Imaging Control System Pan Tilt Direction Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of network cameras with pan and tilt drive mechanisms often confuse the pan direction with the tilt direction due to changes in the optical axis, leading to difficulties in accurately controlling the imaging direction.
Innovation Solution
An imaging control system that includes a pan change unit, a tilt change unit, and a display control unit to clearly differentiate and display the changes in the optical axis direction, allowing users to intuitively operate the imaging direction to a desired orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the optical axis is changed to a tilt direction, then the imaging direction can be adjusted vertically, but the pan direction on the display screen is changed, causing user confusion
Solution Approach 1:
The system displays visual feedback showing the relationship between tilt changes and pan direction changes. When the optical axis is tilted, the display screen shows updated directional indicators that reflect how the pan direction has changed relative to the tilted axis, allowing users to understand and compensate for the directional shift.
Solution Approach 2:
The display screen acts as an intermediary between the complex mechanical movements (pan and tilt) and the user's control inputs. By visually representing the changed pan direction after tilt, the display mediates the user's understanding and allows for more accurate control despite the mechanical coupling between pan and tilt movements.
2Adaptability or versatility
If rotation operation is performed to rotate the network camera about the optical axis, then the imaging direction can be adjusted, but the pan direction or tilt direction on the display screen is changed, making it difficult for users to operate
Solution Approach 1:
The display screen provides real-time visual feedback showing how rotation operation affects the pan and tilt directions. Directional indicators are updated to reflect the new orientation, allowing users to see the relationship between rotation input and the resulting changes in pan/tilt reference directions.
Solution Approach 2:
The system adds a rotational dimension to the control system while maintaining the existing pan and tilt control interface. By displaying how rotation affects pan and tilt directions on the same screen, the system integrates three-dimensional orientation control (pan, tilt, and rotation) into a unified two-dimensional display interface.

AI summary
An imaging control system for controlling a direction of an optical axis of an imaging unit is provided. The imaging control system includes a pan change unit configured to change the direction of the optical axis to a pan direction, a tilt change unit configured to change the direction of the optical axis to a tilt direction, and a display control unit configured to display the change direction to which the direction of the optical axis is changed by the pan change unit, corresponding to the change by the tilt change unit, together with an image captured by the imaging unit.
