DIGITAL AND QUANTITAVE IMAGING BY CameraScan V3®-FrameScan V3®

Picture 1. CameraScan V3®-FrameScan V3® captures images using pre-set parameters and analyzes skin characteristics by comparing the images recorded at different times (T0, T1, T2, …).

The tool is of utmost quality: cosmetics applications require high sensitivity and reproducibility to allow the evaluation of their efficacy.
Hardware quality (resolution, homogeneous lighting, visio-bench, etc.), all  functionalities, metrological levels (quantitative and calibrated measurements) make the difference.
If images are not reproducible or their resolution is insufficient, a clear trend of the effect of the cosmetic product cannot be obtained even with the best image analysis software.

Hair brightness can be evaluated before and after the treatment as for resistance to hair dyes and coloring shampoos.
The image is processed by the software to quantify brightness improvement after the treatment.
