Abstract
Systems and methods for adjusting color and brightness in multi-camera systems are disclosed. The system uses four cameras, having overlapping fields of view, mounted on the four sides of a vehicle. Color errors are determined for areas where the images from the rear and side cameras' fields of view overlap. Color gain factors are determined and applied for each of the side cameras (using the rear camera as 'master') to match the colors of the video outputs from the side cameras and the rear camera. The gains for the front view camera are then adjusted using gain factors based on the matched video outputs from the side view cameras using the side cameras as the 'master' to the front camera “slave.” In this way, the rear camera indirectly acts as the master for the front camera and all cameras are ultimately color-matched to the rear camera.
