Area isolation apparatus for video signal control system |
摘要 |
A video parameter control system operative for selecting a spatial region in a video image for correction, particularly useful for a scene by scene color corrector. A track ball allows selection of a spatial region by drawing a "window" with a cursor around an object of interest in the picture. The operator then adjusts controls for the selected region or window. A first set of correction signals will be stored for the selected region; a separate second set of correction signals is stored for areas of the picture outside the selected regions, thereby allowing multiple sets of corrections for a given frame. A plurality of windows can be selected for each video frame. If an object within the window translates across the screen over a plurality of frames, or is dissolved, zoomed, or warped, the window tracks the movement of the object.
