PROBLEM TO BE SOLVED: To provide an endoscope apparatus, which has an insertion section inserting into a subject in use and is capable of performing appropriate noise suppression processing for noises including noises due to the brightness of images captured by an imaging element and noises entering the signal transmission path.SOLUTION: The endoscope apparatus transmits a digital signal including an imaging signal, corresponding to an image of a subject captured by an imaging element mounted in a distal end part inserting into a subject, to a main body part, comprising an image processing unit for applying an imaging process to the imaging signal, by means of a signal transmission path provided in a flexible part which guides the distal end part into the subject. The endoscope apparatus comprises: data error rate detecting means for detecting, based on the digital signal transmitted through the signal transmission path, a data error rate during transmission of the digital signal and a noise suppression processing unit which determines, based on the data error rate, a noise suppression intensity for noise suppression processing and applies, with the determined noise suppression intensity, a noise suppression process to the imaging signal prior to image processing.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】被検物内に挿入部を挿入して使用する内視鏡装置において、撮像素子によって撮像した画像の明るさに起因するノイズと信号伝送路に進入するノイズとを含めて、適切なノイズ抑制の処理を行うことができる内視鏡装置を提供する。【解決手段】被検物内に挿入される先端部に具備した撮像素子が撮影した被写体の画像に応じた撮像信号を含むデジタル信号を、撮像信号に対して画像処理を施す画像処理部を具備した本体部に、先端部を被検物内に導く軟性部に具備した信号伝送路によって伝送する内視鏡装置であって、信号伝送路によって伝送されたデジタル信号に基づいて、該デジタル信号を伝送する際のデータ誤り率を検知するデータ誤り率検知手段と、データ誤り率に基づいてノイズ抑制処理を施す際のノイズ抑制強度を決定し、決定したノイズ抑制強度で、画像処理を施す前の撮像信号に対してノイズ抑制処理を施すノイズ抑制処理部と、を備える。【選択図】図1
