摘要：
A photographic optical system controlling apparatus for carrying out an automatic focusing control and an exposure control. The apparatus comprises a motion vector detecting means for detecting the motion of the image and changes a gate area or a photometric area. The result is that the focusing or the exposure controlling operation can be carried out accurately following the motion of a main object, irrespective of the positional change of the object the screen.
