Description

A kind of date storage method based on RGB coloud coding

Technical field

The present invention relates to utilize RGB primaries principle, adopt chpn coding techniques, the binary coding of color is corresponding with fileinfo binary coding, thus realize the method for storage file content.

Background technology

Computer system data is taked binary format at present, only has " 0 " and " 1 " two kinds of forms, and one " 0 " or " 1 " account for one " position ", it is the storage cell of storer minimum, be called bit (bit), 8 bits are called a byte (byte), equal 8 binary digits.Common each numeral, English alphabet will account for a byte, and a Chinese character will account for two bytes.Currently be stored in data on the media such as floppy disk, CD, DVD, hard disk, flash memory, USB flash disk, CF card and all take this pattern to carry out access.

In computer system, any color of occurring in nature all can be added and mix in different ratios by R, G, B three primary colours, and the color of mixing when three primary color components are all 0 is black light; The color of mixing when three primary colours component is all 255 is white light.When adjusting, by the arbitrary coefficient in three chroma brightness coefficient r, g, b, all can change the colour of color F, also change the coding of F.Each color F is corresponding unique r, g, b coefficient, thereby has unique coding.When file binary coding is corresponding with different colours F coding, every kind of color represents certain binary sequence, and some color alignment together, just can realize the object of log file data.

Summary of the invention

The present invention proposes a kind of based on RGB coloredcoded data storage means: adopt chpn coding techniques, according to certain rule, the color of i layer is appointed as , on any one the pixel P on i layer, can only there be two kinds of color state, the one, , it is " 1 " that representative has color, corresponding binary coding, its color coding is

; The 2nd,

, be black, corresponding binary coding is " 0 ".The color F of any point on image, is that the state combination in any by each layer of color is formed by stacking, and counts

.The coding of color F can be corresponding with the binary coding of corresponding data content, thereby reach the object of record data.

For achieving the above object, the scheme of taking is in the present invention:

1) color assignment standard.Suppose that we will take N layer data to store data, consider that every kind of color is comprised of R, G, tri-color components of B.Selected necessary following two conditions that meet of color of every one deck: the one, the coding of each layer of color must be different, and the 2nd, each layer of color that color combination in any mode superposes and makes new advances, different.So we adopt M position coloud coding to represent, M bit binary data is described, and M is greater than or equals N.

We select the binary-coded rule of color as follows:

The 1st kind of color: 00 ... 000 ... 001

The 2nd kind of color: 00 ... 000 ... 010

The 3rd kind of color: 00 ... 000 ... 100

……

N-1 kind color: 00 ... 001 ... 000

N kind color: 00 ... 010 ... 000

N+1 kind color: 00 ... 100 ... 000

……

M-1 kind color: 01 ... 000 ... 000

M kind color: 10 ... 000 ... 000

For storing every one deck of data, can choose a kind of color as this layer from above colour sequential, or when N is less than M, select several color combination of above sequence to form, but in above-mentioned sequence, color only can be used once.Because each pixel P of every one deck can only have two states, a kind of is complete " 0 " black, and another kind is exactly the selected look of this layer, respectively corresponding coding " 0 " and " 1 ".

Take above principle, the coding of the color of N layer is added arbitrarily, can not produce carry, so different array modes can only generate different codings, and then presents different colors.Above colour sequential can be upset or adjust, but every kind of color can only occur once.

2) file on computing machine, is all with binary mode, to be recorded on the media such as disk, internal memory, CD, on file symbol, character, numeral, Chinese character etc. all convert " 0 " to or record " 1 ".By computer documents, with N position, binary sequence is cut apart, every N binary digit is as a unit, and not enough N position is with 0 polishing, and the coding of the just corresponding color in the unit of each N position, presents a kind of color of correspondence with it like this.

3) a pixel P in each unit correspondence image, when some unit are arranged together, has just formed a width N position coloured image, has so just realized computer documents information recording on coloured image.

The invention has the beneficial effects as follows: utilize coloured image, by the binary coding of different colours, to enter mechanism corresponding with document content information two, thereby realize, fileinfo is recorded in coloured image.The present invention can export with color printer, also can realize the convenient propagation of data by modes such as e-files, is widely used in the fields such as data storage and propagation, advertisement, authentification of message, data encryption, E-Payment.

Embodiment

Transparency component, and RGB component still only accounts for 24), M equals 24. our hypothesis and will, by the file taking up room on computer disk as 15k size, be stored in a width coloured image.

The color value sequence of 24 true color is:

1：00000000 00000000 00000001

2：00000000 00000000 00000010

……

23：01000000 00000000 00000000

24：10000000 00000000 00000000

Example one, employing 24 layer data pictures storages

Adopt 24 layer data storages, N equals 24, any one color in the desirable above colour sequential of color of every one deck, and can only choose unique a kind of color.Its array mode can only have a kind of.

First, we need to calculate the size of this file required image of storage.

15k is converted to bit unit:

15kХ1024bit/k=15360bit

Owing to having adopted 24 layer data storages, the color that pixel P represents is comprehensively formed by stacking by 24 layers of different colours, and a pixel can record the long data of 24 bit, so the number of pixels that will store the large small documents of 15k and at least need is:

15360bit/24bit=640 pixel

So we can adopt 24 true color images of rectangle of 20*32 pixel to store.

The second, open the above file that will store, the binary sequence of this document is cut apart by one group of every 24 bit, correspondence pixel in image lists successively, and each pixel records the data of 24 bits.So just by the content record of file in 24 layer data of 24 true color of a width 20*32 pixel.

Example two, employing 8 layer data pictures storages

Adopt 8 layer data storages, N equals 8, any one color in the desirable above colour sequential of color of every one deck, and can only choose unique a kind of color.Its array mode has 735471(

) plant.

First, we need to calculate the size of this file required image of storage.

15k is converted to bit unit:

15kХ1024bit/k=15360bit

Owing to having adopted 8 layer data storages, the color that pixel P represents is comprehensively formed by stacking by 8 layers of different colours, a pixel can record the long data of 8 bit, because 24 coloured images have 24, thus not enough 16 layers can take number of pixels that the large small documents of " 0 " polishing occupy-place storage 15k at least needs as:

15360bit/8bit=1920 pixel

So we can adopt 24 true color images of rectangle of 60*32 pixel to store.

Second, open the above file that will store, the binary sequence of this document is cut apart by one group of every 8 bit, increase in the back 16 " 0 " and carry out occupy-place simultaneously, form a unit successively corresponding in image pixel list, each pixel records the data of 8 bits.So just by the content record of file in 8 layer data of 24 true color of a width 60*32 pixel.

The present invention utilizes RGB coloured image hierarchical coding technology, file is divided into a pair of ordered series of numbers according to the figure place of color, the binary coding of the corresponding color of each element, is recorded in fileinfo in coloured image thereby realize, and has realized the visual storage of file.
