What is this BS EN 61146-3 - Non-broadcast camera recorders about?
BS EN 61146-3 discusses video cameras (PAL/SECAM/NTSC) and methods of measurement with a focus on non-broadcast camera recorders. BS EN 61146-3 is the third part of the BS EN 61146 multi-series on video cameras that describes a measuring method that concerns the assessment of the performance of non-broadcast camera recorders (NTSC/PAL/SECAM).
The appropriate measurements are to be applied according to whether the camera-recorder has a tube or semi-conductor camera. In the case of a camera recorder without playback capability, the details of the separate player used for the measurements shall be stated. In BS EN 61146-3, the characteristics apply to the camera-recorder as a complete entity.
Note: BS EN 61146-3 does not specify limiting values for various parameters.
Who is BS EN 61146-3 - Non-broadcast camera recorders for?
BS EN 61146-3 on non-broadcast camera recorders is useful for:
- Manufacturers of digital cameras
- Optical engineers
- Image Quality researchers
Why should you use BS EN 61146-3 - Non-broadcast camera recorders?
A camera-recorder is a combination of several devices, such as a video camera, video recorder,
microphone and an electronic or through-the-lens (TTL) viewfinder. BS EN 61146-3 defines test patterns and measurement conditions so as to enable the comparison of the results of measurements.
BS EN 61146-3 describes a measurement method that is designed to enable the assessment of the performance of the camera-recorder by using the lens for input and any available output from the device (e.g., separate luminance and chrominance signals or composite signal output). In conclusion, the test method described in BS EN 61146-3 helps you identify the performance levels of non-broadcast camera recorders and can be used for quality assurance purposes.
