201,201 .., 210；... the coordinate information recorded in the rectangular element in the 7th row is respectively 701,702 ..., and 710.For example,
If the coordinate information recorded in a rectangular element is 101, understand, the rectangular element is in the position rectangular image 32
The rectangular element of 1st row the 1st row, so as to know the position of the rectangular element on a display screen.
It should be noted that the seat in the size or quantity and rectangular element of rectangular element in the rectangular image of position
It can be systemic presupposition to mark information, can also be temporarily self-defined.That is, the coordinate information in a coordinate unit is with being somebody's turn to do
Corresponding relation between the position of coordinate unit on a display screen can be systemic presupposition, can also be temporarily customized.This
Inventive embodiments are not construed as limiting to this, as long as ensureing, it is known that the coordinate information in coordinate unit, so that it may be inferred to the coordinate unit
Position on a display screen.
It should be understood that adjacent four rectangular elements in the rectangular image of position have a crosspoint, this is intersected herein
Point is designated as rectangular cross point.
Specifically, as shown in figure 3, coordinate information is respectively 408,508,409 and 509 in position rectangular mesh image 32
4 adjacent rectangle units have a rectangular cross point 34.
It should be understood that according to the coordinate information in the rectangular image of position in each rectangular element, can also infer that correspondence square
The coordinate in shape crosspoint.
Alternatively, the form of expression of the coordinate information in rectangular element can be digital (as shown in Figure 3) or its
His feasible mark, the embodiment of the present invention is not construed as limiting to this.
Specifically, in step 22, the collection image of the fingerprint sensor of acquisition at least includes in the rectangular image of position
One complete rectangular element.
Specifically, by taking the position rectangular image 32 shown in Fig. 3 as an example, and the length and width point of image acquisition region are assumed
Not Wei L, W, exemplified by the length of each rectangular element and width are respectively L/2, W/2 in grid image, the collection image such as Fig. 4
(a) or shown in Fig. 4 (b).
It is complete in the collection image to include 4 rectangular elements in position rectangular image 32, this 4 as shown in Fig. 4 (a)
There is coordinate information 408,409,508 and 509 respectively in rectangular element.
As shown in Fig. 4 (b), 1 rectangular element in the position rectangular image 32 is completely included in the collection image, this
There is coordinate information 408 in rectangular element.
Specifically, in step 23, image recognition processing is carried out to the collection image, identification obtains wrapping in the collection image
The coordinate information having in the complete rectangular element included；According to the coordinate information having in the rectangular element, display screen is determined

Under the coordinate system of display screen, the coordinate of the central point of the collection image.
Alternatively, as an alternative embodiment, have in the complete rectangular element for directly including the collection image
The corresponding coordinate of some coordinate informations is defined as the centre coordinate that the fingerprint points out pattern.
Specifically, it is assumed that shown in the collection image such as Fig. 4 (b), in the complete rectangular element that the collection image includes
The coordinate information having is 408, for example, coordinate information 408 represents the coordinate (7L/4,15W/4) on display screen, then by coordinate
(7L/4,15W/4) is defined as the centre coordinate that the fingerprint points out pattern.
For example, determining that the fingerprint points out the size of pattern according to the size of image acquisition region.Carried it should be understood that obtaining fingerprint
After the centre coordinate and size of diagram case, it is possible to obtain the position of fingerprint prompting pattern on a display screen.
Alternatively, as another alternative embodiment, the collection image also at least includes one of the location matrix image
Rectangular cross point (such as the rectangular cross point 34 shown in Fig. 3), the rectangular cross point represents adjacent in the location matrix image
Crosspoint common to four rectangular elements；Wherein, the complete rectangular element that step 23 includes according to the collection image is had
Some coordinate informations, determine coordinate of the central point of the collection image in the display screen, including：Calculate in the collection image
The distance between rectangular cross point that heart point includes with the collection image；Included according to the distance and the collection image
The coordinate information that complete rectangular element has, calculates coordinate of the central point of the collection image in the display screen.
Specifically, first, under the coordinate system of the collection image, the central point and the collection image of the collection image are calculated
The distance between rectangular cross point included.Then, in the complete rectangular element included according to the collection image
The coordinate information having, can be inferred that the coordinate of the rectangular cross point in the display screen.Finally, according to the rectangular cross point
Coordinate in the display screen, and calculate the distance between the obtained rectangular cross point and central point of the collection image,
Calculate coordinate of the central point for obtaining the collection image in the display screen.
