The following describes in detail the video recording data storage method provided in the embodiment of the present application with reference to the above-described endoscopic imaging system and endoscopic imaging host.
Referring to fig. 4, fig. 4 is a flowchart illustrating a video data storage method according to an embodiment of the present application. The video data storage method is applied to the endoscope camera host.
As shown in fig. 4, the video data storage method includes steps S101 to S105.
Step S101, acquiring an image signal of a target area from an endoscope camera, and processing the image signal.
The camera host firstly acquires an image signal of a target area acquired by the camera from the camera of the endoscope, the image signal is corresponding imaging information acquired by the camera receiving an optical signal of the endoscope, and then the image signal is processed by the image processing board card assembly.
And S102, converting and outputting the processed image signals, and recording and storing the output image data to an external storage device, wherein the external storage device is in communication connection with the camera host.
Then, the image signal processed by the image processing board card assembly is converted and output by the image output board card assembly (for example, the image signal is converted and output into 2K format video data, or 4K format video data, etc.), and then the image data output by the image output board card assembly is recorded and stored to an external storage device in communication connection with the camera host, where the external storage device may be a usb disk, and the number of the external storage devices may be one or more to ensure storage of the video data.
Step 103, when a shutdown instruction for controlling the camera host to be closed is received, determining whether the camera host is still in a recording state.
In order to avoid the problem that the camera host is shut down due to misoperation of a user in the process of recording and storing image data output by the image output board card assembly, and further the recorded image data is lost or the external storage device is damaged, when the camera host detects a shutdown instruction for controlling the camera host to be shut down, whether the camera host is still in a recording state or not is determined.
In an embodiment, the camera host records and stores the output image data to the external storage device through a video board card, and in order to accurately determine whether the camera host is still in a recording state, the following specific steps may be adopted: determining whether the state identifier of the video board card is a preset state identifier; if the state identifier is not a preset state identifier, determining that the camera host is still in a recording state; and if the state identifier is a preset state identifier, determining that the camera host is not in a recording state. The video board card has the function of judging the video state and records the video state by the state identifier.
That is, the camera host can record and store the output image data to the external storage device through the video board card, so that whether the camera host is still in a recording state can be determined by judging the working state of the video board card.
For example, the operating state of the video board card includes an operating state and a closing state, and the operating state of the video board card may be represented by a state identifier, for example, the state identifier "user", "user" true "indicates that the operating state of the video board card is the operating state, and" user "false" indicates that the operating state of the video board card is the closing state. The camera host takes an identifier "user ═ false" when the working state of the video board card is in the off state as a preset state identifier. Therefore, the camera host can acquire the current state identifier of the video board card, and the current working state of the video board card is judged by judging whether the current state identifier of the video board card is the preset state identifier. If the current status identifier of the video board card is not the preset status identifier "user ═ false", the current working state of the video board card can be determined to be the running state, so that the camera host can be determined to be still in the recording state. If the current status identifier of the video board card is the preset status identifier "user ═ false", the current working state of the video board card can be determined to be the off state, so that the camera host can be determined not to be in the recording state.
In an embodiment, in order to accurately determine whether the camera host is still in the recording state, specifically, the following steps may be adopted: determining whether the external storage device is in a data writing state; if the external storage equipment is in a data writing state, determining that the camera host is still in a recording state; and if the external storage equipment is not in a data writing state, determining that the camera host is not in a recording state.
For example, when the camera host is still in the recording state, the external storage device in communication connection with the camera host may still be in the data writing state, and thus, the camera host may determine whether the camera host is still in the recording state by determining whether the external storage device is in the data writing state. If the external storage device is in a data writing state, the camera host can be determined to be still in a recording state; if the external storage device is not in the data writing state, it can be determined that the camera host is not in the recording state.
In an embodiment, in the process of recording and storing image data output by the image output board card assembly, if a shutdown instruction is detected, in order to enable a user to clearly understand the recording state of the image data by the camera host, after determining whether the camera host is still in the recording state, a prompt message is generated and displayed, where the prompt message at least includes information indicating that the camera host is in the recording state.
For example, the prompt message may be a text message for prompting the user that the camera host is in the recording state, may be a voice message for prompting the user that the camera host is in the recording state, or may be a light with a specific color (for example, flashing red light) for prompting the user that the camera host is in the recording state, so as to remind the user whether to shut down the camera host, thereby ensuring the security and integrity of the recorded data.
And step S104, if the camera host is still in the recording state, delaying the response of the shutdown instruction until the recording state is determined to be finished, responding to the shutdown instruction to close the camera host.

Therefore, the safety and the integrity of the video data are ensured, and the damage to the external storage equipment can be avoided.
Referring to fig. 5, fig. 5 is a schematic flowchart of another video data storage method according to an embodiment of the present application.
As shown in fig. 5, the method includes steps S201 to S205.
Step S201, acquiring an image signal of a target region from an endoscope camera, and processing the image signal.
Wherein, the current area where the endoscope is positioned is taken as a target area. The camera host firstly acquires an image signal of a target area acquired by the camera from the camera of the endoscope, the image signal is corresponding imaging information acquired by the camera receiving an optical signal of the endoscope, and then the image signal is processed by the image processing board card assembly.
And S202, converting and outputting the processed image signals, and recording and storing the output image data to an external storage device, wherein the external storage device is in communication connection with the camera host.
And then, converting and outputting the image signals processed by the image processing board card assembly through the image output board card assembly, and recording and storing the image data output by the image output board card assembly to an external storage device in communication connection with the camera host, wherein the external storage device can be a U disk, and the number of the external storage device can be one or more than one.
Step S203, when a shutdown instruction for controlling the host camera to shut down is received, determining whether the host camera is still in a recording state.
In order to avoid the problem that the camera host is shut down due to misoperation of a user in the process of recording and storing image data output by the image output board card assembly, and further the recorded image data is lost or the external storage device is damaged, the camera host can detect whether a shutdown instruction for controlling the camera host to be shut down is received in the process of recording and storing the image data output by the image output board card assembly, and if the shutdown instruction is detected, whether the camera host is still in a recording state is determined.
In an embodiment, the camera host records and stores the output image data to the external storage device through a video board card, and in order to accurately determine whether the camera host is still in a recording state, the following specific steps may be adopted: determining whether the state identifier of the video board card is a preset state identifier; if the state identifier is not a preset state identifier, determining that the camera host is still in a recording state; and if the state identifier is a preset state identifier, determining that the camera host is not in a recording state.
That is, the camera host can record and store the output image data to the external storage device through the video board card, so that whether the camera host is still in a recording state can be determined by judging the working state of the video board card.
For example, the operating state of the video board card includes an operating state and a closing state, and the operating state of the video board card may be represented by a state identifier, for example, the state identifier "user", "user" true "indicates that the operating state of the video board card is the operating state, and" user "false" indicates that the operating state of the video board card is the closing state. The camera host takes an identifier "user ═ false" when the working state of the video board card is in the off state as a preset state identifier. Therefore, the camera host can acquire the current state identifier of the video board card, and the current working state of the video board card is judged by judging whether the current state identifier of the video board card is the preset state identifier. If the current status identifier of the video board card is not the preset status identifier "user ═ false", the current working state of the video board card can be determined to be the running state, so that the camera host can be determined to be still in the recording state. If the current status identifier of the video board card is the preset status identifier "user ═ false", the current working state of the video board card can be determined to be the off state, so that the camera host can be determined not to be in the recording state.
In an embodiment, in order to accurately determine whether the camera host is still in the recording state, specifically, the following steps may be adopted: determining whether the external storage device is in a data writing state; if the external storage equipment is in a data writing state, determining that the camera host is still in a recording state; and if the external storage equipment is not in a data writing state, determining that the camera host is not in a recording state.
For example, when the camera host is still in the recording state, the external storage device in communication connection with the camera host may still be in the data writing state, and thus, the camera host may determine whether the camera host is still in the recording state by determining whether the external storage device is in the data writing state. If the external storage device is in a data writing state, the camera host can be determined to be still in a recording state; if the external storage device is not in the data writing state, it can be determined that the camera host is not in the recording state.
And step S204, if the camera host is still in the recording state, temporarily not responding to the shutdown instruction, and executing a preset reminding operation to at least remind a user to keep the camera host powered on.
And if the camera host is still in the recording state, temporarily not responding to the shutdown instruction, and executing a preset reminding operation to at least remind a user to keep the camera host powered on. The reminding operation mode can be displaying text reminding information for reminding a user to keep the camera shooting host powered on or broadcasting voice reminding information for reminding the user to keep the camera shooting host powered on. The reminding operation may further include reminding the user to maintain the communication connection between the external storage device and the camera host.
In an embodiment, after the predetermined reminding operation is performed, in order to further ensure the security and integrity of the recorded data, the following steps may be specifically adopted: stopping recording and storing the image data to the external storage device, and responding to the shutdown instruction to close the camera host when determining that the recording and storing of the image data to the external storage device are stopped.
In an embodiment, in consideration that a user feeds back a preset reminding operation, after the preset reminding operation is executed, if a shutdown confirmation instruction fed back by the user based on the reminding operation is obtained, the camera host is forcibly shut down.
That is, if the camera host detects the shutdown instruction again after the reminding operation that at least reminds the user to keep the camera host powered on is executed, it indicates that the user wants to forcibly shut down the camera host, and the camera host forcibly shuts down the camera host.
In an embodiment, after a preset reminding operation is executed, if a closing confirmation instruction fed back by a user based on the reminding operation is not obtained and it is determined that the recording state of the camera host is finished, the camera host is closed by responding to the closing instruction.
That is, in order to further ensure the security and integrity of the recorded video data, if the host camera has not detected a shutdown instruction after performing a reminding operation that at least reminds the user to keep the host camera powered on, the host camera is shut down in response to the detected shutdown instruction when it is determined that the recording state of the host camera is finished.
And step S205, if the camera host is determined not to be in the recording state, responding to the shutdown instruction to close the camera host.
And if the camera host is determined not to be in the recording state, responding to a shutdown instruction to shut down the camera host.
In the video data storage method provided in each of the above embodiments, the camera host acquires an image signal of a target area from the endoscope camera, and processes the image signal; converting and outputting the processed image signals, and recording and storing the output image data to an external storage device, wherein the external storage device is in communication connection with the camera host; when a shutdown instruction for controlling the camera host to be closed is received, determining whether the camera host is still in a recording state; if the camera host is still in the recording state, temporarily not responding to the shutdown instruction, and executing a preset reminding operation to at least remind a user to keep the camera host powered on; and if the camera host is determined not to be in the recording state, responding to the shutdown instruction to close the camera host. Therefore, the mode that the camera host is kept powered on when the camera host is still in the recording state is used for reminding a user, so that the safety and integrity of the video data are ensured, and the damage to the external storage equipment can be avoided.
