Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual-view recording methods on terminals require complex user adjustments to align human face proportions in front-facing and rear-facing viewfinder frames, necessitating time-consuming manual adjustments when backgrounds change.
Innovation Solution
An electronic device adjusts the zoom ratios of front-facing and rear-facing cameras collaboratively to align human face proportions automatically, reducing the need for manual user intervention and simplifying the adjustment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment of zoom ratios is performed to align human face proportions in dual-view recording, then human face proportions can be made consistent, but operation complexity and time consumption increase significantly
Solution Approach 1:
The system automatically detects human faces in both front-facing and rear-facing camera views, calculates the proportion differences, and adjusts the zoom ratios autonomously without requiring manual user intervention. The electronic device serves itself by performing the alignment operation that would otherwise require user input.
Solution Approach 2:
The system continuously monitors the human face proportions in both camera views, compares them against target values, and dynamically adjusts the zoom ratios based on the detected differences. This closed-loop feedback mechanism ensures consistent proportions while adapting to changing shooting conditions automatically.
2Manufacturing precision
If manual adjustment of zoom ratios is performed to align human face proportions, then proportion consistency is achieved, but preparation time increases
Solution Approach 1:
The system performs automatic detection and adjustment of zoom ratios before the actual shooting begins. By pre-aligning the human face proportions in the dual-view recording setup, the system eliminates the need for time-consuming manual adjustments during the shooting process itself.
Solution Approach 2:
The electronic device autonomously performs the proportion alignment operation without requiring user time and effort. The automatic detection and adjustment mechanism handles the entire process independently, significantly reducing the preparation time that would otherwise be spent on manual adjustments.
3Adaptability or versatility
If different zoom ratios are used for front-facing and rear-facing cameras to adapt to different device parameters, then camera performance is optimized, but human face proportion consistency deteriorates
Solution Approach 1:
The system dynamically adjusts the zoom ratios of the cameras based on real-time detection of human face proportions. Rather than using fixed zoom ratios, the system makes adaptive changes to maintain proportion consistency while still allowing each camera to operate at its optimal performance range.
Solution Approach 2:
The system changes the zoom ratio parameters of the cameras automatically based on detected proportion differences. By adjusting these parameters dynamically, the system maintains human face proportion consistency across different camera types and device configurations without sacrificing camera performance.

AI summary
This application provides a shooting method and a related device. According to the shooting method, an electronic device may adjust a human face proportion in a rear-facing viewfinder frame using a human face proportion in a front-facing viewfinder frame as a reference, or adjust a human face proportion in a front-facing viewfinder frame using a human face proportion in a rear-facing viewfinder frame as a reference. The electronic device may further implement collaborative zoom of front-facing and rear-facing cameras, to collaboratively zoom in or zoom out pictures in the front-facing and rear-facing viewfinder frames. In this manner, a shooting preparation time can be reduced, and human face proportions in front-facing and rear-facing viewfinder frames in a dual-view recording mode can be adjusted more quickly and simply, to make the human face proportions in the front-facing and rear-facing viewfinder frames consistent, so that a video meeting expectations of a user is obtained.
