Or suggest the order. In the description of the embodiments of the present invention, "a plurality" means two or more.

The term “and/or” in the embodiment of the present invention is merely an association relationship describing an association object, indicating that there may be three relationships, for example, A and/or B, which may indicate that A exists separately, and A and B, there are three cases of B alone. In addition, the character "/" in this article generally indicates that the contextual object is an "or" relationship.

The embodiment of the invention provides an image processing method for solving the problem that the user has difficulty in determining the image quality after the image is captured, and the power consumption of the terminal device is large. Referring to FIG. 1, the image processing method includes:

Step 101: Determine feature parameters of an image collected by the terminal device.

The characteristic parameter is a parameter that represents a shooting effect of the image, and may be, for example, a sharpness parameter, a brightness parameter, a contrast parameter, an exposure parameter, a jitter parameter, a noise parameter, a saturation parameter, a grayscale performance parameter, and a white Balance parameters, etc. In a specific implementation, the feature parameters of the image may be one or more, and the embodiment of the present invention does not specifically limit the present invention.

Step 102: Determine whether the value of the feature parameter is within a predetermined range.

Corresponding to step 101, when there is only one feature parameter of the determined image, it is determined whether the value of the feature parameter is within a predetermined range corresponding to the feature parameter; when it is determined that the feature parameter of the image is multiple, respectively Determine whether the value of each feature parameter is within its corresponding predetermined range.

For example, if the feature parameter of the image is only one of the sharpness parameter, the value of the sharpness parameter is K1, and the predetermined range of the sharpness parameter is the first preset range [a, b], then step 102 specifically includes: determining K1 Whether it is in the range [a, b].

For another example, assume that the characteristic parameters of the image have three parameters: a sharpness parameter, a brightness parameter, and a contrast parameter, and the values are respectively K1, K2, and K3; wherein the predetermined range of the sharpness parameter is the first preset range [a, b) The predetermined range of the brightness parameter is the second preset range [c, d], and the predetermined range of the contrast parameter is the third preset range [e, f]; correspondingly, the step 102 specifically includes: determining whether the K1 is in the range [ In a, b], whether K2 is in the range [c, d], and whether K3 is in the range [e, f].

Step 103: Generate a thumbnail with a preset mark for the image if the value of the feature parameter is within the predetermined range.

In the specific implementation process, the foregoing image processing method may be, but is not limited to, being applied to a screen capture or a screen processing process of a media file, where the media file may include, but is not limited to, a video, a motion picture, a photo, and the like. Correspondingly, in the image processing method, the image collected by the terminal device may be, but is not limited to, at least one of the following: a video frame picture, a moving picture frame, and a photo picture. The above is only an example, and is not limited in this embodiment.

In the specific implementation process, the preset mark may be implemented in various manners, such as an icon, a text, and the like, which are not specifically limited in the embodiment of the present invention. For example, when the feature parameter is the sharpness parameter, a red border may be added on the thumbnail of the image with low definition; for example, when the feature parameter is the exposure parameter, yellow may be added to the image thumbnail with high exposure. A pentagram icon; for example, when the feature parameter is a jitter parameter, the text "jitter" can be added to the thumbnail image of the image with high jitter.

Of course, in a specific implementation process, if the value of the feature parameter of the image is not within the predetermined range corresponding to the feature parameter, the corresponding thumbnail may be generated for the image, but the generated thumbnail has no preset mark.

For example, referring to FIG. 2, assuming that the feature parameter is sharpness, and the predetermined range is less than the preset value, if the user does not reach the preset value after the user takes a photo using the mobile phone, the generated thumbnail has a map. The "red border" mark shown in 2 indicates that the sharpness of the image does not reach the preset value, as shown in the lower right corner of Fig. 2; if the sharpness of the image reaches the preset value, the generated thumbnail is not There will be this flag, as shown in Figure 3.

In the above solution, after the image is captured by the terminal device, if the value of the feature parameter of the image is within a predetermined range, the generated thumbnail has a preset mark. In this way, the user can perform operations such as switching the display interface, opening the image, and the like after directly capturing the image, and directly checking whether the thumbnail of the image captured on the shooting interface has a preset mark, thereby determining the quality of the image. The time is short and no operation is required, which improves the user experience. At the same time, for the terminal device, there is no need to respond to the user to switch the display interface, open the image, etc., thereby reducing the power consumption of the device.

Optionally, after generating the thumbnail with the preset mark for the image, the method further includes: receiving, when the thumbnail is displayed, a deletion operation input by the user for the thumbnail; in response to the Delete the operation and delete the image.

For example, referring to FIG. 2, after the terminal device collects an image, the shooting interface displays a thumbnail of the image that was last captured, and a preset mark is displayed on the thumbnail of the image, and the user can directly delete the thumbnail of the image, and During the deletion process, a window asking the user whether to confirm the deletion of the image does not pop up, but directly responding to the user operation, and deleting the image from the terminal device, thereby realizing quick deletion of the image whose feature parameter is within a predetermined range.

In a specific implementation process, the deleting the thumbnail may be a touch thumbnail, such as a user clicking a thumbnail of the image with a finger. Further, the deleting operation may further be: the user touches the thumbnail according to a preset policy, for example, the duration of the touch thumbnail is greater than the first preset value, and/or, when the thumbnail is touched, the terminal device is generated. The pressure is greater than the second preset value.

Optionally, in a specific implementation process, when determining that the feature parameter of the image is within a predetermined range, in addition to displaying the thumbnail of the preset mark on the shooting interface as described above, the thumbnail may be retained in the album. Preset mark.

For example, referring to FIG. 4, there is a thumbnail of six photos in the album, wherein the value of the brightness parameter of one photo is lower than the preset brightness value, then a preset mark is displayed on the thumbnail corresponding to the photo, the preset The mark is indicated by a black border in the figure, such as the second photo on the second line.

Optionally, the user can perform a delete operation on the thumbnail image with the preset mark on the album interface, so as to quickly delete the image, such as the user clicking the thumbnail of the image with a finger, or touching the thumbnail according to a preset policy.

Alternatively, the user may also perform an operation of bulk deleting the image whose value of the feature parameter is within a predetermined range in the album interface. For example, after the terminal device receives the batch deletion of the user input, all the images with the preset mark in the thumbnail of the terminal device are filtered out and deleted from the terminal device.

Optionally, in combination with the foregoing multiple implementation manners of the preset mark, when there are at least two types of preset tags in all the images saved by the terminal device, the image may be more accurately determined according to the type of the preset mark. Filter, batch delete and other operations. For example, in the terminal device, the sharpness has a red wire frame mark on the thumbnail of the image of the first preset range, and the brightness has a red heart mark on the thumbnail of the image of the second preset range, then the user can Filter out images with red wireframe markers and batch delete all images with red wireframe markers, or filter out images with red heartmarks and batch delete all images with red heartmarks, or filter out unmarked images And delete all unmarked images in bulk.

In this manner, the user can determine the quality of each image by recognizing the thumbnail of each image in the album, and perform a delete operation on the thumbnail of the image with poor quality to achieve the effect of quickly deleting the image with poor quality, minus Small device power consumption.

Moreover, the image corresponding to the thumbnail with the preset mark can be deleted in batches, so that the user can manage the image more conveniently, thereby further improving the user experience.

Optionally, after generating the thumbnail with the preset mark for the image, the method may further include: saving the image in a preset folder.

Specifically, the thumbnail image with the preset mark and the image with the thumbnail without the preset mark are respectively saved in different folders, thereby realizing the classification and saving, thereby enabling the user to quickly find all the poor quality images by searching the folder. Then manage it, such as batch deletion of poor quality photos.

In the specific implementation process, the specific implementation manner of the preset folder may be multiple, and the embodiment of the present invention does not specifically limit. For example, the preset folder may be a main album or an album for deletion or collection.

In combination with the foregoing implementation manners of the preset tags, when there are at least two types of preset tags in all the images saved by the terminal device, different types of preset folders may be established for different types of preset tags. .

For example, the terminal device may add a red wire frame mark on the thumbnail of the image whose definition is lower than the preset value X and/or the brightness is lower than the preset value Y, and the image with the sharpness higher than X and the brightness higher than Y The green wire frame mark is added to the thumbnail, the red wire frame mark image is saved in the first preset folder (for the deleted album), and the green wire frame marked image is saved in the second preset folder. (main album). The second preset folder has a function of triggering the deletion of the mark, that is, the user can perform a touch operation on the thumbnail with the green wire frame mark, and delete the corresponding image; the first preset folder has a one-click delete function. , that is, the user can perform an input operation to delete all the images in the first preset folder.

Optionally, in a case that the value of the feature parameter is located within the predetermined range, the method may further include: generating a thumbnail for the image without a preset mark; receiving the user input for the none a mark operation of a thumbnail of a preset mark; in response to the mark operation, adding the preset mark on the thumbnail having no preset mark.

For example, after the user takes a photo using the terminal device, the feature parameter of the photo is not within the predetermined range, and the generated thumbnail has no preset mark. However, the user still thinks that the quality of the photo is not good, then the user can touch the thumbnail of the image on the shooting interface and keep the touch operation for more than the third predetermined time, and then manually add the pre-image to the thumbnail of the image. A flag is set, and when the subsequent terminal device performs an operation of classifying, deleting, or the like on the image, the image is recognized as an image whose feature parameter satisfies the predetermined range.
