Abstract
Tap coefficients of a filter include one reference tap coefficient having a maximum value that is applied to a pixel of interest in a pixel signal array, and negative tap coefficients having negative values that are applied to surrounding pixels around the pixel of interest located in an image height direction. In a tap coefficient array in which the tap coefficients to be applied to pixel signals located sequentially in the image height direction are sequentially arranged, the reference tap coefficient is positioned off center at a position other than the center of the tap coefficients. Among the negative tap coefficients located on both sides of the reference tap coefficient in the tap coefficient array, the number of the negative tap coefficient on a first side is one, and the number of the negative tap coefficients on a second side is two or more.
