Abstract
An automatic focus adjusting apparatus for automatically adjusting a focus condition of an objective lens, the automatic focus adjusting apparatus repetitively effecting focus detection, in-focus judgement, and lens driving. If the lens cannot be regarded as being in focus as a result of a standard focus detection, then on the one hand, when the deviation from the in-focus point is small, lens driving is effected and in-focus is judged to quickly arrive at a judgement of in-focus, and on the other hand, when the deviation from the in-focus point is large, a judgment of in-focus based on the deviation from the in-focus point being small is inhibited to thereby enable the lens to be fully driven and a standard in-focus judging operation to be accomplished.
