Embodiment 1

[0028] refer to figure 1 As shown, the embodiment of the present invention provides a shooting method, which is applied to a mobile terminal, and the above mobile terminal includes a camera; the above method may specifically include steps 101-104:

[0029] Step 101: Obtain the preview image data collected by the aforementioned camera.

[0030] In the embodiment of the present invention, after the camera of the mobile terminal is started, the preview image data collected by the camera is acquired. When the aforementioned cameras are dual-cameras, preview image data with depth information collected by the aforementioned dual-cameras may be acquired.

[0031] The aforementioned mobile terminals include but are not limited to mobile terminals such as mobile phones, tablet computers, notebook computers, palmtop computers, navigation devices, wearable devices, smart bracelets, and pedometers.

[0032] Step 102: When at least one human face feature is detected in the preview image ...

Embodiment 2

[0057] refer to figure 2 As shown, the embodiment of the present invention provides a shooting method, which is applied to a mobile terminal, and the above mobile terminal includes a camera; the above method may specifically include steps 201-210:

[0058] Step 201: Obtain multiple portrait image samples.

[0059] The above-mentioned portrait image samples can be derived from a library in the cloud or in a memory, from image data captured by a camera or a camera of a mobile terminal, or from a third-party APP (Application, mobile terminal application program), etc.; this embodiment of the present invention does not make any limit.

[0060] Because different portrait image samples come from different sources, the color scheme may vary. Therefore, in the embodiment of the present invention, each portrait image sample can be converted into a unified color mode, such as RGB mode, CMYK mode, etc., so as to facilitate the extraction of color features through a unified color chann...

Embodiment 3

[0098] refer to image 3 As shown, the embodiment of the present invention provides a mobile terminal, including a camera; the above mobile terminal also includes:

[0099] A preview image acquisition module 301, configured to acquire the preview image data collected by the camera;

[0100] A portrait color feature acquisition module 302, configured to acquire at least one portrait color feature corresponding to the above-mentioned face feature when detecting that there is at least one face feature in the preview image data;

[0101] A blurred area determination module 303, configured to determine the portrait area and background area of ​​the preview image data according to the portrait color features;

[0102] The blur processing module 304 is configured to perform blur processing on the above-mentioned background area to obtain target image data when a photographing instruction is detected.

[0103] refer to Figure 4 shown in the above image 3 On the basis of, optiona...

Abstract

Embodiments of the invention relate to the field of communication, in particular to a shooting method and a mobile terminal. The method is applied to the mobile terminal. The mobile terminal comprisesa camera. The method comprises the following steps of obtaining preview image data collected by the camera; when at least one facial feature is detected in the preview image data, obtaining at leastone portrait color feature corresponding to the facial feature; determining a portrait region and a background region of the preview image data according to the portrait color feature; and when a shooting instruction is detected, carrying out fuzzy processing on the background region to obtain target image data. According to the embodiments of the invention, the mobile terminal can shoot directlyand conveniently to obtain a portrait picture with a background blurring effect in order to be convenient for a user to immediately share the portrait picture through social software, so that the useroperation is simplified; the data processing pressure to the mobile terminal is smaller, so that the user cannot feel the delay in a shooting process, and thus the operation experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, to a photographing method and a mobile terminal. Background technique [0002] When the user uses the camera of the mobile terminal to take pictures, it is always impossible to capture the background blur effect of the portrait picture similar to the optical large aperture of the SLR camera. Therefore, it is often necessary to post-process the portrait picture with the help of image processing software to achieve the portrait picture The effect of bokeh. [0003] That is to say, the mobile terminals currently on the market cannot intelligently and directly identify the portrait area when taking portrait photos, and perform background blur effects on parts other than the portrait area, so they cannot have the background blur effect after taking pictures. Instantly share your portrait pictures on social software. [0004] In short, when there is a user demand for...
