Multi-Projector Display Controller Overlap Region Position Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-projection systems face challenges in maintaining image quality in overlap regions, particularly when the position of displayed images changes, leading to blurring and displacement issues.
Innovation Solution
An information processing apparatus with a display controller that prioritizes projection from the projector corresponding to the non-overlap region before moving into the overlap region, and performs position correction when the input position moves within the overlap region, ensuring seamless image display across multiple screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If images are projected from multiple projectors onto overlapping display regions, then the coverage area is expanded, but blurring occurs in the overlap region
Solution Approach 1:
The patent applies different processing strategies to different regions: in non-overlap regions, normal projection is used, while in overlap regions, the system selectively uses input positions from non-overlap regions to determine display positions, thereby maintaining high image quality while preserving expanded coverage
2Ease of operation
If the position of displayed images is changed to follow input position movements, then the interactivity is improved, but displacement and blurring occur in overlap regions
Solution Approach 1:
The patent introduces an intermediary processing step where the system determines whether the input position is in a non-overlap region, and uses this information to mediate the mapping between input position and display position. When input is in a non-overlap region, the corresponding overlap region display position is determined based on this input, preventing direct mapping that would cause displacement
3Manufacturing precision
If geometric correction function weight is increased for overlap regions, then geometric consistency is enhanced, but the system cannot adapt when input position moves between regions
Solution Approach 1:
The patent implements dynamic adaptation by continuously monitoring the input position and determining whether it lies in a non-overlap region. Based on this dynamic assessment, the system adjusts the display position determination strategy: using input positions from non-overlap regions to control display in overlap regions, thereby adapting to position changes while maintaining geometric consistency

AI summary
It is desirable to provide a technology for enhancing quality of a displayed image in an overlap region among a plurality of display regions even in a case where a position of the displayed image is changed. There is provided an information processing apparatus including a display controller (134) that controls display of a displayed image in at least one display region of a plurality of display regions on the basis of an input position detected on the basis of a captured image, in which the plurality of display regions includes a first display region and a second display region, and in a case where the input position has moved to an overlap region where the first display region and the second display region overlap with each other, the display controller controls display of the displayed image in the overlap region on the basis of the input position before moving to the overlap region.
