摘要
An endoscope for displaying a color picture image of an object to be visualized in a hollow cavity is disclosed. The endoscope comprises a sheath to be inserted into said hollow cavity and an exterior circuit. The sheath includes a self-scanning type solid state image pick-up device, a bundle of lead wires composed of a lead wire for supplying a signal for operating said image pick-up device from said exterior circuit and a lead wire for leading out a picture image signal supplied from said image pick-up device toward said exterior circuit, and an illumination light transfer body for transferring a light for illuminating said object to be visualized from said exterior circuit. The exterior circuit includes a circuit for generating a signal for operating said solid state image pick- up device, an amplifier for amplifying said picture signal supplied from said image pick-up device, a color Braun tube for displaying a color picture image upon receipt of said image signal from said amplifier, a light source for emitting an illumination light on said illuminating light transfer body, means for decomposing light incident on said illumination light transfer body into color lights and a signal change- over circuit for changing over a signal supplied to said Braun tube by a synchronizing signal.
