In this thesis , the image enhancement was also studied , such as dlti 、 dcti ( digital luminance 、 color transient improvement ) , peaking ( luminance peaking ) , ble ( black - level enhancement ) , brightness 、 hue 、 contrast and saturation adjustment , and then the hardware circuit was designed 研究了dlti (數(shù)字亮度瞬態(tài)增強(qiáng)) , dcti (數(shù)字色度瞬態(tài)增強(qiáng)) , peaking (亮度峰化) , ble (黑電平延伸) ,亮度、色調(diào)、對(duì)比度和飽和度調(diào)整等圖像增強(qiáng)技術(shù),并完成了圖像增強(qiáng)電路的設(shè)計(jì)。
