Patent ID: 8269865

Claim:
A signal processing apparatus that performs predetermined signal processing on an image signal output from an image sensor having a pixel array in which a plurality of pixels are arrayed in a direction along a row and a direction along a column, the signal processing apparatus comprising: a storage unit that stores characteristic information indicating characteristics of signal component mix in each pixel from adjacent pixels according to the pixel position in the pixel array of the image sensor; and a correction unit that calculates a correction coefficient according to the position of a pixel for correction in the pixel array from the characteristic information, and corrects an output image signal of the pixel for correction based on an output image signal of adjacent pixels of the pixel for correction and the calculated correction coefficient, wherein the characteristic information includes a coefficient table in which, for each pixel, a pixel position in the pixel array is associated with a correction coefficient that has been determined in advance so as to correct a signal component that mixes in each pixel from adjacent pixels, and the correction unit calculates the correction coefficient according to the position of the pixel for correction in the pixel array and the coefficient table.
