Abstract
A dermatoscope device is provided. The dermatoscope device includes an optical tube structure including an optical unit, which is provided to allow an observer to enlarge and inspect an observation target, and a light emitting unit which irradiates light to the observation target to be enlarged and inspected through the optical unit, a control module to control a form of irradiating the light through the optical unit, and a housing having the optical tube structure and the control module embedded therein.
