Method and apparatus for multiple zone statistics collection for digital image/video capture systems

摘要

A system includes a block module, a zone module, a statistics module, and a control module. The block module is configured to associate pixel values generated by pixel sensors of an image sensor with M regions. The zone module is configured to define N zones in the M regions. Each of the N zones includes an adjustable number of the M regions. N and M are integers greater than one and N is less than or equal to M. The statistics module is configured to gather statistics corresponding to the N zones. The control module is configured to adjust pixel values generated by the pixel sensors based on the statistics.
