Abstract [en]

The ability of the computer screen photo-assisted technique (CSPT) to evaluate color samples through its light transmittance profiles is demonstrated by using liquid crystal displays (LCD) as light sources. Transmittance profiles are more drastically affected by angular dependencies than those obtained with CRT illumination. A local light reference computation is introduced to counteract this effect yielding equivalent profiles for both kinds of displays thus allowing for a broader universe of platforms to perform CSPT experiments, including mobile devices.
