ABSTRACT:
Provide an electronic still camera using a color filter array (CFA) and a single CCD making it possible to simultaneously execute the processing for color signal interpolation and the processing for resizing. In the electronic still camera according to the present invention, an R signal, a G signal, and a B signal are output from each pixel of an image sensor12having a CFA. A processor16simultaneously executes processing for interpolation and processing for resizing by computing (R, G, B) values at a given pixel position according to the color signals. Low frequency components Rlow, Glow, Blowof the color signal at the given pixel position are computed from signals from adjoining pixels, and the high frequency component Shighis computed from a brightness value Y. The image data interpolated and changed to a desired size is stored in a memory18, or is output via an interface I/F20to an external device such as a computer or a printer.
