Multi-Camera Overlay for Gesture-Controlled Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with a single camera on the front or rear surface have limited viewing angles, making it difficult for users to capture stable images, especially when the desired angle is outside the camera's field of view, and lack the ability to detect subject movement for automatic photographic functions.
Innovation Solution
Integrating multiple cameras with different viewing angles into the electronic device, allowing for the detection of subject movement and using gestures to trigger photographic commands, such as capturing images, adjusting settings, or performing consecutive photography.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single camera is used on the front or rear surface, then the device structure remains simple, but the viewing angle is limited and cannot capture images at certain angles
Solution Approach 1:
The patent divides the camera system into multiple independent cameras (first camera for front surface imaging, second camera for rear surface imaging, third camera for side surface imaging) to achieve wide-angle coverage. Each camera is positioned at a different location on the device, allowing the system to capture images from multiple angles simultaneously, thereby resolving the contradiction between viewing angle and device complexity.
Solution Approach 2:
The patent transitions from a single-point camera view to a multi-dimensional camera arrangement by positioning cameras on different surfaces (front, rear, and sides) of the device. This spatial distribution of cameras creates a three-dimensional imaging capability, enabling the system to capture subjects from various angles and perspectives that would be impossible with a single camera.
2Reliability
If a single camera is used, then the device structure remains simple, but the image stability is poor when user hand is unstable during capture
Solution Approach 1:
The patent merges images from multiple cameras (first, second, and third cameras) to create a composite image that maintains stability even when the user's hand is unstable. By combining the image data from different camera positions, the system can compensate for hand movements and maintain image quality, thereby improving reliability without requiring complex stabilization hardware.
Solution Approach 2:
The system uses image processing algorithms to analyze and compare images from multiple cameras, detecting movements and adjusting the capture process accordingly. This feedback mechanism allows the system to compensate for hand instability by identifying and correcting for movements in real-time, improving image stability without adding physical stabilization components.
3Extent of automation
If a single camera is used, then the device structure remains simple, but the automatic detection of subject movement is not possible
Solution Approach 1:
The patent makes the multi-camera system serve multiple functions: capturing images from different angles, detecting subject movement through gesture recognition, and triggering appropriate responses (such as opening the flash or adjusting settings). By positioning cameras strategically, the system can detect gestures and movements that would be invisible to a single camera, enabling automated responses without requiring additional sensors.
Solution Approach 2:
The system uses image data from multiple cameras as an intermediary to detect subject movement and gestures. By analyzing the images from different camera perspectives, the system can identify movements and trigger appropriate responses automatically, such as opening the flash or adjusting camera settings, thereby achieving automation through existing camera hardware.
4Adaptability or versatility
If multiple cameras with different viewing angles are integrated, then the range of possible viewing angles increases and movement detection becomes possible, but the device complexity increases
Solution Approach 1:
The patent divides the camera system into multiple independent cameras (first camera for front surface imaging, second camera for rear surface imaging, third camera for side surface imaging) to achieve wide-angle coverage. Each camera is positioned at a different location on the device, allowing the system to capture images from multiple angles simultaneously, thereby resolving the contradiction between viewing angle and device complexity.
Data Source
AI summary
An electronic device and a method for controlling photographic capture. A first image is acquired by a first camera having a first viewing angle. A second image is acquired by a second camera having a second viewing angle, the second viewing angle being different from the first viewing angle. The first image is overlaid with at least one object from the second image, or an icon corresponding to the object. The first camera and the second camera are mounted to a same surface, or to disparate surfaces relative to one another. Photographic capture or control is triggered in response to movement of the object.
