Image Processing Apparatus Overlapping Modification Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing techniques fail to effectively handle overlapping modification areas, leading to unnatural image modifications due to repeated processing on overlapping portions.
Innovation Solution
An image processing apparatus that detects overlapping areas and reduces the modification level within these areas, allowing for more natural image modification by dividing areas into sub-regions and adjusting the modification level on a sub-area basis, potentially setting it to zero to prevent modification in overlapping portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If modification processes are applied to overlapping areas, then the modification effect is enhanced, but unnatural modification artifacts occur due to repeated processing
Solution Approach 1:
The patent applies different modification levels to different regions within modification areas. Specifically, overlapping regions are assigned a reduced modification level (potentially zero) while non-overlapping regions receive the full intended modification level. This local differentiation resolves the contradiction by preventing unnatural artifacts in overlapping areas while maintaining effective modification in non-overlapping areas.
2Ease of manufacture
If correction areas are predetermined for specific image regions, then the modification process is simplified, but overlapping correction areas cannot be handled
Solution Approach 1:
The patent segments the modification area into multiple sub-areas and establishes individual modification levels for each sub-area. This segmentation enables the system to handle overlapping correction areas by assigning appropriate modification levels to each segment, thereby resolving the contradiction between process simplicity and adaptability to overlapping regions.
3Reliability
If modification level is reduced in overlapping areas, then unnatural modification is prevented, but the overall modification effectiveness is decreased
Solution Approach 1:
The patent applies different modification levels to different regions: full modification level in non-overlapping areas and reduced (or zero) modification level in overlapping areas. This local quality approach resolves the contradiction by maintaining high modification effectiveness in non-overlapping regions while ensuring naturalness in overlapping regions.

AI summary
To improve modification result where areas targeted for modification overlap, an image processing apparatus is provided. The image processing apparatus has a modification area establishing unit capable to establish a plurality of modification areas on a target image by analyzing the target image; an overlap detecting unit that detects overlapping of the plurality of modification areas; and a modification processing unit that modifies an image within a partial area including an overlapping portion of the plurality of modification areas in a reduced modification level in the case that the overlapping is detected by the overlap detecting unit, the reduced modification level being smaller than a modification level used in the case that the overlapping is not detected, the partial area belonging to at least one of the plurality of modification areas.
