To be illustrated more clearly that the solution of the present invention, first Quick Response Code is illustrated below：

Quick Response Code can be obtained by changing text to be encoded；For example, according to the coding rule of Quick Response Code, it can will be used as and treat A string of text string generations of coding text are the Quick Response Code represented with image format.When an equipment identifies Quick Response Code, it will Quick Response Code is divided into multiple color lumps, and by judging each color lump for dark block or light block, to decode Quick Response Code, so that will Above-mentioned text to be encoded is reduced to the Quick Response Code that image format shows.

Wherein, Quick Response Code includes Two dimensional Distribution dot matrix, and each point in dot matrix belongs to a color lump, Quick Response Code shown in Fig. 9 In the dot matrix that include of dotted line frame B be Two dimensional Distribution dot matrix an example.It should be noted that in Two dimensional Distribution dot matrix The appellation of " point ", is mainly used for more compactly representing a color main coloured moiety in the block, and should not be construed as main to this The restriction of the shape of coloured moiety.In fact, the form of the main coloured moiety can arbitrarily change, such as can be Fig. 6 a and Star and circle shown in Fig. 6 b, can also be other shapes, such as bear's paw, the flower-shape being made of 4 independent hemp nettle valves.

Preferably, a point in dot matrix can cover the whole color lump belonging to it, and in Fig. 8, stain and white point cover respectively Cover whole color lump；Alternatively, the area of a point in dot matrix is less than the area of its affiliated color lump, in Fig. 6 c, stain and white point It is only located at the core of color lump.Wherein, can be comprehensive when the area of a point in dot matrix is less than the area of its affiliated color lump The gray scale of the other parts beyond color point in the block and point is closed, to determine the gray scale of the color lump, so as to judge that the color lump belongs to deep Color lump or light block, in Fig. 6 c, can integrate the gray scale for the point that star is similar in a color lump and the back of the body in the color lump in addition to point The gray scale of scape, to determine the gray scale of the color lump；Wherein, the other parts in color lump in addition to point, for the secondary colour developing of the color lump Part, it is preferable that the secondary coloured moiety is transparent.It should be noted that due to background color for white, therefore Fig. 6 a, Fig. 6 b and White point in Fig. 6 c can not observe, but it is really existing, be by will be such as figure for example, the second image shown in Fig. 7 The second image shown in the first image and Fig. 6 c shown in 5 is merged to obtain, and white point can be observed from Fig. 7.

As a kind of preferred form of Quick Response Code, Quick Response Code may also include position sensing region, which uses Quick Response Code is positioned in the equipment for decoding Quick Response Code, for example, the figure that the dotted line frame A in Quick Response Code shown in Fig. 9 is included is should One of three position sensing regions in Quick Response Code.

Step S1 and step S2 is included according to the method for the present embodiment.In step sl, computer equipment is based at least one Each predetermined pattern in kind predetermined pattern performs step S11 and step S12.

In step s 11, computer equipment obtains what is generated based on text to be encoded and currently processed predetermined pattern The half-tone information of Two dimensional Distribution dot matrix in Quick Response Code.

Preferably, a predetermined pattern at least provides following information：

1）The shape at Two dimensional Distribution dot matrix midpoint.For example, the shape of the point of Two dimensional Distribution dot matrix is such as star in Fig. 6 a, again For example, the shape at Two dimensional Distribution dot matrix midpoint is as being circle in Fig. 6 b.In addition, the shape of each point also may be used in Two dimensional Distribution dot matrix The shape of difference, such as white point and stain can difference.

2）In the case that the area of point in Two dimensional Distribution dot matrix is less than the area of color lump belonging to the point, predetermined pattern is also Including the part in a color lump in addition to point, i.e., the transparency of secondary coloured moiety；Preferably, the transparency of dark block with it is shallow The transparency of color lump can be different.For example, the transparency of the part in the color lump of Fig. 6 a in addition to point is 100%, therefore can be seen that Part in addition to point is transparent, does not interfere with the color that the first image is showed；In another example Two dimensional Distribution point in Fig. 6 c The transparency of the dark block of battle array is 25%, it can be seen that in a dark block, in addition to point, secondary coloured moiety also shows Certain black.

It should be noted that the above-mentioned examples are merely illustrative of the technical solutions of the present invention, rather than the limit to the present invention System, it should be appreciated by those skilled in the art that the predetermined pattern of any form of expression that can be used in regulation Quick Response Code, should all include Within the scope of the invention.

It should be further noted that although Fig. 6 a to the Two dimensional Distribution dot matrix shown in 6c close to rectangle, but this area Technical staff will be understood that Two dimensional Distribution dot matrix can behave as any shape, such as pentagon, triangle, star, irregular figure Deng；Also, although Fig. 6 a include position sensing region to the Quick Response Code shown in 6c, but those skilled in the art should be able to manage Solution, Quick Response Code can not include the position sensing region yet.

Specifically, computer equipment obtains the two dimension in the Quick Response Code generated based on text to be encoded and the predetermined pattern The mode for being distributed the half-tone information of dot matrix includes but not limited to：
