Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is elaborated.
The invention provides the processing method of a mobile-terminal frame carboon.Adopt the frame animation technology generation for vector animation technology playing animation on portable terminal, the present invention specifically can be divided into the Code And Decode two large divisions.
Fig. 1 is the workflow schematic diagram of image encoding of the present invention.As shown in the figure, the process of coding specifically may further comprise the steps:
Step S101 carries out the interframe compression to image;
Step S102 carries out compressing in the frame to image;
Step S103 judges whether relevant audio of image, if relevant audio then enters step S104, if do not have, then enters step S106;
Step S104 writes the index of related audio in the image head of picture frame, enter step S106 again;
Step S105 compresses the audio data;
Step S106 writes UFO (UniFrame Object, UNI frame object) animation file with audio data and view data after the compression.
Each concrete steps among Fig. 1 are described in detail in detail below:
Fig. 2 is the workflow schematic diagram that compresses between picture frame of the present invention.The present invention supports PNG (PortableNetwork Graphic Format, streaming network graphic form), two kinds of coding format of BMP (Bitmap, bitmap).Two characteristics that we need utilize PNG/BMP to have:
It is transparent that characteristic one: PNG/BMP can support that all the part is provided with;
Characteristic two: two color of image of same area are can reduce on the file volume much than color complexity simply.
Consider that animation is a continually varying, the similarity of its consecutive frame image is very high, and the present invention handles the elimination of the repeating data that realizes adjacent two two field pictures with local transparence.For example, successive image frame A-B-C-D is arranged, the difference that compares the second frame B image and the first frame A image, because the size of two two field pictures is the same, can be from the upper left corner of image, the color of two figure at same locational pixel compared in pointwise, illustrates that if color is identical this point is repetition, can eliminate.So we replace current color with self-defining Transparent color, the color relation of this point is replaced by Transparent color like this, that is to say that this point " transparence ".Travel through complete image and just can obtain a new B two field picture (wherein the color with respect to the repetition pixel of A frame all replaces with Transparent color), i.e. B ' two field picture.
In fact, if we compare in pointwise, not only processing speed is slower, and too scattered brocken spectrum can not really improve the compression ratio of image, according to the characteristic two of PNG/BMP, the file size that reduce image should have large-area monochrome (Transparent color) that good effect just can be arranged.So we compare as a processing unit (image block) with 8 * 8 pixels, in one 8 * 8 square, not to repeat a little promptly as long as a point is arranged, then all think current entire image piece (8 * 8 pixels) unduplicated.Have only also must 8 * 8 pixels all identically, just the pixel with this image block all replaces to Transparent color.
Can restore B according to A image that has obtained and the merging of B ' process at portable terminal, promptly play up the A image earlier, simply B ' is superimposed upon on the A then, because B ' has been replaced by Transparent color with the pixel of A same section, portable terminal can be ignored these pixels with Transparent color, so pixel on same position of the A image under just demonstrating, and B ' goes up and the pixel of the part that A is inequality, owing to do not replaced, so still show the pixel of B ' image in this position by Transparent color.Final whole structure is exactly to have shown original B image on screen.
The present invention utilizes Transparent color to replace and realizes image " hollow out ", compare with " hollow out " technology among the documents CN1035797C, be by only deriving (non-blank-white) inequality parts of images pixel data in the documents, the method that the same section image pixel data abandons fully realizes, the pixel data (the data incompleteness must could be recovered through computing) that has only parts of images inequality among the B '.The present invention still is retained in (data integrity, simple superposition can be recovered) in B ' image after same section image slices vegetarian refreshments is replaced with Transparent color.Briefly, the difference that is exactly the present invention and documents is, documents is not that the color of pixel is operated but the binary data of direct control image file, needs deleted data during hollow out, need calculate the data of recovering deleted during reduction.And the present invention is on the contrary, is the binary data of the color of the pixel of image being operated rather than operated image file, need replace color during hollow out, does not need to do any processing during reduction.
Same, the MPEG technology has also adopted the interframe compression in the known technology, but it is based on the realization of motion compensated prediction technology, need carry out a large amount of calculation process.And, in order to obtain maximum compression ratio, the interframe compression of MPEG also is repeating data to be deleted (being that B ' is the data block of an incompleteness) from two field picture, the color that the present invention utilizes the characteristic of Transparent color to carry out whole pixels in the identical image piece is replaced the forward direction/bi-directional predicted technology that replaces MPEG, and guarantee complete (just the color of partial pixel point is replaced by another kind of color) of the middle data of B ', simplified the calculating process when reduction so to greatest extent.In the present invention, because B ' also is an effective picture frame (just having partial pixel to be replaced by another kind of color in the image), can directly show, just can obtain original B image on the A image (this reduction process is not to restore real B image by computing as long as its stack is presented at, just showing the B image on mobile terminal screen gets final product, in fact the present invention does not obtain a real B image, and just shows the B image on the screen).Compare MPEG and documents CN1035797C, they all are to restore real B image in internal memory by computing, then the B image are rendered on the screen.
Therefore, the present invention and MPEG and documents compare, and the method for employing is simple relatively, have the reduction characteristics that operand is little, image fault is little, are more suitable for realizing on portable terminal.
Whether following table has been described through transparence and has been handled influence to final animation file size:
As shown in Figure 2, compression specifically may further comprise the steps between picture frame:
Step S201 opens the two continuous frames image;
Step S202 is divided into the 8x8 image block with every two field picture;
Step S203, the pixel of the image block of the correspondence of two picture frames that recycle ratio is more adjacent, judge whether two image pixels in the image block are identical, if all pixels of two image blocks are all identical, think that then these two image blocks are identical, enter step S204,, then enter step S205 if all inequality;
Step S204 carries out transparence with the picture block identical with former frame in one frame of back and handles (promptly replacing with specific Transparent color), enters step S205 again;
Step S205, with the back one frame the complete image pixel data write in the corresponding UFO file data blocks.
Fig. 3 is the workflow schematic diagram of compression in the picture frame of the present invention.The present invention selects to support two kinds of coding format of PNG, BMP.Because animation is made up of a plurality of static map picture frames, and including image head, every static frames image (writes down the type of this image, color depth, palette, width, data such as height) and concrete image pixel data, for one section animation, the image head data of every static images that it comprised are just the same, therefore, if the data of in each frame, not preserving these file headers, (the BMP animation with 100 frames is an example can to save bigger space, its image head accounts for 54 bytes, so just can reduce by 5400 bytes), the data in each frame are only preserved concrete image pixel data (being the specifying information of each pixel of two field picture).As mentioned above, the present invention extracts the data of the file header of each two field picture, is encoded into the data of 8+X form, writes final animation file (specific coding form and performing step are described in detail in " Fig. 6-UFO document No. ").Simultaneously, GZIP (the GeneralPublic License ZIP) compression method by standard compresses processing with the image pixel data of each two field picture, has also reduced the data volume size in the frame.By above dual mode, can obtain littler frame data.Contrast MPEG technology, that MPEG adopts is complicated discrete cosine transform (Discrete Cosine Transform, DCT) compression (being the compress technique of similar JPEG) in the achieve frame, yet the present invention pieces together the complicated DCT technology of having abandoned, adopt the compression in the method achieve frame of cutting down the image common data simply, and can decode quickly and play up, be adapted at realizing on the portable terminal.
As shown in Figure 3, compression specifically may further comprise the steps in the picture frame:
Step S301, extracting goes out the image head data of this image from each static map picture frame;
Step S302 judges whether this static map picture frame is first frame of animation file, if, then enter step S303, if not, step S304 then entered;
Step S303, with the image head data (essential information that comprises current frame image in this static map picture frame, as information such as length and width, color depths, in all two field pictures, the content of image head data all is the same, therefore the image head data that only need preservation first frame) be encoded into a common image data (8+X form) and write in the UFO animation file, enter step S304 again;
Step S304 extracts the image pixel data in each static map picture frame;
Step S305 carries out the GZIP compression to the image pixel data of extracting;
Step S306 writes the image pixel data after the compression in the UFO animation file.
Fig. 4 is the workflow schematic diagram of audio compression of the present invention.The present invention supports MIDI (MusicalInstrument Digital Interface, a kind of audio format of standard), QCP (Qualcomm ' sPurevoice, the audio format of Qualcomm's definition), three kinds of audio coded formats of MMF (APP Mind Messagement File, the audio format of Yamaha company definition).
Wherein, the audio compression step comprises: at first, animation source audio is carried out segmentation, obtain a plurality of audio segment files (still keeping original audio coded format), the audio sequence that promptly complete animation comprised.Then, read each audio segment file respectively, carry out standard GZIP compression and handle, the audio segment data after obtaining compressing, coding advances UFO animation file (if be provided with related audio, then need carry out the operation associated of audio and image earlier when coding).
Compare MEPG, audio coding among the MPEG is to adopt own MP3 (Moving PictureExperts Group Audio Layer III, a kind of audio compression techniques)/and AAC (advanced acoustic coding technology) scheme, can not be supported by most of portable terminal.And audio and the image processing of MPEG are similar, also be with (being a series of continuous audio frames) of dividing frame to realize, and the present invention adopt the audio segmentation." audio section " is thicker than " audio frame " granularity, and the processing when decoding is play is also simpler, relatively is adapted at realizing on the portable terminal.And, consider most of portable terminals built-in to the decoding technique of GZIP packed data, therefore, use the GZIP compress technique can utilize the operational capability of portable terminal self more fully.
The present invention also supports the broadcast of background music, compares with audio, and background music is a complete music data, does not need to carry out segment processing.So the present invention handles the audio section that background music is regarded a specific type as, does not have special treatment step in cataloged procedure.
As shown in Figure 4, the audio compression specifically may further comprise the steps:
Step S401 is cut into a plurality of audio sections (maintenance original coding) with the segmentation of animation audio initial data;
Step S402 opens each audio segment file respectively;
Step S403 reads the data in each audio segment file, it is carried out the GZIP compression handle, and is compressed into the audio blocks of data in the UFO file;
Step S404 judges whether this audio segment file has specified the audio association, if, then enter step S405, if not, step S406 then entered;
Step S405 is provided with the association (the related audio piece index of record in the image frame data head) between this audio blocks of data (coming from current audio segment file) and the corresponding view data, enters step S406 again;
Step S406 will write the UFO animation file through the audio blocks of data that top step obtains.
Fig. 5 is the audio of the present invention workflow schematic diagram related with image.The present invention has set some special frames (key frame) in sequence of image frames, preserve the index of the audio piece of an association in the data head of key frame, to reach the effect that audio is related with respective image.This step mainly is exactly to preserve the index value of an audio blocks of data associated therewith at image key frame data head.And guarantee that this audio blocks of data because playing up in this key frame images, should guarantee that its associated audio was decoded in advance and can play before the position of UFO animation file is arranged in this key frame view data.For example: preserve the related audio piece 01 of a byte 01 this picture frame of expression, play sound effect section 01 when showing this picture frame in front at picture frame; If being 00 this two field picture of expression, this byte do not have related audio.MPEG is because audio also is the branch frame, so do not need to carry out such processing.
As shown in Figure 5, audio is related with image specifically may further comprise the steps:
Step S501 reads the index value of audio blocks of data;
Step S502 reads the single-frame images data index value;
Step S503 carries out the UFO coding to the audio blocks of data;
Step S504 carries out the digital coding of UFO single-frame images.
Fig. 6 is the workflow schematic diagram of UFO document No. of the present invention.Compress the data of each picture frame that obtains after handling in the process frame, and compress the data of handling the audio frame that obtains through audio, in our the final animation file of encoding successively, this file designation is the UFO file.Each UFO file comprises a plurality of data, and each data is made up of the build of 8 bytes and the block of X byte again.Wherein, the form of each data 8 byte build is similar substantially, as shown in the table:
Wherein two byte ' Q ' in " background music data " and " audio data ", ' this section of C ' expression audio preserves with the QCP form, if be ' MF ' expression is with the preservation of MMF form, if be ' MD ' expression preserves with midi format.
Music identification is the sign that " background music data " and " audio data " are distinguished, and identifies according to this when decoding and carries out different processing.
The audio index is effectively quoting the audio numbering.For example, the audio numbering: 1,2,3, expression has three sections audios.And audio index 2 these two field pictures of expression are quoted second section audio (being audio 2).The audio numbering is unique, and the audio index is recursive, and for example: two different two field pictures can be quoted same section audio, and their audio index is the same so.
And as follows by a plurality of UFO animation file forms of forming:
| The UFO file header | The common image head | Background music data | Audio data (N) | View data (N) |
| 8+X | 8+X | 8+X | N *(8+X) | N *(8+X) |
At first, write the public documents head (information that has comprised the UFO file of UFO animation file, as version number etc.), then write a common image data (this is the public head of image frame data in the whole animation file, will restore complete view data according to this public head in the future).Then, travel through data after the compression of each picture frame, judge whether that this image is a key frame, if key frame, the audio segment data (also being after compression) with association writes animation file earlier, then writes this image frame data again.If not key frame, this image frame data of then writing direct.As shown in Figure 6, coding UFO file specifically may further comprise the steps:
Step S601 writes UFO file header information;
Step S602 writes UFO common image information (comprising the common image header) in the UFO file;
Step S603 begins circulation every frame image data is carried out the UFO coding;
Step S604 judges the view data relevant audio whether in every frame, if having, then enters step S605, if do not have, then enters step S606;
Step S605, if relevant audio, then the audio blocks of data with association writes the UFO file, enters step S606 again;
Step S606 writes the single-frame images data in the UFO file.
Fig. 7 is the workflow schematic diagram of image data decoding of the present invention.Decoding is the inverse process of coding, is the process that specific animation file form (UFO) is illustrated in portable terminal.Because when coding UFO file, taken into full account the simplicity requirement of decoding, so whole decoding scheme relative coding scheme is simply many, specifically comprised: audio reduction step and picture frame reduction step.As shown in Figure 7:
Step S701, decoding UFO file reads the UFO original data stream;
Step S702 judges whether relevant audio of this UFO original data stream, and whether the index of audio piece of the association of preservation is promptly arranged in the sequence of image frames, if having, then enters step S703, if do not have, then enters step S704;
Step S703, if relevant, then elder generation reduces to the audio blocks of data of association, enters step S704 again;
Step S704 reduces to the view data in the UFO file.
Wherein, the audio reduction step is the inverse process of audio compression step.Fig. 8 is the workflow schematic diagram of audio reduction of the present invention.As shown in the figure, may further comprise the steps:
Step S801 reads the data block in the current UFO file, if the audio blocks of data, then this audio blocks of data is obtained in decoding;
Step S802 judges that this audio blocks of data whether through the GZIP compression, if through overcompression, then enters step S803, if uncompressed then enters step S804;
Step S803 to use the decompression operation of GZIP through the audio blocks of data of overcompression, restores the audio initial data;
Step S804 plays the initial data of audio by the playback interface that mobile-terminal platform provides.
The picture frame reduction is the inverse process of picture frame compression.Comprise: reduction step and interframe reduction step in the frame, wherein, reduction step specifically comprises in the frame:
At first, decoding UFO file (stream), the data format (8+X) of definition during according to coding, read the data (head part of data) of 8 bytes earlier, then according to the information that comprises in these 8 bytes (type of data, the length of data etc.), read the data (body portions of data) of respective length again, constitute complete data, the data that read are kept at a buffering area (chained lists of the in store a plurality of data structures of this buffering area), and this buffering area also comprises public information and the common image head part of UFO.
Then, read the content of this buffering area, judge, if image block, judge whether compression,, then use the decompression operation of GZIP if GZIP compresses the back data through GZIP, restore the preceding image pixel data of GZIP compression, if compression then directly obtains image pixel data.With the public picture header information of image pixel data combination that obtains, play up on mobile terminal screen by the display interface that mobile-terminal platform provides.
The interframe reduction step comprises: during rendering image, simply by image overlay, restore the image display effect before transparence is handled on portable terminal.Be that image A and B are two continuous frames, when coding with the transparent B of changing into ' of B (only remain with image pixel data different with A among the B, same section has been coated with Transparent color and has erased), when playing up, show A earlier, and then stack B ', final like this display effect and B are just the same.
