Abstract:
1. An image processing apparatus for producing a restoration image wherein each pixel has all of a plurality of color components using a color and sensitivity mosaic image wherein each pixel has a sensitivity and one of the plurality of color components and a color mosaic image wherein each pixel has one of the plurality of color components, the image processing apparatus comprising: a sensitivity uniformization unit for uniformizing the sensitivities of the pixels of the color and sensitivity mosaic image; a first color difference image production unit for producing a first color difference image corresponding to the color mosaic image based on color mosaic pattern information which indicates an arrangement of the color components of the color mosaic image, wherein said first color difference image production unit includes: a second color difference image production unit for producing a second color difference image corresponding to the color mosaic image based on the color mosaic pattern information, wherein the second color difference image production unit includes: a luminance image production unit for producing a luminance image using: (i) the first color difference image; (ii) the second color difference image; and (iii) the color mosaic image; and a restoration unit for restoring all of the color components corresponding to each pixel using: (i) the first color difference image; (ii) the second color difference image; and (iii) the luminance image.
