Projector Edge Blending Layout Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current projection devices face limitations in enlarging screen size without compromising resolution, contrast ratio, or brightness, particularly when using edge blending techniques to combine images from multiple projectors, as existing methods struggle to seamlessly overlap images without causing resolution or contrast loss.
Innovation Solution
A system and method for configuring an edge blending screen layout in a projector system, where a processor manages the output of a graphic user interface (GUI) image to ensure it does not overlap with the edge blending image by adjusting the layout of display areas between projectors, allowing for seamless image blending and enlargement without resolution or contrast loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If edge blending is used to enlarge screen size, then screen area is increased, but resolution and contrast ratio are compromised
Solution Approach 1:
The screen is divided into multiple projection areas, each handled by a separate projector. The processor segments the display content into first display areas (for GUI) and second display areas (for edge blending images), allowing each projector to focus on specific regions without compromising overall image quality
Solution Approach 2:
Different quality requirements are applied to different regions of the screen. The processor optimizes image parameters locally - maintaining high resolution and contrast in the first display areas for GUI elements, while applying edge blending techniques in the second display areas to achieve seamless transitions and enlarged coverage
2Loss of information
If GUI image is overlaid on edge blending image, then information completeness is improved, but image quality and seamless blending are compromised
Solution Approach 1:
The display area is segmented into distinct first display areas for GUI images and second display areas for edge blending images. This spatial segmentation prevents overlap between GUI elements and blended images, ensuring both information completeness and image quality are maintained without mutual interference

AI summary
A projector includes: a user interface; an image emitter; a communicator; and at least one processor operatively connected with the user interface, the image emitter, and the communicator, wherein the at least one processor is configured to: generate a first edge blending screen and control the image emitter to output a projection image of the first edge blending screen, based on receiving a request to output a graphic user interface (GUI) while the image emitter outputs the first edge blending screen, update a layout of the first edge blending screen, wherein the updated layout may include a first display area including the GUI and a second display area including a first blending image, and wherein the first display area does not overlap the second display area, and control the image emitter to output a projection image of the first edge blending screen including the updated layout.
