Embodiment 1

[0024] see figure 1 , the autofocus method provided by Embodiment 1 of the present invention includes the following steps:

[0025] Step S101, during the process of continuously focusing on the photographed object, storing multiple frames of pictures collected by the camera;

[0026] In Embodiment 1 of the present invention, step S101 specifically includes the following steps:

[0027] Receive continuous focusing instructions;

[0028] Continuously focus on the object being photographed;

[0029] Obtain multiple frames captured by the camera;

[0030] storing the multi-frame pictures;

[0031] In Embodiment 1 of the present invention, the mobile terminal is in the preview state before taking pictures, that is, the picture of the viewfinder can be seen on the screen of the mobile terminal. It shows that the multi-frame images captured by the camera are stored in the mobile terminal memory at the same time. For example, if the frame rate is 15 frames and it takes 2 seconds ...

Embodiment 2

[0046] see figure 2 The auto-focus system provided by Embodiment 2 of the present invention includes: a storage module 11 , a first instruction receiving module 12 , a first acquisition module 13 , a judging module 14 , a first focusing module 15 and a second focusing module 16 .

[0047] The storage module 11 is used to store multiple frames of pictures collected by the camera during the process of continuously focusing on the photographed object;

[0048] In Embodiment 2 of the present invention, the storage module 11 specifically includes:

[0049] The second instruction receiving module is used to receive the instruction of continuous focusing;

[0050] A continuous focusing module, used for continuous focusing on the object to be photographed;

[0051] The second acquisition module is used to acquire multi-frame pictures collected by the camera;

[0052] a first storage module, configured to store the multi-frame pictures;

[0053] In Embodiment 2 of the present inve...

Abstract

The invention is suitable for the field of communication, and provides a method, a system and a mobile terminal of automatic focusing. The method comprises storing multiple frames of images collected by a camera in a continuous focusing process to shot objects, receiving the instruction of touch screen focusing, obtaining a frame of image collected by the camera at the moment, and judging whether the distinguishing degree between the frame of image collected by the camera at that moment and the multiple frames of images reaches a preset threshold value. If the distinguishing degree does not reach the preset threshold value, the multiple frames of images are directly used to carry out general focusing, and then meticulous focusing is carried out through a focusing motor. The method, the system and the mobile terminal of automatic focusing reduce focusing time, reduce image flutter, and improve user experience.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an automatic focusing method, system and mobile terminal. Background technique [0002] Most of the mobile terminals in the prior art have functions of continuous focus and touch screen focus. Continuous focusing refers to automatically focusing on the central area if it detects that the scene has not moved for a period of time. Touch screen focus refers to focusing on the area touched on the screen when a touch action is detected on the screen. [0003] Because it is not very urgent when people generally take pictures, continuous focusing has been completed when touching the screen to focus, but the existing touch-screen focusing technology does not use the information obtained by continuous focusing, and will re-execute the focusing process, so the focus If the time is long, the screen will shake and the user experience will be poor. Contents of the invention [0004]...
