  掃描儀的掃描速度

掃描儀的速度與系統配置，印畫冊掃描分彈率設置，掃描尺寸等有密切關系。

一般情況下，掃描黑白，印畫冊灰階圖像，掃描速度為2-10ms/1：掃描彩色圖像掃描速度為5-200m/1掃描速度和圖像質量之間有一定的矛盾。

一般情況下，人們總是希望掃描儀速度快，印畫冊但是掃描儀的工作方式是通過掃描儀的光源，利用一種色彩分離方法和電荷耦合器件（CD）陣列來採集被掃描對象的光信息，

它需要一定的時間來獲取圖像信息，印畫冊並將該信息傳輸到一個計算機圖像文件中去。因此，不是掃描儀的掃描速度越快越好，速度非常高的掃描儀，在掃描過程中。

可能會丟失一些掃描圖像信息。有些掃描儀在低解析度時掃描速度快，但在高解析度時掃描速度不一定快。印畫冊因此，必須在保證質量的前提下，提高掃描儀的速度。

此外，描儀還有其他一些指標，如掃描次數。印畫冊黑自掃描儀只有次掃描，彩色掃描儀可分為次掃描和卻早期的灰度掃描儀和彩色掃描儀是採用3次掃描。

隨著彩色CCD的推出，描儀的技術也隨之發展，3次掃描技術已趨於淘汰，目前彩色掃描儀一般為多次掃描。
