PTZ Camera Panning Control Icon for Rapid Field of View Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional monitoring systems with PTZ (pan, tilt, zoom) functions require complex manipulations, such as using directional keys, which can be time-consuming, especially when rapidly changing the field of view to monitor urgent events.
Innovation Solution
A monitoring device and system that utilizes a panning control icon, allowing users to easily pan or tilt images through intuitive touch inputs like tapping, dragging, pinching, and flicking, with a processor controlling the display to display direction markers and adjust the icon's size and position, and optionally incorporating a gyro sensor for tilting.

Engineering Contradiction Analysis
1Ease of operation
If directional keys are used for panning or tilting, then the camera can capture images in different directions, but the operation becomes time-consuming and complex
Solution Approach 1:
The panning control icon is divided into multiple selectable areas, each corresponding to a specific panning direction. When a user selects an area, the camera instantly pans to the corresponding direction, eliminating the need for step-by-step directional key operations and significantly reducing the time to change field of view.
Solution Approach 2:
The patent introduces a graphical interface dimension (the panning control icon displayed on the screen) that maps to the physical camera movement dimension. Users interact with the 2D icon areas rather than repeatedly pressing directional keys, transforming a time-consuming sequential operation into an instant selection-based operation.
2Area of stationary object
If the panning range is increased to cover wider areas, then more monitoring coverage is achieved, but the complexity of controlling the pan and tilt increases
Solution Approach 1:
The panning control icon serves multiple functions: it displays the current camera orientation, provides directional guidance through area segmentation, and enables instant panning to selected directions. This single interface element replaces multiple separate controls, maintaining simplicity even as the panning range expands to cover wider monitoring areas.
Solution Approach 2:
The panning control icon acts as an intermediary between the user and the camera's wide panning range. Instead of directly managing complex tilt and pan coordinates, users interact with simplified icon areas that automatically translate to the appropriate camera movements, reducing control complexity while maintaining full access to the extended panning range.

AI summary
A monitoring device is disclosed. The monitoring device includes a display configured to display an image acquired by a camera; and a processor configured to: control the display to display a panning control icon including an area corresponding to a panning range of the image, detect an input of selecting one point from the area of the panning control icon, determine a target panning direction based on a position of the selected one point on the panning control icon, perform panning on the image in the target panning direction, and display a direction marker at the position of the selected one point.
