Video system having image combining function
First Claim
1. A video system, comprising:
- (a) an auxiliary unit including a memory for storing image data corresponding to an area occurpying a portion of one picture and location data indicative of the location of the image data in the one picture; and
(b) a primary unit to which said auxiliary unit is removably secured, the primary unit including inputting means for inputting a first video signal, memory means for storing the image data, forming means for forming a second video signal by reading out the image data from said memory means at a timing according to the location data, and combining means for combining the first video signal with the second video signal.

Abstract
A video system is constructed of an auxiliary unit and a primary unit. The auxiliary unit includes a memory 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 includes an inputting circuit for inputting a first color video signal, a forming circuit 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 and a combining circuit for combining the first video signal with the second video signal. The video system is capable of producing a variety of comined images with a relatively small memory capacity.
