Solution Overview
Problem
Existing electronic devices with multiple cameras struggle to quickly adjust the field angle for image capturing, especially when the photographer is also the subject and needs to capture a wide field angle.
Innovation Solution
An electronic device with lens switching means that allows switching between different lenses on its surfaces, including a first lens for standard image capturing and a second lens for wider angle image capturing, along with control means to manage the display of captured images from different lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single lens is used for image capturing, then the device structure is simple, but the field angle cannot be adjusted to capture wide-angle images when the photographer is the subject
Solution Approach 1:
The imaging system is segmented into multiple independent lens units (first lens and second lens) with different field angles. Each lens can be independently activated to capture images at different angles, allowing the system to adapt to various shooting scenarios including wide-angle self-portraits without requiring a complex continuously adjustable lens mechanism.
Solution Approach 2:
The electronic device incorporates multiple lenses serving different functions: the first lens for standard field angle capture and the second lens for wide-angle capture. This multi-functional design allows a single device to handle diverse imaging needs (portrait, landscape, self-portrait) without requiring separate dedicated devices for each function.
2Ease of operation
If multiple lenses are provided for different field angles, then the field angle can be adjusted, but the operation complexity increases making it difficult to swiftly capture images at desired angles
Solution Approach 1:
The control unit automatically determines which lens to activate based on the shooting scenario and user needs. When the photographer is the subject and wide-angle capture is required, the system can automatically switch to the second lens without requiring manual intervention, making the operation as simple as taking a standard photo while enabling swift adaptation to different shooting conditions.
Solution Approach 2:
The control unit monitors shooting parameters and automatically adjusts lens selection based on the detected scenario. The system provides feedback by displaying captured images from different lenses on the display unit, allowing users to review and select the desired angle, thereby simplifying the operation through intelligent automation and visual feedback.
3Adaptability or versatility
If lenses are arranged on both front and rear surfaces, then the adaptability for different shooting scenarios is improved, but the device structure becomes more complex
Solution Approach 1:
The lens units are distributed across different spatial dimensions (front surface and rear surface of the electronic device). This three-dimensional arrangement allows the system to capture images from multiple perspectives and angles simultaneously, greatly enhancing adaptability for various shooting scenarios including front-facing self-portraits and rear-facing group photos while maintaining a compact device structure.

AI summary
An electronic device having a first surface on which a first lens and a second lens with a wider angle than the first lens is arranged and a second surface on which at least a third lens is arranged, the electronic device comprising control means for controlling a captured image of the first lens to be displayed in response to issuing an instruction to display a captured image of a lens on the first surface, and controlling a captured image at a second field angle wider than the first field angle to be displayed in response to issuing an instruction to display a captured image of a lens on the second surface.
