CDC in the context of Android refers to

Camera Driver Core

. It[SQ]s a component of the Android camera system that handles the low-level communication between the Android framework and the camera hardware. It[SQ]s responsible for things like :

*

Hardware abstraction:

Providing a consistent interface to the Android framework regardless of the specific camera hardware used. Different camera chips from different manufacturers will have different low-level control mechanisms; the CDC hides these details.

*

Image acquisition:

Controlling the sensor, image processing units (ISPs), and other components to capture images and videos.

*

Sensor configuration:

Setting parameters like exposure, ISO, white balance, and focus.

*

Data transfer:

Moving captured image data from the camera hardware to the Android framework.


In essence, the CDC is a crucial part of the camera stack that makes it possible for Android apps to easily access and utilize the camera hardware without needing to worry about the complexities of the hardware itself. It[SQ]s part of the overall camera pipeline, which also includes the Camera HAL (Hardware Abstraction Layer) and higher-level frameworks within Android.
