Remote Camera Control With Image-Based Delay Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote image capturing systems experience decreased operation performance due to communication delays between the controller and the camera, leading to unintended camera operations when the user's control instructions are delayed.
Innovation Solution
An image capturing system that combines control from a first control apparatus (controller) and a second control apparatus (information processing apparatus) to reduce the impact of communication delays by integrating control instructions for direction and velocity, with the information processing apparatus handling velocity control and the controller handling direction control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote control via IP network is used, then user can control camera from remote location, but communication delay increases causing unintended operations
Solution Approach 1:
The control function is segmented into two independent control apparatuses: a first control apparatus (remote controller) that sends control instructions, and a second control apparatus (information processing apparatus) that receives captured images and generates supplementary control instructions. This segmentation allows the system to maintain remote control capability while compensating for communication delays through parallel processing paths.
Solution Approach 2:
The second control apparatus performs preliminary action by generating control instructions based on captured images before the delayed control instructions from the first control apparatus are executed. This allows the camera to be proactively adjusted based on real image data, compensating for the time loss in remote communication.
2Ease of operation
If control instruction transmission time is long, then remote operation is feasible, but operation performance decreases due to delay
Solution Approach 1:
The second control apparatus acts as an intermediary that receives captured images, analyzes them, and generates supplementary control instructions. This intermediary compensates for the performance loss caused by long transmission times by providing real-time control based on actual image data, thus maintaining operation effectiveness despite remote location.
3Device complexity
If single control apparatus is used, then system is simple, but cannot compensate for communication delay effects
Solution Approach 1:
The control system is divided into two independent control apparatuses with distinct functions: the first control apparatus handles user input and basic control instructions, while the second control apparatus handles image analysis and generates compensatory control instructions. This segmentation improves reliability by providing delay compensation without requiring a completely complex unified system.
Solution Approach 2:
The control instructions from both the first control apparatus (user operations) and the second control apparatus (image-based generation) are merged and integrated by the image capturing apparatus. This combining of multiple control sources maintains reliability by compensating for delays while keeping the overall system structure manageable through standardized integration.

AI summary
An image capturing system includes a first control apparatus, a second control apparatus, and an image capturing apparatus. The first control apparatus includes a first transmitting unit that transmits a first control instruction based on a user's operation to the image capturing apparatus. The second control apparatus includes a second transmitting unit that transmits a second control instruction generated based on a captured image received from the image capturing apparatus to the image capturing apparatus. The image capturing apparatus includes an image capturing unit, a third receiving unit that receives the first control instruction and the second control instruction, and a control unit that controls an image capturing process of the image capturing unit based on the first control instruction and the second control instruction. The time taken for communication of the first control instruction is longer than the time taken for communication of the second control instruction.
