According to appearance, fully rely on the traditional video surveillance system manually supervised and be unable to meet demand, people need it is more intelligent,
Automation, the video monitoring system of autonomy-oriented, therefore intelligent video monitoring system become lifting video monitoring system efficiency
The main direction of development.
It is increasing to possess the electronic product of recording function on the market, but these electronic product overwhelming majority are required for possessing
The caching process that video process provides picture is saved as in larger.However, with the compression of electronic product production cost, how to cause
Product ensures its equal function while production cost is reduced, such as which data can be differentiated is key data, which
Data are low priority data, become the hot spot of industry research to improve the competitiveness of electronic product.
The content of the invention
It is existing to solve it is an object of the present invention to provide a kind of method using a variety of compress mode recorded videos
The problem of cannot carrying out classified compression to video in technology.
Especially, the present invention provides a kind of method using a variety of compress mode recorded videos, including：
S1, receives record command, creates a recorded file in memory, and gathers video data, by the video of collection
Data buffer storage is into memory random access memory；Wherein, video data is the raw image data captured by camera sensor；
S2, when the video data in the random access memory reaches a preset value, continues to gather video data, wherein,
The residual memory space of the memory is detected, when the residual memory space of the memory is less than preset value, described in traversal
Video data in random access memory, will include moving target respectively and does not include in the video data in the random access memory
The data content of moving target carries out video compress with different compress modes；
S3, recorded file is write by compressed video data.
Alternatively, the different compress mode, which carries out video compress, includes：
Obtain at least two frames of the difference preset time in video；
Contrast the pattern of two frame；
If the pattern of two frame is approximate, the first compress mode is taken, if the pattern of two frame is had any different, is taken
Second of compress mode.
Alternatively, the different compress mode includes H.26X series, MPEG series etc..
Alternatively, the first compress mode or the second compress mode are used when starting recorded video, when the figure of two frame
When case is approximate, the compress mode is constant；When the pattern of two frame is had any different, the compress mode changes.
Alternatively, video compress is the video file with the first default clarity by shown first compress mode, described
Video file compression is the video file with the second default clarity by the second compress mode.
Alternatively, the video file with the first default clarity of equal time is preset clearly with described with second
The memory that the video file of clear degree takes is different.
Alternatively, the preset time is 1S.
The method using a variety of compress mode recorded videos of the present invention, due to respectively by regarding in the random access memory
Data content of the frequency in comprising moving target and not comprising moving target carries out video compress with different compress modes, because
This can farthest save storage memory, moreover it is possible to classify to information, it is ensured that important information completely preserves.
Further, the pattern correspondance at least two frames that the present invention passes through the difference preset time in video, to carry out not
Same compress mode carries out video compress, can effectively improve recognition efficiency, reduces error.
According to the accompanying drawings will be brighter to the detailed description of the specific embodiment of the invention, those skilled in the art
Above-mentioned and other purposes, the advantages and features of the present invention.
