Plate making system for video picture

Abstract

Abstract PURPOSE:To perform easily and securely plate making of high quality by reproducing a desired picture signal from a master tape on the bais of a time code and correcting it, and then converting it into an R, G, and B signal and storing them for the plate making. CONSTITUTION:Time codes from a time code memory 37, an external memory 38, etc., are specified selectively through a console panel 50 and a desired picture signal recorded on the one-inch tape of a VTR32 together with a time code is reproduced. This reproduction output is corrected at the picture quality improving part 60 consisting of a time base corrector 61, noise reducer 62, detail corrector 63, etc., to obtain a high-quality picture signal, which is converted by an RGB decoder 52 into an R, G, and B color signal. Then, those color signals are corrected by a gradation correcting part 72 independently of one another and stored on a floppy disk 81, etc., and those storage contents are used to perform easily and securely the high-quality plate making on the basis of the color signals of high quality with excellent resolution without an image picking up a CRT video image by a TV camera.
