Abstract
A portable imaging system incorporating a portable light source powered by a battery, the output of which is conditioned and regulated to supply an output voltage of a selected level such that the light source provides illuminating light of a selected illumination level and a selected color temperature for use in illuminating the area of interest of an object whose image is observed by means of said portable imaging system.
