Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing methods face issues with noticeable adverse effects during skin beautification when the face in an image is small, and the strength of applied effects can be inconsistent due to varying object sizes and angles of view, leading to increased calculation complexity.
Innovation Solution
An image processing apparatus that acquires optical characteristic data and zoom magnification information, calculates the change amount of these factors, and adjusts the applied characteristic to the image data based on this information to generate optimized second image data, reducing blur and ensuring consistent effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image processing such as skin beautification is performed based on face detection, then skin beautification effect is achieved, but adverse effects and image blur become noticeable when the face is small
Solution Approach 1:
The patent changes the parameter for determining image processing based on the object size in the angle of view. Instead of using fixed face detection thresholds, the system dynamically adjusts processing parameters according to the calculated object size, thereby maintaining appropriate processing strength across different imaging conditions and avoiding excessive adverse effects when the face appears small.
2Reliability
If image processing is applied to maintain consistent effects across varying object sizes, then processing consistency is improved, but calculation amount increases
Solution Approach 1:
The patent performs preliminary calculation of the object size in the angle of view based on zoom magnification and distance information before determining the processing characteristics. This preliminary action allows the system to pre-determine appropriate processing parameters, reducing the need for complex real-time calculations and maintaining processing consistency without excessive computational burden.
3Adaptability or versatility
If object size in angle of view is calculated to apply proper characteristics, then processing adaptability is improved, but calculation amount increases
Solution Approach 1:
The patent introduces zoom magnification and distance information as intermediary parameters to indirectly determine the object size in the angle of view. Instead of directly calculating complex geometric parameters, the system uses these intermediary values from the imaging system to derive the effective object size, thereby achieving processing adaptability with reduced calculation complexity.
