Electronic Book Page Turn Edge Color Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for displaying electronic book pages during a page turning operation often result in poor color matching, leading to an unsatisfactory display effect due to the use of fixed colors for the folded portion of the page.
Innovation Solution
A method and device that acquire the edge color value and page content of the currently displayed image page, using these to draw and display the folded portion, thereby enhancing color matching and harmoniousness with the image page.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed color (e.g., white or preset sheet color) is used for the folded portion during page turning, then the display process is simple, but the page color cannot be matched well, influencing the page display effect
Solution Approach 1:
The patent applies local quality by extracting the edge color from the current page and applying it specifically to the folded portion, rather than using a uniform fixed color for the entire folded area. This makes the color property local to the folded portion, matching the visual characteristics of the actual page fold and improving color matching accuracy while maintaining implementation simplicity.
2Manufacturing precision
If the edge color value is extracted from the current page, then the color matching with the image page is improved, but additional data processing is required
Solution Approach 1:
The patent extracts only the essential edge color information from the current page image, rather than processing the entire page content. This extraction approach obtains the necessary color data for the folded portion with minimal processing, improving color matching accuracy while avoiding excessive data processing complexity.
Solution Approach 2:
The patent uses partial action by extracting color information only from the edge region of the current page rather than analyzing the entire page. This partial processing approach provides sufficient color matching for the folded portion without the computational overhead of full-page analysis, balancing accuracy and processing efficiency.

AI summary
Disclosed are a method and device for displaying page of electronic book, and a terminal device. The method for displaying page of electronic book includes: in response to receiving a page turning operation for a currently displayed image page of the electronic book, acquiring an edge color value and page content of the currently displayed image page; and drawing and displaying a folded portion with the edge color value and the page content, wherein the folded portion is a back portion of the turned currently displayed image page on which the page turning operation is performed.
