摘要： A head tracking stereoscopic display has a first combining light source composed of two line-shaped light sources and a second combining light source composed of two line-shaped light sources. The first combining light source is used when the head of a viewer is shifted by the distance between the eyes E in the horizontal direction on the basis of a certain position, and the second combining light source is used when the head of the viewer is shifted by the distance between the eyes E in the horizontal direction on the basis of a position shifted by E/2 from the certain position. When the first combining light source is selected, the two line-shaped light sources in the first combining light source are alternately turned on and off. When the second combining light source is selected, the two line-shaped light sources in the second combining light source are alternately turned on and off. A right eye image and a left eye image are alternately displayed in synchronization with the alternate ON/OFF on an image display panel. Such control as to change the timing at which images are alternately displayed and such control as to select the combining light source are suitably carried out on the basis of information relating to the head position from the head position detection means.

摘要： The system and the method are intended to enable robots, devices, tools, etc., to see the environment in which they operate, by means of a pair of identical cameras, aligned, compatible and coordinated with their fields of sight (photographing) being parallel and adju sted in parallel divergence (M) between each and every line in the fields of sight, and to identify anything viewed by the cameras immediately and at the rate of photographing/filming. By means of the system and the method, the computer vision receives the pictures from the cameras into a designated place for this purpose and a backup is created for the field of sight from the pictures stored in the spatial-memory, and it calculates the distance for each and every point in the picture, as well as the dimensions of the shapes and registers their various features. The system includes a memory register for movement identification at time intervals and calculation of movement, motion, speed and direction of each and every shape in the pictures of the leading camera, received after color filtering, a register of basic shapes and data table(s) such as the "true" table. Said registers are meant for purpose of detecting data, features, definitions and for drawing of conclusions for the key elements. The data, the features, definitions and conclusions enable to compose keys for the unidentified shapes, compatible with the recognized stored shapes register, and thus identification of the unidentified shapes is carried out fully and almost immediately.

摘要： Space correction processing is performed for correcting an error between the position of actual space and the position of space which has been detected by a position sensor and can serve as a virtual space (Step 100). Processing for setting the position of a screen is performed for accurately ascertaining the three-dimensional position of an image which is displayed on a screen 16 (Step 102). Processing for setting the position of a visual point is performed for setting the position of an actual visual point of an operator OP (Step 104). Consequently, the position of the visual point and a position on the screen can be inputted accurately, and a highly accurate stereoscopic image is displayed in the virtual stereoscopic space faithfully to a real object by adopting the set screen position and the position of the visual point in the virtual space subjected to spatial correction (Step 106).

摘要： A hybrid driving arrangement of multiple 3D graphics renderers and multiple synthetic stereo processors is provided for driving multiple view displays such as four view display devices. The device is an LCD screen device with an overlying lenticular screen, with the arrangement of pixels driven from the four different sources relative to the individual lenticular arrays being such that, at viewing locations V1 to V4, the images from respective ones of the four sources (76-79) can be seen. As the main viewer of such a multiple view display will typically be positioned in the center of the display as shown, and as such will only see a stereoscopic image provided by the two central views V2 and V3, the image sources for the two center views V2,V3 are respective 3-D graphics renderers, and those for the other views, post-processing stages. Thus the main viewer has the best quality view while viewers to the side suffer some (acceptable) degradation.

摘要： Rotating image data of a subject which is composed of two-dimensional image data for each predetermined angle of rotation of the subject is stored in storing means. Reference image data and image data delayed from the reference image data are selected out of the two-dimensional image data for each predetermined angle of rotation of the subject which are stored in the storing means, and are successively read out. One of the reference image data and the delayed image data which are read out is outputted as a left eye image signal, and the other image data is outputted as a right eye image signal.

摘要： The generation of a stereoscopic image by means of two cameras and a considerably amount of circuitry is known. The aim here is to provide an arrangement which can produce a stereoscopic image simply and cheaply. An optical unit (1) views an object (O) and a stereoscopic image is produced on a recording or display device (4) by differently polarising the polarisation units (2, 3) of the beams. Especially for videophones.

摘要： An image pickup system mounted on a craft flying an orbit above an object zone and sequentially picking up the images of unit areas defined by the swath width of the object zone and a distance in the direction of orbit. the system has a main image pickup device and a control image pickup device for picking up the image of an area ahead of the visual field of the main pickup device, i.e., a forward area preceding the unit area. While the craft flies along the orbit, the control image pickup device detects the. radiance distribution of the forward area to thereby control, for example, the sensitivity of the main image pickup device. To detect the radiance distribution, a data processing section included in the control pickup device converts data picked up in the forward area to an image to allow the image to be compared with predetermined reference values.

摘要： A stereoscopic graphics display system (10) has a stereoscopic window controller (18) that generates multiple windows (72 and 74) within which multiple images (76 and 78) are formed. The stereoscopic window controller directs the graphics displays system to render around each window a border (80 and 82) representing an outline of the window. Each of the borders is rendered with zero binocular disparity to assist an observer to perceive the three-dimensional qualities of stereoscopic images. Depth cue contradictions between stacked windows are reduced by rendering with zero binocular disparity the images in occluded windows.
