Multi-Display Image Positioning Based on Size Ratios
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display methods for multi-projection systems do not efficiently adjust image content within a display region, leading to suboptimal user convenience due to assumptions about image content alignment and size ratios.
Innovation Solution
A method where display devices adjust the position of an image within a rectangular display region based on size ratios, arranging the image such that it contacts specific sides of the region, allowing for optimal alignment and aspect ratio maintenance, and providing mode settings for user-preferred positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image is displayed without considering size ratios and alignment preferences, then the display process is simple, but user convenience deteriorates due to suboptimal image positioning
Solution Approach 1:
The system performs preliminary analysis of the display region size and aspect ratio before displaying the image, calculating the optimal positioning in advance. This preliminary action determines whether to display the image at a first position (when half the display width is less than or equal to the image width) or at a second position (when half the display width is greater than the image width), thereby improving user convenience without requiring complex real-time adjustments.
2Adaptability or versatility
If the image is always displayed at the center position, then the display method is simple, but adaptability deteriorates because it does not account for different size ratios and user preferences
Solution Approach 1:
The system dynamically adjusts the image position based on the relationship between the display region dimensions and the image dimensions. When the half width of the display region is less than or equal to the image width, the image is positioned at the first position; otherwise, it is positioned at the second position. This dynamic positioning strategy enhances adaptability to different display scenarios while maintaining manageable complexity through clear conditional logic.
3Manufacturing precision
If the image size is not adjusted according to display region size, then the processing is simpler, but manufacturing precision deteriorates as the image may protrude or be improperly sized
Solution Approach 1:
The system changes the positioning parameters (first position or second position) based on the relationship between the display region size and the image size. By comparing the half width of the display region with the image width, the system selects the appropriate position to ensure the image is properly contained and precisely positioned without protruding, thereby achieving high positioning precision with relatively simple parameter-based control.

AI summary
A display method includes acquiring a rectangular first image and, when a half value of a first size indicating a size on a first axis of a rectangular display region where an image is displayed by one or more display devices is equal to or smaller than a second size indicating a size on the first axis of the first image, the one or more display devices displaying, in the display region, a first display image including the first image arranged in a first position, where a first side orthogonal to the first axis and located on one side of the first axis among four sides of the display region and a third side orthogonal to the first axis and located on the one side among four sides of the first image are in contact, or a second position where a second side opposed to the first side among the four sides of the display region and a fourth side opposed to the third side among the four sides of the first image are in contact.
