CPIQ – Camera Phone Image Quality Standard

IEEE-SA Working group p1858

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.

Experts from over 20 companies and a range of industries, including mobile, OS, chipset and handset manufacturing, and test software, are committed to creating these metrics. In order to maintain consistency across different organizations, CPIQ maintains a liaison relationship with the International Organization for Standardization (ISO).

Imatest Version 4.4 supports all CPIQ v1 measurements:

Future revisions of the standard that are under development will cover white balance, autofocus, video quality, dynamic range and many more relevant image quality factors.

The IEEE-SA Conformity Assessment Program (ICAP) leverages IEEE standards development processes by extending standard lifecycles and advancing and accelerating market adoption (IEEE – ICAP). The program verifies that test labs have the proper equipment and test procedures in order to comply with the IEEE standard.[b]

The Conformity Assessment Steering Committee (CASC), under ICAP, creates the consumer rating system for CPIQ and advises on test methods and interpretation of the standard, among other things. Learn more about CASC at: standards.ieee.org/about/icap/cpiq.html
