An stereoscopic optical system includes two parallel optical systems arranged in parallel for a single common image sensor. Each optical system has an angle of view in which an image of another optical system is formed in a first area at an outer peripheral portion in an image circle, and includes a field stop in a second area at an inner peripheral portion in the image circle. A distance between centers of the image circles of the two optical systems is shorter than a diameter of each image circle on the image sensor, and at least part of each first area is located outside the image sensor.

The present technology relates to an information processing apparatus, an information processing method, and a program as well as an interchangeable lens that make it possible to easily obtain an image of a plurality of visual points. A communication section receives, when an interchangeable lens including monocular lenses that are plural lenses arranged so as not to overlap with each other in an optical axis direction is mounted on a camera main body that includes an image sensor, known reference positions that are positions on a captured image on which a predetermined imaging target imaged by the image sensor appears, the positions corresponding to predetermined rays of light on monocular images corresponding to figures formed from rays of light focused by the monocular lenses. A reference position calculation section determines unknown reference positions on the basis of the known reference positions. The present technology can be applied to a camera system for capturing an image.
