Title
(JA) 撮像装置及び撮像装置の合焦制御方法
Abstract
(JA)

AFを高速化できる撮像装置及びその合焦制御方法を提供する。フォーカスレンズ(12)を駆動するフォーカスレンズ駆動部(16)と、イメージセンサ(110)を光軸(L)に沿って移動させるイメージセンサ移動駆動部(120)と、を備える。被写体に合焦させるためのフォーカスレンズ(12)の目標位置を設定し、目標位置に向けてフォーカスレンズ(12)を移動させる。フォーカスレンズ(12)が目標位置に到達する前にイメージセンサ(110)を移動させて合焦させる。合焦後は、フォーカスレンズ(12)に追従するようにイメージセンサ(110)を移動させて合焦状態を維持する。
