PROBLEM TO BE SOLVED: To improve interpolation processing and to enhance color reproductivity in a single plate electronic camera using a color mosaic filter. SOLUTION: Average values R', G' and B' of each signal R, G and B are calculated within 5×5 pixel area with a remarked pixel as a center in an electronic camera using an RGB mosaic filter (S3). For instance, in a remarked pixel where a B filter is laminated, when a signal value in the remarked pixel is B, the interpolation value g of G is calculated as g=G'+B-B', and the interpolation value r of R is calculated as r=R'+B-B' (S4).
