Patent ID: 8160440

Claim:
A three-dimensional image pickup apparatus for capturing a three-dimensional image which includes a left-eye image and a right-eye image, the three-dimensional image pickup apparatus comprising: a first imaging unit having a first optical system and operable to take the left-eye image; a second imaging unit having a second optical system and operable to take the right-eye image; and a controller operable to control the first imaging unit and the second imaging unit, wherein: the first optical system and the second optical system individually include a convergence angle changing unit capable of optically changing a convergence angle and a focal length changing unit capable of optically changing a focal length; and the controller, when controlling the focal length changing unit to change the focal length, controls the convergence angle changing unit based on a predetermined constant convergence angle tracking curve to keep the convergence angle constant before and after the change of the focal length.
