多功能数字摄像系统的设计

Design of Multifunctional Digital Vidicon System

基于FPGA的数字摄像系统由光学子系统、系统控制层、图像高速采集处理模块、音频采集处理模块、电源模块和与外设接口等部分组成。系统采用单MCU方案,以单片机作为中央控制器,用FPGA实现了实时图像处理和静止图像的数字特效处理,以及视频和静止图片压缩。

The digital vidicon system consists of optical subsystem, system control layer, high speed collection ＆ manipulation module for image, audio collection ＆ manipulation module, power supply module, the peripheral interface and so on. The single MCU scheme is adopted by system and SCM is used as MCU in the system. Real-time image manipulating, digital effect of static pictures, video compressing and static image compressing are implemented with FPGA in the system.
