ABSTRACT:
A processing unit includes a positional relationship information extracting unit for extracting first information on a positional relationship of an optical adaptor by performing the image processing of a signal transmitted from an image pick-up unit upon capturing the image of a predetermined subject, a storing device for storing the first information on the positional relationship, a comparing and determining unit for comparing the first information on the positional relationship stored in the storing device with second information on the positional relationship which is extracted again by the extracting unit when replacing the optical adaptor by using the tip of an endoscope insertion portion, and a notifying unit for notifying a determination result based on determination information from the comparing and determining unit. Thus, it is possible to prevent the execution of measuring from deteriorating the precision by the change in positional relationship between an optical system of the optical adaptor and an image pick-up device.
