Merging Front and Rear Camera Image Data for Video Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices can only selectively provide image data from either the front or rear camera during video communication, limiting the ability to simultaneously show the user and their background to the counterpart user.
Innovation Solution
A method and apparatus that merge image data from both the first and second cameras, allowing simultaneous display and transmission of the user's image and background by defining one as main and the other as sub-image data, with editing effects applied based on user gestures, such as size control, position change, and animation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image data from both front and rear cameras is simultaneously provided, then the video communication quality is improved, but the device complexity increases
Solution Approach 1:
The patent merges image data from the front camera and rear camera into a single composite image that is transmitted to the counterpart user. The image merging unit combines the two separate image streams, allowing both the user and background to be displayed simultaneously in one unified image, thereby improving video communication quality without requiring separate transmission channels.
Solution Approach 2:
The electronic device is designed to perform multiple functions: capturing images from both front and rear cameras, merging these images, and transmitting the combined result. This multi-functional approach allows a single device to handle complex video communication requirements that would otherwise require multiple separate components or devices.
2Loss of information
If image data from both cameras is merged and transmitted, then the information completeness is improved, but the processing time increases
Solution Approach 1:
The patent performs preliminary actions by continuously capturing and buffering image data from both cameras before the actual video communication transmission is needed. The image merging unit is pre-configured to combine these streams, so when transmission is required, the merging process can proceed efficiently without significant delay, reducing the perceived processing time.
Solution Approach 2:
The system maintains continuous image capture and merging operations from both cameras, ensuring that image data is always ready for transmission. This continuous processing eliminates idle time and ensures seamless video communication by keeping the image streams active and synchronized throughout the communication session.

AI summary
A method and an apparatus for obtaining image data for video communication in an electronic device are provided. In an embodiment, a method and an apparatus for providing a video communication function that simultaneously uses image data obtained via a plurality of cameras. In the method, first image data is obtained using a first camera. Second image data is obtained using a second camera. The first image data is merged with the second image data. The merged image data is transmitted to a second electronic device. Other embodiments are possible.
