摘要:
A moving image reproducer includes a generation section, a calculation section, a determination section, a correction section and a control section. The generation section generates an interpolation frame image interpolating between two adjacent frame images among a plurality of frame images. The calculation section sequentially calculates a progress level of a predetermined musical piece between the two adjacent frame images reproduced in synchronization with the predetermined musical piece. The determination section determines whether the progress level has varied along with a change in a tempo of the predetermined musical piece defined in the tempo information. The correction section corrects the progress level so as to reduce the variation in the progress level along with the change in the tempo if the progress level is determined to have varied. The control section controls the generation section to generate an interpolation frame image corresponding to the corrected progress level.
