[0050]
The operation of the digital camera 10 according to the present embodiment will be described.
[0051]
First, the operation of the digital camera 10 during shooting will be briefly described.
[0052]
A signal indicating the subject image output from the CCD 14 by imaging through the optical unit 13 is sequentially input to the CDS 16 and subjected to correlated double sampling processing, and then input to the ADC 18. The ADC 18 receives R ( The red, G (green), and B (blue) signals are converted into 12-bit R, G, and B signals (digital image data) and output to the image input controller 20.

Next, it is determined whether or not the external printer 110 issues a print instruction to the digital camera 10 (step 200). When a print instruction is issued to the digital camera 10 by the operation key 120, the printer type (inkjet printer, laser printer, etc.) and the manufacturer and model information of the printer are transmitted to the digital camera. An image is displayed (step 202). If no print instruction is issued in step 200, the process ends.
[0062]
It is determined whether or not the external printer 110 issues an image data editing instruction (step 204). When an instruction to edit image data is issued using the operation key 120, edit instruction information is transmitted to the digital camera 10.
[0063]
Subsequently, the external printer 110 sets the number of pixels for the print target image, and transmits the pixel number setting information to the digital camera 10 (step 208). The pixel number setting information refers to information for setting the number of pixels of the print target image to 6M, 3M, 1M, or the like. The image with the set number of pixels is subjected to image processing in the digital camera 10 and is displayed on the LCD 30 together with the data for the set number of pixels and the print target image subjected to image processing with the original number of pixels (step 206). The user sees a plurality of images of the set pixel number setting value displayed on the LCD 30 and temporarily selects an image having the desired pixel number by moving the cursor.

Next, an exposure correction value is set in the external printer 110 for the print target image, and exposure correction value information is transmitted to the digital camera 10 (step 210). The exposure correction value information refers to information for setting the exposure correction of the print target image to +1.0 EV, −1.0 EV, or the like. The set exposure correction image is subjected to image processing after gain adjustment in the digital camera 10, as shown in FIG. 6 together with the set exposure correction value data and the print target image image-processed with the original exposure correction value (0EV). It is displayed on the LCD 30 (step 206). The user looks at a plurality of images with the above-described set exposure correction value displayed on the LCD 30 and temporarily selects an image with his / her favorite exposure correction value by moving the cursor.
[0065]
Next, the print size is set in the external printer 110 for the print target image, and the print size information is transmitted to the digital camera 10 (step 212). The print size information is information such as A4, B5, and service size. The image of the set print size is subjected to image processing in the digital camera 10 and displayed on the LCD 30 together with the set print size data and the print target image subjected to image processing at the original print size (step 206). The user sees a plurality of images having the set print size displayed on the LCD 30 and temporarily selects an image having his / her favorite print size by moving the cursor.
[0066]
Although not shown in FIG. 5, a color balance value such as white balance is set by the external printer 110, and information on the color balance value is transmitted to the digital camera 10, and a plurality of color balance values set in various manners are transmitted. An image can be displayed on the LCD 30 and a desired image can be temporarily selected.
[0067]
When the user desires to print with the data of the temporarily selected images, the user operates the operation key 120 of the external printer 110 to determine the print target image (step 214). The information for determining the print target image is transmitted to the digital camera 10, and the image data of the determined image is stored (step 216). The determined image is displayed on the LCD 30 for several seconds (step 218). If there is a setting value to be changed, by operating the operation key 120 of the external printer 110, it is possible to return to steps 208, 210 and 212 to reset the setting value.
[0068]
The stored image data is output (step 220) and transmitted to the external printer 110. The processing of the digital camera 10 ends here. The external printer 110 determines whether printing is OK (step 222). If the print is not OK, the process returns to step 200. If image data editing is not performed in step 204, the process proceeds to step 222. When printing is performed by operating the operation key 120 in step 222, the CPU 114 of the external printer 110 drives the printing and mechanical driving means 122 to perform printing (step 224). When printing is performed, the processing of the external printer 110 ends.
