1. A method comprising:
receiving a first image from an image sensor, the first image captured with a first field of view (FOV) and comprising a first plurality of pixels;
applying first weights to the first plurality of pixels;
receiving a second image from the image sensor, the second image captured with a second FOV and comprising a second plurality of pixels;
determining a region of interest (ROI) in the second image, the ROI in the second image comprising a subset of the second plurality of pixels in the second image;
determining an ROI weight for the ROI in the second image, wherein the ROI weight for the ROI in the second image comprises a combination of the first weights applied to the first plurality of pixels and an ROI value;
determining statistics based on the first plurality of pixels in the first image, the subset of the second plurality of pixels in the second image, and the ROI weight for the ROI in the second image; and
adjusting a gain or exposure setting for the image sensor based on the statistics.
