PURPOSE:To store a video signal into a memory and to adjust the hue and saturation or the like of a picture by varying a conversion coefficient by means of a variable resistor when a luminance signal and a color difference signal stored in the memory are converted into R,G,B primary color signals by an RGB decoder. CONSTITUTION:An inputted video signal is stored in memories 50-52 as a luminance signal and a color difference signal and the luminance signal and the color difference signal are converted into R,G,B primary color signals by an RGB decoder 63, then the conversion coefficient is varied by variable resistors 60-62. That is, the adjustment position of the variable resistors 60-62 for saturation and hue is inputted as a data to a microcomputer 66 and the microcomputer 66 varies the coefficient for calculation accordingly. Then a selector 64 selects R,G,B signals outputted from the RGB decoder 63 for every print of one color and the result is fed to a print engine 65. Thus, the hue and the saturation or the like are adjusted in the component signal memory system. |
