So far, skin color has been measured only visually in most instances. Conventional colorimeters need contact with the examination area in order to eliminate the influence of the background illumination. We present an imaging colorimeter of non-contact skin color measuring system and some experimented results using such instrument. The system is comprised by a video camera, light source, a real-time image processing board, magneto optics disk and personal computer which controls the entire system. Both the camera and lamps are housed in a portable box. The CIE-L*a*b* uniform color space is used. In order to make the instrumental measurement of skin color clinical purposes practical, we studied the influence of some daily actions on skin color changing. The instrument is noncontact, easy to operate, and has a high precision unlike the conventional colorimeters. And the instrument should be portable and operate in normal hospital conditions. This instrument is useful for clinical diagnoses, monitoring and evaluating the effectiveness of treatment.
