摘要： A three-dimensional image pickup apparatus for capturing a three-dimensional image which includes a left-eye image and a right-eye image includes: 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. 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. 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.

摘要： A photographic light is spectrally separated by a spectral prism 9 provided in an image-formation area R of the photographic light whose luminous flux is adjusted by a group of lenses 1a-1d for adjusting the luminous flux so as to image-form the photographic light. Respective lights spectrally separated by the spectral prism 9 are imaged by means of the imaging elements 2. An infrared-ray element of the photographic light whose luminous flux is being adjusted is eliminated by an infrared-ray cut filter 8. The infrared-ray cut filter 8 is advanced and retreated by a mechanism unit 14a between a position in an optica path of the photographic light and a position distant from the optical path. In the foregoing constitution, the infrared-ray cut filter 8 and the mechanism unit 14a are disposed in a luminous flux convergence area R of the photographic light whose luminous flux is being adjusted by the group of lenses 1a-1d.
