  • Endoscope apparatus
    Patent number: 6612981
    Abstract: Endoscopes comprise image pickup elements for picking up images and transmission circuits and the like for transmitting the picked up images with radio waves of different frequencies. In addition, bar codes to code the frequencies used for transmission are provided to the respective endoscopes, the bar code provided to the endoscope used in endoscope inspection is read on a receiver side, and a reception frequency of a station selection unit is set to the read frequency, so that a signal obtained by a desired endoscope can be easily received and imaged even in case a plurality of endoscopes are used.

  • Stereoscopic endoscope system
    Patent number: 6582358
    Abstract: A stereoscopic endoscope system includes a combined system of a stereoscopic endoscope unit and a camera unit. The stereoscopic endoscope unit has an insertion part and an observation part. The insertion part includes an objective lens and a relay lens in order from an object side, where the objective lens has a pair of first optical system and a second optical system which are arranged in parallel in an insertion direction, and a third optical system arranged in the insertion direction. The first optical system and the second optical system are for a stereoscopic vision observation, and the optical system has a viewing angle larger than that of the first and the second optical systems for observing a wider range than a that of the stereoscopic vision observation. The relay lens is arranged on the camera unit side of the objective lens.
