| 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.

| Abstract: | 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 capured 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. |
