[0053] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.

[0054] In the embodiments of the present disclosure, the term "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0055] The application scenarios described in the embodiments of the present disclosure are used to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those of ordinary skill in the art can know that, as new application scenarios appear, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems. In the description of the present disclosure, unless otherwise specified, the meaning of "multiple" is two or more.

[0056] In the prior art, when the camera host performs linkage control with the cold light source host, the light source adjustment button in the cold light source host can be mistakenly touched, which leads to the situation that the light output in the cold light source host does not match the image demand, so the image quality of the display is reduced.

[0057] Therefore, this disclosure provides a method for controlling a cold light source. When the cold light source host determines that the command sent by the camera host is a dimming command, the cold light source host locks its own dimming button and then emits light based on the command. This avoids the situation where the dimming button in the cold light source host is accidentally pressed, leading to a mismatch between the emitted light and the image requirements. This improves the quality of the displayed image. Furthermore, the button lock state of the cold light source host can be automatically switched, improving usability and the matching between the light source's emission state and the image's emission requirements, which is beneficial for maintaining a good display image effect. The solution of this disclosure will now be described in detail with reference to the accompanying drawings.

[0058] like Figure 5 The diagram shown is a flowchart illustrating the cold light source control method of this disclosure. This method is applied in an endoscope device, which includes a camera host and a cold light source host, and may include the following steps:

[0059] Step 501: The cold light source host acquires the electrical signal between itself and the camera host at specified intervals;

[0060] In this embodiment, the electrical signal is obtained through the communication line between the cold light source host and the camera host. Figure 6 As can be seen, the communication line between the cold light source host and the camera host includes high and low level signal lines, a ground line, and a communication command line. The high and low level signal lines are used to transmit electrical signals between the camera host and the cold light source host. The communication command line is used to transmit instructions between the camera host and the cold light source host. The ground line is used for grounding. In this embodiment, the electrical signals between the camera host and the cold light source host are obtained through the high and low level signal lines.

[0061] Figure 7 This is a structural diagram of the camera unit and the cold light source unit. Figure 7 As can be seen, the camera main unit includes an image processing module, buttons or a touchscreen, and a main unit control module containing software. The cold light source main unit includes a light source control module containing software, a light source driver module, a light source module, and buttons or a touchscreen. The main unit control module containing software in the camera main unit is the module that issues commands. The light source control module containing software in the cold light source main unit is the module that receives commands.

[0062] It should be noted that the specified duration in this application embodiment can be 0.001 seconds, 1 second, 2 seconds, etc. This application embodiment does not limit the specified duration. The specified duration in this application embodiment can be set according to the actual situation.

[0063] In order to ensure that other functions of the cold light source host can be normally used, in an embodiment, if the type of the instruction is a non-dimming instruction type, the cold light source host does not lock the dimming button of itself, and responds to the instruction.

[0064] The non-dimming instruction type corresponds to instructions such as an upgrade cold light source host instruction and a self-check feedback instruction. For example, the camera host upgrades the cold light source host, and in order to confirm it again at the cold light source end, the cold light source host needs to be pressed by the button of the cold light source host itself. At this time, the button in the cold light source host cannot be locked. When there is no display screen in the cold light source host or no fault record display function in the menu, the cold light source host can be used to return the fault record and the self-check result to the camera host, and output on the display for viewing. When the self-check function is used for the connected cold light source host, the button, knob and the like need to be operated. At this time, the camera host image can be used to perform light source self-checking. When the camera host image continues to change and sends a cold light source dimming command, the cold light source automatically switches to the button locking state of linkage.

[0065] Step 502: The cold light source host determines whether it is in a connection state with the camera host according to the acquired electrical signal. If yes, step 503 is performed. If no, step 505 is performed.

[0066] In an embodiment, step 502 can be specifically implemented as: if the electrical signal is a high-level signal, the cold light source host determines that it is in a connection state with the camera host; or if the electrical signal is a low-level signal, the cold light source host determines that it is in an unconnected state with the camera host.

[0067] Step 503: If the cold light source host receives an instruction sent by the camera host, the type of the instruction is determined based on the instruction sent by the camera host.

[0068] The instruction includes the type of the instruction. For example, the form of the instruction can be instruction type + instruction content. The instruction type includes a dimming instruction type and a non-dimming instruction type.

[0069] In order to save computing resources, in an embodiment, before the camera host sends an instruction to the cold light source host, it is necessary to determine whether the linkage control function is started, wherein the linkage control function is used to represent whether the camera host can send a dimming instruction type instruction to the cold light source host. If the camera host determines that the linkage control function is started, the type of the instruction sent to the cold light source host includes a dimming instruction type or a non-dimming instruction type. If the camera host determines that the linkage control function is not started, the type of the instruction sent to the cold light source host includes a non-dimming instruction type.

[0070] In the embodiment of the present application, only when the linkage control function in the camera host is turned on, the camera host can send the dimming instruction type instruction to the cold light source host, otherwise, the camera host can only send the non-dimming instruction type instruction to the cold light source host.

[0071] For example, as shown in FIG. 1, the linkage control function corresponding to the button corresponding to the camera host in the endoscope device, the user can start the linkage control function by opening the linkage control setting corresponding button, Figure 8 Figure 8 Indicates that the linkage control function has been started. At this time, the camera host can control the cold light source host to dim. Figure 9 The linkage control function of the camera host is not started, and at this time the camera host cannot control the cold light source host to dim.

[0072] Step 504: The cold light source host determines that the type of the instruction is a dimming instruction type, and locks the corresponding dimming button in the cold light source host, and emits light based on the instruction;

[0073] When the dimming button in the cold light source host is locked, when the user touches the dimming button, the cold light source host will not respond to the instruction of the dimming button. The dimming button cannot dim at this time.

[0074] Step 505: The cold light source host does not lock the dimming button of the cold light source host.

[0075] In one embodiment, if the linkage control function is not turned on, the corresponding dimming button in the cold light source host is not locked. Thus, the normal use of the cold light source host is ensured.

[0076] When the dimming button in the cold light source host is not locked, when the user touches the dimming button, the cold light source host will respond to the instruction of the dimming button. The dimming button can dim at this time.

[0077] In order to further understand the technical scheme of the present disclosure, the following will be described in detail in combination with Figure 10 The detailed description can include the following steps:

[0078] Step 1001: The cold light source host acquires the electrical signal between the camera host every specified time interval;

[0079] Step 1002: The cold light source host determines whether the electrical signal is a high-level signal, if yes, step 1003 is executed, if not, step 1008 is executed;

[0080] Step 1003: The cold light source host determines that the connection state between the camera host is connected;

[0081] ​Step 1004: The cold light source host judges whether the instruction sent by the camera host is received, if yes, step 1005 is executed, if not, step 1008 is executed.

[0082] Step 1005: The type of the instruction is judged, if it is a dimming instruction type, step 1006 is executed, if not, step 1007 is executed.

[0083] Step 1006: The cold light source host locks the dimming button of itself, and emits light based on the instruction.

[0084] Step 1007: The cold light source host does not lock the dimming button of itself, and responds to the instruction.

[0085] Step 1008: The cold light source host does not lock the dimming button of itself.

[0086] In some possible implementation manners, various aspects of the control method of the cold light source host provided by the present disclosure can also be implemented in the form of a program product, which includes program codes for causing a computer device to execute the steps in the control method of the cold light source host according to various exemplary embodiments of the present disclosure described above in the specification when the program product is run on the computer device.
