Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If large parallax is used in stereoscopic images, then the 3D effect is enhanced, but viewer comfort deteriorates causing dizziness and eye fatigue
Solution Approach 1:
The patent dynamically adjusts camera parameters including interaxial distance and parallax magnitude based on scene depth characteristics. By changing these parameters adaptively rather than using fixed large parallax, the system maintains strong 3D effects while preventing viewer discomfort
Solution Approach 2:
The system transitions from static parallax settings to dynamic adjustment based on real-time scene analysis. The camera automatically modifies parallax parameters according to the depth distribution of captured objects, enabling adaptive optimization between 3D effect strength and viewer comfort
2Manufacturing precision
If professional photographers manually configure parallax settings, then stereoscopic image quality improves, but operation complexity increases
Solution Approach 1:
The camera system performs automatic scene analysis and parameter optimization without requiring user intervention. The depth acquisition unit and processing unit work together to autonomously determine optimal parallax settings, eliminating the need for professional configuration while maintaining high image quality
Solution Approach 2:
The patent replaces manual professional configuration with automated computational systems. The processing unit calculates optimal parameters based on scene depth information, substituting the need for expert manual adjustment with algorithm-driven automation
3Manufacturing precision
If complicated calculation is performed to adjust camera parameters, then stereoscopic effect precision improves, but processing speed decreases and power consumption increases
Solution Approach 1:
The patent divides the complex parameter adjustment process into modular functional units: depth acquisition unit for scene analysis, parallax acquisition unit for parameter determination, and processing unit for image generation. This segmentation enables efficient parallel processing while maintaining precision
Solution Approach 2:
The system performs preliminary scene analysis to acquire depth information before capturing the main stereoscopic images. By pre-processing scene characteristics and determining optimal parameters in advance, the system reduces computational burden during actual image capture, improving response speed while maintaining precision

AI summary
The present invention provides a method and apparatus for adjusting stereoscopic image parallax and a stereo camera. The parallax adjusting method includes obtaining a depth range of a current scene. A preset parallax range may also be obtained according to a current viewing condition. Expected camera parameters of the current scene are calculated according to the depth range of the current scene and the preset parallax range. The stereo camera is adjusted according to the expected camera parameters and used to capture preprocessed stereoscopic images. Further, the captured preprocessed stereoscopic images are processed according to the expected camera parameters to make the preprocessed stereoscopic images suitable for being viewed under the current viewing condition. The disclosed method and apparatus can jointly adjust parameters of the stereo camera and captured stereo images to obtain images or videos with a maximum parallax as well as desired display effect under a specified condition.
