US Patent 10397469 Dynamic image-based adjustment of image capture parameters

A portable electronic device with image capturing capabilities automatically or semi-automatically adjusts one or more image capturing parameters based on an image metric calculated from image data captured by the device. The device can be configured for processing image data captured by an on-board camera to determine the image metric, and to perform an automated adjustment action based on the determined value of the image metric. In some embodiments, the image metric is an image brightness metric upon which automated adjustment of a camera sensitivity parameter is based.
