Abstract

A signal processor of an electronic still camera stores image data, obtained during photographing, into a buffer memory. A gain adjusting circuit performs multiplication on the stored image data with the exposure amount changed by 0.5 EV at a time. Next, a usage-specific processor processes the image data in one of two ways to change the gradation, contour, and so on, of the image data so that the image data may be output appropriately to a CRT or a printer.
