Abstract:
1. An image processing device, comprising: a pixel signal extraction portion that extracts from image data a pixel signal array formed of pixel signals of a plurality of pixels located in an image height direction, separately for each color component; a filter processing portion that applies a filter having a plurality of tap coefficients corresponding to the number of pixels in the pixel signal array to the extracted pixel signal array, and generates a correction signal array; and a signal array addition portion that adds the generated correction signal array to the pixel signal array, and generates a processed signal array, wherein the plurality of tap coefficients include one reference tap coefficient having a maximum value that is applied to a pixel of interest in the pixel signal array, and negative tap coefficients having negative values that are applied to surrounding pixels around the pixel of interest located in the image height direction, in a tap coefficient array in which the tap coefficients to be applied to the pixel signals located sequentially in the image height direction are sequentially arranged so as to correspond to the pixel signals, the reference tap coefficient is positioned off center at a position other than the center of the plurality of tap coefficients, and, among the negative tap coefficients located on both sides of the reference tap coefficient in the tap coefficient array, the number of the negative tap coefficient on a first side is one, and the number of the negative tap coefficients on a second side is two or more.
