A mobile terminal including a display configured to display information; a short range communication module configured to exchange a signal with an external control device; and a controller configured to receive the signal from the external control device, determine a context at a timing point of receiving the signal, and control an operation corresponding to the signal to be performed in the determined context. Further, the operation includes at least one of activation/deactivation of the display, an activation/deactivation of a lock mode of the mobile terminal, a volume operation and a camera operation.

Mobile terminal and controlling method thereof

A method for controlling a head mounted display (HMD) includes detecting an external device, displaying an augmented reality image as a first mode, changing the first mode to a second mode when the gaze of the user to the augmented reality image is detected in the first mode, and executing a function corresponding to the augmented reality image when the augmented reality image and the external device are aligned in the second mode. The first mode is a mode in which a display position of the augmented reality image depends on a position of the external device the second mode is a mode in which the display position of the augmented reality image remains fixed even when the position of the external device is changed.

Head mounted display and method for controlling the same

A method for signal level matching by an electronic device is described. The method includes capturing a plurality of audio signals from a plurality of microphones. The method also includes determining a difference signal based on an inter-microphone subtraction. The difference signal includes multiple harmonics. The method also includes determining whether a harmonicity of the difference signal exceeds a harmonicity threshold. The method also includes preserving the harmonics to determine an envelope. The method further applies the envelope to a noise-suppressed signal.

Systems and methods for audio signal processing

Systems and methods for multi-sourced noise suppression are provided. An example system may receive streams of audio data including a voice signal and noise, the voice signal including a spoken word. The streams of audio data are provided by distributed audio devices. The system can assign weights to the audio streams based at least partially on quality of the audio streams. The weights of audio streams can be determined based on signal-to-noise ratios (SNRs). The system may further process, based on the weights, the audio stream to generate cleaned speech. Each audio device comprises microphone(s) and can be associated with the Internet of Things (IoT), such that the audio devices are Internet of Things devices. The processing can include noise suppression and reduction and echo cancellation. The cleaned speech can be provided to a remote device for further processing which may include Automatic Speech Recognition (ASR).

Multi-Sourced Noise Suppression

An information apparatus is provided with: a comment processing unit that acquires, from an external posting site, a comment of a viewer by using a tag as a search key, the comment is a viewer's feedback on the content of a program being viewed and related to a tag for grouping with other comments; and a display processing unit that generates data to be displayed on a screen, the data include image of a program being broadcast by a first broadcasting station and at least one comment for a program being broadcast by a second broadcasting station different from the first broadcasting station.

Information processing apparatus and information processing method

In a wind noise reduction device that reduces wind noise contained in an input sound signal to generate a corrected sound signal, when a predetermined band including the band of the wind noise is a first band and a predetermined band higher in frequency than the first band is a second band, the wind noise reduction device includes: a first corrector that has a signal generator generating, based on a sound signal (i) contained in the input sound signal and lying in a band higher in frequency than the first band, a sound signal (ii) lying in the first band and different from a sound signal (iii) contained in the input sound signal and lying in the first band, and that generates a first corrected sound signal based on the sound signal (ii) generated by the signal generator; a second corrector that reduces the signal level of a sound signal (iv) contained in the input sound signal and lying in the second band to thereby generate a second corrected sound signal as a sound signal (v) having the wind noise reduced and lying in the second band; and a corrected sound signal outputter that outputs the corrected sound signal based on the first and second corrected sound signals.

A sound signal processing device has a signal outputter which outputs a target sound signal obtained by collecting sounds from a plurality of sound sources, and a sound volume controller which adjusts the sound volumes of the individual sound sources in the target sound signals according to the directions or locations of the sound sources and according to the types of the sound sources.

Sound Signal Processing Device And Playback Device

Sound correction processing is performed for a sound signal obtained from a sound collecting portion. In particular, sound correction processing is performed after determining what is performed as the sound correction processing based on an image signal paired with a sound signal, the image signal obtained from an imaging portion, the sound signal, control data of the imaging portion, and the like.

Sound corrector, sound recording device, sound reproducing device, and sound correcting method

An imaging apparatus incorporating a plurality of scene modes is provided with: an automatic appropriate mode determining portion that, while shooting of a moving image is in progress, automatically determines at least one scene mode appropriate for a shooting scene of the moving image; and a scene mode comparison portion that compares a currently selected scene mode with the at least one scene mode automatically determined by the automatic appropriate scene mode determining portion, and that thereby confirms whether or not the currently selected scene mode corresponds to any one of the at least one scene mode automatically determined by the automatic appropriate scene mode determining portion.

Imaging Apparatus And Mode Appropriateness Evaluating Method

An image audio processing portion includes an image analysis portion for analyzing an input image, a directivity control portion for controlling a directivity of an input audio signal based on a result of analysis by the image analysis portion so as to generate an output audio signal, and a display image generating portion for generating a display image by superimposing an image indicating a state of the output audio signal on the input image A user can recognize a state of the output audio signal by checking the display image
