Abstract
A video processor which forms an endoscope apparatus is capable of selecting an image signal of a plurality of modes outputted from a signal processing circuit which performs signal processing with respect to an image pickup element of an endoscope, and image signals of a plurality of modes outputted from peripheral devices such as a VTR and the like, by a changing-over switch to output the image signals of the plurality of modes from a plurality of signal output ends. The plurality of output ends are connected to a plurality of input ends of an image display apparatus for performing image display. The image display apparatus is provided with a plurality of signal processing systems corresponding to the image signal of the mode inputted from the respective input ends, and is capable of selecting a single signal processing system by a changing-over switch to output the single signal processing system to a CRT. By operation of a changing-over operating switch on the side of the video processor, switching of the changing-over switch within the video processor is performed, and switching of the changing-over switch within the image display apparatus is also performed in interlocking relation thereto.
