Image Display Method for Consistent Enlargement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display technologies, such as those described in JP-A-2013-231973, fail to ensure that enlarged images displayed on mobile terminals are always larger than their original counterparts, especially when the original images are of different sizes, leading to inconsistent display sizes and user experience issues.
Innovation Solution
An image display method and apparatus that acquires and reduces rectangular images of different sizes, displays thumbnail images in a first area, and upon selection, calculates and stores display coordinates and enlargement ratios to display intermediate images in a second area based on predefined positions, allowing for seamless enlargement and movement of images while maintaining consistent display sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the original image is first reduced to display data and then enlarged, then the image can be displayed on the screen, but the displayed enlarged image is not always larger than the original image
Solution Approach 1:
The patent applies preliminary action by calculating and storing the enlargement ratio and display coordinates before the actual enlargement operation. When a thumbnail is selected, the system retrieves pre-calculated enlargement parameters (enlargement ratio based on original image dimensions and display area, and display coordinates for the prescribed position) to ensure the enlarged image is always larger than the original and positioned correctly, avoiding the need to reduce then enlarge the image.
2Adaptability or versatility
If images of different sizes are displayed, then the system can handle various image formats, but the display coordinates and enlargement ratios vary making consistent display difficult
Solution Approach 1:
The patent applies parameter changes by dynamically calculating enlargement ratios and display coordinates based on the original image's dimensions and the prescribed display position. For each image, the system determines specific parameters (enlargement ratio = display area / original image area, display coordinates = prescribed position adjusted for image size) to ensure that despite varying image sizes, all enlarged images maintain consistent positioning and are always larger than their originals.

AI summary
A method includes displaying, in a first display area, a first display image obtained by reducing a first image, and a second display image obtained by reducing a second image, which has a size different from the first image, displaying, when the first display image is selected, a first intermediate image based on the first image in a second display area, calculating and storing, when the first intermediate image is commanded to be enlarged and moved, the display coordinates of the first intermediate image with respect to an enlargement ratio and a prescribed position, and displaying, when the second display image is selected, a second intermediate image based on the second image and enlarged with respect to a position of the second image, the position corresponding to the prescribed position, in the second display area, according to the stored enlargement ratio and display coordinates.
