Embodiment 1

[0035] refer to figure 1 , which shows a flow chart of an embodiment of an image processing method of the present invention, which may specifically include the following steps:

[0036] Step 101. Determine the target image area in the photo preview interface.

[0037] Usually, users only have relatively high requirements for the clarity of some areas in the image. For example, in a photo taken of a person, the user may hope that the part of the person in the image can be clearer, but does not have high requirements for the clarity of the background. In order to save storage space, in the image data captured by the mobile terminal, the definition enhancement processing may be performed only for a specific area, such as a partial area of ​​interest to the user. The mobile terminal may determine a specific area in the image data when shooting, for example, a part of a person in a person image as the specific area.

Embodiment 2

[0049] refer to figure 2 , which shows a flow chart of another image processing method embodiment of the present invention, which may specifically include the following steps:

[0050] Step 201. Determine the target image area in the photo preview interface.

[0051] Usually, users only have relatively high requirements for the clarity of some areas in the image. For example, in a photo taken of a person, the user may hope that the part of the person in the image can be clearer, but does not have high requirements for the clarity of the background. In order to save storage space, in the image data captured by the mobile terminal, the definition enhancement processing may be performed only for a specific area, such as a partial area of ​​interest to the user. The mobile terminal may determine a specific area in the image data when shooting, for example, a part of a person in a person image as the specific area.

Embodiment 3

[0101] refer to Figure 7 , which shows a structural block diagram of a mobile terminal embodiment of the present invention, which may specifically include the following modules:

[0102] The area determination module 701 is configured to determine the target image area in the photo preview interface.

[0103] The image acquiring module 702 is configured to acquire at least two frames of images of the same resolution continuously captured by the camera for the same shooting scene after receiving the photographing instruction.

[0104] An image extraction module 703, configured to extract an image corresponding to the target image area determined by the area determination module in the at least two frames of images acquired by the image acquisition module.

[0105] An image generation module 704, configured to generate a first target based on the at least two frames of images acquired by the image acquisition module and the images corresponding to the target image areas in the...

Abstract

The invention provides an image processing method and a mobile terminal. The method comprises that a target image area in a shooting preview interface is determined; after that a shooting instruction is received, at least two frames of images, of the same resolution, collected by a camera continuously of the same shooting scene are obtained; images corresponding to the target image area are extracted from the at least two frames of images; based on the at least two frames of images and the images corresponding to the target image area in the two frame of images, a first target image and a second target image are generated; and association between the first target image and the second target image is established and stored. The resolution of the second target image is higher than that of the first target image. According to the method and mobile terminal provided by the invention, the target image area in the at least two frames of images are processed, and memory resource is saved effectively.

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] Due to the portability of the mobile terminal, users more often use the mobile terminal to take pictures. As users have higher and higher requirements for the clarity and resolution of photos, the single-frame image data captured by mobile terminals can no longer meet the needs of some users. [0003] At present, the method for generating a high-resolution image is to quickly capture at least two frames of image data for the same scene when the camera is confirmed, for example, when the camera button is pressed. Composite processing is performed using at least two frames of captured image data to generate composite image data for display. However, the data volume of the synthesized image data is relatively large, generally several times the size of the single frame image data, and occ...
