PIXEL SIGNAL PROCESSING APPARATUS AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pixel signal processing apparatus capable of suppressing the generation of a false color in the result of interpolation even in a region wherein no similarity relation exists in behaviors of changes in color components, and carrying out the interpolation at all times by using an optimum interpolation method independently of ways of changes in color component values of pixels around a target pixel.

SOLUTION: The pixel signal processing apparatus is provided with two interpolation means (31, 12) for interpolating deficient color component values by adopting methods different from each other and interpolates the deficient color component value by combining (13) the deficient color component values calculated by the two interpolation means. One of the interpolation means (31) may perform the interpolation by a regression analysis or linear interpolation. The other interpolation means (12) may perform the interpolation utilizing the similarity of a change between different colors.
