Abstract
PURPOSE:To generate a key signal of a sufficient level and to erase the fog of selected colors to an object by being respectively equipped with a first color selecting circuit for generating the key signal and a second color selecting circuit for erasing colors. CONSTITUTION:By I and Q components converted by a matrix circuit 2, the color of a B point is made to a central hue, a color selection is executed with the color of a solid oblique line part as a color selecting area by a first color selecting circuit 3 and the key signal is generated by a key signal forming circuit 4. The color selection of a dotted oblique line part is executed by a second color selecting circuit 3a and by executing the color erasing of this area by a color erasing circuit 5, a hue changing part among A-B-C is completely color-erased. Thus, the fog is not generated on a composite picture.
