A method and apparatus for processing a plurality of images. The method includes receiving or generating by an information processing apparatus the plurality of images. The plurality of images are stored in a memory, and separated into a plurality of image units. Sequence identifiers are assigned to the plurality of image units, and a first subset of the plurality of image units is processed by the information processing apparatus. The method further includes dividing the unprocessed plurality of image units into at least one second subset of the plurality of image units, and sending each of the at least one second subset of the plurality of image units to a different information processing apparatus for processing.
