For being illustrated more clearly in the solution of the present invention, first Quick Response Code is described below:

Quick Response Code is by changing text to be encoded to obtain; Such as, according to the coding rule of Quick Response Code, can be the Quick Response Code represented with image format using a string text string generation as text to be encoded.When a recognition of devices Quick Response Code, Quick Response Code is divided into multiple color lump by it, and by judging that each color lump is dark block or light block, carrys out decode two dimensional codes, thus the Quick Response Code showed with image format is reduced to above-mentioned text to be encoded.

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

Preferably, a point in dot matrix can cover the whole color lump belonging to it, and as in Fig. 8, stain and white point cover whole color lump respectively; Or the area of a point in dot matrix is less than the area of color lump belonging to it, and as in Fig. 6 c, stain and white point are all only positioned at the core of color lump.Wherein, when the area of the point of in dot matrix is less than the area of color lump belonging to it, can the gray scale of the point comprehensively in color lump and other parts beyond point, determine the gray scale of this color lump, thus judge that this color lump belongs to dark block or light block, as in Fig. 6 c, the gray scale of the background in the gray scale of the point of star and this color lump except point can be similar in a comprehensive color lump, determine the gray scale of this color lump; Wherein, other parts in color lump except point, be the secondary coloured moiety of this color lump, preferably, this secondary coloured moiety is transparent.It should be noted that, because background color is white, therefore the white point in Fig. 6 a, Fig. 6 b and Fig. 6 c cannot observe, but it is actual is exist, such as, the second image shown in Fig. 7 is by being carried out merging obtaining by the second image shown in the first image as shown in Figure 5 and Fig. 6 c, can observing white point from Fig. 7.

As a kind of preferred form of Quick Response Code, Quick Response Code also can comprise position sensing region, this position sensing region is used for the equipment location Quick Response Code for decode two dimensional codes, and such as, the figure that the dotted line frame A in Quick Response Code shown in Fig. 9 comprises is one of three position sensing regions in this Quick Response Code.

In step s 2, computer equipment, according to dot matrix discrimination, determines the predetermined pattern being applicable to described first image.

Preferably, computer equipment, by judging whether described dot matrix discrimination exceedes predetermined discrimination threshold value, determines whether a predetermined pattern is applicable to the first image.

Such as, if dot matrix discrimination exceedes predetermined discrimination threshold value, then determine that this predetermined pattern is applicable to the first image; If dot matrix discrimination is lower than predetermined discrimination threshold value, then determine that this predetermined pattern is not suitable for shown first image.

Such as, predetermined discrimination threshold value is 80%, and the dot matrix discrimination obtained in step sl is 90%, then determine that this pattern is applicable to the first image.

It should be noted that, above-mentioned citing is only and technical scheme of the present invention is described better, but not limitation of the present invention, those skilled in the art should understand that, any according to described dot matrix discrimination, determine the implementation of the predetermined pattern being applicable to described first image, all should be within the scope of the present invention.

It should be noted that, computer equipment at execution step S1 after obtaining the dot matrix discrimination of all predetermined pattern, then can perform step S2, thus from least one predetermined pattern, select one or more predetermined pattern being applicable to the first image.Or computer equipment often performs after a step S11 and S12 obtains the dot matrix discrimination of a predetermined pattern, performs a step S2 immediately, judges whether this predetermined pattern is applicable to the first image.And, after judging that this predetermined pattern is applicable to the first image, computer equipment can no longer continue to judge whether other predetermined pattern are applicable to the first image, or, computer equipment performs step S11 and step S12 again to obtain the dot matrix discrimination of next predetermined pattern, and perform step S2 thus judge whether it is applicable to the first image, so repeats, until judgement operation is executed to all predetermined pattern; After judging that this predetermined pattern is not suitable for the first image, computer equipment performs step S11 and step S12 again to obtain the dot matrix discrimination of next predetermined pattern, and perform step S2 thus judge whether it is applicable to the first image, repetition like this, until execute judgement operation to all predetermined pattern or obtained being applicable to the predetermined pattern of the first image.
