Title: Specific-condition-section detection apparatus and method of detecting specific condition section

Abstract: A specific-condition-section detection apparatus configured to detect a specific condition section in a data signal having a signal level that continues to be closer to a predetermined signal level than a reference level includes a signal correcting unit configured to correct the data signal so that a segment of the data signal is corrected to a level closer to the predetermined signal level than the reference level for a predetermined amount of time starting from the point where the signal level of the data signal changes from a level closer to the predetermined signal level than the reference level to a level further away from the predetermined signal level than the reference level, and a determining unit configured to determine whether the level of the corrected data signal is closer to the predetermined signal level than the reference level.
