At present, the mainstream medical endoscope generally adopts an LED long-bright light supplementing scheme. Although this scheme can provide a continuous light source, it has the following two defects, which seriously affect the safety of clinical use and the imaging quality: 1) Thermal safety risk is prominent: under the traditional LED long-bright light supplementing state, electrical energy is continuously converted into heat energy, resulting in a temperature rise of ≥15℃ at the front end of the endoscope, which easily causes mucosal burns, especially in long-time surgery (such as complex colonoscopy), the risk of burns is significantly increased, which violates the requirement of IEC 60601-1 medical electrical equipment safety general standard for temperature rise of human body contact part.

[0003] 2) Image disorder problem frequently occurs: the traditional LED long-bright light supplementing does not match the line-by-line exposure timing of the image sensor. The problem is particularly obvious in two typical clinical scenarios: one is when the endoscope moves quickly, the line-by-line exposure under the long-bright light source easily produces image tearing and striping problems; the other is in the intracavity bleeding scene, the blood reflection and the long-bright light source are superimposed, resulting in local overexposure, and due to the continuous effect of the light source in the exposure period, image flicker and image disorder problems easily occur, which seriously affects the accuracy of the doctor's judgment of the lesion.

[0004] In addition, although some existing technologies attempt to use pulse LED light supplementing to reduce power consumption, the light supplementing timing and the image sensor exposure timing are not precisely synchronized, resulting in uneven image brightness, tearing or local overexposure in dynamic scenes, and the temperature rise control problem has not been systematically solved, which still cannot meet the strict requirements of IEC 60601-1 standard on temperature rise.

DETAILED DESCRIPTION

[0019] In order to make the technical problems, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0020] It is to be understood that the terms "including", "containing", "having" and variations thereof herein are intended to be open-ended terms that specifically mean the presence of the stated features, integers, steps, actions, processes, operations, components, members, elements or the like, but do not exclude the presence or addition of one or more other features, integers, steps, actions, processes, operations, components, members, elements or the like.

[0021] As shown in Figure 1 An embodiment of the present application provides an endoscope pulse light supplement imaging method, comprising the following steps: Step S1, initialization and vertical blanking: driving the image sensor of the camera into the LED mode, performing the vertical blanking operation, completing the pixel reset and parameter initialization, to clear the historical residual, ensure that each image acquisition is carried out in a new and stable initial state, avoid the interference of historical data on the current imaging, and ensure the accuracy and consistency of image acquisition.

[0022] Step S2, exposure and pulse light supplement synchronization: triggering the image sensor to perform the exposure stage, and controlling the image sensor to output the pulse signal synchronized with the exposure to the LED light supplement lamp, to realize the synchronization of light supplement and exposure; the LED light supplement lamp only works in the exposure period, compared with long-bright light supplement, greatly reduces the time of converting electric energy into heat energy, effectively reduces the temperature rise of the front end of the endoscope lens, avoids the risk of mucosa burn, and meets the requirements of IEC 60601-1 medical electrical equipment safety general standard on the temperature rise of human body contact parts. In the exposure stage, the image sensor controls the pixel array to collect the light signal, and converts the collected light signal into pixel accumulated charge, to provide the original photoelectric signal basis for generating clear digital images subsequently.

[0023] Step S3, gating control and data output: after the exposure ends, the gating request is received and the gating pulse is generated, to orderly control the image sensor to perform data output, and ensure the synchronization and orderliness of digital image data transmission. When the image sensor performs data output, the pixel accumulated charge after the exposure is converted into digital image data, and is outputted according to the working time sequence, so that the rear-end device can timely and accurately acquire the image information, to provide clear image basis for the doctor to observe and judge the lesion.

[0024] In an embodiment, according to the system time sequence requirement, a virtual line can be inserted in the data output time sequence, to adjust the output rhythm of the image sensor, to flexibly adapt to the requirements of different systems on time sequence and data format, enhance the universality and compatibility of the method, and facilitate the connection with various rear-end processing chips and other devices.

[0025] Step S4, light compensation and imaging in cycle: according to the working timing, repeating steps S1-S3, realizing the light compensation and imaging of continuous frames, ensuring that the endoscope can continuously and stably provide clear images during the working process, meeting the demand for dynamic images in clinical examination and surgery scenes, and providing support for the continuous observation and operation of doctors.

[0026] The endoscope pulse light compensation imaging method of the embodiment can control the temperature rise of the front end of the endoscope lens to ≤15℃ by changing the traditional LED long-light compensation to pulse light compensation and precisely synchronizing with the exposure timing of the image sensor, so as to meet the IEC60601-1 medical electrical equipment safety general standard, greatly optimize the image quality, significantly reduce the light compensation power consumption, effectively solve the problems of prominent heat safety risk and image disorder in the prior art, ensure the imaging clarity, improve the safety of clinical use, and enable the endoscope to stably and safely work in long-time surgery scenes, thereby providing more reliable imaging support for doctors to accurately judge the lesion.

[0027] As shown in FIG. 1, Figure 2 An embodiment of the present application provides an endoscope pulse light compensation imaging device, which comprises a camera 1 and an LED light compensation lamp 2. The camera 1 is arranged at the front end of the endoscope lens, and the camera 1 comprises an image sensor 101 and a lens 102. The image sensor 101 works in an LED mode and outputs a pulse signal synchronized with exposure. The image sensor 101 is internally provided with a signal processing unit, and the signal processing unit can execute the endoscope pulse light compensation imaging method of the above-mentioned embodiment. The LED light compensation lamp 2 is arranged at the front end of the endoscope lens and located at one side of the lens 102. The LED light compensation lamp 2 receives and performs pulse light compensation according to the pulse signal.

[0028] The endoscope pulse light compensation imaging device provided by the embodiment of the present application can execute the above-mentioned method embodiment, and the implementation principle and technical effects are similar, which will not be described here.

[0029] Figure 3 FIG. 2 is a working timing diagram of the image sensor 101 entering the LED mode. The working principle of the image sensor 101 entering the LED mode from the timing signal coordination angle is as follows: 1) vertical blanking: the image sensor 101 first enters the vertical blanking stage, which prepares for image acquisition. The image sensor 101 will complete pixel reset and parameter initialization and other operations, restore each pixel to the initial zero charge state, completely remove the charge signal of the historical residual of the previous frame image, and avoid the interference of the history residual on the current frame image acquisition. The blocks and rectangles corresponding to “vertical blanking” in the figure show the blanking periods at different times. The blanking period can be adjusted according to the specific imaging demand and system configuration to adapt to different imaging scenes.

[0030] 2) Exposure time: After entering the exposure stage, the image sensor 101 controls its pixel array to collect light signals and convert the collected light signals into pixel accumulated charges, similar to the camera shutter opening to let the film be exposed. The oblique fill area of "exposure time" in the figure represents the period during which the pixel array actually collects light signals and converts them into pixel accumulated charges. After passing through the lens 102, the light enters the image sensor 101, and the pixel array of the image sensor 101 accumulates charges during this period, corresponding to the photoelectric conversion and original signal acquisition stage of the image. The "correctly exposed frame" mark in the figure clearly indicates the effective exposure image frame obtained after this stage, ensuring the effectiveness of imaging.

[0031] 3) Data out: After exposure, the image sensor 101 outputs digital image data converted from pixel accumulated charges in a time sequence. In the figure, the blank square of "data out" represents the normal effective image data output period, which includes the brightness and color information of each row of pixels. The gray square represents special data (or meaningless filling) generated by inserting dummy lines, etc. (for timing matching, meeting interface transmission requirements, etc.). Since the number of inserted dummy lines is configurable, it can adapt to the needs of different systems for timing, data format, such as matching the input requirements of the back-end processing chip, or adjusting the frame rate, etc.

[0032] 4) Strobe request: The strobe request is a trigger signal initiated by external devices (such as back-end image processors) or internal modules of the image sensor 101 to request data, which is used to inform the image sensor 101 to prepare for the data output stage. The "start" mark of "strobe request" in the figure represents the trigger starting point, which is used to clearly indicate the time when the strobe request starts to take effect.

[0033] 5) Strobe pulse: After responding to the strobe request, a strobe pulse is generated to control the data output timing, ensuring synchronous and orderly data transmission. If necessary, the output rhythm can be adjusted by programming control through "inserted dummy lines" to flexibly adapt to the timing requirements of the system. The "request here" mark of "strobe pulse" in the figure represents the request effective area, which triggers the subsequent strobe pulse in this area, ensuring the timeliness and accuracy of the strobe pulse generation, and thus ensuring the stability of data transmission.

[0034] In an embodiment, the pulse frequency of the pulse signal output by the image sensor 101 is 20-60 Hz. The 20-60 Hz pulse frequency range can well match the exposure timing of the image sensor 101, so that the pulse light compensation of the LED light compensation lamp 2 is accurately synchronized with the exposure of the image sensor 101. It can not only ensure sufficient light compensation times per unit time to meet the imaging light demand, but also prevent excessive heating of the LED light compensation lamp 2 due to high frequency, thereby ensuring imaging quality while controlling the temperature rise at the front end of the endoscope lens and reducing the thermal safety risk.

[0035] In an embodiment, the pulse current of the pulse signal output by the image sensor 101 is 50-200 mA, and the pulse width of the pulse signal output by the image sensor 101 is 0.06-30 mA. The pulse current in the range of 50-200 mA can provide appropriate driving current for the LED light compensation lamp 2, ensuring that the brightness during light compensation is sufficient for the image sensor 101 to collect clear light signals. The pulse width in the range of 0.06-30 mA not only ensures the amount of light required for exposure, but also shortens the working time of the LED light compensation lamp 2, reduces the amount of electrical energy converted into heat energy, further reduces the temperature rise at the front end of the lens, and effectively reduces the image disorder problem that may be caused by long light compensation.

[0036] In an embodiment, the LED light compensation lamp 2 is a white light LED lamp. The white light LED lamp can provide illumination close to natural light, and can truly restore the color information of the intracavity tissue, so that the doctor can more accurately judge the color characteristics of the lesion, such as the color difference between the diseased tissue and the normal tissue, when observing the image, thereby improving the accuracy of lesion judgment and providing a more reliable visual basis for clinical diagnosis. Of course, in other embodiments, the LED light compensation lamp 2 can also use non-white light LED lamps (such as RGB LED lamps) to realize various color transformations by combining with a white balance algorithm, so as to adapt to more diversified diagnosis and treatment needs.

[0037] In an embodiment, the LED light compensation lamp 2 can also use an external light source, such as a fiber-optic light source. In a reusable endoscope (a gastroscope or a colonoscope that can be repeatedly sterilized), an external light source is transmitted to the front end of the endoscope lens by a fiber-optic light source and located on one side of the lens 102, thereby realizing the light compensation function.

[0038] In an embodiment, the image sensor 101 is an OV5640 COMS image sensor or an OV9734 COMS image sensor. Both the OV5640 COMS image sensor and the OV9734 COMS image sensor have good imaging performance, such as high resolution and good low-light imaging capability. With the cooperation of the pulse light supplement, the light signal can be efficiently collected and converted into clear digital image data, providing hardware support for subsequent clear presentation and accurate diagnosis of images, and ensuring the imaging quality. Of course, in other embodiments, the image sensor 101 can also use other types of image sensors, and the present application does not limit this.

[0039] In a specific embodiment, the endoscope pulse light supplement imaging device is applied to a 5.2mm bronchoscope, the image sensor 101 is an OV9734 COMS image sensor, the LED light supplement lamp 2 is a white light LED lamp, the pulse frequency of the pulse signal output by the image sensor 101 is 20-60Hz, the pulse current of the pulse signal output by the image sensor 101 is 120mA, and the pulse width of the pulse signal output by the image sensor 101 is 0.5ms. The endoscope pulse light supplement imaging device with the above settings can achieve the following effects when the 5.2mm bronchoscope is actually measured: 1) thermal safety: the maximum temperature rise of the front end of the bronchoscope is 10.6℃, which is much lower than the limit of 15℃, meets the IEC 60601-1 medical electrical equipment safety general standard, effectively avoids the risk of mucosal burn caused by excessive temperature rise, significantly improves the safety of clinical use, and is especially suitable for long-time bronchial examination and other surgical scenarios; 2) image quality: the image has no visible flicker, and the subjective score of picture disorder is improved by ≥2 points, indicating that the device effectively solves the image tearing, striping, flickering and other disorder problems caused by traditional long-bright light supplement, makes the image more stable and clear, and can help doctors more accurately observe the situation inside the bronchus and judge the lesion; 3) power consumption: the average power consumption of the LED is ≤200mW, which realizes low power consumption on the premise of ensuring imaging quality and thermal safety. Low power consumption not only helps to prolong the working time of the endoscope, but also further reduces the total amount of electrical energy converted into heat energy, which indirectly helps to control the temperature rise of the front end of the endoscope.

[0040] In a specific embodiment, the endoscope pulse light supplement imaging device is applied to a 13mm colonoscope, the image sensor 101 is an OV5640 COMS image sensor, the LED light supplement lamp 2 is a white light LED lamp, the pulse frequency of the pulse signal output by the image sensor 101 is 20-60Hz, the pulse current of the pulse signal output by the image sensor 101 is 150mA, and the pulse width of the pulse signal output by the image sensor 101 is 0.06ms. Through actual measurement, the temperature at the front end of the colonoscope is 10.6℃, and the image disorder probability is reduced from 15% to 0.2%. Thermal safety: temperature rise ≤15℃, meeting IEC 60601-1; image quality: subjective score of picture disorder is improved by ≥2 points; power consumption: average power consumption of LED ≤200mW. The endoscope pulse light supplement imaging device with the above settings can achieve the following effects in a 132mm colonoscope through actual measurement: 1) thermal safety: the maximum temperature at the front end of the colonoscope is 12.6℃, which is lower than the limit value of 15℃, meeting the IEC 60601-1 medical electrical equipment safety general standard, effectively avoiding the risk of mucosa burn caused by excessive temperature rise, and significantly improving the safety of clinical use, especially suitable for long-time bronchoscopy and other surgical scenarios; 2) image quality: the image disorder probability is reduced from 15% to 0.2%, and the subjective score of picture disorder is improved by ≥2 points, greatly improving the image quality, reducing the interference of image disorder on the doctor's judgment of lesions, and improving the accuracy of diagnosis, especially in scenarios such as intracavity bleeding that are prone to image disorder, the advantage is more obvious; 3) power consumption: average power consumption of LED ≤200mW, on the premise of ensuring imaging quality and thermal safety, low power consumption is realized, which is not only beneficial to prolong the working time of the endoscope, but also further reduces the total amount of electrical energy converted into heat energy, which indirectly assists in controlling the temperature rise at the front end of the scope.
