A process circuit for performing known image processing such as 5, a memory control unit (recording / reproducing unit) for compressing / decompressing image data and transferring signals from an external memory, and 6 for image expansion and camera control Memory to be used, 7 is an external memory for recording images, 8 is a memory for displaying images (buffer memory), 9 is a monitor display unit for displaying captured images, 11 is a camera operation switch, 12 is a system control composed of a CPU, etc. A circuit, 13 is a control device of an imaging optical system that performs exposure and distance measurement, and 14 is a photographing information display unit that displays a shutter speed, an aperture value, and the like.

  Next, the operation of the electronic camera having the above configuration will be described.

  First, the system control circuit 12 detects a change in the state of the camera operation switch 11 (configured by the camera main SW, release SW, operation buttons, etc.) by the photographer, and starts supplying power to the other circuit blocks. Then, the system control circuit determines the shutter speed, aperture value, and the like by the imaging optical system 1 and its control device 13 at regular intervals, and displays the information on the information display unit 14 for displaying the conditions for taking an image.

  Further, when the photographer performs a photographing operation by operating the camera operation switch 11, the imaging optical system 1 is activated by the control signal from the overall control circuit 12 and forms an image on the imaging element 2. The electrical signal from the image sensor 2 is converted into a predetermined digital signal through the A / D conversion circuit 3 in order for each pixel, and then input to the image processing circuit 4. The image processing circuit 4 generates RGB color signals based on the pixel data of the image sensor 2. Next, each pixel data is stored in the memory 6, and then the data in the frame memory 6 is compressed by the memory control unit 5 based on a predetermined compression format, and the result is stored in the external memory 7 (normal flash memory). Use a non-volatile memory such as a memory).

  When the photographer displays the photographed image data by operating the camera operation switch 11, the data compressed and stored in the external memory 7 is expanded to normal data for each photographing pixel through the memory control unit 5.
