Standards

International standards groups such as IEEE, ISO, IEC and ICC, work towards the betterment of imaging science and to advance standard practices. These committees are comprised of international imaging experts from a wide array of specialized fields. Each member brings a unique perspective to the collective experience and insight of the boards.

Standards are designed to make independently obtained test results comparable, which ensures metrics are consistent across vendors. Companies that adhere to standards benefit from increased oversight and traceability.

ISO: International Organization for Standardization

ISO is an independent international organization that brings together experts to share knowledge and develop voluntary, consensus-based, market relevant International standards that support innovation and provide solutions to global challenges.

ISO TC 42 WG 18: Digital Still Photography

This group is responsible for developing and publishing objective standards related to the valuation of digital still photography, including DSLR, mobile, security cameras, and much more (video and video standards not included). Working Group 18, along with ISO as a whole, defines methodologies and best practices and does not set minimum standards or requirements for image quality testing. Learn more about ISO TC42, working group 18. Imatest implementation of ISO standards include:

  • ISO 12233 for photography and electronic still picture imaging, resolution and spatial frequency
  • ISO 12232 for ISO, speed rating, standard output sensitivity, and recommended exposure index
  • ISO 15739: Noise and dynamic range
  • ISO 14524: Tone curve OECF standard
  • ISO 17850: Geometric distortion
  • ISO 17957: Uniformity/shading measurements
  • ISO 18844: Stray Light (Flare)
  • ISO 19084: Chromatic displacement
  • ISO 19567: Texture reproduction – partial support

ISO TC 22 Road Vehicles SC 35: Lighting and visibility

  • ISO 16505: Automotive side-mirror replacement system standard (partial support) 

ISO TC 172 SC 5: Microscopes and endoscopes


IEEE-SA: Institute of Electrical and Electronics Engineers Standards Association

IEEE-SA is the world’s largest professional association, advancing innovation and technological excellence for the benefit of humanity (IEEE Mission and Vision).

IEEE 1858 CPIQ: Camera Phone Image Quality

The Camera Phone Image Quality (CPIQ) standard seeks to standardize image quality test metrics and methodologies across the industry, correlate objective test results with human perception, and combine this data into a meaningful consumer rating system. The majority of consumers are unsure how to judge and compare device image quality. CPIQ serves as a way to assess and communicate image quality and dispel the myth that more megapixels correlate with better image quality.

IEEE P2020: Automotive System Quality Working Group

The P2020 working group was established in 2016 to produce standards for Automotive applications.  The metrics include Flicker, Contrast Perfirmance Indicator (CPI), Dynamic Range, Resolution Stray Light (Flare) and Geometry.


IEC: International Electrotechnical Commission

IEC-62676 – Video surveillance systems for use in security applications


ICC/CIE: International Color Consortium

ICC and CIE focus on the standardization of color characterization and calculation. Results of their work include a standardized cross-platform device profile format, ICC profiles, the CIELAB color space, and most color difference characteristics.

EMVA: European Machine Vision Association

 EMVA-1288: Standard for Measurement and Presentation of Specifications for Machine Vision Sensors and Cameras.
