摘要： A display system includes a transparent display body having a first surface and a second surface opposite to the first surface, a sensor to detect a brightness of the transparent display body or a brightness around the transparent display body, an arithmetic unit configured to derive, based on the brightness detected by the sensor, a background luminance caused by outside light as when the transparent display body is viewed from a side of the second surface, and a controller to cause video to be displayed on the first surface, wherein where rear show-through luminance that is a luminance of the video that occurs on the side of the second surface is denoted as BB and the background luminance is denoted as SB, the controller controls a video luminance in accordance with the background luminance derived by the arithmetic unit such that (BB/SB) is less than or equal to a predetermined contrast value, the video luminance being a luminance at which the video is to be displayed on the first surface.

摘要： An image generator is provided which generates a monitor display image that facilitates easy recognition of a three-dimensional object in an overhead view image. An image generator includes: an overhead view image generation section for generating an overhead view image by performing a projective transformation, with a virtual viewpoint above a vehicle, of an image captured by an on-board camera for capturing an image of a surrounding region of the vehicle; a three-dimensional object detection section for recognizing a three-dimensional object present in the surrounding region and outputting three-dimensional object attribute information showing an attribute of the three-dimensional object; and an image composition section for generating a monitor display image for vehicle driving assistance by performing image composition of a grounding plane mark showing a grounding location of the three-dimensional object with a portion at the grounding location in the overhead view image, based on the three-dimensional object attribute information.

摘要： An overhead projector (100) including a Fresnel lens, a single element meniscus projection lens (132) having a concave side and a convex side, and a folding mirror placed in an optical path between the Fresnel lens (112) and the projection lens (132). The projection lens is oriented to have the concave side optically facing the Fresnel lens (112). The optical design of the overhead projector follows the following equation, FFres = (FLens(MLens+1)/MLens - SLD)/(MFres+1), where the Fresnel lens has a focal length FFres, and a magnification MFres, the projection lens has a focal length FLens and a magnification MLens, and SLD is the distance from the stop position and the projection lens.

摘要： A projector includes a housing having a single light projection source. A first condenser projects a first light beam from the light source, through an LCD image display screen mounted in the housing, and to a projection surface. A second condenser projects a second beam of light from the light source, to an overhead projector mounted on the housing, and to the projection surface. A beam blocking device is connected to the housing for movement into a position for selectively blocking the second beam of light.

摘要： The projector (11) of the present invention provides a means for interactively displaying and annotating a document image at two separate locations. The projector consists of an image plate (39) having an array of picture elements for displaying the image; a projection mechanism for projecting the image displayed by the image plate onto a projection screen (49); and a digitizer (41) having a coordinate input array which corresponds to the array of picture elements of the image plate (39), wherein the image displayed by the image plate (39) changes in response to coordinate inputs to the digitizer (41). A method for interactively annotating an image communicated between a remote and local image includes the procedure of simultaneously transmitting to the remote projector (107) annotations made to an image in the local projector (101). Image enhancement means are provided including an overlap-region calibration, a set of cross-polarizers (144, 146), a high-intensity strobed flash lamp (17) using interlaced scanning, sub-divided picture elements, and automatic gain correction.
