✦ Synopsis

SolarScane is a prototype real time diagnostic instrument, which uses image analysis to detect malignancy of melanocytic skin lesions. It employs dermatoscopy as an imaging technique and is built around a 3-CCD analogue video camera. In order to obtain the image of maximum quality for the analysis the operator should be noti®ed about the problems with the image captured. This allows the operator to rectify the problem and re-capture the image. Detectors for 2 type of the acquisition-time problems are described: the interlaced video camera ®eld misalignment artefact and excessive specular re¯ection artefact caused by insuf®cient amount of oil used for dermatoscopic immersion of the lesion imaged.
