摘要
为了实现嵌入式Linux对CMOS图像传感器OV2715的支持,对OV2715的工作原理进行深入的研究,针对OV2715功能复杂和驱动编写困难的问题,提出一种模块化设计OV2715驱动的方法。在DM3730硬件平台下,将OV2715驱动分为I2C设备驱动和V4L2接口驱动并分别进行了实现,最后,设计视频采集程序并对驱动进行了测试。测试结果表明,输出视频图像质量清晰稳定,该实现在高清数字监控系统中有较好的应用前景。
In order to support CMOS image sensor OV2715 by the embedded Linux, the working principle of OV2715 is deeply studied, and aiming at the problem of complex function of OV2715, a modular design method for OV2715 driver is pro- posed. On the DM3730 hardware platform, the OV2715 driver is divided into I2C device driver and V4L2 interface driver for re- spective implementation. The video capture program was designed. The driver was tested. The test results show that the output video image is clear and stable. It has a good application prospect in high-definition digital monitoring system.
