Other AbstractThe utility model relates to a real-time video image alpha mixing system, which comprises a central processing unit, wherein image material data from a host machine is received and is updated to a nonvolatile memory through a tristate bus line bridge, image material data in the nonvolatile memory is written into a synchronous static memory, a direct memory visit module is started for writing local image data in the synchronous static memory into a local image buffer memory, an analog to digital conversion module converters analog video signals into digital image data, an input image buffer memory is used for the buffer storage of input image data after the analog to digital conversion by the analog to digital conversion module, an alpha mixed logic module carries out image synthesis on the input image data from the input image buffer memory and local image data to be mixed from the local image buffer memory, and a digital to analog conversion module converts the synthesized image into analog videos to be output. The real-time video image alpha mixing system has the advantages of low cost, high speed and strong practicability and meets the requirement of the information display application of airborne, vehicle-mounted and hand-held recording systems.
