Image Processing Apparatus Skin Beautification Out-of-Focus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing techniques fail to achieve the desired skin beautification effect on a person's face when the face is not in focus, particularly in product review scenarios where review AF is used.
Innovation Solution
An image processing apparatus that includes a processor to input an image, set whether to execute a correction process on a target region, determine if a condition is met, adjust the correction amount based on a threshold, and apply the correction process using the adjusted amount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If skin beautification processing is applied to a person's face in an image, then the skin appears smoother and blemishes are removed, but the resolution of the processed area is reduced
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the correction amount based on the in-focus status of the face. When the face is detected as out-of-focus, the correction amount is reduced to prevent excessive smoothing that would further degrade resolution. This parameter adjustment allows the system to maintain appropriate skin beautification effects while preserving image quality.
2Productivity
If conventional skin beautification techniques are applied when the face is not in focus, then the correction process runs, but the skin beautification effect is not achieved as expected
Solution Approach 1:
The patent implements feedback by detecting the in-focus status of the face and using this information to adjust the correction amount. The determination unit assesses whether the face is in-focus, and based on this feedback, the changing unit adjusts the correction amount accordingly. This feedback mechanism ensures that skin beautification processing is effective only when the face is properly focused.
Solution Approach 2:
The patent applies dynamics by making the correction amount adjustable rather than fixed. The system dynamically changes the correction amount based on real-time detection of the face's in-focus status. When the face is out-of-focus, the correction amount is automatically reduced, allowing the system to adapt to different imaging conditions and maintain reliable skin beautification effects.
3Ease of manufacture
If a large correction amount is applied to out-of-focus faces, then the skin beautification effect is enhanced, but over-smoothing occurs and image quality deteriorates
Solution Approach 1:
The patent applies preliminary anti-action by detecting the out-of-focus status of the face before applying the full correction process. When the face is detected as out-of-focus, the system preemptively reduces the correction amount to prevent over-smoothing and image quality deterioration. This preliminary assessment and adjustment prevents harmful effects before they occur.

AI summary
An image processing apparatus sets whether or not to execute a predetermined correction process on a correction target region in an image input via an input unit, and sets a first correction amount in a case where the correction process is to be executed; determines whether a predetermined condition is satisfied, and, if so, further determines whether the first correction amount is a predetermined threshold or more; changes the first correction amount to a second correction amount smaller than the first correction amount if the first correction amount is the threshold or more; and, if the execution of the correction process is set, executes the correction process on the correction target region of the image based on the second correction amount, or on the first correction amount if the first correction amount is not changed to the second correction amount.
