A color imaging device uses a color imaging element in which an RGB filter corresponding to each RGB color is positioned periodically, and having a color filter arrangement containing a section where the G filter, which contributes the most for acquisition of a luminance signal, is positioned so as have two or more thereof in each of the horizontal, vertical, and diagonal (NE, NW) directions (four directions). Also, on the basis of the pixel values of the adjacent G pixels in each direction, which of the four directions is the luminance correlation direction is determined by a minimum pixel interval. When calculating the pixel value for another color at the pixel location of the pixel to be subjected to simultaneous processing that was extracted from a mosaic image, the value of the pixel of the other color is accurately estimated by making the determination, and using the pixel value of the pixel of the other color present in the determined correlation direction. |
