Calligraphy Image Projection With Overlap Color Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image projection technologies in e-learning of calligraphy result in darkening of instructor's correction lines, reducing visibility and reproducibility of correction results, thus hindering the learning effect.
Innovation Solution
An information processing apparatus that acquires images of a first medium with a written character and a second medium with a different colored correction line, corrects color data in overlapping regions, and projects the corrected image to match the character's position, enhancing visibility and reproducibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional image projection is used to project correction lines onto the student's medium, then the correction results can be transmitted, but the brightness or saturation of the instructor's line decreases in the overlapping region causing darkening that reduces visibility
Solution Approach 1:
The patent changes the color parameters (brightness, saturation) of the correction lines dynamically based on whether they overlap with projected content. In overlapping regions, the correction lines are rendered with adjusted color parameters to maintain visibility, while non-overlapping regions use original color parameters. This resolves the contradiction by adapting the visual parameters of correction lines to the local context.
Solution Approach 2:
The patent applies different visual qualities to different regions of the correction lines. Regions that overlap with projected content receive enhanced color saturation and brightness, while non-overlapping regions maintain their original appearance. This local differentiation ensures visibility is maintained where needed without wasting resources on regions where it's already visible.
2Reliability
If conventional image projection is used to project correction lines onto the student's medium, then the correction process can be completed, but the reproducibility of correction results is reduced due to darkening
Solution Approach 1:
The patent adjusts color parameters of correction lines in overlapping regions to compensate for the darkening effect. By increasing brightness and saturation in these regions, the original color information is preserved and made reproducible, resolving the contradiction between maintaining color fidelity and dealing with overlapping projection effects.
3Ease of operation
If conventional image projection is used, then the projection system remains simple, but the learning effect is hindered due to reduced visibility of improvements
Solution Approach 1:
The patent implements automated color parameter adjustment for correction lines based on overlap detection with projected content. This processing enhancement improves the learning effect by ensuring correction lines remain visible, while the automation keeps the system relatively simple. The contradiction is resolved by using algorithmic processing rather than complex hardware modifications.

AI summary
An information processing apparatus acquires a first image of a first medium including a first region in which a character is written. The information processing apparatus projects the first image onto a predetermined position of a second medium. The information processing apparatus acquires a second image of the second medium including a second region in which a line of a different color from the character depicted in the projected first image is drawn. The information processing apparatus corrects color data of an overlapping region in which the first region and the second region overlap in the second image. The information processing apparatus projects the corrected second image onto the first medium so that the position of the character matches.
