ABSTRACT:
An apparatus and method for generating an image by 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. The method includes detecting a correlation value indicative of a degree of correlation in each of the at least two directions of the interpolated pixel data, and normalizing the correlation value of each of the at least two directions. A predetermined correction value is added to the normalized value, and the interpolated pixel data is weighted 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.
