ABSTRACT:
A chromakey effect apparatus including a color-killing subcarrier-generating circuit which generates a color-killing subcarrier which completely kills color even when the hue or saturation of the chromakey area is changed and which also kills the color while simultaneously converting the color. Furthermore, the apparatus is capable of both chromakeying only the chromakey area even when there are many portions having the same color as the chromakey area, and also chromakeying a desired portion even when the desired portion includes a part having different colors. In addition, the apparatus is capable of inserting another television signal into only a desired portion of the chromakey area and of converting the color of the remaining portion of the chromakey area.
