Multi-Device Display Control for Video Conferencing Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video conferencing systems lack the ability to effectively enhance the visibility of images displayed on multiple devices, leading to suboptimal user experience during video and audio communications.
Innovation Solution
A communication device and system that includes a storage unit for arrangement information, an arrangement-information setting unit, and a display control unit, which specifies and controls the display of images across multiple devices, allowing a first device to display captured images of a local and remote point, and a second device to display images supplied from either point, thereby optimizing image visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple display devices are used to display images in video conferencing, then the visibility and user experience are improved, but the complexity of managing and controlling display schemes increases
Solution Approach 1:
The patent divides the display system into multiple independent display devices (first display device and second display device), each capable of displaying different image content simultaneously. The display control unit segments the image distribution task by directing captured images to the first display device and supplied images to the second display device, thereby improving overall visibility while maintaining manageable complexity through structured segmentation.
Solution Approach 2:
The display control unit is designed with multi-functionality to handle different display schemes flexibly. It can dynamically determine whether to display captured images or supplied images on each display device based on received control instructions, allowing a single control unit to manage multiple display scenarios without requiring separate control mechanisms for each case.
2Device complexity
If captured images and supplied images are displayed on the same display device, then device complexity is reduced, but image visibility and user experience deteriorate
Solution Approach 1:
The patent implements segmentation by assigning different image sources to different display devices. The display control unit receives control instructions that specify which images (captured or supplied) should be displayed on which display device, ensuring that multiple image types are distributed across multiple devices to maximize visibility without overwhelming a single device.
Solution Approach 2:
Each display device is optimized for specific display purposes: the first display device is designated for captured images while the second display device is designated for supplied images. This local quality assignment ensures that each display device focuses on its designated function, improving the visibility and quality of displayed images while maintaining systematic control.
3Device complexity
If the display scheme is fixed for each display device, then control complexity is reduced, but adaptability to different communication scenarios decreases
Solution Approach 1:
The display control unit implements dynamic control by receiving control instructions that can change the display scheme in real-time. Based on these instructions, the control unit can dynamically adjust which images are displayed on which devices, allowing the system to adapt to different communication scenarios (such as switching between local and remote point displays, or between captured and supplied images) without requiring complex fixed configurations.
Solution Approach 2:
The system incorporates feedback mechanisms where the display control unit receives control instructions from external sources (such as remote communication devices or control systems) and adjusts its display behavior accordingly. This feedback loop enables the system to adapt to changing communication needs while maintaining relatively simple local control logic at each display device.

AI summary
According to an embodiment, provided is a communication device that performs communications of an image and audio. The communication device includes: a storage unit that stores therein arrangement information for specifying a display scheme for the image; an arrangement-information setting unit that sets arrangement information in the storage unit; and a display control unit that refers to the arrangement information and causes a plurality of display devices to display the image. The display control unit causes a first display device to display captured images of a local point and a remote point and causes a second display device to display an image supplied from an image supply device of the local point or the remote point.
