Enhanced video capture in adverse lighting conditions

摘要

A device and method of capturing a video frame using an electronic device to provide enhanced video. A first sub-frame is captured using ambient light, and a second sub-frame is captured using ambient light and a light source under control of the electronic device. A primary frame is generated based on a combination of the first sub-frame and the second sub-frame.

1. A method of capturing a video frame using an electronic device, comprising:
capturing a first sub-frame using ambient light; capturing a second sub-frame using ambient light and a light source under control of the electronic device; and generating a primary frame based on a combination of the first sub-frame and the second sub-frame, said generating including comparing, on a pixel-by-pixel basis, pixels of the first sub-frame with corresponding pixels of the second sub-frame; for each comparison, flagging one of a pixel of the first sub-frame or a pixel of the second sub-frame that satisfies a predefined characteristic; and using the pixels flagged in the first sub-frame and the pixels flagged in the second sub-frame to generate the primary frame.
