no. 1 example

[0026] see figure 1 , is a flow chart of the first embodiment of the image processing method of the present invention, the image processing method is applied to a mobile terminal with a camera, and the image processing method includes:

[0027] Step 101, acquiring multiple frames of original images continuously captured by the camera.

[0028] In the embodiment of the present invention, before step 101, it further includes: receiving a user's request for starting a photographing function, and then displaying a photographing preview interface according to the request for starting the photographing function.

[0029] In the embodiment of the present invention, after the photo preview interface is displayed, the image enhancement mode request from the user is received, and then the image enhancement mode is entered according to the image enhancement mode request. Image enhancement modes include night scene mode and HDR mode, among which night scene mode is used for night scene i...

[0040] refer to figure 2 , is a flowchart of the second embodiment of the image processing method of the present invention, the image processing method is applied to a mobile terminal with a camera, and the image processing method includes:

[0041] Step 201, acquiring multiple frames of original images continuously captured by the camera.

[0042]In the embodiment of the present invention, before step 201, it further includes: receiving a user's request for starting the camera function, and then displaying a camera preview interface according to the request for starting the camera function.

[0043] In the embodiment of the present invention, after the photo preview interface is displayed, the image enhancement mode request from the user is received, and then the image enhancement mode is entered according to the image enhancement mode request. In the image enhancement mode, night scene image synthesis processing or HDR image synthesis processing can be performed.

no. 3 example

[0071] refer to Figure 3a , Figure 3a is one of the structural block diagrams of the first embodiment of the mobile terminal of the present invention, Figure 3a The mobile terminal 300 includes a camera, and the mobile terminal 300 also includes: an image acquisition module 301 , an image synthesis module 302 , an image processing module 303 , and an image compression processing module 304 .

[0072] In the embodiment of the present invention, the image acquisition module 301 is configured to acquire multiple frames of original images continuously acquired by the camera.

[0073]Specifically, before the image acquisition module 301 acquires multiple frames of original images continuously captured by the camera, the mobile terminal 300 may receive a user's camera function activation request, and then display a camera preview interface according to the camera function activation request. After the photo preview interface is displayed, the mobile terminal 300 may receive the...

Abstract

Examples of the present invention provide an image processing method and mobile terminal.This image processing method includes: to obtain the multi -frame original image collected continuously in the camera; synthesize the first intermediate image by the preset algorithm;Get the second intermediate image; perform the image compression processing of the second intermediate image to obtain the final image. Among them, the multi -frame primitive image and the first intermediate image are all RAW format images with 10 than the special.The middle image is an 8 -than -wide YUV format image, and the final image is a JPEG format image with a wide range of eights.The image processing method provided by the embodiment of the present invention can obtain a wider dynamic range, less image noise, and more image details when using a mobile terminal to synthesize and enhance the processing.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an image processing method and a mobile terminal. Background technique [0002] With the development of communication technologies, functions of mobile terminals are becoming more and more diverse. For example, many mobile terminals have a camera function. During the process of taking a photo, the user can select a photo mode corresponding to the current environment (eg, lighting, scene, etc.) to take a photo. Currently, the camera mode includes an image enhancement mode, and the image enhancement mode includes a night scene mode, a high-dynamic range (High-Dynamic Range, HDR) mode, and the like. The image enhancement algorithm is mainly implemented in the hardware abstraction layer (HAL) of the electronic device. The input data is the image data in the YUV420 format, that is, the synthetic enhancement technology is performed on multiple image data frames in the Y...
