Image processing device, correction information generation method, and image-capturing device
Abstract:
An image processing device that corrects and interpolates pixel values of defective pixels present upon an image sensor, includes: a position information storage memory that stores a position of a defective pixel of a first type whose pixel value can be utilized after correction, and a position of a defective pixel of a second type whose pixel value is to be interpolated using pixel values of other pixels, distinguished from one another; a correction amount storage memory that stores a correction amount for the defective pixel of the first type; a correction unit that corrects the pixel value of the defective pixel of the first type according to the correction amount; and an interpolation unit that interpolates the pixel value of the defective pixel of the second type, using the pixel values of pixels including the defective pixel of the first type whose pixel value has been corrected by the correction unit.
