Imatest is pleased to announce their partnership with Sofica, a group of camera algorithm validation and test automation experts based in Finland. This partnership will bring mobile device customers a revolutionary, robot-aided R&D test automation system integrated with Imatest analysis software and test charts.
What is CPIQ?
IEEE-SA working group P1858 created the CPIQ standard. CPIQ seeks to standardize image quality test metrics and methodologies across the mobile device industry, correlate objective test results with human perception, and combine this data into a meaningful consumer rating system.
CPIQ serves as a way to assess and communicate image quality to the vast majority of consumers who are unsure how to judge and compare device image quality.
Imatest is pleased to announce the release of version 4.4, which includes the following features:
Support for all 2016 Camera Phone Image Quality (CPIQ) standard metrics for mobile device image quality. CPIQ serves as a way to assess and communicate image quality to the vast majority of consumers who are unsure how to judge and compare device image quality. See a full CPIQ overview.
FiveFocal Imager software allows the user to virtually prototype cameras and imaging systems. Imager’s sophisticated models accurately simulate a complete imaging system, including scene, lens, sensor, and signal processing. Imager allows you to understand the performance and limits of a camera system before building an expensive physical (more…)

Main features include:
- Support for all CPIQ metrics for 2016 international standards for mobile device image quality.
- Autofocus, Auto White Balance, and Auto Exposure metrics for faster image adjustments.
- Additional controls for Image Sensor (IS) device management.
- Concurrent network licensing adds flexibility for shared work environments.
- Image processing module to assess the effect of standard image processing algorithms on image quality.
Imatest now offers the Artograph LED Lightpad Series as an inexpensive, lightweight, and compact way to illuminate your transmissive test charts.
These light sources work well for MTF and resolution measurements with Imatest transmissive test charts (SFRplus and eSFR ISO). They also offer advantages for testing ultra-wide angle camera systems with transmissive SFRreg targets, where uniform illumination can be difficult to achieve with reflective charts.
Imatest is pleased to announce our partnership with isMedia, a specialist in building digital imaging test machines and custom test solutions. This partnership will provide customers with a wide range of highly customizable test machines capable of extensive image quality analysis on manufacturing lines.
The Sinusoidal Siemens Star test chart allows you to measure MTF and limiting resolution with a chart that provides angular response and may be less affected by signal processing (especially sharpening) than slanted-edges. Siemens star MTF20 (the spatial frequency where MTF is 20% of its low frequency value) is a good estimate of limiting resolution. (more…)
