Abstract
Abstract The video system is constructed of an auxiliary unit (8) and a primary unit (1). The auxiliary unit (8) includes a memory (9) for storing a plurality of image data corresponding to an area occupying a portion of one picture, a plurality of location data indicative of the respective locations of the plurality of image data in the one picture and a plurality of color data indicative of respective colors relative to the plurality of image data. The primary unit (1) includes an inputting circuit (4) for inputting a first color video signal, a forming circuit (15) for forming a second color video signal according to the plurality of image data, the plurality of location data and the plurality of color data which are supplied from the auxiliary unit (8) and a combining circuit (5) for combining the first video signal with the second video signal. The video system is capable of producing a variety of combined images with a relatively small memory capacity.
