Abstract
An aspect ratio converter converts a still image signal having an aspect ratio of 4:3 to a still image signal having a predetermined wide aspect ratio. A both-end pixel extractor extracts predetermined amounts of both left and right end images of a horizontal scanning period of the still image signal having an aspect ratio of 4:3. A both-wing image data preparing unit and a both-wing extrapolator use the extracted images to extrapolate a region of from both left and right ends of the horizontal scanning period of the still image signal having an aspect ratio of 4:3 to both left and right ends of the horizontal scanning period of the still image signal having the wide aspect ratio.
