Description

Technical Field

[0001] This invention relates to the field of display technology, and specifically to a method, apparatus, and storage medium for adaptive brightness calibration of a medical display. Background Technology

[0002] Medical displays are widely used in medical imaging, lesion observation, clinical diagnosis, and surgical procedures, serving as crucial display terminals in medical equipment systems. Compared to ordinary commercial displays, medical displays have higher requirements for the accuracy, stability, and consistency of image display. The stability of display parameters such as brightness, grayscale, color, and contrast directly affects doctors' ability to discern details in medical images, thereby influencing the accuracy of diagnostic results and the safety of surgical procedures.

[0003] To ensure the display quality of medical monitors, current technologies typically employ either a one-time factory calibration or periodic manual calibration to adjust the monitor's brightness, grayscale, or color parameters. Factory calibration involves setting parameters according to preset standards before the monitor leaves the factory, while periodic manual calibration is performed by maintenance personnel using testing equipment to readjust the display parameters after the equipment has been used for a period of time. While these methods can guarantee the display quality to a certain extent in the initial stage or at specific points in time, their calibration methods are usually based on static conditions and are difficult to adapt to the dynamic changes required in medical settings.

[0004] On the one hand, lighting conditions in medical settings, especially operating rooms, reading rooms, and comprehensive treatment environments, are complex and easily affected by factors such as the on / off state of surgical lights, changes in natural light, and adjustments to indoor lighting, resulting in significant fluctuations in ambient light intensity. Existing monitors using fixed calibration parameters often cannot promptly adjust their brightness to match changes in ambient light, easily causing the displayed image to be too dark or too bright, thus affecting the doctor's ability to observe image details, tissue boundaries, and lesion features.

[0005] On the other hand, medical displays gradually exhibit component aging during long-term use, such as backlight decay, decreased luminous efficiency, and the resulting decrease in brightness and display performance drift. Existing calibration schemes typically cannot detect the aging status of the display in real time, nor can they automatically compensate and adjust according to the degree of aging. As a result, the display effect is prone to gradually deteriorate with the extension of use, which not only affects the display quality of medical images, but also increases the frequency of equipment maintenance and operating costs.

[0006] Furthermore, manual periodic calibration suffers from drawbacks such as cumbersome operation, reliance on human experience, and fixed calibration cycles that are difficult to accurately match actual usage conditions. When the environment changes rapidly or the monitor ages rapidly, manual periodic calibration often fails to respond in time, easily resulting in calibration delays and causing display parameters to deviate from expected standards. Summary of the Invention

[0007] This invention provides a method, apparatus, and storage medium for adaptive brightness calibration of medical displays, which automatically senses, dynamically adjusts, and adaptively compensates for the brightness parameters of medical displays, thereby improving the display stability and reliability of medical displays under different usage environments and long-term operating conditions.

[0008] In a first aspect, the present invention provides a method for adaptive brightness calibration of a medical display, comprising the following steps: Obtain the ambient light intensity parameters of the environment where the medical display is located, as well as the display status parameters of the medical display; When the preset calibration trigger conditions are met, target brightness calibration parameters are generated based on the ambient light intensity parameters and the display status parameters. The target brightness calibration parameters are written into the control unit of the medical display to adjust the display brightness of the medical display; Obtain the display parameters after brightness adjustment, and compare the display parameters after brightness adjustment with the preset display standard; If the comparison results show that the preset display standard is not met, the target brightness calibration parameters are corrected and rewritten to the control unit until the preset display standard is met. Record the calibration data corresponding to this calibration.

[0009] Beneficial effects: This invention provides a method for adaptive brightness calibration of a medical display. It acquires ambient light intensity parameters and display status parameters of the environment in which the medical display is located, and generates target brightness calibration parameters when preset calibration trigger conditions are met. This adjusts the display brightness of the medical display. After brightness adjustment, the display parameters are compared with a preset display standard. If the preset display standard is not met, the target brightness calibration parameters are corrected and rewritten to the control unit until the preset display standard is reached. This allows for adaptive calibration of the medical display brightness based on changes in the external lighting environment and the display's operating status, forming a closed-loop brightness calibration system. This improves the display stability, calibration accuracy, consistency, and reliability of the medical display under different usage environments and long-term operating conditions. Furthermore, by recording calibration data, manual intervention is reduced, increasing the automation and timeliness of calibration, facilitating subsequent traceability, maintenance management, and calibration strategy optimization.

[0010] According to a first aspect of the present invention, generating target brightness calibration parameters based on the ambient light intensity parameters and the display state parameters includes: Based on the ambient light intensity parameters, determine the ambient light adaptive brightness calibration parameters; Based on the display status parameters, determine the aging compensation brightness calibration parameters; The ambient light adaptive brightness calibration parameters and the aging compensation brightness calibration parameters are fused to obtain the target brightness calibration parameters.

[0011] Beneficial effects: By determining the ambient light adaptive brightness calibration parameters based on the ambient light intensity parameters and the aging compensation brightness calibration parameters based on the display status parameters, and then fusing the ambient light adaptive brightness calibration parameters and the aging compensation brightness calibration parameters, the target brightness calibration parameters are obtained. This allows for comprehensive calibration of the display brightness of medical displays by simultaneously considering changes in the external lighting environment and the display's own aging status. This avoids calibration deviations caused by adjusting brightness based on only a single parameter, improves the rationality, adaptability, and brightness calibration accuracy of the target brightness calibration parameters, and ultimately enhances the display stability and reliability of medical displays under complex usage environments and long-term operating conditions.

[0012] According to a first aspect of the present invention, ambient light intensity data is acquired by an ambient light sensor disposed on the inner side of the bezel of a medical display. The ambient light sensor is disposed facing the illuminated area of ​​the medical scene and is used to monitor changes in ambient light intensity in real time.

[0013] Beneficial effects: By collecting ambient light intensity data through an ambient light sensor located inside the bezel of the medical monitor and facing the area illuminated by the medical scene, the changes in lighting conditions in the actual use environment of the medical monitor can be monitored in real time. This improves the real-time performance and accuracy of ambient light intensity data collection, provides reliable data support for subsequent brightness adaptive calibration, and ultimately enhances the medical monitor's responsiveness to changes in external lighting as well as the timeliness and effectiveness of brightness calibration.

[0014] According to a first aspect of the present invention, the display status parameters are acquired by a display brightness sensing module, and the display status parameters include at least one of cumulative usage time, brightness intensity, brightness decay rate, and luminous efficiency.

[0015] Beneficial effects: The display status parameters are collected by the display brightness sensing module. These parameters include at least one of the following: cumulative usage time, brightness intensity, brightness decay rate, and luminous efficiency. This allows the display to characterize the actual operating status of the medical display from aspects such as cumulative usage, current brightness level, and performance decay trend. This improves the accuracy of sensing the display's aging degree and brightness changes, providing more comprehensive data support for subsequent brightness compensation and adaptive calibration. Ultimately, this helps to improve the accuracy of brightness calibration and display reliability of the medical display under long-term operating conditions.

[0016] According to a first aspect of the present invention, determining the ambient light adaptive brightness calibration parameters based on the ambient light intensity parameters includes: The ambient light intensity parameter is compared with a preset light threshold. Increase target brightness when ambient light intensity increases; Reduce target brightness when ambient light intensity decreases; The target brightness is continuously adjusted according to the gradient of changes in ambient light intensity to ensure a smooth transition in display brightness.

[0017] Beneficial effects: By comparing the ambient light intensity parameter with a preset light threshold, and increasing the target brightness when the ambient light intensity increases and decreasing the target brightness when the ambient light intensity decreases, while continuously adjusting the target brightness according to the gradient of changes in ambient light intensity, the display brightness of the medical monitor can be adaptively adjusted according to changes in external light. This reduces the impact of sudden brightness changes on image observation, improves the stability and continuity of the brightness adjustment process, and thus helps to improve the display stability and brightness calibration effect of the medical monitor in complex lighting environments.

[0018] According to a first aspect of the present invention, determining the aging compensation brightness calibration parameters based on the display state parameters includes: Based on a preset aging loss model, the brightness decay is calculated according to the display status parameters. Determine the corresponding brightness compensation value based on the brightness attenuation amount; The compensation coefficient is dynamically adjusted based on the aging trend of the display to generate the aging compensation brightness calibration parameters.

[0019] Beneficial effects: By calculating the brightness decay based on a preset aging loss model and according to the display status parameters, determining the corresponding brightness compensation value based on the brightness decay, and dynamically adjusting the compensation coefficient according to the display aging trend, aging compensation brightness calibration parameters are generated. This allows for adaptive compensation of display brightness based on the actual aging degree and performance change trend of the medical display, reducing compensation deviation caused by fixed compensation methods, improving the accuracy and rationality of brightness compensation, and thus helping to improve the display consistency, stability and reliability of the medical display under long-term operating conditions.

[0020] According to a first aspect of the present invention, the preset calibration trigger condition includes: Real-time triggering conditions when changes in ambient light intensity reach a preset threshold; The timed trigger condition when the cumulative running time of the medical monitor reaches the preset duration.

[0021] Beneficial effects: By setting the preset calibration trigger conditions to real-time trigger conditions when the ambient light intensity changes to a preset threshold and timed trigger conditions when the cumulative running time of the medical monitor reaches a preset duration, brightness calibration can be performed in a timely manner when the external lighting environment changes, and calibration processing can be performed according to a preset cycle during the long-term operation of the medical monitor. This allows the brightness calibration to take into account both real-time response capability and periodic maintenance requirements, reduce display brightness deviation caused by untimely calibration, and thus help improve the automation, timeliness and long-term operational reliability of the brightness calibration of the medical monitor.

[0022] According to a first aspect of the present invention, when the timed triggering condition is met, aging compensation brightness calibration is performed, and ambient light adaptive brightness calibration parameters are optimized simultaneously.

[0023] Beneficial effects: When the timed trigger conditions are met, aging compensation brightness calibration is performed, and ambient light adaptive brightness calibration parameters are optimized at the same time. This can compensate for the aging effects caused by long-term operation of medical displays, while simultaneously adjusting the brightness calibration parameters in combination with the current ambient light conditions. This makes the brightness calibration take into account both the changes in the display's own state and changes in the external usage environment, improving the comprehensiveness, coordination and adaptability of the brightness calibration process. In turn, it helps to improve the display stability and reliability of medical displays under long-term operating conditions and complex lighting environments.

[0024] According to a first aspect of the present invention, the brightness-adjusted display parameters include the adjusted display brightness parameters, and the preset display standard is a preset medical display brightness standard range; When the adjusted display brightness parameter does not fall within the preset medical display brightness standard range, the target brightness calibration parameter is iteratively corrected according to the preset fine-tuning rules.

[0025] Beneficial effects: By comparing the adjusted display brightness parameter with a preset medical display brightness standard range, and iteratively correcting the target brightness calibration parameter according to a preset fine-tuning rule when the adjusted display brightness parameter does not fall within the preset medical display brightness standard range, the results after the initial brightness adjustment can be further verified and continuously optimized. This reduces the impact of one-time adjustment errors on the final display effect, improves the accuracy, stability, and closed-loop control effect of brightness calibration, and ultimately helps to improve the consistency of the display effect and the reliability of medical displays.

[0026] According to a first aspect of the present invention, the calibration data includes: calibration triggering conditions, calibration time, parameters before adjustment, parameters after adjustment, and calibration verification results; The calibration data is archived to form an adaptive calibration profile.

[0027] Beneficial effects: By recording calibration trigger conditions, calibration time, parameters before adjustment, parameters after adjustment, and calibration verification results as calibration data, and archiving this calibration data to form an adaptive calibration archive, data traceability can be achieved for the triggering, execution, and verification process of brightness calibration for medical displays. This improves the traceability and management standardization of the brightness calibration process, facilitates subsequent equipment maintenance, status analysis, and calibration effect verification, and provides data support for subsequent calibration strategy optimization. Ultimately, this enhances the reliability and practicality of brightness calibration management for medical displays.

[0028] Secondly, the present invention also provides a medical display brightness adaptive calibration device, comprising: The sensing module is used to acquire the ambient light intensity parameters of the environment in which the medical display is located, as well as the display status parameters of the medical display. The algorithm module is used to generate target brightness calibration parameters based on the ambient light intensity parameters and the display status parameters when the preset calibration trigger conditions are met. A calibration execution module is used to write the target brightness calibration parameters into the control unit of the medical display in order to adjust the display brightness of the medical display; The verification module is used to acquire the display parameters after brightness adjustment, compare the display parameters after brightness adjustment with the preset display standard, and trigger the correction of the target brightness calibration parameters when the comparison result shows that the preset display standard is not met. The archive module is used to record the calibration data corresponding to this calibration.

[0029] Beneficial effects: By setting up a sensing module, an algorithm module, a calibration execution module, a verification module, and an archiving module, the sensing module acquires the ambient light intensity parameters of the environment where the medical display is located and the display status parameters. The algorithm module generates target brightness calibration parameters when preset calibration trigger conditions are met. The calibration execution module writes the target brightness calibration parameters into the control unit of the medical display to adjust the display brightness. The verification module compares and verifies the display parameters after brightness adjustment and triggers correction of the target brightness calibration parameters if the preset display standard is not met. The archiving module records the calibration data corresponding to this calibration. This enables the coordinated operation of data acquisition, parameter generation, brightness adjustment, result verification, and data archiving in the adaptive brightness calibration process of the medical display, forming a complete closed-loop calibration process. This, in turn, helps to improve the automation level, accuracy, stability, and reliability of the brightness calibration of the medical display.

[0030] According to a second aspect of the present invention, the sensing module includes an ambient light sensor and a display brightness sensing module; The algorithm module is used to determine the ambient light adaptive brightness calibration parameters based on the ambient light intensity data, determine the aging compensation brightness calibration parameters based on the display status parameters, and fuse the ambient light adaptive brightness calibration parameters and the aging compensation brightness calibration parameters to obtain the target brightness calibration parameters.

[0031] Beneficial effects: By incorporating an ambient light sensor and a display brightness sensing module into the sensing module, and having the algorithm module determine ambient light adaptive brightness calibration parameters based on ambient light intensity data and aging compensation brightness calibration parameters based on display status parameters, the target brightness calibration parameters are obtained by fusing the ambient light adaptive brightness calibration parameters and aging compensation brightness calibration parameters. This approach can simultaneously collect information on ambient light changes in the medical display's environment and the display's own operating status, and comprehensively calculate ambient light adaptation and aging compensation. This improves the accuracy, rationality, and adaptability of the target brightness calibration parameters, thereby enhancing the stability, display consistency, and reliability of the medical display's adaptive brightness calibration.

[0032] Thirdly, the present invention also provides a storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, it implements the adaptive brightness calibration method for a medical display as claimed in the claims.

[0033] Beneficial effects: By storing a computer program on a storage medium and enabling the computer program to implement the adaptive calibration method for medical display brightness when executed by a processor, the adaptive calibration function for medical display brightness can be implemented in software. This facilitates the deployment of the method on a corresponding processing platform, improves the flexibility, portability, and ease of application of the solution, and ultimately enhances the practicality and application value of the adaptive calibration solution for medical display brightness.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] It should be noted that the medical display in this embodiment of the invention can be a professional display terminal used for medical image display, lesion observation, surgical navigation, clinical image reading, or other medical scenarios; the display status parameters can include at least one of cumulative usage time, brightness intensity, brightness decay rate, and luminous efficiency; the preset display standard can be a preset medical display brightness standard range, or a system-preset display brightness target range. The control unit can be a control circuit, processor, or control module inside the medical display used to perform brightness parameter writing and display brightness adjustment.

[0038] Example 1 This embodiment provides a method for adaptive brightness calibration of a medical display, referring to... Figure 1 As shown in the flowchart.

[0039] The method described in this embodiment can run on the processor platform built into the medical display or on an external control device that is communicatively connected to the medical display. To implement the method of this embodiment, an ambient light sensor, a display brightness sensing module, a control unit, and software programs for executing calibration algorithms can be pre-configured in the medical display. The ambient light sensor is located inside the bezel of the medical display and faces the illuminated area of ​​the medical scene, used to collect ambient light intensity parameters in the environment in which the medical display is located in real time. The display brightness sensing module is used to collect display status parameters of the medical display to reflect the current operating status and changes in brightness performance of the medical display.

[0040] The method in this embodiment includes the following steps: S101. Obtain the ambient light intensity parameters of the environment where the medical monitor is located, as well as the monitor status parameters of the medical monitor.

[0041] Specifically, the ambient light sensor detects changes in light intensity in the environment where the medical display is used in real time and outputs corresponding ambient light intensity parameters. The display brightness sensing module monitors the current operating status of the medical display and acquires corresponding display status parameters. These parameters may include at least one or more of the following: cumulative usage time, current brightness intensity, brightness decay rate, and luminous efficiency. By simultaneously acquiring ambient light intensity parameters and display status parameters, the external operating environment and internal operating status of the medical display can be characterized, providing a data foundation for subsequent brightness calibration.

[0042] S102. When the preset calibration trigger conditions are met, generate target brightness calibration parameters based on ambient light intensity parameters and display status parameters.

[0043] In this step, the preset calibration trigger conditions can include real-time trigger conditions and timed trigger conditions. The real-time trigger condition can be a change in ambient light intensity reaching a preset threshold; the timed trigger condition can be a cumulative operating time of the medical monitor reaching a preset duration. When the ambient light intensity changes significantly within a short period, the system can trigger real-time calibration; when the medical monitor continues to operate for a preset period, the system can trigger timed calibration, thus balancing timely response to changes in the external environment with periodic maintenance of long-term operating status.

[0044] In one optional implementation, target brightness calibration parameters are generated based on ambient light intensity parameters and display status parameters, with reference to... Figure 2 The flowchart shows the following: Determine the ambient light adaptive brightness calibration parameters based on the ambient light intensity parameters; Determine the aging compensation brightness calibration parameters based on the display status parameters; The ambient light adaptive brightness calibration parameters and the aging compensation brightness calibration parameters are fused to obtain the target brightness calibration parameters.

[0045] Specifically, when determining the ambient light adaptive brightness calibration parameters based on the ambient light intensity parameters, the real-time collected ambient light intensity parameters can be compared with a preset light threshold. (Refer to...) Figure 3 As shown in the flowchart, when the ambient light intensity increases, the target brightness is increased accordingly; when the ambient light intensity decreases, the target brightness is decreased accordingly. Furthermore, the target brightness can be continuously adjusted according to the gradient of changes in ambient light intensity to ensure a smooth transition in display brightness and avoid sudden changes in brightness affecting the continuity and comfort of the doctor's image observation.

[0046] When determining the aging compensation brightness calibration parameters based on the display status parameters, an aging loss model can be established in advance, referring to... Figure 4 As shown in the flowchart, the aging loss model is used to calculate the brightness decay based on the display's state parameters and determine the corresponding brightness compensation value based on the brightness decay. Furthermore, the compensation coefficient can be dynamically adjusted according to the display's aging trend to generate aging compensation brightness calibration parameters that better reflect the actual operating conditions of the medical display. This reduces the problems of insufficient or excessive compensation caused by fixed compensation methods.

[0047] In a preferred embodiment, when fusing the ambient light adaptive brightness calibration parameters and the aging compensation brightness calibration parameters, a comprehensive calculation can be performed according to preset weights, preset priorities, or preset calculation rules to obtain the final target brightness calibration parameters to be written into the control unit. This fusion process allows brightness calibration to simultaneously address both environmental adaptation and aging compensation requirements, avoiding the limitations of adjusting brightness based on only a single parameter.

[0048] S103. Write the target brightness calibration parameters into the control unit of the medical display to adjust the display brightness of the medical display.

[0049] Specifically, after the calibration algorithm generates the target brightness calibration parameters, the control unit receives and executes the corresponding parameter writing operation, thereby driving the medical display to complete the display brightness adjustment. The aforementioned control unit can control the backlight driver, power output, brightness adjustment register, or other brightness control interfaces to ensure that the display brightness is adjusted according to the target brightness calibration parameters.

[0050] S104. Obtain the display parameters after brightness adjustment, and compare the display parameters after brightness adjustment with the preset display standard.

[0051] In this step, the display brightness sensing module can again collect the display parameters after brightness adjustment, which may include at least the adjusted display brightness parameters. Subsequently, the system compares the adjusted display brightness parameters with a preset display standard to determine whether the current calibration result meets the preset requirements. The preset display standard can be a preset medical display brightness standard range or a display brightness target standard set for a specific medical application scenario.

[0052] S105. If the comparison results show that the preset display standard has not been met, the target brightness calibration parameters are corrected and rewritten into the control unit until the preset display standard is met.

[0053] Specifically, when the adjusted display brightness parameters are detected to be outside the preset medical display brightness standard range, the system can iteratively correct the target brightness calibration parameters according to preset fine-tuning rules and rewrite them to the control unit to readjust the display brightness. Afterwards, the system retrieves the adjusted display parameters again and performs a comparison operation, referring to... Figure 5 The flowchart is shown. This method creates a closed-loop calibration mechanism, thereby improving the accuracy and stability of brightness calibration results.

[0054] The preset fine-tuning rules can be set based on the magnitude and direction of the current deviation, historical calibration results, or the most recent calibration correction amount. Through multiple fine-tuning iterations, the display brightness can be gradually brought close to or reach the preset display standard, reducing the impact of a one-time adjustment error on the final calibration result.

[0055] S106. Record the calibration data corresponding to this calibration.

[0056] In this step, the system can record and archive relevant data during the adaptive brightness calibration process. Calibration data may include calibration trigger conditions, calibration time, parameters before adjustment, parameters after adjustment, and calibration verification results. Furthermore, the calibration data can be archived to form an adaptive calibration profile, facilitating subsequent equipment maintenance, status analysis, compliance checks, and calibration strategy optimization.

[0057] In one application scenario, when a medical display is deployed in an operating room, if the operating lights are turned on, causing a significant increase in ambient light intensity, the ambient light sensor detects that the change in ambient light has reached a preset threshold, triggering a real-time calibration process. The system generates ambient light adaptive brightness calibration parameters based on the current ambient light intensity parameters. If it is also detected that the medical display has been running for a long time and its brightness intensity has decreased, then aging compensation brightness calibration parameters are generated by combining the display status parameters, and the target brightness calibration parameters are obtained through fusion processing. After the parameters are written to the control unit, the system then detects the adjusted display brightness and makes fine adjustments as necessary until the display brightness meets the preset standard. This allows the medical display to maintain a relatively stable display effect under the combined effects of changes in external lighting and long-term operation.

[0058] Example 2 This embodiment provides a medical display brightness adaptive calibration device.

[0059] The device can be used in the medical display itself or integrated into a control device that communicates with the medical display. The device includes a sensing module, an algorithm module, a calibration execution module, a verification module, and an archiving module.

[0060] The sensing module is used to acquire ambient light intensity parameters of the environment in which the medical display is located, as well as display status parameters of the medical display. Further, the sensing module may include an ambient light sensor and a display brightness sensing module. The ambient light sensor is disposed inside the bezel of the medical display and faces the illuminated area of ​​the medical scene, and is used to collect ambient light intensity parameters in real time; the display brightness sensing module is used to acquire at least one display status parameter among cumulative usage time, brightness intensity, brightness decay rate, and luminous efficiency.

[0061] The algorithm module generates target brightness calibration parameters based on ambient light intensity parameters and display status parameters when preset calibration trigger conditions are met. Specifically, the algorithm module can determine ambient light adaptive brightness calibration parameters based on ambient light intensity data, determine aging compensation brightness calibration parameters based on display status parameters, and fuse the ambient light adaptive brightness calibration parameters and aging compensation brightness calibration parameters to obtain the target brightness calibration parameters.

[0062] The calibration execution module is used to write the target brightness calibration parameters into the control unit of the medical display in order to adjust the display brightness of the medical display.

[0063] The verification module acquires the display parameters after brightness adjustment and compares them with a preset display standard. If the comparison result shows that the preset display standard is not met, the target brightness calibration parameters are corrected. By setting up the verification module, the device can possess result verification and iterative correction capabilities, thus forming a closed-loop control.

[0064] The archiving module records the calibration data corresponding to this calibration. Calibration data may include calibration trigger conditions, calibration time, parameters before adjustment, parameters after adjustment, and calibration verification results. The archiving module can store this data locally or upload it to an external management platform to create an adaptive calibration archive.

[0065] The device in this embodiment, through the coordinated operation of the sensing module, algorithm module, calibration execution module, verification module, and archiving module, can realize data acquisition, parameter generation, brightness adjustment, verification correction, and data logging in the adaptive brightness calibration process of medical displays, thereby improving the automation, accuracy, and long-term operational reliability of medical display brightness calibration.

[0066] Example 3 This embodiment provides a storage medium on which a computer program is stored. When the computer program is executed by a processor, it implements the adaptive calibration method for medical display brightness of the above embodiment one.

[0067] The storage medium can be a read-only memory, random access memory, flash memory, hard disk, solid-state drive, optical disk, or other tangible storage medium capable of storing computer programs. The computer program can be deployed in a medical display's built-in processor platform, embedded controller, industrial control host, or other devices capable of executing control programs. When the processor executes the computer program, it can sequentially or as needed call functional modules such as acquiring ambient light intensity parameters, acquiring display status parameters, determining preset calibration trigger conditions, generating target brightness calibration parameters, performing brightness adjustment, verifying and correcting results, and recording calibration data to implement the method steps of Embodiment 1 described above.

[0068] In this embodiment, by storing and deploying the medical display brightness adaptive calibration method in the form of a computer program, the flexibility, portability, and ease of application of the solution can be improved. This makes it easier to call, update, and expand the program according to different models of medical displays, different medical scenario requirements, or different calibration strategies.

[0069] It should be noted that the ambient light intensity parameters, display status parameters, target brightness calibration parameters, preset light threshold, preset display standard, preset fine-tuning rules, and aging loss model in the embodiments of the present invention can all be preset or dynamically adjusted according to different medical display models, different application scenarios, and different display requirements. The present invention does not limit these parameters.

[0070] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
