Image Transmission Resolution Matching via Server Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When images are transferred from a mobile device with lower resolution to a television, the display effect is poor due to the difference in screen sizes, resulting in unclear images on the larger screen.
Innovation Solution
A method and device that receive an image of low resolution from a source terminal, send a request to a server for the same image in higher resolution, and display the high-resolution image on the larger device, improving the display effect by matching the image resolution to the device's capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the image from mobile phone is directly displayed on television, then the transmission is simple and fast, but the display quality is poor due to resolution mismatch
Solution Approach 1:
The patent introduces a server as an intermediary between the mobile phone and television. The server receives the low-resolution image from the mobile phone, retrieves or generates a high-resolution version, and transmits it to the television. This mediator resolves the resolution mismatch problem while maintaining system simplicity for the end users.
Solution Approach 2:
The system performs preliminary action by pre-processing the image resolution issue before display. The device detects the resolution mismatch, sends a request to the server in advance, and obtains the high-resolution image before displaying it on the television, ensuring quality display without requiring real-time processing.
2Manufacturing precision
If the image resolution is increased to match television screen, then the display effect is improved, but the network bandwidth and processing requirements increase
Solution Approach 1:
The patent uses copying by retrieving an existing high-resolution version of the image from the server rather than transmitting or processing the low-resolution image locally. The server already stores multiple resolution versions, and the system copies the appropriate high-resolution version for display, avoiding unnecessary bandwidth consumption for transmitting multiple resolution versions.
Solution Approach 2:
The system applies local quality by requesting only the specific high-resolution image data needed for the television display from the server, rather than transmitting all possible resolution versions. The device tailors the request to its specific resolution requirements, optimizing network bandwidth usage while achieving the desired display quality.

AI summary
The present disclosure relates to a method and a device for transmitting an image, which improve display effect of the image. The method includes receiving an image with a first resolution from a source terminal; sending a request for obtaining the image to a server according to an identifier of the image; and receiving the image with a second resolution from the server, wherein the second resolution is higher than the first resolution.
