GRAPHISCHE FARBPALETTENVORRICHTUNG UND VERFAHREN DAFUER

摘要

A self-palette graphic apparatus is provided to use an arbitrary display portion as a palette 10, so that a colour may be selected from the representation of a current graphic image on a monitor. This apparatus recognizes coordinate values from a stylus pen 100 placed on a desired colour, as well as the coordinate values of a currently displayed video signal. If they coincide with each other, a sampling control signal is generated so as to sample 170 the currently displayed video signal. Each colour component is separated 180 from the sampled video signal and is processed in a controller 130. <IMAGE>
