Abstract
Methods, apparatuses, computer-readable medium, and systems are disclosed for performing automatic exposure control (AEC). In one embodiment, a first digital image is captured while applying a first set of values to one or more exposure control parameters. At least one computer vision (CV) operation is performed using image data from the first digital image, thereby generating a first set of CV features from a set of possible CV features. A mask is obtained comprising a value for each feature of the set of possible CV features. Using the mask, a first measure of abundance is obtained of relevant CV features among the first set of CV features extracted from the first digital image. Based on the first measure of abundance of relevant CV features, an updated set of values is generated for applying to the one or more exposure control parameters for capturing a subsequent digital image of the scene.
