Embodiment Construction

[0043] see figure 1 , animation compression method of the present invention is carried out according to the following steps successively:

[0044] 110) converting all graphics in the animation file into low-level graphics;

[0045] 120) Covering the same part in the low-level graphics;

[0046] 130) Cutting the masked graphics and retaining their effective parts;

[0047] 140) Generate a corresponding palette according to the characteristics of the output device

[0048] 150) According to the color scale of the effective part, the animation compressed file is obtained through dictionary compression.

[0049] An animation file is composed of a series of graphics with similar content, but the graphics that make up the animation are often pictures in a storage format such as true color, such as graphics with 24bit color or higher. The file size is too large, and it is not suitable for computer configurations Play in lower portable electronic devices. Therefore, it is first n...

Abstract

This invention relates to a method for quick compression and de-compression of a high compression ratio multi-plane among which, the compression method includes the following steps: transferring all drawings in the multi-plane document to low color stage drawings, shielding the same part in drawings, cutting the shielded drawings to maintain the effective part, generating corresponding tone plate according to characters of the output equipments, acquiring compressed documents by dictionary compression in terms of the color stage of the effective part. The de-compression method includes: de-compressing the multi-plane compression documents according to compression dictionary to get de-compressed drawings, synthesizing it to complete drawing in terms of the shield way, determining the algorithm of restoring the complete drawing to initial color stage based on the tone plate of the output device, acquiring the current drawing in accordance of its converted color and playing the current drawing by sticking the picture.

Description

1. Technical field [0001] The invention relates to a graphic compression and decompression method, in particular to a fast animation compression and decompression method with a high compression ratio. 2. Background technology [0002] Currently, various portable electronic devices are widely used in our daily life, such as mobile phones, PDAs, MMVs, palmtop computers and the like. With the continuous development of multimedia technology, due to its various acousto-optic effects, playing these various multimedia information on the above-mentioned portable electronic device is a common expectation of the majority of users. [0003] Animation files are generally large, and in order to be suitable for playing on portable electronic devices, they usually need to be compressed. Existing animation compression methods fall into two categories: [0004] 1. Compress the content of each frame separately, and then decompress and display it frame by frame during playback. Such methods...
