detailed description

The present application will be described in detail below with reference to the accompanying drawings and embodiments. Understandably, as described here The embodiments described are merely illustrative of the present application and are not intended to limit the application. It should also be noted that, for the convenience of description, only some, but not all, of the contents related to the present application are shown in the drawings.

Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as a process or method depicted as a flowchart. Although the flowcharts describe various operations (or steps) as a sequential process, many of the operations can be implemented in parallel, concurrently or concurrently. In addition, the order of operations can be rearranged. The process may be terminated when the operation is completed, but may not be included in the additional steps in the figures. The processing may correspond to methods, functions, procedures, subroutines, subroutines, and the like.

1 is a flowchart of a method for a first embodiment of a photographing method according to an embodiment of the present application. The method of the embodiment may be performed by a photographing device, and the device may be implemented by software and/or hardware, and Generally integrated in a mobile terminal.

In S110, an image acquired by the camera is identified, and it is determined whether a predetermined biometric exists in the image.

Watermark mode photography is a photo mode. For example, when taking a landscape photo, the user likes to attach a string of text watermarks to record mood and life. For example, when the user is taking a selfie, he likes to superimpose the cartoon watermark, such as superimposing the cat ear watermark on his head. However, the existing watermark mode photographing requires the user to adjust the size and angle of the cat's ear according to the size of the head in the image acquired by the camera and the angle of the pendulum to match the head of the image.

The photographing method provided by the embodiment of the present application firstly identifies an image acquired by the camera, and determines whether a predetermined biometric exists in the image, because when the photographing is performed, the angle and size of the watermark need to be adjusted to be related to the biometric feature in the image. Matching, for example, adding a beard watermark to the user's chin in the image, the beard watermark needs to be adjusted according to the position, size and angle of the user's chin, so it is necessary to first determine whether there is a biological feature about the chin in the image, and for the landscape class The image does not need to match the location of the watermark.

The predetermined biometrics can be a face, eyes, mouth, nose, arms, hair, and the like. Biometrics can select human biometrics as well as animal biometrics, which are not limited herein. Therefore, the size and angle of the watermark can be automatically adjusted according to the size and angle of the biometric features in the image. In the above example of adding a cat ear watermark, the user only needs to pose, and the cat ear watermark automatically matches the user's head according to the user's posture.

In S120, when a predetermined biometric is present in the image, the posture of the biometric is acquired The watermark gesture corresponding to the state, the watermark is superimposed to the image according to the watermark gesture.

Optionally, the watermark gesture includes a watermark location, a watermark size, and a watermark angle; the gesture of the biometric includes a biometric location, a biometric size, and a biometric angle.

The position of the biometric in the image acquired by the camera, the biometric size, and the biometric angle are stored in the terminal in the form of an array. If it is recognized that there is a predetermined biometric in the image, the relevant array data of the posture of the biometric is obtained. The relevant array data of the watermark position, the watermark size and the watermark angle are adjusted to match the relevant data of the biometric. Then, the watermark of the watermark gesture is superimposed on the image to obtain a picture that the user needs.

In summary, by identifying the image acquired by the camera, determining whether there is a predetermined biometric in the image, if there is a predetermined biometric in the image, acquiring the posture of the biometric, and acquiring the corresponding watermark according to the posture of the biometric Gesture, and superimpose the watermark on the image according to the watermark gesture. The technical solution automatically adjusts the watermark posture according to the posture of the biometric feature, and does not require the user to manually adjust the watermark posture, and the operation is simple, and the convenience of the photographing operation of the user is improved.

Please refer to FIG. 2 , which is a flowchart of a method for the second embodiment of the photographing method provided by the embodiment of the present application. On the basis of the first embodiment, the embodiment of the present application uses the system when determining whether a predetermined biometric exists. Matches the score threshold and increases the ability for the terminal to automatically take photos. In S210, an image acquired by the camera is identified.

When the image acquired by the camera is recognized, it is possible to first identify whether the image has obvious biometrics. For example, compared with the preset biometric face, it is obvious that the picture of the person's face can be judged, so that the face can be judged later.

In S220, it is determined whether there is a biometric that satisfies a system matching score threshold in the image. If there is no biometric that satisfies the system matching score threshold in the image, then S230 is performed, if the image exists in the image. If the biometric of the score threshold is matched, then S240 is performed.

Like the biometric gesture in the picture acquired by the camera, the data of the predetermined biometric is also preset in the terminal in the form of an array. For example, for the biometric mouth, the shape and color of the preset biometric mouth are at the terminal. The image is stored in the form of an array. When the matching of the array data of the acquired image with the preset array data of the biometric mouth exceeds a certain range, the modified part of the acquired image is considered to be a biometric mouth. The matching degree is determined by using a system matching score threshold. Illustratively, the system matching score threshold is 85 points, that is, the array data of a part of the acquired image and the array data of the preset biometrics exceed 85% similarity, you can confirm the camera There are predetermined biometrics in the image acquired by the head. A person skilled in the art can understand that the system matching score threshold value in the present application can be set by the system by default, and can be set by the user. This application is not limited.

In S230, a default watermark gesture is obtained, and the watermark is superimposed to the image according to the default watermark gesture.

If there is no biometric in the image that satisfies the system matching score threshold, then there is no biometric corresponding to the watermark in the image. The watermark is superimposed onto the image in a default watermark pose. The default watermark pose can be centered, unscaled, and not rotated.

In S240, a watermark gesture corresponding to the gesture of the biometric is acquired, and a watermark is superimposed to the image according to the watermark gesture.

If there is a biometric in the image that satisfies the system matching score threshold, then the biometric corresponding to the watermark exists in the image. The watermark is added to the position of the biometric feature in the image, and the watermark is scaled and rotated according to the size and angle of the biometric feature to obtain the watermarked image.

In S250, the image superimposed on the watermark is automatically photographed and saved.

After the terminal obtains the image after the watermark is added, the photographing operation is automatically performed, and the image after the watermark is superimposed is saved. The user does not need to manually click to take a photo, which avoids the problem that the biometrics and the watermark do not match due to the user's body shift when manually clicking on the photo. And the user only needs to select the watermark and the biometrics to get the watermarked image that he wants, which is simple and convenient.

In summary, by identifying the image acquired by the camera, it is determined whether there is a biometric in the image that satisfies the system matching score threshold. If there is a biometric that satisfies the system matching score threshold, the biometric gesture is acquired. And acquiring the corresponding watermark gesture according to the posture of the biometric feature, and superimposing the watermark on the image according to the watermark posture, thereby improving the convenience of the photographing operation of the user. At the same time, after the mobile terminal acquires the image after superimposing the watermark, the camera automatically performs the photographing, and the user does not need to manually click the photograph, thereby further improving the convenience of photographing.

Please refer to FIG. 3 , which is a flowchart of a method for the third embodiment of the photographing method provided by the embodiment of the present application. The second embodiment of the present application adds a preset step of watermark photographing. In S310, the photographing function of the watermark mode is turned on.

When the user needs to take a photo in the watermark mode, the photo function of the watermark mode is turned on, and the default watermark posture, the predetermined biometric type, and the system matching score threshold are selectively set. When the user does not need to take a photo in the watermark mode, the photo mode function of the watermark mode can be turned off.

In S320, a correspondence between the posture of the biometric and the watermark gesture is set.

After the photographing function of the watermark mode is turned on, the biometric type such as face, eyes, and mouth can be set, and the corresponding relationship between the gesture of the biometric feature and the watermark gesture can be set accordingly. The watermark may be a watermark library built in the terminal, or may be downloaded by a third party software to obtain a watermark library. Illustratively, the relative positional relationship between the biometric hair and the watermark in the crown, animal ears, hat, etc. in the watermark library is set, the crown is placed directly above the hair above the head, and the animal ears are placed on opposite sides of the hair on the head. When the user selects the watermark, the terminal can automatically add the selected watermark to the biometric related location.

In S330, the image acquired by the camera is identified, and the biometric feature that satisfies the system matching score threshold is determined in the image. If there is no biometric that satisfies the system matching score threshold in the image, then S340 is performed. If there is a biometric in the image that satisfies the system matching score threshold, then S350 is performed.

In S340, a default watermark gesture is obtained, and the watermark is superimposed to the image according to the default watermark gesture.

In S350, an instruction to select a biometric and a watermark by the user is received.

Before taking a photo, the user can select their own biometrics and corresponding watermarks. It is also possible to select only the watermark, and the watermark automatically matches the biometric. Since the correspondence between the pose of the biometric and the watermark pose is previously set, the watermark can be automatically matched to the biometric. For example, when the user selects a card sunglasses, the sunglasses automatically match the biometric eye.

In S360, the watermark gesture selected by the user corresponding to the biometric selected by the user is acquired.

Firstly, the posture of the biometric feature selected by the user is obtained, or the watermark is selected, and the watermark automatically corresponds to the biometric feature, the posture of the biometric feature in the image is obtained, and the posture of the watermark posture and the biometric feature are adjusted to match.

In S370, a watermark is superimposed to the image in accordance with the watermark gesture.

In S380, the image superimposed on the watermark is automatically photographed and saved.

In summary, after the user performs the photographing, after the photographing function of the watermark mode is turned on, the default watermark posture, the type of the predetermined biometric feature, and the system matching score threshold value need to be set. In addition, the posture of the biometric feature and the watermark posture can be set. Corresponding relationship, the user only needs to select the watermark that he wants to use, and the terminal is The entire photo taking process can be completed to improve the convenience of the photographing operation.

Please refer to FIG. 4 , which is a flowchart of a method for the fourth embodiment of the photographing method provided by the embodiment of the present application. The embodiment of the present application is an exemplary embodiment based on the third embodiment. In this embodiment, the user can add a watermark of the Halloween mask to the self-portrait image. In S410, it is detected that the user turns on the camera.

In S420, it is detected whether the photographing function of the watermark mode is turned on. If the photographing function of turning on the watermark mode is detected, S440 is performed, and if the photographing function of the watermarking mode is not detected, S430 is performed.

In S430, the setting is ended and the camera takes a picture in the normal mode.

In S440, a sub-option function of the watermark mode photographing is set, wherein the sub-options include a default watermark pose, a predetermined biometric type, and a system matching score threshold.

In the embodiment of the present application, the default watermark gesture is set to be centered, not scaled, and not rotated; the types of predetermined biometrics include face, eyes, nose, mouth, arms, and legs; and the system matching score threshold is set to 85 points. The record of this setting will be retained by the terminal until the user manually changes it next time. And set the correspondence between the gesture of the biometric and the watermark gesture. Illustratively, the watermark of the Halloween mask needs to be laid entirely on the user's face in the image and matched to the eyes, mouth, and the like.

In S450, it is detected that the user has selected the watermark of the Halloween mask.

In S460, according to the correspondence between the posture of the biometric and the watermark posture, detecting whether there is an obvious facial contour in the image acquired by the camera, and if it is detected that there is no obvious facial contour in the image acquired by the camera, executing S470, if When it is detected that there is a significant facial contour in the image acquired by the camera, S480 is performed.

In S470, the watermark is adjusted to the default watermark pose.

In S480, it is detected whether the matching degree between the facial contour in the image acquired by the camera and the biometric facial image pre-stored in the terminal exceeds a system matching score threshold, if the facial contour in the image acquired by the camera and the biometric pre-stored in the terminal If the matching degree of the face does not exceed the system matching score threshold, then S470 is performed. If the matching degree of the face contour in the image acquired by the camera and the biometric face pre-stored in the terminal exceeds the system matching score threshold, then S490 is performed.

In S490, according to the posture of the biometric face, the watermark gesture of the Halloween mask is adjusted to match the posture of the face.

For example, when the user is shooting, the squatting posture is taken, and when the face is tilted by 45 degrees, the terminal is controlled. The Halloween mask is also tilted 45 degrees to match the face.

In S4100, the image of the watermark superimposed on the Halloween mask is automatically photographed and saved.

In S4110, the preview state is restored, and execution returns to S450.

It is worth noting that the Halloween mask here is only an example, and other watermarks are equally applicable to this method. Therefore, in this example, after the image of the watermark superimposed on the Halloween mask is photographed and saved, the preview state is restored, and the user is again checked whether the watermark is selected. If the user selects the watermark, the steps of S450 to S4100 are performed for the watermark.

In summary, by identifying the image acquired by the camera, determining whether there is a biometric that satisfies the system matching score threshold in the image, and if there is a biometric in the image that satisfies the system matching score threshold, acquiring the biometric gesture, And according to the posture of the biometric feature, the corresponding watermark posture is acquired, and the watermark is superimposed on the image according to the watermark posture, and the photograph is automatically photographed and saved, thereby improving the convenience of the photographing operation of the user.
