Camera Switching Logic for Obstructed Multi-Camera Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with multiple cameras face issues when a camera is covered by an object, leading to unnecessary image capture due to the inability to switch between cameras based on their arrangement state or photographing readiness.
Innovation Solution
An electronic device with a processor that determines the arrangement state of a cover and switches the photographing unit between cameras on different surfaces of the device, ensuring that only a functional camera captures images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera is selected without considering cover arrangement state, then the camera selection process is simple, but unnecessary image capture occurs when the camera is covered
Solution Approach 1:
The system determines the arrangement state of the cover before setting the camera to photographing ready state. This preliminary check prevents unnecessary image capture by identifying covered cameras in advance, allowing the system to select an appropriate camera before activation.
Solution Approach 2:
The system continuously monitors the arrangement state of the cover and adjusts camera selection based on this feedback. When the cover state changes, the system re-evaluates which camera should be active, ensuring that image capture only occurs from uncovered cameras.
2Productivity
If the system always sets the requested camera to photographing ready state, then the camera response is fast, but wasted energy and unnecessary image capture occur
Solution Approach 1:
The system performs a preliminary determination of the cover's arrangement state before activating the camera. This prevents energy waste by avoiding activation of cameras that are currently covered, while maintaining fast response for uncovered cameras.
Solution Approach 2:
The system changes the operational state parameter of the camera based on the cover arrangement condition. Only when the camera is determined to be uncovered does the system transition it to photographing ready state, optimizing energy consumption based on actual usage conditions.
3Adaptability or versatility
If multiple cameras are arranged on different surfaces, then photographing versatility is improved, but determining which camera to use becomes more complex
Solution Approach 1:
The system assigns different functional qualities to cameras based on their local position and cover arrangement state. Each camera's photographing capability is determined by its specific arrangement state relative to the cover, allowing versatile multi-surface photographing with simplified local decision-making.

AI summary
An electronic device is provided. The electronic device includes a housing, a plurality of cameras that are arranged on at least one surface of the housing, a display that is arranged on at least one surface of the housing to display image data obtained through at least one of the cameras, a memory that is arranged inside the housing to store the image data, a processor that is arranged inside the housing and is electrically connected to the cameras, the display, and the memory, and a cover that is arranged to cover at least a portion of the housing such that the at least a portion of the housing is opened and closed to provide at least a first arrangement state or a second arrangement state. The processor is configured to determine an arrangement state of the cover in response to a request signal to set at least one camera among the cameras to a photographing ready state for obtaining the image data, and to switch a photographing unit from the at least one camera to at least one other camera based on the determination result. In addition, various embodiments identified through the specification are possible.
