Embodiment 1

[0024] This embodiment is applied to the automatic focus of the front camera of the electronic device. Specifically, such as figure 1 As shown, it is a flow chart of the main steps of the method for auto-focusing in the embodiment of the present invention, and the method includes:

[0025] Step 101, determine the source of the camera order.

[0026] In this step, specifically, after the electronic device is started, the image is output to the screen of the electronic device, and at this time, the electronic device waits for a camera command. When the electronic device obtains the photographing command, determine the source of the photographing command.

[0027] Step 102, determine the depth-of-field mode according to the source of the photographing command.

[0028] Specifically, after the focus is completed, a clear image can be formed in the range before and after the focus, and this distance range before and after is called the depth of field, also known as the depth of ...

Embodiment 2

[0036] Such as figure 2 As shown, it is a detailed flow chart of the steps of the autofocus method in the embodiment of the present invention, and the method includes:

[0037] Step 201, determine the source of the camera order.

[0038] In this step, the source of the electronic device may be manually input, or wired or wirelessly transmitted. Specifically, the manner of manual input may be to manually input a photographing command on a virtual photographing button on the screen of the electronic device or a physical photographing button on the electronic device. The way of wired transmission can be to input camera commands through audio interface and other methods for long-distance photography, such as wired selfie sticks, etc.; the wireless transmission method can be to input camera commands through Bluetooth and other methods for long-distance photography, such as Bluetooth Selfie stick, wireless voice trigger camera command, etc.

[0039] Step 202, if the source of the...

Embodiment 3

[0055] Such as Figure 4 As shown, it is a structural block diagram of an electronic device, which includes a front camera, and also includes:

[0056] The first determining module 301 is configured to determine the source of the photographing order;

[0057] The second determination module 302 is configured to determine the depth of field mode according to the source of the photographing command;

[0058] A processing module 303, configured to search for focus in the focus area corresponding to the depth of field mode, and obtain a focus result when the focus is successful;

[0059] The control module 304 is configured to control the driving mechanism to drive the front camera to focus according to the focusing result.

[0060] In this embodiment, the electronic device determines the source mode of the photographing command through the first determination module, and then determines the depth of field mode through the second determination module according to the source mode...

Abstract

The present invention provides an automatic focusing method and an electronic device. The method is applied to the front camera of the electronic device. The method comprises the steps of determining the source mode of a photographing command; according to the source mode of the photographing command, determining a depth-of-field mode; searching and focusing within the focusing area corresponding to the depth-of-field mode; after the focusing is successfully done, obtaining a focusing result; according to the focusing result, controlling a driving mechanism to drive the front camera to focus. According to the invention, the stroke and the time for searching the driving mechanism are reduced, and the searching efficiency is improved. The user experience is also improved.

Description

technical field [0001] The invention relates to the field of electronics, in particular to an automatic focusing method and electronic equipment. Background technique [0002] With the advent of the mobile Internet era, mobile phone products are becoming more and more popular. In daily life, the mobile phone camera function is a function with a high usage rate by every user. In the process of taking pictures, users have higher and higher requirements for the quality of the photos taken and the playability of the camera. In addition, users have higher and higher requirements for the resolution of the camera. In response to this phenomenon, the effect and playability of the front camera of the mobile phone have become one of the major selling points and pain points for users. In the front camera, for example, the front camera is fixed-focus, which cannot make the best photo effect when taking pictures of still life at different distances. For example, when using various selfi...
