Solution Overview

Problem

Current preview applications on mobile devices struggle to effectively display the target application due to differences in significance between the target application and background icons, leading to a less clear preview effect for users.

Innovation Solution

A method and device for image processing that modify factors such as grayscale, luminance, chrominance, and transparency of the target application and background pictures to enhance the visual prominence of the target application, ensuring its values are higher than or lower than the background, thereby improving the display effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the target application picture is overlaid on a background picture with simulated environment icons, then the preview function is implemented, but the target application picture is not visually prominent and users have difficulty finding it

Engineering Contradiction:
ImproveUser ability to find target applicationVSAvoidVisual prominence of target application
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent applies color and luminance adjustments to the target application picture, making it stand out from the background by modifying its chromaticity and brightness characteristics. This allows users to quickly locate the target application among background icons through visual differentiation.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent modifies multiple picture parameters including luminance, chrominance, and grayscale values of the target application picture. By adjusting these parameters, the target application achieves visual prominence while maintaining the overall preview functionality.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If the significance of background icons is made equal to or higher than the target application picture, then the simulated environment is enhanced, but the preview effect of the target application is degraded

Engineering Contradiction:
ImproveSimulated environment consistencyVSAvoidPreview clarity of target application
Core Design Contradiction:
Stability of the object's compositionVSLoss of information

Solution Approach 1:

The patent applies different visual processing to different regions of the composite image. The target application picture receives enhanced processing (luminance, chrominance adjustments) while background icons maintain their original appearance, creating local quality differences that guide user attention to the target application.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

By selectively modifying the color properties of the target application picture while leaving background icons unchanged, the patent creates visual hierarchy that preserves environment consistency while ensuring target application prominence.

Inventive Principle:
Principle #32Color changes

3Device complexity

If no image processing is applied to distinguish the target application, then the processing complexity is low, but the display effect and user experience are degraded

Engineering Contradiction:
ImproveImage processing complexityVSAvoidPreview display quality
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent implements relatively simple parameter adjustments (luminance, chrominance, grayscale) on the target application picture rather than complex processing algorithms. This approach achieves good preview quality with controlled processing complexity, balancing performance and visual effect.

Inventive Principle:
Principle #35Parameter changes

AI summary

An image processing method and an apparatus are disclosed and are used for improving the display effect of the image. The method involves: determining an object application picture and the real environment of the object application according to triggering of a preview event; acquiring a background picture according to the real environment of the object application; processing at least one of the object application picture and the background picture, so that the object application picture is more significant than the background picture; outputting the combination of the object application picture and the background picture in the preview environment. An apparatus for implementing the method is disclosed.
