Solution Overview

Problem

Existing display control methods, such as those disclosed in JP-A-2005-151418, can cause flickering of projected images due to differences between content images and test patterns, leading to an unpleasant user experience.

Innovation Solution

A display control method that acquires first and second content images, determines a pattern image with a matching color scheme based on the first content image's color information, and displays the pattern image immediately after the first content image, thereby minimizing color scheme differences and reducing flickering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a test pattern with different color scheme is projected between content images, then image quality calibration can be performed, but flickering is perceived by users due to color scheme differences

Engineering Contradiction:

Improveimage quality calibrationVSAvoidflickering perception

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by making the test pattern's color scheme match the specific content image's color scheme. Instead of using a fixed universal test pattern, the system adjusts the pattern's colors locally to match each content image's characteristics (warm/cool tones, saturation levels), thereby eliminating flicker while maintaining calibration effectiveness for that specific content type.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system changes the color scheme parameters of the test pattern dynamically based on the content image being displayed. By analyzing the content image's color characteristics and adjusting the test pattern's hue, saturation, and brightness parameters accordingly, the system ensures seamless visual transition while maintaining the pattern's utility for quality calibration.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If a solid black image is used for calibration, then measurement is simplified, but the difference between black image and colorful test pattern causes flickering

Engineering Contradiction:

Improvecalibration process simplicityVSAvoidflickering between black and test pattern

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by pre-adjusting the test pattern's color scheme to match the content image before the calibration process begins. By analyzing the content image's color characteristics in advance and configuring the test pattern accordingly, the system eliminates the harsh transition from black to colorful patterns, reducing flicker perception while maintaining calibration simplicity.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If different color schemes are used for test patterns, then comprehensive calibration can be achieved, but user experience deteriorates due to noticeable color differences

Engineering Contradiction:

Improvecalibration coverageVSAvoidcolor difference visibility

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies dynamics by making the test pattern's color scheme adaptive rather than static. The system dynamically adjusts the pattern's color characteristics based on the content image being calibrated, ensuring the pattern blends seamlessly with the content while still providing sufficient contrast for accurate calibration across different content types.

Inventive Principle:
