An image processing apparatus includes an image-frame reading section that reads one or more image frames from a moving image, a region-boundary-line-information receiving section that receives information concerning a region boundary line in the read image frames, a region dividing section that expands a division region starting from a point on the region boundary line and divides the inside and outside of the region boundary line with division lines, which connect points of brightness, an opening processing section that leaves a first division line between a pair of the region boundary lines and opens a second division line, a separating section that separates regions in the image frames in units of a region surrounded by the first division line, and a first depth-value giving section that gives, to the region surrounded by the first division line, a depth value representing a distance degree of the region.
