Solution Overview

Problem

Video display systems with transparent displays face visibility degradation issues when video images overlap backgrounds, as the background can obscure the video content, leading to reduced clarity and visibility for viewers.

Innovation Solution

A video display system comprising a transparent screen, a projector, and a video processing device that captures background and video image data, adjusts the video image based on background characteristics, and determines optimal display positions to prevent overlap, enhancing visibility by adjusting luminance, chromaticity, and contrast to ensure clear viewing of both video and background content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a transparent display device is used to enable viewing of both video image and background simultaneously, then the versatility and information transmission capability are improved, but the visibility of the video image degrades when it overlaps with the background

Engineering Contradiction:
Improvecapability to display video image while transmitting backgroundVSAvoidvisibility of video image
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by adjusting the video image characteristics (luminance, chromaticity, contrast) specifically in regions where the video image overlaps with the background. The video processing device identifies overlap regions and applies targeted adjustments to those specific areas, making different parts of the video image have different properties based on their relationship with the background, thereby resolving the visibility degradation issue while maintaining transparency functionality.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes physical parameters of the video image (luminance, chromaticity, contrast) to prevent visibility degradation. The video processing device modifies these parameters of the video image based on the background characteristics, particularly in overlap regions, to ensure the video image remains visible while allowing the background to transmit through the transparent display device.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the video image is adjusted to improve visibility, then the visibility of the video image is improved, but the natural appearance and background transmission may be compromised

Engineering Contradiction:
Improvevisibility of video imageVSAvoidcomplexity of video processing
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies preliminary action by performing video image adjustment in advance before the video image is displayed on the transparent display device. The video processing device pre-processes the video image to account for potential overlap with the background, incorporating visibility enhancement measures into the video signal before it reaches the display device, thereby simplifying the overall system complexity while ensuring visibility.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the video image processing is enhanced to prevent overlap with background, then the visibility is improved, but the device complexity increases

Engineering Contradiction:
Improvevisibility of video imageVSAvoidcomplexity of video processing device
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the video processing device to perform multiple functions: it processes the video image to enhance visibility, identifies overlap regions with the background, and adjusts video image characteristics all within a single integrated device. This multi-functional approach prevents the need for separate dedicated devices for each function, thereby managing device complexity while achieving improved visibility.

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

AI summary

A video display system (1) includes a display device (10) displaying a display video image containing a transmitted background and a video image indicated by a video signal, and a video processing device (30) converting, based on a characteristic related to the transmitted background, the video image indicated by the video signal to be transmitted to the display device (10).
