Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.
The existing electronic equipment is generally provided with a group of cameras, namely a plurality of lenses, so that the increasingly rich shooting requirements of people are met.
There is typically a telephoto lens among the multiple cameras of the electronic device so that the user can take a farther picture. Telephoto lenses, such as periscopic zoom lenses, in combination with digital zoom, can achieve zoom magnifications of up to 50 times.
In general, a main lens used by default by an electronic apparatus configured with multiple cameras is not a telephoto lens, and therefore the following occurs: when the default main shooting lens is used for previewing, the target to be shot is already at the center of the screen, but after the zoom lens is switched to the telephoto lens with high magnification, the target to be shot is not displayed in the previewed screen after the zoom lens is switched. The main reasons are hand trembling of the user and registration problems between the two cameras during the handover. When this occurs, the user needs to move the electronic apparatus with high magnification to move the object to be photographed, which the user originally desires to photograph, into the preview screen. However, in the case of high magnification, a small movement of the electronic device is reflected on the screen and is a huge movement, which causes a secondary composition under the telephoto lens (i.e., selecting the object to be photographed again) to be troublesome. Therefore, when a main shooting lens previewing picture is shot by using a telephoto lens at present, a common shooting method is to enlarge the picture step by step, namely, a user enlarges the picture a little by a little and ensures that the target to be shot is kept in the current previewing picture. In summary, the existing shooting methods have been unable to meet the increasing shooting requirements of users.
Referring to fig. 1, fig. 1 is a schematic flow chart of a shooting method according to an embodiment of the present invention, where the method is applied to an electronic device, and includes:
step 11: receiving a first input of a user;
step 12: selecting a target photographing region in a first preview screen in response to the first input;
step 13: receiving a first operation of a user;
step 14: changing a display position of the target photographing region in the first preview screen in response to the first operation;
step 15: and when the target shooting area is displayed in the target display area, displaying a second preview picture, wherein the second preview picture displays the amplified target shooting area. Thus, the user can finish shooting at a high magnification based on the second preview screen.
In the embodiment of the invention, a user can select the target shooting area by using low magnification, then the electronic equipment automatically identifies whether the target shooting area is displayed in the target display area, and if the target shooting area is displayed in the target display area, the target shooting area is automatically switched to the second preview picture, and the amplified target shooting area is displayed in the second preview picture, so that the user does not need to adjust the magnification many times to select the target shooting area, the operation is simple and convenient, the shooting time can be greatly shortened, and the shooting experience of the user is improved.
The above-described photographing method is exemplified below.
Optionally, the first input may be a sliding input on a screen, and a line connecting starting points of the sliding input is a diagonal line of the target shooting area. The first input may also be a click input, and a position of the click is a central point of the target photographing region. The first operation may specifically be an operation of moving the electronic device.
Optionally, before the step of receiving the first input of the user, the method further includes:
receiving a second input;
in response to the second input, a target shooting mode is initiated that assists in selecting a target shooting region, also referred to as assisting in high magnification composition.
Specifically, referring to fig. 2, after starting the shooting function of the electronic device, the user enters a preview interface, a first preview screen is displayed, then the user selects a target shooting mode, and finally, referring to fig. 3, the user defines a target shooting area 1 on the first preview screen.
Optionally, after the target photographing region is selected in the first preview screen, the method further includes:
and displaying guide information according to the relative position relation between the target shooting area and the target display area.
The guiding information is used for guiding a user to move the electronic equipment until the target shooting area is displayed in the target display area.
Specifically, in the embodiment of the present invention, after the user selects the target shooting area in the first preview screen (specifically, the wide-angle preview screen), the electronic device guides the user to move the electronic device to a corresponding position by displaying the guidance information, so that the target shooting area (specifically, the corresponding object to be shot) is displayed in the target display area. Therefore, when the shooting is switched to the high-magnification shooting, the object to be shot corresponding to the target shooting area can be displayed in the switched preview picture, and the problem that a user needs to repeatedly move the electronic equipment to move the object to be shot into the picture after the switching is avoided. In addition, the magnification can be directly adjusted to the target magnification capable of magnifying the target shooting area to the whole preview picture without progressive magnification, so that the shooting time can be greatly shortened, and the shooting experience of a user is improved.
Optionally, referring to fig. 4, the display guidance information may specifically be a display guidance arrow 2 and/or a calibration frame 3 of the target display area, where a direction of the arrow is consistent with a direction in which the electronic device needs to move.
In addition, the target display area may be determined according to the target photographing area, for example, the size of the target display area may coincide with the size of the target photographing area.
Optionally, the electronic device includes a first lens and a second lens, the first preview screen is captured by the first lens, and the second preview screen is captured by the second lens. The first lens may be a main camera lens of the electronic device, and is generally a wide-angle lens. The second lens may be a telephoto lens. And the magnification of the second lens when the second preview picture is collected is larger than that of the first lens when the first preview picture is collected.
That is, the embodiment of the present invention provides a method for shooting a target shooting area (specifically, shooting an object to be shot displayed in the target shooting area) in a preview picture of another lens (that is, a first lens) by using a lens (that is, a second lens) with a high magnification, and when an electronic device is switched from a first lens to a second lens with a high magnification, it can be ensured that the object to be shot displayed in a preview picture (a first preview picture) corresponding to the first lens can be displayed in the preview picture (a second preview picture) after the preview picture is switched to the second lens.
In the embodiment of the invention, the electronic equipment comprises a plurality of lenses, and the first preview image and the second preview image are acquired by different lenses respectively. The shooting capability of the electronic equipment can be greatly enhanced by arranging a plurality of lenses.
It should be noted that, when determining the target display area, the target display area needs to be determined by combining the calibration information of the first lens and the second lens.
Optionally, before displaying the second preview screen when the target shooting area is displayed in the target display area, the method further includes:
and determining the magnification of the target shooting area according to the size of the target shooting area in the first preview picture and the size of the display screen of the electronic equipment.
In the embodiment of the present invention, the length-width ratio of the target shooting area is consistent with the length-width ratio of the display screen of the electronic device, that is, the length-width ratio of the preview image. Specifically, a size ratio of the display screen of the electronic device to the target shooting area may be acquired as a magnification of the target shooting area. For example, the magnification of the target photographing region may be calculated according to the following formula:
Ratio_all＝Ori_width/Roi_width
wherein Ratio _ all is a total magnification, that is, a magnification of the target shooting area; ori _ width is the width of a display screen of the electronic equipment; and Roi _ width is the display width of the target shooting area. Of course, the magnification of the target shooting area can also be obtained by calculating the ratio of the length (height) of the display screen of the electronic device to the length (height) of the display of the target shooting area.
In another optional embodiment, the magnification of the target capturing area may be obtained according to a ratio of an area of a display screen of the electronic device to an area of the target capturing area in the first preview screen.
In the embodiment of the present invention, the magnification of the target shooting area is a relative magnification, that is, the magnification of the second preview screen is relative to the magnification of the first preview screen, and if the magnification of the first preview screen is greater than 1, the absolute magnification of the target shooting area is the magnification of the target shooting area multiplied by the magnification of the first preview screen.
Optionally, acquiring the magnification of the second lens when the second preview screen is displayed as a target lens magnification;
the second lens has at least one first magnification, the first magnification is smaller than or equal to the magnification of the target shooting area (which may also be referred to as a target magnification), and the target lens magnification is the largest first magnification among the at least one first magnification.
In the embodiment of the present invention, the target magnification ratio is not necessarily equal to the target magnification ratio, that is, the target magnification ratio is not necessarily achieved by zooming the second lens, and digital zooming may be combined. For example, if the magnification of the second lens is only 2 times, 3 times and 5 times selectable, and the target magnification is 4 times, the target lens magnification is determined to be 3 times, and the remainder is filled in by the digital zoom. If the magnification of the second lens is only 2 times, 3 times and 5 times selectable, and the target magnification is 5 times, the target lens magnification is determined to be 5 times without being magnified through digital zooming. If the magnification of the second lens is only 2 times, 3 times and 5 times selectable, and the target magnification is 8 times, the target lens magnification is determined to be 5 times, and the rest is filled up through digital zooming. The magnification of the digital zoom can be calculated by the following formula:
Ratio_digit＝Ratio_all/Ratio_lens
wherein Ratio _ digit is the magnification of the digital zoom, Ratio _ all is the target magnification, and Ratio _ lens is the target lens magnification. That is, the target magnification is equal to the magnification of the digital zoom multiplied by the target lens magnification.
In addition, when the electronic device includes a first lens and a second lens, the first preview image is captured by the first lens, the second preview image is captured by the second lens, and the second lens has at least one first magnification, if the default magnification when the second lens is started is not the target lens magnification, the magnification of the second lens is directly switched from the default magnification to the target lens magnification.
In the embodiment of the invention, the magnification of the second lens can be directly adjusted to the magnification of the target lens without amplifying step by step, so that the shooting time can be greatly shortened, and the shooting experience of a user can be improved. In addition, while switching the second lens, if the target magnification includes a magnification of the digital zoom, the digital zoom of a corresponding magnification is also required.
Optionally, the method further includes:
and when the target shooting area is displayed in the target display area, displaying first indication information.
Therefore, the user can judge whether to stop moving the electronic equipment according to the guide information and can stop moving the electronic equipment in time according to the displayed first indication information.
Optionally, the method further includes:
in a first operation process of receiving a user, namely in a moving process of the electronic device, displaying second indication information, wherein the second indication information is used for indicating a current display position of the target shooting area (specifically, a corresponding object to be shot).
Specifically, the object to be photographed in the target photographing region is tracked by calculating orb (organized FAST and Rotated bright) features of a preview screen. The second indication information may be a frame that moves with the movement of the display position of the object to be photographed.
In the embodiment of the invention, the second indication information for indicating the current display position of the object to be shot corresponding to the target shooting area is displayed, so that a user can visually see the real-time display position of the object to be shot in the process of moving the electronic equipment.
In addition, if the second indication information is a box, it may be indicated whether the target photographing region is displayed in the target display region by a change in box color, that is, the box color of the second indication information may be used as the first indication information. Specifically, when the object to be photographed is not displayed in the target display area, the color of the square frame is green, and once the object to be photographed is displayed in the target display area, the color of the square frame is switched to red.
Further optionally, when the target shooting area is displayed in the target display area, displaying a second preview screen specifically includes:
and displaying the second preview picture when the target shooting area is displayed in the target display area and the continuous display duration meets a preset condition.
Wherein, the continuous display duration may be used as the first indication information. Specifically, when it is detected that the target shooting area is displayed in the target display area, the display of timing information is started, and the timer is counting up or counting down.
In another optional embodiment of the present invention, when the target shooting area is displayed in the target display area, the displaying a second preview screen specifically includes:
when N continuous frames of target preview pictures are detected, switching to the second preview picture;
the target preview picture is a first preview picture in which an object to be shot corresponding to the target shooting area is displayed in the target display area.
For example, when it is detected that the target display area contains the object to be photographed on the first preview screen of 5 continuous frames, the second preview screen is automatically switched to. Specifically, a lens is switched from a first lens to a second lens, the magnification of the second lens is the target lens magnification, and if the target magnification includes the digital zoom magnification, the digital zoom with the corresponding magnification is also required.
In the embodiment of the invention, on the detected continuous multi-frame first preview picture, if the target display area contains the object to be shot, the second preview picture is automatically switched to. Therefore, the switching speed is high, the situation that the object to be shot deviates from the target display area after being displayed in the target display area due to hand trembling of a user can be prevented, the object to be shot corresponding to the target shooting area can be further ensured to be displayed in the switched preview picture when the shooting is switched to the high magnification ratio, and the problem that the user needs to repeatedly move the electronic equipment to move the object to be shot into the picture after the switching is avoided.
According to the embodiment of the invention, the target shooting area defined by the user in the first preview picture can be enlarged to the whole preview picture. Specifically, please refer to fig. 5, the object to be photographed corresponding to the target photographing region is enlarged to the whole preview screen, so that the user does not need to perform the recomposition on in the second preview screen, that is, does not need to reselect the object to be photographed in the second preview screen.
Of course, since the display size of the target photographing region is small when the user demarcates the target photographing region in the first preview screen, the composition may not be accurate. Therefore, after switching to the second preview screen, if the user is not satisfied with the composition, the user can perform fine adjustment by moving the electronic device, and click to shoot after the fine adjustment is completed.
