ABSTRACT:
A video camera system having a camera (128) and an interchangeable lens assembly (127) attachable to and detachable from the camera. A distance measurement frame is set by a distance measurement frame controller (129) on photographer's line-of-sight position information detected by line-of-sight detecting units (135to140), and a focal-point evaluation value is extracted by an AF signal processing circuit (113) from an image signal corresponding to the distance measurement frame. The line-of-sight position information, focal-length evaluation value, etc, are transmitted to the lens assembly (127). A zoom lens (102) and focusing lens (105) are controlled by the lens assembly (127).
