摄影 数码相机 测量拍摄时滞、快门释放时滞、拍摄速率和启动时滞

[中文适用范围]： 本标准的目的是规定如何测量和报告数码相机（包括手机和平板电脑中的相机模块）的拍摄时滞、快门释放时滞、拍摄速率和启动时滞。该标准包括一种使用数码相机内部控制信号的方法和一种无需访问数码相机内部即可确定定时值的方法。 [外文原描述]： This document specifies how to measure and report the shooting time lag, shutter release time lag, shooting rate and start-up time lag for digital still cameras, including camera modules in phones and tablet computers. It includes a method that uses control signals inside the digital still camera and a method that determines the timing values without requiring access to the inside of the digital still camera. This document does not address the measurement either of auto focus speed below recommended illumination level or auto focus accuracy.
