Electronic Device with Multi-Camera Capture for Multiple Subject Focus
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 videos.
Innovation Solution
An electronic device equipped with multiple cameras and a processor that can acquire and process images from each camera, allowing it to focus on different subjects independently through user input and predetermined conditions.
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 camera system into multiple independent camera modules (first camera and second camera), each capable of independently capturing images focused on different subjects. This segmentation allows simultaneous multi-subject capture while maintaining the functional simplicity of individual camera units.
Solution Approach 2:
Each camera module is designed with universal functionality to capture images independently, and the processor integrates outputs from multiple cameras to create composite images. This multi-functionality enables the system to capture both close-range and far-range subjects simultaneously using the same basic camera architecture.
2Measurement precision
If the lens is moved to focus on one subject, then sharpness of that subject is maximized, but other subjects at different distances become out of focus
Solution Approach 1:
The patent assigns different focus distances to different camera modules - the first camera focuses on close-range subjects while the second camera focuses on far-range subjects. This segmentation of focus zones allows each camera to achieve optimal sharpness for its designated subject distance range.
Solution Approach 2:
Each camera module is optimized for specific local quality requirements - the first camera is configured with lens parameters suitable for close-range focusing, while the second camera is configured for far-range focusing. This local optimization ensures high sharpness for each subject type without compromising the other.
3Reliability
If video is captured focused on a first subject, then the first subject is clearly recorded, but switching focus to a second subject requires recapture
Solution Approach 1:
The patent pre-configures multiple camera modules to simultaneously capture videos of different subjects at different focus distances. While the first camera records video focused on the first subject, the second camera simultaneously records video focused on the second subject, eliminating the need to stop and refocus when switching subjects.
Solution Approach 2:
Both cameras operate continuously and simultaneously to capture video footage of their respective subjects. This continuous parallel operation ensures that video recording never stops when switching between subjects, maintaining uninterrupted useful action throughout the capture process.

AI summary
An electronic device 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.
