ov56xx摄像头：拍照后只能看到照片里很亮的东西。其他的都是黑色的

ryangio 2011-11-22 05:55:28
在android调试ov5640的摄像头。在拍照的时候只能拍到照片里很亮的东西。比如灯光，在照片里其他的什么都看不到，
不知道这个现象跟什么有关系？
请高手赐教。

一般用databook 中的default 值就可以，寄存器设置多试验。

你好，我目前也在调试ov5640，平台是i.mx51，现在preview以及拍照都没有问题，目前卡在自动对焦那里，配置之后不起作用，我有各个分辨率下的寄存器配置，留下邮箱发给你！你调试自动对焦了吗？

你的PLL输入是多少MHZ的。

我现在调试这个ov5640也遇到问题；预览的时候出现很多小绿点 又水波纹。ov的FAE支持也不到到位。
大家能否发一个驱动给我呢.hangbing0203@163.com

如果发现某个分辨率下拍不了照片时，把0x3035这个寄存器的高四位加大一点试试

你好，我目前也在调试ov5640，平台是i.mx51，现在preview以及拍照都没有问题，目前卡在自动对焦那里，配置之后不起作用，我有各个分辨率下的寄存器配置，留下邮箱发给你！你调试自动对焦了吗？

帮忙看下
这可能是全网最详细的关于OV7670的文章
最离谱的是有一个非官方的文档（但是写的其实还行），里面有简单介绍了一下 OV7670摄像头模块，看得出来这文档是真正的技术人员写出来的（比如像我这种，写东西就非常的口语化，一看就知道是真敲过代码才写东西的 ），然后我在那个XX电子的文档里看见了几乎一样的（没错，就是我买的YY科技店铺然后给的XX电子的链接里的资料），为什么我说几乎一样呢？还有一些寄存器在初始化的时候反反复复配置了好几次，我直接？最后生效的是最后一次配置的，那你之前配置干嘛？我寻思OV7670关于配置寄存器也没有时序的要求啊？
