摘要
介绍一种高度集成并具有广泛通用性的视频图象信号采集系统。系统的开发采用了功能强大的视频解码芯片SAA7114H和可编程逻辑门阵列器件(FPGA),并考虑了在线编程的模式。文中给出了YUV色彩空间与RGB色彩空间的转换公式,经验证效果很好。在实际应用中,该系统作为前端图象采集部分取得了良好的效果。
In this paper ,a high-integrated, general-purpose image signa l acquisition system has been introduced. This system is designed by using o ne special integrated video decoder, a field programmable gate array a nd in-system program module . Conversion formulas between RGB and YUV color s pace with well validated effect are given .In practical application , the syste m is used for foreside image acquisition model with a good effect.
