Multi-Camera Subject Tracking via Simultaneous Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When using an electronic device with multiple cameras, users face challenges in maintaining focus on a subject while moving the device, which can result in defocused images or unintended subjects being focused.
Innovation Solution
The electronic device employs a processor to receive images from multiple cameras, identify a subject based on predetermined criteria, generate a cropped image of the subject, and display these images simultaneously on the device's screen, allowing for improved subject tracking and focus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user moves the electronic device to position the subject for photographing, then the subject can be positioned in the frame, but the focus may be deflected or unwanted subjects may be inadvertently focused
Solution Approach 1:
The patent replaces manual mechanical device movement with an automated optical system. Multiple cameras capture images from different angles simultaneously, and image processing algorithms automatically identify and track the subject of interest, eliminating the need for users to physically move the device while maintaining precise focus on the intended subject.
Solution Approach 2:
The patent employs multiple cameras with different angles of view to perform multiple functions simultaneously: capturing the subject from various perspectives, tracking subject movement, and maintaining focus accuracy without requiring device repositioning. This multi-functional approach resolves the contradiction by providing both ease of operation and focus precision through a single stationary device.
2Reliability
If multiple cameras with various angles of view are used, then subject tracking capability is improved, but device complexity increases
Solution Approach 1:
The patent divides the imaging function into multiple specialized camera units, each with specific angle of view characteristics. This segmentation allows each camera to optimize for particular tracking scenarios while the system as a whole achieves comprehensive subject tracking reliability. The complex function is broken down into manageable modular components.
Solution Approach 2:
The patent combines multiple camera feeds and image processing functions into a unified subject tracking system. By merging the data from various cameras and integrating automated subject identification algorithms, the system achieves reliable subject tracking while managing device complexity through coordinated operation of multiple components rather than requiring each component to be overly complex.

AI summary
An electronic device having a multi-camera, according to various embodiments of the present disclosure, includes: the multi-camera, a display, a memory, and a processor operatively connected to the camera, the display, and the memory. The processor may be configured to receive a first image being photographed at a first angle of view of the camera, receive a second image being photographed at a second angle of view of the camera, identify a subject in the first image according to predetermined criteria, generate a third image in which the identified subject is cropped according to a predetermined area of interest, and display the second image and the third image on at least a portion of an area in which the first image is displayed. Various other embodiments may be possible.
