In the embodiment of the invention, a first preview image displayed on a first screen is acquired; under the condition that the first preview image comprises a target shooting object with preset characteristics, outputting first prompt information, wherein the first prompt information is used for prompting adjustment of a shooting view field, automatically reminding a user that the view angle is insufficient in the shooting process, and enabling the user to move the folding screen to shoot the image according to the prompt, so that the effects of complete close-shot portrait and saturated image are achieved.
Referring to fig. 2, a second flowchart of a prompting method provided in the embodiment of the present invention is shown.
The prompting method provided by the embodiment of the invention comprises the following steps:
step 201: a first preview image displayed on a first screen is acquired.
The embodiment of the invention is applied to the mobile terminal with the first screen and the second screen.
In the shooting preview interface, a first preview screen in a first screen is identified. Whether an incomplete target photographic object exists at the edge of the first preview picture or whether an overlapped target photographic object exists in the first preview picture is detected.
Step 202: and under the condition that the first preview image comprises the target shooting object with the preset characteristics, outputting first prompt information.
The first prompt information is used for prompting the adjustment of the shooting view field. Wherein the preset features include: an incomplete target photographic object or at least two overlapped target photographic objects exist in a preset area of the first preview image.
As shown in fig. 3, when it is detected that an incomplete target photographic subject or at least two overlapped target photographic subjects exist in the preset area, a first prompt message "please move the target screen" is output, where in fig. 3, 01 denotes the incomplete target photographic subject, and 02 denotes the at least two overlapped target photographic subjects.
When the complete target shooting object exists at the edge of the first preview picture or the target shooting objects in the first preview picture are overlapped, the prompt information for adjusting the shooting view field is output, and the user adjusts the view angle according to the prompt information, so that the complete image or the overlapped target shooting objects in the first preview picture can be displayed separately.
Step 203: and receiving bending input of the target screen by a user.
Wherein the bending input is used to trigger a change in a folding angle between the first screen and the second screen.
The user can fold the second screen, so that the second screen can acquire a complete target photographic object or non-overlapping target photographic objects in the first preview picture. When the target screen is bent and input, a second preview image acquired by the camera of the second screen can be displayed on the second screen, and the second screen can be used for inputting the target screen only by calling the camera of the second screen without displaying the preview image.
Except for the fact that incomplete portrait exists at the edge of the first preview picture or overlapped portrait exists in the first preview picture, prompt information for prompting adjustment of the shooting view field is output, when the first screen and the second screen simultaneously display the preview pictures, when the fact that the portrait overlapping area is too much or the fact that incomplete portrait exists at the edge of the screen is detected, the prompt information for prompting adjustment of the shooting view field is output, and a user folds the first screen or the second screen according to the prompt information.
Step 204: and responding to the bending input, and acquiring a second preview image acquired by a camera of the second screen.
And when the target screen is folded, calling a camera of the second screen to obtain second preview pictures with different visual angles.
Step 205: a first image of a target photographic object in the first preview image is acquired.
And acquiring a first image corresponding to an incomplete target shooting object or an overlapped target shooting object from the first preview image.
Step 206: and acquiring a second image of the target shooting object in the second preview image.
And acquiring a second image corresponding to the complete target shooting object or the non-overlapped target shooting object from the second preview image.
Step 207: and carrying out image synthesis on the first image and the second image to generate a third image of the target shooting object.
When an incomplete portrait exists at the edge of the first preview picture, the background algorithm completes the incomplete portrait according to the first image and the second image to obtain a third image, specifically, the third image can be generated by stitching the first image and the second image, and the first image and the second image are firstly subjected to image registration, wherein the image registration method mainly comprises an image registration algorithm based on phase correlation, geometric region and characteristics. The image registration algorithm based on phase correlation firstly carries out Fourier transformation on an input image sequence, and then calculates the relative displacement between images by using the phase information in a cross power spectrum after the image transformation so as to carry out image registration. The image registration algorithm based on the geometric region correlation is used for performing image registration by performing correlation operation on partial geometric subregions of an input image on the gray level of image pixel points. The image splicing algorithm based on the features firstly extracts the features of the images to be spliced, then completes image registration through feature matching, and splices the registered images to generate a third image.
When the first preview picture has the folded portrait and the folding degree of the folded portrait is greater than the preset degree, the background algorithm automatically splits the overlapped portrait according to the first image and the second image to obtain a third image, and specifically, the third image can also be generated by splicing the first image and the second image. When the number of the second images is multiple, the first image and each second image are subjected to image registration, the overlapped target shooting objects in the first image are registered in each second target image, and the registered target shooting objects in each second image are spliced to generate a third image, so that a better portrait co-shooting effect is achieved.
Specifically, the image is algorithmically transformed from the image shown in fig. 3 into the image shown in fig. 4, that is, the incomplete target photographic object does not exist in the third image, wherein 03 represents the complete target photographic object after the incomplete target photographic object of fig. 3 is processed.
As shown in fig. 5, when preview images are displayed on the first screen and the second screen, and an incomplete target photographic subject and at least two overlapped target photographic subjects coexist in the preview images, a third image of the target photographic subject is generated by a specific algorithm, wherein 04 represents the incomplete target photographic subject, and 05 represents the at least two overlapped target photographic subjects, and as shown in fig. 6, the overlapped portraits are respectively displayed separately in a separated manner, and the incomplete portraits are displayed completely.
When the target shooting image with the preset characteristics exists in the first preview image, in addition to outputting prompt information for adjusting the shooting field of view, under the condition that the target shooting object with the preset characteristics is included in the first preview image, second prompt information can be output, and the second prompt information is used for prompting the target shooting object to adjust the shooting position.
When the camera of the second screen cannot split and display the target shooting object, prompt information for prompting the target shooting object to adjust the shooting position is output, saturation of the picture is enhanced, and the shooting object is not shielded.
And when the user does not need to add a new portrait in the current third image, performing edge locking operation on the edge of the third image.
The method specifically comprises the following steps: receiving a first input of a user to the third image; determining a target boundary based on a target object selected by a first input; the display of the first preview image and/or the second preview image is updated based on the target boundary.
Note that the first input may be an upward slide operation or a downward slide operation on the third image. And when the locking is not needed, accepting a second input of the third image by the user. The second input is opposite to the first input, and when the first input is an upward sliding operation, the second input is a downward sliding operation, and when the first input is a downward sliding operation, the second input is an upward sliding operation, and the first input and the second input are not limited to the above, and may be other sliding operations, for example: the embodiment of the present invention does not specifically limit the operations, such as a double-click operation, a single-machine operation, a long-press operation, and a preset trajectory sliding operation, on the edge of the third image.
Through the first input of the third image, the problem that the non-shooting object is randomly input into the picture to interfere the shooting effect can be avoided.
The user can also shoot the third image and receive shooting input of the third image; shooting a preset number of target images according to shooting input; wherein, the shooting angle of each target image is different, and each target image is output and displayed.
As shown in fig. 7, a preset number of image output displays are generated.
And when the user shoots the third image, receiving shooting input by the user, and shooting according to the shooting input.
It should be noted that, a person skilled in the art may set the preset number according to actual situations, which may be 3, 5, 7, and the like, and the embodiment of the present invention is not limited in this respect.
In the embodiment of the invention, a first preview image displayed on a first screen is acquired; under the condition that the first preview image comprises a target shooting object with preset characteristics, outputting first prompt information, wherein the first prompt information is used for prompting adjustment of a shooting view field, automatically reminding a user that the view angle is insufficient in the shooting process, and enabling the user to move the folding screen to shoot the image according to the prompt, so that the effects of complete close-shot portrait and saturated image are achieved. In addition, when unnecessary human images are not needed to enter the preview picture, the third image can be subjected to the first input, namely the third image is subjected to target image locking, and the shooting effect is enhanced.
