A medical television system includes a television camera and a selector. The television camera includes a filter for separating visible light into three wavelength regions and transmitting near-infrared rays, and an image pickup element having sensitivity to both visible light and near-infrared rays. The selector selectively supplies the visible light separated into the three wavelength components or the near-infrared rays to the television camera.
