Projector Control Mode Shift for Seamless Image Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector control methods require users to temporarily exit geometric correction mode to access digital zoom or image position adjustments, leading to inconvenient back-and-forth navigation between menu screens.
Innovation Solution
A control method and projector configuration that allows seamless mode shifting from a geometric correction mode to a mode for adjusting image size or position, enabling users to perform changes without leaving the adjustment interface by accepting change operations and controlling the image transformation based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the projector displays separate menu screens for geometric correction and digital zoom functions, then each function can be accessed independently, but the user must navigate back and forth between menu screens to use multiple functions simultaneously, reducing operational convenience
Solution Approach 1:
The patent combines geometric correction and digital zoom functions into a single integrated menu screen. The display unit shows both the geometric correction menu and digital zoom menu simultaneously, allowing users to access and adjust both functions without navigating between separate screens. This merging of previously separate menu structures directly resolves the contradiction by improving operational convenience while maintaining functional independence.
Solution Approach 2:
The integrated menu screen serves multiple functions simultaneously - it displays geometric correction options, digital zoom controls, and projection image adjustments all in one interface. This multi-functional design allows the single menu screen to replace what were previously multiple separate menu screens, enabling users to access diverse functions without increasing overall system complexity.
2Measurement precision
If the projector requires users to exit geometric correction mode to access digital zoom, then each function can be controlled precisely, but the adjustment process is interrupted and requires temporary termination of one function
Solution Approach 1:
The patent enables continuous adjustment of multiple functions without interrupting the geometric correction process. Users can modify digital zoom parameters while geometric correction remains active and applicable. The projection image generation unit continuously applies both geometric correction and digital zoom adjustments in an uninterrupted workflow, eliminating the need to exit or temporarily terminate geometric correction mode.
Solution Approach 2:
The system allows users to pre-configure digital zoom parameters within the integrated menu screen before finalizing projection settings. The projection image generation unit is prepared to apply both geometric correction and digital zoom transformations simultaneously once the user completes adjustments, reducing the time spent on mode switching and navigation.
3Adaptability or versatility
If the projector uses separate control modes for geometric correction and image size adjustment, then each mode can be optimized independently, but the overall control process becomes more complex and requires multiple mode switches
Solution Approach 1:
The patent merges geometric correction control and digital zoom control into a single unified menu interface. The display unit presents both sets of controls together, and the projection image generation unit processes both types of adjustments in one coordinated operation. This reduces the number of separate control modes from two distinct modes to one integrated control system, simplifying the overall control process while preserving the adaptability of each individual function.

AI summary
A control method for a projector includes, executing a first mode to generate a projection image projected onto a display surface by modifying a shape of an input image, accepting a change operation to the input image for changing a size of a display image displayed as the projection image is projected on the display surface or a position of the display image on the display surface, during the execution of the first mode, and shifting from the first mode to a second mode to control a change to the input image based on the change operation, when the change operation is accepted.
