# XR camera subsystem
|
||
|
|
|
||
|
|
The camera subsystem manages a hardware camera on the AR device. It provides the following data:
|
||
|
|
|
||
|
|
- Camera image (as an "external" texture on the GPU).
|
||
|
|
- Camera image (as a buffer of bytes available on the CPU).
|
||
|
|
- Projection matrix, used to set the field of view and other properties of the virtual camera according to the physical one.
|
||
|
|
- Display matrix, used to orient the camera image correctly.
|
||
|
|
- Camera intrinsics that describe a mathematical model of the camera, useful for computer vision algorithms.
|
||
|
|
- Camera conversion utilities for converting the CPU image to RGB and grayscale.
|
||
|
|
- Light estimation information (color and brightness of the environment).
|
||
|
|
- Camera focus mode (autofocus or fixed).
|
