Patent ID: 8761567

Claim:
A moving image reproducer comprising: a non-transitory storage section which stores a plurality of frame images; and a processor which is operable as: a calculation section which sequentially calculates a progress level of a predetermined musical piece, which is provided with tempo information, between two adjacent frame images among the plurality of frame images reproduced in synchronization with the predetermined musical piece; a generation section which sequentially generates, based on the progress level of the predetermined musical piece between the two adjacent frame images calculated by the calculation section, interpolation frame images each of which interpolates between two adjacent frame images among the plurality of frame images; a determination section which determines whether the progress level has varied along with a change in a tempo of the predetermined musical piece defined in the tempo information; and a control section which, when the determination section determines that the progress level has varied along with the change in the tempo, controls the generation section to newly generate an interpolation frame image so that the newly generated interpolation frame image corresponds to the progress level having varied along with the change in the tempo.
