Electronic Device Dual Display Object Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available web cameras lack functionality for processing or marking during video recording, making it difficult for users to observe changes in recorded videos, especially on mobile devices with small screens, which affects user experience.
Innovation Solution
An electronic device with a display interface featuring a first and second display area, where the original frames are displayed at an original scale in the first area and a zoom-in image of detected objects is displayed at a higher magnification in the second area, allowing for simultaneous panoramic and magnified views, enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If web cameras record videos without additional processing functions, then the device complexity is low, but the user experience deteriorates due to difficulty in observing object changes
Solution Approach 1:
The display interface is divided into a first display area showing the original video frame and a second display area showing the zoomed-in image of the moving object. This segmentation allows users to simultaneously view both the overall scene and detailed object changes, improving ease of operation without requiring complex external equipment
Solution Approach 2:
The patent transitions from a single-view display to a multi-dimensional display by adding a zoomed-in view dimension alongside the original view. This dimensional expansion enables users to perceive object changes more easily while maintaining the simplicity of the recording device
2Measurement precision
If web cameras provide only original scale display, then the device complexity is low, but the measurement precision of object changes deteriorates
Solution Approach 1:
The system extracts the moving object from the original video frame and displays it as a separate zoomed-in image in the second display area. This extraction enhances the measurement precision of object changes by isolating and magnifying the target object, while the processing complexity is managed through automated object detection algorithms
Solution Approach 2:
The patent creates a copied and magnified version of the moving object region from the original frame. This copying approach allows precise observation of object changes without altering the original recording, balancing measurement precision with processing simplicity
3Loss of information
If web cameras lack object detection and zoom functions, then the device complexity is low, but the loss of information about moving objects increases
Solution Approach 1:
The system performs preliminary object detection and identifies moving objects during video recording, then automatically generates zoomed-in views of these objects. This preliminary action prevents information loss about moving objects by proactively capturing and highlighting them, while managing processing complexity through efficient detection algorithms

AI summary
An electronic device includes a display interface with a first display area and a second display area, a memory and a processor. The memory stores at least one instruction. The processor is coupled to the memory. After loading the program instruction, the processor performs: accessing an image record file with a plurality of original frames; simultaneously displaying the original frames in the first display area and the second display area according to an original scale; detecting whether a first object exists in the image record file; and when the first object is detected in the image record file, displaying a zoom-in image with the first object in the second display area according to a first magnification scale and displaying the original frame corresponding to the zoom-in image in the first display area according to the original scale, wherein the first magnification scale is greater than the original scale.
