PURPOSE:To improve the picture quality and to change color tone or the like by applying electric processing to a color contrast signal and utilizing a color output means to attain color copying and display. CONSTITUTION:An original 1 is separated into three colors Y, M, C, they are converted into electric signals by CCD solid-state image pickup elements 4-1-4-3 and the signals are applied with a unique digital processing at a signal processing circuit 7 on the way. Further, the signals are converted into Y', M' and C' signals, ink nozzles of three Y, M, C colors are driven so as to obtain a color copy by subtractive color mixture again on paper on a paper drum 9. |
