Other AbstractThe invention relates to a real-time video image alpha mixing system and a control method thereof. The method comprises the following steps that: a central processor receives image material data from a host computer, and the image material data is updated into a nonvolatile memory through a three-state bus bridge the image material data in the nonvolatile memory is written into a synchronous static memory a start direct storage access module writes local image data in the synchronous static memory into a local image cache an analog-to-digital conversion module converts an analog video signal into digital image data an input image cache is used for caching the input image data subjected to analog-to-digital conversion through the analog-to-digital conversion module an alpha mixed logic module performs image synthesis on the input image data from the input image cache and the local image data to be mixed from the local image cache and a digital-to-analog conversion module converts the synthesized image into an analog video to be output. The system and the method are low in cost, high in speed and high in practicability, and satisfy the information display application of fly-carried, vehicle-mounted and handheld video systems.
