1. A system for determining elapsed time for a surgical procedure conducted using an endoscope, comprising:
a memory that stores instructions; and
a processor that executes the instructions to perform operations, the operations comprising:
determining an insertion time of an endoscope inserted into a patient via monitoring camera parameters of a camera that is positioned within the endoscope to identify the insertion time of the endoscope into the patient;
determining a removal time of the endoscope from the patient via monitoring camera parameters to identify the removal time of the endoscope from the patient;
generating an elapsed surgery time based upon the insertion time of the endoscope into the patient and the removal time of the endoscope from the patient; and
wherein the operation of monitoring camera parameters to identify the insertion time of the endoscope into the patient comprises monitoring a rate of change of a camera exposure index to identify a point in time in which the endoscope is inserted into the patient.
