DEVICE FOR ESTIMATING CHANGES IN TARGET OBJECTS

摘要

Disclosed is a device for estimating changes in target objects that can be used as preferred means of estimating changes over time in objects. A first estimation means estimates the change in the object after the actual change occurs in the object, and a second estimation means estimates the change in the object before the actual change occurs in the object. When a change occurs in the object, a correction means calculates the change in the object by correcting either of the first or second correction means based on the other correction means. This makes it possible to improve the accuracy of the estimation of changes in the target objects.
