IMAGE SIGNAL CORRECTING DEVICE, IMAGING DEVICE, IMAGE SIGNAL CORRECTING METHOD, AND PROGRAM

摘要

An image signal correcting device (15) has at least a color mixing corrector (151) that receives an image signal arising from photoelectric conversion by a color imaging element (12), and corrects a color mixing component included in this image signal, and a storage unit (153) that stores a color mixing correction coefficient set in advance for each of a plurality of areas segmented in matching with the imaging plane of the imaging element (12). The color mixing corrector (151) approximates the color mixing correction coefficient read out from the storage unit (153) by interpolation to acquire a color mixing rate at the necessary pixel position in color mixing correction, and corrects the color mixing component by using the acquired color mixing rate.

1. An image signal correcting device comprising:
at least a color mixing corrector configured to receive an image signal arising from photoelectric conversion of a color imaging element, and correct a color mixing component included in the image signal; a shading corrector configured to receive the image signal corrected by the color mixing corrector, and carry out pixel shading correction for the corrected image signal; and wherein the color mixing corrector configured to divide the image signal into a plurality of image groups, respectively decide a color mixing rate of each of the image groups by interpolation processing, and correct the color mixing component by the acquired color mixing rate.
