An endoscope processor comprising a touch-panel input unit, a mechanical switch unit, and a controller, is provided. The endoscope processor controls an endoscope system. The touch-panel input unit comprises a touch-panel monitor. A command to carry out a function of the endoscope system is input via a command-input display displayed on the touch-panel monitor. The mechanical switch unit is manipulated to carry out at least one function among a light-switching function, a pump-switching function, and a white-balance-start switching function. The controller carries out a function corresponding to the command input via the touch-panel input unit or the mechanical switch unit.
