1. A method of operating an electronic imaging device, comprising: acquiring luminance data of a succession of image frames of an object scene, normalizing the luminance data of the individual acquired image frames, utilizing the normalized luminance data to calculate estimates of motion of the object scene between successive frames, and utilizing the acquired luminance data of the image frames without the normalization for processing and storage in a manner that image frames are reconstructable from the stored luminance data, wherein the motion estimate is used to either control the acquisition of the data of the image frames or the processing of the data of the image frames or both.
