Patent ID: 8885033

Claim:
An endoscope system comprising: a light source apparatus comprising a first light-emitting device that generates light of a first color, a second light-emitting device that generates light of a second color different from the first color, a failure detection section that detects which color light-emitting device fails in the first light-emitting device and the second light-emitting device, and a light source control section that controls, when a failure of the first light-emitting device or the second light-emitting device is detected by the failure detection section, the first and second light-emitting devices to generate illumination light by the light-emitting device other than the light-emitting device for which the failure is detected in the first and second light-emitting devices; an endoscope that irradiates a subject with illuminating light generated by the light source apparatus and takes in an optical image of the subject; an image pickup device that picks up an image of the optical image of the subject; a video processor that processes the image picked up by the image pickup device; a selecting section that selects, based on a detection result by the failure detection section, image processing in the video processor from among color image processing corresponding to a state in which a failure does not occur in the first and second light-emitting devices, first image processing corresponding to a failure of the first light-emitting device, and second image processing corresponding to a failure of the second light-emitting device; and a monitor that displays the image subjected to the image processing selected by the selecting section.
