A refrigerator includes a dispenser having a dispenser well, a control for regulating a product dispensing operation, and a select fill sensor system for automatically initiating and terminating the dispensing operation. An optical sensing system includes a camera within the dispenser well in communication with a controller for sensing the fill rate of a container within the dispenser well. The dispensing rate of product is adjusted depending on the product fill rate of the container such that optimum fill rates are obtained without overflow or spilling events. In this manner, a hands-free dispenser is provided that can be utilized regardless of the shape or size of container utilized.
