ABSTRACT:
An image sensing apparatus includes a diaphragm for an image sensing optical system, the aperture of the diaphragm being formed in a shape which is substantially asymmetrical in a horizontal or vertical direction, a in-focus detecting circuit for making a decision as to near focus state, in focus and far focus on the basis of a signal waveform which corresponds to an edge portion of a subject image passed through the diaphragm, and a driving circuit for performing focus adjustment of the image sensing optical system on the basis of an output of the in-focus detecting circuit.
