Image quality...

[smallfly]

Hello,

The image returned by Unity's WebCamTexture appears to be of lower quality compared to the actual passthrough, even when capturing at 1920x960 resolution. Is this a known limitation of WebCamTexture, and could using the native Camera2 API provide better image quality?

Thanks

In the sample, it's using the WebCamTexture which demonstrate the common use cases with Camera in Unity.

But PCA should be compatible with Camera2 API, you can find more information about native camera access there
https://developers.meta.com/horizon/documentation/native/android/pca-native-documentation

and combine some project like https://github.com/yasirkula/UnityNativeCamera to check if you can get a better result.

Sorry for the late reply, and thanks for your response.
But, how is the image quality you’re getting with WebCamTexture?

For webcamtexture the max resolution is 1280x960

My issue isn’t the resolution per se, but it’s that the passthrough image I capture looks very jagged and rough compared to passthrough displayed directly in the headset. Here's an example image I captured for reference; see the lines of the drawing or the controller strap on the top right.

Is this visual quality expected when using Unity/WebCamTexture? Or is there something I'm missing in the setup?
(I have tried several things/'formats' when capturing and saving the image, but nothing helps)
Would the native API provide better quality?

Thanks,

Hi, it's a known issue, and we are going to improve the image quality with antialias in our frag shader.

Thanks for the reply. Will this be soon available ?

Is this issue also here when using the Native API ?

Thanks
