Abstract: An illustrative apparatus may identify, within an image frame captured by an image capture system, a signal region that includes pixels having auto-exposure values exceeding an auto-exposure value threshold. The apparatus may adjust, based on the auto-exposure values of the pixels included within the signal region, one or more auto-exposure parameters used by the image capture system to capture an additional image frame. Additionally, the apparatus may determine, based on a size of the signal region within the image frame, whether to change the auto-exposure value threshold. Corresponding apparatuses, systems, and methods for managing auto-exposure of image frames are also disclosed.
