Abstract

An information processing apparatus of the present invention is provided with a musical composition storing unit for storing musical composition data, a reproducing unit for reproducing the musical composition, a meta information storing unit for storing meta information including a position of the musical data and an amount of characteristic indicating characteristics of the musical composition data at the position, an amount of characteristic obtaining unit for obtaining the amount of characteristic at a reproduction position of the musical composition data reproduced by the reproducing unit at predetermined timing, and a blink control unit for controlling a blink of an light emitting unit for emitting light according to the amount of characteristic obtained by the amount of characteristic obtaining unit.

Claims

1. An information processing apparatus, comprising:

a musical composition storing unit for storing musical composition data;

a reproducing unit for reproducing the musical composition data;

a meta information storing unit for storing meta information including a position of the musical composition data and an amount of characteristic indicating characteristics of the musical composition data at the position;

an amount of characteristic obtaining unit for obtaining the amount of characteristic at a reproduction position of the musical composition data reproduced by the reproducing unit at predetermined timing; and

a blink control unit for controlling a blink of a light emitting unit for emitting light according to the amount of characteristic obtained by the amount of characteristic obtaining unit.

2. The information processing apparatus according to claim 1,

wherein the meta information includes information regarding a beat being associated with the position of the musical composition data, and

the amount of characteristic obtaining unit obtains the amount of characteristic of the musical composition data at timing of the beat.

3. An information processing apparatus, comprising:

a musical composition storing unit for storing musical composition data;

a reproducing unit for reproducing the musical composition data;

a meta information obtaining unit for obtaining meta information in which information regarding reproduced musical composition data being the musical composition data being reproduced by the reproducing unit is described;

a judging unit for judging change in an amount of characteristic indicating characteristics of the reproduced musical composition data at predetermined timing based on the meta information obtained by the meta information obtaining unit; and

a blink control unit for controlling a blink of a light emitting unit for emitting light when the amount of characteristic of the reproduced musical composition data changes.

4. The information processing apparatus according to claim 3, further comprising:

a blink information storing unit for associating a classification pattern to classify the musical composition data with a predetermined condition and a blink pattern to blink the light emitting unit with each other to store; and

a blink pattern obtaining unit for obtaining the blink pattern;

wherein the blink control unit controls the blink of the light emitting unit based on the blink pattern of the reproduced musical composition data obtained by the blink pattern obtaining unit.

5. The information processing apparatus according to claim 4,

wherein the blink pattern is determined according to a tune of the musical composition data.

6. The information processing apparatus according to claim 5,

wherein the blink control unit does not blink the light emitting unit in a silent part present in the musical composition data being reproduced by the reproducing unit.

7. The information processing apparatus according to claim 3, further comprising:

a blink judging unit for judging whether to allow the light emitting unit to emit light;

wherein the blink judging unit judges when the amount of characteristic of the reproduced musical composition data changes, and

the control unit controls the blink of the light emitting unit only when it is judged to allow the light emitting unit to emit light by the blink judging unit.

8. The information processing apparatus according to claim 3, further comprising:

a musical composition analyzing unit for analyzing the musical composition data to obtain information regarding the musical composition data;

wherein the musical composition analyzing unit generates the meta information in which the information regarding the musical composition data is described.

9. The information processing apparatus according to claim 8,

wherein the blink control unit allows the light emitting unit to emit light based on a predetermined blink pattern set in advance when the musical composition data is not analyzed by the musical composition analyzing unit.

10. The information processing apparatus according to claim 8,

wherein the musical composition analyzing unit stores the generated meta information in the musical composition storing unit together with the musical composition data.

11. The information processing apparatus according to claim 8, further comprising:

a meta information storing unit for associating the meta information in which the information regarding the musical composition data is described and the musical composition data with each other to store;

wherein the musical composition analyzing unit records the generated meta information in the meta information storing unit, aside from the musical composition data.

12. The information processing apparatus according to claim 3, further comprising:

a display unit for displaying an operating screen for operating the reproducing unit;

wherein a color tone of the operating screen is changed according to a classification pattern of the reproduced musical composition data.

13. A light emission control method, comprising the steps of:

storing musical composition data;

reproducing the musical composition data;

recording meta information including a position of the musical composition data and an amount of characteristic indicating characteristics of the musical composition data at the position in a meta information storing unit;

obtaining the amount of characteristic at a reproduction position of the musical composition data reproduced at predetermined timing; and

controlling a blink of a light emitting unit for emitting light according to the obtained amount of characteristic.

14. A computer program for allowing a computer to operate as:

storing means for storing musical composition data;

reproducing means for reproducing the musical composition data;

meta information recording means for recording meta information including a position of the musical composition data and an amount of characteristic indicating characteristics of the musical composition data at the position in a meta information storing unit;

amount of characteristic obtaining means for obtaining the amount of characteristic at a reproduction position of the musical composition data reproduced by the reproducing means at predetermined timing; and

blink control means for controlling a blink of a light emitting unit for emitting light according to the amount of characteristic obtained by the amount of characteristic obtaining means.
