Projection Video Display Edge Blending With Dynamic Menu Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video projection techniques, such as those described in Patent Document 1, do not adequately address the blending process on the edges of projection videos, lacking user control and adjustment mechanisms for optimal blending.
Innovation Solution
A projection type video display apparatus with a controller that allows users to adjust blending processes through a blending adjustment mode, featuring a menu image that automatically changes position based on the blending adjustment region, enabling precise control over brightness and curvature adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a blending process is performed automatically without user adjustment, then the operation is simple, but the blending quality and appropriateness are insufficient
Solution Approach 1:
The system dynamically switches between automatic execution mode and blending adjustment mode. In automatic execution mode, the blending process runs automatically for simplicity. In blending adjustment mode, the user can adjust blending parameters to improve quality. This dynamic mode switching resolves the contradiction by allowing both automatic operation and manual adjustment depending on the situation.
Solution Approach 2:
The system provides self-service through automatic blending execution for routine operations, reducing the need for manual intervention. However, when higher quality is needed, the system allows user adjustment of blending parameters. This combination of self-service automation with optional manual refinement resolves the contradiction between operational simplicity and blending quality.
2Device complexity
If the menu image is displayed at a fixed position, then the display is simple, but the menu may overlap with the blending adjustment region reducing visibility
Solution Approach 1:
The menu image position is dynamically adjusted based on the blending adjustment region position. When the blending adjustment region is detected, the menu image automatically moves to a position that does not overlap with it. This dynamic position adjustment resolves the contradiction by maintaining simple display control while ensuring menu visibility through automatic repositioning.
Solution Approach 2:
The controller acts as an intermediary that coordinates between the menu display function and the blending adjustment function. It detects when the menu image would overlap with the blending adjustment region and automatically repositions the menu to an appropriate location. This intermediary control resolves the contradiction without adding significant system complexity.
3Ease of operation
If the menu image position is manually adjusted by the user, then the position can be optimized, but the operation becomes more complex
Solution Approach 1:
The system provides self-service by automatically adjusting the menu image position to avoid overlapping with the blending adjustment region. This automatic adjustment eliminates the need for complex manual control mechanisms while maintaining optimal menu visibility. The system serves itself by detecting overlap conditions and repositioning the menu automatically.
Solution Approach 2:
The system performs preliminary action by automatically positioning the menu image in an appropriate location before the user needs to interact with it. This prevents overlap issues from occurring in the first place, eliminating the need for subsequent manual adjustments and reducing control complexity.

AI summary
A projection type video display apparatus is configured to include a projection optical system, an image processor, and a controller. The controller is configured to control the image processor to perform a blending process for partially changing the brightness of projection videos. The controller is configured to perform control to set a mode of the projection type video display apparatus to a blending adjustment mode in which a user adjusts the blending process performed by the image processor. In the blending adjustment mode, the controller is configured to perform control to generate a menu image of the blending adjustment menu and display the menu image in the projection video. In the blending adjustment mode, the controller automatically changes a display position of the blending adjustment menu according to a position of a blending adjustment region that is a region to be adjusted by the blending process.
