Being described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of same or like function from start to finish。The embodiment described below with reference to accompanying drawing is illustrative of, it is intended to is used for explaining the present invention, and is not considered as limiting the invention。
Below with reference to the accompanying drawings the control method of screen, device and mobile terminal in the mobile terminal of the embodiment of the present invention are described。
Fig. 1 is the flow chart of the control method of screen in mobile terminal according to an embodiment of the invention。As it is shown in figure 1, the control method of screen in the mobile terminal of the embodiment of the present invention, comprise the following steps:
S1, obtains the first image that mobile terminal shoot in the very first time and the second image shot in the second time respectively。
In one embodiment of the invention, obtain the first image and the second image after the screen of mobile terminal is lighted or in continuing to light, and after screen goes out or closes, delete the first image and the second image。
Specifically, opening screen automatic rotation function user, when screen is lighted, opening timing device prepares to take pictures, with the first image obtaining very first time shooting and the second image shot in the second time。Wherein, mobile terminal when taking pictures before and after the shooting gap of two images (the first image and the second image) can be several seconds, and can automatically trigger。
S2, the direction of rotation according to the first image and the second image discriminating mobile terminal。
In one embodiment of the invention, as in figure 2 it is shown, S2 specifically includes:
S21, extracts the first profile data in the first image, and extracts the second outline data in the second image。
Specifically, after getting the first image and the second image, it is necessary to image zooming-out outline data, the outline data extracted is used to judge the valid data whether image rotates。For example, it is possible to the first profile data extracted by image processing software in the first image, L1, L2, L3, L4, L5, L6 as shown in Figure 3, and extract the second outline data in the second image, L1, L2, L3, L4, L5, L6 as shown in Figure 4。
S22, differentiates the direction of rotation of mobile terminal according to the first profile data and the second outline data。
In one embodiment of the invention, differentiate the direction of rotation of mobile terminal according to the first profile data and the second outline data, particularly as follows: the direction of rotation according to the direction of the first profile data and the discriminating direction mobile terminal of the second outline data。
Specifically, the first profile data and the second outline data are contrasted, select relevant data item, such as select the data item that length is identical, such as L6, then obtain L6 position in the first image and the second image respectively, and then determine the direction of rotation of mobile terminal according to the change of L6 position。
S3, the screen controlling mobile terminal according to the direction of rotation of mobile terminal rotates。
Specifically, it determines after going out the direction of rotation of mobile terminal, just corresponding rotation can be carried out according to the screen of the direction of rotation control mobile terminal of mobile terminal。
