Image processing device for endoscope that reconfigures image processing circuit based on disconnection time
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.
1. An image processing device comprising:
an image processing circuit configured to process image data obtained from an endoscope, the image processing circuit being configurable according to an application of the endoscope; and
at least one control circuit configured to:
detect a connection state of the endoscope,
measure, based on a detection result of the connection state, a disconnection time from when the endoscope is disconnected until the endoscope is reconnected,
determine, when the disconnection time is shorter than a predetermined time, that a currently connected endoscope and a previously connected endoscope are configured for a same application type,
reconfigure the image processing circuit according to the type of the currently connected endoscope when it is determined that the currently connected endoscope and the previously connected endoscope are not configured for the same application type, and
not reconfigure the image processing circuit when it is determined that the currently connected endoscope and the previously connected endoscope are configured for the same application type.
2. The image processing device according to claim 1 , further comprising a storage circuit configured to store the type of the previously connected endoscope.
3. The image processing device according to claim 2 , wherein the at least one control circuit is configured to obtain, when it is determined that the currently connected endoscope and the previously connected endoscope are not configured for the same application type, information on the application type of the endoscope stored in the storage circuit.
4. The image processing device according to claim 1 , wherein the image processing circuit is configured to change a circuit configuration of the image processing circuit to reconfigure the image processing circuit.
5. The image processing device according to claim 1 , wherein the image processing circuit is configured to rewrite software of the image processing circuit to reconfigure the image processing circuit.
6. The image processing device according to claim 1 , further comprising an image output circuit having a function to output the image data output from the image processing circuit to the outside of the image processing device, the image output circuit being configured to stop output of the image data to the outside of the image processing device when it is detected that the control circuit and the endoscope are disconnected.
7. The image processing device according to claim 1 , wherein the currently connected endoscope is the same as the previously connected endoscope.
