PROBLEM TO BE SOLVED: To provide an endoscope apparatus to be used with an insertion part being inserted into a subject, the endoscope apparatus allowing a drive signal with no degradation in waveforms to be input into an image pickup device provided in the tip part located at the distal end of the insertion part.SOLUTION: The endoscope apparatus comprises: an insertion part which has an image pickup device at the distal end for outputting pixel signals according to a captured image and transfers a drive signal for driving the image pickup device and a body part which includes a drive signal generation unit which generates the drive signal. The body part generates a control signal which is iterated for each horizontal period comprising a horizontal driving period during which signals stored in the pixels of the image held by the image pickup device are sequentially driven and read out, and a horizontal blanking period during which the signals stored in the pixels are not read out. The endoscope apparatus also comprises a horizontal drive signal generation unit which generates a horizontal drive signal for sequentially driving and reading out the signals stored in the pixels in the image pickup device, on the basis of the control signal.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,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、挿入部の先端に位置する先端部内に備えた撮像素子に波形の劣化のない駆動信号を入力することができる内視鏡装置を提供する。【解決手段】撮影した映像に応じた画素信号を出力する撮像素子を先端に具備し、撮像素子を駆動するための駆動信号を伝送する挿入部と、駆動信号を生成する駆動信号発生部を具備した本体部と、を有する内視鏡装置であって、本体部は、撮像素子が有する画素に蓄積された信号を順次駆動して読み出す期間である水平駆動期間と、画素に蓄積された信号の読み出しをしない期間である水平ブランキング期間とを含んだ1つの水平期間に対応し、1水平期間ごとに反復する制御信号を生成し、当該内視鏡装置は、制御信号に基づいて、撮像素子内の画素に蓄積された信号を順次駆動して読み出すための水平駆動信号を生成する水平駆動信号生成部、を備える。【選択図】図2
