Embodiment 1

[0090] An embodiment of the present invention provides an image screening method, which can be applied to an image screening device, and the image screening device can be a part of a photographing device, or can be a separate device. For example, the image screening device may further have a mobile terminal with a shooting function, a camera, and the like.

[0091] like image 3 As shown, the image screening method may include:

[0092] Step 301. Acquire all images within a preset range.

[0093] Here, the preset range may be an image range delimited by the user, or a specific folder. For example, when the user needs to clean up the photos taken, the folder (album) where the photos are stored is used as the preset range; the user uses images of a period of time as the preset range; the user manually marks the group of pictures that need to be filtered as the preset range . This embodiment does not limit the preset range.

[0094] Step 302: Perform edge detection on each i...

Embodiment 2

[0119] An embodiment of the present invention provides an image screening method, assuming that the method is applied to a smart phone with a shooting function, such as Figure 5 As shown, the method may include:

[0120] Step 401: Receive an operation instruction for filtering images input by a user.

[0121] The operation instruction can be that when the memory of the smart phone is insufficient, the smart phone generates and displays information prompting the user to clear the memory. After the user chooses to clear the memory information, the cleaning options will pop up, such as cleaning useless files, cleaning installation packages, and cleaning images. Click to clean up the image, and the smartphone will receive the operation instruction to filter the image. It is worth noting that the user may actively input the operation instruction, or the mobile terminal may actively generate the operation instruction when the available memory of the smart phone is insufficient. Th...

Embodiment 3

[0137] An embodiment of the present invention provides an image screening device 50, such as Figure 10 As shown, the device 50 may include:

[0138] The acquiring unit 501 is configured to acquire all images within a preset range.

[0139] The detection unit 502 is configured to perform edge detection on all the images to obtain the edges of all the images and the edge sharpness of the edges. .

[0140] The deleting unit 503 is configured to delete the at least one image when each image has at least one edge sharpness lower than the standard edge sharpness.

[0141] In this way, the user does not need to manually delete blurred images one by one, but the image screening device automatically detects the edge of each picture, compares the edge sharpness of the detected edge with the standard sharpness, if it is lower than the standard The sharpness indicates that there is a blurred part in the picture. Therefore, the image is considered to be a blurred image, and the image i...

Abstract

The embodiment of the invention discloses an image screening method. The method comprises the steps of acquiring all images in the preset range; carrying out edge detection on the all images, thus obtaining the edges of all the images and the edge acutance which is used for representing the fuzzy degrees of the images; and in at least one image, deleting at least one image when the edge acutance of at least one edge of each image is lower than the standard edge acutance. The embodiment of the invention also discloses an image screening device.

Description

technical field [0001] The present invention relates to image processing technology, in particular to an image screening method and device. Background technique [0002] With the development of mobile terminals, the camera function of the mobile terminal is an indispensable function in people's daily life. Generally, the user first takes pictures of the scenery or characters through the mobile terminal, and then deletes the unsatisfied photos after the shooting is finished. Among these unsatisfactory pictures, the first ones to be deleted are blurred pictures that are the least meaningful to the user. However, it is a mechanical and boring process to filter blurred pictures one by one with the user's naked eyes, which greatly wastes the user's time. Contents of the invention [0003] In order to solve the above technical problems, the embodiments of the present invention expect to provide an image screening method and device, which can automatically delete blurred images...
