Patent ID: 6914628

Claim:
An image processing apparatus performing image processing on image data consisting of dot-matrixed pixels, each of the dot-matrixed pixels having color element data from all element colors, the dot-matrixed pixels being output from an input device which generates the image data by obtaining image data by a single-plate solid image pickup device where a plurality of color filters of element color components are arranged in mosaic, said apparatus comprising: a color-blur pixel detection unit detecting a color blur pixel in said image data; and an image processing unit performing image processing on pixels, each of the pixels having data from all the element colors, the pixels being within a predetermined range having said detected color blur pixel as a reference pixel, so as to reduce a color blur; wherein said color-blur pixel detection unit detects said color blur pixel based on change rate of element color intensity for a low-density color filter, between closely adjacent pixels.
