A stereoscopic image display device that is capable of reading out and setting a stereoscopic effect control value suitable for a monitor size of a display monitor used to display an image is disclosed. A stereoscopic image for stereoscopically displaying an image is generated based on a multi-viewpoint image, and the stereoscopic image is displayed on a display monitor capable of stereoscopic display. At this time, a stereoscopic effect of the stereoscopic image displayed on the display monitor is controlled. A controlled stereoscopic effect control value and a monitor size of the display monitor used to display the stereoscopic image when the stereoscopic effect is controlled is associated with the multi-viewpoint image and recorded in a recording medium.

Various embodiments of the present invention are directed to image viewing systems. In one aspect, an image viewing system includes a projection system (104, 504, 604), and a dynamically reconfigurable screen (102, 502, 602). The projection system projects two or more images of perspective views of objects or a scene onto the screen. The screen is dynamically reconfigured to separately reflect each image to an associated viewing zone, enabling a viewer looking at the screen to the view the objects or the scene from different viewing zones

A display apparatus for displaying multiple images of viewing angles is disclosed. The display apparatus comprises a display screen and a projector. The projector has at least one light source module, an optical component module, a first light modulator, a second light modulator and a projection lens. The light source module generates a light beam, which is divided into a first portion light and a second portion light after passing through the optical component module. The first portion light and the second portion light are respectively received by the first light modulator and the second light modulator, and transformed into the image of the first viewing angle image and the second viewing angle respectively. Then, the image of the first viewing angle and the second viewing angle are projected to the display screen by the projection lens simultaneously.

A display device includes a projector, a Fresnel lens converting a projected light from the projector into a nearly parallelized light, a screen with light reflectivity on which an image by the projected light from the projector is generated, and a retrotransmissive material forming another image of an image located on one side of an element plane in a position in a space on the other side of the element plane such that the image and the other image are symmetric with respect to the element plane. The retrotransmissive material forms an image by a light that has obliquely entered the element plane, such that a position from which the light has obliquely entered the element plane and a position in which the image is formed are symmetric with respect to the element plane, and thereby forms a real image of the image on the screen.

A laser projection system is disclosed. The system includes a laser projector that projects a light beam to the surface of an object and scans that projected light beam over at least a portion of the surface, wherein a portion of the projected beam is diffusely reflected from the surface back to the system. The system further includes an optical signal detector that receives the feedback light beam and converts it to an image signal, a light suppression means for suppressing unwanted light from entering the optical signal detector, and a computer for producing a measurement of the distance from the projector to the object surface, and controlling the system to buck the laser projector into a coordinate system of the object using three or more features on the object, wherein at least one of the three or more features serves as a targetless fiducial point.

An upper LCD capable of displaying an image which is stereoscopically visible with naked eyes is provided on an upper housing of a hand-held electronic device. A 3D adjustment switch for adjusting a parallax of a stereoscopic image is provided on the upper housing. When a slider of the 3D adjustment switch is within a predetermined range between an uppermost position and a position slightly above a lowermost position, the stereoscopic effect of the stereoscopic image is adjusted based on the position of the slider. When the slider of the 3D adjustment switch is at the lowermost position, a planar image corresponding to the stereoscopic image is displayed on the upper LCD.

A display apparatus includes: a cylindrical casing which is rotatably driven; and a plurality of curve-arranged displays which are installed inside the casing and have the same number as a plurality of slits formed in the casing, wherein the curve-arranged displays include a light housing which is an approximately semi-cylindrical column having a hollow structure, and a plurality of display device substrates installed on an arc-shaped side surface of the approximately semi-cylindrical column of the light housing.
摘要:
A method and apparatus are described for monitoring frame alignment status and correcting misalignment for film in a stereoscopic 3D projection system, in which gap indicia are provided onto the film in a gap between images, whether the images belong to the same frame or different adjacent frames. Thus, gap indicia are positioned in at least one of an interframe gap and an intraframe gap of the stereoscopic film. During projection of the film, presence or absence of the gap indicia is used to determine a frame alignment status. Frame misalignment is then easily diagnosed and corrected. Characteristics of the gap indicia are modified for improving frame alignment diagnosis.
