If the mode switch 41 is set to any one of the ISO value, the custom function, and the rewind mode, the same process as the process of changing the normal mode or the like is performed. Execute and return (S217, S
219-S235).

When the mode switch 41 is set to any one of the exposure mode, drive mode, strobe mode, and electronic sound mode, the mode in each mode is changed and a process of rewriting the mode written in the memory 166 is executed. Run.

In the rewriting process, the TV operation dial 92
When the TV operation dial 92 is rotated, the mode set by the mode switch 41 is displayed on the liquid crystal display panel 21 (S217 to S217).
223, S241, S243).

Next, it is checked whether or not the memory switch 71 is on. If it is not on, S219
Return to (S245, S219). Therefore, when the mode switch 41 is set to the exposure mode,
Steps S219, S221, S223, S225, S
229, returns through S233, and repeats the above processing when called again by a timer interrupt or another subroutine, and waits for the memory switch 71 to turn on in the drive mode, strobe mode, or electronic sound mode. In the meantime, each mode can be selected.

When the memory switch 71 is turned on, all the stored contents of the memory 166 relating to the corresponding mode are cleared, the mode display of the liquid crystal display panel 21 is made to blink, and the memory switch 71 is turned on again, that is, once turned off. Wait until it is turned on again (S245, S24
7, S249).

When the memory switch 71 is turned on again, all the change / selection modes displayed on the liquid crystal display panel 21 are stored in the memory 166, and the liquid crystal display panel 21 is stored.
Flashes and turns on (S251, S25
3, S255). Through the above processing, only the newly selected mode is stored in the memory 166. In addition, the photographer can surely know that the mode / function is newly stored in the memory 166 by the process of lighting → blinking → lighting of the liquid crystal display panel 21.

As described above, according to the present embodiment, the RAM 1 for storing the mode / function used for normal display and photographing.
Instead of storing all the modes / functions stored in RAM 162 in a memory 166 separate from 62, only the changed modes / functions are stored in memory 16 at any time during the mode / function selection process.
6 can be rewritten. Therefore, the user
Select and change only the mode / function you want to change,
By pressing the ML button 122, only that mode / function can be stored. And RAM16
Among the modes / functions stored in memory 2 and normally used, the modes / functions stored in the memory 166 can be used for shooting.

In this embodiment, the selected mode / function is stored in the storage means 166 during the selection process of the mode / function, and the storage of the mode / function and the end of the storage process are blinking and lighting. Although the second display mode is used to notify the photographer, the present invention is not limited to this structure.

[0063]

As is apparent from the above description, according to the present invention, one or more desired modes / functions among a plurality of normally used modes / functions are separately stored, and when desired. Since the separately stored modes / functions can be called and used in place of the corresponding normal mode / function,
Operations such as mode / function switching and correction become easy.
