Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable surveillance cameras used in construction sites face issues with increased computational load and battery consumption due to unnecessary activation of digital image stabilization and digital distortion correction functions, especially when digital zoom is activated, leading to delays in video data transmission and cumbersome operation deactivation processes.
Innovation Solution
A portable imaging device that automatically stops one digital image processing function when another is performed, such as stopping digital image stabilization when digital zoom is executed, to prevent simultaneous activation and reduce computational load, thereby improving usability and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital image stabilization function is activated, then video data blurring is suppressed, but computational load increases and battery consumption increases
Solution Approach 1:
The system dynamically adjusts the activation state of digital image stabilization based on whether the camera is in use or not. When the camera is not in use, the function is deactivated to reduce computational load and battery consumption. When the camera is in use, the function is activated to suppress video data blurring. This dynamic control resolves the contradiction by making the system adaptable to different operational states.
2Measurement precision
If digital zoom function and digital image stabilization function are both activated, then specific area monitoring is enhanced, but computational load increases and video data transmission is delayed
Solution Approach 1:
The system preliminarily determines whether digital image stabilization should be activated before allowing digital zoom to operate. When digital zoom is detected, the system preemptively deactivates digital image stabilization to prevent excessive computational load and video data transmission delays. This preliminary action resolves the contradiction by preventing the simultaneous activation of both functions, which would otherwise compromise video data transmission speed while maintaining monitoring precision through digital zoom alone.
3Area of stationary object
If digital distortion correction function is activated, then angle of view is increased, but computational load increases and battery consumption increases
Solution Approach 1:
The system dynamically controls the activation of digital distortion correction based on operational conditions. When the camera is not in use, the function is deactivated to reduce computational load and battery consumption. When the camera is in use and a wide angle of view is needed, the function is activated. This dynamic control resolves the contradiction by adapting the function's activation state to actual usage requirements.
4Use of energy by moving object
If worker manually deactivates digital image stabilization function, then computational load is reduced, but operation becomes cumbersome and time-consuming
Solution Approach 1:
The system automatically manages the activation and deactivation of digital image stabilization without requiring manual worker intervention. When the camera is not in use, the system autonomously deactivates the function to reduce computational load. When the camera is in use, it automatically activates the function to suppress blurring. This self-service mechanism resolves the contradiction by eliminating the need for manual operations while maintaining optimal performance.

AI summary
A portable imaging device is configured to: obtain video data through shooting; perform a first digital image processing on the video data; and stop the first digital image processing when performing a second digital image processing on the video data while the first digital image processing is being performed. The second digital image processing is different from the first digital image processing.
