    Abstract: A sound pickup device for picking up a target sound includes: a first input interface that inputs image data generated by a camera; a second input interface that inputs an audio signal output from a microphone array; a controller that determines a sound pickup direction in which the target sound is picked up, based on the image data and the audio signal; and an output interface that outputs information to be presented to the user. The controller determines whether an image indicated by the input image data and an audio sound indicated by the input audio signal are in a predetermined state. When determining that the image and the audio sound are in the predetermined state, the controller causes the output interface to output an instruction to the user, and inputs additional image data and an additional audio signal after the instruction is output, to determine the sound pickup direction.

    Abstract: A sound pickup device is a device that picks up target sound that has been output from an object serving as a sound source. The sound pickup device includes a controller that generates object location information indicating a location of the object on the basis of image data of a camera, generates sound-source location information indicating a location of the sound source on the basis of an acoustic signal of a microphone array, sets a weight for the object location information in accordance with an image capturing state of the camera, and determines a direction in which the target sound is to be picked up on the basis of the object location information, the weight for the object location information, and the sound-source location information.

    Abstract: An electronic device 100 according to one embodiment includes: a panel 101; vibrators 102 that vibrates the panel 101; and a vibration controller 109 that controls the vibrators 102 so that when positions of the panel 101 are simultaneously touched by the user, a vibration at a first touch position of the touch positions is greater than a vibration of a second touch position of the touch positions. The vibrators 102 include a first and a second vibrator 102. Where a distance between first touch position and the first vibrator 102 is equal to a distance between second touch position and the first vibrator 102, a transfer characteristic of vibration of the panel 101 between the first vibrator 102 and the first touch position is different from a transfer characteristic of vibration of the panel 101 between the first vibrator 102 and the second touch position.

    Abstract: The present disclosure provides a sound collection device that collects a sound while suppressing noise. The sound collection device includes: a storage that stores first data indicating a feature amount of an image of an object indicating a noise source or a target sound source; and a control circuit that specifies a direction of the noise source by performing a first collation of collating image data generated by a camera with the first data, and performs signal processing on an acoustic signal outputted from a microphone array so as to suppress a sound arriving from the specified direction of the noise source.
