Described referring to Fig.1, a specific embodiment of the invention provides a kind of LOGO projector comprising: memory, depending on
Frequency decoder, display screen and projecting subassembly.
Wherein, in LOGO projector provided by the invention, memory is mainly used for storing video pictures text to be projected
Part.It is understood that the present invention is not particularly limited the type of memory, as long as video pictures to be projected can be stored
File.It can also be appreciated that the present invention is also not particularly limited the format of video pictures file, can be
The various common video formats in this field.Meanwhile video pictures file stored in memory can be dynamic video text
Part is also possible to static image file, and it is not specifically limited to this by the present invention.For example, can be LOGO picture with shutter
The incisions such as formula, checkerboard type, dissolution type, news flash formula, fan out formula show that dynamic mode is fabricated to video pictures file.
It is understood that video pictures file stored in memory can be and be pre-stored in LOGO provided by the invention
In projector, the video pictures file copy that project will can also be needed into memory at any time.For example, of the invention some
In embodiment, LOGO projector further includes the file input interface for inputting video pictures file to be projected, the file
Input interface is connect with the memory, and the video pictures file that the file input interface inputs is stored in the storage
In device.In turn, the carry out LOGO picture change that the LOGO projector that this embodiment provides can be convenient is thrown without dismantling LOGO
Shadow machine, that is, the LOGO video pictures file for making novel and beautiful can be copied to LOGO projector by file input interface
In interior memory, i.e., replaceable dynamic projected picture.
It is understood that file input interface can using it is various can to the structure of memory input file, the present invention
It is not specifically limited to this.For example, in some embodiments of the invention, file input interface uses micro USB interface,
Micro USB interface it is versatile, facilitate LOGO projector and various exterior terminals to carry out data interaction, as mobile phone, IPad,
USB flash disk etc..
In LOGO projector provided by the invention, Video Decoder is for decoding video pictures stored in memory
File.It is understood that the main operational principle of Video Decoder is known to those skilled in the art, the present invention to this not
It repeats again.Certainly, according to the difference of video pictures file, decoding principle used by Video Decoder can also be different.
Corresponding vision signal is obtained after Video Decoder is by video pictures file decoding stored in memory, and
Vision signal is sent to display screen, in turn, display screen can show the video pictures of decoded video pictures file.
It is understood that the present invention is not particularly limited the type of display screen, various display screens can be used.
