Abstract:
A camera control device is provided with a determination device for dividing the image frame into plural areas including a central area and determining the object distance in each of the areas; a focal length detecting device for detecting the focal length of a phototaking lens; an eye-gaze direction detecting device for detecting the position of the eye-gaze of the user, corresponding to one of the areas of the image frame, thereby specifying the area desired by the user; a phototaking magnification calculating device for calculating the phototaking magnification in each of the areas, based on the output of the focal length detecting device and that of the determination device; and an area selecting device for selecting either the central area in case the phototaking magnification in the central area, calculated by the above-mentioned calculating device exceeds a predetermined value, or an area specified by the eye-gaze direction detecting device in case the above-mentioned predetermined value is not exceeded.
