Embodiment 1

[0028] figure 1 It is a flow chart of the photographing method of an embodiment of the present invention. figure 1 The shown shooting method is applied to a mobile terminal with a camera, and the method includes:

[0029] Step 101. Obtain the first photographing parameters of the preview image.

[0030] The method described in the embodiment of the present invention is applied to a mobile terminal with a camera, and the mobile terminal can be in various forms, such as a mobile phone, a tablet, a notebook, a camera, and the like.

[0031] The preview image is an image presented on the display screen of the mobile terminal.

[0032] The first photographing parameter is a parameter that the mobile terminal needs to use when taking a photograph, such as one or more of parameters such as sensitivity, exposure time, exposure value, whether to enable a flash function, and the like. The first photographing parameters can come from various sources, such as default photographing para...

Embodiment 2

[0049] figure 2 It is a flow chart of the photographing method of an embodiment of the present invention. figure 2 The shown shooting method is applied to a mobile terminal with a camera, and the method includes:

[0050] Step 201. Obtain a first photographing parameter of a preview image.

[0051] In the embodiment of the present invention, the first photographing parameter includes an exposure value. The source of the first photographing parameter can be various, for example, the first photographing parameter is a default parameter and can be read from a preset storage location. The default first photographing parameter can be unique; different first photographing parameters can also be set in advance for different shooting environments, and after the mobile terminal obtains the preview image, it determines the corresponding first photographing parameter according to the information type of the preview image.

[0052] Step 202, receiving an operation from the user to mo...

Embodiment 3

[0069] image 3 is a block diagram of a mobile terminal according to an embodiment of the present invention. image 3 The illustrated mobile terminal includes a camera, and the mobile terminal includes:

[0070] The first photographing parameter acquiring module 301 is configured to acquire the first photographing parameter of the preview image.

[0071] A selection operation receiving module 302, configured to receive a user's selection operation on the target object in the preview image;

[0072] The second photographing parameter receiving module 303 is configured to receive the second photographing parameter for the target object input by the user.

[0073] The image acquisition module 304 is configured to, when a photographing instruction is detected, obtain a first image by photographing with the first photographing parameters, and obtain a second image by photographing with the second photographing parameters.

[0074] A target image obtaining module 305, configured ...

Abstract

The embodiment of the invention discloses a photographing method and a mobile terminal. The method is applied to a mobile terminal with a camera, and the method includes: acquiring a first photographing parameter of a preview image, receiving a user's selection operation on a target object in the preview image, and receiving the first parameter of the target object input by the user. Two photographing parameters, when a photographing instruction is detected, the first photographing parameter is used to obtain a first image, and the second photographing parameter is photographed to obtain a second image, and the target object in the second image is synthesized to the position of the target object in the first image to obtain a target image. The method described in the embodiment of the present invention realizes the adjustment of the image parameters of the target object in the target image. When the photographing parameter is the exposure value, the image brightness of the target object in the obtained target image is improved, and the images of other objects meet the brightness requirements. At the same time, there will be no overexposure of the image, and the image quality is better.

Description

technical field [0001] The invention relates to the communication field, in particular to a photographing method and a mobile terminal. Background technique [0002] With the continuous development of terminal functions, the camera function has become one of the basic functions of the terminal. During the photo taking process, for a photographer with a darker skin color, the face recognition function of the terminal may not be able to quickly recognize the photographer's face, which will affect the normal progress of the photo; when there are multiple photographers with different skin colors, The resulting photo has a darker, less aesthetically pleasing image for a photographer with a darker skin tone. [0003] In the prior art, it is possible to increase the brightness of the subject in the photographed image by turning on the fill light or increasing the exposure, but the method of using the fill light to increase the exposure often leads to overexposed areas in the obtai...
