Abstract
A stereoscopic image pickup system for obtaining parallactic images includes a pair of front optical components, the pair of front optical components respectively including a pair of reflecting members capable of rotating around respective predetermined axes and having a reflecting function, and a pair of amount-of-light control members arranged to respectively vary amounts of transmission of light fluxes coming from the pair of reflecting members alternately in a time-series manner, an optical member arranged to superpose respective optical axes of the pair of front optical components on each other, a rear optical component having an optical axis coinciding with the superposed optical axes of the pair of front optical components and having a magnification varying function, and a controller for controlling an amount of parallax of parallactic images by using the pair of reflecting members in accordance with a magnification varying operation of the rear optical component.
