ABSTRACT:
The present invention relates to an automatic focusing apparatus for positioning a lens at the optimum focus position. The apparatus includes an image pick up element which can be accessed at any desired line, thus allowing only a predetermined portion of an image pickup plane to be read scanned. This enables plural AF scan operations to be performed at high-speed.
