A stereoscopic image pickup apparatus includes a first imaging section, a second imaging section, a zoom controller, and an image selection section. The first imaging section includes a zoom lens. The second imaging section includes a zoom lens. The zoom controller controls angles of view of the zoom lenses of the first imaging section and the second imaging section. The image selection section outputs image signals, which are output by the first imaging section and the second imaging section, as image signals of two channels constituting a stereoscopic image when the angles of view controlled by the zoom controller are equal to or greater than a predetermined value. In addition, the image selection section outputs image signals, which are based on the image signal output by either the first imaging section or the second imaging section, as the image signals of two channels constituting the stereoscopic image when the angles of view controlled by the zoom controller are less than the predetermined value.
