Abstract

There is provided a signal processing system including a first detection section which detects, from outside a body cavity, first audio signals of a prescribed part inside the body cavity, a second detection section which detects, from inside the body cavity, second audio signals of the prescribed part inside the body cavity, and a generation section which generates third audio signals based on the first audio signals and the second audio signals.

Claims

1. A signal processing system comprising:

a first detection section which detects, from outside a body cavity, first audio signals of a prescribed part inside the body cavity;

a second detection section which detects, from inside the body cavity, second audio signals of the prescribed part inside the body cavity; and

a generation section which generates third audio signals based on the first audio signals and the second audio signals.

2. The signal processing system according to claim 1,

wherein the second detection section is a capsule type medical apparatus introduced into the body cavity.

3. The signal processing system according to claim 1,

wherein the second detection section is an endoscope type medical apparatus introduced into the body cavity.

4. The signal processing system according to claim 1, further comprising:

a plurality of the second detection sections.

5. The signal processing system according to claim 1,

wherein the generation section generates the third audio signals upon correcting a time difference between the first audio signals and the second audio signals based on a distance between the first detection section and the prescribed part, and a distance between the second detection section and the prescribed part.

6. The signal processing system according to claim 5,

wherein the generation section generates the third audio signals by separating audio signals originating at the prescribed part from the first audio signals and the second audio signals in which the time difference is corrected.

7. The signal processing system according to claim 1, further comprising:

an encoder section which encodes the third audio signals; and

a transmission section which transmits the third audio signals encoded by the encoder section to an external apparatus.

8. The signal processing system according to claim 7, further comprising:

a reception section which receives, from the external apparatus, third audio signals previously received and accumulated by the external apparatus in accordance with a position of the first detection section.

9. The signal processing system according to claim 8, further comprising:

a reproduction section which reproduces the third audio signals generated by the generation section or the third audio signals received by the reception section.

10. A signal processing apparatus comprising:

a first detection section which detects, from outside a body cavity, first audio signals of a prescribed part inside the body cavity; and

a generation section which generates third audio signals based on the first audio signals, and second audio signals of the prescribed part inside the body cavity detected by a second detection section which detects, from inside the body cavity, the second audio signals.

11. The signal processing apparatus according to claim 10,

wherein the signal processing apparatus is an electronic auscultation apparatus, and

wherein the second detection section is a capsule type medical apparatus introduced into the body cavity.

12. The signal processing apparatus according to claim 10,

wherein the signal processing apparatus is an electronic auscultation apparatus, and

wherein the second detection section is an endoscope type medical apparatus introduced into the body cavity.

13. The signal processing apparatus according to claim 10,

wherein the generation section generates the third audio signals based on the first audio signals and a plurality of the second audio signals detected by a plurality of the second detection sections.

14. The signal processing apparatus according to claim 10,

wherein the generation section generates the third audio signals upon correcting a time difference between the first audio signals and the second audio signals based on a distance between the first detection section and the prescribed part, and a distance between the second detection section and the prescribed part.

15. A non-transitory computer-readable storage medium having a program stored thereon, the program causing a computer to execute:

detecting, from outside a body cavity, first audio signals of a prescribed part inside the body cavity;

detecting, from inside the body cavity, second audio signals of the prescribed part inside the body cavity; and

generating third audio signals based on the first audio signals and the second audio signals.

16. A non-transitory computer-readable storage medium having a program stored thereon, the program causing a computer to execute:

detecting, from outside a body cavity, first audio signals of a prescribed part inside the body cavity; and

generating third audio signals based on the first audio signals, and second audio signals of the prescribed part inside the body cavity detected from inside the body cavity.
