Multi-Screen Gaming Display Parallax Artifact Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gaming systems with multiple display screens face issues with parallax artifacts, which distort the perception of three-dimensional images due to the predetermined distance between screens, causing parts of the image to appear on different lines of sight, leading to a non-cohesive and distorted view for the player.
Innovation Solution
The gaming system determines specific locations on each display screen to display image portions such that the appearance of parallax artifacts is reduced or eliminated by adjusting the distances from reference planes based on the player's viewpoint and the distance between screens, ensuring that corresponding image parts fall on the same line of sight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple display screens are used to generate three-dimensional images with actual depth, then the depth perception is improved, but parallax artifacts appear causing distorted perception
Solution Approach 1:
The patent applies local quality by displaying different portions of the three-dimensional image on different display screens at different distances from the player. Specifically, closer portions are displayed on screens closer to the player while farther portions are displayed on screens farther away, creating local variations in display depth that match the perceived three-dimensional structure and eliminate parallax artifacts.
Solution Approach 2:
The patent adds a spatial dimension by positioning multiple display screens at different distances from the player along the depth axis. This transforms a two-dimensional display problem into a three-dimensional display solution, where each screen operates at a different depth plane to render appropriate image portions, thereby eliminating the parallax distortion inherent in single-plane displays.
2Volume of moving object
If display screens are positioned at different distances to create three-dimensional depth, then actual depth is achieved, but image portions appear on different lines of sight causing non-cohesive view
Solution Approach 1:
The patent assigns different display depths to different spatial regions of the three-dimensional image based on their actual depth. Closer objects are rendered on closer screens while farther objects are rendered on farther screens, creating local depth variations that maintain image cohesiveness and prevent parallax artifacts by ensuring all image portions lie on consistent lines of sight from the player's viewpoint.
Solution Approach 2:
The patent segments the three-dimensional image into different depth-based portions and assigns each portion to appropriate display screens based on its depth. This segmentation allows the system to manage the complexity of multi-screen display by treating different depth regions independently, ensuring each region is displayed at the correct depth plane to maintain overall image cohesiveness.

AI summary
Various embodiments of the present disclosure provide gaming systems having reduced appearance of parallax artifacts on display devices including multiple display screens. In one embodiment, the gaming system determines a location on a first display screen of a display device at which to display a portion of a first image and subsequently determines, based on that determined location and one or more other variables, a location on a second display screen of the display device at which to display a portion of a second image such that the appearance of parallax artifacts associated with the first image and the second image is reduced or eliminated.
