    摘要： A near-eye light field projector (1) comprising point light sources (111, 112,113) arranged in a light source plane (10) and emitting an incident light beams (200); a modulation device (40) generating diffracted modulated light beams (410, 411, 412); projection optics (21, 22) forming images (310, 511-513) in an image plane (60); and relay optics (23, 24) forming viewpoints (810) in a viewpoint plane (80). The point light sources (111, 112, 113) are arranged such that diffracted modulated light beams (410) are combined and form combined images (310) while other diffracted modulated light beams (411, 412) form diffracted images (511-513). The light field projector (1) further comprises a spatial filter (61) configured to block the diffracted modulated light beams (411, 412), such that the relay optics (23, 24) projects only viewpoints (810) from the combined images (310).

    摘要： Light other than visible light is emitted from a video image display section such as a screen, together with display images, so as to degrade image quality of illegally camcorded video images, thereby making it impossible to use the illegally camcorded image contents. A video image display system (1) includes a projector (202) that generates a display image; and a screen (203) on which the image generated by the projector (202) is projected and displayed. On a backside of the screen (203), there is provided an infrared ray emitting unit (204) that emits infrared light from a video image display surface during a period while video images are being displayed on the screen (203). The infrared ray emitting unit (204) includes a wavelength cut filter that substantially does not transmit a predetermined wavelength component close to a visible light region, among the light emitted from the infrared light source.

    摘要： A photographic and projection device is disclosed. The photographic and projection device includes an image sensor device, a lens assembly, a movable reflective mirror, and a display panel. The movable mirror has a reflective surface, and the movable mirror is disposed between the lens assembly and the image sensor device. The display panel is located towards the reflective surface of the movable reflective mirror. When the movable mirror is located in a first position, an external image can be formed on the image sensor device by the lens assembly, and when the movable mirror is located in the second position, the image of the display panel can be projected to the outside by the movable mirror and the lens assembly.

    摘要： A colour optical system ( Fig. 41 ) comprises three colour channels for handling light of three different colours, output from the three channels being combined to create a colour image. Each channel includes a light source (11), first diaphragm means (12), and an optical element (14) having at least one cell (1) comprising two deformable dielectric layers (4, 5) which meet at an interface, at least one of which (5) is a relief forming gel, a first electrode (6) on one side of the layers and signal electrode (3) on the other side of the layers, and means for supplying a signal to the signal electrode to create a relief to modulate light from the light source. There is a common second diaphragm means (16) to receive combined output from the three channels, the second diaphragm means being in the form of a system of light filters capable of stopping light fluxes of zero orders of diffraction but passing light fluxes of higher orders of diffraction for all three colours.

    摘要： A multimedia player for providing two projection images is provided. The multimedia player for displaying two projection images includes: a first projection unit displaying a first projection image; and a second projection unit displaying a second projection image. The first projection unit includes: a first driving unit controlling an operation of the first projection unit and providing an image signal on the first projection image to be displayed; a first light source unit; a first light modulation device outputting the first projection image by modulating light provided from the light source in response to the image signal of the first projection image; and a first projection lens unit magnifying and projecting an image that is output from the first light modulation device. The structure of the first projection unit is the same as that of the second projection unit. The multimedia player further includes a screen sensing unit sensing a color of an area in which an image is to be displayed. The first and second driving units detect a complementary color of a color sensed by the screen sensing unit and increase brightness of a light source corresponding to the complementary color among light sources of the first and second light source units or image data corresponding to the complementary color among image data to be displayed, thereby improving visibility.

    摘要： A light modulator has two deformable dielectric layers (4, 5) which meet at an interface, at least one of which (5) is a relief forming gel, a first electrode (6) on one side of the layers and a signal electrode (3) on the other side of the layers to which voltage pulses are to be applied in accordance with desired signals. The signals are such that a relief is created with a profile such that the modulator will act as a lens (Fig. 18). The electrodes may be arranged a concentric circles (42), whose radial extent may reduce from the centre outwards. The radius of curvature of the profile may be varied to alter the focal length. The gel may be a polyorganosiloxane gel. There are also disclosed methods of making the gel, modulators, and optical systems using the modulators for both monochrome and three colour work.
