Image processing unit for expanding endoscope image signal processing capability

Abstract

One expansion substrate or a plurality of expansion substrates that realize different facilities can be connected to a main substrate that realizes basic processing to be performed by a CCU. Based on an ID number produced by an ID generation unit mounted on a connected expansion substrate, a CPU incorporated in the CCU identifies the facility realized with the expansion substrate. A menu screen image presents item BOD Control under which the facilities are presented. When item BOD Control is designated, a BOD Control screen image that lists control items indicating the facilities realized with all the expansion substrates that are connected to the main substrate is displayed. When a concrete facility such as a P-in-P facility realized with an expansion substrate is selected or designated in the BOD Control screen image, a screen image concerning the designated P-in-P facility is displayed. Thus, the details of a facility that is realized with a connected expansion substrate can be set easily.
