Abstract:
1. A motion estimation system, comprising: a predetermined number of separate storage units for an integer pixel search that receive luminance data of integer-pixel of integer-pixel accuracy in a prescribed image area, divide the luminance data of integer-pixel accuracy in the prescribed image area, and store said luminance data by a prescribed unit as stored luminance data; and an integer pixel motion estimation section that extracts a prescribed reference extracted area based on a combination of said stored luminance data read from said predetermined number of separate storage units for the integer pixel search and performs motion estimation with integer-pixel accuracy, wherein in said predetermined number of separate storage units for the integer pixel search, said stored luminance data corresponding to pixels adjacent in a horizontal direction and a vertical direction and four consecutive said stored luminance data corresponding to pixels adjacent in said horizontal direction are distributed among said predetermined number of separate storage units for the integer pixel search to be able to be simultaneously extracted from said predetermined number of separate storage units for the integer pixel search by one reading operation.
