基于S3C6410和ADV7180的嵌入式视频采集系统设计与实现
Design and Implementation of Embedded Video Capture System Based on ADV7180 and S3C6410
摘要
Abstract
High-end video capture applications need not only a flexible and convenient interface but also a powerful data processing capacity. Both should be integrated properly to create conditions for a wide range of video acquisition and processing. Embedded image capture should be real-time and reliable. According to these characteristics, using the decoder chip ADV7180 and the high-sensitive and antijamming CCD camera, a new image capture and storage system is designed where the S3C6410 is used as the main chip. We develop the ADV7180 drivers under the Linux platform, and mainly describe how to configure the ADV7180 registers through the I2C bus correctly and how to write video data into the SDRAM through the DMA channel. The paper details the method how to extract YCbCr4:2:2 format data. Converted video data is written into frame buffer of LCD for show. Test results show that video capture interface is effective and easy to use, and the collected images are clear, smooth and high realtime.关键词
