Endoscope Image Pickup Control Parameter Error Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopes with image pickup devices face challenges in accurately transmitting and reflecting control parameters for photographing control due to space limitations and signal processing complexities, leading to potential errors in brightness, shutter settings, and cutout ranges.
Innovation Solution
An image pickup system with a control apparatus and image pickup apparatus capable of communicating control parameters, including error detection codes, ensures that all control parameters are normally transmitted and reflected only when verified correct, preventing unintended changes and ensuring accurate photographing control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control parameters are transmitted from the control apparatus to the image pickup apparatus, then photographing control is enabled, but transmission errors may occur leading to incorrect settings
Solution Approach 1:
The patent implements a feedback mechanism where the image pickup apparatus transmits received control parameters back to the control apparatus for verification. The control apparatus compares the returned parameters with the originally transmitted ones to detect any transmission errors. This feedback loop ensures that parameter settings are accurately reflected only when transmission is verified as correct, resolving the contradiction between enabling control functionality and ensuring transmission reliability.
2Productivity
If control parameters are reflected in the image pickup apparatus, then photographing control is updated, but unintended changes may occur due to errors
Solution Approach 1:
The patent applies preliminary action by performing error detection and verification before the control parameters are reflected in the image pickup apparatus. The system transmits parameters, verifies their accurate reception through feedback comparison, and only then permits reflection. This preliminary verification step prevents unintended changes from occurring, ensuring that productivity gains from rapid control updates do not compromise parameter accuracy.
3Adaptability or versatility
If multiple control parameters are transmitted together, then integrated control is achieved, but error detection becomes more complex
Solution Approach 1:
The patent uses feedback to simplify error detection for multiple integrated parameters. Instead of implementing complex individual verification for each parameter, the system transmits all control parameters together, receives them back as a group, and performs comparative verification. This feedback-based approach maintains integrated control capability while avoiding the need for overly complex error detection mechanisms, as the bulk comparison is simpler than individual parameter validation.

Data Source
AI summary
An image pickup system is an image pickup system in which an image pickup device arranged at a distal end of an insertion section of an endoscope and a processor can communicate with each other. A group of multiple control parameters to be collectively transmitted and checksum codes related to the parameters are transmitted from the processor to the image pickup device, and the image pickup device reflects the control parameters on a register only when all the received multiple control parameters are normal, on the basis of the checksums.
