The specific flow of the image display method provided by this embodiment may be as follows:

and S101, scanning the image of the photographing visual field area of the mobile terminal to obtain a scanned image.

In this embodiment, this step is the basis of all subsequent operations, and is intended to store the picture (i.e. the scanned image) captured by the lens of the terminal device into the processor of the terminal device and display the picture in the preview interface of the terminal device. The picture captured by the lens of the terminal equipment comprises an object which a terminal user wants to shoot and other objects.

It is easy to understand that, when the preview interface of the terminal displays the picture captured by the terminal lens, the size of the preview interface can be set according to a preset display scale. The display scale is used for indicating the size relation between the preview interface and the terminal display screen. For example, if the display ratio is 70%, it indicates that the size of the preview interface is 70% of the size of the display screen.

S102, determining at least one shot object from the scanned image, and extracting a partial image of each shot object from the scanned image.

And S103, in the image scanning process, when the position of the mobile terminal is detected to be changed, displaying a composite image containing the shot object on the current preview interface according to the local image.

Further, the step S102 may specifically include:

determining all objects in the scanned image, and displaying the scanned image on the current preview interface;

acquiring selection operation information of a user on a preview interface;

determining at least one photographed object from all objects according to the selection operation information;

acquiring continuous frame scanning images within a preset time length;

and extracting the corresponding image with the highest definition of each object from the continuous frame scanning images as a local image of the corresponding object.

In this embodiment, after the terminal determines all objects in the scanned image of the terminal through the sensing element inside the terminal, a corresponding mark may be added to each object on the scanned image for the user to select in the subsequent operation, and the scanned image including the mark is displayed on the current preview interface. It will be readily appreciated that the manner in which the respective indicia is added to each object in the scanned image includes, but is not limited to: a selection box is generated on each object and/or a marker point is generated on each object.

Specifically, the user may trigger the electronic device to generate the selection operation information by clicking a mark corresponding to the object displayed on the preview interface, or by specifying a gesture, voice, or the like. If the user triggers the electronic equipment to generate selection operation information by clicking a mark corresponding to the object displayed on the preview interface, the processor determines that the object corresponding to the mark selected by the user is taken as a shot object; if the user triggers the electronic equipment to generate selection operation information through the designated gesture, the processor determines an object contained in a range covered by the designated gesture as a shot object; if the user triggers the electronic equipment to generate the selection operation information through voice, the processor determines the shot object according to the information contained in the voice, wherein the information contained in the voice indicates the shot object selected by the user.

After the processor obtains the definition scores of each shot object under each frame, the corresponding image with the highest definition score is selected as the local image of the corresponding shot object, and the rest images are deleted from the cache area for storing the images.

Further, the step S103 may specifically include:

when the target scanning image contains the shot object, determining the position of the shot object on the target scanning image as a target position;

and generating a composite image containing the shot object at the target position according to the local image, and displaying the composite image on the current preview interface.

In this embodiment, when the position of the mobile terminal changes, the subject may not be in the current photographing field of view at all, or only a part of the subject may be in the current photographing field of view. When the shot object is possibly not in the current shooting visual field area at all, the target scanning image is considered not to contain the shot object; when only a part of the object is in the current photographing field of view, the object is considered to be included in the target scanning image. When only one part of the shot object is in the current shooting visual field area, the processor firstly determines the part of the shot object in the current shooting visual field area as a part to be displayed, then extracts a corresponding image from the local image according to the part to be displayed, then generates a composite image containing the part to be displayed at a target position, and displays the composite image on a current preview interface.

Specifically, the step "in the process of image scanning" further includes:

and when the difference value between the two pieces of position information is not less than the preset difference value, determining that the position of the mobile terminal is changed.
