Abstract:
An image processing apparatus includes: an acquisition unit configured to obtain image data generated by an image sensor forming an array pattern using color filters having mutually different spectral transmittances and to obtain a correction coefficient for correcting a difference between pixel values corresponding to a difference between a spectral sensitivity and a preset reference spectral sensitivity in a wavelength range in a pixel-of-interest; a correction amount calculation unit configured to calculate an estimation value of a color component in the pixel-of-interest using a pixel value of each of pixels in surrounding pixels of a same color and the correction coefficient and configured to calculate a correction amount of the pixel value of the pixel-of-interest based on the estimation value and the correction coefficient of the pixel-of-interest; and a pixel value correction unit configured to correct the pixel value of the pixel-of-interest based on the calculated correction amount.

Claim (Index 12):
An image processing method comprising:\n obtaining image data generated by an image sensor that forms a predetermined array pattern using color filters of a plurality of colors having mutually different spectral transmittances and in which each of the color filters is arranged at a position corresponding to any of a plurality of pixels and obtaining a correction coefficient from a recording unit configured to record, for each of the pixels, the correction coefficient for correcting a difference between pixel values corresponding to a difference between a spectral sensitivity and a preset reference spectral sensitivity in a predetermined wavelength range in a pixel-of-interest; calculating an estimation value of a color component as a correction target in the pixel-of-interest using a pixel value of each of pixels in a surrounding pixel of a same color and the correction coefficient, the surrounding pixel of a same color being a pixel surrounding the pixel-of-interest and being a pixel including a color filter having a same color as a color filter arranged on the pixel-of-interest; calculating a correction amount of the pixel value of the pixel-of-interest based on the estimation value and the correction coefficient of the calculated pixel-of-interest; and correcting the pixel value of the pixel-of-interest based on the calculated correction amount.
