よつて撮像する撮像装置であつて、 撮像手段と光学系との相対距離を変化する駆動
手段を含み、 撮像手段は、光学像の撮像手段における結像状
態に関連するレベルの信号を出力し、 前記駆動手段による前記相対距離の変化後の撮
像手段からの信号のレベルと、変化以前の信号の
レベルとを比較し、撮像手段における結像状態を
識別するようにしたことを特徴とする撮像装置。[Scope of Claim for Utility Model Registration] An imaging device that captures an optical image of a subject by an imaging means via an optical system, including a driving means for changing the relative distance between the imaging means and the optical system; The means outputs a signal at a level related to the imaging state of the optical image imaging means, and determines the level of the signal from the imaging means after the relative distance is changed by the driving means and the level of the signal before the change. An imaging device characterized in that the image formation state in the imaging means is identified by comparison.
