Solution Overview

Problem

Electronic devices face challenges in efficiently compressing video files to optimize storage space without compromising display quality, as current compression methods either result in poor image quality or inadequate storage savings.

Innovation Solution

A method and device that acquire and compare the resolution of an image to be compressed with the display screen's resolution, compressing the image to a target resolution within a preset range to ensure optimal display quality while conserving storage space, using modules for acquiring, detecting, and compressing image resolutions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If video files are compressed heavily to save storage space, then storage space is reduced, but display quality becomes extremely poor

Engineering Contradiction:

Improvestorage spaceVSAvoiddisplay quality

Core Design Contradiction:

Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent changes the resolution parameter of the video file to match the display screen's resolution. By detecting the screen resolution and adjusting the video resolution accordingly, the system achieves optimal compression that preserves display quality while reducing storage space requirements.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system automatically detects the display screen resolution and performs self-adjustment of the video file resolution without requiring manual user input. The electronic device itself provides the compression service by matching video resolution to screen resolution, eliminating the need for external compression tools.

Inventive Principle:

Principle #25Self-service

2Manufacturing precision

If video files are not compressed enough to maintain display quality, then display quality is preserved, but storage space is not saved

Engineering Contradiction:

Improvedisplay qualityVSAvoidstorage space

Core Design Contradiction:

Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent optimizes the resolution parameter by setting it to match the display screen's resolution exactly. This precise parameter matching ensures that the video file is compressed to the minimum necessary degree, preserving display quality while achieving maximum storage space savings.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces manual judgment and trial-and-error compression with an automated detection and adjustment system. The electronic device automatically detects screen resolution and applies the appropriate compression, substituting mechanical compression processes with intelligent parameter matching.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The present disclosure provides a method and a device for compressing an image, and an electronic device. The method includes: acquiring a resolution of the display screen and a resolution of an image to be compressed; detecting whether the resolution of the image to be compressed is greater than the resolution of the display screen; and when the resolution of the image to be compressed is greater than the resolution of the display screen, compressing the resolution of the image to be compressed to a target resolution according to the resolution of the display screen, a difference between the target resolution and the resolution of the display screen being within a preset resolution range.
