摘要
针对目前移动嵌入式领域中广泛使用的MIPI CSI-2接口,设计了一种基于Lattice FPGA的实时图像采集与处理系统,实现了高清图像采集、Bayer格式转换、图像缩放、图像倒置和饱和度调整等多种功能。通过对系统进行功能验证与测试,表明系统可以稳定地采集1080p60的图像数据,并完成相关的图像处理功能,具有一定的实用价值。相对于其他平台,采用FPGA具有实时性高,功耗和成本低以及系统升级方便等优势。
A real-time image acquisition and processing system based on Lattice FPGA is designed for MIPI CSI-2 interface which is widely used in mobile embedded field.This system implements high-definition image acquisition,Bayer format conversion,image scaling,image inversion and saturation adjustment and other functions.It is shown that the system can stably capture 1080p60 image data and complete related image processing functions,through functional verification and testing of the system.It proves that this system has a certain practical value.Compared with other platforms,FPGA-based system has the advantages of high real-time performance,low power consumption,low cost,and easy system upgrade.
