Voluntary Standards Cover the Spectrum: from Automatic Ice Makers to Camera Phone Image Quality

8/30/2017
ANSI News

In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute (ANSI) publishes snapshots of the diverse standards initiatives undertaken in the global and national standards arena, many of which are performed by ANSI members and ANSI-accredited standards developers. Two of the latest selections follow:

Camera Phone Image Quality

As camera-equipped mobile devices replace digital cameras for their convenience and synchronizing capabilities, customers often have little or no guidance about the quality of images that are produced by particular device models. According to IEEE, the lack of guidance is due, in part, to "a lack of uniform image quality testing for the devices, and what testing is done seldom is accessible to the layperson."

IEEE 1858-2016, IEEE Standard for Camera Phone Image Quality, covers quantifying the performance of camera-equipped mobile devices, with an emphasis on metrics and procedures appropriate to the types of sensors, lenses, and signal processing routines present on such devices.

The document is not intended as a general image quality standard for photographs produced by high-end dedicated cameras, e.g., DSLRs. Metrics include spatial frequency response, color uniformity, chroma level, lateral chromatic displacement, local geometric distortion, texture blur, and visual noise.

An ANSI member and accredited standards developer, IEEE is a nonprofit organization that develops and publishes standards relating to electronics.
