Multi-Screen Image Processing Circuit Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-screen display systems face increased bandwidth requirements and computing resource usage due to overlapping images, which affects image quality and necessitates higher hardware resources, limiting the ability to display images near full screen without increasing bandwidth and storage needs.
Innovation Solution
An image processing device comprising an image processing circuit, transmission arrangement circuit, and image merge circuit processes multiple image sources by generating packets that reduce data volume of overlapping images, allowing them to be transmitted and displayed with reduced bandwidth, maintaining image quality and refresh rate without increasing hardware resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple image screens are received and displayed with partial overlap or reduced display screen, then the display can show multiple images, but the bandwidth requirements and computing resources are significantly increased
Solution Approach 1:
The patent extracts only the visible portions of images that are not blocked by other display screens. The processing circuit identifies blocked regions and excludes them from transmission, sending only the necessary visible image data through the transmission arrangement circuit to the output interface circuit, thereby reducing bandwidth requirements while maintaining multi-screen display capability
Solution Approach 2:
Instead of transmitting complete image data for all multiple images, the system performs partial action by transmitting only the visible portions of each image. This partial transmission approach reduces the total data volume and bandwidth requirements while still achieving the multi-screen display effect
2Adaptability or versatility
If the number of image sources is increased, then more images can be displayed, but the bandwidth requirements and computing resources are increased proportionally
Solution Approach 1:
The processing circuit extracts and identifies blocked regions in each image based on the stacking arrangement, and the transmission arrangement circuit excludes these blocked portions from transmission. This extraction of only necessary visible data allows the system to handle multiple image sources without proportionally increasing bandwidth and hardware resource requirements
Solution Approach 2:
The system changes the parameter of image data transmission by transforming complete image transmission into selective partial image transmission. By modifying the data transmission parameter from full-image to visible-portion-only, the system can accommodate more image sources without linearly increasing hardware complexity
3Adaptability or versatility
If overlapping display screens are used, then multiple images can be shown on the same screen, but the portion of image that is blocked and not displayed still occupies memory and transmission bandwidth
Solution Approach 1:
The processing circuit extracts and identifies blocked regions that will not be displayed due to screen stacking overlap. The transmission arrangement circuit then excludes these extracted blocked portions from the transmission data stream, eliminating wasted bandwidth transmission of invisible image portions while maintaining the multi-screen display effect
Solution Approach 2:
The system discards the blocked image portions that would otherwise be transmitted but not displayed. By discarding these unnecessary data elements at the processing stage, the system recovers transmission bandwidth that would have been wasted, allowing more efficient use of available bandwidth for actual visible content
Data Source
AI summary
An image processing device and method for displaying multi-screen are provided. The image processing device includes an image processing circuit, a transmission arrangement circuit, and an image merge circuit. The image processing circuit receives and processes a first image information with a first bandwidth and a second image information with a second bandwidth to generate a first image information package and a second image information package which are transmitted to the transmission arrangement circuit. The image merge circuit receives and restores the first image information package and the second image information package from the transmission arrangement circuit with a third bandwidth, and outputs the first image information package and the second image information package to a display together. When the first image information and the second image information are in a full-screen mode, the third bandwidth is less than a sum of the first bandwidth and the second bandwidth.
