Abstract

PURPOSE:To achieve shrinking or modulation only a human body and an object and synthesis with other pictures, by making the similar signal processing as a chromakey sigal and a video signal and writing and reading them to the 2nd memory. CONSTITUTION:When a picture element is picked up from a consecutive picture element with a certain interval and the rest picture elements are written cramming in a memory, a shrinked picture is obtained at th output. As memories generating a key signal, two memories are used and even if readout is made from the memories repetitively within one frame, no key signal is cleared. (b) and (c) show an input data to the two memories, and a chromachy signal X and a signal key of ''0'' to clear the memories are inputted alternately. For example, the character ''A'' of the (b) is picked up with the key signal of (c) and shrinked into (d) and (e). When (a) and (d) are synthesized with the shrinked chromakey signal, the character ''A'' only is shrinked and inserted as shown in (f).
