    Abstract: An autostereoscopic display system comprised of an array of vertically oriented narrow light sources and a spatial light modulator, (SLM), disposed between the lights and viewers, whereby light rays originating from the lights and passing through the SLM are vertically dispersed by a vertical dispersion panel. The lights are sequentially flashed, sending light through the SLM where selected full height narrow vertical picture lines, VPL's, are made briefly transmissive while the remainder of the SLM remains dark, projecting vertically oriented sheets of light through selected VPL's toward selected eyes. The light sheets are sufficiently narrow as to enter a left or right eye but not both, while the entire height of selected VPL's is visible due to said vertical dispersion. The process rapidly repeats for all VPL's and all array lights, alternating between right/left SLM scenes each projected into appropriately selected eyes resulting in a 3D image.

  • Patent number: 8253780
    Abstract: An image display system for displaying interlaced images to achieve three dimensional effects. The system includes a user electronic device, such as a computer or television, with a display with a faceplate. The electronic device operates the display to generate an image that includes an interlaced portion at an inner display surface or location at an internal offset distance from an outer surface of the faceplate. The image display system includes a lens array with lenticules configured to focus through the lens array material, through an air gap, and into the faceplate the internal offset distance rather than simply on the back of the lens array. The display system may also include a mounting mechanism for selectively positioning the lens array relative to the faceplate to adjust the size of the air gap so as to focus the lens array onto the image being displayed within the display device.

    Abstract: In a three dimensional video display device (1), an LED unit (10) rotates in the direction of the arrow (24) along top and bottom edges of a display section (28). The LED unit (10) has a left-eye LED array (6) and a right-eye LED array (8), each including plural LEDs (4) aligned in a column. The left-eye LED array (6) displays a left-eye image through an afterimage effect produced by displaying, while rotating, columns of pixel groups constituting the left-eye image. The right-eye LED array 8 displays a right-eye image through an afterimage effect produced by displaying, while rotating, columns of pixel groups constituting the right-eye image. Light from the left-eye image enters the left eye of a viewer, whereas light from the right-eye image enters the right eye. The viewer recognizes a three dimensional image in a range of 360° around the viewer based on binocular parallax.

    Abstract: According to one embodiment, a video processor includes: an input module configured to receive a first image frame group in which an image capturing target is captured as a video image and a second image frame group in which the image capturing target is captured in the same timing as the first image frame group; an intermediate image generator configured to generate an intermediate image of continuous image frames in the first image frame group; a display controller; and a controller. The intermediate image generated by the intermediate image generator and the second image frame group are sequentially displayed alternately, and the intermediate image is seen in one part while the intermediate image is displayed and the second image frame group is seen in the other part while the second image frame group is displayed synchronously with the display controlled by the display controller.

  • Patent number: 7903139
    Abstract: The invention relates to a device which is used to film, record and reproduce video images in real time with a three dimensional appearance, using a video camera and a sonar system in order to obtain the depth information. According to the invention, an electronic system divides up the original image filmed in BGR format and each image is modified in accordance with the depth register (or programming) in order to form new images. Each image corresponds to a determined distance level. The result is displayed on a monitor comprising various independent transparent LCD (liquid crystal display) screens which are aligned one after the other. By displaying the images simultaneously, a single image is formed for the spectator, said image creating an appearance of volume and three-dimensional perception similar to low relief. The depth, video and sound signals are transmitted directly for reproduction purposes and to the magnetic tape recording system for storage purposes, using three magnetic tape heads.
