ENHANCED DIGITAL VIDEO ENGINE |
摘要 |
2064070 9108638 PCTABS00005 Programmable apparatus for digital processing of video signals from multiple sources converted to digital format to provide real-time multiple simultaneous special video effects and suitable for direct interface to a conventional microcomputer bus such as an Apple Macintosh R II NuBus. The apparatus includes a matrix of multipliers to do real-time video processing permitting special effects such as fading between at least two video image sources, as well as a priority resolver to control display on a pixel by pixel basis of more than ten sources based upon dynamically programmable priority. In addition, a programmable multiple range thresholder, a hardware window generator capable of generating multiple simultaneous windows, a color look up table and optional image capture capabilities are provided. The apparatus also provides for a light pen input, genlocking and a range of special video effects including zooming, mosaicing, panning and blending.
