Video Processor Endoscope Zoom Mode Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processors for endoscopes with super-wide angle capabilities lack flexibility in electronic zoom processing, as they primarily focus on magnifying the forward visual field while omitting the sideward visual field, limiting the ability to switch between different zoom magnification factors and processing patterns efficiently.
Innovation Solution
A video processor that identifies connected endoscope types and enables electronic zoom processing with multiple magnification factors, allowing for two or three-step switching between different zoom modes, including a mode that alternates or cyclically switches between non-execution and magnification states, specifically designed for super-wide angle and single visual field endoscopes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If electronic zoom processing is applied to magnify the forward visual field region, then the visibility of the forward visual field is improved, but the sideward visual field region is omitted and overall visual field coverage deteriorates
Solution Approach 1:
The visual field is segmented into multiple regions (forward visual field region and sideward visual field region), and different processing patterns are applied to different regions. The image processing apparatus can selectively apply electronic zoom to the forward visual field region while preserving the sideward visual field region through pattern switching, allowing both regions to be optimally displayed according to the selected pattern.
2Adaptability or versatility
If multiple magnification factors are provided for electronic zoom processing, then the adaptability to different viewing needs is improved, but the complexity of operation and mode switching increases
Solution Approach 1:
The image processing apparatus implements periodic action through pattern switching, where processing patterns are cyclically switched based on input signals. The system can switch between different processing patterns (first processing pattern, second processing pattern, third processing pattern) that correspond to different magnification factors and display configurations, allowing automatic periodic transitions between zoom states without requiring complex manual intervention.
Solution Approach 2:
The system dynamically adjusts the processing pattern based on input signals and operational context. The image processing apparatus can switch between static and dynamic processing patterns, where the processing pattern is determined dynamically based on the combination of pattern selection signals and zoom operation signals, providing adaptability while maintaining ease of operation through automated decision-making.
3Adaptability or versatility
If the video processor is designed to support both super-wide angle endoscopes and single visual field endoscopes, then the versatility of the system is improved, but the device complexity increases
Solution Approach 1:
The image processing apparatus is designed with universal functionality to support multiple endoscope types (super-wide angle endoscopes and single visual field endoscopes). The system can adapt its processing patterns based on the connected endoscope type, using the same hardware platform to serve multiple functions. The processing pattern selection mechanism is configured to automatically or manually adapt to the specific endoscope type, eliminating the need for separate dedicated processors for different endoscope types.

AI summary
A video processor includes an identification section configured to identify a kind of an endoscope, an electronic zoom processing section configured to magnify by a first magnification factor and a second magnification factor larger than the first magnification factor, and a mode setting section configured to set to a first mode of enabling selection of a first processing pattern, and a second processing pattern, when connection of a super-wide angle endoscope is identified, and set to a second mode enabling selection of the second processing pattern when connection of a single visual field endoscope is identified, wherein when the mode setting section performs electronic zoom processing by the second magnification factor in the first mode, the electronic zoom processing section cuts out an image so that only the optical image of the forward visual field is displayed and magnifies the image with the second magnification factor.
