Monitoring Camera Control via Angle-Range Icons and Live View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for controlling monitoring cameras require repeated manipulations for precise panning or tilting, and the presetting function has low precision due to motor limitations, leading to operational errors.
Innovation Solution
A method where a user I/O device displays live-view video and angle-range icons, allowing users to select and control panning or tilting at representative angles of these ranges, eliminating the need for precise presetting and reducing operational errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If presetting function is used to quickly pan or tilt to desired points, then operation time is reduced, but manufacturing precision of the monitoring camera is insufficient leading to accumulated operational errors
Solution Approach 1:
The system captures images at multiple preset points and transmits them to the terminal device. When the user selects a preset point, the system provides feedback by displaying the captured image from that point, allowing the user to verify whether the actual position matches the intended position. If not, the user can manually adjust and capture new images to create updated preset points, forming a closed-loop feedback system that compensates for motor precision limitations.
Solution Approach 2:
The system pre-captures images at multiple anticipated viewing points and stores them as preset points before the user needs them. This preliminary action allows the user to quickly switch between pre-prepared views without performing repeated manual panning operations, significantly reducing operation time while the feedback mechanism ensures accuracy.
2Manufacturing precision
If repeated manipulations are performed to achieve desired panning or tilting angles, then manufacturing precision can be achieved, but loss of time increases due to multiple operations
Solution Approach 1:
The system pre-captures images at multiple anticipated viewing points and stores them as preset points. This preliminary action eliminates the need for repeated manual panning operations, as users can directly select from pre-prepared views, significantly reducing operation time while maintaining the ability to achieve precise positioning.
Solution Approach 2:
The system creates copies of the monitoring scene from multiple preset positions by capturing and storing images at each position. Instead of requiring users to manually pan to each position repeatedly, the system provides copied views that can be instantly accessed, reducing operation time while preserving the ability to view scenes from precise angular positions.
3Ease of operation
If presetting function is used with low-precision motors, then ease of operation improves, but measurement precision deteriorates due to accumulated operational errors
Solution Approach 1:
The system displays captured images from preset points to provide visual feedback about the actual position achieved. This allows users to verify whether the low-precision motor reached the intended location. If the position is inaccurate, users can manually adjust, capture a new image, and update the preset point, thereby compensating for motor precision limitations through feedback-driven correction.
Solution Approach 2:
The system enables users to self-correct positioning errors by allowing manual adjustment and re-capture of preset points. When the motor's low precision causes positioning errors, users can independently adjust the camera to the correct position, capture a new image, and update the preset point, making the system self-correcting without requiring high-precision motors.

AI summary
Provided is a method of controlling a monitoring camera. In the method, a live-view video is displayed on a first region of a display panel, and a plurality of angle-range icons corresponding to panning angle-ranges or tilting angle-ranges is displayed on a second region of the display panel. When one of the plurality of angle-range icons is selected, a control signal for executing panning or tilting at a representative angle of a panning angle-range or tilting angle-range of the selected angle-range icon is transmitted to the monitoring camera.
