Abstract
The various implementations described herein include methods, devices, and systems for implementing high dynamic range and automatic exposure functions in a video system. In one aspect, a method is performed at a video camera device and includes, while operating in an HDR mode: (1) capturing video data of a scene, including: (a) capturing a first subset of the video data with a first exposure time; and (b) capturing a second subset of the video data with a second exposure time, lower than the first exposure time; (2) determining whether the first subset of the video data meets first criteria; (3) determining whether the second subset of the video data meets second criteria; (4) in accordance with a determination that the first subset meets the first criteria or a determination that the second subset meets the second criteria, switching operation from the HDR mode to a non-HDR mode.
