    Abstract: The present technology relates to a device, a method, and a program for expanding a frequency band, which are capable of obtaining high-quality sound with a small processing amount. A low band extraction band-pass filter processing unit passes a predetermined band of a low band of an input signal and generates a low band sub band signal. A band-pass filter calculation circuit calculates band-pass filter coefficients of band-pass filters having sub bands of high bands as a pass band based on an estimate value of high band sub band power, and an addition unit obtains one filter coefficient by adding the band-pass filter coefficients. A poly-phase configuration level adjustment filter performs up-sampling and level adjustment by performing filtering on a flattened signal obtained from a low band sub band signal using the filter coefficient obtained by the addition unit, and generates a high band signal. An addition unit obtains an output signal by adding the high band signal to the low band signal. The present technology can be applied to a frequency band expanding device.

    Abstract: [Problem] To provide an information processing device, an information processing method, and a program that enable detection, with a higher degree of accuracy, of the bright spots and the pupils from the light reflected from the eyes.
    [Solution] An information processing device includes a light source that includes a first polarization filter; a sensor that includes a second polarization filter; and a control unit that processes images obtained by the sensor. The second polarization filter includes an orthogonal polarization filter having a direction perpendicular to the polarization direction of the first polarization filter, and includes a parallel polarization filter having a direction parallel to the polarization direction of the first polarization filter. The control unit detects the bright spot from a parallel polarization image obtained by the sensor, and detects the pupil from an orthogonal polarization image obtained by the sensor.

    Abstract: The present technology relates to an audio signal output device and a method, an encoding device and a method, a decoding device and a method, and a program for realizing audio reproduction with a more realistic feeling.In a case where an audio signal generated to be output as a sound from an ideal speaker that is a virtual speaker placed in an ideal position is input, the distance between the ideal speaker and a real reproduction speaker is determined. Gain adjustment is then performed on the audio signal with the gain corresponding to the determined distance, the audio signal subjected to the gain adjustment is reproduced by the reproduction speaker. Accordingly, even in a case where there is a difference in position between the ideal speaker and the reproduction speaker, audio reproduction with a more realistic feeling can be realized. The present technology can be applied to reproduction devices.
