In some embodiments, a stereoscopic imaging apparatus includes a tubular housing having a bore extending longitudinally through the housing. First and second image sensors are disposed proximate a distal end of the bore, each including a light sensitive elements on a face and mounted facing laterally outward. The apparatus further includes a first beam steering element associated with the first image sensor and a second beam steering element associated with the second image sensor. The beam steering elements receive light from first and second perspective viewpoints and direct the received light onto the faces of the image sensors forming first and second images. Either the first and second beam steering elements or the first and second image sensors are moveable to cause a change a spacing between or an orientation of the perspective viewpoints to cause sufficient disparity between the first and second images to provide image data including three-dimensional information.

An image acquisition apparatus includes a color filter on which a plurality of types of color filter elements are arranged, an optical path modulation optical element configured to shift an incident position of an image on the color filter by electrically modulating an optical path of the image, and a photoelectric conversion cell array configured to acquire image information for each color by detecting, in pixel units, light which has passed through the color filter. A color image is obtained by acquiring, in a time division manner, the image information for each color of the image of which a position is changed by the optical path modulation optical element by using a detection signal of the photoelectric conversion cell array, and combining the acquired image information for each color.
