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 , in the process of the camera capturing images of the shooting scene, controlling the camera to focus on the captured faces.

[0034] In practical applications, when the mobile terminal is used, when the user turns on the camera function, especially during the self-portrait process, the mobile terminal camera uses the face recognition function to focus on the face. At present, most mobile terminal cameras can be equipped with surface metering, spot metering, bracket metering metering systems, and 5-point and 9-segment focusing systems. By identifying feature information such as eyes and mouth in the shooting preview screen, 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...

Embodiment 2

[0051] refer to figure 2 , shows a flow chart of automatically adjusting the camera according to Embodiment 2 of the present invention, which may specifically include the following steps:

[0052] Step 201 , in the process of the camera capturing images of the shooting scene, controlling the camera to focus on the captured faces.

[0053] This step is the same as step 101 in Embodiment 1, and will not be described in detail again.

[0054] Step 202. Based on the focusing data of the camera, calculate a first distance and a second distance between the camera and the collected face.

[0055] In this embodiment of the present invention, according to step 102 in Embodiment 1, Figure 1A and Figure 1B , through face autofocus, the camera can recognize the contour of the face. According to the upper boundary point and the lower boundary point of the face, it can be the top of the head and the lower edge of the chin. Through the focus data of these two points, and the formula ( ...

Embodiment 3

[0077] refer to image 3 , which shows a flow chart of automatically adjusting the camera according to Embodiment 3 of the present invention, which may specifically include the following steps:

[0078] Step 301, during the process of the camera capturing images of the shooting scene, controlling the camera to focus on the captured faces;

[0079] This step is the same as step 201 in Embodiment 1, and will not be described in detail again.

[0080] Step 302. Based on the focusing data of the camera, calculate a first distance and a second distance between the camera and the collected face;

[0081] This step is the same as step 202 in Embodiment 1, and will not be described in detail again.

[0082] Step 303. Based on the first distance and the second distance, calculate the height line of the human body;

[0083] In the embodiment of the present invention, through the calculation method proposed in step 102 in the first embodiment, through Figure 1A The description and t...

Abstract

The embodiment of the invention provides a method for automatically adjusting a camera and a mobile terminal, and relates to the technical field of the camera. The method comprises the steps of controlling the camera to focus a collected face in a process of carrying out image collection on a photographing scene by the camera; calculating a photographing angle of the camera based on the focusing data of the camera; determining a target photographing angle; and controlling the camera to rotate until the photographing angle of the camera is adjusted to the target photographing angle. When a user carries out photographing, especially when the user carries out selfie, the optimum photographing angle can be obtained according to the current photographing scene; the camera is automatically adjusted to the optimum angle; and the operation efficiency and photographing quality of the user are improved. The problem that when the user a user carries out the photographing or selfie, and it is inconvenient to carry out the photographing by employing an external selfie device, the satisfactory photographing angle cannot be obtained due to the limitation of the length of human arms and the limitation of the rotation angles of wrists is 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 cameras enables users to get high-quality shooting experience. [0003] In many cases, when a user uses a mobile terminal to take pictures, especially when taking a selfie, the optional angles in the process of taking a selfie with the mobile terminal held ...
