Projector Automatic Setting Switching for Geometric Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector systems require cumbersome setting changes when the projector is detached and reattached from a pedestal, particularly for geometric correction, which burdens the user and increases the frequency of setting adjustments based on the installation location.
Innovation Solution
A method and system where a projector automatically switches between first and second setting values when attached or detached from a base apparatus, with both sets including geometric correction parameters, allowing the projector to adapt settings seamlessly based on its position and orientation, reducing the need for frequent user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projector is detached from the base apparatus and carried around, then the projector can be installed at different locations, but the settings need to be changed in accordance with the location, which imposes a burden on the user
Solution Approach 1:
The projector automatically detects whether it is attached to the base apparatus and autonomously switches between first setting values (when attached) and second setting values (when detached), eliminating the need for users to manually adjust settings based on installation location
Solution Approach 2:
The system pre-configures two distinct sets of setting values (first and second setting values including geometric correction parameters) corresponding to attached and detached states, so that the appropriate settings are automatically applied before the user needs to use the projector at a different location
2Manufacturing precision
If the projector settings are manually changed according to installation location, then the projection quality can be optimized, but the frequency of setting adjustments increases, which burdens the user
Solution Approach 1:
The projector continuously monitors its attachment state to the base apparatus and automatically switches between setting values based on this feedback, ensuring optimal projection quality is maintained without requiring manual intervention
Solution Approach 2:
The system autonomously manages setting adjustments by detecting attachment status and switching between pre-configured setting values, eliminating the need for users to spend time manually adjusting settings when moving between locations

AI summary
A projector controlling method including projecting, by a projector, a projection image by using first setting values with the projector attached to a base apparatus that specifies the direction in which the projector projects projection light and the position where the projector is installed, changing the settings of the projector from the first setting values to second setting values when the projector is detached from the base apparatus, and changing the settings of the projector from the second setting values to the first setting values when the projector detects that the projector is attached to the base apparatus, and the set of first setting values and the set of second setting values each including a parameter relating to geometric correction of the projection image.
