Patent ID: 8411138

Claim:
A camera head separated type camera device, in which a camera head and a camera control unit are connected by a cable, wherein the camera control unit includes: a control module configured to transfer a predetermined Direct Current (DC) voltage to a correction control module of the camera head; and a voltage measurement module configured to measure a voltage drop in the DC voltage which has been transferred from the correction control module without any processing, and wherein the camera head includes: a Low Voltage Differential Signaling (LVDS) conversion driver module configured to transmit a LVDS signal to the camera control unit; the correction control module configured to generate an amplitude correction value and a rising correction value based on the voltage drop in the DC voltage measured by the voltage measurement module; and a LVDS control module configured to control the LVDS conversion driver module based on the amplitude correction value and the rising correction value generated by the correction control module.
