<p>PROBLEM TO BE SOLVED: To prevent occurrence of a defect of a blur image in performing imaging using an electronic front curtain method.SOLUTION: An imaging device comprises: light shading means for shading an imaging element from light; judgment means for judging whether or not magnitude of a blur image of a subject exceeds predetermined magnitude, on the basis of at least one of a focal distance of an imaging optical system, an imaging distance to a main subject, and difference between an imaging distance of the main subject and that of the subject; determination means for determining a combination of a diaphragm value and exposure time in which a defect occurs in the blur image, when it is judged that the magnitude of the blur image of the subject exceeds the predetermined magnitude; setting means for setting an imaging diaphragm value and imaging exposure time, according to the determined diaphragm value and exposure time; exposure control means for controlling exposure time by using the imaging exposure time by making the light shading means shade the imaging element after making the imaging element start accumulating electric charge; and diaphragm control means for controlling diaphragm drive by using the imaging diaphragm value.</p> |
