Here, FIG. 2 shows an example of connection via the connection cable 20 using USB (Universal Serial Bus) or the like, but a wireless connection method such as IrDA (Infrared Data Association) may be used.
[0026]
FIG. 3 is a flowchart showing the operation of the digital camera represented by the block diagram of FIG. In FIG. 3, first, in step S101, the digital camera 1 detects that the peripheral device 2 is connected. In step S102, it is detected that the application program has been started on the peripheral device 2, and an applet program related to the program is read from the peripheral device 2 in step S103. If the digital camera 1 and the peripheral device 2 are connected after the application is started in the peripheral device 2, the digital camera 1 reads an applet program related to the active application program at the time of connection.
[0027]
In step S104, an image file to be output to the peripheral device 2 is selected.

Output to.
[0028]
FIG. 4 illustrates a case where a printer is further connected as the peripheral device 2 in FIG. The peripheral device 2 includes a printing unit 205 that prints image data. Here, the above-described application program refers to a program for operating a printer and performing print output. The unique information storage unit also includes color matching information for correcting the printing characteristics of the printing unit and maximum resolution information of the printer. The operation of FIG. 4 will be described based on the flowchart of FIG. First, in step S201 in FIG. 5, it is determined whether or not a printer is connected to the digital camera 1 as the peripheral device 2. If not connected, a normal recording process is performed on the photographed image in step S202. That is, after the subject is photographed by the imaging unit 101, normal gamma adjustment, white balance, and the like are performed, and then compression is performed as necessary, and the result is recorded in the memory card 104 in step S203.

It is desirable to set recording on the memory card in step S206 from the standpoint of leaving the photographed image. For example, a camera and a printer are installed on the street, and a large number of unspecified subjects are photographed and printed. For such business use, there is no need to leave a photographed image. In such a case, it is more appropriate to set not to record in the memory card.
[0031]
FIG. 6 shows a case where the digital camera and printer described in FIG. 4 are integrated. In this case, only one of the unique information storage units 110 and 203 in FIGS. 1 and 4 may be provided. The interface units 109 and 201 only need to have appropriate internal communication means. These are not limited to a printer-integrated digital camera, and the same applies to a configuration in which a digital camera and peripheral devices are integrated, such as a game machine or a personal computer having an image capturing unit.
[0032]
FIG. 7 is a block diagram of a second embodiment according to the present invention. As shown in FIG. 1, the digital camera 3 includes an imaging unit 101, a recording / playback unit 102, a buffer 103, operation buttons 106, a display unit 107, a CPU 108, and an interface unit 109. Furthermore, an applet program including unique information corresponding to a plurality of types of peripheral devices 4 connectable to the digital camera 3 is stored in the unique information storage unit 301. Here, the peripheral device refers to a printer, a monitor, a mobile phone, and the like, and also corresponds to the case where, for example, the models are different among the same type of devices.
[0033]
The specific information is transmitted to the digital camera 3 such information as the number of pixels, the maximum resolution, the number of display colors, the color matching information, the maximum resolution information of the printer, the gamma characteristic of the monitor, etc. An applet program for processing image data based on the information. The operation button 106 selects an image from the image data storage unit 304 or selects a necessary applet program from the unique information storage unit 301. The applet program is also selected by the unique information selecting unit 302 from the unique information recording unit 301 based on the identification result of the peripheral device identifying unit 305 described later.
[0034]
The processing means 303 performs a predetermined process on these selected images based on the selected applet program. The processed image data is stored in the image data storage unit 304. At this time, the management unit 310 manages the selected image and the processed image in association with each other. When a peripheral device is connected to the digital camera 3, the peripheral device identification means 305 identifies the manufacturer name, product name, product number, etc. of the peripheral device and also identifies the applet program name corresponding to the peripheral device. Based on the identification result, the unique information selection unit 302 selects the same applet program from the unique information storage unit 301.
[0035]
If the same applet program is not stored or if an old applet program is stored, a new applet program is obtained from the peripheral device 4 and stored in the specific information storage unit 301. When a plurality of peripheral devices are connected to the digital camera 3 at the same time, optimum processed image data is output for each peripheral device based on the identification result of the peripheral device identifying means 305.
[0036]
The unique information storage unit 301 and the image data storage unit 304 are in a common data storage area 306, and the specific information and the image data are designated by the CPU 108 for each recording area. This common data storage area refers to, for example, a recording area for image and audio data in a memory card. The image data storage unit 304 stores both the image data that has been subjected to normal recording processing by the recording / reproducing unit 102 and the image data that has been processed according to the specific information by the processing unit 303. The remaining capacity of the common recording area is displayed on the LCD monitor 107 as display means.
[0037]
The applet program name identified by the peripheral device identifying means 305 and the applet program selected by the specific information selecting means 302 are compared by the comparing means 307 to see if they match. If they do not match, the voice warning means 308 gives a warning. The erasing unit 309 erases unnecessary data in the data storage area 306. The peripheral device 4 includes an interface unit 401 and a specific information storage unit 402 for storing an applet program including specific information related to the peripheral device.
[0038]
8 to 14 are a flowchart showing an example of the operation of the digital camera shown in FIG. 7 and an example of a monitor display. First, in step S401 in FIG. 8, the operation button 106 is operated to display the applet program name stored in the unique information storage unit 301 in the memory card on the LCD monitor 107, and the desired applet program is selected therefrom. Similarly, in step S402, an image is read from the image data storage unit 304 in the memory card, displayed on the LCD monitor 107, and an image to be output from the digital camera 3 is selected. Thereafter, in step S403, predetermined processing is performed so as to adapt to the output device based on the selected applet program.
[0039]
In step 404, the management unit 310 associates the selected image with the processed image in accordance with an instruction from the CPU 108, and the processed data in step S405 is stored in the buffer 103 or the image data storage unit 304 in the memory card. If it is desired to output to a plurality of types of peripheral devices at the same time, a plurality of applet programs corresponding to the plurality of peripheral devices are selected, images processed by these applet programs are stored in the image data storage unit 304, and a plurality of selected images and a plurality of images are selected. The processed image data corresponding to the peripheral device is associated.
[0040]
This association will be described with reference to FIG. FIG. 9 shows an example of image reproduction on the LCD monitor 107. Here, the image content and the image file name are simultaneously displayed in a quarter size of the screen. When an image is selected by operating the operation button 106 from here, the image data processed for normal storage stored in the image data storage unit is selected according to the specific information previously selected in step S401 in FIG. Processing is performed. In this way, the management unit 310 associates the image or image file name displayed on the LCD monitor 107 with the processed image. Of course, the displayed image or image file name and the image before processing of the image data portion are also associated with each other. If there are processed images corresponding to a plurality of output devices, the processed images are further associated with each other. In this way, for example, when a printer and an external monitor are connected to the digital camera at the same time and an image or image file name displayed on the external monitor is selected, the processing is managed in association with the printer from the printer. Prints based on image data can be output.
[0041]
The processed image data associated in this way is stored by the CPU 108 in the buffer 103 or the image data storage unit 304 in the memory card. In step S406, it is determined whether or not all of the image data to be processed has been completed. If not, the process returns to step S401 to repeat the processing so far. This process is similarly repeated when a plurality of pieces of unique information are selected. In this way, a plurality of pieces of image data processed corresponding to a plurality of pieces of unique information are stored in the digital camera 3 after a predetermined association. The timing of this association is not limited to the example described here, and the management unit 310 can easily associate with a processed image at any point in time or cancel the association.
[0042]
FIG. 10 shows a flow when a peripheral device is connected after a plurality of pieces of image data processed in advance by the digital camera 3 based on the procedure of FIG. 8 are stored in the buffer 103 or the image data storage unit 304 in the memory card. Show. In FIG. 10, when the digital camera is turned on, the number of remaining frames in the memory card is displayed on the LCD monitor 107 in step S501. FIG. 11 shows an example of the remaining frame display. In FIG. 11, the number of 100 frames is the remaining number of recordable frames excluding the area where the applet program or processed image data in the memory card is stored, and the number 105 in () is currently stored in the data storage area. This represents the remaining number of frames that can be stored when all the applet programs or processed image data are deleted.
[0043]
Details of the remaining frame display step S501 will be described first with reference to FIGS. In FIG. 12, when the number of remaining frames is reduced to 10 frames in step S5011, for example, the process proceeds to step S5012 to display on the LCD monitor 107 whether the applet program or the processed image is recorded in the memory card. If no applet program or processed image has been recorded, only the normal image is recorded, so in the next step S5013, a warning display (not shown) indicating that there are few remaining frames is displayed on the LCD 107, and the process ends. .
[0044]
If several applet programs or processed images are stored, whether or not they can be deleted is displayed on the LCD monitor 107 in the next step S5014 as shown in FIG. If it cannot be erased, the process advances to step S5013, and a warning display indicating that there are few remaining frames is displayed as in the previous step, and the process ends. If there is data that can be erased, the process advances to step S5015 to select erase data using the operation button 106. In the display example of FIG. 13, four types of applet programs are currently stored in the unique information storage unit 301, and the image data storage unit has been processed using two types of applet programs among these four types of applet programs. Indicates that an image is stored. Further, as shown in FIG. 13, three types of applet programs are checked for erasing.
[0045]
Thereafter, when YES is selected, the selected data is deleted in step S5016, and the process returns to step S5011. If the remaining capacity is sufficient in step S5011, the display shown in FIG. 11 is displayed in step S5017. In FIG. 13, the applet and the processed image data are dealt with as an integral deletion, but the applet and the processed image data may be selected separately. Further, processed image data may be selected on a screen-by-screen basis.
[0046]
When the remaining frame display and the remaining frame processing are completed in this way, the peripheral device type connected by the peripheral device identifying means 305 is identified in step S502 of FIG. In step S503, a specific applet program is selected by the specific information selection unit 302 based on the identification result of the peripheral device identification unit 305 and displayed on the LCD monitor 107.
[0047]
FIG. 14 shows an example of the monitor display. In the example of FIG. 14, the peripheral device identification unit 305 is a printer manufactured by company A connected to the digital camera 3, the model name is XYZ, and the version of the applet stored in this printer is Ver. It shows that it identified as 3.0. On the other hand, the unique information selecting means 302 is used as an applet program closest to the identified device from the unique information storage unit 301 to the A company printer, model name XYZ, Ver. This indicates that an applet program of 2.0 has been selected. In this case, a printer manufactured by company A that matches the model name but has an older version is stored. In such a case, it is effective to call attention with a sound warning means 308 such as a buzzer.
[0048]
In step S504, the user determines whether this selection is correct. If it is determined that there is no problem even if the versions are different and YES is selected, the processed image data is selected in step S505, and is output from the interface 109 in step S506. If there is no processed image, a processed image is created in the steps shown in FIG.
[0049]
If NO is selected in FIG. 14, the process proceeds to step S507, where a display for selecting another processing applet is displayed as shown in FIG. In the display example of FIG. 15, three options are shown. The first is a method of reading a new applet program from a connected peripheral device, the second is a method of processing with a predetermined applet program stored in advance in the digital camera 3, and the third is a method currently stored in the digital camera 3. It is a method of selecting and processing from the applet program. These are appropriately selected and executed, and the process returns to step S504. Even in this case, if there is no processed image, a processed image is created by the procedure described in FIG.
[0050]
Up to this point, the method of outputting image data that has been processed by the user in an appropriate manner based on the display result of the LCD monitor 107 has been described. Compared with the selection by the user based on this display, You may set so that the means 307 may perform automatically. Since the procedure after selecting the applet program is the same as the case where the user determines the treatment while viewing the display, the description thereof is omitted. At this time, the operation when the comparison result does not match is set in advance using the operation button 106.
[0051]
