The image previewing method, the image previewing device and the electronic equipment provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of an image preview method according to an embodiment of the present application, as shown in fig. 1, the image preview method may include the following steps:
and 101, under the condition that a thumbnail window is displayed on a shooting preview interface, receiving a first input of a user to the thumbnail window, wherein the thumbnail window comprises a thumbnail image of a first visual object.
The first visual object may be a visual object such as a picture, a photo, a video, a moving image, etc., and for convenience of explanation, the description will be given by taking the first visual object as a still image as an example.
In addition, the receiving the first input of the user to the thumbnail window (which may also be referred to as a thumbnail window) may be that the user performs the first input by hand, or that the user performs the first input using a stylus or the like.
Further, the first visual object is an image shot in a preset time period.
The preset time may refer to an image that is last shot, or a preset time before the current time, for example: images taken within 5s (seconds).
The method and the device can be applied to application scenes in which a user shoots a plurality of images and needs to shoot subsequent images according to shooting effects of the images shot recently, at this time, the user can conveniently preview the shooting effects of the images by displaying the images shot in a preset time in a shooting preview interface, so that parameters such as shooting angles, focal distances and the like are adjusted.
And 102, responding to the first input, and displaying a preview window on the shooting preview interface, wherein the preview window comprises a preview image of the first visual object, and the size of the preview image is larger than that of the thumbnail image.
In a specific implementation, the shooting preview interface may be a shooting preview interface displayed when the image capturing device such as a camera is started and used for previewing an image captured by the camera. The preview window may also be referred to as a quick view window, and the displaying of the preview window on the photographing preview interface in response to the first input may be understood as: a preview model (which may also be referred to as a quick view mode) is turned on, in which a preview window is displayed on a photographing preview interface to display a preview image of an image in an album within the preview window, and the preview image can be manipulated through the preview window, for example: zooming in, zooming out, switching to preview images of other images, etc., thereby facilitating the user to preview the captured visual object in the capture preview interface in the quick view mode.
In the related art, as shown in fig. 2a, a thumbnail window 21 (may also be referred to as a thumbnail mark) may be displayed at the lower left corner of the photographing preview interface 20, and a thumbnail image of a first visual object (hereinafter, simply referred to as a first image) photographed last time is displayed in the thumbnail window 21, and is small in size, and often has a width and a length of less than 1 cm, so that a user cannot recognize specific details of the first image through the thumbnail image.
The method and the device can be applied to the process that a user shoots images, the shooting effect of the first image shot recently needs to be checked on a shooting preview interface, and the shooting angle and the like are adjusted according to the shooting effect, so that the scene of the shooting effect is further improved. At this time, the user can trigger to display the preview window in the shooting preview interface only through the first input of the thumbnail window, so as to preview the first image through the preview window, and the preview image in the first preview window is larger than the size of the thumbnail image, thereby avoiding the complicated operation procedures that the user needs to enter the album to check the shooting effect of the first image, and then enter the shooting preview interface again to adjust the shooting angle according to the shooting effect of the first image.
For example: as shown in fig. 2b, when the user presses the thumbnail window 21 long, the preview window 22 is displayed in suspension in the photographing preview interface 20, and the size of the preview window 22 is larger than that of the thumbnail window 21, so that the preview image in the preview window 22 is larger than that in the thumbnail window 21, and the user can recognize the details of the first image a through the preview image, thereby realizing the preview of the first image a. In the application, a shutter button 25 may be displayed in the photographing preview interface 20, and when the user touches the shutter button 25, an image is photographed, and after photographing is completed, a preview image of the latest photographed image is displayed in the preview window 22.
It should be noted that, the first input is not limited to the long-press input of the thumbnail window, and may be one or more of double-click, double-press, sliding and other touch inputs, and may even be a long-press, continuous multiple-press operation of a hardware button on the electronic device. And in the shooting process, the shooting is not limited to shooting an image by touching the shutter button 25, and can be triggered by using a time delay shutter or the like in the case of displaying the preview window 22.
In addition, the size of the preview image is larger than that of the thumbnail image, which can be understood as:
The preview image has an initial size larger than that of the thumbnail image, for example: in the case of receiving the first input of the user to the thumbnail window, a photographing preview interface 20 as shown in fig. 2b is displayed, the size of the preview image in the photographing preview interface 20 may be equal to the size of the preview window 22, the initial size of the preview window 22 may be 1/3 of the size of the photographing preview interface 20, and the length and width of the thumbnail window 21 may be only 1 cm, respectively, so that it is seen that the initial size of the preview window 22 may reach 5 to 10 times the size of the thumbnail window 21, the enlarged size may even reach more than 20 times the size of the thumbnail window 21, and the aspect ratio of the preview window 22 may be the same as the aspect ratio of the photographed visual object, thereby being more advantageous for previewing the photographed visual object than the thumbnail window 21.
In addition, the shooting preview interface is not limited to the photo shooting preview interface, but may be a video shooting preview interface, where the first image is a video, and the preview image displayed in the preview window is a video preview image.
Further, the video preview image may be understood as: the preview image of a frame of picture in the video, or the video preview image may also be a preview image of a cover image of the video, and a video identifier (for example, a video identifier 24 shown in fig. 2 c) may be displayed on the video preview image, so that the user can distinguish the video preview image from the picture preview image through the video identifier, or prompt the user to touch the video identifier, so as to play the video in the preview window.
Therefore, through shooting the preview window displayed on the preview interface, the video can be played so as to preview the shooting effect and the like of the video, a user does not need to enter an album, and the user can click to play after searching the source file of the video, so that the operation process of previewing the video is simplified.

receiving a fifth input of a user to the preview window;
and responding to the fifth input, and controlling the video in the preview window to play, pause or adjust the playing progress of the video.
In a specific implementation, in addition to at least one frame of image of the video displayed in the preview window, a play control, a pause control or a play progress adjustment control may be displayed, and the fifth input is a touch input to the play control, the pause control or the play progress adjustment control.
For example: as shown in fig. 2c, an image frame a of a video is displayed in the preview window, and a play control 24 is further displayed above the image frame a, so that a user can control to play the video in the preview window by clicking the play control 24.
Of course, in practical applications, the play control, pause control, or play progress adjustment control may be hidden. For example: if the click touch operation is executed in the preview window for the first time, playing the video in the preview window; if the click touch operation is executed again in the preview window, pausing the video played in the preview window; if the rightward sliding operation is executed at the lower end in the preview window, the playing progress of the video in the preview window is controlled to advance; and if the left sliding operation is executed at the lower end in the preview window, controlling the playing progress of the video in the preview window to be backed.
The method and the device can be applied to the shooting effect of a user in the shooting process, the shooting effect of the recently shot video is needed to be checked on the shooting preview interface, the shooting angle is adjusted according to the shooting effect, and the like, so that the scene of the shooting effect is further improved, at the moment, the user does not need to exit the shooting preview interface, but can control the video in the preview window to play, pause or adjust the playing progress of the video through the fifth input of the preview window, and therefore the comprehensive preview of the video is realized, and the operation process of previewing the recently shot video in the shooting process can be simplified.
Optionally, the first visual object is a visual object collected by a first camera, and the main preview window of the shooting preview interface includes a preview image of a fourth visual object collected by a second camera.
In a specific implementation, a plurality of cameras may be turned on to respectively collect images at different angles, for example: the electronic equipment comprises a front camera and a rear camera, wherein in the process of simultaneously starting the front camera and the rear camera to shoot, shooting preview images of one camera can be displayed in a preview window, shooting preview images of the other camera are displayed in a main preview window, and the preview window is displayed on the main preview window in a floating mode.
The method and the device can be applied to the process of starting at least two cameras to shoot respectively, and the application scene of shooting effects of the at least two cameras needs to be checked on the shooting preview interface at the same time, at this time, preview images of fourth visual objects acquired by the second cameras are displayed on a main preview interface in the shooting preview interface, preview images of first visual objects acquired by the first cameras are displayed in the preview interface, and a plurality of image acquisition devices can be previewed respectively, so that a picture-in-picture shooting preview mode is realized.
Further, in practical applications, the image preview method provided in the present application may be further applied to an application scenario in which scaling, shrinking, deleting, moving, switching, and viewing local details need to be performed on an image that has been shot in a process of shooting preview, where a user may implement, through input of a preview window or a preview image, an operation on the thumbnail window, the preview image in the thumbnail window, or a first visual object corresponding to the preview image, for example: for details in zooming the thumbnail window, moving the thumbnail window, closing the thumbnail window, enlarging the details in the preview image, switching the preview image or deleting the first image, etc., reference may be made to the following embodiments:
optionally, in response to the first input, after displaying a preview window on the shooting preview interface, the method further comprises:

and responding to the first touch input, and displaying a local amplification window, wherein the local amplification window comprises a local amplification image, and the local amplification image is an image in which the image in the first area is amplified by a preset proportion.
In a specific implementation, the first touch input may be a click or slide touch input on the preview image, and at this time, the first area may be understood as: and a part of the preview image overlapped with the touch area of the first touch input or a part of the preview image positioned in a preset range near the touch area.
In addition, the above-mentioned display local zoom-in window (which may also be referred to as a "zoom-in frame") may be a floating display local zoom-in window in the shooting preview interface, and specifically, may be a floating display zoom-in frame at a position on the preview image near the touch area, so as to display the zoomed local zoom-in image in the zoom-in frame, for example: as shown in fig. 2d, when the user touches the touch area of the preview image with his finger, the magnifying glass frame 23 is displayed at a display position adjacent to the touch area, and the magnified partial magnified image is displayed in the magnifying glass frame 23.
The preset ratio of the local enlarged image enlargement may be a fixed preset magnification, or the magnification may be a magnification set by the user through a setting operation, which is not particularly limited herein.
When the finger of the user moves in the preview image, the magnifying glass frame 23 also moves along with the touch position, and the magnified partial magnified image displayed in the magnifying glass frame 23 also updates the displayed image content along with the change of the touch position. When the user's finger slides out of the preview image, closing of the magnifying glass frame 23 may be triggered.
In this embodiment, the method is applied to an application scenario in which a user needs to enlarge and view details of a shot image in a shooting process, at this time, an enlarged touch area can be displayed through a first touch input of a preview image, so that the user can preview details of the first image, and can find problems of the first image in time, thereby adjusting shooting parameters.
Optionally, in response to the first input, after displaying a preview window on the shooting preview interface, the method further comprises:
Receiving a first sliding input of a user to the preview window;

wherein the second visual object is determined based on the sliding direction, the first size being larger than an original size of the second visual object.
The first sliding input may be a sliding input along a lateral direction or a longitudinal direction, and the touch position of the first sliding input may be always located in the preview interface. In addition, the second visual object and the first visual object may be located in the same album, and a preset number of visual objects are adjacent to or spaced from each other.
In a specific implementation, when the preview window is opened through the first input to the thumbnail window, the preview image displayed in the preview window may be a preview image of a first visual object arranged at the top or last shot in the album. The method and the device can be applied to an application scene that a user needs to preview other images when the user continuously shoots a plurality of images, and at this time, the user can update the preview images displayed in the browse window through the first sliding input of the preview window.
It should be noted that, the second visual object is determined based on the sliding direction, and may be understood as:
the second visual object associated with a different sliding direction is different from the first visual object in the album.
For example: as shown in fig. 2e, when the user's finger slides rightward in the preview window 22, the preview image in the preview window 22 may be switched to the preview image of the second image B arranged before the first image a in the album.
Of course, when the finger of the user slides leftward in the preview window, the preview image in the preview window may be switched to the preview image of the second image C arranged after the first image a in the album.
In practical applications, the sliding direction of the first sliding input may be upward, downward, or the like, which is not particularly limited herein.
According to the embodiment, the previews previewed in the preview window can be updated by the first sliding input of the preview window, so that the user does not need to enter the album to view other images except the first visual object, and the convenience of viewing other preview images can be improved.
Optionally, in response to the first input, after displaying a preview window on the shooting preview interface, the method further comprises:
Receiving a second input of a user to the preview window;
in response to the second input, the display size of the preview window is enlarged or reduced.

Of course, the user can also enlarge the display size of the preview window by moving the two touch points within the preview window away from each other.
In addition, the zoom-out magnification of the display size of the preview window may be positively correlated with the moving distance of the two touch points in the preview window, and the zoom-in magnification of the display size of the preview window may be positively correlated with the moving distance of the two touch points in the preview window away from each other.
In this embodiment, the size adjustment of the preview window may be achieved through the second input to the preview window, so as to improve the flexibility of the preview window.
In addition, the preview image may cover the entire display area of the preview window, so that the size of the preview image may be enlarged or reduced by enlarging or reducing the display size of the preview window, so that the user may adjust the size of the preview image to a size that facilitates the preview of the first image through the second input according to the actual condition of the first image.
Optionally, in response to the first input, after displaying a preview window on the shooting preview interface, the method further comprises:
receiving a second sliding input of a user to the preview window, wherein an input initial position of the second sliding input is at least partially overlapped with the preview window;
and responding to the second sliding input, and moving the preview window to a display position where an input end position of the second sliding input is located.
In a specific implementation, the input starting position of the second sliding input at least partially overlaps the preview window, which may be understood as: the input initial position of the second sliding input may be located on a frame of the preview window, and the input final position of the second sliding input is located outside the preview window.
In practical application, during the process of moving the preview window, the preview window may be further highlighted, so that the user is prompted to slide a finger to move the preview window through the highlighted display state. For example: when it is detected that a touch point is located on the frame of the preview window and the touch time is longer than a preset time (for example, 1 second), the preview window may be highlighted. For another example: as shown in fig. 2g, the display color of the frame of the preview window 22 is adjusted, and by highlighting the preview window, the user may be prompted to slide a finger to move the preview window 22, at this time, after highlighting the preview window 22, if the user slides the finger in the capturing preview interface 20, the preview window 22 may be moved along the sliding track of the second sliding input.
Of course, in an implementation, the highlighting of the preview window may also be adjusting a display parameter (e.g., brightness, gray scale, transparency, etc.) of the preview window, which is not specifically limited herein.
In this embodiment, the display position of the preview window may be adjusted by the second sliding input to the preview window, so as to implement convenient movement of the preview window. Furthermore, when the preview window is displayed on the main preview window of the shooting preview interface, the user can conveniently move the preview window so as to reduce the shielding of the preview window on the main preview window.
Optionally, in response to the first input, after displaying a preview window on the shooting preview interface, the method further comprises:
receiving a third sliding input of a user to the preview window, wherein the third sliding input takes the preview window as a sliding starting point and takes the thumbnail window as a sliding ending point;
and closing the preview window and exiting the preview mode in response to the third sliding input.
The third sliding input takes the preview window as a sliding starting point and takes the thumbnail window as a sliding end point, which can be understood as: the sliding starting point of the third sliding input is positioned in the preview window, and the sliding ending point of the third sliding input is positioned in the thumbnail window.
In an embodiment, the preview mode indicates that the preview window is displayed in a photographing preview interface to realize a mode of previewing a photographed image in the photographing preview interface, and the preview mode is entered when the first input to the thumbnail window is received corresponding to the exit preview mode. In addition, after closing the preview window, an interface as shown in fig. 2a may be displayed.
In this embodiment, the method and the device can be applied to an application scenario that needs to exit from a preview mode after a captured image is previewed in a capturing process, and at this time, a user can conveniently close the preview window through a third sliding input, so that after the preview window is closed, the user can conveniently view capturing contents in a capturing preview interface, or operate the capturing preview interface to adjust capturing parameters and the like.
Optionally, in response to the first input, after displaying a preview window on the shooting preview interface, the method further comprises:
receiving a sixth input of a user to the preview image;
in response to the sixth input, the first visual object is displayed full screen.
In a specific implementation, the sixth input may be a touch input, for example: the sixth input may be a pressing operation of hardware on the electronic device, and is not particularly limited herein.
In addition, the full-screen display of the first visual object may be an original image of the full-screen display of the first visual object, for example: entering an album, and opening and displaying the first visual object full screen in the album, for example: as shown in fig. 2h, the first image a is displayed full screen.
In this embodiment, the method and the device can be applied to an application scene that needs to enter an album to view or process a first visual object after shooting is completed, and at this time, a user can trigger the first visual object displayed in full screen conveniently through a sixth input, so that the user views or processes the first visual object.
Optionally, in response to the first input, after displaying a preview window on the shooting preview interface, the method further comprises:
receiving a fourth input of a user to the preview window;
in response to the fourth input, the first visual object is deleted and a preview image of a third visual object is displayed within the preview window.
In a specific implementation, the fourth input may be a touch input, for example: the fourth input may be a pressing operation of hardware on the electronic device, and is not particularly limited herein.
Further, the fourth input is used for dragging the preview window to an input in a preset display area, and in the process of dragging the preview window, a deletion control is displayed in the preset display area. For example: in the case that the fourth input is a sliding input from the preview window 22 to the top area 201 of the photographing preview interface 20 as in fig. 2i, the fourth input is the same as the second sliding input for moving the preview window 22, except that: the sliding end point of the fourth input is located in the top area 201 of the photographing preview interface 20, or during the sliding of the finger of the user, the preview image of the first image a moves along with the finger of the user, so as to move the preview image of the first image a to at least partially overlap with the top area 201. Furthermore, in the process that the preview image of the first image a moves along with the finger of the user, the transparency of the preview image of the first image a can be improved, so that the preview image of the first image a is in a semitransparent state. Moreover, when the finger of the user slides into the top area 201 of the shooting preview interface 20 or the preview of the first image a moves to at least partially overlap with the top area 201, a delete icon 202 may be displayed in the top area 201 to prompt the user to drag the preview in the preview window 22 to overlap with the delete icon 202, so that deletion of the first image a may be achieved. And after deleting the first image a, a preview image of a third image B is displayed within the preview window 22.
Of course, in the implementation, the fourth input may also be other touch input, for example: the fourth input is an input for reducing the preview window to be less than or equal to a preset size. The preset size may be 20% of the initial size of the preview window, etc., and is not particularly limited herein. At this time, the user may zoom out the preview window by performing double-throw and close touch input in the preview window, and when the preview window is zoomed out to be smaller than or equal to a preset size, the user stops the touch operation, and then the first visual object may be deleted from the album.
In addition, the third visual object may be an image in the same album as the first visual object. For example: the third visual object and the first visual object are in the same album and are arranged behind the first visual object.
In this embodiment, the method and the device can be applied to an application scenario in which when a large image is not ideal and needs to be deleted, at this time, a user can delete an original image corresponding to a preview image displayed in the preview window conveniently through a fourth input to the preview window and update the preview image displayed in the preview window, and the image can be deleted without entering an album, so that convenience in original image deletion operation is improved.
