Automatic exposure metering for regions of interest that tracks moving subjects using artificial intelligence

Abstract

An apparatus comprising an interface and a processor. The interface may be configured to receive pixel data. The processor may be configured to process the pixel data arranged as video frames, generate statistics and a timestamp for the video frames, perform computer vision operations on the video frames to determine one or more regions of interest within the video frames at the timestamp, track a movement of the regions of interest over a sequence of the video frames, evaluate a current luma value of the regions of interest, calculate auto-exposure parameters in response to the current luma value and a target luma value and generate an output signal comprising the auto-exposure parameters. The auto-exposure parameters may be calculated to prioritize an exposure of the regions of interest in the video frames and dynamically change the auto-exposure parameters based on the movement of the regions of interest.
