摘要
通过分析S3C2440中摄像头接口CAMIF和摄像头芯片OV2640的工作原理,本文提出了基于嵌入式Linux的摄像头接口设备驱动程序框架,并据此框架在嵌入式Linux上设计并实现了摄像头的系统功能。实际使用结果表明,设计的驱动程序能充分满足实际应用需求。
In this paper, the principle of the camera interface （CAMIF） built on the S3C2440 and OV2640 chips are detailedly analyzed. Furthermore, we propose the implementation framework of the camera interface based on embedded Linux. In addition, we implement the device driver of CAMIF according to the aforementioned framework. Finally, the practical experiences show that our device driver can fully satisfy the real requirements.
