Abstract

Provided is a signal separation system including a rendering unit which receives a first and a second input signal and positions the first input signal according to rendering information.

Claims

1-38. -38. (canceled)

39. A signal processing system comprising a rendering section for receiving first and second input signals and rendering information for operating localization of said input signals, and localizing the first input signal based on said rendering information.

40. A signal processing system according to claim 39, wherein said rendering section localizes the second input signal at a position different from that of the first input signal.

41. A signal processing system according to claim 39, further comprising an enhancement processing section for receiving a signal in which a plurality of signal components are mixed, and enhancing a specific signal component in said signal to obtain said first input signal,

wherein said enhancement processing section improves a degree of separation of said specific signal component.

42. A signal processing system according to claim 41, wherein said enhancement processing section enhances a specific signal component other than said specific signal component to obtain said second input signal.

43. A signal processing system according to claim 39, wherein said first input signal is a signal in which a desired signal is enhanced.

44. A signal processing system according to claim 39, wherein said second input signal is a signal in which a signal other than a desired signal is enhanced.

45. A signal processing system according to claim 43, wherein said desired signal is voice.

46. A signal processing system according to claim 43, wherein the signal other than said desired signal is noise.

47. A signal processing system according to claims 43, further comprising a microphone for capturing a signal in which said desired signal and the signal other than said desired signal are mixed together.

48. A signal processing method comprising:

a receiving step of receiving first and second input signals and rendering information for operating localization of said input signals; and

a rendering step of localizing the first input signal based on said rendering information.

49. A signal processing method according to claim 48, wherein, in said rendering step, the second input signal is localized at a position different from that of the first input signal.

50. A signal processing method according to claim 48, further comprising:

a receiving step of receiving a signal in which a plurality of signal components are mixed; and

an enhancement processing step of enhancing a specific signal component in said signal to obtain said first input signal,

wherein said enhancement processing step improves a degree of separation of said specific signal component.

51. A signal processing method according to claim 50, wherein, in said enhancement processing step, a specific signal component other than said specific signal component is enhanced to obtain said second input signal.

52. A signal processing method according to claim 48, wherein said first input signal is a signal in which a desired signal is enhanced.

53. A signal processing method according to claim 48, wherein said second input signal is a signal in which a signal other than a desired signal is enhanced.

54. A signal processing method according to claim 52, wherein said desired signal is voice.

55. A signal processing method according to claim 52, wherein the signal other than said desired signal is noise.

56. A signal processing method according to claim 52, further comprising a signal capturing step of capturing a signal in which said desired signal and the signal other than said desired signal are mixed together.

57. A computer readable storage medium storing computer instructions for causing a computer to execute the instructions, said instructions causing said computer to implement a method comprising:

receiving processing of receiving first and second input signals and rendering information for operating localization of said input signals; and

rendering processing of localizing the first input signal based on said rendering information.
