The processor also controls the storage of image information acquired during the image capture process in the video file.

The user may take multiple shots on the same day, so the file name of the video file can be set for distinguishing or searching different stored video files. In one embodiment, the processor may determine a camera start time corresponding to the camera start operation, and set a file name of the video file based on the camera start time such that the file name of the video file includes the camera start time. Furthermore, the user can conveniently sort or search different files in the same folder.

Please refer to fig. 7, which is a diagram illustrating a file directory structure according to an embodiment of the present application. If the shooting start time is 2019, 4, 15, and 30 minutes, the processor may set the file name of the video file to include the shooting start time, for example, set the video file to "04151530", where the file name of the video file is "MMDDHHMM" (two months, two days, two hours, and two minutes, respectively). In order to better distinguish different files, a file identifier can be added to the file name of each video file to update the file name of the video file, wherein the file identifier can be letters, numbers or a combination of the letters and the numbers. The file identification of the file name of the video file may be "EF" and the updated video file may be shown as video file 632. In other embodiments, the file identification of the file name of the video file may be "01" and the updated video file may be as shown by video file 614. In this embodiment, the file identifiers of each video file may be different.

In order to better facilitate the user to search for the corresponding files, the files generated in different days can be stored in different storage folders. For example, when the endoscope camera system is turned on (e.g., power is turned on), the processor performs an operation of creating a new storage folder in the memory for storing the file data generated by the current power-on.

In one embodiment, the processor may create a folder within a predetermined file path, such as a storage folder created under a predetermined file path of "ROOT". The processor can traverse the creation time of each storage folder under the preset file path and judge whether the storage folder created on the same day exists or not, and when the storage folder created on the same day does not exist, the processor executes the operation of creating the storage folder so as to create a new storage folder under the preset file path; if the storage folder created on the current day exists, the newly generated file materials can be directly stored in the folder.

In one embodiment, the folder name of the storage folder may be set according to a creation time corresponding to the execution of the operation of creating the storage folder. The processor acquires creation time, and sets the folder name of the storage folder based on the creation time, wherein the creation time comprises one or more of the number of years, the number of months, the number of days, the number of hours and the number of minutes when the corresponding creation folder is operated; alternatively, the creation time includes one or more of the number of years, the number of weeks, the number of days, the number of hours, and the number of minutes corresponding to the time of the operation of creating the storage folder. For example, if the creation time of the created storage folder operation is 15: 10 points in 4/15/2019, the processor may set the folder name 04151510-.

The folder 600 includes one or more storage folders, and a user can determine the creation time according to the folder name of each storage folder. For example, the preset folder 600 includes a first folder 610, a second folder 620 and a third folder 630, where the creation time of the first folder 610 is 30 minutes at 8 o ' clock at 3 month and 15 th at 2019, the creation time of the second folder 620 is 30 minutes at 8 o ' clock at 13 month and 4 month at 2019, and the creation time of the third folder 630 is 30 minutes at 15 o ' clock at 15 month and 4 month at 2019.

Of course, in an embodiment, each video file and its corresponding other file data may be stored in a folder.

In one embodiment, the processor stores the video file in a corresponding storage folder, such as a storage folder created for the current day. For example, video file 612 is stored in a folder 610 created for the current day, video file 622 is stored in a folder 620 created for the current day, and video file 632 is stored in a folder 630 created for the current day.

104, judging whether a screenshot operation for triggering the camera shooting equipment to perform screenshot is acquired in the process of shooting; when the screenshot operation is acquired in the shooting process (for example, the user triggers the screenshot operation by operating a key), step 106 is executed.

And 106, controlling to store the image information corresponding to the triggering moment of the screenshot operation as a screenshot picture.

When the screenshot operation is acquired in the shooting process, the processor can determine the screenshot moment corresponding to the screenshot operation, acquire the image information corresponding to the trigger moment and control the image information corresponding to the trigger moment to be stored as the screenshot picture. For example, if it is determined that the screenshot time is 2019, 4, 15, 30, min and 30 seconds, the processor may obtain the image information corresponding to the screenshot time of 2019, 4, 15, 30, min and 30 seconds, and store the image information at the time as the screenshot picture.

And step 108, setting the file name of the screenshot picture to be associated with the file name of the video file.

When the screenshot operation is acquired simultaneously in the shooting process, in order to facilitate a user to know the correlation between the screenshot picture acquired based on the screenshot operation and the video file acquired based on the shooting operation, the processor determines the screenshot time corresponding to the screenshot operation and acquires the file name of the video file of the image information stored in the shooting process, and the processor 500 further sets the file name of the screenshot picture based on the shooting start time and the file name of the video file so that the file name of the screenshot picture is correlated with the file name of the video file, wherein the correlation between the file name of the screenshot picture and the file name of the video file indicates that the file name of the screenshot picture and the file name of the video file are at least partially the same. As shown in fig. 7, during the image capturing process of storing the image information in the video file 632, the screenshot operation corresponding to the trigger time of 30 minutes 30 seconds at 15 o' clock 4/15/2019 is acquired, and at this time, the processor 500 stores the image information at the trigger time as a screenshot 636 with a file name of "EP-0415153030" (which is respectively expressed as the file identifier, two month number, two days, two hours, two minutes, and two seconds of the video file), where the file name of the screenshot 636 is partially the same as the file name of the video file 632, such as "EP-04151530". Thus, the user can know that the screenshot 636 was generated during the shooting of the video file 632 according to the file names of the video file 632 and the screenshot 636.

In one embodiment, when the camera process is long, the volume of the video file may be large, and therefore, the user may need to take a picture in segments. The user can click a screenshot button in the process of shooting operation, then the processor simultaneously obtains screenshot operation in the process of shooting, controls to stop obtaining image information, and updates the file name of the video file based on the screenshot time, so that the file name of the video file comprises the shooting starting time and the screenshot time. Namely, at least part of screenshot operation in the middle is used as a separation point, and the video recording process is divided into a plurality of video files to be stored. For example, in the second folder 620, when the image capture start operation is acquired at 9 o 'clock, 30 min and 30 sec, 15 o' clock, 4 m/15 m/2019, the processor stores the acquired image information in the video file, and sets the file name of the video file according to the image capture start time corresponding to the image capture start operation, for example, the file name of the video file is "CD-093030-". When a screenshot operation is acquired at 9 o' clock 30 min 40 sec on 15 th day 9 on 4 th month in 2019 during the shooting process, the processor stores image information corresponding to the trigger time as a screenshot picture 624, and sets the file name of the screenshot picture 624 to be associated with the file name of the video file, for example, the file name of the screenshot picture 624 and the file name of the video file both include a label "CD". When the screenshot operation is acquired again at 10 o 10 min 10 s at 15 h 4 in 2019 during the shooting process, the processor may store the image information corresponding to the trigger time as the screenshot 628, store the image information in the two times as one video file, and store the subsequently newly acquired image information as another video file. The processor updates the file name of the video file 622, as shown by the video file 622, based on the trigger time for the screenshot operation. At this time, the file name of the video file 622 includes the shooting start time and the triggering time of the screenshot operation, and the file name of the screenshot 628 is associated with the file name of the video file 622, for example, the file name of the screenshot 624 and the file name of the video file both include "CD" and "101010".

Step 110, judging whether a shooting end operation for triggering the shooting equipment to stop shooting is acquired, and if the shooting end operation is acquired, executing step 112; if the shooting end operation is not acquired and indicates that the shooting process is continued, the method returns to step 102 to continuously store the acquired image information in the video file.

And a step 112 of determining an imaging end time corresponding to the imaging end operation.

Step 114, updating the file name of the video file based on the shooting end time, so that the file name of the video file comprises the shooting start time and the shooting end time. For example, in the first folder 610, when the image capture start operation is acquired at 9 o 'clock, 30 min and 30 sec, 15 o' clock, 3 m/15 m/2019, the processor stores the acquired image information in the video file, and sets the file name of the video file according to the image capture start time corresponding to the image capture start operation, for example, the file name of the video file is "AB-093030-". If the shooting end operation is acquired at 10 o' clock 10 min 10 sec on 3, 15 and 2019, the processor updates the file name of the video file according to the shooting end time, and the file name of the updated video file is shown as the video file 612, namely the file name of the video file comprises the shooting start time and the shooting end time. The video file 614 shows that the imaging start time is 15 o 'clock, 30 min, and 30 sec in 3/15/2019 and the imaging end time is 10 o' clock, 10 min, and 10 sec in 3/16/2019.

For the video file and the image file, they can be distinguished by the type format of the video file and the image file, for example, the type format of the video file includes mp4, avi, flv, etc., and the type format of the screenshot picture may include jpg, png, gif, etc.

In an embodiment, the video file obtained based on the shooting operation and the screenshot picture obtained based on the screenshot operation have different file names, so that the screenshot picture generated in the same shooting process and the video file generated in the shooting process can be stored in the same folder, and a user can rapidly identify the associated screenshot picture and video file.

According to the file storage management method, the file name of the screenshot picture in the shooting operation process is associated with the file name of the stored video file, so that a user can conveniently and quickly obtain the file corresponding to the screenshot operation in the shooting process according to the file name of the screenshot picture and the file name of the video file, and the user can better identify the associated screenshot picture and the associated video file.

Referring to fig. 8, a flowchart illustrating steps of a file storage management method according to another embodiment of the present application is shown. Compared with the file storage management method in the above embodiment, the file storage management method in this embodiment further includes: when step 200 is executed, if the image capture start operation is not acquired, it indicates that the user may trigger the screen capture operation alone, that is, the screen capture operation is not in the image capture process. At this time, step 204 is executed; when the image capturing start operation is acquired, step 202 may be executed, where step 202 is the same as step 102 to step 114 in the above embodiment, and therefore, reference may be specifically made to step 102 to step 114 in the above embodiment.

Step 204, judging whether a screenshot operation for triggering the camera shooting equipment to perform screenshot is acquired; when the screenshot operation is acquired, executing step 206; when the screenshot operation is not acquired, it indicates that the user has not generated the corresponding file by the image capturing operation or the screenshot operation of the endoscope 50, and at this time, the process may be ended.

And step 206, controlling the image information of the triggering moment corresponding to the screenshot operation to be stored as a screenshot picture.

And 208, setting the file name of the screenshot picture to include the trigger moment.

As shown in fig. 7, in an embodiment, for the third subfolder 630, if the screenshot operation is obtained when the trigger time is 15: 30: 20 seconds in 4/15/2019, and the image is not in the process of shooting at this time, the processor may store the image information corresponding to the trigger time as the screenshot picture 634, and set the file name of the screenshot picture 634 to include the trigger time, such as the file name of the screenshot picture 634 being "0415153020-" 2019 "(which is respectively expressed as two month counts, two days, two hours, two minutes, two seconds, and four year counts of the screenshot picture).

The file storage management method provided by the embodiment sets the file name of the screenshot picture according to different rules according to whether the screenshot picture is generated in the shooting process, and is also beneficial for a user to conveniently distinguish different screenshot pictures.

Referring to fig. 9, a flowchart illustrating steps of a file storage management method according to another embodiment of the present application is shown. The file storage management method comprises the following steps:

and step 300, acquiring a video file in the shooting process or acquiring a video file after the shooting is finished.

When a plurality of operations or examinations are performed in the same day, a plurality of video files are generated, and if a user wants to search for the content of a corresponding video file or obtain the content of a video file, the user may need to check each video file in a time-consuming manner, and the video file may include video content with a long duration, so that if the user wants to search for whether the video file includes corresponding target content (such as an image of a specific part of a monitoring object), the user needs to spend a lot of time to search for the target content.

In order to improve the efficiency of searching the target content by the user, in this embodiment, the video file in the shooting process or the video file after the shooting is completed may be sampled to generate one or more sampling pictures, and the file name of each sampling picture is set to be associated with the file name of the corresponding video file.

Step 302, performing sampling processing on the video file based on the sampling time interval to generate one or more sampling pictures.

During the shooting process or after the shooting is completed, the video file can be stored in a memory (including but not limited to a memory inside the endoscope shooting host or an external memory connected to the endoscope shooting host through a communication interface), as shown in fig. 7, the video file 612, the video file 614, and the video file 622 are video files after the shooting is completed; the video file 632 is a video file during image capturing.

The endoscope camera shooting host can sample the video file to obtain each picture during sampling processing, and then a user can judge whether target content exists in the video file according to the pictures obtained through sampling processing.

In an embodiment, one or more sampling time points on the video file may be determined according to the sampling time interval, and video information corresponding to each sampling time point on the video file may be obtained, and specifically, the video information at or near each sampling time point may be controlled to generate a sampling picture corresponding to each sampling time point, where the type format of the sampling picture may include a static file type (e.g., jpg, png) or a dynamic file type (e.g., gif).

In one embodiment, the sampling time interval may be a fixed sampling time interval or a non-fixed sampling time interval, and thus, the sampling time intervals between two adjacent sampling points are the same or different. The processor 500 determines sampling time points on the video file according to the sampling time interval, for example, when the duration of the video file is 30 minutes, if the sampling time interval is a fixed sampling time interval (e.g. 5 minutes), 6 sampling time points are formed on the video file at positions of 5 minutes, 10 minutes … … 25 minutes, and 30 minutes on the duration of the video file. Of course, the sampling time interval may also be a non-fixed sampling time interval. Specifically, the sampling time point may be determined according to a preset sampling rule. For example, the camera host can intelligently recognize the current image information, and when it is recognized that the image changes greatly, for example, it is recognized that the examination part displayed by the image changes, a sampling time point is generated at this time, so as to conveniently record the time when the examination part of the patient changes. Furthermore, after each sampling time point on the video file is determined, the video information of each sampling time point can be obtained, and the obtained video information of each sampling time point can be converted into a sampling picture. The specific conversion process may be performed by corresponding software or commands.

Step 304, setting a file name of each sampling picture to be associated with a file name of the video file, so that the file name of the sampling picture comprises information of a corresponding sampling time point.

When the sampling picture at each sampling time point is obtained, in order to better facilitate the relevance between the sampling picture and the video file for the user, each sampling picture can be set to be correlated with the file name of the corresponding video file, and further, the file name of the sampling picture can also be set to include the information of the corresponding sampling time point, for example, the file name of the sampling picture includes the time position information of the sampling picture in the corresponding video, so that the user can conveniently know the position of the sampling picture in the video.

Referring to fig. 7, after sampling the video file 622, if the sampled picture 626 is obtained, the file name of the sampled picture can be set to include the file name of the video file 622 and the sampling time point of the sampled picture on the video file 622. For example, if the sampling picture is located on the video file 622 at a time point of 1 minute and 1 second, since the file name of the video file 622 is "CD-093030-. In addition, the user can also know the video file corresponding to the sampling picture and the specific position of the video file according to the file name of the sampling picture. For example, if the file name of the sample picture is "CD-093030-.

According to the file storage management method, the video file is sampled according to the sampling time interval, and the sampled picture obtained by sampling is associated with the original video file, so that a user can conveniently determine whether the original video file comprises target content or whether the content which the user is interested in is at a specific time position in the video file according to the sampled picture.

Referring to fig. 10, a flowchart illustrating a file storage management method according to another embodiment of the present application is shown. The file storage management method comprises the following steps:

when a user needs to search whether a video file includes a target content (e.g., an image of a specific portion of a monitoring object), the user may need to check each video file from beginning to end in a time-consuming manner, and the user needs to spend a lot of time for searching, which brings inconvenience to the user.

In order to improve the efficiency of searching for the target content by the user, in this embodiment, the video file in the shooting process or the video file after the shooting is completed is obtained and indexed to generate one or more pieces of index information, so that the user can judge whether the video file is the target content to be searched or whether the target content of interest is located at which position of the video file according to the index information included in the video file, which is beneficial to improving the efficiency of searching for the target content by the user.

And step 400, storing the image information acquired in the shooting process in a video file.

In this embodiment, steps 100 to 114 in the above embodiments may be executed to store the image information transmitted in the shooting process in the video file, which may be referred to as steps in the above embodiments.

Step 402, judging whether an index operation triggering the establishment of an index for the video file is acquired in the shooting process; when the index operation is acquired in the image pickup process, executing step 406; when the index operation is not acquired during image capturing, step 404 is executed.

In this embodiment, the index operation may be triggered in the shooting process, and if the screenshot operation is acquired in the shooting process, that is, when the acquired screenshot operation is acquired, it is determined that the index operation that triggers the index establishment for the video file in the shooting process is acquired.

Step 404, judging whether an index operation triggering the index establishment of the video file is acquired after the shooting is finished; when the index operation is acquired after the shooting is completed, executing step 406; otherwise, the process ends.

In this embodiment, the indexing operation may be triggered after the image capture is completed, for example, the indexing operation is performed on the video file 622, and in this case, the indexing operation includes sampling processing performed on the video file based on the sampling time interval. In other embodiments, the sampling process may also be performed based on the sampling time interval when indexing the video file during the image capturing process.

Step 406, performing index processing on the video file based on the index operation, so that the video file includes index information corresponding to the index operation. Specifically, the index information may be used to be displayed in a playing interface when the video file is played.

In this embodiment, the index time corresponding to the triggering of the index operation is determined, and the index processing is performed on the video file based on the index time, so that the index information of the video file includes the index time.

When screenshot operation is acquired in the shooting process, indexing operation is carried out on the video file stored in the shooting process according to the screenshot operation, and the screenshot time corresponding to the acquired screenshot operation can be used as the indexing time.

After sampling processing of the video file based on the sampling time interval is acquired after shooting is completed, one or more sampling time points of the sampling processing on the video file can be determined, and the index time is determined to include the corresponding sampling time point.

Likewise, the sampling instant spacing may be a fixed sampling instant spacing or a non-fixed sampling instant spacing.

Step 408, playing the video file including the index information. Specifically, the video file can be played directly through the camera host and displayed on a display connected with the camera host; or the user copies the video file to another playing device (such as a computer) for playing.

Please refer to fig. 11, which is a schematic diagram illustrating playing of a video file according to an embodiment of the present application. When a video file including index information is played, the video content of the video file may be displayed within the display screen 508, where the display screen 508 includes an image display area 580, a time control area 584, and an index display area 582, where the index display area 582 displays one or more index pictures 528 of the index information.

In this embodiment, when playing a video file including index information, the camera host may perform preprocessing on the video file, such as determining an index picture corresponding to each index time, and displaying each index picture 528 in the index display area 582 in a tiled manner during playing.

For example, the camera host can control the index picture to be displayed at the position corresponding to the index time on the video file. In this embodiment, the index pictures 528 include a first index picture, a second index picture, a third index picture, and a fourth index picture, where the first index picture and the third index picture may be generated according to a screenshot operation acquired in a shooting process, and the second index picture and the fourth index picture may be generated based on a sampling time interval. When the index picture 528 is clicked or selected, the user can quickly play the video content at the index time at which the index picture 528 is located.

When the file storage management method is used for playing the video file comprising the index information, a user can conveniently and quickly position the content to be watched according to the position of the index information, and the efficiency of searching the target content by the user is further improved.
