Information processor, information processing system, and information processing method

An information processing system, comprising:

• a wearable device that includes a microphone, wherein
• the wearable device is wearable on an ear in a wearable state of the wearable device,
• the microphone is at a distance from an ear hole of the ear based on the wearable state of the wearable device, and
• the wearable device is configured to:
• detect a first signal by the microphone;
• and
• output the first signal;
• a vehicle mounted unit configured to acquire a second signal indicating a noise from a noise source;
• and
• a first unit that comprises:
• an acquisition section configured to:
• acquire the first signal from the wearable device;
• acquire the second signal from the vehicle mounted unit;
• a digital signal processor (DSP) configured to receive first noise cancellation capability information of the vehicle mounted unit from the vehicle mounted unit based on a noise cancellation function of the vehicle mounted unit;
• and
• an operation mode control section configured to select a first operation mode of a plurality of operation modes of the DSP based on the received first noise cancellation capability information, wherein
• each operation mode of the plurality of operation modes corresponds to a coordinated operation of the DSP with the vehicle mounted unit,
• the coordinated operation of the DSP with the vehicle mounted unit in the first operation mode is different from the coordinated operation of the DSP with the vehicle mounted unit in a second operation mode of the plurality of operation modes,
• the coordinated operation of the DSP with the vehicle mounted unit in the first operation mode is based on a frequency band shared between the microphone and the vehicle mounted unit, and
• the DSP is further configured to:
• transmit second noise cancellation capability information of the wearable device to the vehicle mounted unit based on the noise cancellation function of the vehicle mounted unit, wherein the transmitted second noise cancellation capability information indicates the first operation mode;
• and
• generate a noise cancellation signal, for the noise, based on the acquired first signal, the acquired second signal, and the first operation mode.
