Fig. 2 is the structural representation of the take pictures data processing equipment and the external unit thereof that are used for portable terminal of the embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing to a preferred embodiment of the present invention will be described in detail.
Fig. 2 is the structural representation of the data processing equipment of taking pictures that is used for portable terminal of the embodiment of the invention.As shown in Figure 2, the data processing equipment of taking pictures that is used for portable terminal of the present invention comprises DirectShow assembly and photo module.Wherein, The DirectShow modular construction still is original assembly as shown in Figure 1; It comprises source filter, switched filter and reproduction wave filter, and different is that original DirectShow assembly directly obtains files such as picture from the outside when non-taking pictures; For example obtain files such as picture from local file system or internet etc., the source filter when taking pictures in the assembly calls the hardware camera arrangement and takes pictures to obtain files such as picture; And outside DirectShow, further encapsulated a photo module in the present embodiment; Said photo module comprises file acquisition module, file conversion module and document processing module; File acquisition module by photo module when non-taking pictures obtains files such as picture from the outside, start the hardware camera arrangement and take pictures operation to obtain picture thereby when taking pictures, call source filter in the DirectShow assembly by the file acquisition module of photo module.
In addition; Switched filter in original DirectShow assembly directly calls hardware decoder the file that obtains is carried out format conversion, and utilizes said file conversion module in the photo module to call the switched filter in the DirectShow assembly and then call the files such as picture that hardware decoder obtained the file acquisition module and carry out format conversion in the present embodiment; Reproduction wave filter in original DirectShow assembly carries out predetermined process and exports external units such as sound card, graphics card or scrambler to the file through format conversion, and the reproduction wave filter that utilizes the document processing module in the photo module to call in the DirectShow assembly in the present embodiment comes the file through format conversion is handled.
Thereby the document input module that obtains picture when wherein said file acquisition module is included in non-taking pictures from local file system or internet calls source filter the DirectShow assembly when taking pictures and for example opens the hardware camera arrangement of WDM trap setting and take pictures operation to obtain the capture module of picture.When operation, the document input module in the file acquisition module is connected with local file system with the internet, to realize from the internet or local file system reception picture; Perhaps photo module is sent the instruction to the capture module in the file acquisition module; Said capture module can make the supply filter of DirectShow assembly for example open the operation of taking pictures of the hardware camera arrangement of WDM trap setting, and receives and preserve the picture of taking pictures and obtaining.
Behind the for example picture file that the file acquisition module receives and preservation is obtained picture is transferred to the file conversion module, hardware Mmpeg2 hardware decoders demoder converts the picture file that is obtained to the file layout that needs to the converting filter of said file conversion module invokes DirectShow assembly for example to start.For example file conversion module can be called said switched filter and convert the original RGB picture file that said file acquisition module is obtained into the JPEG picture file.
The picture of accomplishing format conversion is transported to document processing module, and said document processing module can comprise piece processing module and stream processing module, and piece is handled or stream is handled in order to the picture file through format analysis processing is carried out.Document processing module comes picture is carried out bulk treatment through the reproduction filtrator that calls the DirectShow assembly; The stream that said stream processing module is carried out is handled can carry out byte-by-byte processing to picture, therefore can handle to improve precision picture from whole and details two aspects.
Document processing module in the photo module also is used for picture is after treatment exported to be sent to outside module.
The data processing equipment of taking pictures that is used for portable terminal of the embodiment of the invention can make the developer just can directly call the picture compression function through easy parameter setting, has improved development efficiency, has reduced the possibility that makes a mistake.
The data processing method of taking pictures that is used for portable terminal that the embodiment of the invention proposes may further comprise the steps:
S11, obtain picture from the outside or call source filter module the DirectShow assembly and open the hardware camera arrangement and take pictures to obtain picture through the file acquisition module in the photo module, document input module is transferred to the file conversion module in the photo module with picture;
S12, convert the picture that obtains into predetermined form through the switched filter in the file conversion module invokes DirectShow assembly, the picture that the file conversion module will be accomplished conversion is transferred to the document processing module in the photo module;
S13, call reproduction wave filter in the DirectShow assembly to handling through the picture of format conversion through document processing module;
S14, treated picture is exported to be sent to external module through document processing module.
In the above-mentioned S12 step, can convert the original RGB picture file that the file acquisition module is obtained into the JPEG picture file through file conversion module invokes switched filter.
Data processing equipment and the method for taking pictures of the present invention is through to the further standard photo module of encapsulation of original DirectShow assembly; Thereby can be directly and bottom hardware and modular converter communicate; Make the user need not to call under the situation of bottom API or com interface also the operation that can use always camera, shortened the procedure development cycle to a great extent.
The smart mobile phone that take pictures data processing equipment and method of the present invention not only can be used for Windows Mobile platform also can be applicable to handheld terminals such as industrial PDA, is widely used.
The preferred embodiments of the present invention have more than been described; But the present invention is not limited to above-mentioned particular implementation example; Do not deviating under spirit of the present invention and the nature thereof; Skilled personnel can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong within the accompanying claims protection domain of the present invention.
