你好，我们的摄像头模组，并没有使用nvidia的isp，而是使用的摄像头自带的isp。所以你调英伟达的参数，当然不能生效。

我们的isp是通过一个脚本直接控制寄存器进行调节的。
强光下，你可以试试DOL宽动态：

Hi,
For VEYE-MIPI-327E, which is 2 boards,5V is necessary.
For VEYE-MIPI-IMX327S, which is 1 board, 5V is not necessary.

@tuzi said in veye imx327:

nvoverlaysink

可以给nvoverlaysink加个参数，控制一下显示区域。或者换一个其他sink试一下。

我暂时不能直接提供答案，你可以参考英伟达这个部分的文档略作研究。

Ok, will connect wire from IRLED to gpio.

@watchever IMX385

Thank you.

@viktor
You are welcome. Have a good day.

@seka OK~

@watchever
Do you use VEYE-MIPI-IMX462 ? I think it do not support other resolutions other than 1080p.

This is a limitation of ISP.

Ok got it. I confirm output format is I420 and array order is correct. Thanks for your help

@hezudao
不客气~

@veye_xumm 由于时间太久了,客户没有进一步的反馈,我会把这个帖子标记为已解决.

@watchever
Hi, it is the ISP limit which VEYE-MIPI-IMX462 used.

@seka
I'm not very familiar with python. But in my opinion, jpeg is compressed data, which can't be subset by simple sampling, is it?

@xsw
很好。
硬件是被动的，软件是主动的。
摄像头不能去操作主板的内存，是靠主板上的软件来操作摄像头，把数据放到内存。
树莓派是上我们提供的两种应用模式，都可以由软件获取到摄像头输出的数据。
请参考详细的文档和代码。

@veye_xumm 哦，好的，那可能是采购给我的型号弄错了，我用327的dtb再试一下，谢谢了

@dan_lionking
You are welcome.

@watchever
I think what you mentioned is mshutter. Yes, of course.
mshutter :
If you use manual mode, the exposure time will be independent of the ambient brightness.

@watchever
For yuv ，

And I'm sorry , can not provide you such python code now.
