Smartphones that include compact camera modules (CCM) are the most popular imaging devices in the world. Their small size necessitates advanced sensor & lens technology and precise manufacturing.

Quality Standards

The v1 of the IEEE Camera Phone Image Quality standard (publication pending), defines seven test areas for objective quality analysis. By using viewing conditions to relating subjective human perception to objective quality metrics, this standard provides a set of metrics that strongly correlate with perceived image quality.

Testing Challenges

Part of the challenge of mobile device image quality evaluation is to test at macro distance, which necessitates a high precision test chart, and to test the cameras at long-range within the limited space of a factory environment.

Image Stabilization is a feature that is available on high-end mobile devices which can improve sharpness and low light performance by compensating for the motion of the photographer.

Manufacturing Testing

We work test-equipment makers who can provide turnkey solutions that include our chart and software components. Our paper: “Managing supply chain image quality” outlines many of the challenges that come along with high volume manufacturing.
