Abstract
Apparatus that is self-contained with video equipment, such as a video camera or video record/playback device, and which generates video signal adjustment data for use by video signal processing circuits that are included in such video equipment. An input video signal is coupled to luminance and/or chroma digital signal processing circuits which are supplied with luminance or chroma adjustment control data, respectively, for subjecting the input video signal to predetermined luminance or chroma adjustment operations, thereby producing adjusted digital luminance and chroma signals, respectively. At least one of the adjusted digital luminance and chroma signals is sampled at preselected times; and the sampled digital signals are used by an adjustment control data generator for generating the luminance and/or chroma adjustment control data that are supplied to the luminance and/or chroma digital signal processing circuits.
