Surgical Imaging Device Scan Order Inversion for Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In endoscopic surgery, the existing image inversion function in display devices leads to latency due to the need for storing one image in memory before displaying, causing a delay in transmission time for each screen.
Innovation Solution
A surgical system that includes a surgical imaging device, a signal processing device, and a display device, where the imaging device generates images based on scan information indicating the scan order, allowing the signal processing and display to be performed without waiting for memory storage completion, by specifying the top and bottom direction of the image to be displayed through user interfaces and generating scan information accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image inversion is performed in the display device by storing one image in memory, then the image can be inverted and displayed, but latency occurs due to waiting for storage completion
Solution Approach 1:
The patent applies preliminary action by having the imaging device generate images in reverse scan order (bottom-to-top) before transmission. This pre-adjustment of the scan order eliminates the need for memory storage and inversion processing in the display device, thereby reducing latency while maintaining the image inversion function
2Ease of manufacture
If image transmission is performed serially by raster scan, then the image can be transmitted, but time is lost due to sequential processing
Solution Approach 1:
The patent applies inversion by transmitting the image signal in reverse scan order (bottom-to-top instead of top-to-bottom). This inverted transmission approach allows the display device to display images in the correct orientation without requiring memory storage and inversion processing, thereby reducing transmission time and latency

AI summary
The present technology relates to a surgical system and a surgical imaging device enabled to reduce latency. The surgical imaging device generates a surgical image by imaging the inside of a living body, a signal processing device performs predetermined signal processing on the surgical image, and a display device displays the surgical image on which the signal processing is performed. The imaging device generates the surgical image on the basis of scan information indicating a scan order of the surgical image. The present technology can be applied to, for example, an endoscopic surgical system.
