Abstract
The invention discloses a picture processing method and a picture displaying method and a picture displaying device for an embedded terminal. The picture processing method comprises the following steps of: analyzing a display effect of a picture and thus acquiring the characteristic value of the picture; judging whether the picture meets the requirements of the specified display contents or not according to the characteristic value of the picture; splicing the picture which meets the requirements of the specified display contents and removing redundancy information from the picture; and packaging the picture to generate a picture data packet according to the sliced picture contents and related information which are acquired, wherein the picture data packet comprises the selected spliced picture contents and header information. By splicing and packaging the picture which meets the requirements of the specified display contents by the method, the redundancy information is eliminated from the picture, storage space occupied by the picture is greatly reduced, and the method adapts to the occasion that flash and memory resources in an embedded system are limited and can be widely applied to the field of embedded systems.
Description
Technical field
The present invention relates to picture treatment technology and embedded system picture display technique, especially a kind of image processing method of conserve memory resource and the image display method of embedded system and device.
Background technology
Along with rapid development of multimedia, graphics has been widely used in every field such as animation, visualization in scientific computing, CAD/CAM, video display amusement.Because flash resource and memory source are limited in the embedded product, and the storage of picture is had higher requirement.
In built-in field, with reference to Fig. 1, traditional image processing method is: need the picture of demonstration through picture editor (like photoshop etc.) instrument mapping generations; Be placed on this picture among the flash then and assigned catalogue and figure title; When needs show this image content, be loaded into picture in the internal memory and carry out picture decoding, the image content that generation can be used to fill; In the time of need being filled on the screen, be filled into decoded picture on the screen.But there are following shortcomings and deficiencies in conventional solution:
1. the picture full content all need be placed among the flash, comprises the bulk redundancy information that the picture inside of specific display effect comprises, and causes the waste of flash resource like this;
2. when the picture of specific display effect is decoded, need decode the picture full content that comprises bulk redundancy information, efficient is lower;
3. in the picture of specific display effect when decoding, need be loaded into the picture full content that comprises bulk redundancy information in the internal memory and decode, and decoded content also need all store in the internal memory, bigger waste valuable memory source;
4. in the picture filling process, if the scope that picture size and picture are filled is inconsistent, need the stretching picture, drawing effect and picture original effect there are differences, and influence display effect, phenomenons such as color range particularly can occur;
5. each picture is only supported a kind of picture format; Because the different-format picture is different according to the content of picture; Compression factor is different with effect, and the displaying contents of zones of different possibly more meet the requirement of different format pictures in the picture, but can only select a kind of picture format to use;
6. be placed in the product picture and can be seen that fully can arbitrarily be replaced or revise, image content does not have disguise by other people;
7. during if desired through network upgrade or update software picture resource,, can waste Internet resources, and update time is longer because picture is bigger.
Above-mentioned technological deficiency has hindered the lifting of innovation of built-in field picture Treatment Technology and user experience.
Summary of the invention
The technical matters that the present invention will solve is: provide a kind of remarkable saving picture to take the image processing method of storage resources.
The built-in terminal image display method that the present invention also provides a kind of and decodes fast, display effect is good.

In order to solve the problems of the technologies described above, the technical scheme that the present invention adopted is:
A kind of image processing method may further comprise the steps:
A. analyze the display effect of picture, obtain the eigenwert of this picture;
B. according to the eigenwert of picture, judge whether this picture meets the specific display requirement;
C. the picture that meets the specific display requirement is carried out slicing treatment, remove the redundant information in the picture;
D. according to the picture that obtains after slicing treatment section content and relevant information, to picture processings of packing, generate the image data bag, said image data bag comprises the picture of choosing cut into slices content and header packet information.
Further as preferred embodiment, said eigenwert is the picture colouring information repeated and redundant value that meets minimum appointed area on the picture, and it is that said eigenwert is more than or equal to predetermined threshold that said specific display requires.
Further as preferred embodiment, the said header packet information of step D comprises the picture format of section pattern, slice numbers, each picture section, the content-length of each picture section.
Further as preferred embodiment, the plurality of picture form is supported in the picture section after the slicing treatment, comprises JPG, PNG, GIF picture format.
A kind of built-in terminal image display method may further comprise the steps:
The header packet information of the image data bag that F. image processing method of the present invention is generated is resolved, and obtains the relevant information of each picture section, said relevant information comprise the length of picture section, highly, width and picture format;
G. read the section of each picture successively and load and decode, in zone to be filled, fill successively;
H. judge whether zone to be filled also exists remaining area, if also there is remaining area, the section of control picture is expanded filling with the mode of tiling, with the former image content of complete demonstration.
Further, before execution in step F, also comprise as improving:
E. judge the image data bag whether pending picture generates for image processing method of the present invention, if " being " execution in step F then,, picture is decoded and filled if " deny " then pressed conventional processing.
A kind of built-in terminal image display apparatus comprises:
Resolution unit is resolved the image data bag that image processing method of the present invention generates, obtaining the relevant information of each picture section, said relevant information comprise the length of picture section, highly, width and picture format;
