Abstract:
A technique for applying black level compensation to image data is provided. In one embodiment, an image processing system includes a first image processing pipeline configured to receive frames of image data generated by an image sensor and to alter the frames of image data to compensate for black level shift. The image processing system may also include a feed-forward loop having a second image processing pipeline configured to receive at least one of the frames of image data, to process the at least one frame, and to adjust a black level compensation parameter of the first image processing pipeline. Additional methods, systems, and devices relating to black level compensation are also disclosed.
