Unity - Mobile - How to access to camera fields?

November 19, 2018 - 11:34am #1

Using Vuforia 7.5.26, Unity 2018.2.5f1 and building on Samsung Galaxy S8+, Android v8.0.0.



I need to adjust the "exposure-compensation" field.

This "for" loop doesn't output anything.

foreach (var f in CameraDevice.Instance.GetCameraFields())

{

    Debug.Log("key; " + f.Key);

}

I also tried 



CameraDevice.Instance.SetField("exposure-compensation", -2);

CameraDevice.Instance.SetField("exposure-compensation", "-2");

It also tested with a Nexus 5. This time, it can iterate through all fields but setting the exposure field doesn't change a single thing.

 

My main issue here is that using Vuforia, I must look at a LED. If I take a picture using my phone, the LED color is perfectly fine. When Vuforia is running and I access to the camera image, the LED looks oversaturated, almost white. I want to lower the exposure-compensation field. I'm also wondering why the image is so bad when using Vuforia. (My camera device mode is set to QUALITY in the vuforia configuration).



Please help me! Thanks

Hello,

Have you reviewed the following article about our Advanced Camera API? https://library.vuforia.com/articles/Solution/Advanced-Camera-API

The feature should also work with a Development license, but would need to be commercialized with a Pro license. I suggest you create a fresh Development key to insure the proper feature permissions are in place.

Thanks,

Vuforia Engine Support
