The present invention provides an endoscope image processing device that processes a normal-light image of a subject illuminated with broadband visible light and a special-light image of the subject illuminated with narrow-band special light, the endoscope image processing device including: a non-structure reducing unit that reduces non-structure information having no correlation with the structure of the subject, in the special-light image； a superimposed-image generating unit that generates a superimposed image by superimposing the special-light image in which the non-structure information has been reduced, on the normal-light image； and an output unit that outputs the superimposed image to an external device.
