Referring to fig. 4, fig. 4 is a flowchart illustrating a video recording method for an endoscope according to an embodiment of the present disclosure. The video recording method is applied to a camera host.

As shown in fig. 4, the video recording method includes steps S101 to S103.

S101, acquiring the equipment state of the external storage equipment connected to the external storage equipment interface.

Specifically, the external storage device connected to the external storage device interface of the camera host is scanned to obtain the device state of the external storage device. The device status includes an available status and an unavailable status, but may also include other information, such as capacity size, remaining capacity, read/write speed, interface type, and so on.

Illustratively, the obtaining of the device state of the external storage device specifically includes: detecting whether an external storage device is accessed; when detecting that an external storage device is accessed, scanning the external storage device to determine whether the external storage device meets the recording requirement; if the external storage equipment meets the recording requirement, determining that the equipment state of the external storage equipment is an available state; and if the external storage equipment does not meet the recording requirement, determining that the equipment state of the external storage equipment is an unavailable state. Therefore, the equipment state information of the external storage equipment can be determined when the equipment is accessed, so that a user can know the equipment state of the external storage equipment before an operation, and the operation and video recording of the user are facilitated.

Specifically, the recording requirement may be a condition for satisfying video recording, and may be set according to a requirement of the video recording on the external storage device. For example, the capacity size must be larger than a preset capacity threshold, the read/write speed must meet the speed requirement, and so on. And determining the equipment state of the external storage equipment which meets the recording requirement as an available state, and determining the equipment state of the external storage equipment which does not meet the recording requirement as an unavailable state.

If at least two external storage devices are detected to be accessed, one of the external storage devices can be scanned first to determine the device state; and scanning the other external storage device to determine the device state of the external storage device. Of course, simultaneous scanning is also possible.

For example, determining whether the external storage device meets the recording requirement may specifically be: identifying the external storage equipment, if the external storage equipment can be identified, determining that the external storage equipment meets the recording requirement, and if the external storage equipment cannot be identified, determining that the external storage equipment does not meet the recording requirement; or determining whether the external storage device has residual storage capacity, if the external storage device has residual storage capacity, determining that the external storage device meets the recording requirement, and if the external storage device has no residual storage capacity, determining that the external storage device does not meet the recording requirement; or determining whether the read-write speed of the external storage device is less than a preset threshold, if the read-write speed of the external storage device is not less than the preset threshold, determining that the external storage device meets the recording requirement, and if the read-write speed of the external storage device is less than the preset threshold, determining that the external storage device does not meet the recording requirement.

Correspondingly, if the external storage device can be identified, the residual storage capacity is sufficient, and the read-write speed meets the requirement, the external storage device is determined to meet the recording requirement. Of course, when determining whether the external storage device meets the recording requirement, the external storage device may include other conditions besides the identification, the remaining storage capacity, and the read-write speed, which are not limited herein.
