Problems solved by technology

With the continuous popularization of smart phones, the majority of users use mobile phones to take pictures, and due to the limited thickness of mobile phones, mobile phones can only be equipped with small aperture lenses, so mobile phones can only generate weak blur effects when they are very close. Unable to generate blurred images in other scenarios

Embodiment 1

[0046] figure 1 It is a flow chart showing an image blurring processing method according to Embodiment 1 of the present invention.

[0047] refer to figure 1 , in step S110, acquire the main image and the auxiliary image obtained by shooting the same object with the dual cameras.

[0048] The dual camera can shoot the same scene at different angles to get two pictures, respectively the main picture and the auxiliary picture (or the left picture and the right picture), which of the two pictures is the main picture and which one is the auxiliary picture, determined by the dual camera before leaving the factory determined in a predetermined manner. Among them, the dual camera can be set on a mobile smart terminal that cannot be integrated with a large aperture lens due to its thickness, for example, a dual camera on a smart phone.

[0049] In the main picture and auxiliary picture obtained by shooting the same object with dual cameras, the main picture is the picture finally p...

Embodiment 2

[0060] figure 2 It is a flow chart showing an image blur processing method according to Embodiment 2 of the present invention.

[0061] refer to figure 2 , in step S210, acquire a main image and an auxiliary image obtained by shooting the same object with dual cameras.

[0062] For example, image 3 and Figure 4 The main and auxiliary images obtained in this embodiment are shown. The main picture and the supplementary picture are two pictures obtained by shooting the same scene with dual cameras at different angles, for comparison image 3 and Figure 4 It can be seen that the positions of the ears of the doll near the edge of the picture in the main picture and the auxiliary picture are different (different from the mouse pad on the desktop).

[0063] In step S220, depth data and depth confidence data are obtained according to the main image and the auxiliary image. Wherein, the depth data indicates the depth value of each corresponding pixel in the main image and t...

Embodiment 3

[0091] Figure 7 It is a logic block diagram showing an image blur processing device according to Embodiment 3 of the present invention. Those skilled in the art can understand that the "module" or "unit" in the embodiments of the present invention may be software modules or units such as "program module" or "program unit", respectively, or hardware, firmware or software, A module or unit formed by any means of hardware or firmware is not limited in this embodiment of the present invention; it will not be described again.

[0092] refer to Figure 7 , the image blur processing apparatus of this embodiment includes a first acquisition module 310 , a second acquisition module 320 , a correction module 330 and a blur module 340 .

[0093] The first acquisition module 310 is configured to acquire the main image and the auxiliary image obtained by shooting the same object with the dual cameras. The second acquisition module 320 is used to acquire depth data and depth confidence ...

Abstract

Embodiments of the invention provide an image blurring processing method and apparatus, a storage medium and an electronic device. The image blurring processing method comprises the following steps: obtaining a main image and an auxiliary image obtained by double cameras by shooting the same object; obtaining depth data and depth confidence data according to the main image and the auxiliary image,wherein the depth data indicate depth values of corresponding pixel points in the main image and the auxiliary image, and the depth confidence data indicate the confidence of the depth values in thedepth data; correcting at least one depth value in the depth data according to the depth confidence data; and performing blurring processing on the main image according to the corrected depth data. Byadoption of the technical scheme of the invention, the accuracy of the obtained depth data can be effectively improved, thus improving the blurring effect of the main image.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular, to an image blurring processing method, storage medium, device, and electronic equipment. Background technique [0002] The background blur of the image can make the subject clearly displayed, which is very popular among photography enthusiasts. At present, the image blurring effect is mainly realized by using the principle of optical imaging and using a large lens aperture on the hardware. Therefore, the image blurring function is mainly integrated in professional cameras such as SLR cameras. With the continuous popularization of smart phones, the majority of users use mobile phones to take pictures, and due to the limited thickness of mobile phones, mobile phones can only be equipped with small aperture lenses, so mobile phones can only generate weak blur effects when they are very close. Images with blur effects cannot be generated in other scenarios. ...
