Abstract:
System and methods for performing motion sensitive high dynamic range (HDR) image processing. A saturation analysis circuit is configured to receive a set of image data corresponding to portions of a set of image frames having different exposures time from a lowest exposure time to a highest exposure time, and select image data from a frame that does not exceed the saturation threshold value. A motion detection circuit may be configured to determine whether the image data is associated with movement, by comparing image data from pairs of frames of adjacent exposure times, and changing the selection to a lower exposure time frame if movement is detected. By selecting which exposure time is used based upon movement in the image frame, ghosting and blurring in HDR images containing movement can be reduced.
