Abstract
An electronic still camera includes a plurality of image pickup elements having color filters of a plurality of colors; a color separation unit for separating outputs from the image pickup elements into each color signal; an interpolation unit for receiving an output from the color separation unit and interpolating missing part of each color image data; an orthogonal transformation unit for dividing respective color image data interpolated by the interpolation unit into a plurality of blocks and performing orthogonal transformation, a coding unit for coding an output from the orthogonal transformation unit; and a storage unit for storing an output from the coding unit.
