Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a schematic structural diagram of a system for controlling a camera according to an embodiment of the present disclosure. As shown in fig. 1, the system includes:
a camera 101, a server 102, and a terminal device 103. The camera 101, for example, a digital camera, is connected to the server 102 via an HDMI interface and a USB interface, and remote communication, including wireless communication, can be performed between the server 102 and the terminal device 103 via a network.
The server 102 is configured to acquire an image captured by the digital camera and transmit the image to the terminal device 103. The terminal device 103 is configured to receive a camera control instruction input by a user, and send the camera control instruction to the server, so that the server 103 sends the camera control instruction to the digital camera, and the digital camera executes the camera control instruction. The camera control command includes adjusting a focal length, parameter settings, etc. of the digital camera.
Therefore, the user can check the images shot by the digital camera in real time through the terminal equipment, and the user can control and operate the digital camera through the terminal equipment far away from the camera, so that the digital camera is convenient to use and is not limited by distance.
How the system for controlling a camera provided in the present embodiment controls a camera will be described below. Fig. 2 is a signaling interaction diagram of a method of controlling a camera according to an embodiment of the present disclosure. As shown in fig. 2, the method includes:
s201, a server acquires a framing image of a camera;
s202, the server sends the framing image to the terminal equipment, so that the terminal equipment presents the framing image to a user.
Illustratively, the server acquires a view image of the camera and then encodes the view image to generate an encoded view image; and then the coded view finding image is sent to the terminal equipment.
By encoding the through image and transmitting the encoded through image to the terminal device, the security of data in the transmission process can be improved.
S203, the terminal equipment receives the framing image sent by the server and displays the framing image to a user, so that the user can operate the camera according to the framing image.
In the implementation, after receiving the framing image sent by the server, the terminal equipment decodes the framing image to generate a decoded framing image; and displaying the decoded viewfinder image to a user so that the user can operate the camera according to the decoded viewfinder image. The through image can be restored by decoding the through image.
Illustratively, the terminal device may display the decoded through-view image on a screen, and present the decoded through-view image to a user. If the user needs to operate the camera according to the decoded viewfinder image after viewing the decoded viewfinder image, for example, the brightness of the decoded viewfinder image is insufficient, the exposure parameter needs to be adjusted, or the viewfinder image is normal, and the digital camera needs to be controlled to shoot or record video, an operation interface of the digital camera can be opened on the terminal device, and on the operation interface, various operations are performed on the camera, for example, parameters such as adjusting the exposure parameter, white balance, focal length, etc., shooting, recording video, etc., so that the user can operate the digital camera through a keyboard and a mouse, and can also operate the digital camera through a touch screen, etc.
S204, the terminal equipment receives a camera operation event input by a user, wherein the camera operation event comprises cursor movement information generated when the user operates a keyboard and mouse device or a touch screen of the terminal equipment;
and S205, the terminal equipment determines a camera control instruction corresponding to the cursor movement information.
Illustratively, function keys such as "delete", "shoot", "view", and the like may be provided on the operation interface of the terminal device, and when a user clicks the function keys such as "delete", "shoot", "view", and the like on the operation interface through a keyboard and mouse device or a touch screen of the terminal device, a camera operation event may be generated, where the camera operation event includes cursor movement information generated when the user operates the keyboard and mouse device or the touch screen of the terminal device, that is, cursor movement information generated on the operation interface when the user clicks the function keys such as "delete", "shoot", "view", and the like.
Presetting control instructions corresponding to all function keys on the digital camera on the terminal equipment; firstly, according to cursor movement information of a user operation event on an operation interface, judging an operation function which the user operation event is expected to execute, such as 'shooting'; then, a camera control instruction corresponding to the operation function is found from camera control instructions corresponding to function keys on a preset digital camera, for example, the control instruction corresponding to the "shooting" function is a shooting control instruction, that is, a "shutter" key is pressed once.
Since the digital camera cannot recognize the cursor movement information, the cursor movement information in the camera operation event needs to be converted into a camera control instruction that can be recognized by the digital camera, and then the digital camera can execute the camera control instruction to realize corresponding key operation.
And S206, the terminal equipment sends the camera control instruction to a server.
S207, the server receives a camera control instruction sent by the terminal equipment;
s208, the server sends the camera control instruction to the camera so that the camera can execute the camera control instruction.
The camera control command is taken as a shooting command for example. And after the terminal equipment determines that the camera control instruction corresponding to the cursor movement information is a shooting instruction, the shooting instruction is sent to the server. And the server receives the shooting instruction sent by the terminal equipment and sends the shooting instruction to the digital camera. After receiving the camera shooting instruction, the digital camera executes the shooting instruction, namely, executes the operation of pressing the shutter button once to shoot photos and/or videos.
Further, after the camera executes the shooting instruction, the shot pictures and/or videos are stored and picture and/or video files are generated. The server acquires photos and/or video files shot by the camera from the digital camera; and send the photo and/or video file to the terminal device. And the terminal equipment receives and stores the photo and/or video file sent by the service. After storage, if a viewing instruction of a user is received, the photo and/or video file is displayed on a display, and the photo and/or video in the photo and/or video file is displayed to the user.
According to the method for controlling the camera, the server can acquire the framing image of the camera; sending the framing image to a terminal device so that the terminal device can display the framing image to a user; the terminal equipment can receive the framing image sent by the server and display the framing image to a user so that the user can operate the camera according to the framing image; receiving a camera operation event input by a user, wherein the camera operation event comprises cursor movement information generated when the user operates a keyboard and mouse device or a touch screen of the terminal device; determining a camera control instruction corresponding to the cursor movement information; sending the camera control instruction to a server; the server can also receive a camera control instruction sent by the terminal equipment; and the camera control instruction is sent to the camera so that the camera can execute the camera control instruction, a user can check images shot by the camera in real time through the terminal equipment, and the user can carry out remote control operation on the camera through the terminal equipment far away from the camera, so that the camera control instruction is convenient to use and is not limited by distance.
The method for controlling the camera according to the embodiment of the present disclosure is further described in detail with reference to fig. 3 to 7.
Referring to fig. 3, fig. 3 is a schematic diagram of a connection relationship between a camera and a server according to an embodiment of the present disclosure. As shown in fig. 3, the digital camera is connected to the server, i.e., the S-side device, through the USB interface and the HDMI interface, respectively. The HDMI is used for collecting a real-time view picture of the digital camera, and the USB is used for transmitting a camera operation event of a user and retrieving a shot picture.
Fig. 4 is a schematic diagram of a connection relationship between a terminal device and a server according to an embodiment of the present disclosure. The terminal equipment, namely R-end equipment, comprises a display and a keyboard and mouse. In addition, the R-end equipment can be connected with USB storage equipment. After the R-side device is connected to the S-side device through the ethernet, the real-time view image of the digital camera can be obtained through the image transmission channel, and the digital camera is reversely controlled through the reverse control channel, such as adjusting exposure parameters, white balance, focal length, and other parameters of the digital camera. The digital camera can reflect the result of the adjustment in the viewfinder, that is, the real-time view image collected by the S-side device is transmitted to the screen of the R-side device, and the user can operate the R-side device in the same manner as the camera is locally operated.
After the exposure parameters are adjusted to meet the requirements, the R-end equipment can be operated to shoot, and the pictures and/or videos shot by the digital camera are stored into pictures and/or video files. The S-end equipment can retrieve the photo or video file to the S-end equipment through the USB interface. In order to ensure that the photos and/or videos are not compressed, and the pixel values of the photos and/or videos are kept unchanged so as to improve the experience of a user in watching the photos or videos, after the S-end device acquires the photos and/or video file, the S-end device does not perform image coding and decoding operations on the photos and/or videos in the file, directly transmits the photos and/or videos to the R-end device, and downloads the photos and/or videos to the USB storage device or other network storage media connected with the R-end device through the R-end device.
In the system of controlling the camera, which is formed by combining fig. 3 and fig. 4, the S-side device collects the framing image from the image source device, i.e., the digital camera, encodes the collected framing image, transmits the encoded framing image to the R-side device, and the encoded framing image is input to the display after being decoded by the R-side device; and the R-end equipment sends the user operation event to the S-end equipment, the S-end equipment sends the user operation event to the image source equipment, and the image source equipment executes the operation event. It can be understood that two channels exist between the S-side device and the R-side device, an image transmission channel and a reverse control channel.
How the system for controlling the camera, which is composed in conjunction with fig. 3 and 4, controls the camera for remote photographing, will be described below. Fig. 5 is a flowchart of a method of controlling a camera according to an embodiment of the present disclosure. As shown in fig. 5, the method includes:
s501, the S-end equipment collects the framing image of the digital camera, codes the collected framing image and sends the coded data to the R-end equipment through an image transmission channel.
And S502, the R-end equipment decodes the received coded data and displays the coded data on a connected display.
S503, the R-end equipment acquires a camera operation event, and converts the camera operation event into a camera control instruction corresponding to the digital camera, wherein the camera operation event comprises cursor movement information, and the camera control instruction comprises key information.
In this step, the user opens an operation interface of the digital camera on the R-side device, and operates various functions on the operation interface, for example, adjusting parameters such as exposure parameters, white balance, focal length, etc., shooting, recording, etc., and the user may operate through a keyboard and a mouse, or may operate through other modes such as a touch screen, etc.; the R-end equipment acquires a camera operation event input by a user, and for convenience of explanation, the operation event directly acquired by the R-end equipment can be recorded as the camera operation event, and the camera operation event can include cursor movement information generated by key mouse or touch screen operation; the reason why the R-side device converts the camera operation event into the camera control command that can be analyzed by the digital camera is that the digital camera usually performs key operation, and cannot recognize cursor movement information, and the cursor movement information in the camera operation event needs to be converted into key information that can be recognized by the digital camera.
As shown in fig. 6 and 7, it can be seen that all functions of such digital cameras are implemented by keys, and therefore, cursor movement information in a camera operation event needs to be converted into key information that can be recognized by the digital camera.
Specifically, function keys such as "delete", "shoot", "check" and the like may be set on an operation interface of the R-side device, and each function key on the digital camera is preset in the R-side device to correspond to a camera control instruction, where the camera control instruction includes key information; firstly, according to cursor movement information in a camera operation event on an operation interface of the R-end device, judging an operation function which is expected to be executed by the camera operation event, such as 'shooting'; then, a camera control instruction corresponding to the operation function, for example, a shooting instruction corresponding to a "shooting" function, is found from camera control instructions corresponding to function keys on a preset digital camera, where the shooting instruction includes key information: the "shutter" button is pressed once. In this embodiment, a camera control instruction may be generated according to cursor movement information in a camera operation event, for example, according to cursor movement information of a "shooting" function key clicked by a user on an operation interface of the R-side device, the camera control instruction corresponding to the cursor movement information is determined to be a shooting instruction, and the shooting instruction includes key information of "pressing a" shutter "key once".
It should be noted that, if the digital camera is a normal digital camera and the operation interface on the digital camera is a touch screen, as shown in fig. 8, the layout of the operation interface of the R-side device and the operation interface on the digital camera may be set to be the same, so that the digital camera can identify the cursor movement information in the camera operation event, and the camera operation event may be directly sent to the S-side device without converting the camera operation event, and the S-side device forwards the camera operation event to the digital camera for execution.
The operation interface of the R-side device may be in the form of an Application (APP) interface, or may be in the form of a web page.
S504, the R-end equipment sends the camera control instruction to the S-end equipment through a reverse control channel; the S-terminal equipment sends the camera control instruction to the digital camera; the digital camera executes according to the camera control instruction.
It can be understood that the camera control command may include control commands for shooting, recording, viewing photos, adjusting parameters, etc., and the camera may implement the function of the camera control command through corresponding keys on the digital camera.
It should be noted that, in the prior art, a camera with a network function may be connected to a computer to implement remote shooting, and in general, the camera has a low definition for taking a picture, and cannot adjust parameters affecting the shooting quality, such as a focal length, an exposure parameter, and a white balance of shooting. The invention can remotely control the digital camera through the S-terminal device and the R-terminal device to obtain the original file which is shot by the digital camera and is not subjected to coding and decoding loss, wherein the original file comprises the file in the RAW format, so that the shot picture or video is clearer, and the parameters of the digital camera, such as exposure parameters, white balance, focal length and the like, can be adjusted through the S-terminal device and the R-terminal device.
