摘要

An image capture apparatus (100), comprising: a photographic optical system (21) intended to project an image of an object; an imaging device (24) intended to convert the projected image into an image signal and to deliver it at its output; a focus control device (25) that changes a focus situation of the projected image on said imaging device (24) by the relative movement of at least one of a part or all of said photographic optical system ( 21) and said imaging device (24) towards the other; a first autofocus device (82) that sequentially evaluates said image signal obtained in each focus situation while subsequently changing said focus situation by controlling said focusing command device (25), and obtaining a situation default approach based on evaluation; a control device (83) intended to control an operation of said first autofocus device (82), and a distance measuring device (31) intended to measure a distance of the object that is the distance from said object, characterized in that said distance measuring device (31) measures the distance from each of a plurality of different areas of said object, respectively, and said control device (83) controls the operation of said first autofocus device (82) according to the difference between a maximum value and a minimum value of said measured distances obtained by said distance measuring device (31) in order to give priority to either focus accuracy or focus speed.
