first embodiment

As shown in FIG. 1 , it is a schematic flowchart of a photographing method according to a first embodiment of the present invention. The implementation process of the photographing method will be described in detail below in conjunction with this figure.

The first embodiment of the present invention provides a method for taking pictures, which is applied to a mobile terminal. The mobile terminal has a first camera and a second camera. The method for taking pictures includes:

Step 11, when the mobile terminal uses the first camera to take pictures, determine the first distance between the in-focus object of the first camera and the mobile terminal according to the focusing result of the successful focusing of the first camera;

It should be noted that the angle of view of the first camera is greater than that of the second camera, that is, the first camera is a wide-angle camera, and the second camera is a telephoto camera; usually, when the camera of a mobile terminal is turned on, the wide-angle camera is used by default The camera shoots images, because the wide-angle camera can only realize clear pictures of objects within a certain distance. When the wide-angle camera is working, the distance between the in-focus object in the current picture and the mobile terminal should be obtained in real time to judge the current Whether it is suitable to use a wide-angle camera to take pictures under the circumstances.

Step 12, if the first distance is greater than or equal to the first preset value, switch the camera for taking pictures from the first camera to the second camera.

It should be noted that when the acquired distance between the in-focus object and the mobile terminal has exceeded the working range of the wide-angle camera, it is necessary to switch to the telephoto camera for image taking.

In the embodiment of the present invention, by using the distance between the current in-focus object and the mobile terminal to adjust the camera for taking pictures, the automatic switching of the camera for taking pictures in the mobile terminal is realized, and the user's operations are reduced.

second embodiment

As shown in FIG. 2 , it is a schematic flowchart of a photographing method according to a second embodiment of the present invention. The implementation process of the photographing method will be described in detail below in conjunction with this figure.

The second embodiment of the present invention provides a method for taking pictures, which is applied to a mobile terminal. The mobile terminal has a first camera and a second camera. The method for taking pictures includes:

Step 21, when the mobile terminal uses the first camera to take pictures, determine a first distance between the in-focus object of the first camera and the mobile terminal according to the focusing result of the first camera focusing successfully;

It should be noted that the angle of view of the first camera is greater than that of the second camera, that is, the first camera is a wide-angle camera, and the second camera is a telephoto camera; usually, when the camera of a mobile terminal is turned on, the wide-angle camera is used by default The camera shoots images, because the wide-angle camera can only realize clear pictures of objects within a certain distance. When the wide-angle camera is working, the distance between the in-focus object in the current picture and the mobile terminal should be obtained in real time to judge the current Whether it is suitable to use a wide-angle camera to take pictures under the circumstances.

Step 22, if the first distance is greater than or equal to a first preset value, switch the camera for taking pictures from the first camera to the second camera.

It should be noted that when the distance between the in-focus object and the mobile terminal is beyond the working range of the wide-angle camera, it is necessary to switch to the telephoto camera to take pictures of images. After switching, the mobile terminal can use the telephoto The camera captures images.

Step 23: Determine a second distance between the in-focus object of the preset camera and the mobile terminal according to the focus result of the preset camera focusing successfully;

It should be noted that after switching the camera currently taking pictures to the telephoto camera, it is also necessary to obtain the distance between the in-focus object in the current picture and the mobile terminal in real time, so as to judge whether it is suitable to continue using the telephoto camera in the current situation. The camera used to take pictures and acquire the distance may be a wide-angle camera or a telephoto camera currently taking pictures.

Step 24, if the second distance is less than or equal to the second preset value, switch the camera for taking pictures from the second camera to the first camera;

It should be noted that when the wide-angle camera is used to acquire the distance of the in-focus object, when the acquired distance from the in-focus object to the mobile terminal is less than or equal to the second preset value, it indicates that the distance from the in-focus object to the mobile terminal falls within Within the scope of use of the wide-angle camera, the camera for taking pictures should be switched from the telephoto camera to the wide-angle camera at this time; It is equal to the second preset value, indicating that the distance between the in-focus object and the mobile terminal no longer satisfies the conditions for using the telephoto camera. At this time, the camera for taking pictures should be switched from the telephoto camera to the wide-angle camera.

It should also be noted that, in order to avoid frequent camera switching, when the wide-angle camera is used to acquire the distance of the in-focus object, the first preset value should be greater than the second preset value.

Specifically, the implementation process of step 21 includes:

Step 211, moving the motor of the first camera to obtain the focus position of the motor of the first camera when the focus is successful;

Step 212: Acquire a first distance between the in-focus object and the mobile terminal according to the in-focus position.

It should be noted that the specific implementation of step 212 is: obtain the current value of the drive integrated circuit when it is in the focus position; and then according to the corresponding relationship between the current value and the distance between the in-focus object and the mobile terminal (The correspondence between the current value and the distance between the in-focus object and the mobile terminal is set in advance and stored inside the mobile terminal), and the first distance between the in-focus object and the mobile terminal is obtained.

It should be noted that the camera principle of the mobile terminal with automatic camera function is to change the focus position of the lens through the movement of the VCM (Voice Coil Motor) to realize the clarity of objects at different distances, and the movement of the VCM is through the Driver IC (driver integrated Circuit) controls the magnitude of the current to change the position of the lens, and the position of the lens is linearly related to the magnitude of the current. By judging the magnitude of the current at the position of the clear point of the picture, the distance of the object to be photographed can be judged, so as to realize the automatic switching of the camera. The size of the code value is used to determine the position of the object.

It should be noted that the specific implementation process of step 23 is similar to that of step 21, and will not be repeated here.

In the actual application process, the photographing method applied in this embodiment will be described in detail as follows.

As shown in Figure 3, the specific process for the mobile terminal to take pictures with dual cameras is as follows:

Step 31, the mobile terminal enters the wide-angle camera photography mode;

When the user turns on the camera function of the mobile terminal, the mobile terminal defaults to a wide-angle camera camera mode.

Step 32, using the wide-angle camera to obtain the first distance between the in-focus object and the mobile terminal;

This step is mainly to move the motor of the autofocus module of the wide-angle camera, analyze the focus value to judge whether it is in the clearest position, until the focus value is in the clearest position (that is, the focus is successful), and then obtain the first distance from the in-focus object to the mobile terminal a distance.

Step 33, judging whether the first distance is greater than or equal to the first threshold, if the first distance is less than the first threshold, then execute step 34, otherwise execute step 35;

Step 34, the mobile terminal remains in the state of taking pictures with the wide-angle camera;

Step 35, the mobile terminal switches the camera for taking pictures from a wide-angle camera to a telephoto camera;

Step 36, the wide-angle camera continues to work in the background to obtain the second distance between the in-focus object and the mobile terminal;

It should be noted that step 36 is implemented in the same manner as step 32 .

Step 37, judging whether the second distance is less than or equal to the second threshold, if the second distance is less than the second threshold, jump to step 31, otherwise execute step 38;

Step 38, the mobile terminal remains in the state of taking pictures with the telephoto camera;

Step 39, use the current camera to take pictures of images.

In the embodiment of the present invention, there is no need to add any hardware facilities in the mobile terminal, and by using the distance between the current focus object and the mobile terminal to adjust the camera for taking pictures, the automatic switching of the camera for taking pictures in the mobile terminal is realized, thereby realizing large, Fast switching of small shooting scenes reduces user operations.
