1. A method of calibrating an endoscope, the method comprising:
- receiving a first signal indicative of a type of electromagnetic radiation sensor associated with the endoscope;
selecting one or more calibration instructions based at least in part on the first signal;
defining a first calibration target, detectable by the electromagnetic radiation sensor for calibrating one or more settings of one or more components of the endoscope, based on the one or more calibration instructions;
displaying the first calibration target;
receiving a second signal from the electromagnetic radiation sensor, wherein the second signal is indicative of what portion of the first calibration target the electromagnetic radiation sensor detected;
determining one or more correction factors, configured to adjust the one or more settings of the one or more components of the endoscope, based on the second signal; and
defining a second calibration target detectable by the electromagnetic radiation sensor, wherein one or more characteristics of the second calibration target are based at least in part on the one or more calibration instructions and the second signal.

Abstract
Embodiments of the invention include an apparatus including an enclosure configured to receive an endoscope having an electromagnetic radiation sensor. The apparatus also includes an electromagnetic radiation source having at least a portion disposed within the enclosure. The electromagnetic radiation source is configured to emit electromagnetic radiation based on a calibration instruction. The electromagnetic radiation sensor is configured to receive at least a portion of the electromagnetic radiation when at least a portion of the endoscope is coupled to the enclosure.

10. An apparatus comprising:
-
an enclosure configured to receive at least a portion of an endoscope; an electromagnetic radiation source at least partially disposed within the enclosure, wherein the electromagnetic radiation source is configured to emit electromagnetic radiation based on a calibration instruction configured to calibrate one or more operational settings of the endoscope; and a processor configured to execute instructions to perform a method, the method including; receiving a first signal identifying an electromagnetic radiation sensor associated with the endoscope, wherein the first signal is indicative of a type of the endoscope; selecting the calibration instruction based on the first signal; defining a first calibration target based on the calibration instruction; displaying the first calibration target using the electromagnetic radiation source; receiving a second signal from the electromagnetic radiation sensor, wherein the second signal is indicative of what portion of the first calibration target the electromagnetic radiation sensor detected; determining one or more correction factors based on the second signal; and defining a second calibration target, wherein one or more characteristics of the second calibration target are based at least in part on the calibration instruction and the second signal. - View Dependent Claims (11, 12, 13, 14, 15)

16. An apparatus comprising:
-
an enclosure configured to receive at least a portion of an endoscope; an electromagnetic radiation source at least partially disposed within the enclosure; and a processor configured to execute instructions to perform a method, the method including; emitting electromagnetic radiation from the electromagnetic radiation source at a first time when the portion of the endoscope is received within the enclosure; receiving a signal from an electromagnetic radiation sensor of the endoscope, the signal being defined based at least in part on a portion of the electromagnetic radiation emitted at the first time and received by the electromagnetic radiation sensor while the portion of the endoscope is disposed within the enclosure; determining whether a responsiveness of the electromagnetic radiation sensor to the electromagnetic radiation satisfies a threshold condition based at least in part on the signal; and emitting electromagnetic radiation at a second time different than the first time, wherein one or more characteristics of the electromagnetic radiation emitted at the second time are based at least in part on the responsiveness of the electromagnetic radiation sensor, the received signal, and a calibration instruction associated with the endoscope. - View Dependent Claims (17, 18, 19, 20)
