Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems face challenges in improving convenience regarding lighting, particularly when individuals in control target areas do not carry mobile equipment, or when factors such as foot position or activity amount are relied upon for control.
Innovation Solution
A lighting management apparatus and system that utilize image analysis to acquire analysis information, including the pose of individuals in a target area, to generate control signals for associated lighting equipment, thereby enhancing lighting convenience and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lighting control systems rely on mobile equipment or foot position detection, then control functionality is provided, but convenience deteriorates when individuals do not carry mobile equipment
Solution Approach 1:
The patent replaces mechanical/optical detection systems (foot position detection means, mobile equipment sensors) with a camera-based image recognition system. The control unit detects human presence and extracts pose information from captured images, enabling lighting control through visual recognition rather than requiring physical sensors or mobile devices.
Solution Approach 2:
The patent introduces a camera as an intermediary device between the user and the lighting control system. Instead of directly detecting foot position or mobile equipment signals, the camera captures images that are then processed to determine human presence and pose, serving as a mediating detection mechanism that works for all users regardless of whether they carry mobile equipment.
2Ease of operation
If simple presence detection is used, then ease of operation is improved, but lighting control precision deteriorates
Solution Approach 1:
The patent segments the human figure in the captured image into multiple detection regions, including the entire human figure and specific body parts such as the head. By dividing the detection task into multiple regions of interest, the system can extract precise pose information while maintaining overall system simplicity.
Solution Approach 2:
The patent applies different detection strategies to different regions of the human figure. The control unit extracts pose information specifically from the head region and other key body parts rather than treating the entire figure uniformly, providing localized precision where it matters most for determining lighting control parameters.
3Ease of operation
If continuous lighting control is provided, then lighting convenience is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic lighting control adjustments based on detected pose changes rather than continuous adjustment. The control unit monitors the captured images for pose changes and only adjusts lighting parameters when such changes are detected, reducing unnecessary control operations and associated power consumption while maintaining lighting convenience when needed.

AI summary
A lighting management apparatus (101) includes a first acquisition unit (111), and a signal generation unit (112). The first acquisition unit (111) acquires analysis information based on a result being estimated by using an analysis of an image being acquired by photographing a target area TA. The analysis information includes a pose of a person P present in the target area TA. The signal generation unit (112) generates a control signal for controlling one or a plurality of pieces of lighting equipment LE being associated with the target area TA, by using the analysis information and a usage purpose of the target area TA.
