Dual Camera Streaming Video Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices cannot simultaneously share streaming videos captured by front and rear cameras in real time with other devices.
Innovation Solution
An electronic device with an image processing module that captures and combines still images from both cameras, adjusts their sizes if necessary, and encodes them into a streaming video format for real-time sharing over a communication channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device captures and processes video from both front and rear cameras simultaneously, then the video sharing capability is improved, but the processing complexity and resource consumption increase
Solution Approach 1:
The patent divides the video processing task into separate streams for front camera and rear camera. Each camera's video feed is processed independently through its own encoding pipeline, then both streams are transmitted separately through the communication module. This segmentation allows simultaneous processing without overwhelming the system resources.
Solution Approach 2:
The image processing module and communication module are designed to handle multiple camera inputs universally. The same processing pipeline and communication protocol are used for both front and rear camera videos, allowing the system to scale to multiple cameras without requiring separate dedicated processing paths for each camera.
2Speed
If the device encodes and transmits video from multiple cameras in real time, then the sharing speed is improved, but the energy consumption increases
Solution Approach 1:
The image processing module performs preliminary encoding and preparation of video data from both cameras before transmission. By pre-processing the video streams and preparing them for transmission in advance, the actual transmission phase can proceed at high speed without requiring excessive energy during the critical sharing moment.
Solution Approach 2:
The system maintains continuous video capture, processing, and transmission operations for both cameras simultaneously. Rather than alternating between cameras or batching transmissions, the useful action of video sharing continues uninterrupted, ensuring real-time capability while optimizing energy usage through sustained efficient operation.
Data Source
AI summary
A method of creating and sharing a streaming video to other devices by an electronic device, which comprises a first camera and a second camera, is disclosed. A voice signal collected by the electronic device is encoded into digital audio data. The first camera captures first still images and the second camera captures second still images simultaneously. The first still images and/or the second still images are cropped and combined to generate combined images. The combined images are encoded into encoded images with a predetermined format. A streaming video is obtained by mixing the encoded images with the digital audio data and transmitted to other remote devices.
