1. A system for forming an image from a stream of non-interleaved rows of pixels, the system comprising A. a host device that includes a host memory having a plurality of addressable storage locations in which the image is to be stored, the host device specifying respective locations of the host memory into which successive rows received from the stream are to be stored, B. image acquisition logic that is coupled to the host device, the image acquisition logic including a controller for at least initiating a plurality of memory transfers, each memory transfer for storing a respective row of pixels in a respective location in the memory specified by the host device, and C. the controller initiating the transfers such that (i) the rows of pixels are transferred to the host memory substantially in an order in which they are received from the stream, and (ii) the rows of pixels are transferred substantially directly to locations in the host memory corresponding to relative positions of those rows in the image.
