ROI Image Restoration in Reception Devices for Display Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to efficiently process and display regions of interest (ROIs) cut from captured images, leading to potential system overload and transmission failures.
Innovation Solution
A reception device and transmission system that include a reception unit for receiving ROI image data and information, and a processing unit for restoring and displaying these regions based on embedded data, using standards like MIPI CSI-2 and DSI.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If all captured images are transmitted, then complete image data is available, but the transmission system becomes overloaded and may go down
Solution Approach 1:
The patent extracts only the necessary region of interest (ROI) from the captured image and transmits only that extracted portion rather than the complete image. This extraction principle reduces the quantity of transmitted data while maintaining the essential information needed for the application, thereby preventing transmission system overload.
Solution Approach 2:
The patent segments the captured image into multiple regions and identifies the specific ROI that needs to be transmitted. By dividing the complete image into segments and transmitting only the relevant segment, the system reduces data volume while maintaining transmission reliability.
2Speed
If ROI image data is transmitted without restoration processing, then transmission speed is maintained, but the display device cannot properly display the ROI
Solution Approach 1:
The patent performs restoration processing on the ROI data at the receiving end before display. This preliminary action ensures that the ROI data is properly formatted and restored to its original quality, making it compatible with standard display devices while maintaining fast transmission speeds.
3Loss of energy
If only ROI data is transmitted, then transmission load is reduced, but processing for efficient display of ROIs has not been studied
Solution Approach 1:
The patent implements restoration processing that automatically restores the ROI data to its original state without requiring manual intervention or complex additional processing. This self-service approach maintains high display efficiency while minimizing transmission load.

AI summary
An object is to efficiently display pieces of image data of some regions of interest (ROI) cut from a captured image on a display device. A reception device includes: a reception unit that receives a transmission signal in which image data of a predetermined number of regions of interest (ROIs) cut from a predetermined captured image is included in payload data and ROI information corresponding to a predetermined number of the ROIs is included in embedded data; and a processing unit that is configured to perform restoration processing of restoring the image data of the ROI so as to be displayable on a predetermined display device on the basis of the ROI information extracted from the embedded data.
