Medical Image Recording Control Prioritizing Video Sources by Light State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In surgical operations, managing multiple video sources such as room cameras, surgical cameras, and laparoscopes to prioritize and efficiently record high-quality video signals while optimizing storage capacity is challenging due to varying light conditions and device states.
Innovation Solution
A medical image recording control system that includes a processor to detect device states, determine video source priority based on conditions like room and surgical light states, and a video source switching mechanism to down-convert and record video signals accordingly, ensuring high-priority sources are recorded at high resolution while reducing storage needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If all video sources are recorded at high resolution, then recording quality is improved, but storage capacity is excessively consumed
Solution Approach 1:
The patent applies local quality by assigning different recording qualities to different video sources based on their priority levels. High-priority video sources (such as surgical camera during actual surgery) are recorded at high resolution, while low-priority video sources (such as room camera) are recorded at lower resolution. This resolves the contradiction by ensuring recording quality is maintained for important sources while reducing storage consumption for less important sources.
Solution Approach 2:
The patent changes the recording parameters (resolution, bitrate) dynamically based on the operational phase and priority level of each video source. During different surgical phases, the system adjusts recording quality parameters to match the importance of each video source, thereby optimizing the balance between recording quality and storage capacity utilization.
2Adaptability or versatility
If manual switching of video sources is performed, then recording flexibility is improved, but operation complexity is increased
Solution Approach 1:
The patent implements self-service by enabling the system to automatically determine priority levels and switch video sources based on detected operational phases and device states. The recording control apparatus autonomously monitors the surgical environment, identifies the current phase, and selects appropriate video sources for recording without requiring manual intervention, thereby maintaining flexibility while reducing operational complexity.
Solution Approach 2:
The system uses feedback from device state detection (light sensor readings, device operation status) to automatically adjust video source selection and recording parameters. The recording control apparatus continuously monitors environmental conditions and device states, uses this feedback to determine the current surgical phase, and accordingly adjusts which video sources are recorded and at what quality level.

AI summary
A medical image recording control apparatus includes a processor, a video source switching instruction circuit, and a video source switching device. The processor detects states of a plurality of devices and determines, from a detection result of the states of the plurality of devices, based on states of two or more devices including at least one of a room light, a surgical light, and a light source apparatus for endoscope included in the plurality of devices, a priority level of at least one video source device among a plurality of video source devices included in the plurality of devices. The video source switching instruction circuit generates a switching instruction signal corresponding to the determined priority level. The video source switching device receives the switching instruction signal, switches a video signal outputted to a video signal corresponding to the switching instruction signal, and outputs the video signal.
