Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing methods cannot convert 2D images into 3D effects on mobile terminals due to complexity and the need for specialized technical knowledge, and they require extensive calculations, making them unsuitable for ordinary users and impractical for mobile devices.
Innovation Solution
An image processing method and apparatus that detects the orientation of a mobile terminal and adjusts a background frame on a 2D image to create a 3D effect by moving areas into or out of the frame, allowing users to change the 3D display effects by altering the device's orientation without calculating a perspective matrix, ensuring stability and reliability through set constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex algorithms and large calculations are used to create 3D effects, then the 3D effect can be achieved, but the device complexity and computational requirements increase, making it unsuitable for mobile terminals
Solution Approach 1:
The patent extracts the essential 3D effect creation mechanism from complex perspective matrix calculations and identifies it as a simple background frame adjustment process. By taking out only the necessary frame adjustment functionality, the solution achieves 3D effects without requiring complex algorithms, thus resolving the contradiction between 3D effect quality and device complexity
Solution Approach 2:
The patent uses a simplified copying approach where instead of calculating complex perspective transformations, it creates a background frame that visually replicates the 3D effect by adjusting frame shape and position. This copying method achieves the same visual result with minimal computational complexity, suitable for mobile devices
2Reliability
If specialized technical operations such as matting, drawing and perspective matrix calculation are used, then the 3D effect can be created, but the ease of operation decreases as it requires specialized technical level
Solution Approach 1:
The patent implements self-service by automatically detecting mobile terminal orientation using the sensor system and adjusting the background frame accordingly. Users simply need to hold the device at different angles, and the system automatically creates the 3D effect without requiring users to perform complex manual operations like matting or perspective matrix calculation, thus greatly improving ease of operation
Solution Approach 2:
The patent replaces the mechanical manual operation system (requiring users to manually perform matting, drawing, and calculation) with an automated sensor-based system. The sensor detects orientation and the system automatically adjusts the background frame, substituting complex manual mechanical operations with automatic electronic detection and adjustment, making the process accessible to ordinary users
3Reliability
If complex algorithms are used for 3D effect creation, then the 3D effect can be achieved, but the processing speed and computational efficiency decrease
Solution Approach 1:
The patent extracts the essential 3D effect creation mechanism from complex perspective matrix calculations and identifies it as a simple background frame adjustment process. By taking out only the necessary frame adjustment functionality, the solution achieves 3D effects without requiring complex algorithms, thus resolving the contradiction between 3D effect quality and device complexity
Solution Approach 2:
The patent changes the key parameters from complex perspective matrix calculations to simple geometric frame adjustments. Instead of computing complex transformation matrices, the system adjusts the background frame's shape, position, and orientation parameters directly based on sensor input, dramatically improving processing speed while maintaining 3D effect quality

AI summary
An image processing method and apparatus belong to the technical field of image processing. The method is applied to a mobile terminal, and includes: acquiring a target image on a Two-dimensional (2D) image (S11); creating a Three-Dimensional (3D) image layer, taking the 2D image as a background of the 3D image layer, and creating a background frame on the 3D image layer (S12); detecting an orientation of the mobile terminal, and adjusting a shape of the background frame according to the orientation of the mobile terminal, so that different areas of the 2D image are moved into or out of the background frame (S13); and when the target object on the 2D image is not completely accommodated within the background frame, drawing the target object at a position of the target object on the 3D image layer (S14), where the 2D image, the background frame, and the drawn target object on the 3D image layer are sequentially stacked from bottom to top. The method and the apparatus implement the effect that the 2D image is presented as a 3D effect on the mobile terminal.
