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几近实物的比例(1:1)进行鲜明 的对焦。

测光

测光是指相机测量曝光光量的方法。

MJPEG(联合活动图像专家组)

一种压缩为 JPEG 图像的视频格式。

噪点

数码影像中的可能显示为位置错误或随机的明亮的错误像素。 当相机以高感光度拍摄照片、或以在黑暗场所自动设置的感光 度拍摄照片时,容易产生噪点。

光学变焦

这是一种可以用镜头放大影像而不降低影像画质的普通变焦。

画质

数码影像中使用的压缩率的一种表达方法。画质越高的影像, 压缩率越低,通常文件也就越大。

分辨率

数码影像中显示的像素数。高分辨率的影像含有更多的像素, 而且通常会比低分率的影像显示更多的细节。

快门速度

快门速度是指打开和关闭快门所需的时间。因为它控制光量到 达图像传感器之前通过光圈的光量,因此是控制相片亮度的重 要因素。较快的快门速度允许光进入的时间较短,相片会较 暗,可以更容易定住运动中的拍摄对象。
