In step S101 , after the camera is started, the latest captured image is displayed in the thumbnail preview window in the shooting mode.

Here, in the shooting mode, the shooting interface may include a viewfinder window, a thumbnail preview key, a tone adjustment key, a shooting operation key, and the like. The thumbnail preview window is used to display a small image of the image captured last time; it can also be set as an album cover in the smart device, and the album cover can be automatically updated to the image captured last time. Exemplarily, the thumbnail preview window may be set at a specified position such as the lower left corner, the lower right corner, the upper left corner, or the upper right corner of the viewfinder window. Whenever the camera finishes shooting, the captured image is saved to the photo album, and the image displayed in the thumbnail preview window is updated as the captured image for the user to preview.

In step S102, if a press operation acting on the thumbnail preview window is detected, the duration of the press operation is acquired.

In the embodiment of the present invention, the smart device detects the pressing operation on the thumbnail preview window in real time in the shooting mode, and counts the duration of the pressing operation until the pressing operation ends. Here, the pressing operation includes but not limited to single-point pressing or multi-point pressing. When it is a single-point press, the press operation may be a press operation of any finger on the thumbnail preview window. When it is a multi-point press, the press operation may be a press operation of any two or more fingers on the thumbnail preview window.

In step S103, when the duration is greater than or equal to a preset threshold, the image is displayed in the viewfinder window.

Exemplarily, the preset threshold may be 2 seconds. In the process of counting the duration of the press operation, if the duration is greater than or equal to the preset threshold, indicating that the current user is long pressing the thumbnail preview window, the thumbnail image will be retrieved from the album The displayed image is shown in the viewfinder window. Among them, the size of the image displayed in the viewfinder window is larger than the size of the image displayed in the thumbnail preview window, thus completing the large-scale view of the captured image, simplifying the operation of viewing the captured image, and without loading the photo album, Realized fast large image preview.

For ease of understanding, FIG. 2 shows a schematic diagram of displaying an image obtained last time in a viewfinder window according to an embodiment of the present invention. Among them, (a) represents a thumbnail preview window, and (b) represents a viewfinder window.

In step S304, if it is detected that the pressing operation ends, return to the shooting mode, and display the image captured by the camera lens in the viewfinder window.

As another preferred example of the present invention, on the basis of the embodiment in Figure 1 or Figure 3, the method may further include:

During the process of displaying the latest captured image in the viewfinder window, if a sliding operation from the thumbnail preview window is detected, the image is deleted from the photo album.

Here, during the pressing process, if it is detected that the user generates a preset sliding operation while pressing, the image will be deleted from the album. Wherein, the sliding operation includes but not limited to single-point sliding or multi-point sliding. When it is a single-point slide, the slide operation may be a slide operation performed by any finger from the thumbnail preview window. When it is a multi-point press, the sliding operation may be a sliding operation performed by any two or more fingers from the thumbnail preview window. Exemplarily, the trajectory of the sliding operation may be a straight trajectory, a curved trajectory, a clockwise circular trajectory or a counterclockwise circular trajectory, etc., which is not limited here. The embodiment of the present invention deletes the image by detecting the user's sliding operation when viewing the last captured image, which further facilitates the user's deletion operation. Only continuous long pressing and sliding can realize the acquisition of the captured image. View and delete images.

Further, if the thumbnail preview window is an album cover in the smart device, after deleting the image from the album, the method further includes:

Updates the image displayed in the thumbnail preview window.

Exemplarily, after the latest captured image is deleted, the latest captured image stored in the album is the image captured before the deleted image, here is the image obtained from the previous capture. Therefore, the thumbnail preview window is updated to the image obtained from the previous capture.

Fig. 4 shows the implementation process of the image preview method provided by another embodiment of the present invention. Referring to Figure 4, the method includes:

In step S401 , after the camera is started, the latest captured image is displayed in the thumbnail preview window in the shooting mode.
