Image Color Conversion Edge Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the color conversion process, information is lost when pixels corresponding to a designated color are converted into a specific color, especially when the designated color is similar to the color of objects within the image, causing boundaries to be indistinguishable and leading to the loss of expressed information.
Innovation Solution
An information processing apparatus that includes a recognition unit to identify objects in an image using a single color and a conversion unit that converts pixels at the outer edge of objects in contact with the designated color into a color other than the specific color, if the color difference is smaller than a reference threshold, to maintain information integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conversion is performed on pixels corresponding to a designated color into a specific color, then the color conversion efficiency is improved, but information loss occurs when objects expressed using the specific color inside the designated color area become indistinguishable
Solution Approach 1:
The patent segments the color conversion process into two distinct stages: first converting pixels of the designated color to the specific color, then identifying and protecting objects expressed using that specific color by preventing their conversion. This segmentation allows the system to maintain high conversion efficiency for the majority of pixels while preserving information for specific objects within the converted area.
Solution Approach 2:
The patent performs object recognition and identification before completing the color conversion process. By preliminarily identifying objects that are expressed using the specific color and determining their outer edges, the system can prepare protection measures in advance, ensuring that these objects remain distinguishable after the color conversion is applied to the surrounding pixels.
2Stability of the object's composition
If conversion is performed on all pixels of the designated color, then the color uniformity is improved, but the boundaries of objects inside the designated color area become indistinguishable
Solution Approach 1:
The patent applies local quality by treating different regions within the designated color area differently. Pixels that are part of objects expressed using the specific color are excluded from conversion, while other pixels of the designated color are converted to the specific color. This creates a localized distinction that maintains color uniformity in the converted areas while preserving boundary distinguishability for protected objects.

AI summary
An information processing apparatus includes a recognition unit that recognizes an object which is included in an image and is expressed using a single color, and a conversion unit that performs conversion on a pixel, which is included in the image and corresponds to a designated color, into a specific color, and, in a case where a color of an area, which is in contact with an outer edge of the recognized object, is designated and a difference between the color of the recognized object and the specific color is smaller than a first reference, performs conversion on a pixel of the outer edge into a color other than the specific color.
