解釋
亮度級-
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 （數字亮度瞬態增強） ， dcti （數字色度瞬態增強） ， peaking （亮度峰化） ， ble （黑電平延伸） ，亮度、色調、對比度和飽和度調整等圖像增強技術，並完成了圖像增強電路的設計。 -
In improved uep scheme, the syntax elements belonged to luminance parts and chrominance parts was reassigned to different data partitions. those packets containing syntax elements belonged to luminance parts were got error protection at high level so as to guarantee their correctness during transmitting in error - prone network. simulation has shown that using proposed scheme, the packing tradeoff is decreased 8240 bytes in error - free channel and also the output bits and bit rate of coded video stream are decreased 2. 70kbits and 0. 33 kbps respectively
模擬實驗表明，本方案能在無噪通道中有效降低編碼器端8240位元組的打包開銷和2 . 70kbit的輸出比特數以及0 . 33kbps的比特率，而在有噪通道中可使解碼輸出重構視頻圖像的視覺質量得到一定程度的提高，亮度分量峰值信噪比可增加近1db 。 -
Because spca720a does n ' t support float calculation itself, and the color level and the luminance level of every point on tv screen is related with the other 4 point around it, it ' s hard to draw curve and slash. in fact, we choose to draw vertical line and horizontal line the approximate the curve and slash
由於spca72oa本身不支持浮點數運算，並且tv中的每個點與它的色度和周圍的4個點的亮度有關，畫曲線和斜線比較難于實現，所以在實際實現中，我們用畫水平線和垂直線來近似曲線和斜線。 -
In this paper, the digital image real - time processing system was a very important part of fed driving circuit system. altera fpga chip was used to complete operation on reading and writing and timing control of fed image data. the image process algorithms mainly used gray - level transformation in the theory of image enhancement, and the algorithm realized luminance non - uniformity control, gray - level non - linear correction and automatic power control for fed
本文設計的基於fpga技術的數字圖像實時處理系統是fed驅動系統中的重要組成部分，其核心部分採用了altera公司的fpga晶元，實現對fed圖像數據讀、寫操作和時序控制等，而圖像處理的演算法部分主要是利用圖像增強技術理論中的灰度變換方法，實現對fed的亮度非均勻性控制、灰度非線性校正以及fed的自動功率控制。
