摘要： Disclosed herein is a washing machine capable of identifying whether laundry of an inner tub includes waterproof clothing. The washing machine includes a cabinet provided with an opening at an upper portion thereof, an outer tub provided in the cabinet, an inner tub provided in the outer tub, a motor configured to rotate the inner tub, a camera configured to capture an image of an inside of the inner tub, and a controller configured to control the motor to increase a rotational speed of the inner tub to a first rotational speed during spinning. The controller is configured to control the motor to set the rotational speed of the inner tub to a second rotational speed, which is less than the first rotational speed, based on the image of the inside of the inner tub captured by the camera during the spinning.
