PROBLEM TO BE SOLVED: To provide an optical scanning endoscope apparatus capable of suppressing the occurrence of false color and color shift.SOLUTION: An optical scanning endoscope apparatus 10 includes a light emission timing control part 32 for controlling the light emission timing of a light source for selectively emitting light having a plurality of different wavelengths, scanning means for repeatedly scanning the light from the light source on an object, a light detection part 35 for detecting light obtained from the object by light irradiation and converting the light into an electric signal, and a signal processing part 37 for generating an image signal on the basis of the electric signal from the light detection part. The light emission timing control part switches wavelengths of the light from the light source, during scanning, in a light emission order different from a light emission order of the preceding scanning.COPYRIGHT: (C)2015,JPO&INPIT【課題】偽色と色ずれの発生を抑制できる、光走査型内視鏡装置を提供する。【解決手段】光走査型内視鏡装置10は、複数の異なる波長の光を選択的に射出する光源の発光タイミングを制御する発光タイミング制御部32と、光源からの光を対象物上で繰り返し走査させる走査手段と、光の照射により対象物から得られる光を検出して電気信号に変換する光検出部35と、光検出部からの電気信号に基づいて画像信号を生成する信号処理部37とを備え、発光タイミング制御部は、走査中に、光源からの光の波長を、前回の走査の発光順序とは異なる発光順序で切り替えることを特徴とする。【選択図】図1
