Embodiment 1

[0024] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of an image processing method according to an embodiment of the present invention, which is applied to a mobile terminal, and the mobile terminal includes at least two cameras, and may specifically include the following steps:

[0025] Step 101, using the first camera and the second camera to perform distance measurement on the target subject, and obtain distance values ​​between the mobile terminal and multiple feature points of the target subject;

[0026] In the embodiment of the present invention, the principle of triangulation is adopted, the first camera and the second camera are used to measure the distance of the target subject at the same time, and the distance value between the mobile terminal and the multiple feature points of the target subject is obtained, and the distance value can be The value of the distance from the mobile terminal to different points on the "surface" of the targe...

Embodiment 2

[0034] refer to image 3 , which shows a flow chart of the steps of Embodiment 2 of an image processing method according to an embodiment of the present invention, which is applied to a mobile terminal, and the mobile terminal includes at least two cameras, and may specifically include the following steps:

[0035] Step 201, acquiring focal length parameters of the first camera and the second camera;

[0036] In the embodiment of the present invention, the focal length parameters of the first camera and the second camera are acquired, and the focal length parameters may be parameters set by the user according to actual conditions. The focal length parameter refers to the distance from the lens center to the CCD (Charge-coupled Device) imaging plane in the camera of the mobile terminal, and the focal length information can be set according to the size of the focal length information of different mobile terminals. In the embodiment of the present invention , the first camera an...

Embodiment 3

[0059] Figure 4 is a block diagram of a mobile terminal according to an embodiment of the present invention. Figure 4 The mobile terminal 300 shown includes a distance value acquisition module 301 , a first image acquisition module 302 and an image information extraction module 303 .

[0060] The distance value acquisition module 301 is used to use the first camera and the second camera to simultaneously measure the distance of the target subject, and obtain the distance values ​​between the mobile terminal and a plurality of feature points of the target subject;

[0061] A first image obtaining module 302, configured to collect a first image including a target subject through the first camera;

[0062] The image information extraction module 303 is configured to extract the image information of the target subject from the first image according to the plurality of distance values.

[0063] Optionally, the terminal 300 further includes:

[0064] a second image obtaining mo...

Abstract

An embodiment of the invention provides an image processing method and a mobile terminal. The method is characterized by carrying out distance measurement on an object main body by adopting a first camera and a second camera to obtain distance values between the mobile terminal and a plurality of feature points of the object main body; collecting a first image comprising the object main body through the first camera; and according to the plurality of distance values, extracting image information of the object main body from the first image. By adopting the first camera and the second camera to carry out distance measurement on the object main body, hardware resources are utilized effectively, and functions of the hardware resources are enriched; by obtaining the first image through the first camera, power consumption is reduced and resources are saved; and by extracting the image information of the object main body according to the plurality of distance values, the image information of the object main body can be extracted accurately and effectively, image matting accuracy is greatly improved, and user experience is enhanced.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an image processing method and a mobile terminal. Background technique [0002] With the continuous development of electronic products, mobile terminals with shooting functions are becoming more and more popular. Users can use them to take pictures anytime and anywhere, and the resulting images are sent to relatives and friends in the form of multimedia text messages, etc., which is convenient and fast. . [0003] Mobile terminals such as smart phones are no longer simple communication tools, but handicrafts that integrate leisure, entertainment and communication functions. At the same time, users have higher and higher requirements for shooting effects, and users also have higher and higher requirements for the quality of captured images. Users usually need to change the background because the background is not coordinated. The accuracy of portrait recognition...
