Real-Time Display Luminance Calibration for Dynamic Viewing Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive computer simulations fail to credibly replicate environments due to technical shortcomings that affect user immersion based on their position within the system, leading to inconsistencies in image characteristics such as luminance and contrast.
Innovation Solution
A computing platform dynamically adjusts image characteristics in real-time by determining a user's position and view angle, adjusting luminance and color properties of zones on fixed display screens, including blend and non-blend zones, to enhance image contrast and maintain immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed display screens are used to replicate the environment in interactive computer simulations, then the system structure is simple and cost-effective, but the image characteristics (luminance, contrast) vary depending on user position, reducing immersion and credibility
Solution Approach 1:
The system dynamically adjusts luminance parameters of different zones on the display screen based on the user's real-time position and viewing angle. This dynamic adaptation ensures that image characteristics remain consistent and credible regardless of user position, resolving the contradiction between simple fixed display structure and reliable immersion experience
Solution Approach 2:
The system changes luminance parameters of specific zones on the display screen according to user position data. By adjusting these parameters in real-time, the system maintains consistent image quality and immersion credibility without requiring complex hardware changes, thus preserving ease of manufacture while improving reliability
2Illumination intensity
If multiple projectors are used to cover the display screen, then the luminance coverage is improved, but blend artifacts appear in overlap zones, degrading image quality
Solution Approach 1:
The system applies different luminance adjustment strategies to different zones on the display screen. Specifically, blend zones where projectors overlap receive specialized luminance correction to eliminate artifacts, while non-blend zones use standard adjustments. This localized quality control maintains high image quality across the entire screen while preserving the benefits of multiple projectors for luminance coverage
Solution Approach 2:
The display screen is divided into multiple zones including blend zones and non-blend zones. Each zone is independently adjusted for luminance based on its specific characteristics and the user's viewing angle. This segmentation allows precise control over image quality in different regions, eliminating blend artifacts while maintaining overall luminance coverage
3Reliability
If real-time dynamic adjustment of luminance is implemented based on user position, then immersion and image consistency are improved, but the system complexity and processing requirements increase
Solution Approach 1:
The system pre-divides the display screen into zones and pre-determines luminance adjustment strategies for each zone type (blend zones vs. non-blend zones). This preliminary organization simplifies real-time processing by providing a structured framework for adjustments, reducing the computational complexity while maintaining image consistency and immersion

AI summary
Methods, display system and computer readable medium for dynamically adjusting image characteristics in real-time for a user therein. In real-time, a determination is made of a dynamic user position facing one or more fixed display screens. In real-time, and taking into account the dynamic user position, luminance of a plurality of zones is adjusted in a stream of images computed for display on the one or more fixed display screens. The calibrated (or adjusted) stream of images is then displayed onto the one or more fixed display screens. A relative view angle between the dynamic user position and the one or more fixed display screens may be determined, taking into account in real-time the dynamic user position, while adjusting luminance. Adjusting in real-time while taking into account the dynamic user position, may also be performed on color properties of the plurality of zones in the stream of images.
