Stereoscopic Image Disparity Adjustment for Varying Screen Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D video processing methods fail to adapt the disparity between stereoscopic images effectively for different display devices, leading to suboptimal 3D effects when viewed on screens of varying sizes and formats.
Innovation Solution
A method that selects parts of stereoscopic images based on target screen size and format, calculates a disparity budget considering viewing conditions, and adjusts disparity information using a linear function to ensure optimal 3D effect adaptation across different display devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stereoscopic image is adapted for an original display device with specific size and format, then the 3D effect amplitude is optimized for that device, but the image cannot be optimally displayed on target screens with different sizes and formats
Solution Approach 1:
The patent changes the disparity parameter based on the target display device characteristics. The method calculates a disparity budget specific to each target screen size and format, then adjusts the disparity information accordingly. This allows the same stereoscopic content to be optimally displayed across multiple devices with different specifications while maintaining accurate 3D effect amplitude for each device type.
2Illumination intensity
If the disparity between left and right images is increased to enhance 3D effect amplitude, then the 3D perception is improved, but visual fatigue increases and viewing comfort deteriorates
Solution Approach 1:
The patent applies partial action by calculating a disparity budget that determines the optimal disparity level for each target display device. Instead of using maximum disparity uniformly, the method adjusts disparity to be sufficient but not excessive for each specific screen size and format. This ensures adequate 3D effect amplitude while preventing visual fatigue by avoiding overly large disparity values that would cause discomfort.
3Area of stationary object
If the stereoscopic image is resized to fit smaller display screens, then the image can be displayed on mobile devices, but the disparity information becomes inaccurate and 3D effects are degraded
Solution Approach 1:
The patent performs preliminary action by pre-calculating disparity budgets for multiple target display devices with different sizes and formats before actual display. The method prepares device-specific disparity adjustment parameters in advance, so when the stereoscopic image is resized for different screens, the pre-computed disparity information ensures accurate 3D effects are maintained without degradation.

AI summary
In an image processing method to display a stereoscopic image on a target screen, a disparity information (200) is associated with the stereoscopic image and is adapted for the display of the stereoscopic image on an original screen, the size of the original screen being different from the size of the target screen, the stereoscopic image comprising a first image (20) and a second image (21). In order to optimize the disparity of the stereoscopic image, the method comprises selecting a part of said first image according to at least one property associated with the first image; calculating a target disparity information associated with the selected part of the image according to the viewing conditions associated with the target screen and the original disparity information associated with the selected part of the first image.
