Abstract
A digital still camera includes a shutter release button. A first gamma correction circuit, when a shutter release button is depressed, references a first gamma table to correct a camera signal by a gamma characteristic of a raster scan display, creating a first image signal. The first image signal is subjected to interpolation/thinning-out and image processing by a first signal processing circuit. A thinned-out image signal is corrected in a second gamma correction circuit by a gamma characteristic for converting a raster-scan display gamma characteristic into a dot-matrix display gamma characteristic, thereby creating a second image signal. The second image signal is displayed on an LCD (Liquid Crystal Display). The first image signal is also subjected by a second signal processing circuit to interpolation, YUV conversion and JPEC compression so that a compressed image signal is stored in a memory flash. The compressed image signal is read out of the flash memory as required, to be outputted to a CRT.
