介紹了準高幀頻CCD 攝像機的一般概念及75 幀/ s CCD 攝像機輸出圖像的工作原理和主要性能指標。準高幀頻CCD 攝像機具有75 幀/ s 的圖像速度,除了適合于弱視閱讀機以外,還能在電視電影拍攝和相互轉換應用中起到積極作用;另外還能在電視監控準動態運動物體和交通監控系統中作為前端傳感器。由于能與PC 顯示器匹配,所以可應用到各學科研究領域的圖像分析儀中。
關鍵詞: 準高幀頻; 逐行掃描; M88DSP 數字圖像處理器
Abstract : Concept of quasi2high fram frequency CCD camera is described , and the principle and main specification of CCD camera to output 75 frame/ s is simply explained1 Its advantage and future application field are also introduced1Quasi2high framefrequency for CCD camera 74H0 has 75 frame/ s imaging rate. Besides being applied to the reading instrument of amblyopia , it can play an active part in taking pictures of the television and the film , and in transforming each other. In addition , it is the front sensor of CCTV for quasi moving object and the triffic supervisory system. Due to match with PC monitor , so it can also
apply to image analysis in scientific research fields.
Key words : quasi2high frame frequency ; progressive scanning ; M882DSP digital image processor
