Lenticular Mirror Emulation for Glasses-Free 3D Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lenticular displays do not effectively emulate a mirror without requiring a reflective surface or head-mounted devices for stereoscopic viewing.
Innovation Solution
A lenticular display system that captures images from multiple angles using dual image sensors, transforms and displays these images to create a stereoscopic view without a reflective surface, allowing users to see a three-dimensional mirrored view without additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reflective surface is used to create a mirror view, then a mirrored view is achieved, but the device complexity increases and requires additional hardware components
Solution Approach 1:
The patent uses image sensors to capture optical images of the user and processes these copies digitally to create the mirrored view, rather than using a physical reflective surface. The lenticular display then presents these copied and processed images to simulate the mirror effect without requiring actual reflection.
Solution Approach 2:
The patent replaces the mechanical/optical system of reflection with an electronic imaging and display system. Instead of relying on physical mirror surfaces and optical paths, the solution uses digital image capture, processing, and presentation through a lenticular display to achieve the same functional result.
2Reliability
If head-mounted devices are used for stereoscopic viewing, then a three-dimensional view is achieved, but the ease of operation decreases and additional hardware is required
Solution Approach 1:
The lenticular display serves multiple functions: it presents stereoscopic images without requiring head-mounted devices, simultaneously provides a mirrored view of the user, and eliminates the need for special viewing equipment. This multi-functional approach improves ease of operation while maintaining stereoscopic capability.
Solution Approach 2:
The lenticular display acts as an intermediary device that captures images through image sensors and presents them in a stereoscopic format directly viewable by the user, eliminating the need for head-mounted intermediaries. The display mediates between the capture system and the user's eyes, providing the stereoscopic effect through its optical structure.
3Measurement precision
If a reflective surface is used, then mirror accuracy is improved, but the device complexity and material requirements increase
Solution Approach 1:
The system creates accurate mirror images by capturing optical information with image sensors and processing it digitally, then displaying the processed copies through the lenticular display. This copying approach achieves mirror accuracy without requiring physical reflective materials.
Solution Approach 2:
The patent substitutes the physical reflective surface with an electronic imaging and display system. The optical reflection mechanism is replaced by digital image capture, processing, and presentation, eliminating the need for reflective materials while maintaining or improving image accuracy through digital processing.

AI summary
In one implementation, a method of operating a lenticular display is performed by a device including a processor, non-transitory memory, and a lenticular display. The method includes capturing, from a first camera location in a physical environment, a first image of a user. The method includes capturing, from a second camera location in the physical environment, a second image of the user. The method includes transforming the first image and the second image by horizontally flipping the first image and the second image. The method includes displaying, on the lenticular display, the transformed first image at a display angle corresponding to a first eye location of the user and the transformed second image at a display angle corresponding to a second eye location of the user.
