PROBLEM TO BE SOLVED: To provide an endoscope apparatus quickly displaying images picked up in the past at a display part.SOLUTION: When a still image X displayed at the display part 400 is not the latest among the still images stored in a first large capacity storage device 305, a system controller 301 reads x-(n/2)-1 sheets of the still images captured before the still image X and x-(n/2) sheets of the still images captured more recently than the still image X from the first large capacity storage device 305, and stores them into an image memory 302. At the time, a system controller 301 erases the still images not included in the still images to be newly stored from the image memory 302, and reads only the still images not stored in the image memory 302 from the first large capacity storage device 305.
