Projector Composite Image Boundary Line Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector technologies cannot allow users to explicitly designate the size of an image when projecting multiple images, as the size is determined by priority and number of pixels, limiting user control over the projected image sizes.
Innovation Solution
A display device with an image generation section, detection section, and control section that generates a composite image with a boundary line, allowing users to move a pointing body on the display surface to adjust the image sizes by moving the boundary line, enabling explicit size designation of projected images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image size is determined by priority and number of pixels, then the system can automatically manage multiple images, but the user cannot explicitly designate the size of the image to be projected
Solution Approach 1:
A boundary line is introduced as an intermediary element between the user and the image size control mechanism. The user interacts with the boundary line by moving it with a pointing body, and this boundary line mediates the separation and sizing of multiple images. The boundary line position directly determines the division point between images, allowing explicit size designation without complex settings.
2Loss of information
If multiple images are projected with automatic size determination, then the system can handle multiple inputs, but the user cannot visually recognize and adjust the sizes of the projected images
Solution Approach 1:
The boundary line is displayed in a distinct color (yellow) on the projection screen to provide visual feedback. This colored boundary line allows users to visually recognize the separation between images and understand the current size allocation. The visual presence of the boundary line transforms the invisible size determination into a visible, adjustable parameter.
Solution Approach 2:
The boundary line serves as a visual mediator that represents the invisible division between images. By making the boundary visible through color display, users can see exactly where images are separated and how much space each occupies, enabling informed adjustment decisions.
3Adaptability or versatility
If the boundary line is moved to adjust image sizes, then the user can explicitly designate image sizes, but the system requires interaction with a pointing body
Solution Approach 1:
The traditional mechanical or menu-based size adjustment system is replaced with a direct manipulation interface using a pointing body (such as a laser pointer or remote control). The user points at the boundary line position on the screen, and the system translates this optical input into boundary line movement and image size adjustment, replacing complex mechanical controls with simple pointing gestures.

AI summary
A projector includes an image generation section adapted to generate a composite image including a first image based on a first image signal, a second image based on a second image signal, and a boundary line indicating a position to be a boundary between the first image and the second image, a projection section adapted to display the composite image generated by the image generation section on a screen, a position detection section adapted to detect a position of a pointing body with respect to the screen, and a control section adapted to make the image generation section generate a composite image with a boundary line moved based on the position of the pointing body detected by the position detection section.
