SOLUTION: To which of the closest view 64, a close view 62, focus depth 60, a distant view 58 or the most distant view 56 each pixel belongs is decided based on Z value held in a Z buffer. Alpha values (depth range information) corresponding to depth ranges are set in respective pixels. Translucent composition of color information of each pixel is performed with color information of other pixels in forms corresponding to the alpha values. For example, the translucent composition is performed for an original image by shifting prescribed pixels to the left and right for the pixels belonging to the distant view 58 and the most distant view 56. In addition, the translucent composition is further performed to the original image by shifting up and down by prescribed pixels for the pixels belonging to the closet view 56.
