Claim:
1. An endoscope system, comprising: an endoscope having an insertion portion that is to be inserted into a subject, an objective optical system provided in a distal end portion of the insertion portion, an image pickup portion that time-sequentially picks up optical images of the subject that are formed by the objective optical system to acquire a plurality of images, and a channel that is provided inside the insertion portion so as to have a channel opening in the distal end portion of the insertion portion; a laser probe that is inserted through the channel of the endoscope and that outputs a laser beam from a distal end portion towards the subject; an image analysis portion that detects an area of the laser probe with respect to each of a plurality of the images that are time-sequentially acquired; and a control portion that determines whether or not the laser probe protrudes from the channel opening based on detection results with respect to the area of the laser probe which are obtained by the image analysis portion for a plurality of the images that are time-sequentially consecutive, and permits the laser probe to output the laser beam only in a case where it is determined that the laser probe protrudes.
