相機與手機鏡頭之檢測

Abstract

(1)目的: 現今照像科技發，達我們可以用簡單的測量工具，與簡單步驟，就以進一步了解手機或相機鏡頭的特性。以下介紹四個相機特性測量，暗角、鏡頭MTF、畸變與點素的測量。 (2)過程與方法: 利用一片校正板在距離120mm處針對所要量測的項目以相機分別拍 攝各種樣本，再利用小畫家觀察、分析他們的點數並記錄下來，再以 Excel跑出結果來觀察圖形進而了解相機之特性 (3)結果: 1.都有暗角，可憑四角亮度值判斷暗角現象嚴不嚴重， 2.可藉由MTF曲線知道相機解像力好壞， 3.可藉由畸變大小之道鏡頭會不會在角落失真 4.可以藉由點素量測知道一個點素的大小
