Embodiment 1

[0023] refer to figure 1 , shows a flow chart of steps of a method for adjusting the zoom factor of a camera according to Embodiment 1 of the present invention.

[0024] The method for adjusting the zoom factor of the camera in the embodiment of the present invention includes the following steps:

[0025] Step 101: Start the camera.

[0026] Before taking pictures through the mobile terminal, the user needs to start the camera. The camera activated in the embodiment of the present invention can be either a front-facing camera or a rear-facing camera.

[0027] Step 102: Receive a finger pressing operation on the fingerprint recognition area.

[0028] The finger may be any specific finger preset by the user. Users can pre-set specific fingers that can adjust the zoom factor of the camera. Wherein, there may be one or more specific fingers. When the user pre-adjusts the zoom factor of the camera with a specific finger, the user can use the specific finger to press the finge...

Embodiment 2

[0040] refer to figure 2 , shows a flow chart of steps of a method for adjusting the zoom factor of a camera according to Embodiment 2 of the present invention.

[0041] The method for adjusting the zoom factor of the camera in the embodiment of the present invention specifically includes the following steps:

[0042] Step 201: Preset the corresponding relationship between the range of the fingerprint pressing area of ​​the finger and the zoom factor.

[0043] The user can pre-set the corresponding relationship between the finger pressing area range and the zoom factor, and the mobile terminal presets the corresponding relationship between each fingerprint pressing area range and the zoom factor according to the user's setting operation.

[0044] The number of divisions of the fingerprint pressing area of ​​the finger can be set by those skilled in the art according to actual needs. It can be set to five fingerprint pressing area ranges, four fingerprint pressing area range...

Embodiment 3

[0066] refer to Figure 4 , shows a structural block diagram of a mobile terminal according to Embodiment 3 of the present invention.

[0067] The mobile terminal according to the embodiment of the present invention includes: a starting module 401, which is used to start the camera; an operation receiving module 402, which is used to receive the pressing operation of the finger on the fingerprint identification area; an area determination module 403, which is used to determine the fingerprint covered by the pressing operation Press area; multiplier determination module 404, used to determine the zoom multiplier corresponding to the fingerprint pressing area; adjustment module 405, used to adjust the preview image according to the zoom multiplier determined by the multiplier determination module 404.

[0068] In the mobile terminal provided by the embodiment of the present invention, after the camera is turned on, the pressing operation of the finger on the fingerprint identifi...

Abstract

The invention provides a method for adjusting zoom magnification of a camera and a mobile terminal. The method comprises the steps of starting the camera; receiving a press operation of a finger on a fingerprint recognition area; determining a fingerprint press area covered by the press operation; determining a zoom magnification corresponding to the fingerprint press area; and adjusting a preview image according to the zoom magnification. According to the scheme of adjusting the zoom magnification of the camera provided by the invention, a user can adjust the zoom magnification of the camera by controlling the press area of the finger on the fingerprint recognition area, and user operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to a method for adjusting the zoom factor of a camera and a mobile terminal. Background technique [0002] With the continuous improvement of mobile terminal camera pixels, the use of mobile terminals for image capture has basically replaced traditional cameras and video cameras. The mobile terminal can meet the user's needs for shooting on any occasion and at any time. [0003] When shooting through the camera set on the mobile terminal, the user often needs to adjust the zoom factor of the camera, so as to adjust the magnification factor of the subject in the preview image. At present, there are mainly two solutions for adjusting the zoom factor of the camera: [0004] The first method: slide two fingers simultaneously on the preview screen of the mobile terminal to reduce or increase the zoom factor of the camera. Specifically, if the distance between the two fingers is re...
