发明名称 VISIBLE TELEPHONE
摘要 A visible telephone includes a housing in which a video camera is accommodated in a manner that an aperture thereof is directed to the front. The camera is fixed to a rotatable holder which is rotated by an operation of a knob outside the housing, responsively, an angle of declination or elevation of the aperture of the camera is changed. The camera includes a lens system and a solid-state image sensor which converts a light image from the lens system into an electrical signal (video signal), which is mounted on a circuit board. The solid-state image sensor is responsive to at least an infrared light. On the same or the other circuit board, an infrared LED is mounted. The infrared LED is lightened at necessary timing to expose a person or subject in the front of the aperture of the camera.
