Patent ID: 8542299

Claim:
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 an image sensor with a matrix of units, a unit comprising one or more R (red), one or more G (green) and one or more B (blue) pixels, and wherein, at the pixel position in the above mentioned-color image corresponding to an above mentioned unit, a 1 st color difference is generated by subtracting the sum of respective-R pixel signals for said R pixels in said unit and of respective B pixel signals for said one or more B pixels in said unit from the sum of respective G pixel signals for said one or more G pixels in said unit, the image processing device comprising a synchronization facility for generating a 2 nd color difference by calculating the difference between the sum of the above mentioned respective R pixel signals and the sum of the above mentioned respective B pixel signals, and the image processing device comprising a pseudo-color suppression facility for suppressing pseudo-color in at least one of the above mentioned 1 st color difference and 2 nd color difference, a color space conversion facility for converting the pseudo-color suppressed 1 st color difference and 2 nd color difference obtained from the pseudo-color suppression facility using said luminance into a determined color space and for generating the above mentioned color information.
