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.

Abstract: A signal processing device processes a signal sent from an imaging device detachably attached to the signal processing device and includes: a signal processing unit configured to rewrite processing contents in accordance with a configuration; configuration memories having different capabilities and configured to store pieces of configuration data corresponding to contents of image processes that are performed in accordance with imaging sensors held by the imaging devices; a configuration controller configured to perform control to subject the signal processing unit to reconfiguration using the configuration data that depends on the imaging sensor of the imaging device attached to the signal processing device among the configuration data; a priority setting unit configured to set priority for each configuration data based on a predetermined condition; and a rewrite controller configured to rewrite the configuration data in the configuration memories based on the priority set by the priority setting unit.
