The useful effect of the present invention is: this audio-video collection system is in use, by the analysis of described analysis module, in the voice of collection in worksite, during as the discontinuous speech obviously paused occurs, then automatically it is judged to important voice content, this meets the feature of most of important voice content, such as leader's speech; Thus trigger described flash fire, make the video of now synchronous recording carries flicker signal secretly, such that it is able to effectively remind spectators to note, it is to increase spectators are for effective audiovisual efficiency of important content in audio frequency and video.
Accompanying drawing explanation
Fig. 1 is the structural representation of this audio-video collection system.
Fig. 2 is in this audio-video collection system, analyzes an example structure schematic diagram of module.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment shown in Fig. 1, Fig. 2, this audio-video collection system comprises microphone 1, camera 2; Described camera 2 exports storer 3 to, and described microphone 1 exports described storer 3 to after analyzing module 4 by one; Described analysis module 4 is analyzed for the output audio electric current of described microphone 1, and for each voice in audio frequency electric current, if having pause before this voice, then described analysis module 4 trigger flashing lamp 5 glistens; Described photoflash lamp 5 and described camera 2 are together towards audio-video collection side.
In fact, for comparatively important content, speaker can express usually with choosing one's words carefully, and words is slower, clear so that enunciating, it is convenient to audience note and do not hear, so, this kind is comprised to the voice of important content, in most of the cases, there will be obvious pause between two independent voices, such that it is able to analyzed out by described analysis module 4, and trigger described photoflash lamp 5 and glimmer; Make the video of now synchronous recording carries flicker signal secretly, thus when audio and video playing, can effectively remind spectators to note, it is to increase spectators are for effective audiovisual efficiency of important content in audio frequency and video.
In the present embodiment, described analysis module 4 as shown in Figure 2, comprise be linked in sequence mutual inductor 41, amplifier 42, wave filter 43, triggering device 44; Described mutual inductor 41 is coupled in the audio output line of microphone 1, makes the audio frequency electric current of microphone 1 directly export described storer 3 to, thus substantially eliminates the impact analyzing module 4 for original audio frequency electric current; Described triggering device 44, after a rise-time of current often being detected, triggers described photoflash lamp 5 and glistens once. By this scheme, when audio frequency electric current has continuous speech signal, due to the effect of wave filter 43, each speech signal in this kind of continuous voice is connected after mild, thus in the middle part of this continuous voice no current positive rise, a rise-time of current only occur in the beginning of this continuous voice, described photoflash lamp 5 glistens once;And when audio frequency electric current occurs slowly, interrupted voice time, when namely there is pause before speech signal, then each interrupted speech signal all carries a rise-time of current, then the corresponding each interrupted speech signal of photoflash lamp 5 glimmers respectively, to realize the prompting to this kind of voice.
