标准范围

This International Standard specifies how to measure and report the shooting time lag, shutter releasetime lag, shooting rate, and start-up time for digital still cameras including camera modules in phonesand tablet computers. It includes a method that uses control signals inside the digital still camera and amethod that determines the timing values without requiring access to the inside of the digital still camera.Depending on the method used to start the timing device, there can be a time lag between the activationof the timing device and the closure of the exposure switch of the digital still camera.This International Standard does not address the measurement of auto focus accuracy and speed at lowlight conditions.For digital still cameras that continuously shoot images into the buffer, the exposure button only acts asa selector of an image that was taken before the exposure button was pressed. The methods to measureshutter time lag and shooting time lag do not address this case and cannot be used for this type of digitalstill camera.
