Stereoscopic imaging device and stereoscopic imaging method

摘要

A stereoscopic imaging device, wherein the aperture controller performs a second aperture control in which the larger the amount of shake detected by the shake detector becomes, the further the amount of opening of the aperture unit decreases than the amount of opening required for the first aperture control. The present invention allows to deepen a depth of focus and decrease the amount of parallax by further closing an aperture as the amount of shake becomes larger, so that a stereoscopic effect is weakened when the amount of shake is large, thereby reducing an influence on viewers.

主权项

1. A stereoscopic imaging device, comprising:
an imaging element that outputs a pair of images having a parallax, by pupil-dividing a light flux from an object into two light fluxes and imaging the two light fluxes onto two photoelectric conversion element groups corresponding to each flux to photoelectrically convert the two light fluxes; an aperture that adjusts an amount of light flux imaged onto the photoelectric conversion element groups of the imaging element; a light-quantity detector detecting the amount of light flux; an aperture controller capable of performing a first aperture control controlling an amount of opening of the aperture so that a desired parallax is obtained according to the amount of light detected by the light-quantity detector; and a shake detector detecting an amount of shake of an object image at a time of photographing an image by the imaging element, wherein the aperture controller performs a second aperture control in which the larger the amount of shake detected by the shake detector becomes, the further the amount of opening of the aperture decreases than the amount of opening required for the first aperture control.
