In yet another exemplary embodiment, the terminal device may be a millet handset, the terminal device being provided with two cameras, one being a wide angle camera and the other being a tele camera. The original image is a video frame in the video. When the terminal equipment records the video, the wide-angle camera and the long-focus camera are called at the same time to record the video normally, the aperture values of the wide-angle camera and the long-focus camera are both 4, the zooming capability of the long-focus camera is called immediately, and the video is recorded by quickly drawing Jiao Duan. In the process of recording video by pulling in the focal length, the aperture value of the tele camera can be changed. For example, one of the frames may have an aperture value of 8. In the present exemplary embodiment, the terminal device acquiring the photographing information of the photographed photograph may include: the number information of cameras, the type information of cameras, the device information of photographing devices, and aperture values.

In one embodiment, before step S301, the method may further include: when a photographing instruction is received, at least two original images are photographed based on different photographing information. And after step S303, may further include: storing at least two target images carrying target watermarks; the target watermarks carried by the at least two target images are different. For example, in the continuous shooting mode, after the terminal device receives a shooting instruction, if shooting information changes during shooting, the terminal device may shoot at least two original images based on different shooting information. Then, the terminal device can obtain corresponding target watermarks according to respective shooting information of at least two original images to obtain at least two target watermarks. Then, the terminal device may add at least two target watermarks to the corresponding original images, resulting in at least two target images carrying the target watermarks. Because the shooting information of each of the at least two original images is different, the target watermarks carried by the at least two target images are also different. Thus, the user can conveniently recognize the shooting information of the current image through the watermark, and the use value of the watermark can be improved. It should be noted that, the image processing method in the continuous shooting mode is similar to the image processing method in the video recording process, and will not be illustrated here.
In the embodiment of the disclosure, the target watermark carried by the target image includes at least one of shooting parameters, scene mode information and camera working state information, so that the target image can show that the original image in the target image can be shot under what shooting conditions, and the use value of the watermark, the flow property and the transmissibility of the image are improved. Moreover, the hardware capability of the mobile phone can be better and more exposed and highlighted in the image circulation process.
In the embodiment of the disclosure, because the shooting information of the shot original image can be obtained, and the target watermark is obtained according to the shooting information and the corresponding relation between the shooting information and the watermark, the shooting information of the original image is carried in the target watermark. The shooting information comprises at least one of shooting parameters, scene mode information and camera working state information, so that the target watermark carries at least one of the shooting parameters, the scene mode information and the camera working state information. In this way, the target watermark is added to the original image, and the obtained target image carrying the target watermark carries at least one of shooting parameters, scene mode information and camera working state information. Therefore, according to the technical scheme of the embodiment of the disclosure, different watermarks can be correspondingly generated according to different shooting information, so that a user can identify the shooting information of the current image through the watermarks, the use value of the watermarks can be improved, and the fluxion and the transmissibility of the images carrying the watermarks can be improved.
Fig. 8 is a flowchart illustrating an image processing method according to another exemplary embodiment. In this embodiment, the original image may include a foreground image and a background image. The layer where the background image is located below the layer where the foreground image is located. For example, when the terminal device shoots a person image in a portrait blurring mode, the shot original image includes a foreground image and a background image, the foreground image is a clear person image, the background image is a blurred background image, and a layer where the background image is located below a layer where the foreground image is located. On the basis of the embodiment shown in fig. 1, after the above step S301, the following steps S801 to S803 may be further included:
in step S801, a blurring process is performed on a background image in the target image, so as to obtain a blurred background image.
In one embodiment, the terminal device may provide a function of adjusting the degree of blurring of the background image in the target image. After obtaining the target image carrying the target watermark, the terminal device can perform blurring processing on the background image in the target image according to the received control instruction for adjusting the blurring strength of the background image, so as to obtain a blurring background image.
In step S802, the blurring strength of the blurring-post-blurring background image is determined.
In one exemplary embodiment, the image may be divided into 100 blur levels from sharp to gaussian blur, each blur level corresponding to one blurring strength value. For example, when the image is clear, the blurring level 1 corresponds to a blurring strength value of 1, when the image is gaussian-blurred, the blurring level 100 corresponds to a blurring strength value of 100, and the blurring strength value of 100 corresponds to a blurring strength value of 1. The corresponding relation between the blurring level and blurring strength can be stored in the terminal device.
In the above-described exemplary embodiment, the terminal device may first determine the blur level of the blurred background image, and then obtain the blurring strength of the background image according to the blur level of the background image and the correspondence between the blur level and the blurring strength.
In step S803, the target watermark is updated according to the blurring strength.
In one embodiment, the blurring strengths of the background images are different, as are the corresponding target watermarks. Thus, when the blurring strength of the background image is updated, the target watermark described above is also updated.
In one embodiment, the photographing information includes photographing parameters including an aperture value; the target watermark carries an aperture value for shooting the background image. As shown in fig. 9, a target watermark 91 may be carried on the target image. The aperture icon 911 in the target watermark 91 indicates that the aperture value of the shot background image is 4, the "MI PHONE" in the text SHOT ON MI PHONE MI DUAL CAMERA912 indicates a millet PHONE, and the "DUAL CAMERA" indicates that the terminal device has two CAMERAs. As shown in fig. 10, step S803 may include the following steps S1001 to S1003:
in step S1001, a target aperture value is obtained according to the blurring strength and the correspondence relationship between blurring strength and aperture value.
In one embodiment, the correspondence between the blurring strength and the aperture value is stored in the terminal device in advance. For example, the aperture values 2 to 22 are divided into 100 levels, each level corresponding to one blurring intensity value. For example, the blurring intensity value corresponding to the aperture value 2 is 1, the blurring intensity value corresponding to the aperture value 2.2 is 2, the blurring intensity value corresponding to the aperture value 2.4 is 3, … …, the blurring intensity value corresponding to the aperture value 21.8 is 99, and the blurring intensity value corresponding to the aperture value 22 is 100. The terminal device may obtain the target aperture value according to the determined blurring strength of the background image and a correspondence between the blurring strength and the aperture value.
In step S1002, a new target watermark is obtained according to the target aperture value and the correspondence between the aperture value and the watermark.
In one embodiment, the correspondence between the aperture value and the watermark is pre-stored in the terminal device. The terminal device may obtain a new target watermark according to the target aperture value and the corresponding relation between the aperture value and the watermark. For example, when the target aperture value of the post-blurring-background image obtained after blurring processing is 8, a new target watermark 92 as shown in fig. 11 may be obtained according to the correspondence relationship of the aperture value and the watermark. Wherein the aperture icon 921 in the target watermark 92 indicates that the aperture value of the photographed background image is 8.
In step S1003, the target watermark is updated to the new target watermark.
In one embodiment, after obtaining the new target watermark, the terminal device may update the target watermark before the blurring process to the new target watermark.
In this embodiment, when editing the blurring degree of the photo later in the album, the user can see that the aperture of the watermark changes in opening and closing along with the change of the blurring strength value, which is a visual feedback of the shooting software capability.
In this embodiment, in the process of adjusting the blurring strength of the background image in the target image, the target watermark may be updated according to the blurring strength of the background image, which provides a feedback manner of the visible photographing software capability.
