Interleaved capture for high dynamic range image acquisition and synthesis

摘要

A computing device may capture a first image using a first exposure length. It may be determined that x pixels in the captured first image are properly-exposed and that y pixels in the captured first image are improperly-exposed. Based on the y improperly-exposed pixels, a second exposure length may be determined. A second image may be captured using the second exposure length. The second image may include y′ pixels that correspond to the y improperly-exposed pixels in the first image. At least some of the x properly-exposed pixels from the first image may be combined with at least some of the y′ pixels from the second image to form a composite image.
