Transparent Display Blur Effect via Camera Perspective Warping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent displays in electronic devices, such as head-mounted systems, struggle to effectively blur the physical environment while allowing users to view both the physical and virtual content, as they cannot control the light emission to achieve a desired aesthetic appearance like opaque displays can.
Innovation Solution
A method involving a camera to capture images of the physical environment, warp them to the user's perspective, and display a blurred version of the images on a transparent structure, allowing the physical environment to be viewed through while overlaying a blurred image that aligns with the actual environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a transparent display is used to permit viewing of the physical environment, then the user can see through the display to the physical surroundings, but the display cannot effectively blur the physical environment to achieve desired aesthetic appearance
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture images of the physical environment, which are then processed and displayed as blurred versions on the transparent display. This mediator allows the system to achieve aesthetic blurring effects without directly controlling the light emission from the physical environment itself, resolving the contradiction between maintaining transparency and achieving aesthetic appearance control.
Solution Approach 2:
The patent creates a copied representation of the physical environment by capturing images with a camera and displaying blurred versions of these images on the transparent display. This copying approach allows aesthetic manipulation of the displayed content while the original physical environment remains unchanged and viewable through the transparent display, solving the contradiction between transparency and aesthetic control.
2Ease of manufacture
If a blurred image of the physical environment is displayed on the transparent display, then the aesthetic appearance is enhanced, but the clarity of the physical environment view is reduced
Solution Approach 1:
The patent applies blurring effects selectively to specific regions or portions of the displayed image rather than uniformly across the entire transparent display. This local quality approach allows aesthetic enhancement in certain areas while maintaining clear views of the physical environment in other areas, resolving the contradiction between aesthetic appearance and view clarity.
Solution Approach 2:
The patent applies partial blurring to the physical environment images displayed on the transparent display, rather than completely obscuring the view. This partial action approach enhances aesthetic appearance through selective blurring while preserving sufficient clarity for the user to still perceive and navigate the physical environment, balancing aesthetic enhancement with functional clarity.
3Ease of manufacture
If the physical environment is blurred to enhance aesthetic appearance, then the visual appeal is improved, but the user's ability to perceive real-world details is compromised
Solution Approach 1:
The patent applies partial blurring to enhance visual appeal while preserving critical real-world details. By selectively blurring certain aspects of the physical environment images while maintaining clarity in other areas, the system achieves aesthetic enhancement without significant loss of useful information about the real-world surroundings, resolving the contradiction between visual appeal and information preservation.

AI summary
To blur the physical environment viewable through a transparent display, a system may capture images of the physical environment using a camera, warp the images of the physical environment from the perspective of the camera to the perspective of a user's eye, and display a blurred version of the warped images. The transparent display overlays a blurred version of the physical environment over the physical environment such that the physical environment appears blurred. This type of blur effect may be applied across the entire physical environment that is viewable through the transparent display or across only a subset of the physical environment that is viewable through the transparent display.
