Abstract
A refrigerator and a control method for the same are disclosed. A refrigerator includes a storage compartment, a drawer movably provided in the storage compartment and provided with a marker, a camera that photographs inside the drawer from outside the drawer, and a controller that senses a position of the marker in photographs taken through the camera at time intervals, and that determines state information about the drawer based on a change in position of the marker in the photographs. A method includes recognizing closing of the drawer by sensing a start of opening of the drawer; acquiring an image of the drawer interior using the camera; processing the image to recognize the marker from the image; tracing a movement of the marker; acquiring a final image of the drawer interior using the camera when closing of the drawer begins; and displaying the final image.
