A camera for use in the medical field includes a housing having an entrance window. Arranged around the entrance window are white light emitting LEDs and UV emitting LEDs. These LEDs are arranged under regular pitch. Behind the entrance window there is a colour filter absorbing light generated by the UV-LEDs. The light transmitted by this colour filter reaches an image converter. In an evaluating circuit an underground image is removed, and the result is displayed on a monitor. |
