Camera and method 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

摘要

The present invention relates to a method and camera 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. This is made by: determining, based on image data from a plurality of image sensor frames, regions of the scene comprising different level of motion; determining image frame regions for said image frame, wherein an image frame region corresponds to at least one region of the scene; and optimizing the exposure of the image frame 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, wherein 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.
