Technical Field

Background

With the rapid development of the zoom technology, the zoom capability of the electronic device is greatly improved, and the zoom function (i.e., the function of adjusting the zoom factor) also becomes a hot topic. When the user uses the electronic equipment to take a picture, the utilization rate of the zooming function is gradually improved. Therefore, how to zoom is very important to the user's shooting experience.

At present, a user adjusts a zoom factor through a gesture of two fingers, wherein the zoom factor is increased when the distance between the two fingers is increased, so that the content of a designated area is enlarged; when the two fingers are folded, the zooming times are reduced, so that the content of the designated area is reduced. When the zoom factor is adjusted in this way, generally, a user holds the electronic device with one hand and operates two fingers of the other hand to adjust the zoom factor. In this case, it is difficult to use both hands of the user.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 shows a flow chart of a zoom factor adjusting method according to an embodiment of the present invention. The zoom factor adjusting method is applied to the electronic device, and as shown in fig. 1, the zoom factor adjusting method includes:

step 101, the electronic device receives a first input of a user to a shooting preview interface, wherein the first input is an input of a first finger of the user.

The first finger may be one finger of the user, and the first input may be a single-click input or a multi-continuous-click input.

Step 102, the electronic device responds to the first input, and obtains an input parameter of the first input.

Optionally, the input parameters of the first input include, but are not limited to, input strength, single input duration, input times, input speed, and input interval duration, wherein the input interval duration is a time interval between two consecutive inputs. For example, the first input is a click input, and the input parameter is click strength or click duration. For another example, the first input is a double-click input, and the input parameter is an input strength or an input speed. For another example, the first input is a three-click input, and the input parameter is a click speed or an average duration between two adjacent clicks.

And 103, the electronic equipment adjusts the zoom multiple according to the first target adjustment mode and the first target adjustment amplitude associated with the input parameter of the first input.

Alternatively, the user may preset a first target adjustment amplitude associated with the input parameter of the first input, or the electronic device may default to set the first target adjustment amplitude associated with the input parameter of the first input.

For example, referring to fig. 2, the electronic device displays a shooting preview interface, where the zoom factor is 1 zoom. One finger 001 of the user double-clicks the shooting preview interface. The electronic equipment receives double-click input of the finger 001 of the user, and responds to the double-click input to acquire the strength of the double-click input. Since the first target adjustment range associated with the strength of the double-click input is 1-time zoom adjustment range, the first target adjustment manner is a manner of increasing the zoom multiple. Thus, the electronic device increases the zoom factor from 1-fold zoom to 2-fold zoom.

Optionally, in one or more embodiments of the present invention, after acquiring the input parameters of the first input, and before adjusting the zoom multiple according to the first target adjustment manner and the first target adjustment amplitude associated with the input parameters of the first input, the zoom multiple adjustment method further includes:

the electronic equipment determines a first target adjusting amplitude according to the incidence relation between the input parameters and the adjusting amplitude of the zooming multiple.

Wherein, the correlation between the input parameter and the adjusting amplitude of the zoom multiple can be established in advance. The association may be a one-to-one correspondence between a plurality of values of the input parameter and a plurality of adjustment magnitudes of the zoom multiple. For example, the adjustment amplitude associated with the user click strength of 1 is 1 zoom adjustment amplitude; the adjustment amplitude associated with the user click strength of 2 is 3 times the adjustment amplitude of the zoom. For another example, the adjustment range associated with the user input speed of 1 time/second is 1 zoom adjustment range; the user inputs an adjustment amplitude associated with a speed of 2 times per second of 2 times zoom.

Alternatively, the correlation may be a functional relationship between the input parameter and the adjustment magnitude of the zoom factor. Such as a relationship where the functional relationship is a linear function or a relationship of other functions. For example, the association is a function:

y＝a×x+b (1)

y denotes the adjustment amplitude of the zoom factor, x denotes input parameters, and a and b denote predetermined coefficients, which may be default or set by the user.

In the embodiment of the invention, according to the correlation between the input parameter and the adjustment amplitude of the zoom multiple, a first target adjustment amplitude of the zoom multiple can be determined. Therefore, the zoom multiple can be adjusted by one-hand operation of a user.

Optionally, in one or more embodiments of the present invention, before determining the first target adjustment amplitude according to the correlation between the input parameter and the adjustment amplitude of the zoom multiple, the zoom multiple adjustment method further includes:

and the electronic equipment acquires the incidence relation corresponding to the target shooting object according to the target shooting object in the shooting preview interface.

The user can preset different association relations corresponding to different target shooting objects. Or, the electronic device defaults to set different association relations corresponding to different target shooting objects.

For example, when the target object is a person, the relationship of association corresponding to the person is as the following formula (1):

y＝a1×x+b1 (2)

where y denotes an adjustment amplitude of the zoom factor, x denotes an input parameter, and a1 and b1 are predetermined coefficients, respectively. The a1 and b1 may be coefficients of a system default of the electronic device or coefficients preset by a user.

In the case where the target photographic subject is a subject, the association relationship corresponding to the subject is as in the following formula (2):

y＝a2×x+b2 (3)

where y denotes an adjustment width of the zoom factor, x denotes a value of the input parameter, and a2 and b2 are predetermined coefficients, respectively. The a2 and b2 may be coefficients of a system default of the electronic device or coefficients preset by a user.

In the embodiment of the invention, when shooting is carried out aiming at different target shooting objects, although the input parameters of the user are the same, the first target adjusting amplitude of the zoom multiple is different. For example, when the user shoots a person, the click strength of the user is 1, and the first target adjustment range is 1 zoom adjustment range. Under the condition that a user shoots a scene, the clicking strength of the user is 1, and the first target adjustment amplitude is 2 times of the zoom adjustment amplitude. Therefore, the embodiment of the invention meets the requirement of realizing accurate adjustment of the zoom multiple under different shooting scenes.

Optionally, in one or more embodiments of the present invention, the first target adjustment amplitude obtained according to the association relationship corresponding to the person is smaller than the first target adjustment amplitude obtained according to the association relationship corresponding to the scene.

Since the proportion of the face area in the shooting preview interface to the total area of the shooting preview interface in the character shooting scene is greater than the first predetermined threshold, for example, the first predetermined threshold is 80%. Or the number of faces in the shooting preview interface is greater than a predetermined number, such as 3. In this case, the user generally needs to fine-tune the face size, which may cause the portrait to go out of frame if the adjustment range of the zoom factor is too large. Therefore, the incidence relation corresponding to the figure is obtained to adjust the zooming multiple, the situation that the face is out of the frame due to overlarge adjusting range of the zooming multiple is avoided, and the situation that the user repeatedly adjusts the zooming multiple is avoided.

In a scene shooting scene, since too high zoom precision is not required, it is sufficient to ensure the approximate position of the scene in the image. Therefore, the zoom multiple is adjusted according to the incidence relation corresponding to the scenery, and the zoom is quickly realized in the scenery shooting scene.

For example, in the above formula (2) and formula (3), b2 in formula (3) is equal to b1 in formula (2), and a2 in formula (3) is greater than a1 in formula (2). Thus, in the case where x is the same, the zoom factor calculated by the formula (3) is larger than the zoom factor calculated by the formula (2). Therefore, in the case of photographing a person, the zoom factor can be adjusted by equation (2), thereby achieving fine adjustment of the zoom factor. In the case of photographing a scene, the zoom factor can be adjusted by formula (3), thereby rapidly achieving zooming in the scene of the scene photographing.

Optionally, before step 101, the zoom factor adjusting method further includes:

the electronic equipment receives input of a user on a first preset acquisition interface and input of a user on a second preset acquisition interface respectively; the first preset acquisition interface is an interface for acquiring the maximum value of the input parameters, and the second preset acquisition interface is an interface for acquiring the minimum value of the input parameters. The first preset acquisition interface and the second preset acquisition interface may be the same interface or different interfaces.

The electronic equipment responds to the input of the first preset acquisition interface, and takes the input parameters input to the first preset acquisition area as the maximum value of the input parameters; responding to the input of the second preset acquisition area, and taking the input parameter input to the second preset acquisition interface as the minimum value of the input parameter;

the electronic device may generate the association relationship according to the maximum value of the input parameter and the first adjustment amplitude associated therewith, and the minimum value of the input parameter and the second adjustment amplitude associated therewith.

For example, the input parameter is a force. The electronic device receives user input to the settings control and, in response to the input, displays an interface 002 as shown in fig. 3. On the interface 002, the acquisition region 003 corresponding to the double click and the acquisition region 004 corresponding to the double click are displayed.

In the case of the interface 002 shown in fig. 3, the electronic apparatus receives an input of the user's finger 001 for double-clicking the corresponding acquisition region 003, and in response to the input, displays a first preset acquisition interface as shown in fig. 4. The electronic equipment receives click input of a user finger 004 on a first preset acquisition interface; and responding to the click input, and taking the click input strength value as the input strength maximum value, so as to realize the acquisition of the input strength maximum value.

In the case of interface 002 as shown in fig. 3, the electronic device receives an input of a finger 001 of the user for lightly double-clicking a corresponding acquisition region 004, and in response to the input, a second preset acquisition interface is displayed. Since the input force minimum is collected in a similar manner to the input force maximum, and how to collect the input force maximum has been described above. Therefore, the minimum value of the input strength is not repeated here.

After the minimum value and the maximum value of the input force are collected, due to default setting of the electronic equipment or preset by a user: the first adjusting amplitude corresponding to the maximum value of the input force is 4 times of the adjusting amplitude of zooming, and the second adjusting amplitude corresponding to the minimum value of the input force is 1 time of the adjusting amplitude of zooming. Therefore, the association relationship can be generated according to the maximum value of the input force and the corresponding adjustment range of the zoom of 4 times, and the minimum value of the input force and the corresponding adjustment range of the zoom of 1 time. For example, the generated correlation is a functional relationship shown in the above formula (1). Generating the functional relationship includes: coefficients a and b in equation (1) are determined. Thereby, the above formula (1) is obtained.

Optionally, in one or more embodiments of the present invention, before step 101, or after step 103, the zoom factor adjusting method further includes:

the electronic equipment receives second input of a user to a first control in a shooting preview interface, wherein the first control is a control for indicating adjustment of zoom times;

and the electronic equipment responds to the second input, and updates the zoom multiple according to a second target adjustment amplitude corresponding to the second input and a second target adjustment mode.

Wherein, the first control can be a progress bar indicating the adjustment of the zoom multiple. The second input may be at least one of the following inputs to the first control: slide input, click input, voice input, gesture input.

In the embodiment of the invention, the user can manually adjust the zoom multiple by using the first control, so that the requirement of the user for adjusting the zoom multiple through the control is met. For example, after the user adjusts the zoom factor through the first input, if the adjustment result of the zoom factor is not satisfactory, fine adjustment needs to be performed on the zoom factor. Therefore, fine adjustment of the zoom multiple can be achieved through the first control, and therefore the requirement that a user adjusts the zoom multiple more accurately is met.

Optionally, in one or more embodiments of the present invention, after updating the zoom multiple according to the second target adjustment amplitude corresponding to the second input and the second target adjustment manner, the zoom multiple adjustment method further includes:

the electronic equipment acquires a first numerical value of an input parameter and a first adjusting amplitude associated with the first numerical value; acquiring a second numerical value of the input parameter and a second adjusting amplitude associated with the second numerical value;

under the condition that the difference value between the first adjusting amplitude and the second target adjusting amplitude is smaller than the difference value between the second adjusting amplitude and the second target adjusting amplitude, the electronic equipment updates the first adjusting amplitude associated with the first numerical value to the second target adjusting amplitude and updates the association relation;

and under the condition that the difference value between the second adjusting amplitude and the second target adjusting amplitude is smaller than the difference value between the first adjusting amplitude and the second target adjusting amplitude, the electronic equipment updates the second adjusting amplitude associated with the second numerical value into the second target adjusting amplitude and updates the association relation.

For example, the first value is the input parameter maximum value, and the second value is the input parameter minimum value. The maximum value of the input force is 30 and the corresponding first adjusting amplitude is 4 times of the zooming adjusting amplitude, and the minimum value of the input force is 15 and the corresponding second adjusting amplitude is 1 time of the zooming adjusting amplitude, namely two points (30,4) (15,1), and a linear association relationship is generated according to the two points.

After that, the user adjusts the zoom magnification through the first control, and the adjustment amplitude is 2 times the adjustment amplitude of the zoom. For the adjustment range of 1 time zooming and the adjustment range of 4 times zooming in the two points (30,4) (15,1), the difference between the adjustment range of 2 times zooming and the adjustment range of 1 time zooming adjusted by the first control is smaller than the difference between the adjustment range of 2 times zooming and the adjustment range of 4 times zooming adjusted by the first control. Therefore, the adjustment range corresponding to the minimum value 15 of the input parameter is updated to 2 times zoom, that is, the two points are updated to (30,4) (15,2), so that a linear association relationship is generated according to the two updated points, and the association relationship is updated.

In the embodiment of the invention, the incidence relation is updated according to the habit of adjusting the zoom multiple of the user, so that the incidence relation is continuously suitable for the user, and the result of adjusting the zoom multiple by utilizing the incidence relation is more fit with the use habit of the user.

Optionally, in one or more embodiments of the present invention, before step 103, the zoom factor adjusting method further includes:

the electronic equipment determines the maximum zooming multiple or the minimum zooming multiple according to a target shooting object in the shooting preview interface.

For example, when the target object is a person, the minimum zoom magnification is 1-time zoom and the maximum zoom magnification is 6-time zoom. When the target shooting object is a scene, the minimum zoom multiple is 2 times zoom, and the maximum zoom multiple is 8 times zoom.

In the embodiment of the invention, the requirements for the zoom magnification are different due to different targets shooting the object. Therefore, the maximum zoom magnification or the minimum zoom magnification is determined for the target photographic subject. The situation that the zoom multiple is too large or too small can be avoided, and therefore an image with high quality is shot.

Optionally, in one or more embodiments of the present invention, the electronic device determines the maximum zoom magnification or the minimum zoom magnification according to the target photographic object in the photographic preview interface, including:

determining the minimum zoom multiple or the maximum zoom multiple according to the position of the character in the shooting preview interface under the condition that the target shooting object is the character;

when the target photographic object is a scene, the minimum zoom multiple or the maximum zoom multiple is determined according to the recommended photographic composition corresponding to the scene.

For example, the target shooting object is a person, and when the ratio of the area of the face in the shooting preview interface to the total area of the shooting preview interface is greater than a first predetermined threshold, or the number of faces in the shooting preview interface is greater than a predetermined number, where the predetermined number may be default or set by a user, the maximum zoom multiple is a zoom multiple corresponding to a guarantee face in the shooting preview interface, and the minimum zoom multiple is a zoom multiple corresponding to a guarantee face area as a preset first area, where the preset first area may be set by default or set by the user.

For another example, the target photographic subject is a scene, and a recommended photographic composition corresponding to the scene is acquired, the recommended photographic composition including at least one photographic subject. For example, the current shooting scene is a sea scene, and the recommended shooting composition includes the shooting objects of sea water and sand beach. The maximum zoom multiple is the zoom multiple corresponding to the condition that all the shooting objects in the recommended shooting composition appear in the shooting preview interface. The minimum zoom multiple is a zoom multiple which ensures that the area proportion is equal to that corresponding to a second predetermined threshold, and the area proportion is the proportion of the total area of the predetermined shooting objects in the recommended shooting composition in the area of the shooting preview interface, wherein the second predetermined threshold can be set by default or by a user.

Optionally, in one or more embodiments of the present invention, determining the maximum zoom magnification or the minimum zoom magnification according to the target photographic subject in the photographic preview interface includes:

the electronic equipment acquires a target image which is the same as the type of a target shooting object in a shooting preview interface;

the electronic equipment determines the maximum zooming multiple or the minimum zooming multiple according to the zooming multiple when the target image is shot.

For example, the target shooting object is a person, and the electronic device acquires three target images with the person which are shot in the album. The zoom factors when the three target images are shot are 2 times zoom, 3 times zoom and 6 times zoom respectively. Therefore, the minimum zoom factor may be 2 times zoom, and the maximum zoom factor may be 6 times zoom.

In the embodiment of the invention, the minimum zoom multiple or the maximum zoom multiple is determined according to the zoom habit of the user and the shot target shooting object. Therefore, the adjusted zoom multiple is within the range of the zoom multiple that the user is accustomed to, and the user is prevented from repeatedly adjusting the zoom multiple due to excessive zooming.

Optionally, in one or more embodiments of the present invention, in a case where the value before the zoom factor adjustment is greater than the minimum zoom factor and less than the maximum zoom factor, the first target adjustment manner is a manner of adjusting the zoom factor last time, and the manner of adjusting the zoom factor last time is increasing the zoom factor or decreasing the zoom factor;

in the case where the value before zoom factor adjustment is equal to the maximum zoom factor, the first target adjustment manner is to reduce the zoom factor;

in the case where the value before the zoom factor adjustment is equal to the minimum zoom factor, the first target adjustment manner is to increase the zoom factor.

For example, assume that the minimum zoom factor is 1 zoom and the maximum zoom factor is 8 zoom.

With continued reference to the interface diagram on the left side of fig. 2, the current zoom multiple is zoom by 1 time, the electronic device receives a double-click input of the finger 001 to the shooting preview interface, and the first target adjustment amplitude associated with the strength of the double-click input is the adjustment amplitude of zoom by 1 time. Thus, the electronic device increases the zoom factor from 1-fold zoom to 2-fold zoom. After that, if the electronic device continues to receive the double-click input of the user, the zoom magnification continues to be increased.

Referring to fig. 5, the current zoom factor is 8 times zoom, i.e. the maximum zoom factor is reached. In this case, the electronic device receives a double-click input of the user's finger 001 to the shooting preview interface, and the first target adjustment amplitude associated with the strength of the double-click input is an adjustment amplitude of 2 times zooming. Thus, the electronic device reduces the zoom factor from 8 times zoom to 6 times zoom.

In the embodiment of the invention, the zoom times are gradually increased; in the case of increasing to the maximum zoom factor, the zoom factor is gradually decreased. In the case of decreasing to the minimum zoom factor, the zoom factor is gradually decreased, and so on.

In the embodiment of the invention, a first input of a first finger of a user to a shooting preview interface is obtained, and an input parameter of the first input is obtained; and determining a first target adjusting amplitude according to the incidence relation between the input parameters and the adjusting amplitude of the zooming multiple so as to adjust the zooming multiple. Since the first finger of the user may be a single finger of the user, the user may adjust the zoom factor by the single finger. Under the condition, the user can adjust the zoom multiple by using the fingers of the hand holding the electronic equipment, so that the condition that one hand of the user is released by using two hands of the user during shooting is avoided, the convenience of adjusting the zoom multiple by the user is improved, the user can conveniently perform one-hand operation, and single-hand shooting can be performed. In addition, when shooting is carried out on different target shooting objects, although input parameters of users are the same, the first target adjusting amplitude of the zoom multiple is different, and therefore accurate adjustment of the zoom multiple under different shooting scenes is achieved. In addition, the incidence relation is updated according to the habit of the user for adjusting the zoom multiple, so that the incidence relation is continuously suitable for the user, and the result of adjusting the zoom multiple by utilizing the incidence relation is more fit with the use habit of the user. In addition, a minimum zoom multiple or a maximum zoom multiple is determined according to the zoom habit of the user and the target photographic subject to be photographed. Therefore, the adjusted zoom multiple is within the range of the zoom multiple that the user is accustomed to, and the user is prevented from repeatedly adjusting the zoom multiple due to excessive zooming.
