Observation System Adaptive Light Control for Flickering Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination systems for medical observation devices, such as endoscopes and ring lights, often lead to erroneous selection of illumination light due to differences in application, causing incorrect light emission settings that may result in flickering perceived by operators or affect human vision.
Innovation Solution
An observation system with a control device that acquires irradiation environment information to differentiate between open field and closed field environments, displaying specific software keys for light emission control, enabling or disabling functions related to flickering light emission based on the environment, ensuring appropriate light emission settings for image observation and medical illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a light source device is made connectable to multiple devices (illumination device for image observation and medical illumination device), then the adaptability and versatility of the light source device is improved, but the risk of erroneous selection of illumination light increases and the reliability of the system deteriorates
Solution Approach 1:
The control device determines the connection state between the light source device and either an illumination device for image observation or a medical illumination device before allowing light emission control. This preliminary determination prevents erroneous selection by establishing the correct operational mode in advance based on what device is connected
Solution Approach 2:
The system provides feedback to the user interface about the determined connection state, indicating whether the light source device is connected to an illumination device for image observation or a medical illumination device. This feedback mechanism guides appropriate operation and prevents incorrect selection
2Productivity
If blinking light is used as illumination light to shorten charge storage period and increase transfer rate, then the productivity of image capture is improved, but flickering may be perceived by operators when the light enters their eyes
Solution Approach 1:
The system changes the frequency parameter of the blinking light based on the connection state. When connected to an illumination device for image observation, blinking light at a frequency that may cause flicker is used to improve image transfer rate. When connected to a medical illumination device, the frequency is adjusted to a range that prevents flicker perception while maintaining adequate illumination
