Embodiment 1

[0031] refer to figure 1 , which shows a flow chart of Embodiment 1 of a camera anti-shake method according to the present invention, which may specifically include:

[0032] Step 101. Obtain the ambient brightness information of the photographing scene and the initial exposure time of the camera.

[0033] The embodiment of the present invention is applicable to a mobile terminal with a camera. Even if there is shaking during the shooting process, a higher-quality image can be taken, and there is no need to be equipped with an OIS optical image stabilization lens, which can not only save hardware costs, but also save OIS The space volume occupied by the optical anti-shake lens can improve the aesthetics of the mobile terminal. The mobile terminal may be any mobile terminal with a camera, for example, the mobile terminal may include a smart phone, a tablet computer, a notebook computer, etc. The embodiment of the present invention does not limit the specific form of the mobile...

Embodiment 2

[0048] In this embodiment, on the basis of the first embodiment above, multiple frames of reference images with the same sensitivity value and exposure time can be captured according to the adjusted sensitivity value and initial exposure time. refer to figure 2 , which shows a flow chart of Embodiment 2 of a camera anti-shake method according to the present invention, which may specifically include:

[0049] Step 201. Acquire ambient brightness information of the photographing scene and the initial exposure time of the camera.

[0050] In a specific application, when the mobile terminal receives a photographing instruction, it can read the sensitivity value isoValue or the current brightness value current-luma of the camera, and the initial exposure time expoTime.

[0051] Step 202: Shoot a frame of original image according to the ambient brightness information and the initial exposure time.

[0052] After obtaining the camera's sensitivity value isoValue or current brightn...

Embodiment 3

[0085] In this embodiment, on the basis of the first embodiment above, multiple frames of reference images with different sensitivity values ​​and exposure times can be captured according to the adjusted sensitivity value and initial exposure time. refer to image 3 , which shows a flow chart of Embodiment 3 of a camera anti-shake method according to the present invention, which may specifically include:

[0086] Step 301. Acquire the ambient brightness information of the photographing scene and the initial exposure time of the camera.

[0087] In a specific application, when the mobile terminal receives a photographing instruction, it can read the sensitivity value isoValue or the current brightness value current-luma of the camera, and the initial exposure time expoTime.

[0088] Step 302: Shoot a frame of original image according to the ambient brightness information and the initial exposure time.

[0089] After obtaining the camera's sensitivity value isoValue or current...

Abstract

The embodiments of the invention provide a shooting anti-shaking method and a mobile terminal, wherein the method is applied to the mobile terminal with a camera and comprises the steps of: obtaining ambient brightness information of a shot scene and an initial exposure time of the camera; according to the ambient brightness information and the initial exposure time, shooting a frame of original image; reducing the initial exposure time, adjusting the sensitivity value of the camera, and then shooting a plurality of frames of reference images; according to the plurality of frames of reference images, determining one frame of target image; and carrying out combination processing on the target image and the initial image, and generating a final image. By adopting the shooting anti-shaking method, the image having the anti-shaking effect and good in quality is obtained without adding hardware cost.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular to a method for taking pictures and anti-shake and a mobile terminal. Background technique [0002] With the continuous development of electronic information technology, mobile terminals such as smartphones and tablet computers are widely used, and mobile terminals have become an indispensable necessity in users' lives. At present, the photographing function has become one of the indispensable functions in the mobile terminal, and how to improve the quality of photographed photographs has also become a hot research topic. [0003] In practical applications, if shaking occurs during shooting, such as when the photographer's hand shakes, or when shooting a moving object, it is easy to cause blurred or smearing of the captured image. [0004] In order to solve the above problems, an existing solution can equip a mobile terminal with an OIS optical image stabil...
