摘要:
A gain may be applied to a short-exposure image to form a virtual long-exposure image. The short-exposure image may have been captured using a short total exposure time (TET), the virtual long-exposure image may have a virtual long TET, and the virtual long TET may be greater than the short TET. A true long-exposure image may be captured using a true long TET. The true long TET may be substantially equal to the virtual long TET. Color values of at least some pixels of the true long-exposure image may be copied to corresponding pixels of the virtual long-exposure image.
