Composition Control Device for Imaging Subject Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing composition control systems for imaging devices, such as electric gimbals, face difficulties in adjusting the composition to an intended target when the subject is moving, and require complex pan and tilt operations for composition adjustment.
Innovation Solution
A composition control device and method that allows for intuitive composition adjustment by designating a target composition on a screen displaying the captured image, using touch and tracing operations to control the platform device and adjust the imaging direction accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pan and tilt operations are used for composition adjustment, then the platform device can be controlled to position the subject, but the operation becomes complex and difficult to adjust to the intended composition when the subject moves
Solution Approach 1:
The patent replaces manual pan and tilt mechanical operations with an automatic composition adjustment system. The control unit automatically calculates the required pan and tilt movements based on subject detection results and predetermined composition rules, substituting the mechanical manual adjustment process with an automated control system that references subject position data and composition parameters.
Solution Approach 2:
The system enables self-service composition adjustment by automatically determining the optimal composition based on detected subject information. The control unit autonomously adjusts the imaging device's composition without requiring manual pan and tilt operations, using the subject detection results and predetermined composition settings to self-correct and optimize the framing.
2Reliability
If manual pan and tilt operations are required for composition adjustment, then the user can adjust the composition, but the operability deteriorates when the subject moves rapidly
Solution Approach 1:
The system implements feedback by continuously monitoring subject detection results and using this information to automatically adjust composition. The control unit receives real-time subject position data, compares it with the current composition, and automatically makes adjustments based on predetermined composition rules, creating a closed-loop system that responds to subject movement without requiring manual intervention.
Solution Approach 2:
The patent applies preliminary action by establishing predetermined composition settings and rules before subject movement occurs. The system pre-defines composition parameters and adjustment rules that are automatically applied when subjects are detected, allowing the system to proactively prepare and execute composition adjustments rather than reacting to manual user input after movement has occurred.
3Productivity
If the composition is adjusted based on detected subject information, then the composition can be automatically optimized, but the system complexity increases
Solution Approach 1:
The control unit performs multiple functions: it manages subject detection results, determines composition based on predetermined rules, calculates required adjustments, and executes control signals. By consolidating these diverse functions into a single multi-functional control unit, the system achieves automatic composition optimization without proportionally increasing overall system complexity.
Solution Approach 2:
The patent merges the subject detection function, composition determination logic, and control execution functions into an integrated system. The control unit combines multiple operations (receiving detection results, determining composition, calculating adjustments, and controlling the imaging device) into a unified automated process, reducing the need for separate independent systems for each function.

AI summary
Operability is improved for an operation related to composition adjustment. Composition designation operation information is acquired that is operation information designating a composition of an imaging device and includes information of a designated position on a screen that displays a captured image of the imaging device, and an imaging range of the imaging device is controlled to adjust the composition of the imaging device on the basis of subject information corresponding to the designated position of the composition designation operation information. Thus, the adjustment to the target composition is performed on the basis of the subject information corresponding to the designated position on the screen displaying the captured image.
