Description

Technical Field

[0001] The present application relates to the technical field of backlight dimming, and in particular to a backlight zone dimming method and system for a display. Background Art

[0002] The light source of traditional CRT TV is a flat light source, which cannot realize dimming by area according to the picture. With the rise of LCD TV, the backlight brightness area adjustment technology has developed rapidly, from 0-dimensional, 1-dimensional to the current 2-dimensional, that is, the partition backlight technology. The display part of LCD TV mainly includes backlight and liquid crystal display unit, among which the backlight mainly adopts linear light source CCFL and point light source LED. LED is small in size and belongs to point light source, which makes it possible to realize true regional dimming technology. The core of the partition backlight technology is to divide the traditional single backlight into multiple independent areas, each of which can adjust the brightness independently according to the content of the picture. When the display screen needs higher brightness, the TV will increase the LED brightness of the area that needs brighter and reduce the LED brightness of the area that needs darker, so as to realize the control of regional brightness. However, in the medical industry, medical displays are used to display images such as high-definition surgical images, X-rays, CT scans, etc. that capture the specific conditions of the human body. In order to enable medical staff to judge the patient's condition more accurately, the requirements for backlight partition dimming are very high.

[0003] In related technologies, the number of backlight partitions has a direct impact on image quality. A smaller number will have limited effect, while a higher density will require greater technical complexity. The backlight areas divided in the currently used backlight partition dimming method are not sufficient to support rigorous image display in medical scenarios, and the dimming effect is poor. Summary of the invention

[0004] The present application provides a display backlight zone dimming method and system to solve the above-mentioned problems.

[0005] In a first aspect, the present application provides a backlight zone dimming method for a display, comprising:

[0006] Acquire a medical image to be displayed, and determine the medical image type of the medical image to be displayed;

[0007] Determine the backlight working area corresponding to the backlight substrate on the medical display according to the type of medical image, and determine the corresponding target backlight lamp beads according to the backlight working area;

[0008] According to the backlight working area, medical image type and preset step brightness, the dimming mode corresponding to the target backlight lamp beads is determined, and the target backlight lamp beads are adjusted according to the dimming mode.

[0009] Through the above technical solution, by first acquiring the medical image to be displayed and determining its type, the backlight can be more accurately zoned and dimmed according to the characteristics of different medical images. This helps to enhance the contrast, brightness and clarity of the image, thereby improving the medical staff's ability to recognize the details of the medical image, which is of great significance for the accurate diagnosis of the disease. Determining the working area on the backlight substrate according to the type of medical image, and selecting the target backlight lamp beads for dimming accordingly can avoid unnecessary backlight waste. This localized and precise backlight management can significantly improve the energy efficiency of the display, extend the service life of the display, and reduce energy consumption. Different types of medical images may require different display conditions to maximize their readability and visual effects. This application dynamically adjusts the brightness of the backlight lamp beads to ensure that any type of medical image can be presented in the best state, thereby enhancing the image observation experience and diagnostic efficiency of medical staff.

[0010] Optionally, obtaining a medical image to be displayed and determining a medical image type of the medical image to be displayed includes:

[0011] Acquiring medical images to be displayed;

[0012] Performing image analysis on the medical image to be displayed to determine the corresponding image content, relevant human body parts, and display attributes of the relevant human body parts;

[0013] Determine the corresponding medical image type based on the image content, related human body parts, and display attributes.

[0014] Through the above technical solution, by performing detailed image analysis on the medical images to be displayed, the image content, related human body parts and the display properties of these parts can be accurately determined. This precise analysis capability can correctly classify medical images into different types, providing an accurate basis for subsequent processing and display. After determining the type and specific characteristics of the medical image, targeted display optimization can be performed based on this information. For example, for X-rays containing complex bone structures, the display parameters can be adjusted to enhance the visibility of the bones; for MRI images that need to observe soft tissue details, the contrast and brightness settings can be optimized. This display optimization based on image type can significantly improve the clarity and readability of the image, thereby helping doctors interpret image information more accurately.

[0015] Optionally, according to the type of medical image, determining a backlight working area corresponding to a backlight substrate on a medical display, so as to determine a corresponding target backlight lamp bead according to the backlight working area, includes:

[0016] Determine display requirements based on the type of medical image;

[0017] According to the medical image type and display requirements, the corresponding backlight working area is determined, and the target backlight lamp beads are determined according to the backlight working area.

[0018] Through the above technical solution, by determining the display requirements according to the type of medical image and accurately dividing the backlight working area accordingly, it is possible to ensure that the backlight beads on the medical display work in the most suitable way, thereby significantly improving the contrast, brightness and color reproduction of the image. This is crucial for medical staff to accurately interpret medical images and discover detailed information, which helps to improve the accuracy and efficiency of diagnosis. By precisely controlling the backlight working area, unnecessary backlight waste is avoided. Different medical image types may require different display effects to highlight key information. By adjusting the backlight working area according to the type of medical image and display requirements, a more comfortable and intuitive visual experience can be provided for medical staff. When viewing medical images, medical staff can find key information faster, reduce visual fatigue, and improve job satisfaction.

[0019] Optionally, the above method further includes:

[0020] According to the part characteristics of the human body part, determine the structures and association relationships of multiple human body sub-parts in the corresponding human body part;

[0021] Generate step brightness based on the structures and associations of multiple human body sub-parts and the preset backlight bead settings.

[0022] Through the above technical solution, by deeply analyzing the part characteristics of human body parts, the structure and correlation of multiple human body sub-parts can be accurately identified and presented. It helps to more realistically reflect the anatomical structure and spatial layout of human body parts in backlight display, and provide more accurate and intuitive visual information for medical teaching, rehabilitation training, virtual reality and other fields. According to the structure and correlation of multiple human body sub-parts, and the preset backlight lamp bead setting method, a stepped brightness effect can be generated. This brightness difference not only enhances the layering of the image, but also makes different human body parts more visually distinct.

[0023] Optionally, step brightness is generated according to the structures and associations of multiple human body sub-parts and a preset backlight bead setting method, including:

[0024] Obtaining light characteristics of human body parts;

[0025] Set the basic brightness according to the light characteristics and the working environment information of the medical display;

[0026] Generate step brightness based on the structure, association, backlight bead setting method and basic brightness.

[0027] Through the above technical solution, by accurately obtaining the light characteristics of human body parts and adjusting the brightness of the backlight beads accordingly, the display effect of medical images can be significantly improved. Different parts such as bones, muscles, and blood vessels have different absorption and reflection characteristics of light, and can present a clearer and three-dimensional visual effect under backlight adjustment. Setting the basic brightness according to the working environment information of the medical display, and generating stepped brightness based on the structure and correlation of human body parts on this basis can effectively avoid the problem of overexposure or darkening of the image, make the brightness distribution more reasonable, and improve the overall quality of the image. The generation of stepped brightness allows different parts of the human body to form a visual contrast between light and dark, enhances the layering of the image, helps to more clearly identify and understand the detailed information in the image, and improves the accuracy and efficiency of diagnosis.

[0028] Optionally, according to the backlight working area, the medical image type and the preset step brightness, the dimming mode corresponding to the target backlight lamp bead is determined to adjust the target backlight lamp bead according to the dimming mode, including:

[0029] According to the medical image type and step brightness, determine multiple brightnesses corresponding to the target backlight beads;

[0030] Determine how multiple brightness levels vary based on the backlight working area and the type of medical image;

[0031] A plurality of brightness and change modes are determined as dimming modes, so as to adjust the target backlight lamp beads according to the dimming modes.

[0032] Through the above technical solution, by determining multiple appropriate brightness levels for the target backlight beads according to the medical image type and the preset step brightness, the display effect of the medical image can be significantly improved. Different image types have different requirements for brightness and contrast due to their different imaging principles and information presentation methods. The present application can accurately dim the image for different image types, making the details in the image clearer and the structure more distinct, thereby improving the diagnostic accuracy of medical staff. According to the backlight working area and the medical image type, multiple brightness change methods, such as change speed, duration, etc., are determined to further enhance the layering of the image.

[0033] Optionally, according to the type of medical image, determining a backlight working area corresponding to a backlight substrate on a medical display, so as to determine a corresponding target backlight lamp bead according to the backlight working area, includes:

[0035] Detect the working status of multiple optional backlight lamp beads in the backlight working area;

[0036] In the case that any optional backlight lamp bead is a damaged lamp bead, a replaceable lamp bead is determined based on the lamp bead properties of the damaged lamp bead, so as to determine the target backlight lamp bead based on multiple optional backlight lamp beads and replaceable lamp beads; wherein the damaged lamp bead is an optional backlight lamp bead whose working state is abnormal.

[0037] Through the above technical solution, by determining the backlight working area according to the type of medical image, it is possible to ensure that the backlight light accurately illuminates the key areas in the image, thereby optimizing the brightness, contrast and clarity of the image. When the lamp beads in the backlight working area are detected to be damaged, it is possible to quickly identify and find replaceable lamp beads for replacement. This not only avoids the decline in the overall backlight effect due to the damage of a single lamp bead, but also significantly extends the service life of the backlight system and reduces the cost of maintenance and replacement.

[0038] Optionally, in the case where any optional backlight lamp bead is a damaged lamp bead, a replaceable lamp bead is determined according to the lamp bead properties of the damaged lamp bead, so as to determine the target backlight lamp bead according to the plurality of optional backlight lamp beads and replaceable lamp beads, including:

[0039] In the case that any optional backlight lamp bead is a damaged lamp bead, obtaining the lamp bead properties of the damaged lamp bead;

[0040] Determine the position information of the damaged lamp bead on the backlight substrate and the distance between the damaged lamp bead and the optional backlight lamp bead from the lamp bead properties;

[0041] Determine the location range of replaceable lamp beads based on location information and distance;

[0042] The optional backlight lamp beads within the replaceable lamp bead position range are determined as replaceable lamp beads;

[0043] Determine the target backlight lamp beads based on multiple optional backlight lamp beads and replaceable lamp beads.

[0044] Through the above technical solution, when a certain lamp bead in the backlight system is damaged, the damaged lamp bead can be quickly identified and located, and then a replaceable lamp bead can be found within a suitable position range based on its lamp bead properties. This not only avoids the overall backlight effect degradation caused by the damage of a single lamp bead, but also significantly improves the stability and reliability of the backlight system. By accurately matching the lamp bead properties of the damaged lamp bead, the closest replaceable lamp bead can be found, thereby ensuring that the backlight effect after replacement is as consistent as possible with the original effect. This helps maintain the high quality and clarity of medical images and provides accurate diagnosis basis for medical staff.

[0045] Optionally, the target backlight lamp beads are determined based on a plurality of optional backlight lamp beads and replaceable lamp beads, including:

[0046] Obtaining the positional relationship between normally operating lamp beads and replaceable lamp beads; wherein the normally operating lamp beads are a plurality of optional backlight lamp beads other than the damaged lamp beads;

[0047] Determine the impact information on the overall backlight effect based on the position relationship;

[0048] According to the impact information, target replacement lamp beads are determined from replaceable lamp beads, so as to determine the normally operating lamp beads and the target replacement lamp beads as the target backlight lamp beads.

[0049] Through the above technical solution, by considering the position of each replaceable lamp bead and its potential impact on the backlight effect, the present application can ensure that the selected target replacement lamp bead can maintain the original performance of the medical display to the greatest extent after replacement. By accurately matching the position and properties of the normally operating lamp bead with the replaceable lamp bead, the uneven backlighting caused by the damage of a single lamp bead is effectively reduced, and the overall visual effect of the display is improved.

[0090] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0091] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0092] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0093] If the number of backlight zones on the backlight board is small, the display quality after dimming is poor. If the number of backlight zones on the backlight board is large, it is difficult to perform comprehensive and detailed zone dimming, resulting in unsatisfactory final display effect. At present, in order to reduce the difficulty of dimming, the number of backlight zones obtained by backlight partitioning is suitable for most display scenarios, but for medical scenarios that require rigorous image display, the dimming effect is poor.

[0094] Based on this, the present application provides a backlight zone dimming method and system for a display, which obtains a medical image to be displayed and determines the medical image type of the medical image to be displayed. Then, according to the medical image type, the backlight working area corresponding to the backlight substrate on the medical display is determined, so as to determine the corresponding target backlight lamp beads according to the backlight working area. According to the backlight working area, the medical image type and the preset step brightness, the dimming method corresponding to the target backlight lamp beads is determined, and the target backlight lamp beads are adjusted according to the dimming method, and the medical image is dimmed in a targeted manner, thereby improving the dimming effect.

[0095] Figure 1A schematic diagram of an application scenario provided for the present application. In a medical scenario, the method provided by the present application is applied. Specifically, the method provided by the present application is applied to any server. The server interacts with a transmission device that sends a medical image to be displayed and a medical display for displaying the medical image to be displayed. The server can first obtain the medical image to be displayed from the transmission device, and determine the backlight working area based on the image type of the medical image to obtain the target backlight lamp beads. The corresponding dimming method is set in combination with step brightness, etc. to adjust the target backlight lamp beads so that the medical image to be displayed is clearly displayed on the medical display. The specific implementation method can refer to the following embodiments.

[0096] Figure 2 This is a flow chart of a backlight zone dimming method for a display provided in an embodiment of the present application. The method of this embodiment can be applied to the server in the above scenario. Figure 2 As shown, the method includes:

[0097] S201. Acquire a medical image to be displayed, and determine the medical image type of the medical image to be displayed.

[0098] In the present application, a medical image to be displayed transmitted by a transmission device can be obtained, that is, an image that is to be clearly displayed by backlight partition dimming. The medical image to be displayed can be an X-ray, CT scan, MRI image, and the like. The type of medical image can be set according to different diagnostic and treatment images taken under different diagnostic and treatment conditions in medical scenarios, such as systemic skeletal X-ray images, local skeletal X-ray images, systemic computed tomography images, local computed tomography images, systemic magnetic resonance imaging images, local magnetic resonance imaging images, systemic ultrasound images, and local ultrasound images, etc.

[0099] Specifically, based on pre-set image features corresponding to different medical image types, image analysis may be performed on the medical image to be displayed, thereby determining the medical image type of the medical image to be displayed.

[0100] S202. Determine a backlight working area corresponding to a backlight substrate on a medical display according to the type of medical image, and determine a corresponding target backlight lamp bead according to the backlight working area.

[0101] In the present application, the medical display comprises a backlight substrate, on which a large number of backlight lamp beads are arranged, and these backlight lamp beads can be divided into different backlight working areas according to requirements, wherein the backlight working areas can be multiple, and some overlapping areas may occur.

[0102] Specifically, the partitioning methods corresponding to different medical image types can be preset to directly obtain the preset and stored backlight working area, and determine which target backlight lamp beads are in the backlight working area according to the preset backlight substrate.

[0103] S203, determining a dimming mode corresponding to the target backlight lamp beads according to the backlight working area, the medical image type and the preset step brightness, and adjusting the target backlight lamp beads according to the dimming mode.

[0104] In this application, since the contents of the medical images are images of the whole or part of the human body, including whole or part images of bones, organs, meridians, nerves, muscles, blood vessels, etc. In order to display the images to medical staff clearly and with a sense of layering and three-dimensionality, the step brightness can be preset.

[0105] Specifically, a dimming mode determination model can be pre-set, and the backlight working area, medical image type and preset step brightness can be input into the dimming mode determination model to directly output the dimming mode corresponding to the target backlight lamp bead. Then, the lighting mode of the target backlight lamp bead can be adjusted according to the dimming mode.

[0106] Through the method provided by this embodiment, by first acquiring the medical image to be displayed and determining its type, the backlight can be more accurately zoned and dimmed according to the characteristics of different medical images. This helps to enhance the contrast, brightness and clarity of the image, thereby improving the medical staff's ability to recognize the details of the medical image, which is of great significance for the accurate diagnosis of the disease. Determining the working area on the backlight substrate according to the type of medical image, and selecting the target backlight lamp beads for dimming accordingly can avoid unnecessary backlight waste. This localized and precise backlight management can significantly improve the energy efficiency of the display, extend the service life of the display, and reduce energy consumption. Different types of medical images may require different display conditions to maximize their readability and visual effects. The present application dynamically adjusts the brightness of the backlight lamp beads to ensure that any type of medical image can be presented in the best state, thereby enhancing the image observation experience and diagnostic efficiency of medical staff.

[0107] In some embodiments, a medical image to be displayed can be acquired; image analysis can be performed on the medical image to be displayed to determine the corresponding image content, relevant human body parts, and display attributes of the relevant human body parts; and the corresponding medical image type can be determined based on the image content, relevant human body parts, and display attributes.

[0108] In the present application, the display attribute can be used to indicate the area occupied by the relevant human body part in the entire image, whether it is an image of the entire human body or an image of a part of the human body.

[0109] Specifically, the medical images to be displayed sent by medical imaging equipment such as X-ray machines, CT scanners, and MRI machines, i.e., transmission devices, can be obtained first. The main contents of the image, such as bone structure, soft tissue, and organ morphology, are analyzed using image processing algorithms (such as edge detection, texture analysis, and shape recognition). Based on the image content, a machine learning model (such as a convolutional neural network) or a preset template matching method is used to identify the human body parts involved in the image, such as the head, chest, abdomen, and limbs, and then the display attributes of the relevant human body parts are obtained.

[0110] The image content, related human body parts, and display attributes can then be used as labels to match the corresponding medical image type.

[0111] Through the method provided by this embodiment, by performing detailed image analysis on the medical image to be displayed, the image content, related human body parts and the display properties of these parts can be accurately determined. This precise analysis capability can correctly classify medical images into different types, providing an accurate basis for subsequent processing and display. After determining the type and specific characteristics of the medical image, targeted display optimization can be performed based on this information. For example, for X-rays containing complex bone structures, the display parameters can be adjusted to enhance the visibility of the bones; for MRI images that need to observe soft tissue details, the contrast and brightness settings can be optimized. This display optimization based on image type can significantly improve the clarity and readability of the image, thereby helping doctors to interpret image information more accurately.

[0112] In some embodiments, display requirements are determined according to the type of medical image; and the corresponding backlight working area is determined according to the type of medical image and the display requirements, so as to determine the target backlight lamp beads according to the backlight working area.

[0113] In this application, the display requirement can be used to indicate what content / part of the image needs to be highlighted under this type of medical image, or what level the whole image needs to be displayed.

[0114] Specifically, for the medical image type, the corresponding display requirements are obtained. The display requirements and the medical image type are input into the preset backlight working area division model, and the division method is output. The backlight working areas are divided according to the division method to obtain multiple backlight working areas, and the target backlight lamp beads are determined according to the backlight working areas.

[0115] Through the method provided in this embodiment, by determining the display requirements according to the type of medical image and accurately dividing the backlight working area accordingly, it is possible to ensure that the backlight beads on the medical display work in the most suitable manner, thereby significantly improving the contrast, brightness and color reproduction of the image. This is crucial for medical staff to accurately interpret medical images and discover detailed information, which helps to improve the accuracy and efficiency of diagnosis. By precisely controlling the backlight working area, unnecessary backlight waste is avoided. Different medical image types may require different display effects to highlight key information. By adjusting the backlight working area according to the type of medical image and display requirements, a more comfortable and intuitive visual experience can be provided for medical staff. When viewing medical images, medical staff can find key information faster, reduce visual fatigue, and improve job satisfaction.

[0116] In some embodiments, the structure and association relationship of multiple human body sub-parts in the corresponding human body part can also be determined according to the part characteristics of the human body part; and the stepped brightness can be generated according to the structure, association relationship and preset backlight bead setting method of the multiple human body sub-parts.

[0117] In this application, part features can be used to represent the shape, size and position relationship of bones, blood vessels, muscles, organs, etc., as well as the overall brightness of each human body part, the brightness contrast between various human body parts, etc. Step brightness can be the brightness difference of the backlight working area corresponding to different human body parts.

[0118] Specifically, based on the publicly available human body data, including but not limited to bone structure, blood vessel distribution, muscle morphology, and organ location, etc., the structure and association relationship corresponding to the part features can be determined based on these human body data.

[0119] Then, based on the preset step brightness calculation method, the preset parameters corresponding to the structure and association relationship conversion can be substituted to generate the corresponding step brightness.

[0120] Through the method provided by this embodiment, by deeply analyzing the part characteristics of the human body parts, the structure and correlation of multiple human body sub-parts can be accurately identified and presented. It helps to more realistically reflect the anatomical structure and spatial layout of human body parts in the backlight display, and provide more accurate and intuitive visual information for medical teaching, rehabilitation training, virtual reality and other fields. According to the structure and correlation of multiple human body sub-parts, and the preset backlight lamp bead setting method, a stepped brightness effect can be generated. This brightness difference not only enhances the layering of the image, but also makes different human body parts more visually distinct.

[0121] In some embodiments, the light characteristics of a human body part can be obtained; the basic brightness can be set according to the light characteristics and the working environment information of the medical display; and the stepped brightness can be generated according to the structure, association, backlight bead setting method and basic brightness.

[0122] In the present application, light characteristics can be used to characterize the absorption and reflection characteristics of light by various parts of the human body. The working environment information of the medical display can be used to indicate the setting environment of the medical display, and can include ambient brightness. The basic brightness can ensure that the entire image is illuminated, but it will not be too glaring. Based on the basic brightness, for areas with higher density and stronger light absorption such as bones, the brightness of the backlight beads can be appropriately increased to highlight their structural features. For thinner areas such as blood vessels that reflect less light, it is necessary to reduce the brightness of the backlight beads to reduce the interference of background light, improve the clarity of the imaging, and then generate step brightness. The backlight bead setting method may include the number of backlight beads, the setting position, the distance between adjacent beads, etc.

[0123] Specifically, the light characteristics of different parts of the human body are first obtained, and then the light brightness of the environment where the medical display is located detected by the sensor can be received. According to the ambient brightness, the brightness adjustment range of the medical display, the light characteristics of the human body parts and the preset calculation method, a basic brightness value that can illuminate the entire image without being too glaring is calculated, and the basic brightness value is set as the initial brightness of the medical display. Then the structure, association relationship, backlight bead setting method and basic brightness can be input into the step brightness generation model to directly output the step brightness.

[0124] Through the method provided in this embodiment, by accurately obtaining the light characteristics of human body parts and adjusting the brightness of the backlight beads accordingly, the display effect of medical images can be significantly improved. Different parts such as bones, muscles, and blood vessels have different absorption and reflection characteristics of light, and can present a clearer and three-dimensional visual effect under backlight adjustment. Setting the basic brightness according to the working environment information of the medical display, and generating stepped brightness based on the structure and correlation of human body parts on this basis can effectively avoid the problem of overexposure or darkening of the image, make the brightness distribution more reasonable, and improve the overall quality of the image. The generation of stepped brightness allows different parts of the human body to form a visual contrast between light and dark, enhances the layering of the image, helps to more clearly identify and understand the detailed information in the image, and improves the accuracy and efficiency of diagnosis.

[0125] In some embodiments, multiple brightnesses corresponding to the target backlight beads can be determined according to the medical image type and the step brightness; the changing methods of the multiple brightnesses can be determined according to the backlight working area and the medical image type; the multiple brightnesses and changing methods are determined as dimming methods to adjust the target backlight beads according to the dimming methods.

[0126] In the present application, the brightness change mode may represent the brightness change speed, duration, and final brightness, etc.

[0127] Specifically, first, multiple brightnesses corresponding to the medical image type can be matched in the stepped brightness. Determine the backlight working area, that is, divide the backlight area that needs special attention or adjustment according to the display requirements of the medical image. This can be done automatically through image processing technology, or it can be manually specified by relevant staff. Determine the change mode of multiple brightness levels according to the backlight working area and the medical image type. The change speed determines the speed at which the brightness transitions from the current level to the target level, which can be fast, smooth, or change according to a specific curve. The duration is the duration of each brightness level, which can be a fixed time or dynamically adjusted according to the image content. The final brightness is the final brightness level achieved, which can be determined based on the brightness and contrast requirements of the image content. Then, multiple brightnesses and the corresponding brightness change mode can be used as a dimming mode to adjust the target backlight beads according to the dimming mode.

[0128] Through the method provided in this embodiment, by determining multiple suitable brightness levels for the target backlight beads according to the medical image type and the preset step brightness, the display effect of the medical image can be significantly improved. Different image types have different requirements for brightness and contrast due to their different imaging principles and information presentation methods. The present application can accurately dim the image for different image types, making the details in the image clearer and the structure more distinct, thereby improving the diagnostic accuracy of medical staff. According to the backlight working area and the medical image type, multiple brightness change methods, such as change speed, duration, etc., are determined to further enhance the layering of the image.

[0129] In some embodiments, the backlight working area corresponding to the backlight substrate can be determined according to the type of medical image; the working status of multiple optional backlight lamp beads in the backlight working area can be detected; in the case where any optional backlight lamp bead is a damaged lamp bead, the replaceable lamp bead is determined according to the lamp bead properties of the damaged lamp bead, so as to determine the target backlight lamp bead based on the multiple optional backlight lamp beads and the replaceable lamp beads; wherein the damaged lamp bead is an optional backlight lamp bead with an abnormal working status.

[0130] In this application, the abnormal working state may include the lamp bead not lighting up, the lamp bead flickering, and the brightness being different from the level that should be bright. The lamp bead attribute can be used to characterize the arrangement of the lamp bead on the backlight substrate. Replaceable lamp bead is used to indicate a lamp bead that can replace a damaged lamp bead to continue to work by emitting light.

[0131] Specifically, the corresponding backlight working area is first determined according to the medical image type in the above manner, and the working status of multiple optional backlight beads in the area is detected. If there is an optional backlight bead that is a damaged bead, the replaceable bead can be determined in combination with the bead properties of the damaged bead. Specifically, an association between the bead properties and the replaceable bead can be established in advance, so as to determine the determination method of searching for replaceable beads based on the association, obtain the replaceable bead, and then determine the target backlight bead.

[0132] By using the method provided in this embodiment, by determining the backlight working area according to the type of medical image, it is possible to ensure that the backlight light accurately illuminates the key areas in the image, thereby optimizing the brightness, contrast and clarity of the image. When the lamp beads in the backlight working area are detected to be damaged, replaceable lamp beads can be quickly identified and found for replacement. This not only avoids the decline in the overall backlight effect due to damage to a single lamp bead, but also significantly extends the service life of the backlight system and reduces the cost of maintenance and replacement.

[0133] In some embodiments, when any optional backlight bead is a damaged bead, the bead properties of the damaged bead can be obtained; the position information of the damaged bead on the backlight substrate and the distance between the damaged bead and the optional backlight bead can be determined from the bead properties; the position range of replaceable bead can be determined based on the position information and the distance; the optional backlight bead within the position range of replaceable bead can be determined as replaceable bead; and the target backlight bead can be determined based on multiple optional backlight bead and replaceable bead.

[0134] In the present application, when selecting replaceable lamp beads to replace damaged lamp beads, the position range of the replaceable lamp beads can ensure normal replacement. Lamp beads selected outside this range may result in poor replacement effect.

[0135] Specifically, if any of the optional backlight lamp beads is a damaged lamp bead, the lamp bead properties of the damaged lamp bead are obtained, and then the position information of the damaged lamp bead and the distance between the damaged lamp bead and the adjacent optional backlight lamp bead are extracted from the lamp bead properties.

[0136] Based on the location information, distance and pre-set lamp bead properties, such as the material of the lamp bead, the illumination range, etc., the range is input into the range determination model, and the replaceable lamp bead position range is directly output. Then the lamp beads within the range are regarded as replaceable lamp beads, and the target backlight lamp beads are determined according to the optional backlight lamp beads and replaceable lamp beads.

[0137] Through the method provided by this embodiment, when a certain lamp bead in the backlight system is damaged, the damaged lamp bead can be quickly identified and located, and then a replaceable lamp bead can be found within a suitable position range based on its lamp bead properties. This not only avoids the degradation of the overall backlight effect caused by the damage of a single lamp bead, but also significantly improves the stability and reliability of the backlight system. By accurately matching the lamp bead properties of the damaged lamp bead, the closest replaceable lamp bead can be found, thereby ensuring that the backlight effect after replacement is as consistent as possible with the original effect. This helps to maintain the high quality and clarity of medical images and provide accurate diagnostic basis for medical staff.

[0138] In some embodiments, the positional relationship between normally operating lamps and replaceable lamp beads can be obtained; wherein, the normally operating lamp beads are multiple optional backlight lamp beads other than damaged lamp beads; based on the positional relationship, the impact information on the overall backlight effect is determined; based on the impact information, the target replacement lamp beads are determined from the replaceable lamp beads, so as to determine the normally operating lamp beads and the target replacement lamp beads as the target backlight lamp beads.

[0139] In the present application, the impact information can be used to characterize the impact of a damaged lamp bead on other lamp beads, that is, the brightness of which lamp beads' coordination will be affected due to the damaged lamp bead.

[0140] Specifically, the positional relationship between the normally operating lamp beads and the replaceable lamp beads is obtained, and based on the positional relationship, the preset corresponding impact information is searched. Then, the impact information and the position and positional relationship of the replaceable lamp beads can be input into the preset target replacement lamp bead determination model, the position of the target replacement lamp bead is output, and then the target replacement lamp bead and the normally operating lamp bead are used as a whole as the target backlight lamp bead.

[0141] Through the method provided by this embodiment, by considering the position of each replaceable lamp bead and its potential impact on the backlight effect, the present application can ensure that the selected target replacement lamp bead can maintain the original performance of the medical display to the greatest extent after replacement. By accurately matching the position and properties of the normally operating lamp bead with the replaceable lamp bead, the uneven backlighting caused by the damage of a single lamp bead is effectively reduced, and the overall visual effect of the display is improved.
