Perceptual 3D Display Control Using Shading and Motion Parallax
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for enhancing monocular depth perception are limited to improving either depth volume perception or depth range perception, failing to simultaneously enhance both, and often require specialized 3D display devices, which can induce visual fatigue.
Innovation Solution
The Joint Modeling of Shading and Contrast (JSM) framework, which includes a depth analysis module, shading/contrast retargeting module, and motion parallax module, adjusts shading, contrast, and motion parallax cues based on depth profiles to enhance both depth volume and range perception, allowing for tunable and controllable depth perception tailored to user preferences.

Engineering Contradiction Analysis
1Measurement precision
If binocular depth cues are used to provide depth perception, then depth perception effectiveness is improved, 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 to binocular depth cues, creating a simulated depth perception effect without requiring stereoscopic display devices. By manipulating monocular cues in the displayed image, the system replicates the depth perception experience of binocular cues using only standard 2D displays
Solution Approach 2:
The patent replaces the mechanical/optical system of binocular stereoscopy with a computational image processing approach. Instead of using dual displays or special hardware to create depth perception, the system uses algorithms to modify monocular cues in a single image, substituting a computational method for a hardware-based solution
2Device complexity
If monocular depth cues are enhanced, then specialized display devices are not required, but previous methods could only improve either depth volume perception or depth range perception, not both simultaneously
Solution Approach 1:
The patent merges multiple monocular depth cues (shading, contrast, texture, perspective) into a unified enhancement framework. By simultaneously adjusting these different cues based on depth maps, the system achieves both depth volume and depth range perception improvements that previous single-cue methods could not accomplish
Solution Approach 2:
The patent changes multiple image parameters simultaneously (shading intensity, contrast levels, texture density, perspective distortion) to achieve comprehensive depth perception enhancement. By coordinating changes across these different parameters rather than modifying a single parameter, the system overcomes the limitations of previous methods

AI summary
An image processing system and method is provided for controlling an amount of perceptual three-dimensional elements for a display. The method includes: receiving an input image; receiving user information concerning a user; adjusting an amount of perceptual three-dimensional elements within the input image to obtain an adjusted input image based on depth information of the input image and the user information; and displaying the input image as adjusted on a display. The user information may include user profile information and/or a predetermined perceptual 3D control input. The image processing system and method may be used to tune the amount of perceptual three-dimensional elements within the input image according to the user.
