Embodiment 1

[0032] figure 1 It is a flow chart of the steps of an image processing method provided in Embodiment 1 of the present invention, such as figure 1 As shown, the method can be applied to a mobile terminal, and the method can include:

[0033] Step 101, if a shooting operation is received, acquire the target video shot by the mobile terminal.

[0034] In the embodiment of the present invention, the shooting operation may be sent by the user to the mobile terminal by triggering the shooting function of the mobile terminal. The specific triggering method can be triggered by clicking the camera button on the display interface of the mobile terminal, or can be triggered by a physical button. For example, when the mobile terminal is a mobile phone, the user can trigger the shooting function of the mobile phone by pressing the volume key of the mobile phone, and then send a shooting operation to the mobile phone, which is not limited in the embodiment of the present invention.

Abstract

The invention provides an image processing method and a mobile terminal, and belongs to the technical field of mobile terminals. The mobile terminal may acquire a target video according to the received photographing operation, then extract images included in the target video to obtain a plurality of candidate images, acquire portrait features in each frame of the candidate images, select a frame of image from the candidate images as the target image, adjust the portrait feature region in the target image based on the portrait features in each frame of the candidate images, and determine the adjusted target image as the final image. In this way, the final image may be guaranteed to be a better image in the target video. Compared with the prior art, the mode that the final frame of image ofthe target video is directly used as the final image makes the final image more conform to the user's expectation, thereby improving the display effect of the final image.

Description

technical field [0001] The invention belongs to the technical field of mobile terminals, and in particular relates to an image processing method and a mobile terminal. Background technique [0002] With the continuous development of mobile terminal technologies, it has become a common phenomenon for users to take pictures with mobile terminals. In order to improve the user's camera experience, dynamic shooting technology has gradually entered the user's field of vision. The terminal can take an image when the user triggers the shooting function (for example, press the shutter button), and obtain the video within the preset duration before the image is taken, and then use the image, that is, the last frame of the obtained video The image is the final image displayed, and the image and the video form a dynamic image. The user can control the terminal to play the video by selecting the displayed final image, so that the user can see the captured content vividly. [0003] How...
