Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capture devices lack the ability to seamlessly switch between different lens distortions and fields of view, limiting user flexibility in viewing and editing visual content.
Innovation Solution
A system that simulates multiple lenses by maintaining distortion and field of view consistency across selectable lenses, allowing users to modify visual content to match the characteristics of the selected lens, using a processor to apply anamorphic warps and ray tracing for distortion adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single lens is used to capture visual content, then the device structure is simple, but the user cannot change distortion and field of view
Solution Approach 1:
The patent creates a virtual copy of multiple lens characteristics through computational processing. Instead of physically installing multiple lenses, the system captures image data once and then applies different lens distortion and field of view characteristics through digital processing, allowing users to switch between lens types without physical changes to the device.
Solution Approach 2:
The system changes the optical parameters (distortion level, field of view) of the captured image through digital processing. By adjusting these parameters computationally, the patent enables multiple lens effects from a single physical lens, resolving the contradiction between versatility and structural simplicity.
2Adaptability or versatility
If multiple lenses are physically installed, then lens switching flexibility is improved, but the device complexity and size increase
Solution Approach 1:
Rather than physically installing multiple lenses, the patent creates virtual representations of different lens characteristics through software. The system captures a single image and then generates multiple versions with different distortion and field of view properties, eliminating the need for physical lens arrays while maintaining lens switching capability.
Solution Approach 2:
The patent replaces the mechanical system of physical lens switching with a computational system. Instead of moving physical lenses or switching optical paths mechanically, the system uses digital image processing to apply different lens characteristics, thereby reducing device complexity while maintaining versatility.
3Adaptability or versatility
If lens distortion is modified, then field of view adjustment is achieved, but image integrity may be compromised
Solution Approach 1:
The patent applies preliminary processing to capture high-resolution image data that contains sufficient information for multiple field of view representations. By capturing the full scene with a single lens first, the system preserves all original image information, then selectively crops and processes portions to create different field of view effects without degrading the underlying image quality.
Solution Approach 2:
The system applies different processing qualities to different regions of the image. Central regions maintain higher fidelity with minimal distortion, while peripheral regions undergo more significant transformation to achieve the desired field of view effects. This local differentiation preserves image integrity in critical areas while achieving versatility in others.

AI summary
Visual content of image(s)/video frame(s) may be captured through a lens of an image capture device. The optical characteristics of the lens may determine the field of view of the visual content and the distortion present within the visual content. Multiple selectable lenses may be provided to a user to modify the visual content. Multiple selectable lenses may include distortion consistency and field of view consistency between various selectable lenses. The visual content may be modified based on the selected lens to simulate capture of the visual content through the selected lens.
