Display Color and Brightness Adjustment With Privacy-Isolated Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ambient light conditions affect a user's ability to view a computer display, with existing color and brightness adjustment algorithms being inaccurate due to raw data from ambient light sensors, varying performance based on illumination types, and potential privacy concerns from using image sensors.
Innovation Solution
A system utilizing a first processor and a second processor to route image sensor data only to the second processor when not in use by an application, enabling accurate color and brightness adjustments using higher-resolution image sensor data combined with ambient light data, while preventing privacy breaches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image sensor data is routed to the first processor for color and brightness adjustment, then adjustment accuracy is improved, but privacy security deteriorates
Solution Approach 1:
The patent introduces a second processor as an intermediary between the image sensor and the first processor. The second processor performs color and brightness adjustment algorithms on image sensor data without allowing the first processor to access the raw image data, thus maintaining adjustment accuracy while protecting privacy by blocking direct access to sensitive data.
Solution Approach 2:
The patent segments the processing functions by separating the first processor (which handles applications and should not access image data for privacy reasons) from the second processor (which is dedicated to image sensor data processing and color/brightness adjustments). This segmentation allows the system to maintain high adjustment accuracy through specialized processing while preventing privacy breaches through architectural isolation.
2Object-affected harmful factors
If image sensor data is blocked from the first processor, then privacy security is improved, but adjustment accuracy deteriorates
Solution Approach 1:
The second processor acts as an intermediary that receives image sensor data, performs the necessary color and brightness adjustments using sophisticated algorithms, and outputs adjusted data to the display. This intermediary approach ensures privacy security by blocking the first processor from accessing raw image data while maintaining adjustment accuracy through dedicated processing capabilities.
3Device complexity
If ambient light sensor data alone is used for adjustment, then device complexity is reduced, but adjustment accuracy deteriorates
Solution Approach 1:
The patent merges data from multiple sensors (image sensor and ambient light sensor) to achieve superior color and brightness adjustment accuracy. The second processor integrates high-resolution image sensor data with ambient light sensor data, combining the strengths of both sensing approaches to overcome the limitations of using either sensor type alone.

AI summary
A system is provided comprising a display (104), a first processor (106), a second processor (108), an image sensor (112), and an ambient light sensor (114). On condition that the image sensor (112) is not in use by an application, image sensor data (116) is blocked from the first processor (106) and routed to the second processor (108), to thereby enable the second processor to execute a color adjustment algorithm (120) configured to use at least the image sensor data (116) and ambient light data (118) to adjust one or more color parameters (124) of content (126) displayed on the display (104), and to execute a brightness adjustment algorithm (122) configured to use at least the image sensor data (116) and the ambient light data (118) to adjust a luminance (132) of the display (104).
