Abstract:
1. A stereoscopic imaging apparatus comprising: a single photographic optical system; an image sensor, on which subject images that have passed through different first and second areas in a predetermined direction of the photographic optical system, respectively, are formed after being pupil-split, configured to photoelectrically convert the subject images that have passed through the first and second areas, respectively, to output a first image and a second image; a diaphragm configured to restrict a light flux incident on the image sensor; a subject information acquiring device configured to acquire distance information of a subject within a photographic angle of view or a device configured to acquire an amount of parallax of the subject; and a diaphragm control device configured to set an F-number of the diaphragm so that a parallax between the first image and the second image is in a predetermined range based on the acquired distance information of the subject or the acquired amount of parallax of the subject, wherein the diaphragm control device determines the F-number of the diaphragm in accordance with the distance information of a nearest subject or a main subject within the photographic angle of view so that a shorter a distance represented by the distance information is, a larger the F-number becomes and a longer the distance is, a smaller the F-number becomes.
