When the system controller 50 writes data to the recording medium 200/210, first, when recording a captured still image or moving image, secondly, specify the print contents of the recorded image. When various data is written to create a file to be recorded on the recording medium 200/210, a third case is a system process for writing an identification name of a file or image recorded on the recording medium. In the present embodiment, power control will be described by taking as an example the case of creating a file for specifying print contents.

  The power supply control unit 80 detects the supply voltage and performs monitoring. When the system control unit 50 starts file access to the recording medium 200 in response to an operation instruction from the operation unit, the program of FIG. 2 is started (S201). The system control unit 50 sets the detected power supply voltage value V from the power supply control unit 80 (S202), and compares the power supply voltage value V with the voltage warning level L1 (S203).

  If the power supply voltage value V has not reached the warning level L1, access processing to the recording medium 200 is executed (S207), and the processing procedure is terminated.

  On the other hand, when there is a relationship of V <L1, a comparison is made between the power supply voltage value V and the inoperable state level L2 (S204), and if the power supply voltage value V is greater than the inoperable state level L2 (L1> L2) A battery warning is displayed (S205). Subsequently, the system control unit 50 performs access processing (S207) and ends the processing procedure of FIG.

To do. Subsequently, the access processing to the recording medium 200 is continued, and the processing procedure of FIG. 2 is ended (S207 → S208). Finally, when the processing procedure of FIG. 2 is completed (S208), the system is shut down, and “Lb” is displayed on the other display unit 54 to indicate that the operation is not possible due to the power supply voltage drop, and the operation is notified to the user. To do. The values of L1 and L2 are determined in advance and are defined in the program.

  Note that the power control according to the present invention is related to writing of data during file access of the reproduction processing apparatus, and is not limited to the generation of a print designation file. For example, even in a voltage state where the processing cannot be continued during execution of all image deletion in the recording units 200 to 201, the processing can be continued by turning off the backlight of the image display unit 28. At this time, an LED or the like can be substituted to indicate that processing is in progress. Similarly, the recording medium initialization process and the like can also be realized by using the present invention.

  In any case, when the instruction from the operation unit or the specific control process is executed, the process of FIG. 2 is executed. In this case, the execution of the access process in FIG. 2 is executed by the system control unit 50 by a process instructed by the operation unit or a control process instructed by another program of the system control unit 50.

  The above-described print designation process will be described with reference to FIGS. FIG. 3 is a block diagram showing processing contents of print designation. FIG. 4 shows an image selection screen for print designation. FIG. 5 is a flowchart showing the contents of a program for executing the detection and analysis flow of the print designation file existing in the recording units 200 to 201.

  When the user sets the mode dial 60 to “PLAY”, the playback mode is activated, and the system control unit 50 first analyzes the print designation file in the recording units 200 to 201.

  In order to check whether the print designation file exists, the system control unit 50 first searches a directory called MISC (directory name of the print designation file) on the root directory of the recording units 200 to 201 (S610 in FIG. 5).

  If the MISC does not exist, the analysis process is terminated because the print designation file does not exist (S609). Subsequently, the system control unit 50 determines whether the MISC is a file (S602). When the MISC is not a directory but a file, after graying out the print designation item in the reproduction menu M300 in FIG. 3 (S606), the processing procedure in FIG. 5 is terminated (S609).

  When the MISC is a directory (NO in S602), the AUTPRINT. It is determined whether a file called MRK exists (S611). If there is no such file, the processing procedure of FIG. 5 is terminated (S609).

  AUTPRINT. When the MRK exists, the system control unit 50 sets an EXIST flag indicating that the mark file exists (S612), and the AUTPRINT. The attribute of the MRK file is examined (S603). AUTPRINT. When the MRK has a read-only attribute (that is, write-inhibited attribute), the print designation item of the reproduction menu M300 is grayed out, and the processing procedure of FIG. 5 is ended (S603 → S606 → S609).

  The attribute indicates write permission, and AUTPRINT. If writing to the MRK is possible, the system control unit 50 checks the remaining storage capacity of the recording units 200 to 201 (S604). If there is not enough space to write one piece of print designation information, the system control unit 50 grays out the print designation item in the reproduction menu M300 and ends the process (S604 → S606 → S609).

  If there is a remaining amount, AUTPRINT. The MRK file is analyzed (S605). In the file analysis of S605, it is analyzed whether or not the syntax can be generated by this apparatus, and whether or not the print-designated image exists in the recording units 200 to 201, and both conditions are satisfied. If it is, it is determined that the file can be generated by the present apparatus (YES determination in S607).

  The file analysis result is set in a print type variable, an image information variable, a print designation number, and a standard print total number variable. Among the variables, the print type variable value and the image information variable value are set on the nonvolatile memory 56. If it is determined in step S607 that the image cannot be generated by the apparatus, a warning flag to be displayed on the print designation menu 301 is set (S607 → S608), and the processing procedure in FIG. 5 is terminated (S609).

  If it is determined that the file can be generated by this apparatus, the processing procedure of FIG. 5 is terminated as it is (S607 → S609). After completing the above analysis processing, the system control unit 50 reproduces an image existing in the recording units 200 to 201.

  When the user presses the menu button on the operation unit 70 during image reproduction, the reproduction menu M300 shown in FIG. In the playback menu, items are moved with the +/- buttons of the operation unit 70, and items are determined with the SET button.

  If the item grayout is set, this item is grayed out and cannot be selected from the menu. Further, when a warning flag is set in the processing of S608, a “!” Icon indicating a warning that information is rewritten is displayed. When the SET button is pressed in the print designation item, a print designation menu M301 (see FIG. 3) is displayed.

  When displaying the print designation menu M301, the system control unit 50 acquires the print type variable and the image information variable from the nonvolatile memory 56, and sets them in the menu print type M310 and image information M340. Further, the print designation number and the standard print total number variable are referred to and displayed next to the image designation M320 item.

  In the print designation menu M301, print type M310, image designation M320, designation cancellation M330, and image information M340 are selectable items. When the SET button is pressed with the print type M310, the standard M311, index M312 and both M313 can be selected, and any item is selected with the SET button.

  If the MENU button is pressed at this time, the selection is canceled and the print designation menu M301 is restored. Here, both M313 means that both standard and index print designation is performed. This set value is set in the nonvolatile memory 56.

  When the user selects the image designation M320, either the selected image M321 or the entire image M322 can be selected. When the selection image M322 is selected, the mode shifts to the marking mode shown in FIG. When the user selects all images M323, print designation of all images recorded in the recording units 200 to 201 is performed.

  At this time, if the number of sheets is limited due to restrictions on the print designation syntax, the system control unit 50 designates the number of sheets including the latest image, and displays a “!” Icon next to the print number display. In addition, when it is not possible to designate printing of all images in the recording units 200 to 201 due to restrictions on the remaining CF capacity, the system control unit 50 displays an “!” Icon next to the number display and a “CF card is full” display.

  In M310 of FIG. 3, when the index print and both are selected, an index job S730 is described. Similar to the standard job, the index job 730 starts with a tag S730 that declares a job. S731 is a tag indicating the printing order. S732 is a tag indicating the print type. S733 indicates the file format of the print image.

  S735 is a print setting, in which the file path of the image designated in the designation step and setting information based on the designation of S734 and M341 in FIG. 3 are described. If only single image information printing is permitted at the time of index printing, and if both are selected in M341 in FIG. 3, one of them is described as S735.

  In this embodiment, the file number is given as a description example. When there are a plurality of images designated by the index, if the next image format is different from the format of the previous image, the process starts from S733. If the previous image and the next image match, the process proceeds to S734. Describe from. In this way, the system control unit 50 describes the index job for the designated number of images in the print designation file in the recording medium 200/210, and ends the creation of the index job description S705.

  The print designation information set according to the designation method is updated at the following timing.

  (1) When the MENU key is pressed in the print designation menu. At this time, “processing ...” and a progress bar are displayed at the bottom of the menu, and the display returns to the playback menu after completion.

  (2) When the dial is moved. At this time, as in (1), “processing in progress” and a progress bar are displayed, and the operation of the dial position is started after completion.

  (3) When lid opening occurs. At this time, as in (1) and (2), “processing in progress” and a progress bar are displayed, and a warning is given by a buzzer.

  (4) During auto shutdown, “Processing ...” and progress bar are displayed as in (1), and the system is shut down after updating.

  (5) When an image designated for printing is deleted. However, if the Revision ID in the print designation file is evaluated and is different from the ID generated by the camera, it is not edited. The editing part is the [HDR] section, the standard job section including the erased image, and the corresponding line in the index job.

  (6) When Lb occurs. At this time, the LCD backlight is turned off, a warning is given by a buzzer, the file is updated, and then the system is shut down.

  In any case, while the file is being updated, the disk access status is notified by LED blinking display.

  As can be easily understood from the above description, according to the present embodiment, when the power supply voltage drop is detected during file access in the image playback mode and the process becomes impossible to execute, the power of the image display device is turned off. The process can be completed by dropping (shutdown).

  It should be noted that the present invention includes an apparatus in which the power consumption of the display device is reduced because the processing is completed without turning off the power. For example, the display brightness of the display device may be reduced or the display area may be reduced. Further, even if the power supply voltage is not detected in order to detect the power supply capability, another method, for example, a current may be detected, or the supply capability may be estimated from the usage history.

  In addition to the above embodiment, the following embodiment can be implemented.

  In the above-described embodiment, an image processing apparatus such as a digital camera has been described. However, the present invention can be applied to various information processing apparatuses that handle battery-driven images.
