Pan Tilt Camera Automatic Orientation via Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera surveillance systems often fail to capture off-screen events of significance due to manual reorientation limitations, which can result in missing important events by the time the camera is adjusted.
Innovation Solution
Implementing a camera control system that automatically reorients pan and tilt cameras in response to sensor data from independent devices such as motion, sound, or light sensors, allowing the camera to autonomously adjust its angle of view to capture events of potential interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual reorientation of camera is used, then device complexity is reduced, but reliability of capturing significant events deteriorates
Solution Approach 1:
The system uses sensor data (motion, sound, light) as feedback to automatically trigger camera reorientation. When sensors detect significant events, the camera automatically adjusts its angle of view to capture these events, eliminating the need for manual intervention and improving reliability of event capture.
Solution Approach 2:
The camera system performs self-service by automatically reorienting itself based on sensor inputs. The system monitors its own operational context through sensors and autonomously adjusts its viewing angle without requiring external manual control, thereby improving event capture reliability.
2Loss of time
If manual reorientation of camera is used, then device complexity is reduced, but loss of time increases
Solution Approach 1:
The system performs preliminary action by having sensors continuously monitor the environment for significant events before they occur. When events are detected, the camera is already positioned to capture them immediately, eliminating the time delay associated with manual reorientation and reducing loss of time.
Solution Approach 2:
The patent replaces the mechanical manual reorientation system with an automated control system that uses sensor data to trigger camera movement. This substitution eliminates the time delay inherent in manual operation while adding automated sensing and control mechanisms.
3Reliability
If automatic reorientation with sensors is implemented, then reliability of capturing events is improved, but device complexity increases
Solution Approach 1:
The system achieves universality by using multiple sensor types (motion, sound, light) that can detect various kinds of significant events. This multi-functional sensing approach improves event detection reliability while sharing a common automated control architecture, thereby managing device complexity through standardized integration.

AI summary
Movements of a pan and tilt camera may be controlled by reorienting the camera in response to discrete information obtained by the camera from a related but independent device such as a sensor so that the camera can capture video of events of potential interest to a user. Such sensors can respond to multiple stimuli such as, for example, sound, motion, light, pressure, humidity, and/or the like. The cameras can include, for example, pan and tilt and zoom (PTZ) cameras that can be used in monitoring and surveillance operations. For example, the pan and tilt camera can be used as a surveillance camera at a home, business, vacation, or any other property.
