Time information acquiring apparatus and radio controlled timepiece

摘要

A time information acquiring apparatus for acquiring time information from a time code signal included in a standard radio waver including: a pulse measuring section which detects a matching level of an individual pulse signal constituting the time code signal to a predetermined code value; a grouping section which groups pulse signals into one group; a code string estimating section which estimates a code string having a possibility of emerging in a portion of the group in a frame of the time code signal; a code string determining section which determines a probability that the code string indicated by the grouped pulse signals corresponds to the estimated code string based on the matching level; and a time information generating section which generates the time information based on the code string for which the code string determining section determines that the probability is high.
