Dual-Camera Object Tracking for Tiny Preview Object Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to perform high-dynamic-range photographing or video recording on objects that are too small to be selected within the preview region of a camera application interface.
Innovation Solution
The electronic device uses a second camera with a greater focal length than the first camera to acquire a higher-resolution image, allowing it to identify and lock onto target objects within the preview image by displaying identifiers for those objects, enabling high-dynamic-range photographing or video recording even when the objects are too small to be manually selected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user selects the target object in the preview region to trigger locking, then high-dynamic-range photographing or video recording can be performed, but the method fails when the object is too small to be selected manually
Solution Approach 1:
The system performs automatic object detection and locking without requiring manual user selection. The processor automatically identifies target objects in the preview image and locks onto them, enabling the system to serve itself rather than relying on user intervention for small objects that are difficult to select manually
Solution Approach 2:
The patent replaces the manual mechanical selection process with an automated image processing and object detection system. Instead of requiring users to manually tap or select objects, the system uses computational algorithms to automatically detect, identify, and lock onto target objects based on image analysis
2Measurement precision
If a second camera with greater focal length is used to acquire higher-resolution images, then small objects can be identified and locked, but the device complexity increases
Solution Approach 1:
The system dynamically switches between the first camera and second camera based on the detected object size and distance. When small or distant objects need to be locked, the system automatically transitions to using the second camera with greater focal length, optimizing the imaging process without requiring both cameras to operate simultaneously
Solution Approach 2:
The patent makes the camera system multi-functional by equipping the device with two cameras having different focal lengths. The first camera handles general preview and close objects, while the second camera handles distant or small objects, allowing the system to perform multiple functions with a unified camera subsystem

AI summary
Embodiments of the present invention provide an object tracking method and an electronic device, and relate to the field of communication technologies. The solution includes: acquiring a first image through a second camera in a case that a preview image acquired through a first camera is displayed, where the preview image and the first image include a plurality of objects, the plurality of objects are images of a plurality of first physical objects, and a resolution of the first image is greater than a resolution of the preview image; displaying, according to the first image and in the preview image, at least one identifier used for indicating M target object(s) in the plurality of objects in the preview image, where M is a positive integer; receiving a first input for a first object in the M target object(s) in the preview image; and tracking a physical object corresponding to the first object and displaying an image of the physical object corresponding to the first object in response to the first input.
