Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera control systems in distributed scenarios lack flexibility and convenience, as they only support unilateral control and fail to synchronize control information between devices, leading to inadequate user experience and inaccurate control.
Innovation Solution
A method and apparatus for camera control that enables image and operation command synchronization between terminal devices, allowing for cooperative control by exchanging operation commands and status information, and supporting concurrent command execution and cancellation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If unilateral camera control is implemented in distributed scenarios, then device complexity is reduced, but control accuracy and user experience deteriorate due to lack of information synchronization
Solution Approach 1:
The patent merges control capabilities across multiple terminal devices by establishing bidirectional communication channels. Terminal devices exchange operation commands and status information, creating a unified distributed camera control system where multiple devices cooperate to achieve precise control without significantly increasing individual device complexity
Solution Approach 2:
The patent implements feedback mechanisms where terminal devices send status information about executed operation commands back to other devices in the distributed system. This feedback loop enables real-time synchronization of camera states, allowing devices to adjust their control actions based on current status, thereby improving control accuracy while maintaining manageable system complexity
2Loss of information
If control information is not exchanged between terminal devices, then information loss is minimized for each individual device, but overall system reliability deteriorates due to inability to synchronize camera states
Solution Approach 1:
The patent introduces status information as an intermediary element that mediates between different terminal devices. This status information acts as a common language that allows devices to understand and coordinate their control actions, enabling reliable synchronized camera control while each device maintains its own control information locally
Solution Approach 2:
The patent creates a universal communication protocol that allows different terminal devices to exchange both operation commands and status information. This universal interface enables any device in the distributed system to control the camera and understand its state, improving overall system reliability without preventing individual devices from retaining their own control information
3Ease of operation
If only unilateral control is supported, then ease of operation is improved for the controlling device, but adaptability deteriorates as the system cannot support cooperative control scenarios
Solution Approach 1:
The patent makes the camera control system dynamic by allowing the role of controller to switch between different terminal devices. Any device can initiate control operations or respond to commands from other devices, creating a flexible adaptive system that can accommodate various cooperative control scenarios while maintaining ease of operation through intuitive interfaces
Solution Approach 2:
The patent segments the camera control functionality across multiple terminal devices, with each device capable of independent control operations. This segmentation allows the system to adapt to different usage scenarios where different devices may take the lead in control, enhancing versatility while each device maintains simple ease-of-use characteristics
4Device complexity
If status information synchronization is not implemented, then device complexity is reduced, but control accuracy deteriorates due to inability to track command execution states
Solution Approach 1:
The patent implements feedback mechanisms where terminal devices send status information about executed operation commands back to other devices in the distributed system. This feedback loop enables real-time synchronization of camera states, allowing devices to adjust their control actions based on current status, thereby improving control accuracy while maintaining manageable system complexity
Solution Approach 2:
The patent enables terminal devices to automatically generate and exchange status information about their control operations without requiring complex centralized coordination. Each device independently tracks its own command execution state and communicates this information to others, achieving accurate status synchronization through simple self-service mechanisms

AI summary
A camera control method includes receiving image data from a second terminal device, where the image data is captured by the second terminal device in a photographing process, determining an operation command and status information, where the operation command is an operation command for the photographing process of the second terminal device, and the status information indicates an execution status of the operation command executed by the second terminal device, displaying a picture based on the image data, and displaying the execution status of the operation command on the picture based on the operation command and the status information.
