Solution Overview

Problem

Existing methods for super-resolution processing of multimedia information cover page images require significant time, leading to poor preview effects when users quickly browse through multimedia content.

Innovation Solution

A method where a client acquires and performs super-resolution processing on multiple cover page images in advance, displaying them only when needed, optimizing image parameters and utilizing parallel processing to enhance efficiency and reduce resource consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If super-resolution processing is performed on cover page images when the client requests them, then the image quality is improved, but the processing time increases and the preview effect deteriorates

Engineering Contradiction:
Improveimage qualityVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing super-resolution processing on cover page images in advance, before the user actually views them. The system pre-processes images for multiple pieces of multimedia information that are likely to be displayed next, so that when the user quickly browses through content, the high-quality images are already ready for immediate display, eliminating the time delay between request and processing

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments the super-resolution processing task by dividing it into multiple processing groups based on image parameters. Different processing models are applied to different groups of images in parallel, allowing the system to handle multiple images simultaneously rather than sequentially, thus reducing overall processing time while maintaining quality

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If super-resolution processing is performed on multiple cover page images simultaneously, then the preview effect is improved, but the resource consumption increases

Engineering Contradiction:
Improvepreview effectVSAvoidresource consumption
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by selectively performing super-resolution processing only on images that are likely to be displayed next, rather than processing all images. The system determines N pieces of second multimedia information based on display interface capacity and user browsing behavior, processing only the necessary subset of images to achieve good preview effect while avoiding unnecessary resource consumption on images that won't be viewed

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent changes processing parameters by dividing images into M processing groups based on image parameters and applying different processing models to different groups. This allows the system to optimize resource allocation by matching processing complexity to image characteristics, reducing overall computational resources needed while maintaining quality across diverse image types

Inventive Principle:
Principle #35Parameter changes

AI summary

A method of processing a cover page image of multimedia information, a client and an electronic device are provided. The method includes: acquiring initial cover page images of N pieces of second multimedia information following first multimedia information, where the first multimedia information is displayed on a current display interface of the client, the N pieces of second multimedia information are not displayed on the current display interface of the client, and N is an integer greater than or equal to 1; performing a super-resolution processing on the initial cover page images of the N pieces of second multimedia information, to obtain super-resolution cover page images of the N pieces of second multimedia information; and displaying the super-resolution cover page images of the second multimedia information, in a case that the second multimedia information enters the current display interface.
