Solution Overview
Problem
Existing multimedia systems rely on external sensors that fail to accurately reflect the environmental luminance and color temperature perceived by the user, leading to inadequate brightness and white balance adjustments.
Innovation Solution
A multimedia system with a remote sensor and wireless transmitter that senses environmental conditions near the observer, transmitting control signals to the display apparatus to adjust brightness and perform white balance, thereby reflecting the user's visual perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external brightness sensors are provided to automatically adjust display brightness, then the convenience of manual adjustment is improved, but the accuracy of representing user visual perception deteriorates because the sensor location does not reflect the actual environmental luminance where the user observes the display
Solution Approach 1:
The patent introduces a remote control device as an intermediary that contains the brightness sensor. This intermediary carries the sensor to the user's actual observation location, allowing accurate measurement of environmental luminance where the user truly perceives the display, while still enabling automatic adjustment functionality.
Solution Approach 2:
The patent moves the sensor measurement from the display apparatus location to the user observation location by using the remote control device as a portable measurement platform. This spatial dimensionality change allows the sensor to measure environmental luminance at the correct location that reflects user visual perception.
2Adaptability or versatility
If color temperature sensors are provided to perform white balance adjustment, then the congruity between image and nearby objects is improved, but the accuracy of reflecting user visual perception deteriorates for the same reason as brightness sensors
Solution Approach 1:
The remote control device serves as an intermediary carrying the color temperature sensor to the user's observation location. This allows accurate measurement of environmental color temperature where the user actually perceives the display, enabling precise white balance adjustment that reflects user visual perception.
Solution Approach 2:
The patent relocates the color temperature measurement from the display apparatus to the user observation position through the remote control device. This spatial relocation ensures the sensor measures the actual environmental color temperature affecting user perception.
