Embodiment 1

[0054] figure 1 A flow chart of a photographing method provided in the first embodiment of the present invention is shown. In the embodiment of the present invention, two cameras are set on the same surface of the terminal: a first camera and a second camera. The same scene is captured by the first camera and the second camera at the same time, and two photos with different exposure levels are obtained, and then the final photo is synthesized based on the two obtained two photos with different exposure levels. The details are as follows:

[0055]Step S11 , metering the scene to be photographed through the first camera.

[0056] Before the photometry of the first camera, the parameters of the first camera and the second camera can be adjusted to ensure that the field angles of the first camera and the second camera are the same, so that the first camera and the second camera can capture the same scene, which is beneficial to the subsequent photo composition.

[0057] Wherein,...

Embodiment 2

[0082] figure 2 It shows a structural diagram of a photographing device provided by the second embodiment of the present invention, the photographing device can be applied to a terminal, and the terminal can include a user equipment that communicates with one or more core networks via a radio access network RAN , the user equipment may be a mobile phone (or called a "cellular" phone), a computer with a mobile device, etc., for example, the user equipment may also be a portable, pocket, handheld, computer built-in or vehicle-mounted mobile device, which Exchange voice and / or data with the radio access network. For another example, the terminal may include a smart phone, a tablet computer, a personal digital assistant PDA, a sales terminal POS, or a vehicle-mounted computer.

[0083] The photographing device includes: a scene metering unit 21 , an overexposure exposure time determination unit 22 , a camera exposure time determination unit 23 , a photographing unit 24 , and a p...

Abstract

The invention is suitable for the field of the mobile communications and provides a photographing method, a photographing device and a terminal. The method comprises the following steps: testing light of a scene needing to be shot by use of a first camera; determining the exposure time of the overexposure of the brightest region according to the light testing result; determining the exposure time of the first camera and the exposure time of a second camera according to the determined the exposure time of the overexposure of the brightest region, wherein the exposure time of the first camera is unequal to the exposure time of the second camera; photographing the scene needing to be shot simultaneously by use of the first camera and the second camera according to the determined exposure time of the first camera and the determined exposure time of the second camera; synthesizing a picture obtained by photographing the scene needing to be shot by use of the first camera and a picture obtained by photographing the scene needing to be shot by use of the second camera. The photographing method is capable of outputting a high-dynamic picture.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a photographing method, photographing device and terminal. Background technique [0002] At present, more and more functions are integrated in the terminal (smart phone or tablet computer). For example, in addition to the Internet access function, the camera function can also be realized by setting a camera on the terminal. [0003] However, when shooting scenes with large brightness differences through the existing cameras installed on the terminal, it is easy to overexpose in high-brightness areas and easy to underexpose in low-brightness areas. Because the dynamic range of the captured photos is too small, As a result, the photos taken are not good. Contents of the invention [0004] Embodiments of the present invention provide a photographing method, a photographing device, and a terminal, aiming at solving the problem that it is difficult to obtain photogra...
