Patent ID: 8767103

Claim:
An image processing apparatus for receiving a light signal and generating image data based on the light signal for each pixel, the light signal being acquired by each pixel by inputting to a predetermined color filter through a lens and including one of plural different spectrum component, the apparatus comprising: contrast component operating means for operating a contrast component of the image data based on a first pixel value corresponding to the light signal on a predetermined pixel and a second pixel value resulting from interpolation processing performed using a pixel value of a pixel adjacent to the predetermined pixel; wherein the contrast component operating means obtains the contrast component of the image data based on operational processing by using, between the first pixel value and the second pixel value, a pixel value corresponding to a first spectral component having a widest frequency bandwidth among the plural different spectral components, a pixel value corresponding to a second spectral component corresponding to a predetermined frequency band close to a frequency that causes no chromatic aberration of the lens, or a third pixel value corresponding to a third spectral component expressed in terms of a linear sum of a value resulting from multiplying the first spectral component by a first weighting factor and a value resulting from multiplying the second spectral component by a second weighting factor.
