Abstract
This apparatus obtains a mapped position (xo, yo) of (xi, yi), acquires (xi', yi′) by performing inverse mapping for each reference position being based on (xo, yo), obtains (xi″, yi″) by performing inverse mapping for integer parts xoc and yoc of xo and yo respectively, and performs interpolation using fraction parts of x- and y-coordinates of a position, of (xi″, yi″) and (xi′, yi′), whose integer parts of the x- and y-coordinates respectively coincide with xi and yi, and peripheral pixel values of (xi, yi).
