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 a non-high dynamic range (HDR) mode: capturing first video data of a scene with the image sensor; determining whether a minimum number of pixels of the first video data meets one or more first color intensity criteria; and in accordance with the determination that the minimum number of pixels of the first video data meets the one or more first color intensity criteria, switching operation from the non-HDR mode to an HDR mode.
