Abstract The method and device of the present invention can detect and regulate timely the color of different points in a TV image, for example, it can makes tree and grass exhibit light green color. For each color, one color coordinate detecting circuit and one color coordinate shifting control circuit are designed and set between the TV signal output and the video driving amplifier, the former detects the points to be color shifted and the latter changes the bias current or bias voltage output to the video driving amplifier of color TV, so that the three-color electronic gun connected to the amplifier produces color shift in some point of display screen.
