Ice level and quality sensing system employing digital imaging

摘要

A refrigerator includes a sensing system for detecting a level and quality of ice cubes in an ice cube storage bin. The sensing system employs a digital image capture device that is coupled to a digital image analyzing system which scans digital images of the ice cube storage bin captured by the digital image capture device to determine a level of ice cubes in the ice cube storage bin. Digital images of the ice cubes are contrasted against a reference image which provides a point of comparison for determining the level of ice cubes in the ice cube storage bin and controlling ice production cycles of the ice maker. The sensing system also analyzes edge portions of the ice cubes to determine ice cube quality.
