  • Color and brightness calibration for video stitching
    Patent number: 10666919
    Abstract: An apparatus includes a plurality of cameras and a circuit. The cameras may be mounted on a vehicle and configured to generate a plurality of initial video signals of a scene outside of the vehicle. A plurality of fields of view of adjoining ones of the cameras may spatially overlap each other. The circuit may be configured to (i) store calibration values of the cameras generated during a calibration process, (ii) modify at least one of the initial video signals by applying the calibration values and (iii) generate a final video signal suitable to display to a user of the vehicle by stitching together the initial video signals. The calibration values may be used by the circuit to generate approximately continuous brightness within the scene in the final video signal.
