Exposing the Android Camera Stack

Android 4.0 was released with support for many advanced Camera Features like Video Snapshot, Face Detection, and Video Stabilization. This presentation provides a technical deep dive into the Android Camera Stack Internals. The Camera.Parameters pipe-line enables different image sensors to expose its hardware specific functionalities to the application layer. The system level camera service interacts with the media framework, the display subsystem, and the camera hardware via an implementation of the Camera Hardware Abstraction Layer (HAL). The Low Level Camera Interface discussion will include a general overview of camera hardware, the hardware interfaces used by the camera (control and data), and the driver interface to the camera. The intended audience for this conference session is engineers who want to learn more about the Android Camera Internals and driver Architecture. Cameras in mobile devices have gone mainstream and this talk should facilitate engineers wanting to integrate, improve or innovate using the Camera subsystem.
