Design and optimization of Camera HAL layer based on Android

EasyChair Preprint no. 1480

Abstract

In this article，our design is based on the Android platform to optimize and improve Camera HAL. This design is applied to the development of the Android system, the design of the Camera subsystem, the description of the Camera subsystem from the structure, function and data flow, and then proceed to structural optimization. After completing the optimization and improvement of the structure, we implemented our own Camera HAL architecture on the TI AM335x platform. This design uses TI AM335x as the hardware platform, based on Android system, designed and implemented the Android Camera hardware abstraction layer and Camera subsystem. At the end of the development, after the actual experimental test, the development of the system achieved the expected function and worked well.

Keyphrases: Android, Camera, embedded system, HAL, system architecture
