摘　　要：数字图像处理技术的高速发展需要更加强大的高性能图形处理器提供支持.为了满足图形处理器在RGB颜色空间进行视频图像处理时,可以单独改变某个颜色属性(色度、饱和度或亮度)来调整视频图像显示效果而不影响其它属性的需求,本文研究一种流水处理的HSV调整电路的设计与实现.采用RGB到HSV颜色空间转换、HSV调整和HSV到RGB颜色空间转换关键模块设计电路,重点实现了核心模块HSV调整.最终,通过模块级仿真验证、系统级虚拟仿真验证和FPGA原型验证完成了HSV调整电路的验证实现,验证结果表明本设计功能和性能满足需求,实现了流水处理的HSV调整功能,从而达到理想的视频图像处理效果.The rapid development of digital image processing technology requires more powerful and high performance graphics processors to provide support.In order to meet the requirement that the graphics processor can change a color attribute(hue,saturation or value)separately to adjust the video image display effect without affecting other attributes when video image processing is carried out in the RGB color space,this paper studies the design and implementation of an HSV adjustment circuit for pipeline processing.Key module includes RGB to HSV color space conversion,HSV adjustment and HSV to RGB color space conversion are adopted to design the circuit,especially realizing the core module HSV adjustment.Finally,The verification of HSV adjustment circuit is completed by module level simulation verification,system level virtual simulation verification and FPGA prototype verification,the results show that the design function and performance meet the requirements and realize the HSV adjustment function of pipeline processing,so as to achieve the ideal video image processing effect.
