ABSTRACT:
Separate portions of an image are identified as distinct areas, each of which is identified by a code. Coded signals representing lines extending in one direction across the image are read out of a first store under the control of clocking signals in serial form at a given clock rate to expand or compress the image in one direction. The signals are fed out via an averaging circuit which improves the picture definition and they are fed into a second store. The signals are then read out of the second store in serial form and under the control of clock pulses via a second averaging circuit which improves the picture definition by scanning in lines extending in a second direction to compress or expand the image in a second dimension.
