Solution Overview
Problem
Endoscope systems face challenges in accurately correcting pixel defects and characteristics of imaging elements during shipment and use, leading to variations in image quality due to the lack of effective management and updating of correction information.
Innovation Solution
An endoscope system with an imaging apparatus that outputs electrical signals from designated pixels, connected to a processing apparatus and a management server for bi-directional communication, allowing for the recording and updating of identification and correction information to ensure accurate pixel correction and management of imaging element characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If correction information is recorded only in the imaging apparatus, then the imaging apparatus can perform pixel correction, but the correction information cannot be updated when imaging elements are replaced
Solution Approach 1:
A management server is introduced as an intermediary between the imaging apparatus and the external environment. The management server stores correction information in its database and manages updates when imaging elements are replaced. The imaging apparatus communicates with the management server to acquire and update correction information, ensuring continuous availability of accurate correction data without requiring physical access to the imaging element's internal memory.
2Reliability
If correction information is stored in a management server database, then central化管理 is achieved, but communication protocols and data management complexity increase
Solution Approach 1:
Correction information is pre-stored in the management server database before imaging elements are installed or replaced. When an imaging apparatus is connected, the system performs preliminary verification to determine whether correction information exists in the database and automatically acquires it if available, avoiding the need for complex real-time generation or manual configuration protocols.
Solution Approach 2:
The imaging apparatus sends identification information to the management server, which responds with appropriate correction information. This feedback mechanism automates the correction information acquisition process, reducing the need for complex manual configuration protocols while ensuring the imaging apparatus receives the correct correction data for its specific imaging element.
3Manufacturing precision
If imaging elements are corrected during shipment, then initial pixel defects are addressed, but correction information may become outdated when elements are transferred between systems
Solution Approach 1:
The correction information management system is designed to be dynamic rather than static. The management server database can be updated with new correction information, and imaging apparatuses can periodically acquire updates. This dynamic approach ensures that correction information remains valid and accurate even as imaging elements are transferred between different systems or over time, extending the effective duration of correction information validity.

Data Source
AI summary
An endoscope system includes an imaging apparatus that outputs, as image information, an electrical signal photoelectrically converted from a plurality of pixels, outside the imaging apparatus, and a processing apparatus that is connected to the imaging apparatus so as to bi-directionally communicate with the imaging apparatus. The imaging apparatus includes a first recording unit that records identification information for identifying the imaging apparatus. The processing apparatus includes a second recording unit that records correction information for correcting characteristics of the imaging apparatus in association with the identification information, and a control unit that acquires, from the second recording unit, the correction information corresponding to the identification information received from the imaging apparatus and transmits the correction information to the imaging apparatus.
