  Next, the operation of the image display system 100 of the present embodiment will be described with reference to FIG. FIG. 4 shows a flow of the first image data transmission process executed by the PC 30 and the first image data display process executed by the digital camera 10.

  First, the first image data transmission process executed by the PC 30 will be described. The first image data transmission process is a process of transmitting image data to be displayed on the digital camera 10 as a slide show to the digital camera 10. It is assumed that image data for displaying a slide show is stored in the storage unit 35 in advance.

  For example, when a slide show display instruction is input from the user via the operation unit 32 as a trigger, the CPU 31 appropriately reads out the first image data transmission program from the storage unit 35 and expands it in the RAM 33. The first image data transmission process is executed in cooperation with the first image data transmission program and the CPU 31.

  First, based on the presence / absence of an input instruction such as a slide show setting via the operation unit 32, it is determined whether or not to execute various slide show settings and selection of at least one image data for slide show display ( Step S11). Examples of various slide show settings include, for example, image data display switching intervals, image data expression methods (appearing from the center of the screen, fading out, etc.), loop settings, and the like.

  When a slide show setting or the like is input (step S11; YES), various slide show setting inputs are accepted via the operation unit 32, and further, a slide show display image data selection input is accepted (step S12). Then, information indicating that the slide show is to be requested and various setting information of the slide show are transmitted to the digital camera 10 via the I / F unit 37 and the cradle 20 (step S13). The various setting information is the setting information input in step S12.

  In order to use default setting information and image data, when no slide show setting or the like is input (step S11; NO), the process proceeds to step S13. In this case, default setting information is transmitted in step S13.

  Then, the display image data or default image data is optimized for display on the digital camera 10 (step S14). Optimization is, for example, when the selected image data is in the bitmap format, converted to JPEG format, or the number of pixels of the selected image data is reduced to one corresponding to the resolution of the display unit 14. . The image data having the optimized format and size is set as optimized image data.

  Then, it is determined whether there is unselected optimized image data that has not been selected in step S16, which will be described later (step S15). If there is unselected optimized image data (step S15; YES), one unselected optimized image data is selected (step S16). This selection order is the display order in the slide show.

  Then, the optimized image data selected in step S16 is transmitted to the digital camera 10 via the I / F unit 37 and the cradle 20 (step S17), and the process proceeds to step S15. If there is no unselected optimized image data (step S15; NO), the fact that the transmission of the image data has been completed is transmitted to the digital camera 10 via the I / F unit 37 and the cradle 20 (step S18). The image data transmission process ends.

  Next, a first image data display process executed by the digital camera 10 will be described. The first image data display process is a process of displaying the image data received from the PC 30 on the display unit 14 as a slide show.

  Corresponding to step S13, the control unit 20 receives the first image data from the ROM as a trigger when the slideshow request information and various setting information are received from the PC 30 via the cradle 20 and the I / F unit 18. The display program is appropriately read out and expanded in the RAM, and the first image data display process in the RAM and the first image data display process are executed in cooperation with the CPU.

  First, the mode to be executed is switched to a slide show mode for displaying a slide show, and various settings are executed based on the received various setting information (step S21). Then, in response to step S17, it is determined whether or not image data (optimized image data) starts to be received from the PC 30 via the cradle 20 and the I / F unit 18 (step S22). When image data reception is started (step S22; YES), the image data is received (step S23).

  The received image data is displayed as a slide show on the display unit 14 based on the received various setting information (step S24). If the image data has not started to be received (step S22; NO), the process returns to step S22, but if the image data has not started to be received even after a predetermined time has elapsed, this process ends as an error (not shown).

  Then, in response to step S18, it is determined whether or not the transmission end has been received from the PC 30 via the cradle 20 and the I / F unit 18 (step S25). If the end of image data transmission is not received (step S25; NO), the process proceeds to step S22. When the end of transmission is received (step S25; YES), the first image data display process ends. At this time, for example, when a slide show loop is set, a slide show is displayed in a loop on the display unit 14, and when a slide show end instruction is input from the operation unit 13, the first image data display process is performed. finish.

  As described above, according to the present embodiment, image data is transmitted from the PC 30 to the digital camera 10 placed on the cradle 20, and the image data is received by the digital camera 10 and displayed on the display unit 14. Even when it is not, the image data of the PC 30 can be displayed by effectively utilizing the display unit 14 of the digital camera 10.

  Further, since the image data is optimized on the PC 30 side so as to correspond to the digital camera 10 and transmitted to the digital camera 10, the image data can be displayed optimally on the digital camera 10, and the digital camera 10 A means for optimizing the image data is not required, the device configuration of the digital camera 10 can be simplified, the manufacturing cost and size can be reduced, and the communication amount (communication time) can be reduced.

  In the present embodiment, the digital camera 10 is configured to display a plurality of image data as a slide show. However, the present invention is not limited to this. For example, a configuration may be adopted in which image data for other display such as normal display is transmitted from the PC 30 to the digital camera 10 and the digital camera 10 displays the image data.

  Further, for example, when a plurality of image data is displayed on the digital camera 10, the display image of the digital camera 10 may be switched by an image switching input via the operation unit 13 or 32. For example, the image editing application program is executed on the PC 10, the image data being edited is displayed on the display unit 34 in real time, the image data before editing is transmitted from the PC 30 to the digital camera 10, and the image before editing is processed by the digital camera 10. A configuration in which data is appropriately switched by switching input and displayed, and the edited image data displayed on the display unit 34 and the image data before editing displayed on the digital camera 10 can be easily compared by the user. Good.

  The image data displayed on the digital camera 10 may be stored in the memory card 151 or the flash memory 17 by user selection, or may be automatically recorded. In this configuration, even when the digital camera 10 is removed from the cradle, the image data received from the PC 30 stored in the memory card 151 or the flash memory 17 can be read and displayed on the display unit 14.

(Second Embodiment)
A second embodiment according to the present invention will be described with reference to FIGS. The apparatus configuration of the present embodiment is the same as that of the first embodiment, and a description thereof will be omitted.

  With reference to FIGS. 5 and 6, the operation of the image display system 100 of the present embodiment will be described. FIG. 5 shows a flow of the second image data transmission process executed by the PC 30 and the second image data display process executed by the digital camera 10. FIG. 6A shows a display screen example of the PC 30 in this embodiment. FIG. 6B shows an example of a display screen of the digital camera 10 in the present embodiment.

  First, the second image data transmission process executed by the PC 30 will be described. The second image data transmission process is a process of transmitting image data of sticky notes (sticky note image data) to the digital camera 10. It is assumed that a word processor program is executed in advance on the PC 30 and the document data is edited by the user. Here, the program being executed is not limited to the word processor program, but may be another application program or the like as long as the tag data can be pasted on the editing data. The sticky note data is non-image data that is not image data in JPEG format or bitmap format.

  For example, the CPU 31, the RAM 33, and the storage unit 35 can use the second image by the CPU 31, the RAM 33, and the storage unit 35 as triggered by the input of a sticky note extraction display instruction from the user via the operation unit 32. Data transmission processing is executed.

  First, information indicating that execution of sticky note data extraction display is requested is transmitted to the digital camera 10 via the I / F unit 37 and the cradle 20 (step S31). Then, it is determined whether or not the editing operation of the active application program has been completed (step S32). During this editing operation, the user inputs additional / deleted sticky note data via the operation unit 32 at any time.

  If the editing operation of the activated application program has not been completed (step S32; NO), it is determined whether or not new input of sticky note data has been performed by the user via the operation unit 32 (step S32). S33). Here, the new input of the sticky note data is an addition input and deletion input of the character of the sticky note data, and when it passes through step S33 for the first time (the sticky note data included in the already opened editing data). For the first time input).

  When new input of sticky note data is performed (step S33; YES), the newly input sticky note data is extracted from the editing data and converted into JPEG format image data (referred to as sticky note image data). (Step S34). The sticky note image data converted in step S33 is transmitted to the digital camera 10 via the I / F unit 37 and the cradle 20 (step S35), and the process proceeds to step S32. If new input of sticky note data has not been performed (step S33; NO), the process proceeds to step S32.

  When the editing operation of the active application program is completed (step S32; YES), the fact that image data transmission is completed is transmitted to the digital camera 10 via the I / F unit 37 and the cradle 20 (step S36). The second image data transmission process ends.

  Next, the second image data display process executed by the digital camera 10 will be described. The second image data display process is a process of displaying a list of image data of sticky notes received from the PC 30 on the display unit 14.

  Corresponding to step S31, the control unit 20 uses the second image data display processing in the control unit 20 triggered by the fact that the request information for the sticky note data extraction display is received from the PC 30 via the cradle 20 and the I / F unit 18. Is executed.

  First, the mode to be executed is switched to a sticky note display mode for displaying sticky note data (step S41). Then, in response to step S35, it is determined whether or not the sticky note image data starts to be received from the PC 30 via the cradle 20 and the I / F unit 18 (step S42). If the sticky note image data is not started to be received (step S42; NO), the process returns to step S42, but if the sticky note image data is not started to be received after a lapse of a predetermined time, this process is terminated as an error ( (Not shown). When reception of the sticky note image data is started (step S42; YES), the sticky note image data is received (step S43).

  Then, based on the received sticky note image data, the image data being stored in the DRAM 16 and being displayed on the display unit 14 (display image data) is updated to the latest state in which sticky notes are arranged. Display image data is displayed on the display unit 14 (step S44). When step S44 is executed for the first time, display image data is created based on the received sticky note image data and stored in the DRAM.

  Corresponding to step S35, it is determined whether or not the transmission end is received from the PC 30 via the cradle 20 and the I / F unit 18 (step S45). If the end of image data transmission is not received (step S45; NO), the process proceeds to step S42.

  When the end of transmission of the image data is received (step S45; YES), it is determined whether or not there is an instruction input for saving the display image data stored in the DRAM 16 via the operation unit 13 by the user. (Step S46). It is determined whether or not there is an instruction input for saving the display image data (step S46). When there is an instruction input to save the display image data (step S46; YES), the display image data is read from the DRAM 16 and stored in the memory card 151 by the information recording unit 15 (step S47), and the second image data display is performed. The process ends. The display image data may be stored in the flash memory 17 instead of the memory card 151. If there is no instruction input to save the display image data (step S46; NO), the second image data display process is terminated.

  For example, as shown in FIG. 6A, when the display screen 34a is displayed on the display unit 34 on the PC 30, the word processor document is edited by the user, and the sticky note data P1 and P2 are input. As shown in FIG. 6B, in the digital camera 10, the display screen 14a including only the sticky note data P1 and P2 is displayed on the display unit 14 in real time. For this reason, it is easy to refer to the sticky note in the document editing of the word processor, and the PC 30 makes it easy for the user to scroll to the sticky note portion or move the cursor.

  As described above, according to the present embodiment, in the PC 30, the sticky note data is extracted from the editing data of the application program and converted into image data, and the sticky note image data from the PC 30 is converted into the digital camera 10 placed on the cradle 20. And the sticky note image data is received by the digital camera 10 and displayed on the display unit 14. Therefore, the display unit 14 of the digital camera 10 is effectively used to display the image data of the PC 30, and the editing data is being edited. The predetermined data (sticky note data) can be extracted and displayed.

  In the present embodiment, the sticky note data input from the PC 30 is displayed in real time on the digital camera 10, but the present invention is not limited to this. For example, a configuration may be adopted in which a predetermined number (one or more) of sticky note data is input and transmitted from the PC 30 to the digital camera 10 in order. Moreover, it is good also as a structure which transmits and displays to the digital camera 10 collectively from PC30 at the timing when all the sticky note data is input.

  Further, in the present embodiment, the sticky note data as non-image data input by the PC 30 is converted into optimal image data and displayed by the digital camera 10, but other character data, table data, Non-image data that can be converted into image data such as mathematical formula data may be converted by the PC 30 and displayed on the digital camera 10. Further, if the digital camera is configured to be able to directly display character data or the like, the image data may be configured not to be converted by the PC 30. Also in the first embodiment, the PC 30 may be configured to convert data other than image data into image data that is optimal for the digital camera 10.

(Third embodiment)
A third embodiment according to the present invention will be described with reference to FIGS. The apparatus configuration of the present embodiment is the same as that of the first embodiment, and a description thereof will be omitted.

  The operation of the image display system 100 according to the present embodiment will be described with reference to FIGS. FIG. 7 shows a flow of a third image data transmission process executed by the PC 30 and a third image data display process executed by the digital camera 10. FIG. 8 shows the configuration of the identification number correspondence table 331. 9A, 9C, and 9E show examples of display screens of the PC 30 in the present embodiment. FIGS. 9B, 9D, and 9F show examples of display screens of the digital camera 10 in the present embodiment.

  First, the third image data transmission process executed by the PC 30 will be described. In the third image data transmission process, image data for position search (key image data) is transmitted to the digital camera 10 and the display position of the edit data of the application program is transmitted from the digital camera 10. This is a process of moving to a position corresponding to the identification number. It is assumed that a word processor program is executed in advance in the PC 30 and document data is opened and displayed on the display unit 34 by a user operation. Here, the program being executed is not limited to the word processor program, and any other application can be used as long as the image data can be pasted on the editing data, such as a spreadsheet program or a presentation data creation program. It may be a program or the like.

  For example, in the same manner as in the first embodiment, the CPU 31, the RAM 33, and the storage unit 35 are triggered by the input of an image search instruction for searching using image data as a key from the user via the operation unit 32. The third image data transmission process is executed.

  First, information indicating that display screen movement is requested by image selection is transmitted to the digital camera 10 via the cradle 20 and the I / F unit 37 (step S51). All image data in editing data such as opened document data is acquired together with position information in the editing data, and an identification number is assigned to each image data, and stored in the RAM 33 in association with each position information. (Step S52). For example, as shown in FIG. 8, an identification number correspondence table 331 in which the identification number 3311 of each image data is associated with the position information 3312 is created and stored in the RAM 33.

  Then, the image data acquired in step S52 is optimized for display on the digital camera 10 (step S53). Then, the optimized image data and the identification number thereof are associated with each other and transmitted to the digital camera 10 via the I / F unit 37 and the cradle 20 (step S54).
