In the embodiment of the present invention, the electronic device may be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, a Personal Digital Assistant (PDA), or the like.
In an embodiment of the present invention, an electronic device includes a retractable screen having an extended state and a retracted state, a portion of the screen being disposed inside the electronic device when the screen is in the retracted state; when the screen is switched to the stretching state, part of the screen arranged in the electronic equipment stretches out of the electronic equipment, and the whole display area of the screen is enlarged.
The expansion or contraction of the screen can be achieved by the prior art, for example: the structure and the specific telescopic manner of the screen having the extended state and the retracted state are not limited in the embodiment of the present invention, which is operated manually by a user or by a driving assembly provided in the electronic device.
Referring to fig. 1, an embodiment of the present invention provides a photographing method, where an execution subject of the method is an electronic device, the electronic device has a screen with an extendable length or width, and the method includes the following specific steps:
step 101: displaying a photographing preview interface in a screen;
in the embodiment of the invention, the photographing function is started on the electronic equipment so as to display the photographing preview interface in the screen. Optionally, the photographing function is turned on when the screen is in an initial state.
Referring to fig. 2a, a scene of the photo preview interface is displayed in the screen when the screen is in the initial state, wherein the target object 22 is included in the photo preview interface 21, and the display range of the photo preview interface 21 is much larger than the target object 22, so that an area which does not need to be photographed exists around the target object 22.
It should be noted that the screen shown in fig. 2a can be extended or contracted along the longitudinal direction, and for convenience of description, the direction parallel to the longitudinal direction of the screen is taken as the left and right direction, and the direction perpendicular to the longitudinal direction of the screen is taken as the up and down direction with respect to the orientation of the target object 22.
Step 102: receiving selection input of a user in a photographing preview interface;
in the embodiment of the present invention, the selection input is used to select a target picture from the photo preview interface, where the target picture corresponds to a target object that the user wants to photograph, and optionally, the selection input may be a sliding input in the photo preview interface, and the target picture is selected in the photo preview interface according to a track of the sliding input.
Referring to fig. 2b, the area marked out by the dashed line frame in the drawing is a target image, and corresponds to the target object 22, it can be understood that, in an actual application scene, the dashed line frame may be displayed in the photo preview interface 21, so that the user can know whether the target image selected by the user is correct, or the dashed line frame may not be displayed in the photo preview interface 21, so as to avoid a messy display content.
Step 103: adjusting the display range of the photographing preview interface by controlling the extension or contraction of the screen according to the display proportion of the target picture, and displaying the target picture in the adjusted photographing preview interface;
in the embodiment of the present invention, the display scale of the target frame refers to a scale of a display size of the target frame, for example, an aspect ratio of the target frame, and the display scale of the target frame selected by the user may not be consistent with the display scale of the current photo preview interface, for example: the display ratio of the current photo preview interface is 16:9, and the display ratio of the target picture may be 2:1, so that the display range of the photo preview interface needs to be adjusted. Specifically, the display range of the photographing preview interface is adjusted by extending or contracting the control screen.
In some embodiments, the focal length of the lens and the display area of the photo preview interface are adjusted by controlling the screen to extend or retract according to the display scale of the target picture.
The focal length of the lens is the distance from the optical rear principal point of the lens to the focal point, and is an important performance index of the lens, and the length of the focal length of the lens determines the size of the shot image. The focal length of a lens is changed by extending or contracting the screen, so that the size of a target object in the photographing preview interface is changed; the display area of the photographing preview interface refers to a preview photographing range displayed in the photographing preview interface under the condition of keeping the focal length of the lens unchanged. And controlling the screen to extend or contract, and changing the display area of the screen, thereby changing the display area of the picture taking preview interface in the screen.
It should be noted that increasing the focal length of the lens may increase the target object in the photo preview interface, which may cause the display range in one direction of the photo preview interface to satisfy the display of the target object, and the display range in the other directions to be insufficient to satisfy the display of the target object, for example: in the scene shown in fig. 2a, if the focal length of the lens is increased, when the display range in the width direction of the photo preview interface 21 can satisfy the display of the target object 22, the display range in the length direction may not satisfy the display of the target object 22, which may result in incomplete display of the target object.
In consideration of the problem of zooming of the target object in the process of adjusting the focal length of the lens, the focal length of the lens is increased under the condition that the screen is stretched, so that the display area of a photographing preview interface can be increased while the target object is enlarged, and the display of the target object is ensured to be met; correspondingly, under the condition that the screen is contracted, the focal length of the lens is reduced, and the display area of the photographing preview interface is synchronously reduced with the target object.
Referring to fig. 3, a scene of adjusting the focal length of the lens by extending or contracting the screen based on fig. 2a is shown, wherein the focal length of the lens is increased by extending the screen to increase the display range of the target object 22 in the photo preview interface 21, so as to remove the regions of the target object 22 that do not need to be photographed at the upper and lower sides. In this scenario, since the display area of the photo preview interface 21 is increased due to the stretching of the screen, regions that do not require photographing appear on the left and right sides of the target object 22, and therefore, further adjustment of the display area of the photo preview interface 21 is required.
Specifically, under the condition that the screen is stretched, the display area of the photographing preview interface is increased along the stretching direction of the screen; in the case of screen shrinkage, the display area of the photographing preview interface is reduced in the screen shrinkage direction.
Referring to fig. 4, a scene of adjusting the display area of the photo preview interface by screen expansion or contraction on the basis of fig. 3 is shown, wherein the display area of the photo preview interface is reduced in the screen contraction direction by screen contraction, so as to remove the regions of the target object 22 on the left and right sides that do not need to be photographed.
In some embodiments, the variation of the display area of the photo preview interface is matched with the variation of the screen, so that when the user controls the screen to stretch, the stretching amount of the screen is conveniently controlled, and the adjustment of the display area of the photo preview interface is more accurate.
Further, the focal length of the lens is locked under the condition that the display area of the photographing preview interface is adjusted through the expansion or contraction of the screen.
Therefore, when the display area of the photographing preview interface is adjusted, the focal length of the lens is unchanged, the display size of the target object is unchanged, and a user only needs to adjust the area of the photographing preview interface properly, so that the influence on the adjustment of the display area of the photographing preview interface due to the synchronous change of the display size of the target object is avoided.
The above-mentioned locking of the photographing focus multiple can be realized by performing touch input on a control in the screen, for example: referring to fig. 4, a lock control 23 is displayed in the photo preview interface 21, and the user can lock the focal length of the lens by clicking the lock control 23.
Step 104: and taking a picture based on the adjusted picture taking preview interface.
In the embodiment of the present invention, taking the scene shown in fig. 4 as an example, in the adjusted photo preview interface 21, the target object 22 substantially fills the whole photo preview interface 21, and the redundant regions that do not need to be photographed are all removed by adjustment.
In the embodiment of the invention, a user selects a target picture in the photographing preview interface, the display range of the photographing preview interface is adjusted by controlling the expansion or contraction of the screen of the electronic equipment according to the display proportion of the target picture, and photographing is carried out based on the adjusted photographing preview interface, so that the photographed picture meets the requirements of the user and does not need to be subjected to secondary processing.
