中文摘要 |
由於數位相機日益普遍,使得愈來愈多的使用者接觸攝影,對於一個拍攝影像的品質也逐漸受到重視,本篇文章就針對影像品質評估作探討,以銳利度為研究的項目,進行SFR(Spatial Frequency Response)以及MTF (Modulation Transfer Function)的測試。本篇文章分為兩部份,第一部分先做文獻的名詞解釋,來了解一些相關名詞的意義;第二部份則是進行一項實驗,進行數位影像的MTF測試,以Imatest 2.5.5 Pro此軟體來進行實驗,並將實驗結果記錄下來,最後將實驗結果整理分析成為本篇研究結論。 |
英文摘要 |
Because the digital camera is becoming popular, it makes more and more users contact photography, the image quality is also important to them. This article assesses and does the discussion to image quality, regard sharp degree as the project studied, the study carried on SFR (Spatial Frequency Response) and MTF (Modulation Transfer Function) Test. This article is divided into two components, Part one Make the explanation of nouns of the literature first, come to understand the meanings of some relevant nouns; the second component is to carry on an experiment about MTF test of the digital camera, I use Imatest2.5.5 Pro to carry on the experiment, and write down the experimental result. Finally, I recorded the experimental result in order to analyze the studies and define the conclusion. |
