1. A video processor comprising:
- a video signal processing unit that processes a video signal input from an endoscope;
a distribution unit that distributes hardware resources and software resources related to video signal processing performed by the video signal processing unit to a first partition and a second partition;
a first assignment unit that assigns minimal processing from among the video signal processing to the resources distributed to the first partition;
a second assignment unit that assigns processing from among the video signal processing that is other than the minimal processing to the resources distributed to the second partition;
a monitoring unit that monitors anomalies in the resources distributed to the first partition and the second partition; and
a resetting unit that only resets resources distributed to a partition in which an anomaly has been detected by the monitoring unit, whereinwhen an anomaly in a certain resource distributed to the second partition has been detected by the monitoring performed by the monitoring unit, the video signal processing unit only performs the minimal processing from among the video signal processing that has been assigned to the resources distributed to the first partition until the certain resource returns to normal by the resetting unit performing the resetting.

Abstract
A video processor distributes hardware resources and software resources related to video signal processing performed by a video signal processing unit to a first partition and a second partition, assigns minimal processing from among the video signal processing to the resources distributed to the first partition, assigns processing from among the video signal processing that is other than the minimal processing to the resources distributed to the second partition, monitors anomalies in the resources distributed to the first partition and the second partition, and only resets resources distributed to a partition in which an anomaly has been detected by the monitoring.

4. A video processor for use with an endoscope, the video processor comprising:
a processor programmed to; process a video signal input received from the endoscope; distribute hardware resources and software resources to a first partition and a second partition for processing of the video signal input; assign minimal processing from among the video signal processing to the resources distributed to the first partition; assign processing from among the video signal processing that is other than the minimal processing to the resources distributed to the second partition; detect whether anomalies are present in the resources distributed to the first partition and the second partition; reset resources distributed to the first partition or the second partition only when an anomaly has been detected in the respective first partition or the second partition; and when an anomaly in a certain resource distributed to the second partition has been detected, the minimal processing from among the video signal processing that has been assigned to the resources distributed to the first partition is only performed until the certain resource returns to normal in response to the resetting of resources in the second partition. - View Dependent Claims (5, 6)
