An electrically-powered, hand-held digital electro-optical device designed to capture video or still image data for multiple medical applications (e.g., ophthalmoscopic, otoscopic, and dermatoscopic) using dedicated interchangeable lenses/attachments. It typically consists of a lightproof chamber with an aperture fitted with a lens and a shutter, through which the image of an object is projected onto a surface for recording. It may include a user display screen for visualization before image capture, and sometimes a docking cradle for battery recharging and connection to a personal computer.
