Abstract
PURPOSE:To eliminate a color shift and ghost by encoding pieces of color-separated picture information into binary signals and by determined color information via shift resistors, on the basis of the outputs, by using the relative information distribution of time domain of color signals. CONSTITUTION:For example, picture signals read via both filters 2R and 2C for red and cyan are compared with reference voltages VrR and VrC by using binary- coding circuits 8R and 8C and they are used as threshold levels to generate binary- coded signals Rin and Cin, then these are applied to discriminating circuit 9. The both are applied to shift registers SHR and SHC in series and, on the basis of their parallel outputs, the readout address of color data memory 9RB stored with data previously is determined to relative information distribution of time series of picture signals Rin and Cin, thereby determining two pieces of color picture information Rout and Bout. Thus, a color shift and ghost are reduced.
