Abstract

The present invention is designed so that, even when a CG model moves with a tempo, it is possible to realize natural movement. The device according to one aspect of the present invention has a control section that exerts control so that specific data, which corresponds to a case where a predetermined parameter has a specific value, is generated using a plurality of pieces of data corresponding to respective cases where the predetermined parameter has different values, and a playback section that reproduces a predetermined computer graphics (CG) model based on the specific data.

First claim

The invention claimed is:

1. A device comprising:
a processor that generates specific data, which corresponds to a case where a predetermined parameter has a specific value, using a plurality of pieces of data corresponding to respective cases where the predetermined parameter has different values; and
wherein the processor reproduces a predetermined computer graphics (CG) model based on the specific data,
wherein the predetermined parameter is at least one from among a tempo (Beats Per Minute (BPM)) with which a motion of the predetermined CG model is indicated and a parameter that indicates a characteristic of motion of the predetermined CG model, and
wherein the plurality of pieces of data are motion data of the predetermined CG model, and include time series information that designates the coordinates of components of the predetermined CG model in chronological order in units of beats.

2. The device according to claim 1 , wherein the processor generates the specific data, using, among the plurality of pieces of data, data that is generated so that, in first data, which corresponds to a case the predetermined parameter has a first value, the first value matches the specific value, and data that is generated so that, in second data, which corresponds to a case the predetermined parameter has a second value, the second value matches the specific value.

3. The device according to claim 1 , wherein the plurality of pieces of data are included in channels of the same data structure conforming to SMF (standard MIDI File) format.

4. The device according to claim 1 , wherein the predetermined parameter is included in a signal defined in SMF (Standard MIDI File) format or in an OSC (Open Sound Control) message.

5. The device according to claim 1 , wherein at least one from among the number of the plurality of pieces of data and the value of the predetermined parameter corresponding to each data varies over time.

6. The device according to claim 1 , wherein, when the specific value varies from a third value to a fourth value, and an absolute value of the difference between the third value and the fourth value is greater than or equal to a predetermined threshold, the processor generates the specific data, in a predetermined period from the timing the specific value varies, based on the assumption that the specific value is between the third value and the fourth value, and
wherein the specific data for the specific value of the third value gradually changes to the specific data for the specific value of the fourth value for over the predetermined period.

7. The device according to claim 1 , wherein the predetermined parameter is at least one from among a parameter to indicate a magnitude of motion, a parameter to indicate vibes of motion, and a parameter to indicate a quality of motion that includes at least one from among manly motion and feminine motion.

8. The device according to claim 1 , wherein the plurality of pieces of data are dance motion data, and
wherein the plurality of pieces of data of at least one from among the components of the predetermined CG model are a same coordinate at a timing at which a leg touches a ground or a timing at which the motion stops.

9. The device according to claim 1 , wherein the plurality of pieces of data includes a position information of the predetermined CG model for a predetermined frame cycle,
wherein the predetermined frame cycle is calculated by multiplying a duration of beats by a number of frames per unit time.

10. A non-transitory computer readable storage medium having stored thereon instructions comprising executable code, which when executed by a processor, cause the processor to:
generate specific data, which corresponds to a case where a predetermined parameter has a specific value, using a plurality of pieces of data corresponding to respective cases where the predetermined parameter has different values; and
reproduce a predetermined computer graphics (CG) model based on the specific data,
wherein the predetermined parameter is at least one from among a tempo (Beats Per Minute (BPM)) with which a motion of the predetermined CG model is indicated and a parameter that indicates a characteristic of motion of the predetermined CG model, and
wherein the plurality of pieces of data are motion data of the predetermined CG model, and include time series information that designates the coordinates of components of the predetermined CG model in chronological order in units of beats.

11. The storage medium according to claim 10 , wherein, in the control step, the specific data is generated, using, among the plurality of pieces of data, data that is generated so that, in first data, which corresponds to a case the predetermined parameter has a first value, the first value matches the specific value, and data that is generated so that, in second data, which corresponds to a case the predetermined parameter has a second value, the second value matches the specific value.

12. The storage medium according to claim 10 , wherein the plurality of pieces of data are included in channels of the same data structure conforming to SMF (standard MIDI File) format.

13. The storage medium according to claim 10 , wherein the predetermined parameter is at least one from among a parameter to indicate a magnitude of motion, a parameter to indicate vibes of motion, and a parameter to indicate a quality of motion that includes at least one from among manly motion and feminine motion.

14. The storage medium according to claim 10 , wherein the plurality of pieces of data are dance motion data, and
wherein the plurality of pieces of data of at least one from among the components of the predetermined CG model are a same coordinate at a timing at which a leg touches a ground or a timing at which the motion stops.

15. The storage medium according to claim 10 , wherein the plurality of pieces of data includes a position information of the predetermined CG model for a predetermined frame cycle,
wherein the predetermined frame cycle is calculated by multiplying a duration of beats by a number of frames per unit time.

16. An information processing method, comprising the steps of:
generating specific data, which corresponds to a case where a predetermined parameter has a specific value, using a plurality of pieces of data corresponding to respective cases where the predetermined parameter has different values; and
reproducing a predetermined computer graphics (CG) model based on the specific data,
wherein the predetermined parameter is at least one from among a tempo (Beats Per Minute (BPM)) with which a motion of the predetermined CG model is indicated and a parameter that indicates a characteristic of motion of the predetermined CG model, and
wherein the plurality of pieces of data are motion data of the predetermined CG model, and include time series information that designates the coordinates of components of the predetermined CG model in chronological order in units of beats.

17. The method according to claim 16 , wherein the predetermined parameter is at least one from among a parameter to indicate a magnitude of motion, a parameter to indicate vibes of motion, and a parameter to indicate a quality of motion that includes at least one from among manly motion and feminine motion.
