  The non-volatile memory 119 stores various programs such as a program for performing imaging processing, a program for performing image processing, and a program for recording image file data created on the recording medium 200 on the recording medium 200. The nonvolatile memory 119 stores various programs such as an OS that implements and executes a multitask configuration of the program, and adjustment values for performing various controls.

  The release switch 120 is turned on (SW1) by half-pressing the release button (first stroke), and instructs to start a shooting preparation operation such as AF (autofocus) processing, AE (automatic exposure) processing, and the like. The release switch 120 is turned on (SW2) when the release button is fully pressed (second stroke), and instructs the start of a series of processes including an imaging process, a white balance correction process, a development process, and a recording process. In the imaging process, the signal read from the image sensor 105 is written into the memory 113 via the A / D converter 106 and the memory control circuit 111. In the white balance correction process, the white balance is corrected according to the white balance mode set for the image data using the image processing circuit 107. In the recording process, the developed image data is read from the memory 113, compressed by the compression / decompression circuit 114, and written to the recording medium 200.

  The menu operation switch 121 includes a combination of a reproduction key (reproduction button), a menu key (menu button), a set key, and a cross key (not shown).

  In the present embodiment, the control unit 123 and the connector 124 are one system for the recording medium 200. However, the control unit 123 and the connector 124 may be a plurality of systems. The connector 124 may be combined.

  Here, in the present embodiment, for example, an HDD is used as the recording medium 200, and the recording medium 200 is externally connected to the digital camera 100 and uses a USB connection as a connection form.

  The recording medium 200 is an interface with a recording medium unit 203 composed of a magnetic disk and the digital camera 100. I have.

  The control unit 202 has a device controller for causing the recording medium 200 to realize the function of the USB connection device.

Connected. The control unit 123 on the digital camera 100 side can communicate with the control unit 202 on the recording medium 200 side via a USB cable, and can supply power to the recording medium 200.

  Next, an operation example of the digital camera 100 having the above configuration will be described with reference to FIGS. 2 to 6 are executed by the CPU of the microcomputer 127 by loading a processing program stored in a predetermined storage area (ROM, hard disk, etc.) into the RAM.

(Main sequence)
FIG. 2 is a flowchart for explaining the main sequence of the operation of the digital camera 100. In FIG. 2, a series of processing from photographing to recording and display processing and a sequence of the power saving mode of the recording medium 200 will be described. A state where power is supplied to the recording medium 200 is referred to as a normal mode. Each process in FIG. 2 is processed in a multitask configuration.

  First, in step S201, it is determined whether or not the SW1 that is turned on when the release switch 120 is half-pressed is operated to instruct the start of the photographing operation. If SW1 is not operated, the process proceeds to step S202. In step S202, it is determined whether the menu operation switch 121 has been operated to instruct display on the display unit 110. If the menu operation switch 121 has not been operated, the process proceeds to step S203.

  In step S203, it is determined whether or not the power saving timer has elapsed a predetermined time. Here, the power saving timer measures the elapsed time when the digital camera 100 is not instructed to shoot by the release switch 120 or the display operation by the menu operation switch 121 or the like and has no access to the recording medium 200. To do.

  If it is determined in step S203 that the power saving timer has not reached the predetermined time, the sequence from step S201 is repeated. On the other hand, if the power saving timer has elapsed in step S203, the process proceeds to step S204, and the recording medium 200 is set in the power saving mode. If the recording medium 200 is already in the power saving mode, the power saving mode is maintained. In the power saving mode, power supply to the recording medium 200 is stopped, and the operation of the recording medium 200 is stopped.

  In the present embodiment, the power saving mode of the recording medium 200 can operate independently of the power saving mode of the digital camera 100. That is, even when the digital camera 100 is being used, only the recording medium 200 can enter the power saving mode, effectively reducing the power consumption of the entire system.

  Next, in step S201, when SW1 that is turned on by half-pressing the release switch 120 is operated to instruct the start of the shooting operation, in step S211, the activation process is performed according to the state of the recording medium 200. Instruct. A sequence for the activation process of the recording medium 200 will be described later with reference to FIG.

  In step S211, when the activation of the recording medium 200 is instructed, the process proceeds to step S205 without waiting for the completion of the activation process of the recording medium 200. If the display is performed by the display unit 110, the display is terminated. Next, the process proceeds to step S206, and photographing processing is executed. That is, the startup process of the recording medium 200 and the shooting process are executed in parallel. The photographing process will be described later with reference to FIG.

  When the photographing process is completed in step S206, the process proceeds to step S207, and a recording process for recording the image file created by the photographing process on the recording medium 200 is performed. The recording process will be described later with reference to FIG. When the recording process ends, the process proceeds to step S208, where the power saving timer is cleared and measurement of a predetermined time is started.

  Note that when the recording medium 200 is a USB-connected external recording medium as in the present embodiment, it takes several seconds to several tens of seconds from when the recording medium 200 starts to be supplied to the writable normal mode. However, since each process is processed in parallel as control of the multitask configuration, the photographing process is repeatedly executed regardless of the activation state of the recording medium 200.

  Next, when the menu operation switch 121 is operated in step S202 and a display on the display unit 110 is instructed, the process proceeds to step S209, and a display process is executed. The display process will be described later with reference to FIG. When the display process is finished in step S209, the process proceeds to step S210, and the state of the display unit 110 is confirmed.

  If it is determined in step S210 that image data is being reproduced and displayed on the display unit 110, the process returns to step S201 and the sequence is repeated. If no display is made on the display unit 110 in step S210, the process proceeds to step S208, the power saving timer is cleared, and measurement of a predetermined time is started.

(Shooting process)
Next, with reference to FIG. 3, the photographing process in step S206 in FIG. 2 will be described.

  When SW1 is pressed by the operation of the menu operation switch 121 and the photographing process is executed, autofocus control is performed by the distance measuring circuit 117 and the lens control circuit 101a in step S301, and the focusing lens is set to the in-focus position. Control.

  Next, in step S302, a photometric operation is performed using the photometric circuit 118, and a shutter control value and an aperture value to be controlled are determined according to the set photographing mode. Next, in step S303, the mirror control circuit 116 is instructed to cause the quick return mirror 102 to be retracted out of the photographing optical path, so-called mirror up, and in step S304, accumulation in the image sensor 104 is started.

  Next, in step S305, the shutter control circuit 115 is instructed to run the shutter to perform exposure (step S306). Next, in step S307, the shutter control circuit 115 is instructed to close the shutter, and in step S308, accumulation of the image sensor 105 is terminated.

  In step S 309, an image signal is read from the image sensor 105, and image data processed by the A / D converter 106 and the image processing circuit 107 is temporarily stored in the memory 113. When all the image signals are read from the image sensor 105, in step S310, the mirror control circuit 116 is instructed to cause the quick return mirror 102 to return to the photographing optical path. In step S311, image data obtained by performing a predetermined development process on the image signal is created, and the photographing process is terminated.

(Recording process)
Next, the recording process in step S207 in FIG. 2 will be described with reference to FIG.

  First, in step S401, it is determined whether or not the recording medium 200 has been restored from the power saving mode and the startup process enabling reading / writing to the recording medium 200 has been completed. If the activation process is not completed in step S401, the activation process is awaited. When the activation process is completed in step S401 and the normal mode is set, the process proceeds to step S402. In step S402, the image data temporarily stored in the memory 113 is written and stored under the folder structure hierarchy having a predetermined rule in the recording medium 200, and the recording process is terminated.

(Recording medium activation process)
Next, a recording medium activation process (step S211 in FIG. 2) for returning the recording medium 200 from the power saving mode to the usable normal mode will be described with reference to FIG.

  First, in step S501, it is determined whether or not the recording medium 200 is in the power saving mode. If it is determined in step S501 that the recording medium 200 is not in the power saving mode, the recording medium 200 is already in the normal mode, and the mounting process enabling reading / writing to the recording medium 200 is completed. The activation process of the recording medium 200 is terminated. On the other hand, if it is determined in step S501 that the recording medium 200 is in the power saving mode, the process proceeds to step S502, power supply to the recording medium 200 is started, and connection of the recording medium 200 is detected (step S503).

  If the connection of the recording medium 200 is detected in step S503, the process proceeds to step S504, where a known mount process is performed so that reading / writing to the recording medium 200 is possible, and the recording medium activation process is terminated.

  Thus, in this embodiment, prior to the recording process, the activation process of the recording medium 200 is started in accordance with the operation of the release switch 120, and the activation process is performed in parallel with the photographing process. For this reason, it is possible to shorten the time until writing is possible, compared to the case where the activation process is performed when writing to the recording medium 200 becomes necessary.

(Display processing)
Next, with reference to FIG. 6, a process of reading out image data recorded on the recording medium 200 and reproducing it on the display unit 110, and a display process of setting menu items (step S209 in FIG. 2) will be described. . When the playback key and menu key of the menu operation switch 121 are operated, display processing on the display unit 110 is performed. Display processing on the display unit 110 includes reproduction of image data and display of setting menu items.

  First, in step S601, it is determined whether or not the playback key has been operated. If it is determined in step S601 that the reproduction key has been operated, the process advances to step S602 to determine whether or not an image is being reproduced. If it is determined in step S602 that the image is not being reproduced, the process proceeds to step S603, and the recording medium 200 is activated. When the activation process is completed, the process proceeds to step S604.

  In step S604, image data is read from the recording medium 200 to the image display memory 112, and in step S605, the display control circuit 109 is controlled to reproduce and display the image data on the display unit 110, thereby reproducing the image data. When the reproduction is completed, the display process is terminated while maintaining the reproduction state.

  If it is determined in step S602 that the image is being reproduced, the process proceeds to step S606, where the image reproduction on the display unit 110 is terminated, and the series of display processes is terminated. In other words, the display process is continued while the image is reproduced on the display unit 110.

  Next, when it is determined in step S601 that the reproduction key has not been operated, the process proceeds to step S607 to determine whether or not the menu key has been operated. If it is a menu key operation, the process proceeds to step S608, where it is determined whether or not the menu is being displayed. If the menu is not being displayed, the process proceeds to step S609 and the menu is displayed. Next, in step S610, processing is performed according to the menu selection operation.

  With the menu selection operation, a desired item can be selected by operating the cross key and the set key, and a setting process corresponding to the selected menu item is executed. Among the menu items, there are prepared items for processing image data such as rotation processing and designation of an image to be printed on the image data recorded on the recording medium 200. In that case, since processing is performed on the file in the recording medium 200, processing is performed after completion of activation of the recording medium 200. When the menu selection process ends, the display process ends.

  If the menu is being displayed in step S608, the process proceeds to step S606, the menu display on the display unit 110 is terminated, and the series of display processes is terminated. That is, the display process is continued while the menu is reproduced on the display unit 110.

  If it is determined in step S607 that the menu key has not been operated, the process proceeds to step S611 to determine whether or not the cross key has been operated. If it is a cross key operation, the process advances to step S612 to determine whether or not an image is being reproduced. If the image is being reproduced, the process proceeds to step S604, and one of the images before and after the currently reproduced image is read according to the operation of the cross key, and the image is reproduced.

  If it is determined in step S612 that the image is not being reproduced, the process advances to step S613 to determine whether the menu is being displayed. If the menu is being displayed, the process advances to step S610, and the microcomputer 127 performs menu selection operation processing. If it is determined in step S611 that the cross key is not operated, a series of display processing ends.

  As described above, in this embodiment, once the display process is started, the display process is continued until the display end operation is performed. While the display process continues, the power saving mode of the recording medium 200 is stopped and the normal mode is continued. That is, when the image reproduction is repeatedly performed, or when the menu selection operation is repeatedly performed, the recording medium 200 is prohibited from entering the power saving mode. Therefore, for example, every time a reproduction image selection operation (S611, S612) is performed by operating the cross key, image reproduction, power saving mode, cross key operation, waiting for completion of activation processing, image reading, image reproduction, and the like are performed. There is no need to wait for the activation process of the recording medium 200 every time. The same applies to the menu selection process.

  As described above, in the present embodiment, control is performed so as to shift to the power saving mode when there is no access to the recording medium 200 for a predetermined time. Thereby, the power consumption of the whole system can be effectively suppressed.

  When the recording medium 200 is in the power saving mode, the recording medium 200 is activated in response to an instruction to start a shooting operation. Accordingly, it is possible to prevent a delay in the image data recording process due to the slow start of the recording medium 200.

  Further, the activation process of the recording medium 200 is performed in response to an instruction to start the reproduction operation. Accordingly, it is possible to prevent delays such as reading of image data in the recording medium 200, processing for changing to the image data, and access to the recording medium 200 due to the slow start of the recording medium 200.

  Furthermore, activation of the power saving mode of the recording field 200 is controlled according to the state of the display unit 110. That is, when image data is displayed or menu items are displayed on the display unit 110, there is a high possibility of access to the recording medium 200, so that the power saving mode is stopped and the normal mode is continued. I have to. As a result, delays such as reading of image data in the recording medium 200, processing for changing to the image data, and access to the recording medium 200 due to the slow start of the recording medium 200, such as when repeatedly displaying images. Can be prevented.

  As described above, in this embodiment, since the activation process from the power saving mode of the recording medium 200 is performed according to the shooting operation and the reproduction operation, the user can automatically save power without being aware of the power saving operation. It is possible to enter the mode. Therefore, by appropriately performing control from the normal mode to the power saving mode and from the power saving mode to the normal mode, the digital camera can achieve both reduction in power consumption and improvement in operability.

  In the present embodiment, the USB-connected HDD is exemplified as the recording medium. However, other connection forms and other recording media such as an optical disk may be used.

I have.

  The recording medium 300 may be configured to be entirely accommodated in the casing of the digital camera 100 or may be configured to be connected to the outside of the casing of the digital camera 100 via a cable or the like. The entire structure is accommodated in the housing of the digital camera 100. On the other hand, the recording medium 200 is an HDD as an external recording medium that is USB-connected to the outside of the housing of the digital camera 100, as in the first embodiment.

  In addition, the control unit 123 on the digital camera 100 side and the control unit 202 on the recording medium 200 side can communicate with each other via the USB cable and can supply power to the recording medium 200, and power supply is stopped only to the recording medium 200. A power saving mode is implemented.

  Here, in the following description, the recording medium 200 may be referred to as an HDD 200 and the recording medium 300 may be referred to as a memory card 300. Further, the user can designate a recording medium for recording image data from the HDD 200 and the memory card 300, and the designated recording medium is called a current medium.

  The user performs a designation operation to designate a recording medium for recording image data. FIG. 8 shows a state in which menu items for specifying the recording medium are displayed on the display unit 110. The user selects from the selection items of “memory card” using the memory card 300 as the current medium and “external recording device” using the HDD 200 as the current medium.

  A case where the HDD 200 is selected as the current medium will be described. First, “external recording device” is selected in the image data recording medium selection menu shown in FIG. 8A, and the image quality of the image data stored in the “external recording device” is selected in the menu shown in FIG. 8B. select. The image quality of the image data is “L”, “M”, “S” having different sizes and compression ratios as JPEG data developed by the image processing circuit 107, and raw data of the image sensor 105 before development processing. A certain “RAW” can be designated.

  Next, an operation example of the digital camera 100 having the above configuration will be described with reference to FIGS. Here, each processing in FIGS. 9 to 11 is executed by the CPU of the microcomputer 127 by loading a processing program stored in a predetermined storage area (ROM, hard disk, etc.) into the RAM.

(Main sequence)
FIG. 9 is a flowchart for explaining the main sequence of the digital camera according to the present embodiment. In particular, FIG. 9 is a diagram for explaining a series of processing from photographing to recording and display processing, and a sequence of the power saving mode of the HDD 200. Each process in FIG. 9 is processed in a multitask configuration.

  First, in step S1001, it is determined whether or not the SW1 that is turned on when the release switch 120 is pressed halfway is operated to instruct the start of the photographing operation. If SW1 is not operated, the process proceeds to step S1002, and it is determined whether or not the menu operation switch 121 is operated and display is instructed to the display unit 110. Note that the menu operation switch 121 here is for a reproduction switch and determines its operation. That is, it is determined whether or not the reproduction of the image data in the recording medium is instructed. If the menu operation switch 121 is not operated, the process proceeds to step S1003.

  In step S1003, it is determined whether a predetermined time has elapsed for the power saving timer. Here, the power saving timer measures the elapsed time when the digital camera is not instructed by the release switch 120, the menu operation switch 121, and the like and the HDD 200 is not accessed. If it is determined in step S1003 that the power saving timer has not reached the predetermined time, the sequence from step S1001 is repeated.

  On the other hand, if it is determined in step S1003 that the power saving timer has elapsed a predetermined time, the process advances to step S1004 to set the HDD 200 in the power saving mode. If the HDD 200 is already in the power saving mode, the power saving mode is maintained. In this power saving mode, power supply to the HDD 200 is stopped and the operation of the HDD 200 is stopped. In the present embodiment, the power saving mode of the HDD 200 can operate independently of the power saving mode of the digital camera 100 main body. That is, even when the digital camera 100 is being used, only the HDD 200 can enter the power saving mode, effectively reducing the power consumption of the entire system.

  Next, in step S1001, when SW1 that is turned on by half-pressing the release switch 120 is operated to instruct to start the shooting operation, the current media designation state is determined (discriminated) (S1015). The HDD 200 is instructed to start up according to the determination result (S1016). Since the sequence of the HDD 200 activation process is the same as that in the first embodiment, description thereof is omitted.

  If the start of the HDD 200 is instructed in step S1016, the process proceeds to step S1005 without waiting for the end of the start process of the HDD 200, and if the display is performed by the display unit 110, the display is stopped. Subsequently, the process proceeds to step S1006, and the photographing process is executed. Since the imaging process is the same as that in the first embodiment, description thereof is omitted here. In step S1006, when the shooting process ends, the process proceeds to step S1007, and a recording process for recording the image data created in the shooting process on the recording medium 200 is performed. This recording process will be described later with reference to FIG. When the recording process ends, the process proceeds to step S1008, where the power saving timer is cleared and measurement of a predetermined time is started.

  Next, in step S1002, when the menu operation switch 121 is operated and display on the display unit 110 is instructed, the process proceeds to step S1010, and display processing is executed. The display process will be described later with reference to FIG. When the display process ends in step S1010, the process proceeds to step S1011 to determine the state of the display unit 110 and perform power saving control. Specifically, it is determined in step S1011 whether the menu is being displayed. If it is determined in step S1011 that the menu is being displayed, the process returns to step S1001. In other words, the HDD 200 is maintained in the normal mode.

  On the other hand, if it is determined in step S1011 that the menu is not being displayed, it is determined in step S1012 whether an image is being reproduced. If the image is being reproduced, it is determined in step S1013 whether the current medium is designated in the HDD 200 or not. If the current medium is HDD 200, the process returns to step S1001. That is, if an image is being reproduced and the current medium is HDD 200, HDD 200 is maintained in the normal mode. If the image is not being reproduced (No in step S1012), if the current medium is not the HDD 200 (No in step S1013), the process proceeds to step S1014, the power saving timer is cleared, and measurement of a predetermined time is started.

(Recording process)
Next, with reference to FIG. 10, the recording process (step S1007 in FIG. 9) of the image data created by the photographing process onto the recording medium will be described.

  First, in step S1101, it is determined whether the current medium is the HDD 200 or not. If the current medium is the HDD 200, the process advances to step S1102, and it is determined whether the HDD 200 has completed the return from the power saving mode and has completed the start-up process enabling reading / writing to the recording medium. If the startup process has not been completed, wait for the startup process to be completed. When the startup process is completed and the normal mode is set, the process proceeds to step S1103. In step S1103, the image data temporarily stored in the memory 113 is stored under the folder structure hierarchy having a predetermined rule in the HDD 200, and the recording process is terminated.

  If it is determined in step S1101 that the current medium is not the HDD 200, the process advances to step S1104. In step S1104, the image data temporarily stored in the memory 113 is stored under the folder structure hierarchy having a predetermined rule in the memory card 300, and the recording process is terminated.

(Display processing)
Next, with reference to FIG. 11, a process of reading out image data recorded on a recording medium and reproducing it on the display unit 110, and a display process of setting menu items (step S1010 in FIG. 9) will be described.

  First, in step S1201, it is determined whether or not the playback key of the menu operation switch 121 has been operated. If the operation is a reproduction key operation, the process advances to step S1202 to determine whether or not an image is being reproduced. If playback is not in progress, the process advances to step S1203 to determine whether the current medium is the HDD 200. If the current medium is the memory card 300, the process proceeds to step S1205. On the other hand, if the current medium is the HDD 200, the HDD 200 is activated in step S1204, and the HDD 200 is activated from the power saving mode to the normal mode. When the activation process is completed, the process proceeds to step SS1205.

  In step S1205, the image data is read from the current medium (from the HDD 200 for the HDD 200, to the memory card 300 for the memory card 300) to the image display memory 112. In step S1206, the display control circuit 109 is controlled to reproduce and display the image data on the display unit 110. The image data is reproduced, and when the reproduction is completed, the display process is terminated while maintaining the reproduction state. If it is determined in step S1202 that the image is not being reproduced, the process proceeds to step S1207, where the image reproduction is terminated and the display process is terminated.

  If it is determined in step S1201 that the playback key has not been operated, the process advances to step S1208 to determine whether or not the menu key has been operated. If it is a menu key operation, the process advances to step S1209 to determine whether a menu is being displayed. If the menu is not being displayed, the HDD 200 is instructed to start (step S1215), and the process proceeds to step S1210 without waiting for the end of the HDD 200 start-up process to display the menu item.

  Subsequently, the process proceeds to step S1211, and processing is performed according to a menu selection operation. Here, if the process is performed on a file in the HDD 200, the process is performed after completion of the startup of the HDD 200. For example, this process may be a process of copying image data from the memory card 300 to the HDD 200. Even when the HDD is not the current medium, the HDD 200 is activated by operating the menu operation key, so that the process is faster. Processing can be performed. Here, when the menu selection process is completed, the display process is terminated while maintaining the display state of the menu items. If the menu item is being displayed in step S1209, the process advances to step S1207 to end the menu item display on the display unit 110 and end the display process.

  If it is determined in step S1208 that the menu key has not been operated, the process advances to step S1212 to determine whether or not the cross key has been operated. If it is a cross key operation, the process advances to step S1213 to determine whether an image is being reproduced. If the image is being reproduced, the process advances to step S1205, and one of the images before and after the currently reproduced image is read according to the operation of the cross key, and the image is reproduced.

  If it is determined in step S1213 that the image is not being reproduced, the process advances to step S1214 to determine whether the menu is being displayed. If the menu is being displayed, the process advances to step S1211 to perform menu selection operation processing. If it is determined in step S1212 that the operation of the cross key is not performed, the series of display processing ends.

  As described above, in the present embodiment, when a plurality of recording media are used, the power saving mode of the recording medium is controlled based on the designated state of the recording medium on which the image data is recorded.

  That is, when the HDD 200 is designated as a recording medium, the power saving mode of the HDD 200 is stopped and the normal mode is continued while the reproduction process is continued. In addition, when the reproduction of image data in the HDD 200 is repeatedly performed, or when the menu selection operation is repeatedly performed, the recording medium is prohibited from entering the power saving mode. Therefore, for example, every time a playback image selection operation (S1112, S1113, S1105) is performed by operating the cross key, image playback, power saving mode, cross key operation, waiting for completion of activation processing, image reading, image playback, etc. There is no need to wait for a recording medium activation process. The same applies to the menu selection process.

  When the HDD 200 is not designated as a recording medium, the power saving mode of the recording medium is continued even if a shooting operation is performed. Therefore, it is possible to save power consumption without performing unnecessary processing.

  As described above, in this embodiment, the power saving control of the recording medium 200 is performed according to the designated state of the recording medium. That is, when the HDD 200 is the current medium, the HDD 200 is activated in response to an instruction to start the shooting operation. Accordingly, it is possible to prevent a delay in the image data recording process due to the slow start of the recording medium.

  Also, the HDD 200 is activated in response to an instruction to start the reproduction operation. As a result, it is possible to prevent delays such as reading of image data in the HDD 200, processing for changing to image data, and access to the HDD 200 due to the slow start of the recording medium.

  Further, activation of the power saving mode of the HDD 200 is controlled according to the state of the display unit 110. That is, when image data is displayed or menu items are displayed on the display unit 110, since the possibility of access to the HDD 200 is high, the power saving mode is stopped and the normal mode is continued. . Accordingly, it is possible to prevent delays such as reading of image data in the HDD 200, processing for changing to the image data, and access to the HDD 200 due to the slow start of the recording medium, such as when repeatedly displaying images. .

  Further, when the HDD 200 is not the current medium, the power saving mode is continued without starting the HDD 200 in response to an instruction to start the shooting operation. As a result, power consumption can be reduced without using unnecessary power.

  Further, the power saving mode is continued without starting the HDD 200 in response to an instruction to start the reproduction operation by the reproduction key operation. Thereby, power consumption can be reduced without using unnecessary power.

  Furthermore, the HDD 200 is activated in response to an instruction to start a reproduction operation by a menu key operation. Accordingly, it is possible to prevent delays such as reading of image data in the HDD 200, processing for changing to the image data, and access to the HDD 200 due to the slow start of the HDD 200.

  Further, activation of the power saving mode of the HDD 200 is controlled according to the state of the display unit 110. That is, when the menu item is displayed on the display unit 110 by a menu operation, since the possibility of access to the HDD 200 is high, the power saving mode is stopped and the normal mode is continued. Accordingly, it is possible to prevent delays such as reading of image data in the HDD 200, change processing to the image data, access to the HDD, and the like due to the slow start of the HDD, such as when repeatedly displaying images.

  As described above, in the present embodiment, since the start processing from the power saving mode of the recording medium is performed according to the recording medium designation state, the shooting operation, and the reproduction operation, the user is not aware of the power saving operation. It is possible to automatically enter the power saving mode. Therefore, by appropriately performing control from the normal mode to the power saving mode and from the power saving mode to the normal mode, the digital camera can achieve both reduction in power consumption and improvement in operability.

  In this embodiment, control is performed so that the power saving mode is used only for the HDD, but the power saving mode may also be applied to a memory card.

  In the present embodiment, the power saving mode is prohibited in accordance with the state of the display unit 110. However, the power saving timer may be extended more than usual. For example, if the power saving timer is 5 seconds, control such as extending it to 30 seconds is possible.

  Furthermore, in the present embodiment, the USB-connected HDD is exemplified as the external recording medium, but other connection forms and other external recording media such as an optical disk may be used.

  Furthermore, in the present embodiment, one of the two recording media can be designated as the current medium. However, it may be possible to simultaneously record on the two recording media. In this case, according to the shooting operation. Any recording medium is controlled to be in the normal mode.

(Third embodiment)
Next, a digital camera which is a third embodiment of the present invention will be described with reference to FIGS. Note that portions overlapping or corresponding to those in the first embodiment will be described using the reference numerals.

  The digital camera of the present embodiment includes means for selecting whether or not to use the power saving mode of the recording medium in the first embodiment or the second embodiment.

  FIG. 12 is a diagram showing an example of a screen for selecting the use of the power saving mode of the recording medium, which is displayed on the display unit 110 and the mode is selected by the user.

  Here, the selection item “do not use” 1201 is an item to be selected when the power saving mode is not used, and the power saving mode becomes invalid. In this case, the normal mode is maintained for the recording medium, and the response priority mode is set.

  The selection item “power saving mode 1” 1202 is an item to be selected when the power saving mode is used, and the control thereof is the control described in the first embodiment or the second embodiment.

  A selection item “power saving mode 2” 1203 is an item to be selected when the power saving mode is used, and the control is an item for selecting a mode for performing control for further reducing power consumption than “power saving mode 1”. It is.

  Next, the operation of the digital camera when “power saving mode 2” is selected on the screen of FIG. 12 will be described.

(Main sequence)
FIG. 13 is a flowchart for explaining the main sequence of the operation of the digital camera according to the present embodiment. In particular, FIG. is there. Here, each processing in FIG. 13 is executed by the CPU of the microcomputer 127 by loading a processing program stored in a predetermined storage area (ROM, hard disk, etc.) into the RAM.

  First, in step S1301, it is determined whether or not the SW1 that is turned on when the release switch 120 is pressed halfway is operated to instruct the start of the shooting operation. If SW1 is not operated, the process proceeds to step S1302, and it is determined whether the menu operation switch 121 is operated and display on the display unit 110 is instructed. If the menu operation switch 121 is not operated, the process proceeds to step S1303. In step S1303, it is determined whether the power saving timer has elapsed a predetermined time. If it is determined in step S1303 that the power saving timer does not reach the predetermined time, the sequence from step S1301 is repeated.

  On the other hand, when the power saving timer has elapsed in step S1303, the process proceeds to step S1304. If the display is performed by the display unit 110, the display is terminated, and the process proceeds to step S1305, where the recording medium 200 is set in the power saving mode. And If the recording medium 200 is already in the power saving mode, the power saving mode is maintained. In this power saving mode, power supply to the recording medium 200 is stopped and the operation of the recording medium 200 is stopped.

  Next, in step S1301, when SW1 that is turned on by half-pressing the release switch 120 is operated and an instruction to start a photographing operation is given, the process proceeds to step S1306, and if the display is performed by the display unit 110, the display is displayed. finish. Next, the process proceeds to step S1307, and photographing processing is executed. When the photographing process ends in step S1307, the process proceeds to step S1308, where the recording medium 200 is activated, and the recording medium 200 is activated from the power saving mode to the normal mode. When the activation process is completed, the process advances to step S1309, and a recording process for recording the image file created by the photographing process on the recording medium 200 is performed. Since this recording process is the same as that in the first embodiment, a description thereof will be omitted. When the recording process ends, the process proceeds to step S1310, where the power saving timer is cleared and measurement of a predetermined time is started.

  Next, when the menu operation switch 121 is operated in step S1302 to instruct display on the display unit 110, the process proceeds to step S1311 and display processing is executed. Since this display processing is the same as that in the first embodiment, description thereof is omitted. When the display process ends in step S1311, the process proceeds to step S1310, where the power saving timer is cleared and measurement of a predetermined time is started. Thereafter, the process returns to step S1301, and the sequence is repeated.

  As described above, in the present embodiment, when “power saving mode 2” is selected, the power saving timer is started when reading and writing to the recording medium 200 are completed regardless of the state of the display unit 110. The recording medium 200 is controlled to enter the power saving mode. Therefore, the user can select a means for reducing power consumption.

  In the description of FIG. 13, the case where there is one recording medium as in the first embodiment has been described, but the present invention is not limited to this, and a plurality of recording media are used as in the second embodiment. It is also applicable to cases.

  As described above, in this embodiment, the user can select the power saving mode. For this reason, when “not use” is selected as the power saving mode, the same operability as that of the memory card is possible even with a slow-starting recording medium.

  In addition, when “power saving mode 1” is selected, since the start processing from the power saving mode of the recording medium is performed in accordance with the shooting operation and the reproduction operation, the user is automatically conscious of the power saving operation. It is possible to enter the power saving mode. Therefore, by appropriately performing control from the normal mode to the power saving mode and from the power saving mode to the normal mode, the digital camera can achieve both reduction in power consumption and improvement in operability.

  Further, when “power saving mode 2” is selected, it is possible to further reduce power consumption. When “power saving mode 2” is selected, the control performs the startup process from the power saving mode of the recording medium according to the shooting operation and the reproduction operation, so that the user is not aware of the power saving operation. It is possible to automatically enter the power saving mode. Therefore, by appropriately performing control from the normal mode to the power saving mode and from the power saving mode to the normal mode, the digital camera can achieve both reduction in power consumption and improvement in operability.

  In each of the above embodiments, the recording medium is configured to be connectable to the digital camera. However, an adapter device that expands the function is configured to be connectable to the digital camera, and recording is performed on the recording medium via the adapter device.
