Embodiment 1

[0021] refer to figure 1 , which shows a flow chart of an embodiment of a photographing method of the present invention, which may specifically include the following steps:

[0022] Step 101. Acquire image data during continuous image acquisition by the camera.

[0023] In order to reduce the user's waiting time and improve processing efficiency, at least two frames of image data can be continuously captured during the period from the start of the camera application to the user triggering the shooting. Take 5 frames of image data, because the light is relatively weak, the captured single-frame image data will generally be blurred, that is, the single-frame image data contains fewer pixels and the resolution is lower. Since the mobile terminal will inevitably shake during the shooting process, the image data of each frame continuously captured will not be exactly the same, that is, the pixel distribution of each frame of image data will not be exactly the same. The mobile ter...

Embodiment 2

[0035] refer to figure 2 , showing a flow chart of another embodiment of the photographing method of the present invention, which may specifically include the following steps:

[0036] Step 201. Acquire image data during continuous image acquisition by the camera.

[0037] In order to reduce the user's waiting time and improve processing efficiency, at least two frames of image data can be continuously captured during the period from the start of the camera application to the user triggering the shooting. Take 5 frames of image data, because the light is relatively weak, the captured single-frame image data will generally be blurred, that is, the single-frame image data contains fewer pixels and the resolution is lower. Since the mobile terminal will inevitably shake during the shooting process, the image data of each frame continuously captured will not be exactly the same, that is, the pixel distribution of each frame of image data will not be exactly the same.

Embodiment 3

[0074] refer to Figure 5 , which shows a structural block diagram of a mobile terminal embodiment of the present invention, which may specifically include the following modules:

[0075] The image acquisition module 501 is configured to acquire image data during continuous image acquisition by the camera.

[0076] The scene identification module 502 is configured to identify whether the image data acquired by the image acquisition module is a preset shooting scene.

[0077] The image synthesis module 503 is configured to continuously perform image synthesis on each frame of images collected in the background to generate at least two frames of synthesized images when the preset shooting scene is recognized.

[0078] The image cache module 504 is configured to sequentially cache at least two frames of synthesized images generated by the image synthesis module.

[0079] The image generation module 505 is configured to generate a photo based on at least two frames of synthesize...

Abstract

Embodiments of the invention provide a photographing method and a mobile terminal. The photographing method comprises the following steps of obtaining image data in a continuous image collection process of a camera; identifying whether the image data is a preset shooting scene; when identifying that the image data is the preset shooting scene, continuously carrying out image synthesis on each frame of collected image at the background and generating at least two frames of synthetic images; caching at least two frames of synthetic images in sequence; and when receiving a photographing instruction, generating a picture based on the at least two frames of synthetic images. Through synthesizing the data of the at least two frames of synthetic images before receiving the photographing instruction, the picture can be obtained immediately after a user triggers shooting, so that the shooting efficiency is improved.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a photographing method and a mobile terminal. Background technique [0002] When a mobile terminal shoots a night scene, due to insufficient light, the captured single-frame image is generally blurred. The image quality is relatively poor and cannot meet the requirements of users. [0003] In order to improve the image quality, when shooting night scenes, at least two frames of images are captured and synthesized to obtain a final image. Generally, in order to save storage space, only a small amount of images are cached before clicking the shooting button. When the shooting button is clicked, several frames of images need to be continuously cached. After the user clicks the shooting button, the mobile terminal may prompt "Processing, please do not move the camera". The real-time performance is not good. In addition, it often takes a certain amount of time to synthesiz...
