介紹了準(zhǔn)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(biāo)。準(zhǔn)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(zhuǎn)換應(yīng)用中起到積極作用;另外還能在電視監(jiān)控準(zhǔn)動態(tài)運動物體和交通監(jiān)控系統(tǒng)中作為前端傳感器。由于能與PC 顯示器匹配,所以可應(yīng)用到各學(xué)科研究領(lǐng)域的圖像分析儀中。

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
