Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
Referring to fig. 1, a schematic diagram of an implementation environment provided by an exemplary embodiment of the present application is shown, where the implementation environment includes a terminal 110 and a shooting assistance device 120.
The terminal 110 is an electronic device with a shooting function, and may be a smart phone, a tablet computer, a digital player, and so on, and the terminal 110 is illustrated as a smart phone in fig. 1 as an example. Optionally, the terminal 110 is provided with a front camera assembly and a rear camera assembly, wherein the front camera assembly is located on one side of a terminal screen (generally used for self-shooting), and the rear camera assembly is located on one side of a terminal back cover.
In addition, the terminal 110 in the embodiment of the present application further has voice acquisition and voice recognition functions. Through the voice collection function, the terminal 110 may receive a voice control instruction of a user, and through the voice recognition function, the terminal 110 may recognize a control intention expressed by the voice control instruction. Optionally, the voice recognition function is implemented locally by the terminal 110, or implemented by the terminal 110 by using a server, which is not limited in this embodiment.
The shooting assistance device 120 is a device for assisting the terminal to shoot, and may be a selfie stick, a cradle head, a terminal support, and the like, and the shooting assistance device 120 is illustrated as a cradle head in fig. 1 as an example. When the terminal 110 is assisted by the shooting assistance device 120 to shoot, the terminal 110 and the shooting assistance device can be fixedly connected through a fixing component (such as a clamp, a suction cup, and the like) on the shooting assistance device 120.
In the embodiment of the present application, the auxiliary photographing device 120 further has a mechanical structure by which the auxiliary photographing device 120 can change the position or posture of the terminal 110, thereby changing the photographing effect of the terminal 110. For example, the photographing assistant device 120 is provided with a rotating mechanical structure by which the photographing assistant device can change a left and right photographing angle or a photographing pitch angle of the terminal; alternatively, the photographing assistant device 120 is provided with a guide mechanical structure by which the photographing assistant device can change a relative distance between the terminal and the photographing object. The embodiment of the present application does not limit the specific mechanical structure of the shooting assistance apparatus.
In order to achieve the mutual communication between the terminal 110 and the auxiliary shooting device 120, the terminal 110 and the auxiliary shooting device 120 establish a communication connection, which may be a wired communication connection or a wireless communication connection.
The wired communication connection may be a Universal Serial Bus (USB) connection; the Wireless Communication connection may be a bluetooth connection, a Wireless Fidelity (WiFi) connection, or an NFC (Near Field Communication) connection, which is not limited in this embodiment.
In the shooting scene, the terminal 110 and the shooting auxiliary device 120 establish a communication connection therebetween, and start a voice control function. When receiving a voice control command from a user, the terminal 110 determines an object (terminal or shooting assistance device) to be controlled by the voice control command through a voice recognition function. When the voice control instruction is used to control the auxiliary shooting device 120, the terminal 110 generates an operation instruction that can be recognized by the auxiliary shooting device 120 according to the voice control instruction, and sends the operation instruction to the auxiliary shooting device 120 through the communication connection, and the auxiliary shooting device 120 responds to the operation instruction to perform corresponding operations.
For example, when the voice control instruction is used to instruct the shooting assistance device 120 to adjust the shooting angle of the terminal 110 through the rotating mechanical structure, the terminal 110 generates a rotation operation instruction according to the voice control instruction and sends the rotation operation instruction to the shooting assistance device 120, and the shooting assistance device 120 controls the rotating mechanical structure to operate according to the rotation direction and the rotation angle indicated by the rotation operation instruction, so as to achieve the effect of changing the shooting angle of the terminal.
Referring to fig. 2, a flowchart of a method of an image capturing method according to an exemplary embodiment of the present application is shown, where the method is described as being applied to the terminal 110 shown in fig. 1, and the method may include the following steps.
In a possible implementation, in the shooting scenario, when the voice assistant function is awakened, the terminal receives the voice control instruction through the microphone. Wherein, the voice assistant function can be awakened by a preset awakening instruction. Optionally, the subsequent control process of the shooting assistance device is implemented by the voice assistant function.
And 202, identifying the voice control command, and determining a control object indicated by the voice control command, wherein the control object is a terminal or a shooting auxiliary device.
In the embodiment of the application, in a shooting scene, a user can initiate voice control on any object in a terminal or a shooting auxiliary device, and therefore after receiving a voice control instruction, the terminal needs to determine a control object indicated by the voice control instruction.
In some embodiments, the terminal converts the voice control instruction into a text instruction, and recognizes the text instruction, thereby determining the control object according to the recognition result. The terminal may recognize the word instruction through a Natural Language Processing (NLP) model to obtain a recognition result.
In other embodiments, the terminal may upload the converted text instruction to the server, and the server identifies the text instruction and feeds back the identification result to the terminal, which is not limited in this embodiment.
It should be noted that, when the terminal is connected to a plurality of shooting auxiliary devices that implement different auxiliary functions, the terminal may determine, according to the recognition result, a specific shooting auxiliary device to be controlled by the voice control instruction from the plurality of shooting auxiliary devices, which is not limited in this embodiment.
And step 203, responding to the control object as the shooting auxiliary equipment, and generating an operation instruction according to the voice control instruction, wherein the operation instruction conforms to the instruction format of the shooting auxiliary equipment.
In a possible implementation manner, when the voice control instruction is used for controlling the shooting auxiliary device, since the shooting auxiliary device cannot directly recognize and respond to the voice control instruction, in order to realize the control of the shooting auxiliary device, the terminal needs to generate an operation instruction which conforms to an instruction format supported by the shooting auxiliary device based on the voice control instruction.
Optionally, the operation instruction includes a function controlled by the voice control instruction and an adjustment amount corresponding to the function. For example, when the function controlled by the voice control command is a shooting angle adjustment function, the operation command includes an adjustment direction and an adjustment angle of the shooting angle.
And step 204, sending an operation instruction to the shooting auxiliary equipment through the communication connection with the shooting auxiliary equipment, wherein the shooting auxiliary equipment is used for executing corresponding operation according to the operation instruction.
Further, the terminal sends the operation instruction to the shooting auxiliary equipment through the communication connection, so that the shooting auxiliary equipment executes corresponding operation according to the operation instruction.
When the voice control instruction is used to control the terminal, the terminal adjusts the shooting parameters of the terminal according to the shooting parameters indicated by the voice control instruction and the parameter adjustment amount corresponding to the shooting parameters. For example, when the voice control instruction indicates that the adjusted shooting parameter is an aperture, the terminal determines an aperture adjustment amount according to the voice control instruction, so that the aperture parameter is adjusted on the basis of the current aperture size.
Besides, the terminal controls the shooting auxiliary device according to the voice control instruction, the shooting auxiliary device can also control the terminal (through communication connection), for example, a user can click a physical key on the shooting auxiliary device to control the terminal to perform shooting operation.
Compared with the prior art, the terminal can only send a simple shooting instruction to the terminal by the shooting auxiliary equipment, so that rapid shooting is realized without directly controlling the terminal, in the embodiment of the application, the terminal can recognize the control requirement of a user on the shooting auxiliary equipment by means of voice and intention recognition functions, and then send a corresponding operation instruction to the shooting auxiliary equipment, so that voice control on the shooting auxiliary equipment is realized, and the efficiency and convenience for controlling the shooting auxiliary equipment when the shooting auxiliary equipment auxiliary terminal is used for shooting are improved; moreover, voice recognition is performed by the terminal, an additional voice recognition component is not required to be arranged in the shooting auxiliary equipment, and the cost of realizing voice control by the shooting auxiliary equipment is reduced.
To sum up, in the embodiment of the present application, when the auxiliary terminal of the shooting auxiliary device is used for shooting an image, a user may send a voice control instruction to the terminal in a voice control manner, the terminal determines that the voice control instruction is used for controlling the terminal or the shooting auxiliary device, and when the voice control instruction is determined to be used for controlling the shooting auxiliary device, the generated operation instruction is further sent to the shooting auxiliary device, and the shooting control device executes a corresponding operation, so that voice control over the shooting control device is implemented; moreover, because the recognition of the voice control instruction and the generation of the operation instruction are realized by the terminal, the shooting auxiliary equipment only needs to respond to the operation instruction, so that the shooting auxiliary equipment does not need to be provided with an additional voice interaction component, and the realization cost of the voice control shooting auxiliary equipment is reduced.
In general, when a user adjusts through the voice control terminal and the shooting auxiliary device, the adjustment scale is not explicitly indicated in the voice control instruction, for example, when the shooting angle of the terminal needs to be adjusted through the shooting auxiliary device, the voice control instruction sent by the user is "the lens is slightly shifted to the left", rather than "the lens is shifted to the left by 15 °. In order to make the operation performed by the shooting auxiliary equipment according to the operation instruction meet the user's desire, the terminal needs to determine the adjustment amount of the target function in addition to the target function to be controlled based on the voice control instruction, and then indicates the target function through the operation instruction. The following description will be made using exemplary embodiments.
Referring to fig. 3, a flowchart of a method of an image capturing method according to another exemplary embodiment of the present application is shown, where the method is described as being applied to the terminal 110 shown in fig. 1, and the method may include the following steps.
The step 201 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.
And step 302, identifying the voice control command and determining a target function controlled by the voice control command.
In a possible implementation manner, after the terminal converts the voice control instruction into a text instruction, the text instruction is input into a pre-trained NLP model, so as to obtain probabilities corresponding to candidate functions output by the NLP model, and thus the candidate function corresponding to the highest probability is determined as a target function controlled by the voice control instruction, where the candidate functions include functions supported by the terminal in a shooting scene (such as a contrast adjusting function, a flash opening and closing function, an aperture size adjusting function, and the like) and functions supported by the shooting auxiliary device (such as adjusting left and right shooting angles, adjusting a shooting pitch angle, and adjusting a front and back position); moreover, the NLP model is obtained by training according to the sample word instruction containing the functional label, and the training process of the NLP model is not limited in the embodiment of the application.
Of course, the terminal may use other neural network models for identification besides using the NLP model, and this embodiment of the present application is not limited to this.
In an illustrative example, the terminal recognizes the voice control command 'angle is adjusted a little to the left' through the NLP model, and determines that the target function controlled by the voice control command is 'left and right shooting angle adjustment function'.
Further, the terminal compares the determined target object with a first function corresponding to the terminal and a second function corresponding to the shooting auxiliary equipment, so that a control object of the voice control instruction is determined.
And 303, responding to the target function belonging to the first function corresponding to the terminal, and determining that the control object is the terminal.
In one possible embodiment, the terminal stores a first function (set) corresponding to the terminal, and when the target function belongs to the first function, the control object is determined to be the terminal.
In one illustrative example, the first functionality associated with the terminal includes: and when the identification result indicates that the target function to be controlled is the 'focal length adjustment function', the terminal determines that the control object is the terminal.
And step 304, in response to that the target function belongs to a second function corresponding to the shooting auxiliary equipment, determining that the control object is the shooting auxiliary equipment.
In one possible embodiment, the terminal stores a second function (set) corresponding to the shooting assistance device, and when the target function belongs to the second function, the control object is determined to be the shooting assistance device.
Optionally, the second function is that after the terminal establishes a communication connection with the shooting assistance device, the shooting assistance device sends the shooting assistance device to the terminal through the communication connection, and stores the shooting assistance device in the terminal.
In an illustrative example, the corresponding second function of the shooting assistance apparatus includes: the terminal determines that the control object is the shooting auxiliary equipment when the recognition result indicates that the target function of the control is the left-right shooting angle adjusting function.
And step 305, responding to the control object being the shooting auxiliary equipment, and determining the target function controlled by the voice control instruction.
And when the control object is the shooting auxiliary equipment, the terminal further generates an operation instruction according to the target function controlled by the voice control instruction and the adjustment amount of the target function. Wherein, the target function can be obtained in the identification process.
In a possible implementation manner, the terminal detects whether the voice control command includes an explicit adjustment amount (i.e. a first adjustment amount) of the target function, and if so, the terminal generates an operation command according to the target function and the first adjustment amount. In some embodiments, the operation instruction includes a function identifier of the target function and the first adjustment amount.
Optionally, the terminal determines an adjustment amount keyword corresponding to the adjustment amount of the target function according to the determined target function, so as to determine whether the voice control instruction includes the first adjustment amount according to the adjustment amount keyword. For example, when the target function is a "left-right shooting angle adjustment function", the adjustment amount keyword may be degree.
In an illustrative example, as shown in fig. 4, the voice control command 42 received by the terminal 41 is "turn the camera to the left by 15 degrees", by recognizing the voice control command 42, the terminal 41 determines that the control target of the voice control command 42 is the photographing assisting device 43, determines that the target function controlled by the voice control command 42 is the "left and right photographing angle adjusting function", and extracts that the first adjustment amount of the target function is 15 degrees, thereby generating an operation command and transmitting the operation command to the photographing assisting device 43. After receiving the operation command, the shooting assistance device 43 performs an operation according to the operation command, and rotates the terminal 41 by 15 degrees to the left by rotating the mechanical structure.
And 307, performing image recognition on the framing picture in response to the fact that the voice control instruction does not contain the first adjustment amount corresponding to the target function, and obtaining an image recognition result.
In most cases, the user does not explicitly specify the amount of adjustment in the voice control command, but rather employs words such as "turn left slightly," "move forward slightly," and so forth. Since the shooting auxiliary device needs to perform corresponding operations according to the clear adjustment amount, when the voice control instruction does not include the first adjustment amount, the terminal needs to determine the clear adjustment amount.
In general, when a user views a viewfinder picture of the terminal and the display effect of a shooting object in the viewfinder picture does not meet the user's expectation, the user issues a voice control instruction, so that in one possible embodiment, the terminal determines the adjustment amount of the target function based on the image recognition result of the viewfinder picture and the target function controlled by the voice control instruction.
In some embodiments, the terminal identifies the photographic subject in the view through the image identification model, and further extracts parameters (including position, size, angle and the like) of the photographic subject in the view, so as to obtain an image identification result containing the photographic subject and the parameters of the subject.
And 308, determining a second adjustment amount corresponding to the target function according to the image recognition result.
Further, based on the obtained image recognition result, the terminal determines an adjustment amount that meets the user's control intention. In one possible embodiment, this step may include the following steps.
And 308A, determining original object parameters of the shot object in the view frame according to the image recognition result, and determining target object parameters of the shot object in the view frame according to the target function, wherein the object parameters comprise at least one of size parameters, position parameters or angle parameters.
Optionally, in this embodiment of the application, an image recognition result obtained by performing image recognition on the view frame includes an original object parameter of the photographic object, where the original object parameter is used to indicate at least one of a size, a position, and an angle of the photographic object in the current view frame. For example, the original object parameters include 100px × 200px (size parameter), (200px, 560px) (position parameter), and 10 ° (angle parameter).
Accordingly, the photographing assistant apparatus can change at least one of the size, position, and angle of the photographic subject in the through-view screen by performing the operation.
In order to achieve the shooting effect meeting the user's expectation, in one possible implementation, the terminal performs image recognition on the shot images in the album in advance, so as to construct the corresponding relationship among the shooting scene, the shooting object and the object parameter according to the image recognition result. Schematically, the correspondence is shown in table one.
Watch 1
| Shooting scene | Shooting object | Object parameters |
| Multi-person combined racket | Portrait of human | A size parameter A1, a position parameter B1, and an angle parameter C1 |
| Single-person landscape self-timer | Portrait of human | A size parameter A2, a position parameter B2, and an angle parameter C2 |
Correspondingly, when the adjustment amount of the target function is determined, the terminal searches the object parameters from the corresponding relation according to the current shooting object and the current shooting scene, and then determines the parameters corresponding to the target function in the searched object parameters as the target object parameters.
For example, the terminal finds out the object parameters including the size parameter a1, the position parameter B1 and the angle parameter C1 according to the current shooting scene "multi-person taking" and the shooting object "portrait", and when the target function controlled by the voice control command is the "left-right shooting angle adjustment function", the terminal determines the angle parameter C1 as the target object parameter.
Of course, in addition to performing image recognition on the local captured image to construct the above correspondence, the terminal may also obtain the correspondence from the server (obtained by analyzing a large number of images by the server), which is not limited in this embodiment.
And 308B, determining a second adjustment amount according to the target object parameter and the original object parameter, wherein after the shooting auxiliary equipment adjusts the target function according to the second adjustment amount, the object parameter of the target object in the view finding picture is the target object parameter.
Further, the terminal determines a second adjustment amount required to be adjusted when the object parameter of the shooting object in the framing picture is converted into the target object parameter according to the difference value between the target object parameter and the original object parameter, so as to generate an operation instruction based on the second adjustment amount.
In a possible implementation manner, the terminal is provided with a mapping relationship between the parameter difference and the adjustment amount, and when determining the second adjustment amount of the target function, the terminal determines the parameter difference between the target object parameter and the original object parameter, so as to determine the second adjustment amount corresponding to the target function according to the mapping relationship between the parameter difference and the adjustment amount, where the adjustment amount and the parameter difference have a positive correlation.
In some embodiments, the mapping between different parameters and adjustment amounts is different. For example, the mapping relationship between the angle parameter and the adjustment amount can be expressed as: and a is bx + c, wherein a is an adjustment amount, b and c are preset coefficients, and x is an angle parameter.
Similar to the process of generating the operation instruction in step 306, the terminal generates the operation instruction according to the target function and the second adjustment amount.
In an exemplary example, as shown in fig. 5, the terminal 51 receives a voice control command 52 "turn the camera to the left a little bit", and by recognizing the voice control command 52, the terminal 51 determines that the control target of the voice control command 52 is the photographing assisting device 53, and determines that the target function controlled by the voice control command 52 is the "left and right photographing angle adjusting function".
Since the control command 52 does not include an explicit angle adjustment amount in the voice, the terminal 51 performs image recognition on the current viewfinder frame 511, determines an original object parameter of the photographic subject according to the image recognition result, determines a second adjustment amount (for example, 15 degrees) of the angle parameter according to the target object parameter and the original object parameter of the photographic subject, and generates an operation command according to the second adjustment amount and the "left and right photographic angle adjustment function". After receiving the operation instruction, the shooting assistance device 53 rotates the terminal 51 by 15 degrees to the left through the rotating mechanism.
And 310, sending an operation instruction to the shooting auxiliary equipment through the communication connection with the shooting auxiliary equipment, wherein the shooting auxiliary equipment is used for executing corresponding operation according to the operation instruction.
The step 204 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.
In this embodiment, the terminal identifies the voice control instruction, determines the target function controlled by the voice control instruction, and further determines the control object according to the target function, so that the accuracy of the determined control object is improved.
In addition, in the embodiment, when the voice control instruction contains a clear adjustment amount, the terminal generates an operation instruction according to the adjustment amount and the target function; when the voice control instruction does not contain a clear adjustment amount, the terminal identifies the view-finding picture through images, so that the adjustment amount of the target function is determined based on the image identification result, an operation instruction is generated, and the intelligent degree of voice control is improved.
Since the adjustment range of the photographing auxiliary device is limited (for example, only 180-degree rotation can be achieved), in the process of generating the operation instruction based on the adjustment amount, the terminal needs to determine whether the photographing auxiliary device can complete the adjustment of the target function based on the determined adjustment amount. In some embodiments, based on fig. 3, as shown in fig. 6, step 305 further includes step 311, step 306 may be replaced by step 3061, and step 309 may be replaced by step 3091.
And 311, determining an upper limit of an adjustment amount corresponding to the target function in the current state according to the state information of the shooting auxiliary equipment.
In a possible implementation manner, after the target function controlled by the voice control instruction is determined, the terminal acquires the state information from the shooting auxiliary device through communication connection, so that the upper limit of the adjustment amount of the target function in the current state is determined according to the state information.
Optionally, the state information includes current function parameters of each function supported by the shooting assistance device. For example, the status information includes a current pan angle, a current pan tilt angle, a current fore-and-aft position, and the like of the shooting assistance apparatus.
Further, the terminal determines the upper limit of the adjustment amount of the target function according to the upper limit of the function parameter of the target function and the current function parameter. Wherein, the upper limit of the adjustment amount is the upper limit of the function parameter-the current function parameter.
In an illustrative example, when the target function is a left-right photographing angle adjusting function, the terminal determines that the upper limit of the adjustment amount is 60 degrees according to the upper limit of the function parameter of the left-right photographing angle adjusting function of 180 degrees and the current function parameter of 120 degrees.
When the voice control instruction comprises a first adjustment amount corresponding to the target function, the terminal detects whether the first adjustment amount is smaller than or equal to the upper limit of the adjustment amount, and if the first adjustment amount is smaller than or equal to the upper limit of the adjustment amount, a corresponding operation instruction is generated.
Optionally, if the first adjustment amount is greater than the adjustment amount upper limit, the terminal performs an adjustment prompt in a predetermined manner. The predetermined mode includes but is not limited to a text mode, a voice mode and an animation mode. For example, the terminal prompts the user to manually adjust the shooting auxiliary device in a text manner.
And when determining a second adjustment amount corresponding to the target function, the terminal detects whether the second adjustment amount is less than or equal to the upper limit of the adjustment amount, and if the second adjustment amount is less than or equal to the upper limit of the adjustment amount, a corresponding operation instruction is generated.
Optionally, if the second adjustment amount is greater than the upper limit of the adjustment amount, the terminal performs an adjustment prompt in a predetermined manner. The predetermined mode includes but is not limited to a text mode, a voice mode and an animation mode. For example, the terminal prompts the user to manually adjust the shooting auxiliary device in a text manner.
When the voice control instruction does not contain a clear adjustment amount, the terminal can instruct the shooting auxiliary equipment to gradually adjust according to a certain adjustment amount besides determining the adjustment amount by adopting the image recognition mode, and after the shooting auxiliary equipment adjusts the terminal to a state expected by a user, the user can control the shooting auxiliary equipment to stop adjusting through voice. In a possible implementation manner, after the step 305, in response to that the voice control instruction does not include the first adjustment amount corresponding to the target function, the terminal generates an operation instruction according to the target function and an adjustment rate corresponding to the target function, where the adjustment rate is used to represent the adjustment amount corresponding to the target function in the unit time length.
The adjusting rate can be set by the terminal, or can be set by the shooting auxiliary equipment and sent to the terminal. For example, when the target function is a "left-right photographing angle adjusting function", the adjustment rate may be 5 degrees/second, and when the target function is a "front-rear position adjusting function", the adjustment rate may be 1 cm/second.
And the terminal generates an operation instruction according to the target function and the adjustment rate, and after the operation instruction is sent to the shooting auxiliary equipment, the shooting auxiliary equipment circularly executes corresponding operation according to the adjustment rate in the operation instruction.
After the above step 310, in response to receiving the voice control stop instruction, the terminal sends an operation stop instruction to the shooting assistance apparatus through a communication connection with the shooting assistance apparatus. Correspondingly, after the shooting auxiliary equipment receives the operation stop instruction, the shooting auxiliary equipment stops executing corresponding operation.
In a possible implementation manner, after the terminal sends the operation instruction to the shooting auxiliary equipment, whether a voice control stop instruction is received or not is detected, and when the voice control stop instruction is received, the operation stop instruction is sent to the shooting auxiliary equipment. The voice control stop instruction may be an instruction including a preset stop keyword.
Illustratively, as shown in fig. 7, the voice control command 72 received by the terminal 71 is "turn the camera a little to the left", and by recognizing the voice control command 72, the terminal 71 determines that the control target of the voice control command 72 is the shooting assistance apparatus 73, and determines that the target function controlled by the voice control command 72 is "left-right shooting angle adjustment function".
Since the control command 72 does not include an explicit angle adjustment amount in the voice, the terminal 71 generates an operation command according to the target function and the adjustment rate (for example, 5 degrees/second), and transmits the operation command to the shooting assistance apparatus 73. Upon receiving the operation instruction, the shooting assistance apparatus 73 adjusts the shooting angle to the left in accordance with the adjustment rate.
When receiving the voice control end instruction 74 "OK", the terminal 71 sends an operation stop instruction to the photographing auxiliary apparatus 73, and the photographing auxiliary apparatus 73 stops adjusting the photographing angle to the left upon receiving the stop instruction.
In the embodiment, after receiving the voice control instruction, the terminal controls the shooting auxiliary equipment to perform corresponding operation circularly according to the adjustment rate, and when receiving the voice control ending instruction, the terminal controls the shooting auxiliary equipment to stop the adjustment operation, so that a user does not need to explicitly indicate the adjustment amount, and the intelligence degree and the accuracy of the voice control shooting auxiliary equipment are improved.
