TECHNICAL FIELD

The present disclosure relates to a video photographing processing method, a video photographing processing apparatus, and a video photographing processing system.

BACKGROUND

Currently, cameras, especially small and light-weight camera products, e.g., sports cameras and aerial cameras, have reached the ability to output high-quality and full high definition (HD) 1080p video streams.

However, due to requirements on the volume and weight, or because battery life needs to be prioritized as much as possible, these camera products cannot be equipped with a very high-performance processor. Therefore, generally, when photographing is performed, video information is directly stored locally in the camera via a DSP. Limited by a processing capacity, an output video stream for monitoring is only be sent as a low-definition video to the human-machine interface/HDMI monitor of the mobile phone application by performing compression and down sampling via rate control, and the like.

Limited by hardware, the camera products only perform some simple filter processing in the DSP, such as applying a formulated LUT for color changes, and the like, and cannot achieve complex effects such as beautification and complex filters requiring relatively high computing power. The tendency is particularly obvious, especially for a photographing apparatus outputting a high-definition video,

Nowadays, due to an increasing demand for entertainment, more and more users are beginning to apply more advanced processing such as beautification or complex filters to the video during short video photographing, self-portrait, or live broadcast. With the rapid development of the performance of terminals led by mobile phones, mobile phones have reached the ability to perform the complex processing on the video streams, and can output videos that have undergone complex filter processing and beautification processing. However, mobile phones cannot replace cameras such as sports cameras and aerial cameras to photograph certain scenes.

SUMMARY

In accordance with the disclosure, there is provided a photographing apparatus including a processing circuit configured to obtain video data and a communication circuit configured to send the video data and a processing instruction to a processing apparatus. The processing instruction instructs the processing apparatus to process the video data.

DETAILED DESCRIPTION OF THE EMBODIMENTS

FIG. 1 is a conceptual diagram schematically showing a photographing processing system of the present disclosure. As shown in FIG. 1, the photographing processing system includes a photographing apparatus 1 and an external processing apparatus 2. The photographing apparatus 1 includes functional units for photographing (e.g., a camera, a photographing member, related circuits, and the like) and other functional units (e.g., a housing member, a mechanical member, a communication module, and the like).

The external processing apparatus 2 can refer to a device configured to process video data sent from the photographing apparatus 1 via a communication connection, and separate from the photographing apparatus 1.

The photographing apparatus 1 in FIG. 1 is a handheld gimbal camera including a gimbal and a camera (equivalent to an image acquisition device) arranged at the gimbal. A photographing angle of the camera can be adjusted by adjusting an attitude of the gimbal.

The external processing apparatus 2 in FIG. 1 is a mobile phone. The handheld gimbal camera can be plugged into a charging port of the mobile phone (e.g., iOS/Android) via a detachable interface accessory or can be plugged into the mobile phone indirectly via an interface adapter. Thus, they can establish the communication connection. In another situation, they can also establish the connection via a wireless communication, such as WiFi, Bluetooth, NFC, and the like. An application program for processing the video data can be installed in the mobile phone, and the application program can be executed by the processor of the mobile phone to process the video data.

In FIG. 1, the photographing apparatus 1 is showed as the handheld gimbal camera, which is merely an example and is not limited herein. The photographing apparatus 1 may be another existing device, such as a sports camera, an aerial camera, or the like, as long as it can photograph video and establish the communication connection with the external processing apparatus 2.

In FIG. 1, a handle is shown as a mobile platform carrying the gimbal, which is merely an example and is not limited herein. The mobile platform may also be an unmanned aerial vehicle (UAV), a remote-control vehicle, or the like.

Regarding the communication connection, a communication connection of existing technologies can be used. It can be a wireless connection, such as a Wi-Fi, a mobile network, and the like, or a wired connection (including a connection via a data line and a connection via an interface adapter, and the like), such as USB2.0, USB3.0, and the like. It is also possible that the photographing apparatus 1 and the external processing apparatus 2 can be respectively connected to an Internet via the wireless network, and the connection between them can be realized via the Internet to send data. As long as the communication connection can satisfy the video transmission requirements, it can be used in the present disclosure.

In FIG. 1, the external processing apparatus 2 is shown as a mobile phone, which is merely an example and is not limited herein. The external processing apparatus 2 may be another existing device, such as a tablet computer as a mobile terminal, or a desktop personal computer, as long as it can process the video data from the photographing apparatus 1 and can establish the connection with the photographing apparatus 1 via the communication (including a wired network, a wireless network, the Internet, and the like).

Hereinafter, the photographing processing method of the present disclosure is described with reference to FIG. 2. FIG. 2 is a flowchart showing the photographing processing method of the present disclosure.

The photographing processing method of the present disclosure includes: establishing the communication connection between the photographing apparatus and the external processing apparatus (S1), sending, by the photographing apparatus, the obtained video data to the external processing apparatus (S2), sending, by the photographing apparatus, a processing instruction to the external processing apparatus (S3), and processing, by the external processing apparatus, the video data according to the processing instruction (S4).

If a video recording start instruction is provided, the photographing processing method of the present disclosure can be started. The video recording start instruction can be provided on the photographing apparatus 1, for example, can be turned on from a displayed menu on a screen of the photographing apparatus 1, or can be turned on via an operation button on it. It can also be provided on the external processing apparatus 2, for example, can be turned on from a displayed menu on a screen of the external processing apparatus 2, or can be turned on via an operation button on it (e.g., double-press a volume key/lock screen key of the mobile phone, and the like, it can be set according to a specific type of the device). It can also be provided via a communication of a device other than them.

Hereinafter, the photographing processing method of the present disclosure will be described in detail below.

At S1, the photographing apparatus establishes the communication connection with the external processing apparatus.

In some embodiments, after the video recording start instruction is provided, the photographing apparatus 1 and the external processing apparatus 2 can establish the communication connection. The communication connection can be a wired connection via a data cable or a plug-in interface, or a wireless connection such as WiFi, Bluetooth, NFC, and the like. In some cases, a communication connection confirmation process may be required by the photographing apparatus 1 and the external processing apparatus 2, i.e., clicking to confirm the connection on one or both of the devices to complete the communication connection. In other cases, the photographing apparatus 1 and the external processing apparatus 2 may not require the communication connection confirmation process. For example, the external processing apparatus 2 has been configured to use by the photographing apparatus 1. When the video recording start instruction is provided, the communication connection between them can be automatically completed.

In some other embodiments, it is also possible to always maintain the communication connection between the photographing apparatus 1 and the external processing apparatus 2, and after the start instruction is provided, the processing after process S2 can be started.

At S2, the photographing apparatus sends the obtained video data to the external processing apparatus.

In a state that the communication connection is established between the photographing apparatus 1 and the external processing apparatus 2, the photographing apparatus 1 can shoot, and original video data can be obtained by a photographing member. The original video data can refer to video images obtained by the photographing member, e.g., a CMOS image sensor, a CCD image sensor, and the like, and converted into video data of electrical signals. Then, a processing circuit (including a processor, an encoder, and the like) of the photographing apparatus 1 can perform a first processing operation on the original video data to obtain the first video data. The first processing operation can refer to a processing operation performed on the original video data directly obtained by an image sensor in the processing circuit of the photographing apparatus 1, for example, compression encoding the original video data to generate an encoded transmission video stream. In some embodiments, the compression encoding herein may be H.264 and H.265 standard compression encoding, and the corresponding first video data is H.264 and H.265 video streams. Of course, other compression encoding algorithms can also be used as needed.

In addition, the first processing operation may also include performing image editing processing on the original video data, and then performing the compression encoding, or performing the image editing processing on the compression encoded video data to obtain the first video data. For example, the processing circuit of the photographing apparatus 1 may perform cropping processing on image frames of the original video data.

In some cases, the photographing apparatus 1 can be a sports camera or a gimbal camera, which cannot use a processor having a stronger processing capability due to volume limitations or cost limitations. Due to hardware limitations, the photographing apparatus 1 can only perform the processing with relatively low processing capabilities, but cannot implement advanced functions such as beautification, complex filters, special effects overlay, and the like. Therefore, the photographing apparatus 1 can send the obtained first video data to the external processing apparatus 2 via the communication connection. For example, a small gimbal camera detachably plugged into a mobile phone can send the first video data to the mobile phone via a data port, or a gimbal camera establishing a WiFi/Bluetooth/NFC communication connection with the mobile phone via a wireless communication can send the first video data to the mobile phone.

During a transmission of the first video data, a storage function of the photographing apparatus 1 can be turned off, and the first video data is not stored in the photographing apparatus 1, such that the processing capability of the photographing apparatus 1 can be more concentrated on the transmission of the first video data. That is, the processing capability of the processor of the photographing apparatus 1 can be used for the compression encoding and image transmission, thereby enabling a higher-definition video data transmission.

At S3, the photographing apparatus sends the processing instruction to the external processing apparatus.

In some embodiments, the user may operate the photographing apparatus 1 to send the processing instruction to the external processing apparatus 2 or the photographing apparatus 1 may automatically push the processing instruction to the external processing apparatus 2. For example, a user can use the photographing apparatus 1 (e.g., a gimbal camera) to photograph a video, and the photographing apparatus 1 can send the first video data to the external processing apparatus 2 (e.g., a mobile phone) via the communication connection. During the transmission process, or before or after the transmission process, the user can operate the photographing apparatus 1, e.g., a key operation or touch screen operation, to send the processing instruction to the external processing apparatus 2. The processing instruction can be used to instruct the external processing apparatus to perform a second processing operation on the first video data.

A sequence between processes S2 and S3 is not limited, i.e., the photographing apparatus 1 may first send the processing instruction to the external processing apparatus, and then send the first video data to the external processing apparatus 2, or vice versa. In addition, it is also possible to send the processing instruction to the external processing apparatus 2 while starting to send the first video data.

At S4, the external processing apparatus processes the video data according to the processing instruction.

The external processing apparatus 2 that has received the processing instruction can perform the second processing operation on the first video data.

The second processing operation can be different from the first processing operation, and the second processing operation can occupy more computing resources of the processor than the first processing operation, such as beautification processing, filter processing, special effect overlay processing, and the like.

When a high-definition video is being processed, a lot of computing resources will be occupied and a greater power will be consumed. Therefore, a function capable of executing the second processing operation is not provided in the photographing apparatus 1, but the function is executed in the external processing apparatus 2 such as a mobile phone.

After performing the second processing operation on the first video data, the external processing apparatus 2 can generate second video data on the basis of the first video data processed with, for example, the beautification processing, filter processing, special effect overlay processing, and the like.

The external processing apparatus 2 can store the second video data in its internal storage space, or may also upload the second video data to a cloud space on a network for storage. The storage may be executed according to a storage instruction from the photographing apparatus 1 or may be automatically executed by the external processing apparatus 2.

Hereinafter, the processing performed on the side of the photographing apparatus 1 will be described with reference to FIG. 3. FIG. 3 is a flowchart showing a photographing-apparatus-side processing method in the photographing processing method of the present disclosure.
