Image Quality Testing & Tuning

Image Quality Testing & Tuning

We provide different image quality testing and image quality tuning services that cover the tests needed in camera R&D chain. from camera module to final imaging product. We have access to a world class camera laboratory located in Tampere, Finland. This laboratory is part of a one of a kind image quality testing facility in the world. Furthermore, our software solutions enables cost effective testing due automated testing and reporting

The traditional way of doing image quality tuning is to start the tuning process when product prototypes are available (see Current in the picture below).
However, our image quality tuning process contains two steps:

  1. Camera module characterization and pre-tuning:
    We start image quality tuning work when camera and flash modules are available. In fact, camera and flash modules are tested in reference environment and the characterization results are then used to generate initial tunings.
  2. Full Tuning:
    After the product prototypes are available work continues by 3 more tuning steps: Mid Tuning, Fine Tuning and Final Tuning.


  • The best possible Image and video quality
  • Balanced performance
  • Camera tuning removed from the product program critical path

Valued Camera Experience

Valued Camera Experience (VCX) is an objective and unbiased image quality analysis of smartphone and other mobile device cameras.

This score is a numeric indicator of mobile phones and products and is based on an objective assessment of equipment and that does not contain any visual assessment or other subjective factors.

We can also provide VCX Score testing through a VCX certified trusted lab. Learn More!

List of additional services

  • Camera module Image Quality (IQ) characterization
  • Camera module spectral characterization (from 350nm to 1100nm)
  • Image quality tuning (TESTiLABS reference ISP/Customer specified ISP)
    • Image Quality Tuning provides the best image quality possible with camera module integrated to chipset or ISP. Camera module is characterized in the image quality laboratory and tunable ISP parameters are optimized according to Image Quality KPIs. Final adjustments are done by an experienced IQ-specialist taking customer preferences into account.
