Image Projector Device With Integrated Recognition And Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image projector devices require a separate computer to function as a whiteboard, necessitating time and effort to set up and share drawings created by multiple users, as they need to switch connections and install specific software on each device, making it cumbersome to share images.
Innovation Solution
An image projector device equipped with a projection optical unit, storage unit, and control unit that allows users to project, display, and store images without the need for external devices, incorporating a recognition unit to recognize user actions and generate or edit drawings, and an input unit to receive and display external images, enabling seamless image sharing and editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a projector is used as a whiteboard without additional devices, then device complexity is reduced, but image storage and sharing capabilities are insufficient
Solution Approach 1:
The patent combines the projector, camera, storage unit, and control unit into a single integrated device. The control unit receives image data from the camera, stores it in the storage unit, and can project it back, eliminating the need for separate PCs or storage devices while maintaining full whiteboard functionality including image creation, storage, and sharing capabilities.
2Productivity
If multiple PCs are used for whiteboard collaboration, then image creation capability is improved, but connection switching and software installation time increase
Solution Approach 1:
The projector is designed to perform multiple functions: it can project external images, capture images of displayed content via its integrated camera, store captured images locally, and replay them. This multi-functionality replaces the need for multiple specialized devices (PCs, cameras, storage devices) and eliminates the time required for connection switching and software installation while maintaining collaborative whiteboard capabilities.
3Ease of operation
If drawing images are saved in individual PCs, then image creation is enabled, but image sharing becomes cumbersome
Solution Approach 1:
The patent integrates storage functionality directly into the projector through a shared storage unit. When the camera captures an image of a displayed drawing, the control unit automatically stores it in the storage unit, making it immediately accessible for projection and sharing with all participants. This eliminates the need for manual file transfer or distribution across multiple devices, simplifying the sharing process while maintaining ease of image creation.

AI summary
An image projector device includes a projection optical unit through which an image is projected and displayed, a recognition unit that recognizes a user's action related to processing of the image, and a control unit that generates and/or edits a drawing image based on the user's action recognized by the recognition unit and projects and displays the drawing image being generated and/or edited as a projected, displayed image through the projection optical unit.
