Abstract
A method and camera are used for optimizing the exposure of an image frame in a sequence of image frames capturing a scene based on level of motion in the scene. Based on image data from a plurality of image sensor frames, regions of the scene are determined including different level of motion. Image frame regions for the image frame are determined, wherein an image frame region corresponds to at least one region of the scene. The exposure of the image frame is optimized by emulating a region specific exposure time for each image frame region by producing each image frame region using image data from a number of image sensor frames. The number of image sensor frames used to produce a specific image frame region is based on the level of motion in the at least one corresponding region of the scene.
