Problems solved by technology

However, at present, the blur effect of pictures taken through the terminal is not ideal, the background blur effect is unnatural, the transition blur between the foreground and the background is obvious, and part of the foreground is often mistakenly regarded as the background part for blurring, resulting in poor blur effect

Embodiment 1

[0028] The image blurring method provided in this embodiment is applicable to the situation where a background blurred image is obtained by taking images with dual cameras, and the method can be performed by an image blurring device, which can be implemented by software and / or hardware, The device can be integrated in a terminal, such as a mobile phone, a tablet and other devices with a camera function. see Figure 1a , the method of this implementation specifically includes the following steps:

[0029] S110. Acquire a first image captured by the first camera of the dual cameras, and a second image captured by the second camera of the dual cameras.

[0030] Wherein, the first image and the second image are frame synchronous images.

[0031] Specifically, the terminal is equipped with dual cameras, which may be front dual cameras or rear dual cameras, and may be arranged according to preset rules, for example, the dual cameras may be arranged horizontally or vertically. The ...

Embodiment 2

[0046] This embodiment is optimized on the basis of the above embodiments, details not described in detail in this embodiment can be found in the above embodiments. see Figure 2a , the image blurring method provided in this embodiment includes:

[0047] S210. Acquire a first image captured by the first camera of the dual cameras, and a second image captured by the second camera of the dual cameras.

[0048] Wherein, the first image and the second image are frame synchronous images.

[0049] S220. Determine depth information of each feature point in the first image according to the first image and the second image.

[0050] S230. Perform layer processing on the first image according to the depth information, to obtain a layer processing result.

[0051] Specifically, the first image is layered according to the depth information, wherein the number of layered layers can be set as required. For example, the first image is divided into three layers named foreground layer, reco...

Embodiment 3

[0059] This embodiment provides an image blurring device, see image 3 , the device specifically includes:

[0060] The acquiring module 310 is configured to acquire a first image captured by the first camera lens of the dual cameras, and a second image captured by the second camera of the dual cameras, wherein the first image and the second image are frame synchronous images.

[0061] The determination module 320 is configured to determine the depth information of each feature point in the first image according to the first image and the second image.

[0062] The blurring module 330 is configured to perform blurring processing on the first image according to the depth information of each feature point in the first image.

[0063] Optionally, the determination module 320 includes:

[0064] A matching unit, configured to detect feature points corresponding to the first image and the second image, and match the feature points of the first image and the second image;

[0065]...

Abstract

The embodiment of the invention discloses an image blurring method and device, a terminal and a storage medium. The method comprises: acquiring a first image collected by a first camera lens in doublecameras and a second image collected by a second camera in the double cameras, wherein the first image and the second image are frame synchronous images; Determining depth information of each featurepoint in the first image according to the first image and the second image; And performing blurring processing on the first image according to the depth information of each feature point in the firstimage. Depth information of the first image is determined through the first image and the second image, blurring processing is carried out on the first image according to the depth information, foreground and background information of the image can be fully obtained, and therefore blurring of different degrees is carried out, and the image blurring effect is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to an image blurring method, device, terminal, and storage medium. Background technique [0002] In photography practice, background blur can set off the subject very well, and it is a shooting technique commonly used by photographers. Photographers generally use the large aperture of the SLR camera to achieve the effect of blurring the background of the shot picture, but professional SLR cameras with large aperture are expensive, and the use of telephoto lenses has many restrictions and is not easy to operate. [0003] With the development of technology, the pictures taken by the camera of the terminal can achieve the effect of blurring the background, which provides convenience for photographers. Due to the small size and easy portability of the terminal, low shooting technology and easy operation, it is widely used by users. However, at prese...
