An operation procedure extrapolating system includes a history recording unit, a sort unit and an extrapolating unit. The history recording unit records history records of processes that at least one image processing apparatus is instructed to perform in a series of operation procedures. Each history record includes operator information, time information, content information and an object image. The sort unit sorts the history records into sets defined for individual operations, based on a comparison among the object images of the recorded history records. The extrapolating unit extrapolates operation procedures in at least one of the individual operations, based on the content information of the history records included in the set defined for the at least one of the individual operations and a sequence of the operator information of the history records included in the set defined for the at least one of the individual operations.
