Embodiment 1

[0032] refer to figure 1 , which shows a flow chart of a method for automatically adjusting a camera according to Embodiment 1 of the present invention, which may specifically include the following steps:

[0033] Step 101, acquire a frame of preview image captured by a camera for a shooting scene.

[0034] In practical applications, when the user enters the camera photo mode of the mobile terminal, the camera photo mode will enter the photo preview mode, in which the subject will be focused, and the exposure and other photo data will be adjusted according to the current shooting environment, so After the user confirms the object to be photographed, the camera will automatically acquire a frame of image in the current preview mode, cache it in the mobile terminal, and enter the next step.

[0035] Step 102, determining the target object in the photo preview interface.

[0036] In practical applications, when the mobile terminal is used, when the user turns on the camera func...

Embodiment 2

[0045] refer to figure 2, which shows a flow chart of a method for automatically adjusting a camera according to Embodiment 2 of the present invention, which may specifically include the following steps:

[0046] Step 201, acquire a frame of preview image captured by a camera for a shooting scene.

[0047] This step is the same as step 101 in Embodiment 1, and will not be described in detail again.

[0048] Step 202, performing face recognition in the photo preview interface.

[0049] In practical applications, the cameras of mobile terminals can be equipped with metering systems for surface metering, spot metering, and bracket metering, as well as 5-point and 9-segment focusing systems. , lock the position of the face in the preview screen, and actively take the face as the subject of the shooting, set the accurate focus and exposure to ensure that the face is clear and the exposure is accurate, and when there are multiple people in the preview screen The face recognition...

Embodiment 3

[0063] refer to image 3 , which shows a flow chart of a method for automatically adjusting a camera according to Embodiment 3 of the present invention, which may specifically include the following steps:

[0064] Step 301, acquire a frame of preview image captured by a camera for a shooting scene.

[0065] This step is the same as step 201 in Embodiment 1, and will not be described in detail again.

[0066] Step 302, performing human outline recognition in the photo preview interface.

[0067] In practical applications, humanoid recognition usually includes the process of target detection, boundary extraction, and humanoid target recognition. Target detection can be done by detecting frame difference, background difference, etc. When the mobile terminal processes the preview screen and recognizes After the human-shaped target, the camera of the mobile terminal can focus on the human-shaped target and adjust shooting parameters such as exposure to make the human-shaped targe...

Abstract

The embodiment of the invention provides a method for automatically adjusting a camera, and a mobile terminal, relating to the technical field of communication. The method comprises the following steps of: obtaining a one-frame preview image acquired by the camera from a shooting scene; determining a target object in a shooting preview interface; determining a target position, to which the target object moves, in the shooting preview interface; and controlling the camera to rotate till the target object is positioned in the target position. According to the method for automatically adjusting the camera, and the mobile terminal provided in the embodiment of the invention, when a user takes a picture, the camera can automatically rotate according to user selection; the focusing mode is changed; therefore, a shot object is in a user satisfactory shooting scene; no-dead-angle shooting can be carried out when the user takes a picture by using the mobile terminal; the shooting experience of the user is improved; and the problem that the shot object cannot be adjusted to a satisfactory position in the shooting preview picture due to the fact that the shooting scene is limited when the user takes a picture can be solved.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a method for automatically adjusting a camera and a mobile terminal. Background technique [0002] With the rapid development of electronic technology, electronic equipment is widely used in daily life. The most popular application is to install cameras on mobile terminals such as mobile phones. Shooting, the camera technology configured in mobile terminals is becoming more and more advanced, which can meet people's high requirements for photo or video quality. In addition, the cameras in mobile terminals also have high-quality sensors, high color bits, and automatic focus. The high-quality technology of professional digital camera enables users to get high-quality shooting experience. [0003] In many cases, when a user uses a mobile terminal to take pictures, the optional angle is limited by the position of the human body when the user holds the mobile terminal to tak...
