Projector Drawing Area Adjustment for Image Position Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector systems cannot utilize the entirety of the display panel for projecting images due to the need for an area to secure image movement, leading to inefficient use of the panel and potential image shifting.
Innovation Solution
An information processing method that allows users to enable or disable an adjustment function to maintain the position of a projection image, deciding on a drawing area that is either the full panel or a smaller area depending on the function's status, allowing for efficient image projection and panel utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an area where the panel image is not formed is provided on the display panel to secure an area to enable the movement of the panel image, then the projection image position can be corrected, but the entirety of the display panel cannot be used to form the panel image
Solution Approach 1:
The patent implements a dynamic drawing area adjustment mechanism that adapts the panel image formation area based on the correction function status. When correction is enabled, a smaller drawing area is used to allow image movement; when disabled, the full panel area is utilized for high-definition projection. This dynamic adaptation resolves the contradiction between position stability and panel utilization.
Solution Approach 2:
The system changes the parameter of drawing area size based on the operational mode. By switching between a first drawing area (when correction is disabled) and a second drawing area (when correction is enabled), the system optimizes both projection quality and position correction capability without physical modification to the display panel.
2Manufacturing precision
If the panel image is formed on the entirety of the display panel, then high-definition projection is achieved, but the panel image cannot be moved for position correction
Solution Approach 1:
The system dynamically switches between two operational states: one where the full panel area is used for high-definition projection without correction, and another where a reduced drawing area enables position correction. This dynamic state switching allows the system to adapt to different operational requirements without compromising either definition or adjustability.
Solution Approach 2:
The display panel is designed to serve multiple functions through the selectable drawing area mechanism. It can operate in a full-area mode for maximum definition and in a reduced-area mode for position correction, making the system universally applicable to different projection scenarios without requiring multiple physical panels.

AI summary
An information processing method includes: accepting a first input indicating whether to disable or enable an adjustment function to cause a position on a projection surface of a first projection image projected by a first projector to coincide with an initial position; deciding a first area as a drawing area that is an area where an image can be drawn on a display panel provided in the first projector, when the first input indicating that the adjustment function is disabled is accepted; and deciding a second area that is smaller than the first area, as the drawing area, when the first input indicating that the adjustment function is enabled is accepted.
