Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cameras are used to capture images from different viewpoints, then the quality and authenticity of multiview images are improved, but the device complexity and cost increase
Solution Approach 1:
The patent creates virtual copies of the base image at different viewpoints through computational methods rather than using multiple physical cameras. The system replicates the base image multiple times and applies view synthesis algorithms to generate synthetic views, eliminating the need for multiple cameras while maintaining multiview image quality
Solution Approach 2:
The patent replaces the mechanical camera system with a computational image processing system. Instead of using multiple physical cameras to capture images, the system uses a single camera to capture a base image and then employs computer algorithms to synthesize multiple viewpoint images, substituting mechanical capture with computational generation
2Measurement precision
If multiple cameras are deployed to capture different viewpoints, then the depth accuracy is improved, but the ease of operation deteriorates
Solution Approach 1:
The system creates multiple copies of the base image and processes them computationally to extract depth information. By replicating the base image and applying synthesis algorithms, the system achieves depth accuracy without requiring multiple cameras or complex calibration procedures
Solution Approach 2:
The patent replaces mechanical depth measurement systems with computational depth extraction. Instead of using multiple cameras to physically measure depth, the system uses algorithms to analyze the base image and synthesize depth information, greatly simplifying the operation
3Ease of operation
If a single view image is replicated to create multiple views, then the ease of operation is improved, but the manufacturing precision of depth characteristics deteriorates
Solution Approach 1:
The patent applies parameter changes to the replicated images through view synthesis algorithms. By adjusting disparity parameters, depth maps, and geometric transformations during the synthesis process, the system maintains depth characteristic accuracy even though the base image is replicated multiple times
Solution Approach 2:
The system replaces physical depth capture mechanisms with computational depth synthesis. Instead of relying on multiple cameras to physically capture depth information, the system uses algorithms to generate depth characteristics from a single base image, maintaining precision through mathematical modeling

AI summary
A multiview image creation system and method create a multiview image from a single view image. Creating a multiview image includes importing a single view image and assigning the single view image to a first multiview image layer of a composite multiview image. Creating a multiview image further includes replicating the single view image into a plurality of view images of the first multiview image layer, converting a depth setting of the first multiview image layer into a plurality of shift values of corresponding view images based on an ordered number of the view images, and shifting the view images of the first multiview image layer according to the corresponding shift values. The plurality of multiview image layers may be automatically rendered in a predefined sequence as the composite multiview image on a multiview display.
