Abstract:
1. An image processing device for generating a color image, having a plurality of color information for each pixel, from a color mosaic image obtained from a Bayer pixel array filter equipped CCD with red (R), green next to the R in one direction of the pixel array (Gr), blue (B), and green next to the B in the one direction (Gb) pixels, wherein, at a pixel position in the color mosaic image with the R, Gr, Gb and B pixels as a single unified unit, a luminance (Y) is generated from a sum of R, Gr, Gb and B pixel signals and a first color difference is generated by subtracting the R pixel signal and the B pixel signal from a sum of the Gr pixel signal and the Gb pixel signal, the image processing device furthermore comprising: a synchronization facility for generating a second color difference by calculating a difference between the R pixel signal and B pixel signal; a pseudo-color suppression facility for suppressing pseudo-color in at least one of the first color difference and the second color difference; and a color space conversion facility for converting the pseudo-color suppressed first color difference and/or second color difference, obtained from the pseudo-color suppression facility, using said luminance, into a determined color space for generating the color information.
