PROBLEM TO BE SOLVED: To provide an electronic endoscope apparatus capable of outputting a moving image with intensified unevenness.SOLUTION: The electronic endoscope apparatus includes: an electronic endoscope having an imaging means for capturing the image of a subject at the distal end to output the image output from the imaging means as an image signal a monitor and an electronic endoscopic processor to generate a video signal which can be displayed in the monitor by processing the image signal. The electronic endoscope apparatus also includes an illuminating means for emitting a plurality of illumination beams from the distal end of the electronic endoscope. The imaging means is disposed at the center of the distal end as the distal end of the electronic endoscope is seen from the front, and a plurality of illumination beam outlets are disposed on the circumference around the imaging means at uniform angles. The plurality of illumination beams are emitted from the outlets at a prescribed emission angle. Illumination regions illuminated with the plurality of illumination beams respectively include imaging regions to be captured by the imaging means. The plurality of illumination beams are switched to one after another based on a field period or frame period of the imaging means, and one of the plurality of illumination beams is emitted.COPYRIGHT: (C)2012,JPO&INPIT【課題】凹凸強調された動画像を出力可能な電子内視鏡装置を提供する。【解決手段】先端部に被写体を撮像する撮像手段を有し、撮像手段から出力される画像を映像信号として出力する電子内視鏡と、モニタと、映像信号を処理してモニタに表示可能なビデオ信号を生成する電子内視鏡用プロセッサとを備えた電子内視鏡装置が、電子内視鏡の先端部から複数の照明光を出射する照明手段を有し、撮像手段は、電子内視鏡の先端部を前面から見た場合に該先端部の中央に配置され、複数の照明光の出射口は撮像手段を中心とした円周上に均等な角度で配置され、複数の照明光は所定の出射角度で前記出射口から出射され、複数の照明光によって照明される照明領域は、それぞれ撮像手段によって撮像される撮像領域を含み、複数の照明光は、撮像手段のフィールド周期又はフレーム周期に基づいて順次切り換えられ、複数の照明光のうちの1つが出射される。【選択図】 図3
