Printed-Image Content Provision with Adaptive Reference Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in accurately displaying augmented reality content on a display screen due to variations in the size of the medium on which printed images are rendered, leading to misalignment of the content with the marker on the printed matter.
Innovation Solution
A content provision system that includes a processor to set a target image and associate it with display content, transmit printing data to a designated medium, read the printed image, specify the storage destination from a corresponding portion, and transmit display data to align the content accurately on the display screen based on the printed image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the content is displayed at a position decided with a marker of the printed matter as a reference, then the content can be displayed on the display screen, but the content may not be appropriately displayed when the size of the medium is not appropriate
Solution Approach 1:
The patent changes the reference parameter from a fixed marker position to a flexible reference point based on the largest continuous black area in the printed image. This allows the system to adapt to different medium sizes by dynamically determining the reference position rather than relying on a predetermined marker location, thereby resolving the contradiction between display capability and position accuracy.
2Device complexity
If a marker is used as a reference for content display, then content positioning is simplified, but the relative position between the printed matter and marker may change depending on medium size
Solution Approach 1:
The system performs self-positioning by automatically detecting the largest continuous black area in the printed image and using it as the reference point. This eliminates the need for external markers while maintaining reliable positioning, as the reference is derived from the printed content itself rather than requiring separate marker elements.
3Adaptability or versatility
If the system supports different medium sizes, then versatility is improved, but the content may not be appropriately displayed due to position changes
Solution Approach 1:
The patent creates a universal positioning method that works across different medium sizes by using the largest continuous black area as a size-independent reference point. This approach makes the system multi-functional, capable of handling various medium dimensions while maintaining consistent content positioning accuracy through the standardized reference determination process.
