摘　　要：研究了视频瞄准系统中"+"字分划线叠加问题,该模块由CCD视频图像采集器、单片机、视频字符叠加芯片、按键、显示器及相关电路组成。应用视频叠加技术,以MAX7456为核心产生电子分划线。实验结果表明,该瞄准镜可准确地叠加电子分划线,显示清晰的瞄准目标图像,具有瞄准实时性强、操作简便、灵活可靠等特点。This paper has studied electronic sub-dash in a video aiming. It consists of CCD image sensor,microcontroller unit, the chip of video aiming generating electronic sub-dash, press keys and some electric circuit. Using the technology of screen dis play, the electronic sub-dash is produced with MAX7456 chip. The experimental results indicate that this video aiming could gen erate electronic sub-dash accurately and display the target image clearly. It also has the advantages of aiming in real-time, opera tion flexibility and reliability.
