Imaging device, and system for audio and image recording
An imaging device includes an interface, a controller, and a recorder. The interface is connected to an external device. The interface is configured to receive divided audio data obtained by dividing data included in an audio file obtained by the external device in units of time, from the external device. The controller performs correlating an image file with the divided audio data so that the image file and divided audio data are synchronized, based on time data of the image file obtained by image shooting, and time data of the divided audio data. The controller performs sending reduced image data obtained by reducing images included in the image file, to the external device through the interface. The recorder records the image file and divided audio data.
1. An imaging device comprising:
a first recorder which records an image file obtained by image shooting;
an interface which is connected to an external device and is configured to receive audio data from the external device, the external device records an audio file comprising audio data that is divided into a plurality of audio tracks by units of time; and
a controller configured to perform the following:
(1) correlate the image file with at least one audio track of the plurality of audio tracks by comparing time data of the image file and time data of the at least one audio track,
(2) send reduced image data obtained by reducing images included in the image file to the external device through the interface,
(3) play back the image file simultaneously with its correlated at least one audio track, and
(4) update the image file with correlation data.
2. The imaging device according to claim 1 , further comprising a reproduction module configured to play back the image file simultaneously with its correlated at least one audio track.
3. The imaging device according to claim 1 , wherein the image file is a still image file.
4. A system for image recording and audio recording, comprising:
an imaging device configured to record an image file;
an audio recording device configured to record an audio file, the audio file comprising audio data that is divided into a plurality of temporally-continued audio data tracks;
an interface connected to the imaging device and audio recording device;
a first controller configured to correlate an image file with at least one temporally-continued audio data track of the plurality of temporally-continued audio data tracks so that the image file and the at least one temporally-continued audio data track are synchronized, based on time data of the image file, and corresponding time data of the at least one temporally-continued audio data track;
a second controller configured to create a moving image container file configured to always be replayable by combining the image file and the at least one temporally-continued audio data track;
a first recorder which adds correlation data representing the correlated image file and the at least one temporally-continued audio data track to the image file, and records the image file; and
a second recorder configured to record the moving image container file.
5. The system according to claim 4 , further comprising:
a first reproduction module which reproduces the image file in the moving image container file in synchronization with reproduction of the at least one temporally-continued audio data track in the moving image container file; and
a second reproduction module which reproduces the at least one temporally-continued audio data track in synchronization with reproduction of the image file, to which the correlated data is added.
6. The system according to claim 5 , wherein the image file is a still image file.
