running out during the development process.

  However, if the battery has a sufficient capacity to develop the undeveloped RAW data, the development process can be performed without destroying the data even if the battery is not connected to the AC adapter.

  Therefore, in the DSC of the present embodiment, the remaining capacity of the battery is confirmed, and RAW data development processing is performed.

  FIG. 6 is a flowchart showing the flow of processing operations of the DSC after shifting to the shooting mode.

  Note that the processing when it is determined that the AC adapter is connected is the same as in the first embodiment described above.

  Therefore, here, a process when it is determined that the AC adapter is not connected will be described.

  If it is determined in step S21 that the AC adapter is not connected, the CPU 14 accesses the image recording memory 44 and determines whether there is undeveloped RAW data (step S60). If it is determined that there is no undeveloped RAW data, the CPU 14 ends the process.

  On the other hand, if it is determined that undeveloped RAW data exists, the battery capacity required to develop all the undeveloped RAW data is calculated (step S61).

  The calculation here is performed by inputting the number of undeveloped raw data to a predetermined function, for example.

  Then, information on the remaining capacity of the current battery is acquired from the power management unit 38, the acquired remaining capacity is compared with the calculated capacity, and development processing of all RAW data is possible with the remaining capacity of the current battery. It is determined whether or not (step S62). That is, it is determined whether or not the current remaining capacity of the battery exceeds the calculated capacity, and it is determined whether or not development processing of all RAW data is possible.

  If it is determined in this determination that development processing of all RAW data is impossible with the current remaining battery capacity, the CPU 14 ends the processing.

  On the other hand, when it is determined that the development process of all the RAW data is possible with the current remaining capacity of the battery, the CPU 14 executes the development process for recording (step S23).

  As described above, the DSC according to the present embodiment detects the current remaining capacity of the battery, and performs processing of RAW data regardless of whether the AC adapter is connected or not if processing can be performed with the current remaining capacity. . Thereby, the development process for recording can be performed efficiently.

  In the above example, it is determined whether the remaining capacity of the current battery exceeds the capacity of the battery necessary for developing all the undeveloped RAW data, and the development process for recording is performed. However, if the battery is charged more than a specified capacity (for example, if it is fully charged), the development process for recording may be performed.

  Alternatively, the number of data that can be developed is calculated from the current remaining capacity of the battery, and the development processing may be performed for the calculated number of data.

[Fourth Embodiment]
In the DSCs of the first and second embodiments described above, it is confirmed that the AC adapter is connected, and the development process for recording is performed. Thereby, it is possible to prevent the battery from running out and the data from being destroyed during the development process.

  However, if the AC adapter 56 is inadvertently detached during the recording development process (including the case where the camera body is removed from the cradle), the data may be damaged.

  Therefore, in the DSC according to the present embodiment, the remaining capacity of the battery is confirmed before the development processing of the RAW data, and if it is determined that the remaining battery capacity is sufficient for the capacity required for the processing, the RAW Develop data.

  Note that the processing at the time of shooting (the processing in FIG. 2) is the same as the DSC processing in the first embodiment described above, so only the processing performed after the power is turned off will be described here.

  7 to 9 are flowcharts showing a flow of processing operations of the DSC after shifting to the shooting mode.

  If it is determined that the shooting mode has been changed (see FIG. 2: step S10 & step S18), the CPU 14 determines whether or not the power supply is instructed based on a signal from the operation unit 12 (step S70).

  If it is determined that the power-off is not instructed, the CPU 14 determines that the shift to another mode is instructed, and starts processing in the instructed mode (for example, the reproduction mode) (step S71). ).

  On the other hand, when determining that the power is turned off, the CPU 14 determines whether the AC adapter 56 is connected based on the information from the power management unit 38 (step S72). If it is determined that the AC adapter 56 is not connected, the CPU 14 ends the process.

  On the other hand, when determining that the AC adapter 56 is connected, the CPU 14 switches the power supply source to the AC adapter 56 (step S73). Thereby, a stable power supply is ensured.

  Thereafter, the CPU 14 accesses the image recording memory 44 and determines whether or not undeveloped RAW data exists (step S74).

  If it is determined that there is no undeveloped RAW data, the CPU 14 starts a charging process as shown in FIG. That is, the power management unit 38 is instructed to charge the battery 52, and the battery 52 is charged with the power supplied from the AC adapter 56 (step S90). Then, based on the output from the power management unit 38, it is determined whether or not the battery 52 is fully charged (step S90), and the process ends when the battery 52 is fully charged. Thus, when the AC adapter 56 is connected when the power is turned off, the battery 52 can be automatically charged, and the battery 52 can be charged efficiently.

  On the other hand, if it is determined in step S74 that undeveloped RAW data exists, the CPU 14 calculates the capacity of the battery required to develop all the undeveloped RAW data (step S75). Then, information on the remaining capacity of the current battery is acquired from the power management unit 38, the acquired remaining capacity is compared with the calculated capacity, and development processing of all RAW data is possible with the remaining capacity of the current battery. It is determined whether or not (step S76). That is, it is determined whether or not the current remaining capacity of the battery exceeds the calculated capacity, and it is determined whether or not development processing of all RAW data is possible.

  If it is determined in this determination that development processing of all RAW data is impossible with the current remaining capacity of the battery, the CPU 14 starts charging processing. That is, the power management unit 38 is instructed to charge the battery 52, and the battery 52 is charged with the power supplied from the AC adapter 56 (step S77). Then, based on the output from the power management unit 38, it is determined whether or not a capacity sufficient to develop all the RAW data has been charged (step S78).

  If it is determined in step S78 and step S76 that all the RAW data can be developed, the CPU 14 executes a recording development process (step S80). Then, the generated image data for recording is compressed (step S81), predetermined attached information is added to the generated compressed image data to generate an image file of a predetermined format, and a predetermined recording format The image is recorded in the image recording memory (step S82).

  Thereafter, the CPU 14 determines whether or not undeveloped RAW data exists (step S83). If the CPU 14 determines that there is no undeveloped RAW data, as shown in FIG. The process is terminated when the battery 52 is fully charged.

  By the way, if the AC adapter 56 is disconnected during the development, compression, and recording processes and the power supply from the AC adapter 56 is cut off, the data being processed may be damaged.

  Therefore, the CPU 14 monitors the connection status of the AC adapter 56 during each development, compression, and recording process. When the CPU 14 detects that the AC adapter 56 has been removed, the CPU 14 immediately determines the power supply source as shown in FIG. Switching to the battery 52 (step S100), the process is continued (step S101).

  Here, in the DSC according to the present embodiment, it is confirmed that a sufficient capacity for developing all RAW data is secured, and the developing process is started. Sufficient capacity is secured to develop all RAW data. Therefore, the capacity of the battery 52 is not lost during the processing, and the data can be processed safely.

  As described above, when it is detected that the AC adapter 56 has been removed, the power supply source is immediately switched to the battery, and the processing is continued.

  Thereafter, the CPU 14 determines whether or not the development processing for all the RAW data has been completed (step S102). If the CPU 14 determines that the development for all the RAW data has been completed, as shown in FIG. The charging process is performed, and the process is terminated when the battery 52 is fully charged.

  As described above, in the DSC according to the present embodiment, even when the AC adapter is connected, if the development processing of all the RAW data is impossible with the current remaining capacity of the battery, the development processing is not performed. Then, development processing is performed after the battery is charged. As a result, even if the AC power supply is inadvertently cut off, the development process can be performed safely without destroying the data.

  In the above example, after the battery 52 is charged, when the development process for recording is started, the battery capacity necessary for developing all the undeveloped raw data is charged. Although the development process is started, the development process may be started after the battery is fully charged.

  In the above example, the battery capacity required to develop all the undeveloped RAW data is calculated (step S75), information on the current remaining battery capacity is acquired from the power management unit 38, The development processing for recording is performed when the development processing of all RAW data is possible with the remaining capacity of the battery, but it is determined whether or not the battery 52 is charged more than a specified capacity (for example, full charge) The recording development process may be performed when the battery is charged more than a specified capacity. In this case, when the AC power is cut off, only the data being processed may be subjected to development, compression, and recording processing.

[Other embodiments]
In the above-described series of embodiments, the development process for recording is performed when the power is turned off by the power button. However, even if the power is not turned off by the power button, no operation is performed. When the state has passed for a certain period of time, the power supply may be automatically turned off to perform a development process for recording.

  Alternatively, when the attachment to the cradle 58 is detected and attached to the cradle 58, the power may be automatically turned off to perform the recording process.

  In the series of embodiments described above, the development processing for recording is performed on the RAW data obtained by the actual photographing. However, the RAW data may be stored in the image recording memory 44 as it is. That is, the development recording mode and the RAW recording mode can be selected as the image recording mode so that the actual shooting can be performed, and the RAW data actually shot in the RAW recording mode is recorded as it is without being developed. The data is stored in the memory 44.

  Similarly, even when performing development processing for recording, it is configured so that a mode for recording by compression and a mode for recording in an uncompressed state can be selected, and a mode for recording in an uncompressed state is selected. In such a case, the image data may be recorded in the image recording memory 44 without performing the compression process.

  In the series of embodiments described above, the case where the present invention is applied to the DSC has been described as an example. However, the application of the present invention is not limited to this. The present invention can be similarly applied to a device having a photographing function such as a so-called camera-equipped mobile phone.

  In the series of embodiments described above, DRP is adopted as dynamically reconfigurable hardware. However, usable dynamically reconfigurable hardware is not limited to this. Absent.
