Dermoscopy and skin imaging light sources: a comparison and review of spectral power distribution and color consistency

HIGHLIGHTS

SUMMARY

    Polarized light dermoscopy (technically cross-polarized) has been shown to improve the visibility of colors amongst other features. Some dermoscopes now integrate multispectral and colored LED, xenon, and UV sources into devices;17-20 however, most dermoscopes use white LEDs. Both SPD and color reflection can be measured quite precisely; however, despite these ever-advancing technical solutions for color vision, it is not possible to ensure that two individuals perceive the same colors identically, regardless of the accuracy of measurement devices. The CIE defines color rendering as "the effect of an illuminant on the . . .
