发明名称 Video signal processor for detecting flesh tones in an image
摘要 A flesh-tone area is detected based on color-difference and luminance signals constituting video signals, and luminance correction, color correction, and aperture correction are performed only on the flesh-tone area or a human face area identified in the flesh-tone area. The setting of a focus area or the setting of a photometric area for iris control, automatic gain control, automatic shutter control, etc., in a video camera, is performed with respect to the flesh-tone area or the human face area. Furthermore, based on the color-difference and luminance signals constituting the video signals, a background area is detected, and the video signals are divided into components representing a background area and components representing an object area. An image signal of a desired hue or a still image is superimposed on the detected background area, or special processing is performed on the video signals representing the object area other than the detected background area.
