Abstract:
1. An image processing device that corrects a pixel value in image data, comprising: an input unit that inputs image data having a plurality of color components and including a plurality of pixels each holding one color component among the plurality of color components; a calculation unit that calculates a maximum value among pixel values of a plurality of same-color neighboring pixels and pixel values of a plurality of different-color neighboring pixels, each of the plurality of same-color neighboring pixels holding a color component identical to a color component held in a processing target pixel selected from the pixels included in the image data, each of the plurality of different-color neighboring pixels holding a color component different from the color component held in the processing target pixel, the plurality of different-color neighboring pixels being located closer to the processing target pixel than the plurality of same-color neighboring pixels; and a correction unit that compares a pixel value of the processing target pixel with the maximum value and replaces the pixel value of the processing target pixel with the maximum value if the pixel value of the processing target pixel is greater than the maximum value.
