Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection technologies do not effectively support stacked or tiled projections of multiple images from different projectors, lacking user-friendly methods for designating and adjusting composite images on a projection target.
Innovation Solution
A control system and method that includes an information processing device to acquire and display a combined image from multiple projectors, allowing users to designate a composite image area and generate adjustment information for each projector to align and combine images accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple projectors are used for stacked or tiled projection, then the coverage area and brightness are improved, but the alignment precision and operational complexity deteriorate
Solution Approach 1:
The system captures a picked-up image of the projection target using a camera, displays it on a screen, and allows users to designate the composite image range. Based on this feedback, the system automatically generates adjustment amounts for each projector to align the projection images accurately, resolving the alignment precision issue in multi-projection setups
Solution Approach 2:
The system automatically calculates and generates adjustment information for multiple projectors based on the user-designated composite image range. This self-service mechanism eliminates the need for manual alignment adjustments, maintaining high precision while simplifying operation
2Area of stationary object
If multiple projectors are used for stacked or tiled projection, then the coverage area and brightness are improved, but the ease of operation deteriorates
Solution Approach 1:
The system merges the control of multiple projectors into a single unified operation. The user designates the composite image range once on a display screen, and the system automatically generates and applies adjustment amounts to all projectors simultaneously, making multi-projection as easy to operate as single-projection
Solution Approach 2:
The system performs automatic calculation and distribution of adjustment parameters without requiring users to manually configure each projector. This self-service approach significantly simplifies the operation of multi-projection systems while maintaining large coverage areas
3Manufacturing precision
If manual adjustment of each projector is performed, then the alignment precision can be improved, but the time consumption and operational complexity increase
Solution Approach 1:
The system performs preliminary capture of the projection target image and automatic calculation of adjustment amounts before actual projection. By preparing the adjustment information in advance based on the picked-up image, the system eliminates time-consuming manual adjustments while ensuring precise alignment
Solution Approach 2:
The system uses the picked-up image as feedback to automatically determine the optimal adjustment amounts for each projector. This feedback mechanism enables the system to quickly calculate precise alignment parameters without manual intervention, reducing adjustment time while maintaining high precision

AI summary
A control method includes: acquiring a picked-up image generated by a camera, the picked-up image including a first projection image and a second projection image; causing a display to display a screen including the picked-up image; accepting, via the screen, an operation of designating a range in which a composite image formed by combining the first projection image and the second projection image is formed on a projection target; generating first information including at least one first adjustment amount of the first projection image to form the composite image, based on the operation; and transmitting the first information to the first projector.
