PROBLEM TO BE SOLVED: To provide a scanning type co-focal endoscope system and a processor for a scanning type co-focal endoscope, capable of automatically setting suitable parameters used in exciting-light-control for reducing discoloration of fluorescent light.SOLUTION: A scanning type co-focal endoscope system includes: an optical fiber for emitting exciting-light to a subject optical fiber scanning means for spirally rotation-driving an emission end of the optical fiber light source control means for controlling exciting light on the basis of parameters a co-focal pinhole disposed at a position conjugative with a converging point of the exciting light an image signal detection means for detecting an image signal by receiving fluorescent light generated from the subject excited by the exciting light and image generation means for generating a co-focal image from the image signal. The light source control means changes the parameters on the basis of the co-focal image generated by the image generation means.
