Display Device Video Calling Camera Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video calling technologies do not provide a convenient method for users to perform video calls on larger screens, limiting user satisfaction and convenience, as they require manual operation of mobile devices for capturing images.
Innovation Solution
A system comprising a display device and a mobile device connected via a communication network, where the display device activates its camera upon receiving a video calling request, captures images for both the user and the counterpart, and displays a video calling screen image, while the mobile device controls the video calling operation and switches between devices based on user view detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video calling is performed on a mobile device, then portability and ease of operation are improved, but screen size and viewing experience deteriorate
Solution Approach 1:
The video calling function is segmented between two devices: the mobile device handles control operations and the display device handles video display and image capture. This allows each device to specialize in its strengths while working together as a unified system.
Solution Approach 2:
The mobile device acts as an intermediary controller that communicates with the display device via a communication network. It transmits control signals to activate the camera and receives video data for display, mediating between user input and the large-screen display output.
2Area of stationary object
If video calling is performed on a display device with large screen, then viewing experience and user satisfaction are improved, but automatic image capture and device coordination complexity increase
Solution Approach 1:
The patent merges the strengths of two different devices into a unified video calling system. The display device provides large-screen display and automatic image capture capabilities, while the mobile device provides easy control interface, creating a combined system that leverages both devices' advantages.
Solution Approach 2:
The display device is given multiple functions: it serves as both the display screen for video output and as the image capture device via its integrated camera. This multi-functionality reduces the need for additional specialized hardware while maintaining system capabilities.
3Ease of operation
If the display device captures images during video calling, then convenience for hands-free operation is improved, but camera activation control and coordination requirements increase
Solution Approach 1:
The display device performs self-service by automatically capturing images during video calling without requiring manual operation. Its integrated camera activates automatically when video calling mode is engaged, providing hands-free operation convenience while the device manages its own image capture functions.
Data Source
AI summary
A display device configured to communicate with a mobile device for video calling. The display device is configured to activate a camera, based on a video calling request received from a mobile device, obtain image data for a counterpart mobile device through a communication interface, and control a display to display a video calling screen image including a first image for the counterpart mobile device generated based on the image data and a second image obtained by the camera.
