ABSTRACT:
An image processing system and method capable of reducing hardware scale to improve processing speed. The G conversion section includes a third product producer for producing a third product from a first intermediate product corresponding to a first common partial bit string of multipliers of a color difference Cr for R and G conversions, and a fourth product producer for producing a fourth product from a second intermediate product corresponding to a second common partial bit string of multipliers of a color difference Cb for B and G conversions, and intermediate calculation data of a fixed factor multiplication of the color difference Cr for the R data conversion and intermediate calculation data of a fixed factor multiplication of the color difference Cb for the B data conversion are utilized for the conversion calculation of the data G.
