Endoscope Distortion Correction Using Scope-Specific Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscope devices face challenges in accurately correcting image distortion due to differences in optical properties between the reference scope and the user scope, as the distortion correction parameters are created during production with a reference scope and do not account for the user scope's properties.
Innovation Solution
An endoscope device equipped with an image pickup member, a first recording medium for reference scope distortion parameters, and a second recording medium for user scope distortion parameters, allowing for distortion correction when the user scope and optical adaptor are combined, using optical data and distortion parameters to accurately account for the optical properties of both scopes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distortion correction is performed using optical data created with a reference scope, then the optical adaptor can be used with any user scope, but the distortion correction accuracy deteriorates due to differences in optical properties between reference and user scopes
Solution Approach 1:
The distortion correction process is segmented into two independent parts: reference scope distortion parameters (obtained during production) and user scope distortion parameters (obtained by capturing an image of a specific target). These segmented parameters are then combined to achieve accurate correction for the specific user scope while maintaining adaptor compatibility.
Solution Approach 2:
The system changes the distortion correction parameters dynamically based on the specific user scope being used. Instead of using fixed parameters from the reference scope, the system obtains and applies user-specific distortion parameters that reflect the actual optical properties of the connected scope, thereby improving correction accuracy.
2Ease of manufacture
If distortion correction parameters are obtained during production with a reference scope, then the production process is simplified, but the correction does not account for variations in user scope optical properties
Solution Approach 1:
The system performs preliminary action by obtaining user scope distortion parameters through capturing an image of a specific target before actual measurements are taken. This preliminary calibration step ensures that the distortion correction is tailored to the specific user scope, improving reliability without complicating the main production process.

AI summary
The present invention is an endoscope device in which a portion of the optical system can be changed using an optical adaptor, provided with: an image pickup member for capturing an image that is input from an optical system that incorporates a reference scope or user scope, and an optical adaptor; a first recording medium that records a first information that includes at least distortion parameters of the reference scope which indicate the optical properties of the reference scope; a second recording medium that records a second information that includes at least distortion parameters of the user scope which indicate the optical properties of the user scope; and a distortion correcting member that corrects distortion in the image captured by the image pickup member when the user scope and the optical adaptor are combined, based on the first information which is read out from the first recording medium and the second information which is read out from the second recording medium.
