Abstract: Various implementations disclosed herein improve the appearance of captured video by accounting for motion-induced blur, noise, lighting, and/or other factors related to the appearance of video captured by rotating or otherwise moving wearable electronic device. Some implementations reduce or eliminate camera motion blur during video capture by dynamically adjusting the exposure used to capture the video based on user motion. For example, exposure may be reduced to reduce the amount of blur during motion. Since such a reduced exposure captures a lesser amount of light, gain may be increased such that the captured video maintains a relatively constant image brightness in spite of the changing exposure over time.

Abstract: Various embodiments disclosed herein include techniques for determining autofocus for a camera on a mobile device. In various instances, a depth imaging system (e.g., a time-of-flight autofocus system (ToF-AF system)) is used to determine distance of a subject in order to determine autofocus for a camera. In some instances, however, the ToF-AF system may be unable to detect a subject that is very close to the camera when the objects are below a minimum detectable distance of the ToF-AF system. In such instances, an existing IR detector outside of the ToF-AF system may be implemented to measure reflected signals from the ToF-AF system. A power ratio may be determined from the reflected signals and used to determine information about the distance of the subject from the camera.
