PURPOSE: An image quality compensation and control device is provided to control the size of a combined video signal output from a buffer to apply it to a differentiators, thereby displaying a natural and clear image without noise. CONSTITUTION: An image quality compensation and control device comprises a micom(1A), a color treatment unit(5A) and a video signal size controller(12). The micom(1A) receives and checks AGC(automatic gain control) voltage changed in order to the signal input to a tuner(2) to control a system. The color treatment unit(5A) controls sharpness in order to display optimum image by the micom(1A). The controller(12) controls the size of a combined video signal output from a buffer(9) to apply it to a differentiators(10). |
