Hand Held Terminal for Battlefield Broadcast

Not Available Display systems for training devices and other applications that have the need for channel to channel seam matching impose stringent image mapping requirements. In high performance visual systems, image matching functions are typically performed in the image generator (IG) or the projection system. In CRT projection systems, image mapping is implemented using analog raster shaping. In digital display based projectors and monitors, pixel location is invariant, which, although providing the blessing of lifetime stability, precludes adjustment for seam matching. For such applications, high performance IGs can perform the image mapping functions. In application where low cost IGs or 3-D accelerator cards drive digital display based projectors and monitors, the image mapping function can be performed in an intermediate image-mapping system. Since such a system operates by processing video content, it is a logical place to include other desired video processing, such as multiple image suppression, and intensity modification to correct system nonuniformities and blend edges. Under this Phase I SBIR, DVC applies its extensive digital display and image mapping experience to define and recommend cost effective digital system solutions for mapping and other desired processing. They includes algorithms, software/firmware functions, electronic modules, with performance specifications for such an image-processing system.
