Abstract
In a scene-by-scene color corrector, automatic color correction circuitry produces color correction signals which are stored and utilized in preparing color-corrected video tape. Preferably, the automatic correction circuit tests only a pre-selected portion of the video picture displayed on a monitor. This portion or 'window' is visible on the monitor screen, and its position and size can be changed as desired. The use of the 'window' permits the exclusion of portions of the picture on which the automatic circuitry is less than fully effective, or which do not have components desirable for use in automatic color correction. If a separately variable luminance signal is produced, the automatic color correction circuitry preferably uses the luminance signal as a reference, thus allowing one to maintain color balance despite changes in the luminance signal.
