Linux 摄像头驱动的设计优化及其对应的 Android 下HAL 封装设计方法探究
DESIGN AND OPTIMISATION OF LINUX CAMERA DRIVER AND PROBING CORRESPONDING METHOD OF HAL ENCAPSULATION AND DESIGN UNDER ANDROID
摘要
Abstract
For current status of camera driver in Android system not being the open-source,by learning form the related driver in Linux, we proposed an integrated design scheme to improve the design of driver and optimise it as well,especially in FIMC driver,we composed the FIMC and ov9650 into a single device,this significantly improved the operation efficiency of camera driver.After that,by analysing Android framework,we designed a HAL module,which completes the functions of camera with three threads in parallel,we also used it to encapsulate Linux camera driver.The content of the paper includes the design and optimisation of Linux camera driver,the design of Android HAL module,and the specific procedure of encapsulating the Linux camera driver with HAL. In end of the paper we submit the experimental result.关键词
