Multi-Camera Subject Focus Switching for Dual-Subject Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices struggle to capture images focused on multiple subjects using a single camera, making it difficult to switch focus between subjects in a video.
Innovation Solution
The electronic device employs multiple cameras, each focusing on different subjects, allowing simultaneous capture and switching between videos focused on separate subjects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single camera is used to capture images, then the device structure remains simple, but it is impossible to capture images focused on multiple subjects simultaneously
Solution Approach 1:
The patent divides the imaging function into multiple independent cameras, each responsible for capturing a specific subject. The first camera captures the first subject while the second camera captures the second subject, allowing simultaneous multi-subject focus without requiring a single complex lens system to handle all subjects
2Measurement precision
If the focus is adjusted to capture one subject, then that subject is clearly focused, but other subjects become out of focus
Solution Approach 1:
Each camera is optimized for capturing a specific subject with appropriate focus settings. The first camera is configured with focus parameters suited for the first subject, while the second camera is configured for the second subject, allowing each to achieve optimal focus accuracy for its designated target
3Ease of operation
If a single camera captures video of multiple subjects, then the video file is easy to manage, but switching focus between subjects is difficult
Solution Approach 1:
The video capture function is segmented into multiple parallel video streams, with each camera independently capturing video focused on its designated subject. This allows seamless switching between subjects by simply switching between video streams without requiring complex focus adjustment mechanisms

AI summary
An electronic device according to an embodiment of the disclosure may include a first camera, a second camera, a display, and at least one processor electrically connected to the first camera, the second camera, and the display. The at least one processor may acquire a first image frame through the first camera, display the first image frame on the display as a preview, determine a first point corresponding to a user input within the first image frame in response to a reception of the user input through the display, determine a second point that is distinguished from the first point and satisfies a predetermined condition within the first image frame, acquire a first video focused on a first subject corresponding to the first point through the first camera, and acquire a second video focused on a second subject corresponding to the second point through the second camera. Various other embodiments drawn by the specification are possible.
