Apparatus for processing a video signal to generate video signal adjustment data that is self-contained with the video equipment

Apparatus for generating video signal adjustment data for use by video signal processing circuits of the type that are included in video equipment, said apparatus being self-contained with video equipment and comprising:

• input means for providing an input video signal to be processed by said video signal processing circuits;
• luminance digital signal processing means supplied with luminance adjustment control data for subjecting said input video signal to predetermined luminance adjustment operations to produce adjusted digital luminance signals;
• chroma digital signal processing means supplied with chroma adjustment control data for subjecting said input video signal to predetermined chroma adjustment operations to produce adjusted digital chroma signals;
• sampling means for selectively sampling at least one of the adjusted digital luminance and chroma signals at preselected times;
• and
• adjustment control data generating means coupled to said sampling means and responsive to the sampled digital signals for generating at least one of said luminance and chroma adjustment control data and for supplying said at least one of said luminance and chroma adjustment control data to at least one of said luminance and chroma digital signal processing means to subject said input video signal to luminance and chroma adjustment operations, respectively.
