Title
Consumer Camcorder or Video Camera Low Light Performance

Consumer Electronics Association

Publication Date:
Sep 1, 2003

Scope:

Purpose

The purpose of this document is to specify the recommended method and test conditions to determine the low light sensitivity of consumer camcorders¹ 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.

Applicability

This specification applies to camcorders designed with gamma correction for both luminance and chroma channels. The camcorder shall be capable of operation under a wide range of light color balance conditions including incandescent, fluorescent and outdoor lighting.

Reference to this standard in manufacturer's published specifications or advertisements of low light sensitivity will imply that all production units of that model meet or exceed the published values.

In addition, the low light performance will be determined on the video camera section only. This specification will not be used to determine low light performance from a playback tape. For camcorders that do not provide a baseband video output from the camera video section, the manufacturer will be required to provide an adapter circuit with a 75 O baseband video output.

¹ For the purpose of this document, the terms "camcorder", "video camera", and "camera" will be used interchangeably.
