AI Technical Summary

Technical Problem

Existing projection systems with multiple devices face challenges in controlling display content and timing across interconnected devices, which are often laborious and unstable due to wired or wireless communication issues.

Method used

A method where one projector projects optical communication signals onto a projection surface, and imaging devices capture these signals to control the projection operations of other projectors, allowing for synchronized and stable image projection without the need for direct connectivity.

Benefits of technology

Enables easy and stable control of multiple projector operations by decoding optical communication signals, reducing the risk of communication failures and enhancing projection efficiency and flexibility based on detected conditions.

Abstract

To provide a projection control method, a projection device, an imaging device, a program, a reflector, and a projection system capable of more simply and stably controlling projection operations in a plurality of projection devices.SOLUTION: In a projection control method, a first projector (102) projects an optical communication signal at a certain position within its own projectable range, and a second projector (101, 103) projects an image according to an optical communication signal obtained from imaging data at a certain position.SELECTED DRAWING: Figure 1
