高手请进，OV9653问题，图像大绿大紫啊

iphoenix · 发表于 2009-8-13 09:20:16

[em01]各位高手，这是使用OV9653拍出的图像，严重不正常，是不是寄存器设置不正确?

我设置的寄存器值：

应该是数据格式的顺序有问题。例如YUV或RGB的顺序，需要重新调整。

输出格式问题吧，感觉应该是Y信号但被输出了G。入门级人物，也只有这点看法咯。。。[br]+1 RD币

恩，感谢楼上两位，得到的图片就是白的会变成紫的，黑的会变成绿的[em11]

我将摄像头的采样格式由CbYCrY改为YCbYCr后,颜色终于正过来了,再次感谢楼上两位,哈哈

lZ,你用的是什么平台。图像一上来就这么清晰吗。有用过yuv--->rgb的格式调整吗。你的参数是什么。

iphoenix · 发表于 2009-8-14 08:28:30

回楼上，我使用的是ARM9+Linux，图片最后是保存成JPG格式的，这个要用到libjpeg.so动态库

这个平台是做智能机还是NBC模组啊？

iphoenix · 发表于 2009-8-17 14:53:25

回楼上NBC是指美国国家广播公司不?我的理解NBC==NX Corporation.
我这个是要做个嵌入式的手持设备[em02]

nbc 是notebook camera吧？不要随意缩写吧。。。

iphoenix · 发表于 2009-8-18 11:55:48

哈哈，长知识了啊
