Picture processor

Abstract

Abstract PURPOSE:To surely eliminate a color ghost with a simplified constitution, by performing a picture processing after color ghost correction is applied on picture information after color separation. CONSTITUTION:Optical images separated by a color separation optical system (not shown in figure), after being photoelectric-converted by every picture element at CCDs 1 and 2, are converted to normalized digital data at following A/D converters 41 and 42. A luminance signal data (VR+Vc) corresponding to an input address is outputted from a (VR+Vc) memory, and a color difference signal data Vc/(VR+Vc) corresponding to the input address is outputted from a Vc/(VR+Vc) memory. And these data are inputted commonly to color separation memories 62-64 as addresses. From a black memory 62, a red memory 63, and a cyan memory 64, picture data corresponding to the input addresses are outputted, and are inputted to a color ghost elimination circuit 100. And after color ghost elimination is performed on them, density information, and color codes corresponding to the bit of density information, are outputted.
