Solution Overview
Problem
Existing image processing techniques for transforming images are complex and specialized, making it difficult to implement various transformation manners efficiently, particularly when dealing with face shapes.
Innovation Solution
An image processing apparatus that sets a transforming area, divides it into small areas using dividing points, and moves these points to transform the image, allowing for easy and efficient implementation of various transformation types, such as making a face appear sharper or enlarging eyes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an image is enlarged or reduced in a magnification set every small area using related-art techniques, then the face shape can be transformed, but the processing becomes complicated and difficult to adapt to various transforming manners
Solution Approach 1:
The patent changes the control parameter from magnification rate to position of dividing points. By moving dividing points to desired positions, various transforming manners (enlargement, reduction, shape correction) can be achieved through simple parameter adjustment without complex processing for each transformation type
Solution Approach 2:
The patent creates a universal image processing method that can handle multiple transforming manners (face enlargement, reduction, shape correction, etc.) through a single approach of moving dividing points, eliminating the need for specialized processing for each transformation type
2Manufacturing precision
If the transforming area is divided into many small areas, then the transformation precision can be improved, but the processing time and computational load increase
Solution Approach 1:
The patent applies transformation only to necessary small areas within the transforming area rather than processing the entire image, and uses a predetermined number of dividing points that balances precision with processing efficiency, avoiding excessive division
3Ease of operation
If dividing points are moved to transform small areas, then various image transformations can be achieved easily, but maintaining symmetry and avoiding transformation of critical areas like eyes becomes challenging
Solution Approach 1:
The patent intentionally allows asymmetric movement of dividing points on left and right sides to achieve desired face shapes, while using symmetry evaluation to guide the transformation and prevent excessive asymmetry that would look unnatural
Solution Approach 2:
The patent uses symmetry evaluation as feedback to monitor and control the transformation process, ensuring that dividing points are moved appropriately to maintain natural face symmetry while achieving the desired transformation effect
