Problems solved by technology

[0007] However, in the method of generating synchronization information using level information of acoustic data disclosed in Japanese Patent Laid-Open No. 2009-10548, synchronization information cannot be generated in a robust manner with respect to noise sounds
Furthermore, even in the method of generating synchronization information using the correlation of acoustic data disclosed in Japanese Patent Laid-Open No. 2010-171625, synchronization information cannot be generated in a robust manner with respect to noise sounds
Furthermore, in the disclosure of Japanese Patent Laid-Open No. 2010-171625, since correlation is calculated focusing only on partial intervals of acoustic data, synchronization over time due to slight differences in internal clock frequencies between devices cannot be corrected difference

[0039] [Explanation of the outline of the first embodiment of the signal processing system]

[0040] figure 1 is a block diagram showing a configuration example of the first embodiment of the signal processing system to which the present disclosure is applied.

[0041] Such as figure 1 As shown, a signal processing system 10 includes imaging devices 11 - 1 and 11 - 2 and a signal processing device 12 .

[0042] The imaging device 11-1 includes a video camera and the like. The imaging device 11-1 acquires dynamic images and sounds of the same event, which are different from those in the imaging device 11-2. The imaging device 11 - 1 sends the resulting content A of moving images and sounds to the signal processing device 12 .

[0043] Similar to the imaging device 11-1, the imaging device 11-2 includes a video camera and the like. The imaging device 11-2 acquires dynamic images and sounds of the same event, which are different from those in the imaging device 11-1. The im...

[0132] [Explanation of the outline of the second embodiment of the signal processing system]

[0133] Figure 11 is a view for explaining the outline of the second embodiment of the signal processing system to which the present disclosure is applied.

[0134] exist Figure 11 In the components shown, the same reference numerals are assigned to the figure 1 The same components as the components in . Duplicate explanations will be sufficiently omitted.

[0135] Figure 11 The configuration of the signal processing system 140 in the figure 1 The difference in configuration is that an imaging device 141 is newly provided, and a signal processing device 142 is provided instead of the signal processing device 12. The signal processing system 140 generates synchronization information of content acquired by the three imaging devices.

[0136] More specifically, like the imaging device 11, the imaging device 141 of the signal processing system 140 includes a video camera or the ...

[0143] 【Configuration example of signal processing system】

[0144] Figure 12 is a view for explaining the outline of the third embodiment of the signal processing system to which the present disclosure is applied.

[0145] here, in Figure 12 Components shown in , the same reference numerals are assigned to the figure 1 The same components as the components in . Duplicate explanations will be sufficiently omitted.

[0146] Figure 12 The signal processing system 370 in includes the imaging devices 11 - 1 and 11 - 2 , a signal processing device 371 and a server 372 .

[0147] The signal processing device 371 includes figure 1 The feature quantity extracting parts 21-1 and 21-2 in. The signal processing device 371 calculates feature amount time-series data based on the acoustic data of content A supplied from the imaging device 11-1, and calculates feature amount time-series data based on the acoustic data of content B supplied from the imaging device 11-2. The signal...

Abstract

Signal processing apparatuses, systems and methods, programs and electronic devices are provided. A signal processing device comprising: a first periodicity detection part for detecting periodicity information of a sound signal included in a first content as first periodicity information; a second periodicity detection part for detecting a sound signal included in a second content The periodic information is used as the second periodic information; the similarity calculation component calculates the similarity between the first periodic information detected by the first periodic detection component and the second periodic information detected by the second periodic detection component; and synchronization information generating means that generates synchronization information used when synchronizing the first content and the second content based on the degree of similarity calculated by the degree of similarity calculation means.

Description

technical field [0001] The present disclosure relates to a signal processing device, a signal processing method, a program, an electronic device, a signal processing system, and a signal processing method thereof. More particularly, the present disclosure relates to a signal processing device, a signal processing method, a program, an electronic device, a signal processing system, and a signal processing method thereof capable of generating synchronization information of content in a robust manner. Background technique [0002] In the case of reproducing or editing content obtained by recording images or sounds of the same event by a plurality of devices in synchronization with time, it is necessary to find time synchronization between the contents. This is because, even in the case of recording images or sounds of the same event, recording start times differ between devices, and a time delay occurs because internal clock frequencies slightly differ between devices. Here, t...
