<P>PROBLEM TO BE SOLVED: To appropriately remove background, to maintain hue even if background is not removed, and further, to perform image processing with high resolution. <P>SOLUTION: R, G and B signals read by a 4-line color CCD sensor are converted into C, M and Y color signals. A black/white signal is generated from a luminance signal read by the 4-line color CCD sensor. Densities of the C, M and Y color signals are converted on the basis of the black/white signal. <P>COPYRIGHT: (C)2009,JPO&INPIT |
