Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a shooting focal length adjusting method and terminal equipment.

Background

With the wider application range of the terminal device, the user can trigger the terminal device to focus in an automatic focusing or manual focusing manner.

Taking a manual focusing manner as an example, at present, a user may input a manual focusing control in a shooting interface of a terminal device to trigger the terminal device to focus on a shot object. For example, taking a manual focusing control as a focusing progress bar as an example, the user may slide on the focusing progress bar to trigger the terminal device to adjust the shooting focal length.

However, since the length of the focusing progress bar in the above-described photographing interface is limited, in the case where the step size (the distance between two scales on the focusing progress bar) is fixed, the number of scales on the focusing progress bar is limited, resulting in low photographing focusing accuracy.

The operating system may be an Android (Android) operating system, an ios operating system, or other possible operating systems, and embodiments of the present invention are not limited in particular.

Next, a software environment applied to the method for adjusting a shooting focal length according to the embodiment of the present invention is described by taking an android operating system as an example.

Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).

The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.

The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.

The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system.

The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.

Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the shooting focal length adjustment method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the shooting focal length adjustment method may operate based on the android operating system shown in fig. 1. Namely, the processor or the terminal device can realize the shooting focal length adjusting method provided by the embodiment of the invention by running the software program in the android operating system.

The terminal equipment in the embodiment of the invention can be a mobile terminal or a non-mobile terminal. For example, the mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a palm top computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile terminal may be a Personal Computer (PC), a Television (TV), a teller machine or a self-service machine, and the like, and the embodiment of the present invention is not particularly limited.

The execution subject of the shooting focal length adjustment method provided in the embodiment of the present invention may be the terminal device, or may also be a functional module and/or a functional entity capable of implementing the shooting focal length adjustment method in the terminal device, and may specifically be determined according to actual use requirements, which is not limited in the embodiment of the present invention. The following takes a terminal device as an example to exemplarily explain the shooting focal length adjustment method provided by the embodiment of the present invention.

As shown in fig. 2, an embodiment of the present invention provides a shooting focus adjustment method, where the shooting focus adjustment method is applied to a folding screen type terminal device, where the terminal device may include a first screen and a second screen, and the shooting focus adjustment method may include steps 200 to 201 described below.

Step 200, the terminal device receives a first input of a user to the first screen in the shooting process.

In the embodiment of the invention, if a user needs to use the terminal device for shooting, the user can trigger the terminal device to run the camera application program at the moment, and under the condition that the terminal device runs the camera application program and the second screen displays the shooting preview interface, the user can trigger the terminal device to execute the action of shooting focusing through inputting to the first screen, namely, the shooting focal length is adjusted.

Optionally, in the embodiment of the present invention, when the terminal device runs the camera application, if the current mode is a Manual Focus (MF) mode, the terminal device may respond to the target input of the user and execute a shooting focusing action. For example, the user may select an MF mode (e.g., MF in the "professional" item shown in fig. 3) in which the user may trigger the terminal device to perform an action of photographing focus through the above-described target input.

Optionally, in the embodiment of the present invention, when the terminal device runs the camera application, if the current mode is the full-automatic mode (that is, all the parameters are set by the system algorithm), the terminal device may not respond to the target input of the user. For example, in the case of the full-automatic mode, even if the user folds the screen of the terminal device, the terminal device does not perform an action of photographing focus.

Step 201, the terminal device responds to the first input, and adjusts the shooting focal length of the target image displayed in the shooting preview interface in the second screen to a target focal length value associated with the first input.

Optionally, in an embodiment of the present invention, the first input may be a bending input to the first screen, or an input to two focusing controls displayed on the first screen. The following describes in detail a specific implementation manner of the shooting focus adjustment method provided by the embodiment of the present invention under different first inputs through a first implementation manner and a second implementation manner.

First embodiment

In the first embodiment, the first input is a bending input to the first screen.

Referring to fig. 2, as shown in fig. 3, the step 200 may be specifically realized by a step 200a described below, and the step 201 may be specifically realized by a step 201a described below.

Step 200a, the terminal device receives a bending input of the first screen by a user.

The bending input is used for triggering and adjusting the folding angle between the first screen and the second screen to a first angle.

In the embodiment of the present invention, when the second screen is used for displaying a shooting preview interface, the first input to the first screen by the user may be a bending input that changes a folding angle between the first screen and the second screen by folding the first screen. It may be understood that, the above exemplary description has been given by taking the first input as the user's bending input on the first screen, and the embodiment of the present invention is not limited thereto, and if the first screen is used for displaying the shooting preview interface, the first input may be a user's bending input on the second screen. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

In this embodiment of the present invention, if the user folds the first screen of the terminal device, so that the folding angle between the first screen and the second screen is changed, the terminal device may detect the folding angle between the first screen and the second screen (i.e., the first angle) in response to the input.

Optionally, in the embodiment of the present invention, the terminal device may use a gyroscope (angular motion sensing device) to detect the folding angle between the first screen and the second screen, and may also use any other possible angle sensor to detect the folding angle between the first screen and the second screen, which may be determined specifically according to actual use requirements, and the embodiment of the present invention is not limited.

Step 201a, the terminal device responds to the bending input, and adjusts the shooting focal length of the target image displayed in the shooting preview interface in the second screen to a target focal length value associated with the first angle.

In the embodiment of the present invention, the terminal device may detect a folding angle (i.e., a first angle) between the first screen and the second screen in response to the bending input, determine a focal length value (i.e., a target focal length value) corresponding to the folding angle, and adjust a shooting focal length of a target image displayed in the shooting preview interface in the second screen to the target focal length value.

In the embodiment of the invention, the terminal device can pre-store the corresponding relation between the folding angle between the first screen and the second screen and the focal length value, wherein one folding angle corresponds to one focal length value. Illustratively, as shown in table 1, when the folding angle between the first screen and the second screen is 90 °, the focal length value is 0.1 m; when the folding angle between the first screen and the second screen is 120 degrees, the focal length value is 5 meters; when the folding angle between the first screen and the second screen is 180 °, the focal length value is infinite.

Folding angle	Focal length value
		90°	0.1 m
150°	5 m
		180°	+∞

TABLE 1

In this embodiment of the present invention, the terminal device may determine, according to the correspondence, a focal length value (i.e., the target focal length value) corresponding to the folding angle (i.e., the first angle) according to the folding angle between the first screen and the second screen.

It is understood that the above-mentioned correspondence between the folding angle and the focal length value is an exemplary list, that is, the embodiments of the present invention include, but are not limited to, the above-mentioned listed correspondence and the number of the correspondence. In practice, the above correspondence may also be any other possible correspondence, for example, when the folding angle between the first screen and the second screen is 120 °, the focal length value may be 5 meters. Also, the number of the correspondence relationships may be determined according to the detection accuracy of the folding angle. Specifically, the corresponding content and the number of the corresponding relationship may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

Optionally, in an embodiment of the present invention, a folding angle between the first screen and the second screen may be within a first target value range, the focal length value may be within a second target value range, a minimum value of the second target value range may correspond to a minimum value of the first target value range (i.e., the minimum focal length value corresponds to the minimum folding angle), and a maximum value of the second target value range may correspond to a maximum value of the first target value range (i.e., the maximum focal length value corresponds to the maximum folding angle), where the minimum value of the second target value range is the minimum shooting focal length, and the maximum value of the second target value range is the maximum shooting focal length. The minimum value of the first target numerical range is the same as the minimum shooting focal length, and the maximum value of the first target numerical range is the same as the maximum shooting focal length.

Illustratively, assuming that the minimum photographing focal length is 0.1 m and the maximum photographing focal length is + ∞, i.e., the photographing focal length may be in the range of [0.1 m, + ∞), and the folding angle between the first screen and the second screen may be in the range of [90 °, 180 ° ], then the folding angle of 90 ° corresponds to a focal length value of 0.1 m, and the folding angle of 180 ° corresponds to a focal length value + ∞.

It is to be understood that the above focal length ranges are exemplary lists, i.e., embodiments of the present invention include, but are not limited to, the above listed focal length values. In practice, the above focal distance range may be any other possible value range, for example, the shooting focal distance may be in the range of [15 cm, + ∞). Specifically, the numerical values of the minimum shooting focal length and the maximum shooting focal length may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

It will also be appreciated that the ranges of fold angles between the first and second panels described above are also exemplary lists, i.e., embodiments of the present invention include, but are not limited to, the above listed fold angles. In practice, the range of the folding angle may be any other possible value range, for example, the folding angle may be in the range of [100 °, 170 ° ]. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

It should be noted that, the above description is an exemplary description taking the minimum folding angle corresponding to the minimum focal length value and the maximum folding angle corresponding to the maximum focal length value as examples, and it is understood that the embodiments of the present invention are not limited thereto, and may also include the following cases: the minimum focal length value corresponds to the maximum folding angle, and the maximum focal length value corresponds to the minimum folding angle, which may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

In the embodiment of the present invention, the focal length value corresponding to the folding angle may be determined according to the corresponding relationship between the folding angle between the first screen and the second screen and the focal length value, and according to the folding angle between the first screen and the second screen. Because the detection precision of the angle value is higher, the focus value is determined through the angle value, and the focusing precision can be improved.

Optionally, in an embodiment of the present invention, the first target range may include M first values (M is an integer greater than 1), the second target range may include M second values, and the M first values and the M second values are in one-to-one correspondence.

In an embodiment of the present invention, a difference between any two adjacent values of the M first values is the same (i.e., the M first values may form an equal difference sequence). For example, assuming that the folding angle between the first screen and the second screen is in the range of [90 °, 180 ° ] and the detection accuracy of the folding angle is 1 °, the first target value range may include 90 (i.e., M) first values, and the difference between any two adjacent values of the 90 first values may be 1 °.

Optionally, in a possible implementation manner, the difference between any two adjacent values in the M second values is the same (that is, the M second values may form an equal difference sequence). For example, assuming that the shooting focal distance may be in the range of [0.1 meter, + ∞) and the second target numerical range includes 90 second numerical values, the difference between any two adjacent ones of the 90 second numerical values may be approximately 0.1 meter each.

It should be noted that, in the foregoing embodiment, the difference between any two adjacent values in the M second values is taken as an exemplary illustration, and it is understood that the embodiment of the present invention is not limited thereto, and the M second values may also follow other number sequence rules, and may be determined according to actual use requirements, and the embodiment of the present invention is not limited thereto.

Alternatively, in another possible implementation manner, the M second values may include first K second values and second T second values ((where M is K + T, and the K second values are all smaller than the T second values), and a difference between any two adjacent values of the first K second values is smaller than a difference between any two adjacent values of the second T second values (that is, a step size of the first K second values is smaller than a step size of the second T second values), a difference between any two adjacent values of the first K second values is the same, and a difference between any two adjacent values of the second T second values is the same.

It should be noted that, in the foregoing embodiment, the difference between any two adjacent values of the K second values is the same, and the difference between any two adjacent values of the T second values is the same as an exemplary description, it is understood that the embodiment of the present invention is not limited thereto, and the following cases may also be included: the difference value between any two adjacent values in the first K second values is the same, and the last T second values can be arranged according to other sequence rules; or the first K second values may be regularly arranged according to other number sequences, and the difference between any two adjacent values in the last T second values is the same, which may be determined specifically according to the actual use requirement, and the embodiment of the present invention is not limited.

It should be noted that, in the foregoing embodiment, the M second values including the first K second values and the last T second values are used as an exemplary description, and it is understood that the embodiment of the present invention is not limited to this, and may also include any other possible cases, for example, the M second values may include the first L second values, the middle P second values, and the last S second values (where M is L + P + S), which may be determined according to actual usage requirements, and the embodiment of the present invention is not limited.

In the embodiment of the invention, after the terminal device determines the target folding angle between the first screen and the second screen and determines the target focal length value corresponding to the target folding angle, the shooting focal length can be adjusted to the target focal length value.

In the embodiment of the present invention, the correspondence between the folding angle and the focal length value between the first screen and the second screen is not limited to the above correspondence, and may be determined specifically according to actual use requirements. Because the detection precision of the angle value is higher, the focus value is determined through the angle value according to the corresponding relation between the angle value and the focus value, and the focusing precision can be improved.

A specific implementation of the shooting focus adjustment method provided by the embodiment of the present invention is exemplarily described below with reference to fig. 4, 5, and 6. First, as shown in fig. 4, 5 and 6, it is assumed that the terminal device includes a first screen 30 and a second screen 31, and in the case where the terminal device runs a camera application, the second screen 31 may display a shooting preview interface, and it is assumed that a tree 32 displayed in the shooting preview interface is far away from the terminal device (for example, the distance between the two is far greater than 5 meters, which is understood as infinity), a car 33 is 5 meters away from the terminal device, and a flower 34 is 0.1 meter away from the terminal device. In the MF mode, the user may fold or rotate the first screen 30 with respect to the second screen 31 (i.e., the above-described object input) such that the folding angle between the first screen 30 and the second screen 31 varies within a range of [90 °, 180 ° ] to trigger the terminal device to perform an action of photographing focusing.

As shown in fig. 4, when the terminal device detects that the target folding angle between the first screen 30 and the second screen 31 is 180 °, the terminal device may determine that the target focal distance value from the target folding angle 180 ° is + ∞withreference to the correspondence of table 1, and then the terminal device adjusts the photographing focal distance to the target value + ∞, that is, the focusing position is infinity, so that a tree 32 that is infinity from the terminal device is clear, and a car 33 that is 5 meters away from the terminal device and a flower 34 that is 0.1 meters away from the terminal device are blurred.

As shown in fig. 5, when the terminal device detects that the target folding angle between the first screen 30 and the second screen 31 is 150 °, the terminal device may determine that the target focal length value is 5 meters from the target folding angle of 150 ° with reference to the correspondence of table 1, and then the terminal device adjusts the photographing focal length to the target value of 5 meters, that is, the focusing position is 5 meters, so that a car 33 5 meters away from the terminal device is clear, and a tree 32 infinity from the terminal device and a flower 34 0.1 meter away from the terminal device are blurred.

As shown in fig. 6, when the terminal device detects that the target folding angle between the first screen 30 and the second screen 31 is 90 °, the terminal device may determine that the target focal distance value is 0.1 m from the target folding angle of 90 ° with reference to the correspondence of table 1, and then the terminal device adjusts the photographing focal distance to the target value of 0.1 m, that is, the focusing position is 0.1 m, so that a flower 34 that is 0.1 m from the terminal device is clear, and a tree 32 that is infinity from the terminal device and a car 33 that is 5 m from the terminal device are blurred.

As can be clearly understood from the above-described exemplary descriptions in conjunction with fig. 4, 5, and 6, the terminal device can control the photographing focus position to be adjusted within the range of [0.1 m, + ∞) during the change of the folding angle between the first screen and the second screen within the range of [90 °, 180 ° ].

In the above-described embodiment of the present invention, assuming that the detection accuracy (i.e., the step size) of the folding angle is 1 °, if the folding angle between the first screen and the second screen is in the range of [90 °, 180 ° ], the number of folding angles that can be detected by the terminal device is 90. Since each folding angle corresponds to one focal length value, 90 folding angles can correspond to 90 focal length values (corresponding to 90 scales). Assuming that the photographing focal distance is in the range of [0.1 m, + ∞), the terminal device can adjust the photographing focal distance between 90 focal distance values in the range of [0.1 m, + ∞).

Assuming that the photographing focal length is in the range of [0.1 m, + ∞) in the related art, since the number of scales on the focusing progress bar in the photographing interface is limited (e.g., 25), the terminal device can adjust the photographing focal length between 30 focal length values in the range of [0.1 m, + ∞), thereby making the focusing accuracy low. Compared with the prior art, the number of available focal length values in the same focal length range can be increased in the embodiment of the invention, so that the focusing precision of the terminal equipment can be obviously improved.

In addition, different from the action of triggering the terminal device to execute shooting focusing by sliding the focusing progress bar in the prior art, the embodiment of the invention triggers the terminal device to execute the shooting focusing action by folding the screen of the folding screen type terminal device, so that the interestingness of using the terminal device by a user can be increased.

According to the shooting focal length adjusting method provided by the embodiment of the invention, the shooting focal length of the terminal equipment can be adjusted to the target focal length value corresponding to the folding angle between the two screens, so that the focal length value can depend on the size of the folding angle, namely, the focusing accuracy can depend on the detection accuracy of the folding angle.

Second embodiment

In a second embodiment, the first input is input to two focus controls displayed on the first screen.

Referring to fig. 2, as shown in fig. 7, the step 200 may be implemented by the steps 200b to 200e described below, and the step 201 may be implemented by the step 201b described below.

Step 200b, the terminal device receives a first sub-input of a user to a first focus control in a first area of a first screen.

Wherein the first region corresponds to a first range of values.

In the embodiment of the present invention, the control for controlling the shooting focus in the terminal device may include a first focus control and a second focus control, where the first focus control is used to control the shooting focus to be adjusted within the overall focus range (i.e., for coarse adjustment), and the second focus control is used to control the shooting focus to be adjusted within the local focus range (i.e., for fine adjustment or fine adjustment).

If the user needs to use the terminal device to shoot, at this time, the user may trigger the terminal device to run the camera application, and in the case that the terminal device runs the camera application and the current mode is the MF mode, the user may trigger the terminal device to perform an action of shooting focusing, that is, adjusting a shooting focal length within the overall focal length range (i.e., coarse adjustment), by a first input to the first focus control in the first area.

In the embodiment of the present invention, the terminal device may separately lay out the first focus control and the first region corresponding to the first numerical range, and accordingly, the user may slide on the first focus control to trigger the terminal device to control focusing within the first numerical range. Or, the terminal device may lay out the first focus control and the first numerical range as a first focus progress bar, display the first numerical range on the first focus progress bar, and the user may slide on the first focus progress bar to trigger the terminal device to control focusing within the first numerical range. The layout form of the first focus control and the first region may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

And 200c, the terminal equipment responds to the first sub-input and updates the position of the first focus control in the first area.
