    • In a stereoscopic television display device, the timing of read out data of a frame memory for right eye and the timing of read out data of a frame memory for left eye are shifted with respect to each other other so that the observer can freely select a point other than a camera's observation point as his observation point. Furthermore, according to another aspect of the invention, a stereoscopic television image pickup device is provided in which an electrically controllable aperture and an optical transmission plate having an electrically controllable transmittance are disposed between an object and image pickup units for right eye bad left eye, and in each image pickup unit the aperture and the transmittance are controlled so that the video signal level and the degree of opening of the aperture are set to desired values.

    • A method and apparatus for obtaining a stereo image with reduced depth distortion and optimum depth resolution. Static and dynamic depth distortion and depth resolution trade-off is provided. Cameras obtaining the images for a stereo view are converged at a convergence point behind the object to be presented in the image, and (a) the collection-surface-to-object distance, (b) the camera separation distance, and (c) the focal lengths of zoom lenses for the cameras are all increased. Doubling the distances cuts the static depth distortion in half while maintaining image size and depth resolution. Dynamic depth distortion is minimized by panning a stereo view-collecting camera system about a circle which passes through the convergence point and the cameras' first nodal points. Horizontal field shifting of the television fields on a television monitor brings both the monitor and the stereo views within the viewer's limit of binocular fusion.

    • Surface segmentation from RGB and depth images is described. In one example, a computer receives an image of a scene. The image has pixels which each have an associated color value and an associated depth value representing a distance between from an image sensor to a surface in the scene. The computer uses the depth values to derive a set of three-dimensional planes present within the scene. A cost function is used to determine whether each pixel belongs to one of the planes, and the image elements are labeled accordingly. The cost function has terms dependent on the depth value of a pixel, and the color values of the pixels and at least one neighboring pixel. In various examples, the planes can be extended until they intersect to determine the extent of the scene, and pixels not belonging to a plane can be labeled as objects on the surfaces.

    • A three-dimensional vision camera where there is no disagreement between the video signal and the distance signal is provided by using the taking optical system for the distance measurement. A reflecting mirror 8 for reflecting a distance measuring laser beam from a laser diode 6 is arranged behind a taking lens 4. The laser beam is irradiated to a photographic object through the taking lens 4. The laser beam reflected by the photographic object is received by a photodiode array 7 through the taking lens 4 and the reflecting mirror 8. While the taking lens 4 is moved along the optical axis to perform photographing, the laser scanning is performed by rotating the reflecting mirror 8 about two axes vertical to the optical axis of the taking lens 4 to measure the distance.
