The present technology relates to a data processing device, a data processing method, a program, and a data processing system which enable recording of meaningful sound for intermittent images. A data processing device includes a sound extracting unit that extracts one or more sound blocks to be reproduced together with video data based on the plurality of images, on the basis of a predetermined characteristic quantity from sound data corresponding to sound captured within a period in which a plurality of intermittent images has been captured. The present technology is applicable to, for example, a recording device that performs interval imaging.

A spherical content capture system captures spherical video and audio content. In one embodiment, captured metadata or video/audio processing is used to identify content relevant to a particular user based on time and location information. The platform can then generate an output video from one or more shared spherical content files relevant to the user. The output video may include a non-spherical reduced field of view such as those commonly associated with conventional camera systems. Particularly, relevant sub-frames having a reduced field of view may be extracted from each frame of spherical video to generate an output video that tracks a particular individual or object of interest. For each sub-frame, a corresponding portion of an audio track is generated that includes a directional audio signal having a directionality based on the selected sub-frame.

An audio signal processing apparatus including a receiving unit receiving an input audio signal, a processor generating an output audio signal reproducing a virtual sound source corresponding to the input audio signal in a virtual space, and an output unit outputting an output audio signal generated by the processor is disclosed. The processor may obtain spatial information related to the virtual space including a virtual sound source corresponding to the input audio signal and a listener, filter the input audio signal based on a location of the virtual sound source and the spatial information to generate at least one reflected sound corresponding to each of at least one mirror plane in the virtual space, obtain a relative location of a virtual reflect sound source with respect to a location and a view-point of the listener, based on information of the view-point of the listener and a location of the virtual reflect sound source corresponding to each of the at least one reflected sound, and binaural render the at least one reflected sound, based on the relative location of the virtual reflect sound source corresponding to each of the at least one reflected sound.

An object is to clarify a correspondence relation between a subject that is an audio source in image data and audio emitted from the subject. When image data having audio data is acquired, this image data having audio data is analyzed so as to identify a subject that is an audio source in the image data. Then, audio data corresponding to the subject identified as the audio source is selected from the acquired successive audio data, and this audio data and the subject are associated with each other. In this case, for example, the audio data corresponding to the subject is outputted in association with the display of the subject that is the audio source, or in other words, in synchronization with the image display.

An imaging system includes a sound recording apparatus and an imaging apparatus that is connected to the sound recording apparatus and records, as moving-image sounds, sounds collected by the sound recording apparatus. The imaging apparatus detects whether the sound recording apparatus has been connected thereto. Upon detecting that the sound recording apparatus has been connected to the imaging apparatus, the imaging apparatus sets a sound-recording condition associated with the sound recording apparatus as a sound-recording condition for the imaging apparatus in a sound recording process and records sounds under the sound-recording condition that has been set.

An electronic camera device, and associated system and interfaces, that generates, records and transmits video, audio and sensor data. Camera device comprises a housing with a fastening mechanism adapted to mount the device to a firearm. The device has a processor module, a memory module for storage, a camera module configured to generate and record video and store the video to memory. The device further includes a magnetic sensor configured to detect the presence and absence of a magnet and an accelerometer that is configured to detect a draw motion (e.g., a firearm being unholstered). When the magnetic sensor detects the absence of a magnet, and the accelerometer detects a draw motion, one or more corresponding signals are generated and transmitted, directing the camera to begin recording (and transmitting) video and send an alert signal to assets in the field to provide support.
