[0033] see Figure 5 , the first embodiment of the present application provides a photographing method. The shooting method is used to take pictures in the current shooting mode when shooting after moving the terminal according to the current shooting mode of the target object. In a specific embodiment, the shooting method is applied as Figure 13 The photographing device shown and the mobile terminal 500 corresponding to the photographing device 400 ( Figure 14 , Figure 15 , Figure 16 ), the mobile terminal is provided with a camera 510. The above-mentioned photographing method may specifically include the following steps:

[0034] Step S110: Obtain an image of the target object through the camera.

[0035] When the mobile terminal is in the shooting mode of taking pictures or videos with the camera turned on, in order to determine whether the mobile terminal should be in the landscape shooting mode or the portrait shooting mode, it can be judged according to the ima...

[0044] An embodiment of the present application provides a shooting method, which mainly uses a human face as a target object to determine a current shooting mode. Since when the mobile terminal is in a non-horizontal state, the posture sensor can be used to determine whether the screen is in landscape or portrait mode. Therefore, this embodiment of the present application can be mainly used to determine the current shooting mode of the mobile terminal in the horizontal state. Specifically, see Figure 6 , the method includes:

[0045] Step S210: judging whether the mobile terminal is currently in a horizontal state or a vertical state according to the posture of the mobile terminal. If it is in the horizontal state, execute step S220; if it is in the vertical state, execute step S250.

[0046] When the camera is turned on, the attitude of the mobile terminal can be determined. Specifically, the attitude sensor of the mobile terminal can be used for determination. The specif...

[0065] The embodiment of the present application provides a specific implementation process when shooting by the aforementioned shooting method. In the embodiment of this application, determine the coordinate system of the mobile phone, assuming that the mobile phone is placed in its default direction as shown in Figure 7, the X axis of the mobile phone coordinate system is horizontally pointing to the right, the Y axis is vertically upward, and the Z axis is pointing Outside the front of the screen, that is, the back of the screen is a negative value of Z.

[0066] When the user uses the mobile phone and the mobile phone moves or rotates, the coordinate axes in the mobile phone coordinate system will not change, that is, they follow the mobile phone. After the mobile phone sends motion or rotation, you can determine the change angle of each coordinate axis when the mobile phone coordinate system is relative to the default direction. Figure 12 It is a schematic diagram of th...

Abstract

The embodiment of the invention discloses a shooting method and apparatus, a mobile terminal and a storage medium, and relates to the technical field of mobile terminals. The method comprises the following steps: obtaining a target object image through a camera; determining whether a current shooting mode is a horizontal screen mode or a vertical screen mode according to a position relationship between a target object in the target object image and the mobile terminal; and when a shooting instruction is received, performing shooting by using the determined current shooting mode. By adoption ofthe scheme, the situation that whether the mobile terminal corresponds to a horizontal screen state or a vertical screen state cannot be determined through a posture sensor is effectively handled, and the user shooting experience is improved.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, and more specifically, to a photographing method, device, mobile terminal and storage medium. Background technique [0002] With the continuous development of mobile terminals, their functions are becoming more and more abundant, and taking pictures is one of them. When taking pictures through the mobile terminal, it is usually necessary to determine the posture of the mobile terminal according to the built-in gyroscope or acceleration sensor of the mobile terminal, so as to determine whether to shoot in landscape mode or portrait mode. However, the gyroscope or the acceleration cannot effectively distinguish the attitude of the mobile terminal in some cases, therefore, it is impossible to determine which shooting state should be used for shooting, which affects the user's shooting experience. Contents of the invention [0003] In view of the above problems, the present appl...
