Image Display Apparatus Resizing and Scrolling for Aspect Ratio Mismatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display technologies fail to effectively display images with aspect ratios different from the display area, leading to poor viewability and the need for scrolling, which may not be desirable in all cases, especially when the aspect ratios of the original and display areas do not match.
Innovation Solution
An image display apparatus and method that calculates and applies separate magnifications for resizing images in both horizontal and vertical directions to fit the display area, with optional scrolling to ensure the entire image is viewable, and a determination unit to decide on scrolling based on the display's operation state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the original image is resized to match the display area aspect ratio, then the display image can be shown in the entire display area, but the entire original image cannot be displayed and viewability deteriorates
Solution Approach 1:
The patent segments the original image into multiple displayable portions by implementing scrolling functionality. When the aspect ratios don't match, the image is divided into sections that can be displayed sequentially, allowing the entire original image to be viewed across multiple frames or screens without losing any information.
Solution Approach 2:
The patent introduces dynamic scrolling control that allows the display to adapt between different modes: when aspect ratios match, the entire image is displayed at once; when they don't match, scrolling is enabled to display the complete image. This dynamic adjustment resolves the contradiction by making the display behavior flexible based on the specific situation.
2Loss of information
If scrolling is implemented to display the entire original image, then image completeness is improved, but device complexity and operation complexity increase
Solution Approach 1:
The patent performs preliminary assessment of aspect ratio compatibility before initiating display. By calculating and comparing aspect ratios in advance, the system determines whether scrolling is needed, avoiding unnecessary scrolling mechanisms when the image already fits the display area, thus reducing complexity.
Solution Approach 2:
The display system automatically detects aspect ratio mismatches and activates scrolling independently without requiring user intervention. The system self-manages the complexity of determining when and how to scroll, making the process transparent to the user while maintaining image completeness.
3Manufacturing precision
If separate magnifications are calculated for horizontal and vertical directions, then image resizing precision is improved, but calculation complexity increases
Solution Approach 1:
The patent applies different magnification factors to different dimensions (horizontal and vertical) based on their specific requirements. Instead of using a uniform scaling approach, the system calculates separate magnifications for each direction, allowing precise control over how the image is resized to match the display area while maintaining aspect ratio relationships.

AI summary
The system control section 50 displays the entire original image as a display image, or scrolls a display image with a part of the original image being the display image, depending on relationship between the aspect ratios of the original image and the display area.
