Solution Overview
Problem
Current computer-generated night-vision simulations in display systems lack dynamic activation and realistic adaptation to user-equipped night-vision-enhancer devices, leading to potential damage and suboptimal image rendering.
Innovation Solution
A display system with a processor module that determines the activation of night-vision-enhancer devices by users and dynamically activates a night-vision mode, rendering images in a night-mode-adapted wavelength spectrum while ensuring correct geometry and stereoscopic rendering, and includes methods for tracking user positions and orientations to adjust image generation accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display system uses standard image generation without night-vision mode detection, then the system complexity is reduced, but the reliability of night-vision-enhancer devices is compromised and image rendering quality deteriorates
Solution Approach 1:
The system performs preliminary detection of night-vision-enhancer device activation status before rendering images. The processor module proactively identifies when the device is activated and pre-adjusts rendering parameters to prevent damage and optimize image quality, rather than waiting for damage to occur or adjusting reactively
Solution Approach 2:
The system implements a feedback mechanism where the processor module continuously monitors the activation state of the night-vision-enhancer device and adjusts the image rendering process accordingly. When the device is detected as activated, the system modifies the wavelength spectrum and other parameters, creating a closed-loop control system that adapts to user equipment status
2Adaptability or versatility
If the display system renders images in standard wavelength spectrum, then the manufacturing precision is simplified, but the adaptability to night-vision-enhancer devices is reduced and image rendering quality suffers
Solution Approach 1:
The image rendering system dynamically adjusts its parameters based on the detected activation state of the night-vision-enhancer device. The processor module changes the wavelength spectrum from standard visible light to the appropriate night-vision spectrum (typically enhanced infrared or near-infrared), and modifies other rendering parameters in real-time to match the device's operational characteristics
Solution Approach 2:
The system changes key rendering parameters including the wavelength spectrum, brightness levels, and contrast ratios when night-vision mode is detected. These parameter adjustments align the generated images with the spectral sensitivity of the night-vision-enhancer device, ensuring optimal display quality and device safety
3Manufacturing precision
If the display system does not detect viewer position and sightline, then the device complexity is reduced, but the immersion quality and image rendering accuracy deteriorate
Solution Approach 1:
The system applies local quality enhancement by focusing computational resources on tracking the viewer's sightline and position relative to the display. Rather than tracking every movement, the system specifically monitors the sightline to determine the activation state of the night-vision-enhancer device and adjusts rendering parameters locally based on this focused tracking data
Solution Approach 2:
The system replaces complex mechanical tracking systems with sensor-based detection methods. By using cameras, infrared sensors, or other detection devices to monitor viewer position and sightline, the system achieves accurate tracking without the mechanical complexity of traditional motion capture systems

AI summary
A method and a display system for dynamically activating a night-vision mode. The display system comprises a processor module that further comprises an image generator module. The processor module is for determining at least a head position of a user in the display system, the head position being used at least for geometry-correction purposes and, while determining the head position, determining that a night-vision-enhancer device is activated by the user. The processor module is further for activating the night-vision mode of the display system and the image generator module, upon activation of the night-vision mode of the display system, renders night-vision-enhanced images of a computer generated environment for display. The night-vision-enhanced images present a night-mode-adapted wavelength spectrum.
