Solution Overview

Problem

In web conferences and video calls using display devices with in-camera, the line of sight of a person watching an image on the screen often does not correspond to the line of sight of the person displayed on the screen, leading to difficulties in maintaining eye contact and effective communication.

Innovation Solution

A display device with multiple cameras positioned to overlap the display area, a controller selects the optimal camera based on the positions of the eyes within the image displayed, ensuring that the line of sight of the user can be aligned with the communication partner's line of sight, allowing for accurate capture and display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single camera is used for capture, then the device complexity is reduced, but the ability to align line of sight with the displayed image is compromised

Engineering Contradiction:
Improvecamera configurationVSAvoidline of sight alignment
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent divides the capture function into multiple independent camera units positioned at different locations. Each camera can independently capture images from its specific viewpoint, enabling the system to select the optimal camera based on the displayed image content and achieve proper line of sight alignment without requiring a single complex camera system.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If multiple cameras are positioned to overlap the display area, then the line of sight alignment is improved, but the device complexity increases

Engineering Contradiction:
Improveline of sight alignmentVSAvoidcamera configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements dynamic camera selection where the controller actively chooses which camera to use based on real-time analysis of the displayed image content. This dynamic adaptation allows the system to optimize line of sight alignment for different scenarios without requiring all cameras to be simultaneously active, thereby managing the complexity through intelligent control rather than physical complexity.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If the camera position is fixed, then the device complexity is reduced, but the adaptability to different display positions and scenarios is compromised

Engineering Contradiction:
Improvecamera configurationVSAvoidcamera selection flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent creates a multi-functional camera system where multiple cameras with fixed positions collectively provide adaptable capture capabilities. By having cameras positioned at different locations and enabling the controller to select from any of them based on the displayed image, the system achieves versatility in handling different display positions and scenarios while maintaining the simplicity of each individual camera's fixed installation.

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