Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical observation systems face challenges in maintaining continuous image display during signal transmission failures, often requiring redundant signal paths that complicate the structure and do not ensure seamless observation until the failure is resolved.
Innovation Solution
A medical signal processing device distributes pixel data groups across multiple signal transmission paths, ensuring that most significant digit data of adjacent pixels is included in different distributed image signals, allowing for continuous display even if one path fails, without the need for redundant paths when no failure occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant signal transmission paths are provided to ensure continuous image display during transmission failure, then reliability is improved, but device complexity increases
Solution Approach 1:
The image signal is segmented into multiple distributed image signals, where each signal contains pixel data from different spatial locations. This segmentation allows the system to transmit divided image information through multiple paths simultaneously, enabling continuous display even when one path fails, without requiring complete redundant paths.
Solution Approach 2:
Different distributed image signals are allocated to different transmission paths based on their spatial characteristics. Each transmission path carries a specific portion of the image data, allowing the system to optimize transmission for each path while maintaining overall image integrity through local quality distribution.
2Reliability
If identical image signals are transmitted through multiple signal transmission paths to ensure continuous display, then reliability is improved, but device complexity increases due to redundant paths
Solution Approach 1:
Instead of transmitting identical complete image signals through multiple paths, the invention segments the image signal into distributed portions and transmits them through multiple paths. This approach provides fault tolerance through diversity while avoiding the redundancy of complete duplicate signal transmission.
Solution Approach 2:
The conventional approach of transmitting identical signals is inverted by transmitting different segmented portions of the same image through multiple paths. This inversion achieves the same reliability goal but with more efficient use of transmission resources and reduced structural complexity.

AI summary
A medical signal processing device processes an image signal received in accordance with a result of examining inside of a subject. The image signal includes pixel data groups that are data of respective pixels different from each other and received by the medical signal processing device in parallel. The medical signal processing device includes a distribution processing unit configured to generate distributed image signals by distributing the pixel data groups, and the distribution processing unit distributes the pixel data groups such that, among the pixel data groups, pieces of data at bit positions of most significant digits of the pixel data groups of pixels adjacent to each other are included in the respective distributed image signals different from each other. The distributed image signals are transmitted to an external medical control device through respective signal transmission paths.
