ABSTRACT:
Camera signal processing for interpolating, at least on two directions, pixel data based on an imaging signal from a solid-state image sensor in which an imaging light enters through a color filter having a different spectral characteristic for each pixel separately generating interpolated pixel data in the directions, detecting a correlation value indicative of a degree of correlation in each of the directions of the interpolated pixel data, normalizing the correlation value of each of the directions to generate a normalized value indicative of a relative value of the correlation value of each of the directions, adding a predetermined correction value to the normalized value, weighting the interpolated pixel data by the normalized value and adding together the weighted interpolated pixel data, and generating an image based on the interpolated pixel data weighted by the weighting means.
