ABSTRACT:
A video camera system with autonomous target tracking sets a measuring frame on an object with high accuracy using a hue signal and a brightness signal without being affected by intensity and direction of the light source. A display screen is divided into divided areas and for each divided area, a lightness divided area in which the values of the brightness signal are within prescribed ranges of luminance and a skin color divided area in which the values of the hue signal are within prescribed ranges corresponding to skin color are extracted. Based on the extraction result, the position of the object on the screen determined and the measuring frame is set without being affected by intensity and direction of the light source. Thereafter, the object is continuously centered within the measuring frame.
