摘要
基于BF561平台实现了视频采集的单帧送显以及连续帧的实时送显。由于LCD的数据显示格式和摄像机采集数据格式不同,提出了一种基于查表法的数据格式转换的快速算法,并在DSP平台上对此进行了优化,大幅度降低了用于显示的DSP指令周期数。
Based on BF561 platform, the sending and display methods of single-frame or multi-frames image data are introduced. Because the date pattern displayed on LCD and eapured by video camera are different, for the purpose of fast format-conversion between the datas of collection and delivery, an algorithm is proposed bases on a look-up table method. In this way, the display consumption of DSP instruction cycles for one frame can significantly reduced.
