Abstract: For the purpose of acquiring an image in which distortion is suppressed even if the moving speed of a viewing-field region is increased, a scanning endoscope apparatus (1) is provided with: a scanner that has an optical fiber, which guides light coming from a light source (2) and makes the light exit from an exit end thereof, and a drive portion, which displaces the exit end in a direction that intersects an optical axis, and that scans the light that is made to exit from the exit end over an observation subject; a light detection portion (6) that receives return light coming from the observation subject generated by scanning the light by the scanner; a speed detection portion (7) that detects the moving speed of the scanner; and a control portion (9) that controls the drive portion so as to decrease a length of a scanning track of the light on the observation subject with an increase in the moving speed detected by the speed detection portion (7).
