Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying images from multiple cameras in online conferences are limited by position and distance, leading to unclear images or the need to switch screens, making it difficult to simultaneously and efficiently process images from various sources.
Innovation Solution
An input and output device with a USB host control unit and image processing unit that receives images from cameras, merges them into a single image, and transmits this merged image to a computing device, supporting multiple formats like HDMI, LVDS, and DP, and optionally using wireless connectivity for seamless display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If general display methods are used to show images from multiple cameras, then the system is simple to operate, but the images become unclear or require screen switching
Solution Approach 1:
The patent merges multiple camera images into a single composite image by integrating multiple image sources into one unified display output. The image processing unit combines images from multiple cameras, allowing simultaneous display of multiple video feeds without requiring users to switch between separate screens, thereby maintaining image clarity while managing display complexity.
Solution Approach 2:
The patent introduces an image processing unit as an intermediary component between the multiple cameras and the display device. This intermediary unit processes, merges, and composite the images from multiple cameras before outputting the final merged image, enabling clear simultaneous display without directly complicating the overall system architecture.
2Ease of operation
If multiple screens are used to display images from different cameras, then each image can be displayed clearly, but the operation becomes complex and requires screen switching
Solution Approach 1:
The patent combines multiple camera images into a single merged image that can be displayed on one screen simultaneously. By merging the images in the image processing unit and outputting a unified composite image, the system eliminates the need for users to switch between multiple screens, thereby simplifying operation and reducing the time lost to screen switching while maintaining all images in view.
3Productivity
If images from multiple cameras are processed separately, then each image maintains its quality, but the processing efficiency decreases
Solution Approach 1:
The patent merges the processing of multiple camera images into a unified processing pipeline within the image processing unit. Instead of processing each image separately through independent channels, the system integrates the images and processes them together to create a merged output, thereby improving processing efficiency while maintaining image quality through coordinated processing.
