Abstract
PURPOSE:To suppress color mixing and to code in a short time by discriminating that original picture image data fetched by a TV camera and digitized is a natural picture or a picture such as a graphic and an animation by an operation means, and executing a color compression based on this. CONSTITUTION:An original picture fetched by a TV camera 10 is converted into analog signals R, G and B, they are inputted in parallel to an AD converter 20 constituted of three for the R, for the G and for the B and converted into one screen at every one frame period. Next, R, G and B digital data are stored into a frame memory 30 constituted of the three semiconductor memories having the number of addresses larger than the number of picture elements for one frame, these are read out by a computer 40 based on a command from a graphic terminal 50 and the distribution curve of respective components are obtained. Thereafter, it is judged that it is the natural picture or an animation picture or a graphics picture from this curve, after that, compression is executed, a central value is set, it is coded, formatted, sent to a recording device 60 and recorded onto an optical disc.
