曝光补偿

利用该功能可以以有限的增量快速调整相机测定的曝光值,从而提 高照片的曝光度。设置曝光补偿为 -1.0 EV 可将值进一步调暗或设置 曝光补偿为 1.0 EV 可将值进一步调亮。

Exif(可交换图像文件格式)

该规范是由日本电子工业发展协会 (JEIDA) 创立的,旨在为数码相 机定义图像文件格式。

曝光

允许进入相机感光面的光量。曝光受到快门速度、光圈值和 ISO 感 光度组合的控制。

闪光灯

利用该快速闪光有利于在低照度条件下进行充分曝光。

焦距

从镜头中心到其焦点的距离(以毫米为单位)。较长的焦距导致视 角较窄且拍摄对象放大。较短的焦距使视角变宽。

图像传感器

数码相机中包含图像中每个像素各自的像点的物理部件。每个像点 记录着曝光时射到该点的光线的亮度。普通的传感器类型有 CCD (电耦合元件)和 CMOS(互补金属氧化物半导体)。

ISO 感光度

相机对光线的敏感度,与胶片相机中使用的胶片速度等同。ISO 感 光度的设置越高,相机可使用越快的快门速度,这样可以减少由于 相机抖动和光线不足引起的模糊。然而,影像的感光度越高就越容 易产生噪点。

JPEG(联合图像专家组)

数码影像的有损压缩方式。压缩成 JPEG 图像时,在尽可能避免降 低图像分辨率的同时降低图像的整体文件大小。

LCD(液晶显示屏)

电子消费品中广泛使用的一种的视觉显示屏。该显示屏需要独立的 逆光,如 CCFL LED 来再现色彩。

微距

利用该功能可以拍摄微小对象的近距离照片。使用微距功能时,相 机可以对微小对象以接近实物的比例(1:1)进行鲜明的对焦。
