Embodiment 1

[0059] figure 1 The implementation process of the method for taking pictures provided by the first embodiment of the present invention is shown, and the details are as follows:

[0060] In step S101, the current tilt angle of the mobile terminal is acquired.

[0061] In this embodiment of the present invention, when the user turns on the camera of the mobile terminal to take a picture, the mobile terminal can obtain its own current tilt angle.

[0062] An acceleration sensor is installed on the mobile terminal, and the current tilt angle of the mobile terminal is determined according to the magnitude of the component values ​​of the acceleration sensor on the three spatial axes of x, y, and z.

[0063]Specifically, the acceleration sensor is a three-axis sensor (x, y, and z three axes), which is used to measure the current acceleration of the mobile terminal. When the mobile terminal is in a horizontal stationary state, the mobile terminal is only affected by the acceleratio...

Embodiment 2

[0083] image 3 A block diagram of the specific structure of the apparatus for taking pictures provided by the second embodiment of the present invention is shown. For convenience of description, only the parts related to the embodiment of the present invention are shown. The device 3 for taking pictures may be a software unit, a hardware unit or a unit combining software and hardware built in the mobile terminal, and the device 3 for taking pictures includes: a tilt angle determination unit 31 , a crop area determination unit 32 and a display unit 33 .

[0084] Wherein, the tilt angle determination unit 31 is used to determine the current tilt angle of the mobile terminal;

[0085] The cropping area determination unit 32 is configured to determine the to-be-cropped area of ​​the first photo according to the current inclination angle determined by the inclination angle determination unit, the total length of the first photo obtained by shooting, and the total width of the firs...

Embodiment 3

[0106] Figure 4 A specific structural block diagram of the mobile terminal provided in Embodiment 3 of the present invention is shown. For convenience of description, only the parts related to the embodiment of the present invention are shown. The mobile terminal 4 may be a smart phone or a tablet computer, and includes the photographing device 3 described in the second embodiment. The photographing device 3 includes: a tilt angle determining unit 31 , a cropping area determining unit 32 and a display unit 33 .

[0107] Wherein, the tilt angle determination unit 31 is used to determine the current tilt angle of the mobile terminal;

[0108] The cropping area determination unit 32 is configured to determine the to-be-cropped area of ​​the first photo according to the current inclination angle determined by the inclination angle determination unit, the total length of the first photo obtained by shooting, and the total width of the first photo and cropping the to-be-cropped ar...

Abstract

The present invention is applicable to the technical field of mobile terminals, and provides a method and device for taking photos and a mobile terminal. The method includes: determining the current tilt angle of the mobile terminal; The length and the total width of the first photo determine the area to be cropped of the first photo and cut out the area to be cropped; copy the data of the non-cropped area in the first photo to the second photo, and display The second photo. In the present invention, when the mobile terminal is tilted, what the user sees is no longer a tilted photo but an upright photo, which overcomes the mobile terminal provided by the prior art. After holding it straight, many of the photos taken still have a slight tilt problem.

Description

technical field [0001] The present invention belongs to the technical field of mobile terminals, and in particular, relates to a method, a device and a mobile terminal for taking pictures. Background technique [0002] With the rapid development of mobile terminals, work that was previously required on PCs, notebook computers, and cameras can also be easily implemented on mobile terminals. [0003] However, in the process of implementing the present invention, the inventor found that the mobile terminal provided by the prior art has at least the following problems: [0004] In the process of using the mobile terminal to take pictures, many users correct the angle of the mobile terminal, hold the mobile terminal vertically, and hope to take a horizontal picture. However, due to the feeling, many photos taken will still appear slightly tilted (of course, the situation of deliberately tilted shooting is not included). SUMMARY OF THE INVENTION [0005] In view of this, embod...
