Problems solved by technology

Due to the signal degradation caused by these various factors, there is a problem that the synchronization signal superimposed on the video signal from the CCD may not be detected in the video processor.
If the synchronization signal cannot be detected in the video processor, the subsequent video processing cannot be performed, and the observed image of the endoscope cannot be displayed.

Abstract

An endoscopic image processing apparatus includes an endoscope information reading section that reads endoscope information that is information relating to an endoscope from the endoscope, a synchronizing signal detecting section that is given an image pickup signal that includes a synchronizing signal outputted by an image pickup device provided in the endoscope from the endoscope, performs detection processing of the synchronizing signal, outputs the detected synchronizing signal when the synchronizing signal can be detected, and generates and outputs a synchronizing signal based on the endoscope information read by the endoscope information reading section when the synchronizing signal cannot be detected, and an image signal generating section that generates an image signal based on the synchronizing signal outputted from the synchronizing signal detecting section and the image pickup signal outputted from the image pickup device of the endoscope.

Description

technical field [0001] The present invention relates to an endoscope image processing device and an endoscope system for processing endoscope images from an imaging device. Background technique [0002] In recent years, endoscopes have been widely used in the medical field for diagnosis, treatment using treatment instruments, and the like. An electronic endoscope device in which an imaging element such as a charge-coupled device (CCD) is installed at the tip of an endoscope insertion portion, and an observation image captured by the CCD is displayed on a television monitor by a video processor is widely used. [0003] A driving circuit is arranged in the video processor, and the driving signal from the driving circuit is transmitted to the CCD at the front end of the endoscope to drive the CCD. In such a drive circuit, a synchronous signal (VD) is superimposed on the drive signal and supplied to the CCD. The CCD outputs the video signal of each pixel in synchronization wit...
