I used the MIPI CSI-2 RX subsystem example design and did not make any change. I used the IMX-274 sensor and the vivado version is 2019.1. The video output from HDMI are as follow. These photos were taken on a mobile phone and the picture quality is a bit low. Generally speaking, there are some colorful and strange colors in some places in the picture and the picturea are very unclear.
And I modified the project to fit my camera sensor. This sensor is a mono camera sensor and the video output from HDMI are as follow. The result is similar to the video produced by imx274.

Thank you for your reply @watari
I can get the following message from the program:
And I don't know how to change the color mode on the HDMI monitor. I used another monitor and got similar result.
I saw the output of the example design on other posts. The picture he sent was clear and no strange color but just greenish.

I red your reference post and your message on it.
According to this post, image sensor doesn't have any pre-image procedures.
So, at least you need to implement some image procedures. (ex. white balance, bayer filter and so on)
In your case, it seems that you confirm white balance setting, bayer filter and color space which I already mentioned.
Would you try it ?

Are you using one of Xilinx demos? Did you change the camera settings, changing camera settings can get a good quality.

Thank you for your reply.
Yes, I used the mipi csi-2 rx subsystem example design introduced in PG232.
Now it seems to be a problem with the vivado project because the same problem occurs when I change the camera. I suspect that the decoding error of mipi signal caused some problems in the color space. But I don't know how to modify it.
I didn’t make any changes to the example design when using the IMX274 sensor. I don’t know why I get different results than others

Thank you for your reply @karnanl
My board's version is 1.1. The recommend version in PG232 is 1.0. Will the difference of the borads'version affect the mipi decoding? How should I modify my project?
Any idea will be appreciated.

To be honest I've never use ZCU102 rev1.1.
1. Do you have access to ZCU102 rev1.0 ?
2. Do you have access to DSI Panel (AUOS display panel (B101UAN01.7_H/W 1A)?
# I am suspecting that your HDMI monitor may cause this issue....

Are you still running into an issue?
To summarize the thread:
As I understand, the image below is from an example and not your system. Is this correct?
Can you try rebuilding the Vivado project and elf? I don't expect this to be an issue, but it is an easy double-check.
Next, can you test your HDMI cable? And possibly the HDMI output port of your ZCU102? There are many designs that use the HDMI port, you can use the HDMI example design in chapter 5 of the HDMI PG, or most of our TRDs also use the HDMI connection.
Thanks and regards,
