Abstract:
1. An endoscope device in which a portion of an optical system can be changed using an optical adaptor, the endoscope device comprising: an image pickup member configured for capturing an image that is input from the optical system, wherein the optical system is operable in at least two configurations including (i) a first configuration in which the optical adapter is combined with a reference scope, and (ii) a second configuration in which the optical adaptor is combined with a user scope; a first recording medium that records distortion parameters of the reference scope, the distortion parameters of the reference scope indicating optical properties of the reference scope; a second recording medium that records distortion parameters of the user scope, the distortion parameters of the user scope indicating optical properties of the user scope; and a distortion correcting member configured for correcting distortion in the image captured by the image pickup member when the optical system is operated in the second configuration, based on (i) optical data for correcting distortion in the optical system having the first configuration, (ii) the distortion parameters of the reference scope, and (iii) the distortion parameters of the user scope; wherein the second recording medium is provided inside the endoscope device, or is provided to an internal part of the user scope that is releasable from the endoscope device.
