摘　　要：设计了一个全数字硬件架构的投影图像边缘融合处理器。该处理器有别于目前业界已有基于计算机体系构架的传统控制器,以FPGA为中心、配以相关IC芯片,精选融和函数的设计,再结合硬件描述语言将图像的边缘作淡入淡出处理。在处理中将每幅投影单元图像融合区的亮度变化抽象成相应的融合曲线,通过引入适当的融合函数和根据显示终端的电光特性予以伽马校正,并提出根据实际投影效果实时调整的融合方案。文章最后给出了实现高质量无缝拼接的实例结果。The paper presented the design of a new seamless tiling of projection display controller, which is different from the common processor based on the computer system. This controller is constructed with the FPGA device and some coding and decoding IC and the software is designed by the VERILOG hardware description language to realize the fade-in and fade-out Principle. In this design, the change of the brightness is according to the function. It can be realized that the high-quality seamless tiling through the proper amalgamation function which can be adjusted by the gamma correction and the real display effect.
