Abstract

An illustrative apparatus may determine a color-skew metric for an image frame captured by an image capture system. The color-skew metric may be indicative of an extent to which the image frame skews to a particular color. Based on the color-skew metric and an adaptive target control function, the apparatus may determine a frame auto-exposure target. Based on the frame auto-exposure target, the apparatus may update one or more auto-exposure parameters for use by the image capture system to capture an additional image frame. Corresponding apparatuses, systems, and methods for managing auto-exposure of image frames are also disclosed.
