TDA4VM: Green/pink saturation in images in sunlight or lack thereof

Prithvi Kambhampati

Part Number: TDA4VM

Hi,

We are currently using the TDA4VM board with the Sony IMX390 sensor to collect some images. We observe that there is a green saturation during bright sunlight and pink saturation during a cloudy day. I have attached the corresponding videos below. We are saving the output of the scaler node (capture -> viss -> scaler -> write_image). Is there any setting that solves this problem?

There is a significant drop in our object detection model performance due to this.

Let me know if you need further information from me.

Regards,

Hi Mayank,

We are using an engineering release of SDK 7.0 from D3 to collect the data. We are using the production release of SDK 7.0 with patches for tidl_j7_01_03_00_05 to run our object detection model.

Regards,

Prithvi

Hello Prithvi,

These issues were fixed in 7.1 release. D3 was also given IMX390 driver patches to be applied on 7.0. Can you please confirm that those patches have been applied in your build?

Regards,

Mayank
