Abstract
Method and apparatus for detecting change of an object state from an initial state where the object is displayed in a plurality of sequential images. The system involves comparing a measure over a predetermined portion of each of the images corresponding to an object's initial state with a reference value of the measure computed when the object is in the initial state to generate a comparison value for each of the images and then generating a signal indicating that the object state has changed when a predetermined number of the comparison values generated for each of the images do not meet a predetermined criterion.
