Apparatus for adjusting hue, chrominance, and luminance of a video signal using matrix circuits

摘要

Disclosed herein is an apparatus for carrying out color correction on a video signal. The apparatus basically comprises a Y/C separating circuit for separating the video signal into a luminance signal and a color signal, a decoder for decomposing these signals into color separation signals, three three-row/three-column type color- correcting matrix circuits for electrically processing the color separation signals for color correction, an A/D converter circuit for converting the so- processed signals into digital signals, a frame memory for storing the digital signals therein as data, a correction circuit and a printer head. By using the apparatus referred to above, a user can emphatically perform correction on the hue, chroma and luminance of each of specific colors. Thus, the user can adjust the quality of an image with extreme ease.
