    Abstract: An active noise reduction device includes a standard signal generator, an adaptive filter unit, a control sound output unit, and an error signal detector. The adaptive filter unit includes a control signal generator, a filter coefficient update unit, and a step size setting unit. The control signal generator multiplies a standard signal by a filter coefficient to generate a control signal. Based on a reference signal and an error signal, the filter coefficient update unit updates the filter coefficient so as to minimize the error signal. The step size determiner sets a step size parameter indicating an update amount of the filter coefficient. The filter coefficient update unit sets a step size adjustment coefficient for adjusting the step size parameter based on an audio information feature amount and a change of the control signal.

    Abstract: A fake engine sound control device includes an environment information acquisition unit, a vehicle speed acquisition unit, an engine speed acquisition unit, a fake engine sound generator, and a fake engine sound controller. The environment information acquisition unit acquires environment information. The vehicle speed acquisition unit acquires vehicle speed information. The engine speed acquisition unit acquires rotation speed information. The fake engine sound generator generates a fake engine sound. The fake engine sound controller determines, based on the environment information and the vehicle speed information, whether leading to a target vehicle speed is required, the target vehicle speed being different from the vehicle speed indicated by the vehicle speed information, and controls, when leading to the target vehicle speed is required, the fake engine sound generator based on the target vehicle speed and the rotation speed information.

    Abstract: A makeup supporting device includes: a position acquisition unit that acquires a relative position of a predetermined indicator to a face; a contact determination unit that determines whether or not the indicator is in contact with the face; a makeup decision unit that decides a way of makeup to be applied to a facial image obtained by photographing the face, based on a contact position which is the relative position when the indicator is determined to be in contact with the face; and a makeup presentation unit that generates a simulation image by superimposing a makeup image on the facial image, the makeup image indicating a state of the makeup when the decided makeup is applied.
