Abstract本发明涉及一种实时视频图像α混合系统及其控制方法,包括中央处理器,接收来自主机的图像素材数据,并经三态总线桥更新到非易失性存储器中;将非易失性存储器中的图像素材数据写入同步静态存储器;启动直接存储器访问模块将同步静态存储器中本地图像数据写入本地图像缓存;模数转换模块将模拟视频信号转换为数字图像数据;输入图像缓存用于缓存模数转换模块经模数转换后的输入图像数据;α混合逻辑模块将来自输入图像缓存的输入图像数据和来自本地图像缓存的待混合的本地图像数据进行图像合成;数模转换模块将合成后的图像转换为模拟视频输出。本发明成本低、速度快、实用性强,满足了机载、车载及手持录像系统的信息显示应用。
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.
