Moreover, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.
The term "include" and variations thereof as used herein are open-ended, i.e., "including but not limited to". The term "based on" is "based, at least in part, on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions for other terms will be given in the following description.
It is noted that references to "a", "an", and "the" modifications in this disclosure are intended to be illustrative rather than limiting, and that those skilled in the art will recognize that "one or more" may be used unless the context clearly dictates otherwise.
Fig. 1 is a view of an application scenario of a focusing method according to an exemplary embodiment of the present disclosure, and as shown in fig. 1, the focusing method provided in this embodiment may be applied to a scenario in which a plurality of persons are photographed (for example, a self-portrait) by using an electronic device 100 (for example, a mobile phone).
It should be noted that, at present, when a plurality of persons take a picture, one of the face regions in the preview image is usually determined as the focusing region according to the area of the face region or the position of the face region. The preview image can be understood as an image acquired by a camera before shooting, that is, an image displayed in a display screen of a mobile phone after a user opens the camera of the mobile phone but before triggering shooting. It can be seen that the face focused by the current focusing method is completely dependent on the standing position of the photographed person.
However, the current mobile phone actually belongs to a very private article, and most people take pictures by using the personal mobile phone, especially when taking self-pictures, for example: often with friends, relatives and friends etc. the shooting action is mostly to satisfy the personal shooting requirement, i.e. the owner of the mobile phone usually wants to be in the core of the shot picture and wants the best shooting effect. However, in the current focusing method, in such a multi-person close-up scene, the focus of the camera is not on the face of the owner of the mobile phone due to standing position, posture and other factors, and the owner of the mobile phone cannot obtain the best photographing effect.
Further alternatively, when a specific object is photographed by a mobile phone, for example: when a group of specific articles (such as clothes, furniture and vehicles) need to be shot, especially when the specific articles are shot in comparison with a plurality of similar articles, the current focusing mode is to focus according to the area size or the distance of scenery, and if the focusing object is incorrect, the user needs to manually focus, which is very inconvenient.
In view of the above problems, embodiments of the present invention provide a focusing method, which includes obtaining a preview image, determining an area of a preset target image in the preview image, and focusing the determined area as a focusing area to focus a specific target object, so that the specific target has a better shooting effect in a shot image, thereby satisfying a personalized shooting requirement of a user.
The game interface testing method is described in detail below with several specific implementations. Fig. 2 is an interface display diagram illustrating a focusing method according to an example embodiment of the present disclosure. Fig. 3 is a flowchart illustrating a focusing method according to an example embodiment of the present disclosure. As shown in fig. 2-3, the focusing method provided in this embodiment includes:
Specifically, when a user takes a picture, the camera is triggered to acquire a preview image, where it is understood that the preview image is an image acquired by the electronic device, and specifically may be an image acquired by using the camera before taking a picture, that is, an image displayed in the electronic device, for example, a display screen, after the user opens the mobile phone camera but before triggering the taking a picture.
After the preview image is acquired, whether a preset target image exists in the preview image is judged. It should be noted that, in this embodiment, the specific type of the preset target image is not limited, and the preset target image only needs to be set to satisfy that the target image can be recognized from the preview image and the focusing operation can be performed on the corresponding region.
In addition, the preset target image can be acquired by the user through a camera for storage, or can be transmitted and input by the user through an external device.
If the preview image has the preset target image, further determining a region of the preset target image in the preview image, for example, a region of the preset face image in the preview image or a region of the preset object image in the preview image. After the area of the preset target image in the preview image is determined, the area is selected as a focusing area to carry out focusing operation.
Referring to fig. 2, if the preview image has a preset face image, the area of the preset face image 101 in the preview image is further determined as a focusing area 110 for focusing. The other face images 102 are taken as the background, so that the preset face image 101 has the best shooting effect.
And 204, focusing according to a preset focusing strategy.
However, if the preview image does not have the preset target image, the user may focus manually, or focus according to a preset focusing strategy. For example: the focusing area is determined according to the area of the face area or the position of the face area or the area of the article area. It should be noted that, in this embodiment, the preset focusing strategy adopted for the case that the preset target image does not exist in the preview image may be any focusing strategy, which is not specifically limited in this embodiment, and even when the preset target image does not exist in the preview image, the auto-focusing operation may not be performed.
In the embodiment, the preview image is obtained, the area of the preset target image in the preview image is determined, and then the determined area is used as the focusing area for focusing to realize focusing of the specific target object, so that the specific target has a better shooting effect in the shot image, and the personalized shooting requirements of the user are met.
Fig. 4 is a flowchart illustrating a focusing method according to another example embodiment of the present disclosure. As shown in fig. 4, the focusing method provided in this embodiment includes:
Specifically, when a user uses a mobile phone to take a picture of a plurality of people, the camera is triggered to acquire a preview image, wherein the preview image comprises a plurality of face images.
And 302, matching each human face in the preview image with a preset human face image.
After the preview image with a plurality of face images is obtained, matching each face image in the preview image with a preset face image, wherein the matching process can be a face recognition process, and is not repeated here.
The preset face image may be an authentication face image stored in the electronic device, such as an authentication face image collected when a mobile phone owner performs face ID unlocking. Therefore, the authentication face image used for unlocking the mobile phone is directly determined as the preset face image used for focusing and identifying, and the trouble caused by collecting the face image for multiple times for the user is further avoided.
And step 303, judging whether the matching is successful. If yes, go to step 304, otherwise go to step 305.
If a preset face image exists in the preview image, for example, the face image of the owner, after each face image in the preview image is matched with the preset face image, focusing can be performed on the area where the preset face image is located.
And step 304, determining the area of the preset face image in the preview image as a focusing area for focusing.
When one of the face images in the preview image can be successfully matched with the preset face image, determining the area of the preset face image in the preview image as a focusing area for focusing.
And 305, judging whether a plurality of face images exist in the preview image. If yes, go to step 306, otherwise go to step 307.
However, when there is no face image that can be successfully matched with the preset face image in the preview image, there may be only one face image because there may be a plurality of face images in the preview image. Therefore, whether a plurality of face images exist in the preview image or only one face image exists can be determined, and then different focusing strategies are adopted.
And step 306, determining the area where the face image with the largest image area or the face image with the middle position is located as a focusing area for focusing.
If the preview image does not have the preset face image and the preview image has a plurality of face images, determining the area of the face image with the largest image area or the face image with the middle position as the focusing area for focusing.
However, if the difference of each face in the preview image is within a certain range, it can be determined as a group photograph, and the focusing operation is not performed.
And 307, determining the only face image in the preview image as a focusing area for focusing.
And if the preview image does not have the preset face image and only one face image exists in the preview image, determining the only face image in the preview image as a focusing area for focusing.
In addition, in order to further improve the shooting effect of the main face, after a preset face image is determined in the preview image, and focusing is performed, photometry is performed on a focused area to obtain photometry data, and then image processing is performed on the face image in the focused area according to the photometry data, for example: and (5) performing beautifying treatment.
If a plurality of face authentication images exist in one mobile phone, that is, both couples and partners can unlock the same mobile phone by using faces, and since a common girl prefers beauty than a boy, before focusing, the priority order of each authentication face image needs to be determined, wherein the preset face image comprises a plurality of authentication face images, when a plurality of authentication face images exist in the preview image, for example, a main face image of the male and a main face image of the female exist at the same time, one authentication face image serving as a determined focusing area can be determined according to the priority order, so that focusing is preferentially performed on the main face image of the female, and subsequent beauty operation can be preferentially performed.
