Embodiment 1

[0030] refer to figure 1 , which shows a flow chart of the steps of a photographing method in Embodiment 1 of the present invention, which may specifically include the following steps:

[0031] Step 101, when a shooting start instruction is received, an optimal dimming model is determined by analyzing the background area and the face area in the acquired real-time image frame.

[0032] The embodiments of the present invention are applicable to mobile terminals capable of taking pictures, videos, and dynamic pictures. Wherein, the mobile terminal includes but is not limited to a mobile phone and a tablet computer.

[0033] The embodiments of the present invention can analyze each image frame captured in real time, and perform light adjustment, so as to ensure that each frame of image can achieve the best shooting effect and layering. It can be understood that this embodiment of the present invention is also applicable to capturing a single image.

[0034] Specifically, for a...

Embodiment 2

[0047] refer to figure 2 , which shows a flow chart of the steps of a photographing method in Embodiment 2 of the present invention, which may specifically include the following steps:

[0048] Step 201, acquire an image frame in real time, and determine a face area and a background area in the image frame.

[0049] In the embodiment of the present invention, different dimming models may be used to perform brightness processing on each image frame.

[0050] Specifically, firstly, a face area is determined; then, other areas than the face area are used as background areas. Wherein, the face area can be obtained through face recognition and / or user designation.

[0051] In the actual shooting process, the user can specify the target area by clicking or other operations, so that the mobile terminal can perform special processing according to the target area specified by the user. In the embodiment of the present invention, the mobile terminal may perform lighting processing acc...

Embodiment 3

[0077] refer to image 3 , shows a structural block diagram of a photographing device according to Embodiment 3 of the present invention.

[0078] The shooting device 300 includes: a dimming model determination module 301 , a brightness adjustment module 302 , and a captured image saving module 303 .

[0079] The functions of each module and the interaction between each module are introduced in detail below.

[0080] The dimming model determination module 301 is used to determine the optimal dimming model by analyzing the background area and the face area in the acquired real-time image frame when the shooting start instruction is received;

[0081] A brightness adjustment module 302, configured to adjust the brightness and color temperature of the face area in the real-time image frame by using the optimal dimming model;

[0082] The captured image saving module 303 is configured to save the image set with the adjusted face area to obtain the captured image set when receivi...

Abstract

The invention provides a photographing method, a photographing device and a mobile terminal, wherein the method comprises the following steps: when a photographing starting order is received, analyzing a background region and a human face region in an acquired real-time image frame to determine an optimal dimming model; adjusting brightness and color temperature of the human face region in the real-time image frame through the optimal dimming model; and when a photographing ending order is received, storing an adjusted image set of the human face region to obtain a photographed image set. A problem of relatively week sense of depth of pictures and relative poor photographing effects is solved, and a beneficial effect of enhancing the sense of depth of pictures and the photographing effectsis achieved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a photographing method, device and mobile terminal. Background technique [0002] With the popularization of mobile terminals, users can not only take still pictures through mobile terminals, but also can take videos, make dynamic pictures and other picture collections composed of multiple frames of continuous pictures. [0003] In practical applications, when using a mobile terminal to shoot multiple frames of continuous pictures, when receiving an instruction from the user to start shooting, the pictures are collected directly through the camera until the end command is received from the user, and the obtained multi-frame pictures are used as Shooting results. It can be seen that the multi-frame continuous pictures taken have not undergone any lighting processing, the picture layering is weak, and the shooting effect is poor, thereby reducing the user's photo ...
