Solution Overview
Problem
Existing techniques for viewing two-dimensional images do not adequately enhance realism or provide efficient, desirable viewing experiences.
Innovation Solution
Convert mono images to stereo image pairs using viewpoint-based warping, depth-based warping, and boundary adjustment processes, while incorporating comfort parameter adjustments to address visual discomfort and preserve image details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If viewpoint-based warping is used to generate stereo image pairs from mono images, then 3D viewing experience is enhanced, but image resolution and detail quality deteriorate
Solution Approach 1:
The patent applies preliminary action by performing boundary adjustment and detail preservation operations before the warping process. The system identifies boundary regions in the mono image and prepares adjustment parameters in advance, then applies these adjustments prior to viewpoint-based warping. This ensures that critical boundary details are preserved and enhanced before the warping operation that would otherwise degrade image quality, thereby maintaining high resolution while enabling 3D viewing.
2Manufacturing precision
If depth-based warping is applied to preserve image resolution, then image details are maintained, but processing complexity increases
Solution Approach 1:
The patent applies local quality by implementing depth-based warping selectively in specific regions rather than uniformly across the entire image. The system identifies boundary regions and applies localized warping operations with adjusted parameters in these areas, while using simpler processing in other regions. This region-specific approach preserves image resolution and details in critical areas without unnecessarily increasing overall processing complexity.
3Ease of operation
If comfort parameter adjustments are made to reduce visual discomfort, then viewing comfort is improved, but processing time increases
Solution Approach 1:
The patent applies partial action by implementing comfort parameter adjustments selectively based on image characteristics and viewing conditions. The system analyzes the mono image to identify regions where comfort adjustments are most beneficial, then applies parameter modifications only to those specific areas rather than uniformly across the entire image. This selective approach improves viewing comfort in critical regions while minimizing the overall processing time required.

AI summary
Various implementations disclosed herein include devices, systems, and methods that convert a mono image to a stereo image pair. For example, a process may obtain an input image depicting a scene and determine a depth image corresponding to a subset of the pixels of the input image from a first viewpoint. The depth image may have a second resolution that is less than a first resolution of the input image. The process may further generate a coordinate mapping that maps positions in the depth image to positions in the input image and performs a first adjustment to the coordinate mapping to alter the coordinate mapping to correspond to a second viewpoint different than the first viewpoint. The process may further perform a second adjustment to the coordinate mapping to increase resolution and provide an output image corresponding to a view of the scene from the second viewpoint.
