Abstract

　一眼レフデジタルカメラカメラにおいて、フォーカスレンズ群を超音波アクチュエータによりリニア駆動し、コントラスト検出方式のフォーカスを行うカメラシステムを提供する。 　フォーカスレンズ群と超音波アクチュエータをフォーカスユニットとして構成し、フォーカスレンズ群をガイドポールにより支持し、超音波アクチュエータによりリニア駆動する。フォーカスレンズユニットは、ズームカム環と機械的に連結することにより、ズーム操作により、光軸方向の所定位置に移動可能な構成とする。オートフォーカス時には、撮像素子によりコントラスト検出を行うことにより、コントラストピークを求め、電子制御方式にて、フォーカスレンズ群を所定位置に移動させ、フォーカス調整を行う。
