An imager acquires a scene's image by pixels each of which has a digital storage device which accumulates information on a pertinent portion of the image. During image acquisition, the imager moves relative to the scene, and the contents of the digital storage devices are shifted from one pixel to another. In some embodiments, less than all bits of a digital storage device are shifted, and/or the shift is accompanied by some operation on the contents of the digital storage devices. Other features are also provided.
