Camera movement control for reduced power consumption

Abstract:

Various embodiments include camera movement control for reduced power consumption. Some embodiments, for example, may include operating a camera module in a power saving mode, in which focus movement control may be synchronized with frame capture. According to some examples, such synchronization may include holding a position (e.g., a focus position) of a lens group and/or an image sensor of the camera module during some integration time periods. Furthermore, such synchronization may include enabling power saving movement (e.g., between a focus position and a neutral position) of the lens group and/or the image sensor during some other time periods, such as during intervals (e.g., blanking intervals) between integration time periods, and/or during integration time periods for image frames that are expendable.
