Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image recording systems for medical procedures face challenges in efficiently recording and retrieving specific scenes from long medical cases, requiring extensive search efforts when using recorded images for educational or certification purposes.
Innovation Solution
An image recording and reproduction apparatus that generates record data with chapter information based on operation signals from various devices and personnel, allowing for easy retrieval of desired scenes by associating chapter types with video signals and metadata.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If entire medical case is recorded for backup purposes, then complete medical case is preserved, but extensive search effort is required to find desired scenes
Solution Approach 1:
The patent divides the continuous medical case recording into discrete segments by inserting chapter marks at specific time points. Each chapter mark represents a meaningful scene or event boundary, allowing the complete medical case to be segmented into navigable sections. This segmentation enables quick jumps to specific scenes without searching through the entire recording.
Solution Approach 2:
The system performs preliminary action by automatically inserting chapter marks during the recording process based on pre-defined criteria or operator input. This preliminary structuring of the recording with chapter information allows for efficient navigation and retrieval later, eliminating the need for post-recording search efforts.
2Ease of operation
If chapter information is added during medical image recording, then desired scenes can be easily retrieved, but operation complexity increases
Solution Approach 1:
The operation instructor is designed to serve multiple functions: it can receive inputs from various sources (operator input device, scope switch, external device), determine the appropriate operation system, generate corresponding chapter information, and output it to the recording system. This multi-functionality reduces the need for separate dedicated devices for each function.
Solution Approach 2:
The operation instructor acts as an intermediary between the input devices (scope switch, operator input) and the recording system. It processes the inputs, determines the appropriate chapter information type, and mediates the transmission of this information to the recording apparatus, simplifying the overall system architecture.
3Adaptability or versatility
If multiple operation instructors are provided for different users, then user-specific chapter information can be added, but system complexity increases
Solution Approach 1:
The operation instructor is designed as a universal device that can handle inputs from multiple sources and serve multiple users. It can determine whether an input comes from an operator device or a scope switch, and generate appropriate chapter information accordingly. This universal design eliminates the need for separate dedicated instructors for each user or device type.
Solution Approach 2:
The operation instructor automatically determines the type of operation system and generates the appropriate chapter information without requiring manual configuration or intervention. It self-adjusts based on the input source (operator input device, scope switch, external device) and performs the chapter information generation autonomously.
Data Source
AI summary
An image recording and reproduction apparatus includes: a record data generation circuit configured to generate record data based on an inputted video signal; an operation input device configured to receive a signal generated based on an operation of one or more persons, for one or more operation instructors that accept an operation for adding chapter information to the video signal; an operation system determination circuit configured to determine at least one of the operation instructor generating the signal received by the operation input device, and a person performing the operation, and output a determination result; and a first processor configured to cause the record data generation circuit to generate the record data that associates the chapter information with the video signal, by generating chapter information of a chapter type based on the determination result of the operation system determination circuit, and supplying the information to the record data generation circuit.
