Dynamic Camera Switching for Complete Object Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera switching methods in mobile terminals fail to ensure optimal photographing effects for objects, leading to poor image capture due to limitations in field of view and ambient light conditions.
Innovation Solution
A dynamic camera switching method that automatically determines the appropriate camera based on the location and size of the object in the frame, switching between cameras with different fields of view to ensure complete display and optimal photography effects, while maintaining a smooth transition to avoid sudden vision changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual camera switching or simple automatic switching based on focal length or ambient light is used, then the switching operation is simple, but the photographing effect of the to-be-photographed object cannot be ensured
Solution Approach 1:
The system continuously monitors the location and size of the to-be-photographed object in the current photographing picture, and automatically switches cameras based on this feedback information. The switching decision is made by detecting whether the object is completely displayed and its position relative to the picture boundary, creating a closed-loop control system that adapts to changing photographing conditions.
2Manufacturing precision
If a camera with small FOV is used to capture detailed object, then the photographing effect of the object is improved, but the object cannot be displayed completely in the picture
Solution Approach 1:
The system dynamically adjusts the camera selection based on real-time detection of the object's location and size in the photographing picture. When the object is detected to be incompletely displayed or positioned near the boundary, the system automatically switches to a camera with larger FOV to ensure complete display, creating a dynamic adaptation mechanism that balances detail capture with complete object visualization.
3Manufacturing precision
If camera switching is performed frequently to ensure optimal object capture, then the photographing effect is improved, but the system complexity increases
Solution Approach 1:
The system performs self-service by automatically detecting the object's location and size, determining whether complete display is achieved, and autonomously switching cameras without user intervention. The terminal itself completes the camera switching operation based on its own detection results, eliminating the need for complex external control systems or manual user operations.
4Manufacturing precision
If the terminal determines object location and size to switch cameras automatically, then the photographing effect is improved, but the processing time and computational load increase
Solution Approach 1:
The system performs preliminary detection of the object's location and size during the photographing process, and proactively switches cameras before the object becomes incompletely displayed. By continuously monitoring and predicting the object's position, the system makes switching decisions in advance, reducing the actual switching time and ensuring smooth transitions without noticeable delays.

AI summary
Embodiments relate to the field of terminals and disclose a camera switching method for a terminal, and the terminal. In those embodiments, when the terminal is installed with a plurality of cameras, automatic and dynamic switching between the cameras may be implemented based on a to-be-photographed object, thereby improving a photographing effect of the to-be-photographed object. In those embodiment, the terminal may display, in response to a first operation of enabling a photographing function by a user, a first photographing picture captured by a first camera, where the first photographing picture includes a to-be-photographed object. If the to-be-photographed object cannot be displayed completely in the first photographing picture, the terminal may switch from the first photographing picture to a second photographing picture captured by the second camera, and disabling the first camera, where an FOV of the second camera is larger than an FOV of the first camera.
