Image Preview Selection via Page Evaluation Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing methods fail to effectively display a preview image for data with multiple pages lacking a title or cover sheet, leading to user difficulty in recognizing content, as they either sequentially display all pages or select a representative image based on the last added image, which may not represent the data's typical characteristics.
Innovation Solution
An image processing apparatus and method that calculates an evaluation value for each page based on metadata, such as a 'score of favorite,' to determine a representative page for preview, producing a reduced image of this page for display, allowing users to easily recognize the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all pages are sequentially displayed for previewing, then the user can view all content, but the user has to view multiple preview images and cannot quickly recognize the content
Solution Approach 1:
The patent extracts only the most representative page from the multi-page data structure and displays it as the preview image. This is achieved by evaluating each page based on criteria such as whether it contains a title, images, or other significant content elements, then selecting and displaying only that representative page. This extraction approach eliminates the need to display all pages sequentially while still providing content recognition capability.
2Ease of manufacture
If the last added image is selected as the representative image, then the selection process is simple, but the selected image may not represent the typical characteristics of the data
Solution Approach 1:
The patent implements a feedback mechanism where each page is evaluated based on multiple criteria (presence of titles, images, text content, etc.) and assigned a representativeness score. The system then uses this feedback information to automatically select the page with the highest score as the representative preview image. This ensures that the selected image reliably represents the typical characteristics of the data while maintaining an automated, efficient selection process.
3Device complexity
If the first page is displayed for previewing, then the display process is simple, but the content may not be recognizable if there is no title or cover sheet
Solution Approach 1:
The patent performs preliminary evaluation of all pages before selecting the preview image. The system预先 (in advance) analyzes each page's content characteristics, such as the presence of titles, images, and text, and determines which page would be most representative. This preliminary action ensures that the selected preview image will effectively convey the content information, even though it may not be the first page of the document.

AI summary
In a conventional image processing apparatus configured to display a preview image of a representative page of an image file including a plurality of pages and including a plurality of pieces of image data, it is difficult for a user to easily recognize, from the preview image, the content of the image file stored in a storage medium. In a technique according to the present invention, a page having a high evaluation value is detected, and a reduced image of the detected page is produced. The resultant reduced image is displayed as the preview image thereby allowing a user to easily recognize the content of the file.
