Image Display Control Apparatus for Aspect Ratio Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display technologies face challenges in efficiently displaying multiple images of varying sizes and aspect ratios in a list format without reducing their visibility, often requiring time-consuming operations to enlarge or reduce images to fit a uniform display area.
Innovation Solution
An image display control apparatus that divides a rectangular display area into sub-areas aligned with one side's length, ensuring each image is enlarged or reduced to match this length while maintaining its aspect ratio, thereby preventing visibility reduction when displayed side by side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If images are displayed in a uniform matrix of sub-areas with same size and aspect ratio, then images can be displayed in an organized list format, but images may be reduced in size and become less visible
Solution Approach 1:
The display area is divided into multiple sub-areas arranged in a matrix, with each sub-area dedicated to displaying one image. This segmentation allows multiple images to be organized in a list format while maintaining their individual display characteristics, resolving the contradiction between organized display and image visibility.
2Area of moving object
If images are enlarged to improve visibility, then image detail becomes more visible, but time-consuming operations are required for enlargement
Solution Approach 1:
The system pre-calculates and stores the optimal display size for each image based on its aspect ratio and the available sub-area dimensions. When display is requested, the pre-computed enlargement/reduction ratios are applied immediately without requiring time-consuming user operations, thus improving visibility while minimizing time loss.
3Quantity of substance
If images are reduced to fit uniform sub-areas, then all images can be displayed in the list, but aspect ratios may be distorted and visibility reduced
Solution Approach 1:
Each sub-area is configured with dimensions that match the aspect ratio of its corresponding image, allowing each image to be displayed with its original aspect ratio preserved. This local adaptation of sub-area dimensions to individual image characteristics enables both multiple images to be displayed and aspect ratios to be maintained accurately.

AI summary
An image display control apparatus includes a division unit and a display controller. The division unit divides a rectangular display area into plural rectangular sub-areas in a direction in which one side of the display area extends. The display controller performs display control to enlarge or reduce rectangular images so that while aspect ratios of the images are maintained, a length of each of the sub-areas in the direction in which the one side of the display area extends is equal to or substantially equal to a length of each of the images in the direction in which the one side of the display area extends, and to display at least some of the enlarged or reduced images in the sub-areas.
