Engineering Contradiction Analysis
1Ease of manufacture
If conventional stereoscopic image algorithms perform pixel shifting at different offset levels, then the stereoscopic image can be generated from two-dimensional images, but the differences of objects viewed by left and right eyes are ignored, resulting in suboptimal visual effects
Solution Approach 1:
The patent applies local quality by processing different depth levels with different pixel shifting offsets. Objects at different depths are shifted by different amounts to create appropriate parallax effects, while maintaining the depth information through depth level mapping. This allows the system to generate stereoscopic images from 2D images while preserving depth accuracy.
Solution Approach 2:
The patent introduces a depth dimension by mapping 2D image pixels to multiple depth levels. The depth level map creates a three-dimensional structure from two-dimensional input, allowing pixel shifting operations that preserve depth information. This dimensional transformation enables both ease of generation and accuracy of depth representation.
2Reliability
If depth information is used to generate stereoscopic images, then visual effects can be improved, but conventional algorithms fail to accurately represent depth levels
Solution Approach 1:
The patent performs preliminary action by creating a depth level map before generating the stereoscopic image. The depth level map pre-processes the 2D image to identify and categorize objects by depth, establishing a foundation for accurate pixel shifting. This preliminary depth analysis ensures that subsequent pixel shifting operations maintain depth level accuracy while improving visual effects.
