Electronic Device Camera Switching for AR Video Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
AR devices may face communication challenges when outside the coverage of an access point, particularly if they only have short-range wireless communication and no cellular wireless communication, preventing them from receiving data such as AR content from a network.
Innovation Solution
An electronic device with a first camera, a communication module, and a processor that establishes a short-range wireless connection with an external AR device, determines the image data format, and selectively uses either the first camera or the AR device's camera to transmit images to a counterpart device in real time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If AR devices use only short-range wireless communication without cellular wireless communication, then device complexity is reduced, but communication reliability deteriorates when outside access point coverage
Solution Approach 1:
The electronic device acts as an intermediary between the AR device and the counterpart device. It receives image data from the AR device via short-range wireless communication and forwards it to the counterpart device through its own cellular communication module, enabling the AR device to communicate beyond its short-range limitations without adding cellular hardware to it.
2Speed
If image data is transmitted in real-time from AR device to counterpart device, then transmission speed is improved, but device complexity increases due to dual camera selection and packetization requirements
Solution Approach 1:
The electronic device extracts and assumes the complex image processing functions (camera selection, format determination, packetization) from the AR device. The AR device simply provides raw image data through short-range communication, while the electronic device handles all the complex processing and transmission logistics.
3Adaptability or versatility
If the electronic device selectively uses either its own camera or the AR device's camera, then adaptability is improved, but device complexity increases due to camera selection and format determination
Solution Approach 1:
The electronic device is designed with multi-functionality to handle multiple camera sources (its own camera and the AR device's camera), multiple communication methods (short-range and cellular wireless communication), and multiple image formats. This universal design allows it to adapt to different scenarios without requiring separate specialized systems.

AI summary
An electronic device is provided. The electronic device is configured to establish a short-range connection with an external device including a second camera, establish a connection for image transmission/reception with a counterpart device, determine a format of image data to be transmitted to the counterpart device, select one of the first camera of the electronic device and the second camera of the external device to acquire an image to be transmitted to the counterpart device, when the first camera is selected, packetize first image data acquired from the first camera according to the format, so as to transmit the packetized first image data to the counterpart device through the communication module, and when the second camera is selected, receive second image data from the external device, and packetize the second image data according to the determined format, so as to transmit the packetized second image data to the counterpart device.
