3D Display Depth Cue Control for User-Tuned Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display technologies are limited in enhancing both depth volume and depth range perception using monocular depth cues, and existing methods fail to provide adjustable and tunable depth perception for individual user preferences.
Innovation Solution
The disclosed Joint Shading and Contrast (JSM) framework adjusts monocular depth cues, including shading, texture, and motion parallax, to enhance both depth volume and range perception, using a depth analysis module, shading/contrast retargeting, and motion parallax modules, tailored to user information and image content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If binocular depth cues are used to provide depth perception, then depth perception effect is enhanced, but expensive special devices are required and visual fatigue is induced
Solution Approach 1:
The patent uses monocular depth cues as a copy or alternative representation of binocular depth perception. By enhancing monocular cues (shading, texture, motion parallax) in 2D images, the system creates a perceptual copy of 3D depth information without requiring actual stereoscopic display devices, thus resolving the contradiction between depth perception quality and device complexity
Solution Approach 2:
The system changes the parameters of monocular depth cues (shading intensity, texture density, motion parallax magnitude) to enhance depth perception. By adjusting these visual parameters in the image processing, the system achieves depth perception enhancement without needing complex binocular display hardware, thereby resolving the contradiction
2Measurement precision
If binocular depth cues are used to provide depth perception, then depth perception effect is enhanced, but visual fatigue is induced
Solution Approach 1:
The patent creates a monocular copy of depth perception information that mimics the effect of binocular vision without its harmful side effects. By enhancing monocular cues in 2D images, the system provides depth perception comparable to binocular cues but without inducing visual fatigue, as monocular processing does not strain the stereoscopic vision system
Solution Approach 2:
The system converts the limitation of monocular vision (lack of true depth perception) into a benefit by enhancing monocular depth cues. This approach transforms what was previously a weakness into a strength, providing depth perception without the visual fatigue associated with binocular stereoscopic displays
3Measurement precision
If monocular depth cues are enhanced, then depth perception is improved, but existing methods only consider one type of perception (depth volume or depth range)
Solution Approach 1:
The patent merges multiple monocular depth cues (shading, texture, motion parallax) and simultaneously enhances both depth volume perception and depth range perception. By combining these different cue types and perception dimensions in a unified processing framework, the system overcomes the limitation of existing methods that focused on only one perception type
Solution Approach 2:
The system creates a universal depth enhancement framework that simultaneously provides both depth volume perception and depth range perception through monocular cues. This multi-functional approach allows a single system to address multiple perception needs, enhancing adaptability and versatility compared to specialized single-function methods
4Measurement precision
If depth perception is enhanced for all users, then depth perception quality is improved, but individual user preferences and characteristics are not considered
Solution Approach 1:
The patent implements dynamic adjustment of monocular depth cue enhancement based on individual user characteristics and preferences. The system adapts shading, texture, and motion parallax parameters according to user profiles, making the depth perception enhancement customizable rather than static, thereby resolving the contradiction between quality and adaptability
Solution Approach 2:
The system changes the parameters of monocular depth cues based on user information. By adjusting shading intensity, texture density, and motion parallax magnitude according to individual user preferences and characteristics, the system provides personalized depth perception enhancement while maintaining high quality for all users
