Abstract: A processing device includes a processing circuit configurable according to a type of an endoscope, and a control circuit configured to detect a connection state of the endoscope, and measure a disconnection time from disconnection to reconnection. The control circuit is also configured to determine that currently and previously connected endoscopes are of the same type when the disconnection time is shorter than a predetermined time, reconfigure the processing circuit according to the type of the endoscope when it is determined that the currently and previously connected endoscopes are not of the same type, and not reconfigure the processing circuit when it is determined that the currently and previously connected endoscopes are of the same type.

Abstract: An endoscope system includes: an endoscope having an image sensor configured to image an inside of a subject; a processor configured to perform predetermined image processing on a video signal that is imaged by the image sensor; a storage that is provided in the endoscope, the storage being configured to store compressed data obtained by compressing data volume of first non-compressed data that is used for correction of an image imaged by the image sensor; a restoring circuit configured to read the compressed data from the storage to restore the compressed data to the first non-compressed data when data is transferred from the endoscope to the processor; and an image correcting circuit that is provided in the endoscope, the image correcting circuit being configured to correct the image imaged by the image sensor by using the first non-compressed data restored by the restoring circuit.
