Image Deformation Using Subject Size and Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies fail to effectively reduce the difference between the impression of a digital image and the actual object, particularly for specific subjects like faces, due to variations in size and perspective, leading to suboptimal deformation results.
Innovation Solution
An image processing device that sets the size of a specific subject in both width and depth directions within a target image and deforms the image area corresponding to these sizes, using a deformation processing unit to adjust the image deformation degree based on the set sizes and detected subject distance, thereby reducing the impression gap between the digital and real object impressions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the image is deformed using a fixed correction pattern, then the deformation process is simple, but the impression difference between digital image and real object cannot be effectively reduced
Solution Approach 1:
The patent applies dynamics by making the deformation pattern adjustable rather than fixed. The deformation amount in the depth direction can be dynamically changed based on the subject's actual size and distance, allowing the system to adapt to different imaging conditions and reduce impression differences effectively.
Solution Approach 2:
The patent changes the deformation parameters based on detected subject characteristics. By adjusting the deformation amount in the depth direction according to the subject's size and distance from the imaging apparatus, the system achieves more accurate impression matching while maintaining operational simplicity.
2Manufacturing precision
If the deformation degree is increased to reduce impression difference, then the impression accuracy improves, but the image may become overly distorted
Solution Approach 1:
The patent implements feedback by detecting the subject's size and distance from the imaging apparatus, then using this information to calculate an appropriate deformation amount. This feedback mechanism ensures that the deformation is just enough to correct impression differences without over-distorting the image, maintaining naturalness.
Solution Approach 2:
The system dynamically adjusts the deformation parameter based on detected subject characteristics. By calculating the deformation amount as a function of subject size and distance, the system achieves the minimum necessary deformation to correct impressions while avoiding excessive distortion that would compromise image naturalness.
3Device complexity
If the image processing considers only width direction size, then the processing is simpler, but the impression difference due to depth direction size cannot be corrected
Solution Approach 1:
The patent extends the deformation correction from the traditional two-dimensional width direction to include the three-dimensional depth direction. By introducing depth direction deformation based on detected subject size and distance, the system comprehensively addresses impression differences while maintaining manageable processing complexity through targeted deformation zones.

AI summary
An image processing device includes a size setting unit and a deformation processing unit. The size setting unit sets the size of a specific subject in the width direction and in the depth direction in a target image generated through imaging. The deformation processing unit deforms an image within an area, which includes an image of the specific subject in the target image, to a deformation degree corresponding to the set size.
