The first input signal corresponds to an initial input of the shutter release button or an input signal of the first button 331 of FIG. 3. The second button input unit 516 receives a second input signal according to the shutter release button. The second input signal corresponds to a second input of the shutter release button or an input signal of the second button 332 of FIG. 3.

When the first input signal is input, the microcontroller 512 processes the input to control the photographing preparation operation such as auto focusing. When the second input signal is input, the microcontroller 512 processes the input to control the photographing operation to be performed.

The digital image signal from the digital signal processor 507 is temporarily stored in the DRAM (Dynamic Random Access Memory) 504. The EEPROM (Electrically Erasable and Programmable Read Only Memory) 505 stores algorithms and setting data such as a boot program and a key input program required for the operation of the digital signal processor 507. In the memory card interface 506, a user's memory card is detached.

The digital image signal from the digital signal processor 507 is input to the display panel driver 514, whereby the image is displayed on the display panel 25.

On the other hand, the digital image signal from the digital signal processor 507 can be transmitted by serial communication via the USB (Universal Serial Bus) connection 31a or the RS232C interface 508 and its connection 31b, and the video filter ( 509 and video output 31c may be transmitted as a video signal. Here, the digital signal processor 507 may have a microcontroller therein.
