摘要： This invention provides a stereoscopic display without using eyeglasses which does not require a means to switch images for left and right eyes and by which each viewer can observe a stereoscopic image even when many persons observe an image. The display includes a projector for a left eye 1L, a projector for a right eye 1R, and lenticular lens on a light incident side 2a which forms images for left and right eyes projected from each projector on a diffusing plate 2b alternately. A shutter means 4L, 4R include a plurality of shutter regions which can switch between light transmission and light shading and are placed laterally, and form a narrow-width image light reaching region, of which width is less than that of the shutter region, in each image forming region on the diffusing plate. Lenticular lens on a light incident side 2c guides an image in a narrow-width image light reaching region in an image forming region for a left eye to a viewer's left eye and an image in a narrow-width image light reaching region in an image forming region for a right eye to a viewer's right eye. A shutter control means 5 controls light transmission and light shading of said shutter region on the basis of output results from a sensor which detects a viewer's position.

摘要： There is provided a stereoscopic video display that enables a viewer to recognize a more real stereoscopic video.A light source device 2 comprises a backlight 21 and a pinhole array plate 22. A liquid crystal display panel driver 5 feeds a pixel driving signal to a liquid crystal display panel 3, to form a pixel region 3a composed of a plurality of pixels respectively corresponding to pinholes 22a. Each of the pixels composing the pixel region 3a controls an amount of light transmission with respect to a light beam in each direction from the corresponding pinhole 22a. Consequently, the intensity of the light beam in each direction is reproduced. Lines respectively connecting the centers of the pinholes 22a and the centers of the pixel regions 3a are not parallel to one another, and are so set as to cross at one point of a position corresponding to the standard distance between the video display panel 3 and a viewer Z. Therefore, the light beams are efficiently concentrated at a standard viewing position, thereby making it possible to make the viewer Z recognize a more real stereoscopic video.

摘要： An image signal storing unit stores an image signal provided from the outside. An image processing unit appropriately processes the image signal stored in the image signal storing unit in accordance with the instruction from an adjusting unit. A projecting unit projects, onto a display area, light corresponding to an image created by the image processing unit. A display size determination unit computes the display size of the picture plane displayed on a screen based on an image captured by the camera provided adjacent to the projection-type video-image display device. The display size determination unit then determines whether or not the display size of the picture plane is equal to or larger than a predetermined upper-limit size.

摘要： An image signal processor includes a controller configured to generate a red output signal, a green output signal, a blue output signal and a fourth color output signal in accordance with image input signals. A fourth color light component enables to reproduce a color outside the range of a color reproducible by the red light component, the green light component and the blue light component. The controller generates the fourth color output signal on the basis of a reference signal corresponding to a color different from a complementary color of a color reproduced by the fourth color light component.
