Camera Cable Signal Integrity via Dynamic State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems with detachable camera head and main units face limitations in signal transmission flexibility and usability, particularly in extending cable length and maintaining signal quality when the units are separated.
Innovation Solution
A camera system that includes a determining section to differentiate between connection states via a first and second cable, allowing for signal processing and transmission adjustments, including amplification and compensation, to maintain signal integrity over extended distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the camera head unit and main unit are connected via a long cable for extended distance, then cable length extendibility is improved, but signal transmission quality deteriorates
Solution Approach 1:
The patent divides the cable connection into multiple segments by introducing an extension cable that can be connected between the camera head unit and main unit. The determining section identifies whether the system is in a first connection state (direct connection) or second connection state (extension cable connected), and the transmission section adjusts transmission parameters accordingly for each segment to maintain signal quality over extended distances
Solution Approach 2:
The transmission section dynamically adjusts transmission parameters based on the connection state detected by the determining section. When an extension cable is detected, the system changes transmission settings to compensate for the additional cable length and maintain signal integrity, making the system adaptable to different cable configurations
2Ease of operation
If the camera head unit is detached from the main unit for flexible usage, then ease of operation is improved, but signal transmission stability deteriorates
Solution Approach 1:
The determining section continuously monitors the connection state and provides feedback to the transmission section. This feedback mechanism allows the system to automatically adjust transmission parameters when the camera head unit is detached and connected via cable, ensuring stable signal transmission while maintaining the flexibility of detached operation

AI summary
A camera head unit including an image sensor configured to generate an image signal, a main unit configured to perform a signal process to the image signal, and first and second cables are included. Further, a determining section configured to determine whether a connection state is in a first connection state in which the camera head unit and the main unit are connected with each other via a first cable without a second cable or a second connection state in which the camera head unit and the main unit are connected with each other via the first cable and the second cable, and a transmission section configured to transmit the image signal between the camera head unit and the main unit at least via the first cable according to a determination result determined by the determining section are included.
