Problems solved by technology

Although this method can achieve a certain background blur effect, because the foreground detection technology cannot separate the subject from the background well, and at the same time directly blur the background image, the subject cannot be well blended into the image. into the background image, resulting in less realism in the bokehed image

Embodiment 1

[0066] Such as figure 2 As shown in the figure, this figure shows a shooting method for blurring the background provided by the embodiment of the present invention. It can be seen from the figure that the method may include:

[0067] S210. Control the first camera and the second camera to shoot the subject at the same time, and respectively generate a first target image and a second target image; wherein, the clarity of the first target image is higher than that of the second target image Spend;

[0068] Here, it should be noted that the first camera and the second camera are arranged on the same horizontal line on the same side of the terminal, and the distance between the first camera and the second camera is smaller than a preset distance threshold. The first camera is used to acquire a first target image with higher image definition, and the second camera is used to acquire a second target image with lower image definition, that is, a target image that meets the backgrou...

Embodiment 2

[0092] In order to facilitate the understanding of the above technical solutions, such as Figure 7 As shown, the figure shows a preferred implementation process of a background blur shooting method, which is applied to a mobile terminal with a front dual camera or a rear dual camera. It can be seen from the figure that the implementation process may specifically include Follow the steps below:

[0093] S710. The terminal controls the first camera and the second camera to simultaneously shoot the subject to generate a first target image and a second target image respectively; wherein, the definition of the first target image is higher than that of the second target image clarity;

[0094] S720. The terminal displays the first target image and prompt information on the touch screen; wherein the prompt information is used to prompt the user to select a cutout range in the first target image;

[0095] S730. The terminal detects touch operation information received on the touch ...

Embodiment 3

[0104] Based on the same technical idea as mentioned above, such as Figure 9 As shown, this figure shows a shooting terminal 90 with blurred background provided by an embodiment of the present invention, which is characterized in that the terminal includes: a shooting module 910, an extraction module 920 and an image fusion module 930; wherein,

[0105] The photographing module 910 is configured to control the first camera and the second camera to photograph the subject at the same time, and respectively generate a first target image and a second target image; wherein, the definition of the first target image is higher than that of the The sharpness of the second target image;

[0106] The extraction module 920 is configured to extract the subject included in the first target image;

[0107] The image fusion module 930 is configured to fuse the subject extracted from the first target image with the second target image to generate a third target image.

[0108]In the above s...

Abstract

The embodiment of the invention discloses a bokeh photographing method and a terminal. The method comprises the following steps: controlling a first camera and a second camera to simultaneously photograph a photographing main body, so as to generate a first target image and a second target image respectively, wherein the definition of the first target image is higher than that of the second target image; extracting the photographing main body in the first target image; fusing the photographing main body extracted from the first target image with the second target image, so as to generate a third target image. The terminal can realize the image effect of bokeh and a clear photographing main body through the method, and the whole body of the fused image is relatively real and natural.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a background blurring shooting method and a terminal. Background technique [0002] When shooting blurred background photos in SLR cameras, the telephoto lens of the SLR camera is used to directly change the optical imaging, so that only within a certain object distance range, the imaging is clear. Outside this range, the imaging will be different to varying degrees. Blurring, this effect highlights the key things in the photo and ignores other supporting things. It is often used in photography such as portraits and artworks. [0003] This technique uses the aperture, focus distance (object distance) and focal length variability in the lens to directly adjust the blur effect. The larger the aperture, the closer the focus distance or the greater the focal length, the stronger the background blur effect. . Therefore, for a camera that can directly capture the bac...
