The purpose of this document is to specify the recommended method and test conditions to determine the low light sensitivity of consumer camcorders operating on the North American 525 line, 60 Hz NTSC color video standard. Utilizing standard engineering video test equipment, test charts and simple adjustable lighting, the low light sensitivity of consumer-grade camcorders will be determined. The low light sensitivity of the unit under test will be expressed in lux.
