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

Embodiments of the present invention provide a method for automatically adjusting a camera and a mobile terminal, and relate to the technical field of communications. The method includes: acquiring a frame of preview image collected by the camera on the shooting scene; determining the target object in the photo preview interface; determining the target position to be moved to by the target object in the photo preview interface; controlling the camera Rotate until the target object is at the target position. The embodiment of the present invention provides a method for automatically adjusting the camera and the mobile terminal. When the user takes a picture, the camera can be automatically rotated according to the user's choice, and the focus mode can be changed so that the shooting object is placed in the shooting scene that the user is satisfied with. When the user uses the mobile terminal to shoot, he can shoot without dead angles, which improves the user's shooting experience. Solve the problem that the user cannot adjust the subject to the satisfactory position of the shooting preview screen due to the limited shooting scene when shooting.

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...
