De - noising of scanning signal based on wavelet transformation 基于小波變換的掃頻信號去噪處理
After being buffered , read by blocks and plus - width - modulating ( also called pwm ) , the digital video signal will be converted into scanning signal for color moving picture and then be outputted to the display board 系統將多媒體視頻卡輸出的數字視頻信號進行數據緩存、分塊讀取和脈寬調制等處理,形成符合顯示板結構的彩色運動圖像掃描信號,輸出到顯示板。
The pixel circuit can make oled emit light . continuously , while the peripheral driving circuit is designed to provide correct input signals for amoled , for instance , provide the line - by - line scanning signals for row electrode of oled matrix and the data 文中還將dvi ( digitalvisualinterface )接口引入和應用于外圍驅動系統當中,使視頻顯示電路同有源oled外圍驅動電路相接合,為amoled顯示屏提供了一個簡單實用的測試驅動平臺。
The run stm program includes the control of scanning signal , supervise and control the running state , set the scan range , set parameters , set and acquire the clock , collect and save the image signal , etc . image manipulation functions includes : on the space of the wipe of speckle , smooth image , blur , step sharp image , laplace sharp , and automatically adjust contrast , etc Stm運行程序包括掃描信號控制、運行狀態(tài)監(jiān)控、設置運行參數,設置并獲得時基、圖像信號采集存取等等。圖像處理功能包括在空間域上的去斑、圖像平滑、模糊、圖像的梯度銳化、拉譜拉斯銳化,對比度自動調整等等功能,在頻域空間上完成數字圖像的傅立葉變換,并討論了理想高低通濾波。
Current tv system has two types : one is the 60hz based system , the other is the 50hz . the phenomenon of large area flicker is not obvious in the 60hz based system , so the scanning converter uses the way of converting the 60hz and 50hz based interlaced scanning signal to 60hz based progressive scanning signal . employing this way the converter can not only reduce the large area flicker and interline twitter , but erase the raster and display finer and smoother pictures 現行的電視制式有60hz和50hz系統兩種,在60hz系統里,大面積閃爍不是很明顯,因而本掃描轉換器采用將60hz和50hz的隔行掃描信號統一處理成60hz的逐行掃描信號的方法,這樣可一方面使大面積閃爍和行間閃爍都比較輕,又可消除行結構,重現細膩圖像。
