Adapter for endoscope, processor for endoscope and endoscope system

A processor capable of inputting and outputting digital signals to and from an adapter for endoscope to which an endoscope is connectable, the endoscope being provided with an image pickup device which analog signals are inputted to and outputted from, wherein

• the adapter for endoscope comprises:
• an image pickup device driving signal generation circuit generating a driving signal for driving the image pickup device on the basis of a driving control signal from the processor;
• an image signal output circuit converting an analog image signal from the image pickup device to a digital image signal in a serial signal format and outputting the digital image signal to the processor;
• an endoscope identification information reception circuit receiving endoscope identification information which is identification information about the endoscope;
• an adapter identification information storage section storing adapter identification information which is identification information about the adapter for endoscope;
• an information transmission section transmitting the endoscope identification information and the adapter identification information to the processor;
• a parameter-for-adjustment storage section storing parameters for adjustment;
• and
• a control section performing control to store the parameters for adjustment received from the processor into the parameter-for-adjustment storage section according to a command to write the parameters for adjustment from the processor which is configured to receive the endoscope identification information and the adapter identification information, and read the parameters for adjustment stored in the parameter-for-adjustment storage section according to a command to read the parameters for adjustment from the processor and output the parameters for adjustment to the processor;
• and
• the processor comprises:
• an adjusted combination information storage section storing adjusted combination information showing whether predetermined adjustment processing has been performed or not for a combination of the endoscope identification information and the adapter identification information;
• and
• a control section judging existence or nonexistence of the adjusted combination information about a combination of the endoscope identification information and the adapter identification information received from the adapter for endoscope by referring to the adjusted combination information storage section;
• if the adjusted combination information does not exist, executing the predetermined adjustment processing, storing the parameters for adjustment obtained by the execution into the parameter-for-adjustment storage section of the adapter for endoscope and storing the adjusted combination information about the combination of the endoscope identification information and the adapter identification information into the adjusted combination information storage section;
• and, if the adjusted combination information exists, reading the parameters for adjustment stored in the parameter-for-adjustment storage section of the adapter for endoscope.
