An image signal representing consecutive video frames is resampled, using different sampling phases so that different subsets of pixels are taken from each frame in a consecutive set of frames. The resulting set of resampled frames is combined into a single frame and transferred to an image display unit that divides the single frame into subframes and displays the subframes sequentially with different pixel shifts. Each pixel in each subframe is displayed at its correct spatial and temporal position. Although the resampling process greatly reduces the pixel data transfer rate, the image display unit can reproduce still images without loss of definition and moving images without motion blur.

Image processing devices utilize computationally efficient operations based on exposure time and object speed to detect and estimate motion blur. These operations include determining, from a plurality of image frames of an object, a representative length of movement associated with at least one feature point of the object, which undergoes movement between the plurality of image frames. This representative length of movement is converted to an estimate of motion blur for a respective image frame, using operations that are function of length of movement and exposure time.
