Multi-Camera Image Synthesis for Medium Zoom Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The image quality of expanded images declines in the medium zoom range when using existing methods with multiple cameras, as they struggle to maintain clarity and resolution across different view angles.
Innovation Solution
An electronic device synthesizes an image from a first camera with multiple images from a second camera, where the second camera's images correspond to different angles of its lens assembly, adjusting the camera angles and image processing to combine these images effectively, thereby enhancing image quality in the medium zoom range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If images from multiple cameras with different view angles are synthesized to provide zoom function, then the zoom capability is improved, but the image quality in medium zoom range deteriorates
Solution Approach 1:
The patent divides the image synthesis process into multiple stages: acquiring images from multiple cameras with different view angles, performing view angle correction on each image, and then synthesizing the corrected images. This segmentation allows each stage to be optimized independently, maintaining image quality while achieving zoom capability.
Solution Approach 2:
The patent applies view angle correction by changing the parameters of the acquired images according to their respective view angles. This parameter transformation corrects the distortion introduced by different camera angles before synthesis, ensuring high image quality in the medium zoom range while maintaining the zoom functionality.
2Manufacturing precision
If a dedicated medium view angle camera is used to maintain image quality, then the image quality is improved, but the device complexity increases
Solution Approach 1:
The patent makes existing cameras with different view angles (wide-angle and telephoto) perform the function of a medium view angle camera through view angle correction and image synthesis. This multi-functionality approach eliminates the need for a dedicated medium view angle camera, reducing device complexity while maintaining image quality.
Solution Approach 2:
The patent creates a virtual medium view angle image by synthesizing and correcting images from existing cameras. This copying approach allows the system to replicate the function of a medium view angle camera without physically adding one, thereby reducing device complexity while maintaining image quality.
