Abstract

　カメラシステムにおいてモニタ撮影モードの利便性を高める。カメラシステム（１）は交換レンズ（２）とカメラ本体（３）とを有している。カメラ本体（３）は、撮像部（７１）と、コントラスト検出ユニット（３１）と、焦点ずれ量検出ユニット（５）と、ボディーマイコン（１２）と、を有している。コントラスト検出ユニット（３１）は、撮像部（７１）により取得された被写体の画像信号からコントラスト値を検出し、コントラスト値に基づいて光学像の合焦状態を検出する。焦点ずれ量検出ユニット（５）は、位相差検出方式により光学像の合焦状態を検出する。ボディーマイコン（１２）は、交換レンズ（２）側のレンズ情報に基づいて、コントラスト検出ユニット（３１）および焦点ずれ量検出ユニット（５）のうち一方を選択する。
