Claim Text:
1. An endoscope system comprising: an optical endoscope including: a camera head configured to be attachable to and detachable from the optical endoscope and including an image pickup device that picks up the optical image transmitted by the image guide fiber bundle and generates a video signal; a video signal output section that is provided in the camera head and outputs the video signal generated by the image pickup device; a video processor that is configured such that the camera head is attachable to and detachable from, and processes the video signal; a video signal reception section that is provided in the video processor and receives the video signal outputted from the video signal output section; a moiré elimination section that is provided in the video processor and performs moiré elimination processing for eliminating moiré included in the video signal received by the video signal reception section, by means of image processing; a control section that is provided in the video processor and causes the moire elimination section to perform the moiré elimination processing; and an enhancement processing section that is provided in the video processor and performs image enhancement on the video signal, wherein the moiré elimination section is configured as a result that a filter coefficient to be used when the enhancement processing section performs image enhancement is replaced with a filter coefficient for moiré elimination, and the moire elimination section uses a processing circuit of the enhancement processing section as a processing circuit of the moiré elimination section itself, the camera head further includes a first identifier for identifying a type of the camera head, the video processor includes a first identifier detection section that detects the first identifier of the camera head connected to the video processor, and the control section causes the moiré elimination section to perform the moire elimination processing corresponding to a detection result of the first identifier.
