Projection Image Edge Vignetting for Seamless Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Projection devices often create a visible boundary between the projected image space and the real space, leading to a disconnection in the viewing experience.
Innovation Solution
A projection device that generates a blur image and applies a vignetting effect to the edge region, combining it with the original image to create a seamless transition between the projected and real spaces.

Engineering Contradiction Analysis
1Measurement precision
If a projection device projects an image onto a screen or space, then the image content can be displayed with high resolution and projection performance, but a visible boundary appears between the projected region and the remaining region, causing a disconnection in the viewing experience
Solution Approach 1:
The patent applies different image processing treatments to different regions of the projected image. Specifically, the edge regions undergo blur processing and vignetting effect application, while the central region maintains its original clarity. This local differentiation allows the projected image to seamlessly blend with the surrounding space, eliminating the visible boundary effect while preserving high resolution in the main viewing area
Solution Approach 2:
The patent modifies image parameters (blur radius, transparency, brightness) in the edge regions to create a smooth transition between the projected content and the real space. By dynamically adjusting these parameters, the system reduces the contrast between the projected region and its surroundings, thereby minimizing the visible boundary effect while maintaining overall image quality

AI summary
A projection device includes: a projector; at least one memory storing one or more instructions; and at least one processor, wherein the one or more instructions, when executed by the at least one processor, cause the projection device to: obtain a first image; generate a blur image, based on the first image; obtain a background image by performing image processing on an edge region of the blur image to exhibit a vignetting effect on the edge region; and control the projector to project a second image in which the background image and the first image are combined.
