Stereoscopic imaging apparatus

A stereoscopic imaging apparatus comprising:

• a first imaging section and a second imaging section for imaging an object, and a controlling section for controlling the first imaging section and the second imaging section to obtain a stereoscopic image, a main optical system which is a photographing optical system shared by the first imaging section and the second imaging section;
• and a beam splitter of a mirror or a prism for splitting luminous fluxes having passed through the main optical system,
• wherein the first imaging section and the second imaging section respectively has an imaging optical system for imaging the luminous fluxes split by the beam splitter and an image sensor which includes a plurality of pixel groups for photo-electrically converting the luminous fluxes having passed through different regions of the imaging optical system for each of the pixel groups, and
• the controlling section has a function of double-eye stereoscopic photography in which a viewpoint image obtained by the first imaging section and a viewpoint image obtained by the second imaging section are recorded to a recording medium as the stereoscopic image, and a function of single-eye stereoscopic photography in which a plurality of viewpoint images obtained by the imaging section which includes the plurality of pixel groups among the first imaging section and the second imaging section is recorded to the recording medium as the stereoscopic image.
