Mobile Camera Quick Capture via Long-Press Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for quick photographing on mobile devices require multiple steps and processes, making it cumbersome and time-consuming, which can result in missing fleeting scenes.
Innovation Solution
A method that detects a long-pressed physical button to activate the camera and enter a quick photographing mode, allowing the camera to preview the scene and capture it with a single operation, regardless of the device's state, without the need for additional button presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional multiple-step photographing method is used, then the camera application can be activated and photographing can be performed, but the process becomes cumbersome and time-consuming, causing fleeting scenes to be missed
Solution Approach 1:
The system performs preliminary actions by automatically activating the camera application and entering photographing mode when a long press on the physical button is detected, before the user completes the photographing action. This eliminates the need for manual activation and focusing steps, reducing the overall time required while maintaining operational simplicity.
Solution Approach 2:
The patent merges multiple separate operations (activating camera application, entering photographing mode, focusing) into a single integrated action triggered by the long press on the physical button. This consolidation reduces the number of steps from multiple sequential operations to one unified operation, directly addressing the contradiction between ease of operation and time loss.
2Productivity
If multiple processes of activating camera and pressing photographing button are required, then the camera can capture images, but the quick photographing cannot be achieved due to cumbersome processes
Solution Approach 1:
The system executes preliminary actions automatically upon detecting the long press event, including activating the camera application and transitioning to photographing mode. This eliminates the need for the user to manually complete these steps, thereby increasing photographing speed while reducing the perceived complexity from the user's perspective.
Solution Approach 2:
The camera system performs self-service by automatically activating itself and entering photographing mode in response to the button press, without requiring user intervention for these preliminary steps. This automation increases productivity by eliminating manual operations while the system handles the complexity internally.
3Adaptability or versatility
If the mobile apparatus is in standby or locked state, then the device is in a power-saving or secure state, but the camera cannot be activated for quick photographing
Solution Approach 1:
The system performs preliminary actions of activating the camera application and entering photographing mode immediately upon detecting the long press event, even when the device is in standby or locked state. This eliminates the need for sequential state transitions, thereby increasing adaptability across different device states while reducing the time required to reach the photographing state.
Solution Approach 2:
The patent implements dynamic state management where the camera system can transition from any device state (standby, locked, or normal) directly to photographing mode upon button press. This dynamic capability enhances adaptability by working across multiple states while minimizing transition time through direct state changes rather than sequential transitions.

AI summary
A method and a device for quick photographing based on a mobile apparatus, and a mobile apparatus are provided. A long-pressed state of a preset physical button is set as a triggering condition for quick photographing, a current state of the mobile apparatus is detected and processes are respectively performed based on different states of the mobile apparatus, and then the camera is activated to enter the photographing state; therefore, the method is applicable to the mobile apparatus in any state to perform quick photographing. Moreover, after the camera is activated, a current scene is photographed if it is detected that the preset physical button is released, while the user does not need to manually click the photographing button again for photography. Only one operation is required in the whole procedure, which is simple and quick, thereby achieving the quick photographing effectively.
