Projection Apparatus Dynamic Adjustment Image Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projection apparatuses hinder accurate image adjustment due to the visual interference of grid charts used for selecting and adjusting image projection positions, making it difficult for users to recognize and correct the adjustment control points.
Innovation Solution
A projection apparatus that projects a first adjustment image for selecting the target position and a second adjustment image for fine-tuning the projection position, allowing users to easily identify and adjust the pixel positions without the grid chart interference, using a control unit to manage the image projection and user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a grid chart is displayed on the projection screen to indicate positions of adjustment control points, then the user can select positions for image adjustment, but the luminescence of the grid chart hinders visual recognition of the adjustment control points
Solution Approach 1:
The adjustment process is divided into two distinct phases with different display modes: (1) a grid chart display phase for position selection, and (2) a grid-free display phase for precise adjustment. This segmentation allows each phase to have optimized visual characteristics for its specific purpose.
Solution Approach 2:
The display mode dynamically changes based on the adjustment stage. The control unit switches between displaying the grid chart (when no adjustment control point is selected) and not displaying the grid chart (when an adjustment control point is selected), adapting the visual presentation to the current operational context.
2Adaptability or versatility
If the same grid chart is used for both position selection and adjustment phases, then the interface remains consistent, but the grid chart hinders accurate correction of projection positions during adjustment
Solution Approach 1:
The display system dynamically adapts its configuration based on the adjustment phase. The control unit determines whether to display the grid chart based on whether an adjustment control point has been selected, creating a context-dependent interface that optimizes for the current task.
Solution Approach 2:
The adjustment functionality is segmented into two operational modes: position selection mode (with grid chart) and position adjustment mode (without grid chart). This segmentation allows the system to provide different visual aids appropriate for each specific task.

AI summary
A projection apparatus includes a projection unit configured to project an image, an operation receiving unit configured to receive an operation, and a control unit configured to control the projection unit. The control unit controls the projection unit to project a first adjustment image for selecting a position to be subjected to an adjustment of the image to be projected by the projection unit. When the operation receiving unit receives an operation for determining the adjustment target position while the projection unit is projecting the first adjustment image, the control unit controls the projection unit to project a second adjustment image different from the first adjustment image in an area corresponding to the adjustment target position identified by the determination operation received by the operation receiving unit.
