Movement-Triggered Auto Tracking for Manual Camera Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High network latency between a remote camera controller and the camera degrades the operability of manual control, making it difficult to capture objects within the imaging range, especially for professional cameramen who desire a secondary role for automatic tracking while maintaining predominant manual control.
Innovation Solution
A camera control apparatus with an input unit, first and second detection units to identify object movement, and a control unit that controls the imaging range based on object position for a predetermined time, allowing automatic tracking to operate secondary to manual control, reducing the impact of communication latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic tracking function is used to capture objects, then object capture capability is improved, but manual control predominance deteriorates
Solution Approach 1:
The system dynamically switches between automatic tracking mode and manual control mode based on real-time detection of object movement. When movement is detected, the system transitions to automatic tracking; when no movement is detected, it returns to manual control mode, allowing the control mode to be flexible and adaptive rather than fixed
Solution Approach 2:
The system changes the control parameter state by detecting object movement and switching between two distinct operational states: automatic tracking mode (when movement is detected) and manual control mode (when no movement is detected). This parameter change enables the system to adapt its control characteristics based on the current situation
2Loss of energy
If remote control is used to reduce travel costs, then operational cost is improved, but control latency worsens
Solution Approach 1:
The camera system performs self-service by automatically detecting object movement and initiating tracking mode without requiring remote operator intervention. This autonomous capability allows the camera to respond immediately to moving objects, compensating for the latency inherent in remote control operations
3Ease of operation
If manual control is used to maintain predominant role, then camera operator control is improved, but object tracking speed worsens
Solution Approach 1:
The system implements periodic monitoring of object movement and switches between manual and automatic modes in response to detected movement. This periodic detection and mode switching allows the system to maintain manual control as the default state while temporarily activating automatic tracking when needed, balancing operator control with tracking speed

AI summary
A control apparatus includes an input unit to which receives an image, a first detection unit configured to detect an object from the received image, a second detection unit configured to detect a start of movement of the detected object, and a control unit configured to, in a case where the start of movement is detected, control an imaging range of an imaging apparatus based on a position of the detected object for a predetermined time, and stop controlling the imaging range based on the position of the detected object after a lapse of the predetermined time.
