AI Technical Summary
Technical Problem
Existing endoscope systems suffer from image disappearance issues when an abnormality occurs in the image processing unit, disrupting continuous display of endoscope images.
Method used
The system employs a dual processor configuration with a first processor device performing software-based first image processing and a second processor device performing hardware-based second image processing, along with an abnormality detection unit to switch between the two processing paths, ensuring continuous image display.
Benefits of technology
Prevents image loss and allows continuous display of endoscope images by switching to a secondary processing path when abnormalities occur in the primary image processing unit, enhancing system reliability.

Abstract
An endoscope system (1) comprises: a second processor device (3) that is connected to an endoscope (2) so as to be capable of communicating with the endoscope (2) and that acquires an image captured by the endoscope (2); a first processor device (4) that is connected to the second processor device (3) so as to be capable of communicating with the second processor device (3) and that acquires the captured image through the second processor device (3); and a display device (5) that displays the image. The first processor device (4) is provided with: a first image processing unit (422) that executes first image processing on the captured image by software processing and generates a first captured image; an abnormality detection unit (43) that detects the presence or absence of an abnormality in the first image processing unit (422); a second image processing unit (442) that executes second image processing on the captured image by a hardware configuration and generates a second captured image; and an image switching unit (443) that causes a display device (5) to display the first captured image or the second captured image as an endoscope image according to a result of detection by the abnormality detection unit (43).
