A character "●" indicating that the first digit ID has been input is displayed on the screen as shown in FIG.

Next, the second digit ID code conversion screen by key input is displayed (step S2), and when the operator inputs the "MODE" key 13, for example, the CPU 3
1 is an ID key code table 28A in the ROM 28
From, the ID key code "04H" corresponding to the "MODE" key 13 "is read out and stored as 1-byte information in the register in the CPU 31, and the LCD 6
A character "●●" indicating that the second digit ID has been input is displayed on the screen as shown in FIG.

Subsequently, the ID of the third digit by key input
A code conversion screen is displayed (step S3), and when the operator inputs the "DSP" key 14, for example, C
The PU 31 reads the ID key code "05H" corresponding to the "DSP key 14" from the ID key code table 28A in the ROM 28 and stores it as 1-byte information in the register in the CPU 31. LC
At D6, a character "●●●" indicating that the third digit ID is input is displayed as shown in FIG.

Then, the CPU 31 causes the ID key code "03" of the 3-byte information stored in the internal register.
H "," 04H ", and" 05H "are set as IDs and stored (registered) in a predetermined area of the flash memory 27 (step S4), and the ID setting process is completed.
In the setting process, the operation procedure of multiple function keys "" D
"EL" key 10 → "MODE" key 13 → "DSP" key 14 "indicating an ID key code" 03H, 04H, 0 "

When the operator operates the function keys of the key input section 30 to input the ID (step S
14), it is determined whether the input ID and the ID registered in the flash memory 27 match (step S15). If the IDs match, step S1
Then, the process proceeds to step 6 and the above-mentioned main process is executed.

On the other hand, if the IDs do not match in step S15, an error message indicating that the IDs do not match is displayed on the LCD 6 (step S17), the process proceeds to step S13 again, and the same routine is repeated unless the IDs match. Specifically, the ID registered in the above ID setting process (FIG. 4)
It is determined whether or not "03H, 04H, 05H" and the ID corresponding to the operation procedure of the input function key match. At that time, the function key is "DEL" key 10 →
When the "MODE" key 13 and the "DSP" key 14 "are input in this order, the ID is" 03H, 04H, 0 ".
5H "is input, so it is determined that the registration ID and the input ID match. On the other hand, for example, the function key is""MOD
"E" key 13 → "DEL" key 10 → "DSP" key 1
When input in the order of "4", the ID is "04H,
03H, 05H ”is input, and it is determined that the registered ID and the input ID do not match. That is, if the input operation procedure of the function key matches the operation procedure of the registered function key, the ID Are determined to match, and even if the types of function keys to be input match, if the operation procedures are different, it is determined that the IDs do not match.

In the above-described ID collation processing, when the ID corresponding to the registered operation procedure of the key input unit 30 and the ID input by operating the function key of the key input unit 30 match, As the main processing, for example, L of the image corresponding to the image data stored in the flash memory 27 is used.
Since the structure is such that it can be displayed (reproduced) on the CD 6, it is possible to register and register the ID only by operating the keys for operating the functions of the digital camera without providing a numeric keypad for inputting data such as numbers and alphabets Matching is possible.
As a result, it is possible to provide a low-cost and space-saving digital camera having an ID collating function.

In the above embodiment, the ID display is fixed to a specific character "●", but the present invention is not limited to this. For example, each ID key The ID may be recognized by the user as a number by displaying the number assigned as the code.

In the above embodiment, when the IDs match, the flash memory 27 is used as the main process.
Although an example is shown in which the image data stored in (1) can be displayed (reproduced) on the LCD 6, the main processing of the present invention is not limited to this. For example, when the IDs match,
The flash memory 27 may store the image of the subject. In short, in the digital camera, when the registered ID and the input ID match, reproduction or recording processing of the digital camera body can be performed.
