A METHOD AND APPARATUS FOR PRODUCING A VIDEO STREAM

摘要

A method of processing a stream of images comprises obtaining an image of a scene with a relatively short exposure time (SET) and obtaining an image of the same scene with a relatively longer exposure time (LET). Motion blur characteristics for the SET image corresponding to motion within the LET image are determined and the motion blur characteristics are applied to the SET image. The blurred SET image and the LET image are blended to provide a HDR image. The process is repeated for successive pairs of images in the stream to provide a sequence of HDR images which can be encoded in a video stream.
