PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of photographing a subject, which may change at each timing of interval photography, in an in-focus state even if the subject moves.SOLUTION: An imaging apparatus 100 comprises an optical unit 102 and an imaging element 104, and performs interval photography at intervals of set time. A distance map information acquisition part 113 acquires distance map information, representing a depth-directional depth of each subject in a captured image, at each timing of photography. A distance map comparison part 114 compares distance map information of different photography time to detect whether distance information has change. A CPU 101 performs focus adjustment control over an optical unit 102 according to position information in an image corresponding to change of the distance information if the distance map comparison part 114 detects the change of the distance information.SELECTED DRAWING: Figure 1 【課題】被写体が動いた場合でも、インターバル撮影のタイミングごとに変化し得る被写体に焦点を合わせた撮影が可能な撮像装置を提供する。【解決手段】撮像装置１００は光学ユニット１０２および撮像素子１０４を備え、設定された時間間隔でインターバル撮影を行う。距離マップ情報取得部１１３は、撮像された画像内の各被写体の奥行き方向の深さを示す距離マップ情報を撮影時刻ごとに取得する。距離マップ比較部１１４は、異なる撮影時刻の距離マップ情報を比較し、距離情報に変化があるかどうかを検出する。ＣＰＵ１０１は、距離マップ比較部１１４により距離情報の変化が検出された場合、当該変化に対応する画像内の位置情報に応じて、光学ユニット１０２の焦点調節制御を行う。【選択図】図１
