Abstract

An image pickup apparatus has only a few line memories (5, 6, 7), a change-over switch (4, 104) for selectively supplying input signals to the line memories and a selector (8, 108) for selectively taking data stored in the line memories and stores data of a desired part of the picture to be enlarged or reformed in accordance with a predetermined procedure, and interpolation of the stored data of the scanning lines is sequentially performed, thereby enlarging or reforming the desired part of the picuture without lowering quality of the image.
