Abstract:
Disclosed herein is a time code processing apparatus including a time code reading section configured to read each of the first time code values; a phase detection section configured to detect a phase in a sequence of the pulldown process; and a time code generation section configured to use the first time code value as the second time code value when both the phase detected by the phase detection section and the first time code value obtained by the time code reading section have changed, and generate the second time code value while performing an interpolation based on the first time code value when at least one of the phase detected by the phase detection section and the first time code value obtained by the time code reading section has not changed.
