Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination control systems require dedicated devices like MPUs, leading to a complex configuration.
Innovation Solution
An illumination control system comprising a display device with a first controller, image processor, and storage, and an illumination device with a second image processor and light emitter, capable of wireless communication, where the storage stores image region information, and the controller transmits gradation data based on video data and image region information to control the light emitter.

Engineering Contradiction Analysis
1Reliability
If a dedicated device such as an MPU is used to control illumination based on video parameters, then the illumination control function is achieved, but the system configuration becomes complicated
Solution Approach 1:
The patent merges the illumination control function into the display device by integrating the controller and storage unit that generate gradation data directly within the display device. This eliminates the need for a separate dedicated control device (MPU), thereby achieving reliable illumination control while simplifying the overall system configuration. The display device now performs both display and illumination control functions through its integrated components.
2Ease of operation
If gradation data is transmitted from display device to illumination device, then synchronized color and brightness control is achieved, but wireless communication requirements increase system complexity
Solution Approach 1:
The patent uses wireless communication as an intermediary mechanism to transmit gradation data between the display device and illumination device. This allows synchronized color and brightness control without physical connections, maintaining ease of operation while managing communication requirements through standardized wireless protocols. The gradation data acts as the intermediary information that enables coordination between the two devices.
