Video Image Processing for Simultaneous Dual Perspective Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video imaging systems fail to provide high-quality, simultaneous close-up and wide-view perspectives of a target from a single camera source, often requiring costly two-camera setups or manual adjustments that are impractical for multi-tasking scenarios, especially in applications like minimally invasive surgeries where real-time, high-resolution views are critical.
Innovation Solution
A system that processes video images from a single camera source to generate and display two different perspective displays - a detailed and panoramic view - using an image management component with interpolation and frame rate control, allowing for automatic adjustment and high-quality output without the need for multiple cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two cameras are used to capture different perspectives, then image quality and resolution are improved, but system cost and complexity increase
Solution Approach 1:
The patent divides a single video image into multiple regions of interest (ROIs) and processes each region separately to generate different perspective displays. This segmentation allows one camera to function as multiple cameras would, providing different views without requiring multiple physical camera units, thus improving image quality while maintaining system simplicity.
Solution Approach 2:
The patent creates digital copies and transformations of the captured video image to generate multiple perspective displays. By using image processing techniques to create virtual views from a single captured image, the system achieves multi-perspective functionality without the cost and complexity of multiple physical cameras.
2Device complexity
If manual zoom adjustment is used to change perspective, then device complexity is reduced, but ease of operation deteriorates when multi-tasking
Solution Approach 1:
The system automatically identifies regions of interest and generates appropriate perspective displays without requiring manual user intervention. The automatic ROI detection and processing enables the system to adapt to different viewing needs autonomously, eliminating the need for manual zoom adjustments while maintaining operational simplicity, especially important in multi-tasking scenarios where hands-free operation is needed.
3Loss of information
If video image is zoomed to provide close-up perspective, then detail visibility is improved, but image quality deteriorates
Solution Approach 1:
The patent captures the complete scene at full resolution before any processing occurs. By having the entire high-resolution image available in advance, the system can later extract and enlarge specific regions of interest without losing quality, as the source material contains all the detail information needed for high-quality close-up views.
Solution Approach 2:
The patent segments the video image into multiple regions of interest and processes each region independently. This allows the system to focus computational resources on enhancing specific areas, extracting detailed information from those regions while maintaining the ability to provide both close-up and wide-view perspectives from the same original high-resolution capture.
4Productivity
If processing resources are allocated to maintain high frame rate, then real-time performance is improved, but video quality may be compromised
Solution Approach 1:
The patent applies different processing qualities to different regions of the video image. Regions of interest receive enhanced processing and higher quality treatment, while other areas use standard processing. This local differentiation allows the system to maintain high frame rates overall while concentrating computational resources on preserving video quality in the most important areas.

AI summary
Certain embodiments of the present invention include a system and methods for providing a video image display technology with separate video perspective displays. Each perspective display may be tailored and adapted in real-time to the differing roles of each user, e.g., one or more medical professionals of a surgical team. As an example, one video perspective display may be a panoramic perspective display for a primary surgeon and a second video perspective may be a detailed perspective display for the surgical assistant.
