ABSTRACT:
An image mixing circuit usable in a video camera for mixing images with a continuous gradation characteristic in both the luminance signal and color signal is provided according to the present invention. A color separation circuit separates plural image signals into plural luminance signal components and plural color signal components. A control signal generation circuit then generates the control signal needed for image synthesis from the plural image signals. A luminance signal mixing circuit and a color signal mixing circuit then separately mix the respective luminance signal components and color signal components according to the control signal.
