摘要： A method and apparatus for establishing consistent image brightness, especially for a multiple video image seamless display, is provided by storing a set of smoothing factors, one for each detail element of each image, in a memory. Upon projection, the smoothing factors are applied to the brightness components of the associated detail elements of each image. The smoothing factors are selected by applying a standard curve, coarse tuning major curve parameters in response to the appearance of the projected multiple image display, and fine tuning smoothing factors for specific detail elements, the locations of the detail elements being indicated by a cursor on the display.

摘要： An integrated display system includes multiple displays and a transmissive/reflective mirror with a mirror face. Images from display areas of one or more displays are passed through the mirror face and provided to a viewer. Images from display areas of one or more displays are reflected by the mirror face and provided to the viewer. The displays are arrayed to generate a seamless composite image from the images provided by the displays.

摘要： A three dimensional smoothing factors lookup table provides detailed control over the full two dimensional space of a composite image composed of multiple projected raster images. The overall displayed image is improved by adjusting the brightness, gamma, and contrast of individual detail elements of the image according to predetermined smoothing factors. A set of smoothing factors is generated by measuring the reflective brightness of detail elements of the projected image to produce a reflective brightness contour map and mathematically inverting the contour map to produce an inverse map. The inverse map is used as smoothing factors to match the colors output by various projectors in an arrayed projection system. The three dimensional smoothing factors lookup table also enables performance of additional image improvement functions, including projector shading, color shift correction, correction of optical vignetting, and automatic edge definition.

摘要： An apparatus and method for analyzing the brightness characteristics of a projected image and using the analyzed characteristics to improve the appearance of the projected image is disclosed. In one embodiment of the invention, the brightness characteristics of the projected image are analyzed at selected points across the raster of the image. An analysis array or array of data elements including brightness components corresponding to detail elements is then generated. The data elements in the array are then used to create compensation signals that are applied to the projected image through, for example, an overlay of smoothing factors or generation of a smoothing curve, to enhance the quality or appearance of the image by improving the regularity of brightness in all areas of the image. This regularity of brightness across the full span of the image is useful as a general improvement to the image and as a compensation for projector or projection surface brightness anomalies. In arrayed projection applications, central hot spotting, edge vignetting, electron beam or light source misalignments all can detract from evenly displayed images and all can benefit from the application of compensation that depends on an analysis array of the projected image.

摘要： There is therefore provided according to a presently preferred embodiment of the present invention, a compact and ergonomic computer workstation with a high resolution, wide angle projected display. In an exemplary embodiment, the workstation appears generally to resemble a desk with a deep surface that separates a desk section and a display section including a large projection screen. The desk section includes a desk module with a work area that is preferably shallow and wide with enough surface to accommodate computer input devices and work tools. The work area ends at a barrier between the desk and display sections and is isolated from the display mechanically. The display section includes a preferably self contained projection module consisting of a frame and sub modules of projectors, stands, integral milTors and coordinating mounting hardware that position a group of projectors below the eye line and direct the light output to a front viewing screen. The frame creates a housing for the image source and the projection apparatus that is isolated from the desk section mechanically so that forceful action taken to the desk will not be transmitted to the display section. In operation, the images are overlapped and blended to create a computer viewing and control workstation with a large, high resolution panoramic display that may be comfortably viewed by an individual or several people at the same time. With typically 2.5 or more times the resolution or pixel count of a single monitor display, this form of computer display allows the operator to assemble more visual elements on screen, open more windows, have more programs ruling and see more in a single image.
