Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices with stereoscopic display functions require lenses to be arranged transversely to capture images with different horizontal viewing angles, limiting their convenience and flexibility in generating stereoscopic images.
Innovation Solution
A method and apparatus that calculate a horizontal viewing angle based on vertical viewing angles between pixels and lenses, allowing the generation of a translation image even when lenses are not arranged transversely, using an image processing device to determine the depth of field and coordinates of pixels to create a stereoscopic image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If two lenses are arranged vertically in a portable electronic apparatus, then the device structure is compact, but the apparatus cannot generate stereoscopic images because both lenses capture images with the same horizontal viewing angle
Solution Approach 1:
The patent transforms the problem from horizontal viewing angle differentiation to vertical viewing angle differentiation. By arranging lenses vertically and calculating depth of field based on vertical viewing angles, the system enables stereoscopic image generation without requiring horizontal lens separation, thus maintaining compact device structure while achieving stereoscopic functionality.
2Adaptability or versatility
If two lenses are arranged transversely to generate left and right eye images with different horizontal viewing angles, then stereoscopic images can be generated, but the device becomes less convenient to operate and less flexible in positioning
Solution Approach 1:
The patent changes the parameter basis for stereoscopic image generation from horizontal viewing angles to vertical viewing angles. By calculating depth of field based on vertical viewing angles between pixels and lenses, the system maintains stereoscopic image generation capability while allowing flexible device positioning and orientation, greatly improving ease of operation.
3Adaptability or versatility
If vertical viewing angles between pixels and lenses are used to calculate depth of field, then stereoscopic images can be generated regardless of lens arrangement, but complex calculations are required to determine horizontal viewing angles from vertical viewing angles and depth of field
Solution Approach 1:
The patent introduces depth of field as an intermediary parameter that bridges vertical viewing angles and horizontal viewing angles. The image processing device first calculates depth of field based on vertical viewing angles, then uses this depth of field information to determine horizontal viewing angles, enabling flexible lens arrangement while managing computational complexity through a two-stage calculation process.
