Lighting Control via 360-Degree Panoramic Image Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems for immersive experiences are limited to what is visible on the display device, failing to incorporate additional image characteristics from 360-degree panoramic images, which limits user immersion.
Innovation Solution
A method and system that control multiple lighting devices based on 360-degree panoramic image characteristics, mapping the image onto the devices to create a more immersive experience by rendering and controlling lighting settings for elements not directly visible on the display, such as a boulevard parallel to a beach scene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lighting devices are controlled based only on display device content, then control simplicity is maintained, but user immersion is limited
Solution Approach 1:
The patent transitions from 2D display content to 360-degree panoramic imagery, adding spatial dimensions to lighting control. By mapping panoramic image characteristics to lighting devices positioned around the viewer, the system creates immersive experiences that extend beyond the display screen into the physical environment.
Solution Approach 2:
The panoramic image is divided into multiple segments or regions, with each region mapped to specific lighting devices based on their spatial positions. This segmentation allows different parts of the panoramic image to control different lighting devices independently, enhancing immersion while maintaining manageable control complexity.
2Adaptability or versatility
If 360-degree panoramic image mapping is implemented, then user immersion is enhanced, but system complexity increases
Solution Approach 1:
The controller serves multiple functions: it processes panoramic image data, determines spatial positions of lighting devices, performs image-to-device mapping, and generates control signals. This multi-functionality consolidates complexity into a single controller rather than requiring separate systems for each function.
Solution Approach 2:
The controller acts as an intermediary between the panoramic image source and the lighting devices. It translates image characteristics into lighting control parameters and manages the complex mapping relationships, shielding users from the underlying system complexity while delivering immersive experiences.
3Loss of information
If additional image characteristics from panoramic images are incorporated, then content representation is improved, but processing requirements increase
Solution Approach 1:
The system extracts only the necessary image characteristics from the panoramic image that are relevant for lighting control, such as color information and spatial position data. By selecting and extracting only essential features rather than processing the entire panoramic image in full detail, the system reduces processing requirements while maintaining content representation quality.

AI summary
A method of controlling a plurality of lighting devices is disclosed. The method comprises obtaining a 360 degree panoramic image, rendering the 360 degree panoramic image at least partially on an image rendering device, obtaining positions of the plurality of lighting devices relative to the image rendering device, mapping the 360 degree panoramic image onto the plurality of lighting devices based on the positions of the plurality of lighting devices, such that each lighting device is associated with a part of the 360 degree panoramic image, determining, for each lighting device, a light setting based on an image characteristic of the part of the 360 degree image, and controlling each lighting device according to the respective light setting.
