Description

本発明の一態様によると、撮像装置は、絞りを有する光学系を介して入射した光を撮像して信号を出力する撮像部と、前記信号に基づく画像データを記録するために前記撮像部が撮像を行う間の第１絞り値が、前記信号に基づく画像を表示部に表示するために前記撮像部が撮像を行う間の第２絞り値よりも大きく、前記第１絞り値と前記第２絞り値との差が第１の値より大きくなると、前記第２絞り値を前記第１絞り値に基づいて変更する第１制御を行う制御部と、を備える。 According to one aspect of the present invention, the imaging device includes an imaging unit that images incident light through an optical system having an aperture and outputs a signal, and an imaging unit that records image data based on the signal. The first aperture value during imaging is larger than the second aperture value during which the imaging unit performs imaging in order to display an image based on the signal on the display unit, and the first aperture value and the second aperture value are larger than the second aperture value during imaging by the imaging unit. and a control unit that performs first control to change the second aperture value based on the first aperture value when the difference between the aperture value and the aperture value becomes larger than the first value.
