Image Display Program Aspect Ratio Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display methods fail to effectively display images on screens with different aspect ratios without reducing visual quality, as they require pre-preparation of images or specific division patterns, and methods like letterboxing can damage image visibility.
Innovation Solution
An image display program and system that includes an image reader, size determiner, adjuster, and displayer, which adjusts image sizes to fit within a predetermined range relative to the screen size, ensuring similar figures are retained and visual quality is maintained across various aspect ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If letterboxing scheme is used to display image on screens with different aspect ratios, then image aspect ratio matching is improved, but image visibility is worsened
Solution Approach 1:
The patent implements dynamic image size adjustment based on the detected aspect ratio of the display screen. The image processing section continuously adapts the image dimensions to match the screen's aspect ratio, transforming the static letterboxing approach into a dynamic resizing mechanism that maintains image visibility while achieving aspect ratio compatibility across different devices.
2Adaptability or versatility
If image size is adjusted to fit different screen sizes, then adaptability to various displays is improved, but image visual quality is worsened
Solution Approach 1:
The patent changes the size parameter of the image dynamically based on the detected screen dimensions and aspect ratio. By adjusting only the dimensional parameters while preserving the image content and aspect ratio relationships, the system achieves display compatibility without degrading visual quality, allowing the same image to be optimally displayed across various screen sizes.
3Manufacturing precision
If multiple images are prepared for different display types, then display accuracy is improved, but device complexity is worsened
Solution Approach 1:
The patent performs preliminary detection of the display screen's aspect ratio before image display. By detecting the screen characteristics in advance and pre-calculating the appropriate image size adjustments, the system eliminates the need to prepare multiple versioned images for different devices, reducing complexity while maintaining display accuracy through automated adaptation.
Solution Approach 2:
The patent creates a universal image processing system that can handle images for any display type through automated aspect ratio detection and adjustment. Instead of requiring separate image preparation processes for different devices, the single processing pipeline adapts to various screen configurations, making the system multi-functional and reducing overall complexity.

AI summary
An image display program executed in an image display apparatus includes a display section that displays an image, and the program causes the image display apparatus to function as: an image size determiner that determines whether an image size satisfies a predetermined condition; an image size adjuster that adjusts the image size, when it is determined by the image size determiner that the image size does not satisfy the predetermined condition, in a state where the ratio of vertical length and horizontal length of the image is maintained; and an image displayer that displays the adjusted image by the image size adjuster in the display section, when the image size does not satisfy the predetermined condition, and displays an image stored by an image size storage in the display section, when the image size satisfies the predetermined condition.
