ENDOSCOPE SYSTEM

摘要

An endoscope system includes: an image pickup apparatus in which an insertion portion is detachable, the image pickup apparatus picking up an optical image of light from an observed object; a focus changing section that can change focus of the image pickup apparatus; a control section that generates a control signal to control the optical image in a focused state in a state in which the insertion portion is fitted to the image pickup apparatus; a storage section that stores data associating a type of the insertion portion and control information; an identification section that reads a predetermined code to identify the type of the insertion portion; and an optical characteristic acquiring section that acquires the control information corresponding to the type of the insertion portion identified by the identification section to acquire an optical characteristic of the insertion portion used to generate the control signal.

1. An endoscope system comprising:
an image pickup apparatus in which an insertion portion comprising an objective optical system is detachable, the image pickup apparatus being configured to pick up an optical image of light from an observed object transmitted by the objective optical system of the insertion portion and to output the optical image as an image pickup signal; a focus changing section provided in the image pickup apparatus and comprising a drive section that can change focus of the image pickup apparatus; a control section configured to generate a control signal by using an optical characteristic of the insertion portion to automatically control the optical image in a focused state for the drive section of the focus changing section in a state in which the insertion portion is fitted to the image pickup apparatus; a storage section storing a database including a plurality of data associating a type of the insertion portion and control information including the optical characteristic of the insertion portion; an identification section that reads a predetermined code included in a picked up image to identify the type of the insertion portion when the image pickup apparatus picks up the image of the predetermined code displayed on an outer surface of the insertion portion; and an optical characteristic acquiring section configured to acquire the control information corresponding to the type of the insertion portion identified by the identification section from the database to acquire the optical characteristic of the insertion portion corresponding to the type of the insertion portion identified by the identification section, the optical characteristic serving as the optical characteristic of the insertion portion used by the control section to generate the control signal.
