Solution Overview

Problem

Existing systems for adjusting external display devices, such as projectors, require users to monitor both the display screen and the projection screen simultaneously, leading to reduced user convenience due to the need to switch attention between the two.

Innovation Solution

A method and device that allow a first display device to display an image aiding input operations for adjusting a second display device, while also projecting this image and a reflection of the adjustment results onto the projection surface, enabling the user to perform adjustments without constantly switching focus between screens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the operation screen is displayed on the computer's display screen, then the adjustment can be performed with a clear view, but the user must watch both the display screen and projection screen simultaneously, reducing user convenience

Engineering Contradiction:
Improveadjustment visibilityVSAvoiduser convenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent merges the operation screen display function with the projection screen by projecting the operation screen image onto the projection screen alongside the content image. This allows users to perform adjustments by viewing only the projection screen, eliminating the need to switch attention between the computer's display screen and projection screen, thus resolving the contradiction between adjustment visibility and user convenience

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The projection screen is given dual functionality: it serves both as the content display surface and as the operation screen display surface. By enabling the projection screen to display both the content image and the operation screen image simultaneously, the system eliminates the need for a separate operation screen display device, improving user convenience while maintaining adjustment precision

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An adjustment method includes the steps of displaying, by a first display device, a first image used to help an input operation for performing an adjustment of a second display device different from the first display device, displaying, by the second display device, the first image and a second image in which a result of the adjustment is reflected, and outputting an adjustment parameter used to perform the adjustment to the second display device based on the input operation.
