Abstract
A camera signal process and apparatus 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 at least two directions, detecting a correlation value indicative of a degree of correlation in each of the at least two directions of the interpolated pixel data, normalizing the correlation value of each of the at least two directions to generate a normalized value indicative of a relative value of the correlation value of each of the at least two directions, adding a predetermined correction value to the normalized value, weighting the interpolated pixel data in each of the at least two directions by the normalized value and adding together the weighted interpolated pixel data in all of the at least two directions, and generating an image based on the interpolated pixel data.
