Description
上記目的を達成するために、本発明にかかる撮像装置は、動画撮影が可能な撮像装置であって、被写体の輝度値を取得する輝度値取得手段と、絞り値、電荷蓄積時間、撮影感度の少なくとも1つを制御して露出制御を行う露出制御手段と、を有し、前記露出制御手段は、動画撮影を開始する前に前記輝度値取得手段により取得された輝度値、予め決められた所定の電荷蓄積時間及び予め決められた所定の撮影感度に基づいて動画撮影開始時の絞り値を設定し、動画撮影中に輝度値が変化した場合、絞り値よりも電荷蓄積時間及び撮影感度を優先的に変更させて前記露出制御を行うことを特徴とする。 In order to achieve the above object, an imaging apparatus according to the present invention is an imaging apparatus capable of shooting a moving image, and includes a luminance value acquisition unit that acquires a luminance value of a subject, an aperture value, a charge accumulation time, and a shooting sensitivity. Exposure control means for controlling exposure by controlling at least one of the exposure control means, the exposure control means, the brightness value acquired by the brightness value acquisition means before starting moving image shooting, a predetermined predetermined value If the aperture value at the start of movie shooting is set based on the predetermined charge accumulation time and the predetermined shooting sensitivity, and the brightness value changes during movie shooting, the charge accumulation time and shooting sensitivity have priority over the aperture value. to be changed and performs the exposure control.
