ABSTRACT:
An image sensing apparatus operating with adaptive selection of a first tracing algorithm in which an object image is traced by moving a detecting area capable of being movably set on an image sensing plane in such a manner that the luminance level difference between the inside and the outside of that area becomes maximum and a second tracing algorithm in which the object image is traced by moving the position of the detecting area in such a manner that a point at which a contrast becomes maximum comes to coincide with a central portion of the detecting are depending on the state of the image sensing plane. The threshold values for changing over between the first tracing algorithm and the second tracing algorithm are made to have a hysteresis characteristic.
