Projector Detection Load Reduction via Connection-Triggered Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display apparatuses, such as projectors, face high processing loads when continuously detecting user manipulations, leading to increased computational demands and reduced efficiency.
Innovation Solution
The image display apparatus displays a predetermined detecting image when connected to an external apparatus, allowing for the detection of manipulations only when necessary, thereby reducing processing loads by stopping unnecessary detection processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If image recognition processing is continuously executed to promptly detect user manipulation, then detection speed is improved, but processing load increases
Solution Approach 1:
The system executes image recognition processing periodically based on connection status. When an external apparatus is connected, the manipulation detection unit activates to perform image recognition on captured images. When no external apparatus is connected, the detection unit remains inactive. This periodic activation based on connection events allows the system to maintain prompt detection capability when needed while avoiding continuous processing that would increase the processing load.
2Reliability
If manipulation detection is always active to ensure responsiveness, then detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The manipulation detection unit dynamically changes its operational state based on connection status. The connection detecting unit monitors whether an external apparatus is connected, and the manipulation detection unit activates only when connection is detected. This dynamic state transition ensures that the system maintains high detection accuracy and reliability when external interaction is expected, while conserving energy by remaining inactive when no external apparatus is connected.

AI summary
A projector includes a projection unit, an external I/F, an image I/F, a connection detecting unit, a manipulation detecting unit, and an instruction information generation unit. The connection detecting unit detects connection in the external I/F and the image I/F. The manipulation detecting unit causes the projection unit to project a detecting image when connection is detected and detects a manipulation performed with respect to the detecting image. The instruction information generation unit executes processing which is based on the detected manipulation.
