AS ISO 15781:2019 PDF
The objective of this Standard is to specify 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. This Standard 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 Standard does not address the measurement either of auto focus speed below recommended illumination level or auto focus accuracy.
This Standard is identical with, and has been reproduced from, ISO 15781:2019, Photography — Digital still cameras — Measuring shooting time lag, shutter release time lag, shooting rate, and start-up time lag.
