TI中文支持网1.首先图片如下，没有从第一行开始显示
2.我在vpfe_init配置中使用了中断，只有在设置VPFE_CCDC_VDINT = 0x01030000; //0x0103=258=576/2-5的时候才触发中断，设置代码如下：

Uint32 width;
Uint32 height;
width = 720;

3.image analyzer的设置为
4.摄像头标清，loopback程序中设置tvp5146模式为COMPONENT_IN,NTSC，请问我该怎么更改设置才能让图片显示正常呢？

1.我试了PAL，图片显示正常，但是没有同步信号了（不影响进入VDINT0中断）
2.请问你是怎么根据分辨率判断出来是PAL制式的？望解答，不胜感激！

回复 Chris Meng:
应该是用tvp5146_rget( 0x02 );读取就可知道了
user6003186：
老哥，我最近也在搞图像处理，用的DM6437,想请教一下关于中断的事？方便加个扣扣啥的吗
