Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional screen sharing technology duplicates the entire display screen, reducing the usability of digital multimedia data and limiting control to the transmitting device only.

Innovation Solution

An image mirroring system and method that determines a mirroring area of high importance in a source device's image and controls the layout of the mirrored image on a sink device, allowing selective mirroring and layout adjustment based on device specifications and user input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the entire display screen is duplicated and displayed on an external device, then the screen sharing function is achieved, but the usability of digital multimedia data is reduced

Engineering Contradiction:

Improvescreen sharing functionVSAvoidusability of digital multimedia data

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent divides the display screen into multiple regions of interest (ROIs) based on importance levels. Instead of duplicating the entire screen, only selected ROIs are transmitted to the external device. This segmentation allows selective sharing of important content while maintaining usability on the source device.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts specific regions of interest from the full screen content based on their importance. These extracted ROIs are then transmitted to the external device, separating the essential information from the rest of the screen content that remains on the source device.

Inventive Principle:

Principle #2Taking out (Extraction)

2Device complexity

If control of the mirrored image is limited to the transmitting device only, then the system complexity is reduced, but the usability of screen sharing is reduced

Engineering Contradiction:

Improvecontrol system complexityVSAvoidusability of screen sharing

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent enables both the transmitting device and the receiving device to control the mirroring process. The receiving device can adjust parameters such as ROI selection, mirroring ratio, and display layout, making the system more versatile and user-friendly while distributing control capabilities across both devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces dynamic control where the receiving device can adjust mirroring parameters in real-time based on user needs. The system transitions from static one-way control to dynamic bidirectional control, allowing flexible adaptation during the screen sharing process.

Inventive Principle:

Principle #15Dynamics

AI summary

An image mirroring system may comprise: a first display device configured to receive image data, and display a first image on the basis of the image data; and a second display device configured to receive mirroring image data from the first display device, and display a second image based on the mirroring image data. The first display device may sense the second display device capable of performing data communication, determine a mirroring area in the first image, generate the mirroring image data based on the mirroring area, and output the mirroring image data onto the second display device.
