Character Image Legibility with Independent Background Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The difference in scaling factors between character images and background images can lead to deviations in positional relationships, reducing the legibility of characters when displayed, whether scaling down or up.
Innovation Solution
An information processing device adjusts either the character image or the background image based on their respective scaling factors, ensuring the character image does not overlap and maintaining optimal legibility by setting a second scaling factor for the character image different from the first scaling factor of the background image, and adjusting their display positions accordingly.

Engineering Contradiction Analysis
1Measurement precision
If different scaling factors are used for character images and background images, then character legibility is improved, but positional relationship deviation occurs
Solution Approach 1:
The image is divided into character image parts and background image parts, which are scaled independently using different scaling factors. This segmentation allows the character portions to be enlarged relative to the background, improving character legibility while maintaining the overall image structure.
Solution Approach 2:
A positional relationship adjusting unit is introduced as an intermediary component that calculates and adjusts the display positions of character images based on the difference between the first scaling factor (for background) and the second scaling factor (for characters). This mediator ensures that character images are positioned correctly on the background image despite the different scaling factors, preventing positional deviation and maintaining manufacturing precision.

If character images are scaled with different factor than background images, then character size is improved, but overlap between character images occurs
Solution Approach 1:
The display positions of character images are dynamically adjusted based on the scaling factor difference. The positional relationship adjusting unit calculates the position shift for each character image and applies corrections in real-time, allowing the character arrangement to adapt to the different scaling factors while preventing overlap and maintaining stable composition.
Solution Approach 2:
The system changes the display position parameters of character images to compensate for the different scaling factors. By adjusting the position coordinates of each character image based on the scaling difference, the system prevents overlap while maintaining the intended character size enhancement.

AI summary
It is an object to improve the legibility of characters shown by a character image part included in a displayed image in which the scaling factor of the character image part is set to be different from the scaling factor of a background image part. An information processing device sets a second scaling factor used to display a character image extracted from an image. The second scaling factor is different from a first scaling factor used to display a background image extracted from the image. The information processing device adjusts at least either the character image changed in display size with the second scaling factor or the background image changed in display size with the first scaling factor, based on the relationship between the display state of the character image changed in display size and the display state of the surrounding area of the character image that has been changed in display size and is overlaid on the background image changed in display size.
