Abstract: An image generating device has a camerawork information extracting unit that extracts imaging information of a captured image, a composition information calculating unit that temporarily decides a cut-out frame for cutting out a new image from the imaging information and the captured image based on a constraint condition, and decides a cut-out frame to smooth a change of the new image between frames, from the temporarily decided cut-out frame, each of the frames being a unit of an image, and a composition information shaping unit that cuts out the new image from the captured image by using the cut-out frame, and converts a size of the new image to a predetermined size. The new image generated from the captured image becomes a favorable image that is easy to see for a viewer, and particularly a more smooth and natural image, without any skilled imaging techniques during capturing.

Abstract: The voice control device includes a sound source signal input unit, a frequency determination unit, a band controller, a sound image controller, and a voice output unit. The sound source signal input unit inputs a sound source signal of content from a sound source. The frequency determination unit determines a cutoff frequency. The band controller acquires a high frequency signal in a frequency band equal to or higher than the cutoff frequency and a low frequency signal in a frequency band equal to or lower than the cutoff frequency, from the sound source signal of the content. The sound image controller generates a plurality of sound image control signals for controlling sound images of the plurality of speakers, by controlling at least one of a phase and a sound pressure level of the high frequency signal. The voice output unit outputs the low frequency signal to a first speaker, and outputs the plurality of sound image control signals to a second speaker composed of a plurality of speakers.

Abstract: With the noise reduction device (300), in identifying an acoustic transfer function that includes a path from the control speaker (340) to the error microphone (350) or the noise microphone (320) by outputting an identification sound from the control speaker (340) and detecting the identification sound with the error microphone (350) or the noise microphone (320), the identification controller (338) is configured to identify the acoustic transfer function by generating the identification sound from the white noise generator (337) when the seat detector (582) has detected that the seat is in the actual usage state for noise reduction.

Abstract: In a noise reduction device that generates and outputs a control sound signal for reducing noise, an internal loop control unit controls an internal loop in which a pre-output control sound signal that is acquired from a control sound output unit before output to a speaker is input to a sound receiver. A measurement unit measures an input level of a microphone sound signal and an input level of the pre-output control sound signal that has been input to the sound receiver in the internal loop. A fault detector uses the input level of the microphone sound signal and the input level of the pre-output control sound signal measured by the measurement unit to detect a fault in any one of the microphone, the sound receiver, the speaker, and the control sound output unit. A transmitter sends a result of fault detection performed by the fault detector to a management device.

Abstract: An image generating device has a camerawork information extracting unit that extracts imaging information of a captured image, a composition information calculating unit that decides a cut-out frame for cutting out a new image from the imaging information and the captured image based on a constraint condition, and a composition information shaping unit that outputs, as attribute information of the captured image, the imaging information and the cut-out frame. This configuration makes it possible to obtain from a captured image a newly generated image which is a favorable image that is easy to see for a viewer, without requiring skilled imaging techniques during capturing, and to efficiently record and manage the captured image and the newly generated image.
