Camera Control Device Optimizing Imaging Data Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcasting systems that transmit and record images from multiple cameras struggle to optimize the output of imaging-related information, such as camera position and direction, leading to unnecessary data transmission and increased memory usage, particularly when cameras are stationary or in motion.
Innovation Solution
A control device that determines the usage mode of imaging devices, such as fixed, handy, or mobile cameras, to adjust the frequency and type of imaging-related information output, reducing unnecessary data transmission by omitting position information for stationary cameras and increasing output frequency for moving cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If imaging-related information is continuously output from all cameras, then the operator can easily grasp the state of each camera, but communication data volume and memory usage increase unnecessarily
Solution Approach 1:
The patent applies local quality by differentiating the output behavior of imaging-related information based on camera usage mode. Fixed cameras (mounted on tripods or walls) output position information at low frequency or not at all, while handy cameras (hand-held) output position information at high frequency. This localized differentiation optimizes communication data volume while maintaining operational effectiveness for each camera type.
Solution Approach 2:
The patent changes the parameter of output frequency based on usage mode determination. The control device determines whether each camera is in fixed or handy mode and adjusts the output frequency parameter accordingly. This dynamic parameter adjustment resolves the contradiction by adapting information output to actual operational needs.
2Loss of information
If position information is output for fixed cameras, then complete camera state information is available, but unnecessary data transmission occurs since fixed cameras do not move
Solution Approach 1:
The patent extracts position information output from the set of all cameras and applies it selectively based on usage mode. For fixed cameras, position information extraction is minimized or eliminated since their position is constant. For handy cameras, position information extraction is maintained at high frequency. This selective extraction eliminates unnecessary data transmission while preserving essential information.
3Measurement precision
If output frequency of imaging-related information is increased for handy cameras, then accurate position tracking is achieved, but communication data volume increases
Solution Approach 1:
The patent applies dynamics by making the output frequency adaptive rather than static. The control device dynamically adjusts the output frequency parameter based on real-time determination of camera usage mode. Handy cameras receive high-frequency position information updates for accurate tracking, while fixed cameras receive low-frequency or no updates. This dynamic adaptation achieves measurement precision where needed while minimizing communication data volume.

AI summary
Imaging-related information such as information regarding the position or orientation of a camera is output in an appropriate manner. A control device according to the present technology includes: a determination unit that determines a usage mode of an imaging device; and a control unit that performs output control of imaging-related information related to the imaging device on the basis of the usage mode determined by the determination unit. Performing the output control of the imaging-related information on the basis of the usage mode of the imaging device makes it possible to perform control so as not to output unnecessary information according to the usage mode of the camera. For example, in a case of a fixed camera that does not move, the imaging-related information as position information of the camera is not output, and in a case of a handy camera that is assumed to move, the imaging-related information as the position information of the camera is output.
