Abstract
Disclosed systems and methods for off-axis color correction in dynamic image capture of video wall displays involve measuring color performance of specific LED tiles or video walls and providing a database to store the characteristics of these off-axis measurements for use in color correction. The database is accessible by a color correction engine associated directly or indirectly with the video rendering engine so that when combined with real-time information on camera view angle and field of view relative to the display, a color correction function can be incorporated into the rendering of the display portion within the field of view of the camera so as to reduce or eliminate off-axis color variations/distortions in the captured image.
