【摘要】：目前高端手机摄像头均为MIPI接口,该接口信号不能直接通过FPGA或DSP采集。但随着仪器设备的小型化趋势和手机摄像头性能的不断提高,使得在某些军事、工业设备上使用手机摄像头成为重要的方案之一。为了让手机摄像头在上述领域使用,本文设计了一种可以接收并处理MIPI信号的通用MIPI-PHY。选择适合的FPGA,设计电气匹配和管脚约束来采集专用电平的信号;再根据信号协议,将混叠了各种信息的MIPI信号进行处理,分离出行、场同步信号,进行时序整合;根据整合后的信息将图像信号解码成通用的LVCMOS信号并进行成像实验。在帧频为22fps、像素分辨率3 264×2 448时成像质量高、无畸变、长时间连续成像无丢帧现象,证明了该设计的可靠性和稳定性。同时程序可移植性强、输出为并行信号,满足开发人员的使用要求,已应用到某些具体项目中。
[Abstract]:At present, the high-end mobile phone cameras are MIPI interface, the interface signal can not be directly collected through FPGA or DSP. However, with the miniaturization of the instrument and the continuous improvement of the performance of the mobile phone camera, the use of the mobile phone camera in some military and industrial equipment has become one of the important solutions. In order to use the mobile phone camera in the above fields, this paper designs a universal MIPI-PHY. which can receive and process MIPI signals. Select the suitable FPGA, design the electric match and pin constraints to collect the signal of the special level, then according to the signal protocol, process the mixed MIPI signal, separate the trip signal, field synchronization signal, and carry on the time sequence integration; According to the integrated information, the image signal is decoded into a general LVCMOS signal and the imaging experiment is carried out. When the frame rate is 22fpsand the pixel resolution is 3 264 脳 2 448, the image quality is high, the distortion is free, and the frame loss phenomenon is not lost for a long time. The reliability and stability of the design are proved. At the same time, the program has strong portability, output as a parallel signal, to meet the requirements of developers, has been applied to some specific projects.
