MARKER DETECTING APPARATUS AND RADIO-CONTROLLED TIMEPIECE |
摘要 |
A marker detecting apparatus includes: a signal input section where a time code signal is inputted; a level detecting section detecting a signal level of a pulse signal of the time code signal at points in a marker characteristic interval to detect a match between the pulse signal and an ideal marker pulse signal in the signal level; a first calculating section calculating a number of the detected matches so as to obtain a value thereof, and correlating the obtained value with a pulse position of the pulse signal, the pulse position being a same in any of frames of the time code signal; a second calculating section adding up the obtained values correlated with the pulse position in the frames; and a marker determining section determining at which pulse position in the frames a marker pulse signal is disposed, based on the added-up value.
