Light Source Identification for Immersive Display Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
External light sources in a room, particularly those not directly associated with a display device, reduce user immersion when using a television as a display device, especially when multiple people are present and various light sources with network connectivity are involved, making it impractical to block out external stimuli.
Innovation Solution
A light source identification system comprising a light sensing apparatus with a CMOS or CCD image sensor, position sensor, transmitter, and processor that maps and characterizes light sources in the environment, allowing for the modification of lighting conditions to enhance user immersion by controlling the output of identified light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external light sources are blocked out to improve user immersion, then user immersion is improved, but device complexity and practicality deteriorate
Solution Approach 1:
The patent extracts and identifies individual light sources in the environment using image sensors and processors, then selectively controls only those specific light sources rather than blocking all external light. This allows immersion improvement through targeted light management without requiring physical blocking mechanisms.
Solution Approach 2:
The system introduces an intermediary layer of light detection and control technology between the user and external light sources. Instead of direct blocking, the patent uses image sensors, processors, and network communications to mediate and adjust light source behavior, maintaining immersion while avoiding complex physical barriers.
2Illumination intensity
If multiple light sources with network connectivity are controlled, then lighting distribution is improved, but device complexity increases
Solution Approach 1:
The patent employs a multi-functional system where a single apparatus performs multiple functions: capturing images with image sensors, processing data to identify light sources, determining their locations, and controlling their operation. This universal approach improves lighting distribution without requiring separate complex systems for each function.
Solution Approach 2:
The system enables light sources to control themselves through network connectivity. Each controllable light source receives instructions from the processing apparatus and autonomously adjusts its operation, reducing the need for complex external control mechanisms while achieving improved lighting distribution.
3Reliability
If all light sources in the environment are identified and controlled, then user immersion is improved, but measurement and detection difficulty increases
Solution Approach 1:
The patent performs preliminary actions by capturing images of the environment and processing them to identify and locate light sources before control is needed. This advance detection and mapping of light sources simplifies subsequent control operations and improves immersion without increasing real-time detection complexity.
Solution Approach 2:
The system replaces complex mechanical detection methods with optical imaging and digital processing. Image sensors capture visual information about light sources, and processors analyze this data to identify and locate lights, substituting mechanical detection with more efficient optical and computational approaches.
