Refresh rate: The number of times per second in which the monitor draws the data it is being given. Since activated LCD pixels do not flash on/off between frames, LCD monitors exhibit no refresh-induced flicker, no matter how low the refresh rate.[4] Many high-end LCD televisions now have a 120 or 240 Hz (current and former NTSC countries) or 100 or 200 Hz (PAL/SECAM countries) refresh rate. The rate of 120 was chosen as the least common multiple of 24 frame/s (cinema) and 30 frame/s (NTSC TV), and allows for less distortion when movies are viewed due to the elimination of telecine (3:2 pulldown). For PAL at 25 frame/s, 100 or 200 Hz is used as a fractional compromise of the least common multiple of 600 (24 x 25). Until a 600 Hz refresh rate becomes available, PAL video will speed up cinema by a small percentage (currently 1 to 4 percent). These higher refresh rates are most effective from a 24p-source video output (e.g. Blu-ray Disc), and/or scenes of fast motion.
我也不是專門...
所以自己看wiki...
LCD的reflash rate跟CRT的有點不同...
翻譯沿用"掃描"頻率好像不太對...
成像原理不同的關係...
LCD的reflash rate直接影響的應該是反應時間...
而影片的fps(通常是24/30)和螢幕的reflash rate並不是一致的...
所以要作轉換...
裡面還有telecine要考慮的問題...
那段說明很簡略...不過我大概看懂他要說些什麼...
只是很模糊而已...
有興趣的可能要從傳統電視成像的原理開始K了...(汗

錄製100fps的影片要放應該也可以啊...
LCD的reflash rate到100Hz理論上應該就可以了吧?...
前提是不用考慮telecine這些煩人的東西...
