Subject-Aware Illumination System for Dynamic Lighting Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illumination systems require users to manually set the irradiation range, making the process complex and time-consuming.
Innovation Solution
An illumination system that includes an irradiation device, an information acquisition device, a storage, and a controller. The controller generates shape information of the subject by comparing subject information with background image information and sets an irradiation range for the irradiation device based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually sets the irradiation range using a control stick, then the irradiation can be controlled, but the operation becomes complicated and time-consuming
Solution Approach 1:
The system automatically detects the subject and determines the irradiation range without requiring manual user input. The control stick operation is replaced by automatic subject detection and range setting, allowing the system to serve itself in determining illumination parameters
Solution Approach 2:
The manual mechanical control stick operation is replaced by an optical detection system using a camera and image processing algorithms. The mechanical user interface is substituted with automatic image-based subject recognition and range determination
2Device complexity
If the irradiation range is set manually by the user, then the user has control, but the process becomes complex
Solution Approach 1:
The system automatically performs subject detection, shape information generation, and irradiation range determination without requiring complex manual user input. The control process is simplified by allowing the system to handle the complexity internally through automatic image processing and range calculation
3Ease of operation
If the system automatically detects the subject and sets the irradiation range, then the operation becomes simple, but additional devices are required
Solution Approach 1:
The camera device serves multiple functions: it captures images for subject detection, provides information for shape analysis, and enables automatic irradiation range determination. By making the camera multi-functional, the system achieves automatic control without adding excessive separate components

AI summary
An illumination system includes: an irradiation device that irradiates light to a subject located in front of a displayer that displays a background image; an information acquisition device that acquires subject information for identifying the subject; a storage that stores background image information on the background image displayed on the displayer; and a controller that controls irradiation by the irradiation device. The controller generates shape information of the subject on basis of a difference between the subject information acquired by the information acquisition device and the background image information stored in the storage, and sets an irradiation range where light is irradiated by the irradiation device on basis of the shape information.
