Example one
Referring to fig. 1, a flowchart illustrating steps of a photographing method provided in an embodiment of the present invention is shown, where the photographing method may be applied to an electronic device, and specifically includes the following steps:
step 101: and acquiring an image to be superposed.
In the embodiment of the present invention, the electronic Device may be a mobile electronic Device such as a mobile phone and a PAD (Portable Android Device).
The camera refers to a camera device preset on the electronic device, and may be a front camera of the electronic device or a rear camera of the electronic device, and specifically may be determined according to actual conditions.
The image to be superimposed is an image for superimposing the image to the preview image to obtain a final fused image, that is, the user needs to acquire the image superimposed on the preview image from other images, and the image to be superimposed and the preview image are mutually fused to obtain the fused image.
In the invention, the image to be superimposed can be an image selected by a user from a plurality of images locally pre-stored in the electronic equipment, and a person or an object and the like needing to be superimposed in a shooting area are extracted from the selected image; or some images automatically provided by the electronic device for the user in the process of acquiring the preview image of the shooting area by the user may be provided, specifically, the method may be determined according to business requirements, and the embodiment of the present invention is not limited thereto.
After the image to be superimposed is acquired, step 102 is performed.
Step 102: and superposing the image to be superposed to a preview interface, wherein the preview interface displays a preview image.
The preview interface is an interface for collecting preview images displayed on a screen of the electronic equipment when the electronic equipment is in a shooting mode.
The preview image is an image displayed in a preview interface in the process of performing image acquisition, preview focusing and the like on a photographic subject before the photographic subject is photographed.
When the preview image is collected, the preview image can be collected by using a front camera of the electronic equipment, namely, the preview image is collected by using a camera positioned on one side of a display screen of the electronic equipment. Of course, a back camera of the electronic device may also be used to acquire the preview image, that is, the camera located on the opposite side of the display screen of the electronic device is used to acquire the preview image, which may be determined according to practical situations, and the embodiment of the present invention is not limited to this.
After the image to be superimposed is acquired, the image to be superimposed may be superimposed on a preview interface, that is, a preview interface of the electronic device on which the image to be superimposed is to be superimposed, and further, in a subsequent process, brightness, position, size, and the like of the image to be superimposed may be adjusted, for example, referring to fig. 2d, a schematic diagram of image segmentation provided in the embodiment of the present invention is shown, in fig. 2d, after the original image is superimposed on the preview interface, an image a and an image B may be segmented from the original image, and the image a and the image B may be taken as the image to be superimposed.

The image depth determines the number of colors each pixel of a color image may have, or the number of gray levels each pixel of a gray scale image may have, which determines the maximum number of colors that may appear in a color image, or the maximum gray level in a gray scale image, e.g., a single color image, if each pixel has 8 bits, the maximum gray level is the 8 th power of 2, i.e., 256.
The second characteristic information refers to characteristic information of the image to be superimposed, and the second characteristic information may be image display parameter information of the image to be superimposed, such as one or more of parameters of brightness, saturation, color and the like; the second feature information may also be image depth information of the image to be superimposed.
After the preview image is acquired, first feature information of the preview image, such as parameters of ISO (Sensitivity), aperture size, and the like, may be acquired according to the currently focused parameter.
The second feature information of the image to be superimposed may be obtained according to the original image obtained from the image to be superimposed, and specifically, will be described in detail in the following embodiments.
After extracting the first feature information from the preview image and extracting the second feature information from the image to be superimposed, the image to be superimposed and/or the photographing parameter may be adjusted according to the first feature information and the second feature information, and specifically, when the first feature information and the second feature information are both image display parameter information, the photographing parameter (such as a brightness parameter, a saturation parameter, a color parameter, and the like) of the image to be superimposed may be adjusted according to display parameter information such as a brightness parameter, a saturation parameter, a color parameter, and the like of the preview image, so that the image display parameter of the image to be superimposed matches with the image display parameter of the preview image, and the image effect of the subsequently generated fusion image is improved.
When the first characteristic information and the second characteristic information are both image depth information, the size and the position of the image to be superposed can be adjusted according to the image depth information of the preview image and the image depth information of the image to be superposed, so that the fusion effect of the two images is better.
