Projector Arrangement Estimation for Multi-Device Display Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems require users to manually set which part of an image each display device should show, leading to low user-friendliness when multiple devices are used to display a single image.
Innovation Solution
A display device with an image input unit, a display unit, an estimation unit, and a display control unit that estimates and displays the arrangement of multiple display devices based on image resolution, allowing users to adjust the arrangement and set display areas through an intuitive interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually set display areas for each display device, then precise control over image distribution is achieved, but user-friendliness deteriorates due to complex operations
Solution Approach 1:
The system performs automatic arrangement estimation and display area setting without requiring user intervention. The estimation unit automatically determines the arrangement of display devices based on resolution information, and the control unit automatically sets display areas according to the estimated arrangement, enabling the system to serve itself rather than requiring manual user configuration
Solution Approach 2:
The system performs preliminary estimation of display device arrangement before actual image display. By预先 determining the arrangement based on resolution information and pre-setting display areas, the system prepares the configuration in advance, eliminating the need for users to perform complex manual settings during operation
2Ease of operation
If automatic arrangement estimation is implemented, then user-friendliness improves by reducing manual settings, but measurement precision may deteriorate without accurate user input
Solution Approach 1:
The system uses resolution information as feedback to estimate the arrangement of display devices. By analyzing the resolution characteristics of the input image and the display capabilities of connected devices, the estimation unit can infer the likely arrangement configuration, creating a feedback loop that improves automatic arrangement determination
Solution Approach 2:
The system changes the parameter basis for arrangement determination from manual user input to automatic resolution-based estimation. By utilizing resolution parameters of images and display devices, the system transforms the arrangement estimation process into an automated parameter-matching operation that maintains sufficient accuracy without requiring precise user input
3Area of stationary object
If multiple display devices are used to display a single image, then display coverage increases, but setup complexity increases requiring manual configuration
Solution Approach 1:
The system merges the configuration process of multiple display devices into a single automated estimation operation. Instead of requiring separate manual configuration for each device, the estimation unit collectively determines the arrangement of all display devices based on resolution information, and the control unit coordinates their display areas in unison, combining multiple configuration tasks into one automated process

AI summary
A projector is included in a display system having a plurality of projectors. The projector includes: an image input unit having an input image inputted thereto; a projection unit displaying the input image; an estimation unit estimating an arrangement of the plurality of projectors, based on a resolution of the input image and a resolution of an image displayed by the projection unit; and a display control unit causing the projection unit to display an image showing an arrangement of the plurality of projectors, based on a result of estimation by the estimation unit.
