Abstract:
When determining that a pixel of a future frame, which is included in a search range, includes a pixel on an outside of an effective image area, and determining that pixels inside an effective image area of a past frame are present at positions point-symmetric to pixels inside the search range and on an outside of the effective image area about a pixel of interest, a pixel selector selects pixels in an effective image area of a past frame, the pixels being located at the point-symmetric positions. The pixel selector calculates difference values between the pixel of interest and the selected pixels inside the effective image area of the past frame.
