Abstract
Description
Display device and control method thereof
[0001] The disclosed invention relates to a display device for correcting an image and identifying a predetermined area in the corrected image, and a control method thereof.
[0002] Feature points from human images are commonly used in various technical fields. In particular, features extracted from human facial images are useful in facial recognition technology, where they can be used to identify objects within the image. These features can also be utilized in the medical field.
[0003] As science and technology advance, technologies (Telehealth, Telemedicine, or Home-Care) are being developed that can diagnose a patient's health status or abnormalities by analyzing only the patient's images from a distance without the doctor having to meet the patient directly.
[0004] In order to make a diagnosis through a patient's image, it is important to accurately detect characteristic points in the image.
[0005] However, when acquiring patient images, the lighting conditions of the patient's room can lead to images of the patient being darkened, or the patient can be backlit depending on the relative position of the camera and lighting. This makes it difficult to detect feature points in patient images, and it also hinders the smooth identification of areas for vital signs detection.
[0006] Additionally, when the patient's skin tone is dark or the face is tilted, there was difficulty identifying areas in the patient's image for detecting vital signs. This made it difficult to properly diagnose and diagnose patients using the patient's image during remote consultations.
[0007] One aspect of the disclosed invention provides a display device and a control method thereof for identifying a predetermined detection area by correcting the brightness of a screen or image.
[0008] One aspect includes a display unit; a communication unit for performing communication with an external device; at least one memory for storing one or more commands; and at least one processor for executing one or more commands. One or more commands for causing a display device to operate when the at least one processor is executed include displaying an image on the display unit based on image information received through the communication unit, identifying one or more feature points and an omega shape of a patient included in the image, identifying whether the image includes a predetermined detection area related to biometric information of the patient based on the one or more feature points and the omega shape, and adjusting a display parameter of at least one of the display unit and the image based on whether the predetermined detection area is identified.
[0009] One or more instructions for causing the display device to operate when at least one processor is executed include: identifying a central axis of the image; identifying a left side and a right side of the patient in the image based on the central axis, the omega shape and the identification of one or more feature points; identifying whether a left feature point of the left side of the patient is included in the one or more feature points; identifying whether a right feature point of the right side of the patient is included in the one or more feature points; and mapping a feature point between the left feature point and the right feature point included in the one or more feature points to the opposite side of the image based on the identification that only one of the left feature point and the right feature point is included in the one or more feature points.
[0010] One or more instructions for causing the display device to operate when at least one processor is executed include controlling the communication unit to transmit environmental guidance information to an external device based on identifying that the image does not include at least one of one or more feature points and an omega shape. The environmental guidance information includes information related to adjusting the patient's posture and position.
[0011] One or more instructions for causing the display device to operate when at least one processor is executed include adjusting display parameters of an image based on illuminance information received through the communication unit and predetermined reference illuminance information.
[0012] One or more instructions for causing the display device to operate when at least one processor is executed include controlling the communication unit to transmit environmental guide information for illuminance adjustment to an external device based on illuminance information received through the communication unit and predetermined reference illuminance information.
[0013] One or more instructions for causing the display device to operate when at least one processor is executed performs image preprocessing to uniformize the brightness of the image based on the image being identified as having non-uniform brightness.
[0014] At least one memory stores the patient's baseline biometric information. One or more commands for causing the display device to operate when at least one processor is executed include controlling the communication unit to detect the patient's biometric information in a predetermined detection area based on the diagnosis request information received through the communication unit, acquire diagnostic result information based on the detected biometric information and the stored baseline biometric information, and transmit the acquired diagnostic result information to an external device.
[0015] One or more instructions for causing the display device to operate when at least one processor is executed include: identifying whether the image information is image information acquired in a backlit environment based on brightness information of the image information, based on an omega shape being identified and one or more feature points not being identified; adjusting a display parameter of the image based on the image information being identified as image information acquired in a backlit environment; and performing preprocessing of the image to uniformize the brightness of the image.
[0016] One or more instructions for causing a display device to operate when at least one processor is executed include: acquiring illuminance information from an external device through a communication unit based on an omega shape being identified and one or more feature points not being identified; identifying whether illuminance of a space in which the external device is provided is less than a first reference illuminance and greater than a second reference illuminance based on the acquired illuminance information and first and second reference illuminance information; identifying that received image information is image information acquired in a backlit environment if the illuminance of the space is less than the first reference illuminance and greater than the second reference illuminance; and transmitting environment guide information to the external device if the illuminance of the space is less than the second reference illuminance. The second reference illuminance is an illuminance lower than the first reference illuminance. The environment information includes information related to adjusting the illuminance of the space.
[0017] The one or more feature points include one or more feature points of the patient's face, and the one or more feature points of the face include the ends of the eyes, the ends of the mouth, and the bridge of the nose. The predetermined detection area includes the orbital area of the face and the infraorbital area of the face.
[0018] One or more instructions for causing the display device to operate when at least one processor is executed include obtaining a skin reflection coefficient of a patient based on first image information acquired in a lighting environment and second image information acquired in a non-illuminated environment received from an external device, and transmitting illuminance information corresponding to the skin reflection coefficient to the external device.
[0019] A method for controlling a display device according to another aspect includes identifying one or more characteristic points and an omega shape of a patient based on image information received from an external device through a communication unit, identifying whether the image information includes a detection area related to the patient's biometric information based on the identification of the one or more characteristic points and the identification of the omega shape, and adjusting a display parameter of at least one of the image information or a display unit of the display device based on the identification of the detection area.
[0020] A method for controlling a display device according to another aspect further includes transmitting first environment guide information for guiding position and posture adjustment of a patient to an external device based on the identification of one or more feature points and an omega shape in image information, identifying an environment of a space in which the external device is provided as a backlight environment based on the identification of the omega shape and the identification of one or more feature points in the image information, adjusting display parameters of a display unit, performing preprocessing of image information to uniformize the brightness of an image displayed on the display unit, and transmitting second environment guide information for illuminance adjustment to the external device based on illuminance information and reference illuminance information received from the external device through a communication unit.

[0049] The operating principle and embodiments of the present invention will be described with reference to the attached drawings below.
[0050] FIG. 1 is an exemplary diagram of a display system (1) including first and second display devices according to one embodiment.
[0051] The display system (1) can be implemented in a cloud manner through an Internet network built online.
[0052] The display system (1) may include two or more display devices (100, 200) provided in different spaces.
[0053] The display system (1) may further include a user device (2) and may further include a server (3).
[0054] Hereinafter, a display system including two display devices will be described. To distinguish between the two display devices, they will be referred to as a first display device (100) and a second display device (200).
[0055] The first display device (100) may be a device installed in a medical institution, and the second display device (200) may be a device installed in a home or office.
[0056] The first and second display devices (100, 200) may include a display unit that displays an image sensor and a screen. The first and second display devices (100, 200) may further include a microphone and a speaker. The first and second display devices (100, 200) may further include lighting.
[0057] The first display device (100) may be a television or a user device.
[0058] The first display device (100) may include a communication module capable of communicating with a user device (2) or a server (3), a user interface for receiving user input or outputting information to a user, at least one processor for controlling the operation of the first display device (100), and at least one memory in which a program for controlling the operation of the first display device (100) is stored.
[0059] The second display device (200) may be a home appliance or a user device.
[0060] The second display device (200) may include a communication module capable of communicating with another home appliance (10), a user device (2), or a server (3), a user interface for receiving user input or outputting information to a user, at least one processor for controlling the operation of the second display device (200), and at least one memory storing a program for controlling the operation of the second display device (200).
[0061] Other home appliances (10) may include, but are not limited to, at least one of a refrigerator (11), a dishwasher (12), an electric range (13), an electric oven (14), an air conditioner (15), a clothes manager (16), a washing machine (17), a dryer (18), and a microwave oven (19) as illustrated, and may include various types of home appliances such as, for example, a cleaning robot, a vacuum cleaner, and a television.
[0062] In addition, the aforementioned home appliances are merely examples, and in addition to the aforementioned home appliances, other home appliances, user devices (2), or devices that are connected to a server (3) and can perform the operations described below may be included in the second display device (200) according to one embodiment.
[0063] The server (3) may include a communication module capable of communicating with another server, the first and second display devices (100, 200), or the user device (2), at least one processor capable of processing data received from another server, the first and second display devices (100, 200), or the user device (2), and at least one memory capable of storing a program for processing data and / or processed data.
[0064] These servers (3) can be implemented as various computing devices such as workstations, clouds, data drives, and data stations. The servers (3) can be implemented as one or more servers that are physically or logically separated based on function, detailed configuration of function, or data, and can transmit and receive data and process the transmitted and received data through communication between each server.
[0065] The server (3) can perform functions such as managing user accounts, registering first and second display devices (100, 200) by linking them to user accounts, and managing or controlling the registered first and second display devices (100, 200). For example, a user can access the server (3) through a user device (2) and create a user account. The user account can be identified by an ID and password set by the user. Here, the user can be a doctor linked to the first display device (100) and a patient linked to the second display device (200).
[0066] The server (3) can register the first and second display devices (100, 200) to a user account according to a set procedure. For example, the server (3) can register, manage, and control the first and second display devices (100, 200) by linking the identification information (e.g., serial number or MAC address) of the first and second display devices (100, 200) to the user account.
[0067] The user device (2) may include a communication module capable of communicating with the first display device (100), the second display device (200) or the server (3), a user interface for receiving user input or outputting information to the user, at least one processor for controlling the operation of the user device (2), and at least one memory in which a program for controlling the operation of the user device (2) is stored.
[0068] The user device (2) may be carried by the user or placed in the user's home, office, or medical institution. The user device (2) may include, but is not limited to, a personal computer, a terminal, a portable telephone, a smart phone, a handheld device, a wearable device, etc.
[0069] The memory of the user device (2) may store a program, i.e., an application, for controlling the first display device (100) or the second display device (200). The application may be sold installed on the user device (2) or downloaded and installed from an external server.
[0070] A user can access a server (3) by executing an application installed on a user device (2), create a user account, and perform communication with the server (3) based on the logged-in user account to register a first display device (100) or a second display device (200).
[0071] For example, when the first display device (100) is operated so that the first display device (100) can be connected to the server (3) according to the procedure guided by the application installed on the user device (2), the first display device (100) can be registered in the user account by registering the identification information (e.g., serial number or MAC address) of the first display device (100) in the corresponding user account on the server (3).
[0072] When the second display device (200) is operated so that the second display device (200) can be connected to the server (3) according to the procedure guided by the application installed on the user device (2), the second display device (200) can be registered in the user account by registering the identification information (e.g., serial number or MAC address) of the second display device (200) in the corresponding user account on the server (3).
[0073] A user can control the first display device (100) using an application installed on the user device (2). For example, when a user logs into a user account using an application installed on the user device (2), the first display device (100) registered to the user account appears, and when a control command for the first display device (100) is input, the control command can be transmitted to the first display device (100) via the server (3).
[0074] A user can control a second display device (200) using an application installed on the user device (2). For example, when a user logs into a user account using an application installed on the user device (2), a second display device (200) registered to the user account appears, and when a control command for the second display device (200) is input, the control command can be transmitted to the second display device (200) via the server (3).
[0075] A network can include both wired and wireless networks. Wired networks include cable networks or telephone networks, while wireless networks can include any network that transmits and receives signals via radio waves. Wired and wireless networks can be interconnected.
[0076] A network may include a wide area network (WAN) such as the Internet, a local area network (LAN) formed around an access point (AP), and a short-range wireless network that does not use an access point (AP). Short-range wireless networks may include, but are not limited to, Bluetooth (IEEE 802.15.1), Zigbee (IEEE 802.15.4), Wi-Fi Direct, Near Field Communication (NFC), Z-Wave, etc.
[0077] An access point (AP) can connect the first and second display devices (100, 200) or the user device (2) to a wide area network (WAN) to which the server (3) is connected. The first and second display devices (100, 200) or the user device (2) can be connected to the server (3) via the wide area network (WAN).
[0078] The access point (AP) can communicate with the second display device (200) or the user device (2) using wireless communication such as Wi-Fi (IEEE 802.11), Bluetooth (IEEE 802.15.1), or Zigbee (IEEE 802.15.4), and can connect to a wide area network (WAN) using wired communication, but is not limited thereto.
[0079] According to various embodiments, the first and second display devices (100, 200) may be directly connected to the user device (2) or the server (3) without going through an access point (AP).
[0080] The first and second display devices (100, 200) can be connected to a user device (2) or a server (3) via a long-distance wireless network or a short-distance wireless network.
[0081] For example, the first and second display devices (100, 200) can be connected to the user device (2) via a short-range wireless network (e.g., Wi-Fi Direct).
[0082] As another example, the first and second display devices (100, 200) may be connected to a user device (2) or a server (3) via a wide area network (WAN) using a long-distance wireless network (e.g., a cellular communication module).
[0083] As another example, the first and second display devices (100, 200) can be connected to a wide area network (WAN) using wired communication and connected to a user device (2) or a server (3) through the wide area network (WAN).
[0084] If the second display device (200) can connect to a wide area network (WAN) using wired communication, it may also function as a connection relay. Accordingly, the second display device (200) can connect other home appliances (10) to the wide area network (WAN) to which the server (3) is connected.
[0085] The second display device (200) can transmit information about its operation or status to the user device (2) or the server (3) via a network. For example, the second display device (200) can transmit information about its operation or status to the user device (2) or the server (3) when a request is received from the server (3), when a specific event occurs in the second display device (200), or periodically or in real time.
[0086] When information about the operation or status is received from the first display device (100) or the second display device (200), the server (3) updates the stored information about the operation or status of the first display device (100) or the second display device (200), and transmits the updated information about the operation and status of the first display device (100) or the second display device (200) to the user device (2) via the network. Here, updating information may include various operations in which existing information is changed, such as an operation of adding new information to existing information, an operation of replacing existing information with new information, etc.
[0087] The first display device (100) or the second display device (200) can obtain various information from the user device (2) or the server (3) and provide the obtained information to the user. For example, the first display device (100) or the second display device (200) can obtain information related to the function of the first display device (100) or the second display device (200) (e.g., non-face-to-face treatment, etc.) and information on various environmental information (e.g., illuminance, etc.) from the server (3) and output the obtained information through the user interface.
[0088] The first display device (100) or the second display device (200) can operate according to a control command received from the user device (2) or the server (3). For example, if the first display device (100) or the second display device (200) has obtained prior approval from the user so that it can operate according to the control command of the server (3) even without user input, the first display device (100) or the second display device (200) can operate according to the control command received from the server (3). Here, the control command received from the server (3) may include, but is not limited to, a control command input by the user through the user device (2) or a control command based on a preset condition.
[0089] The user device (2) can transmit information about the user to the first display device (100), the second display device (200), or the server (3) via the communication module. For example, the user device (2) can transmit information about the user's location, the user's health status, the user's preferences, the user's schedule, etc. to the server (3). The user device (2) can transmit information about the user to the server (3) with the user's prior consent.
[0090] The first display device (100) or the second display device (200), the user device (2), or the server (3) can determine a control command using technology such as artificial intelligence. For example, the server (3) can receive information about the operation or status of the first display device (100) or the second display device (200) or receive information about the user of the user device (2), process the information using technology such as artificial intelligence, and transmit the processing result or control command to the first display device (100), the second display device (200), or the user device (2) based on the processing result.

In this case, the first processor (150) can compare the reference biometric information with the diagnostic biometric information to acquire diagnostic information and control the first display unit (160) to display the acquired diagnostic information.
[0127] When the first processor (150) receives treatment request information and patient identification information from the second display device (200), it can control the first display unit (160) to display the received treatment request information and patient identification information.

Here, the patient's image information for diagnosis may be original image information transmitted from the second display device (200) or image information whose color has been corrected using a color patch.
[0143] More specifically, when performing a diagnosis, the first processor (150) can detect body features and determine whether the body is symmetrical on both sides. Hereinafter, the patient's face will be used as an example to explain the patient's body.
[0144] The first processor (150) detects feature points for each face landmark based on a face image and performs labeling on a plurality of detected feature points. The landmarks may include eyes, nose, mouth, eyebrows, and chin.
[0145] That is, multiple feature points can include location information and labeling information.
[0146] As shown in FIG. 3, the first processor (150) can label the right end point of the right eye as 1-1, the left end point of the right eye as 1-2, the left end point of the left eye as 2-1, the right end point of the left eye as 2-2, the right end point of the mouth as 3-1, the left end point of the mouth as 3-2, and the nose, etc. as 4.
[0147] The first processor (150) can determine whether all landmark feature points on the left and right sides of the face image have been detected based on the location information and labeling information for each feature point.
[0148] For example, the first processor (150) can determine whether the right end point 1-1 of the right eye of the right face image, the left end point 1-2 of the right eye, and the right end point 3-1 of the mouth have all been detected, and can determine whether the left end point 2-1 of the left eye of the right face image, the right end point 2-2 of the left eye, and the left end point 3-2 of the mouth have all been detected.
[0149] The first processor (150) can determine whether all left feature points of the left face image have been detected based on labeling information of left feature points of the pre-stored left face image, labeling information of right feature points of the pre-stored right face image, and labeling information of a plurality of detected feature points, and can determine whether all right feature points of the right face image have been detected.
[0150] As illustrated in FIG. 3, if the first processor (150) determines that all feature points of the left and right facial images have been detected in the patient's image, it can identify the detection area (vs1, vs2) of the biosignal based on the feature points of the left and right facial images in the image.
[0151] The detection area of the biosignal (vs1, vs2) may be a predetermined detection area.
[0152] The first processor (150) determines whether the illuminance of the second space is equal to or greater than the first reference illuminance based on the illuminance information received from the second display device (200) and the first reference illuminance information, and if it is determined that the illuminance of the second space is equal to or greater than the first reference illuminance and if it is determined that all feature points of the left and right facial images have been detected in the image received from the second display device (200), it is also possible to identify a detection area of a biosignal based on the feature points of the left and right facial images in the image.
[0153] The second space is a space where a second display device (200) is provided, and may be a space where a patient lives.
[0154] If the first processor (150) determines that at least one feature point among the feature points of the left and right facial images is not detected, it can determine whether or not an omega shape (Ω-Shape) is detected based on the facial image.
[0155] The first processor (150) can also detect feature points of a facial image and determine whether an omega shape (Ω-Shape) is detected based on the facial image.
[0156] The first processor (150) can determine whether the facial image is symmetrical left and right based on the detected omega shape.
[0157] If the first processor (150) determines that the left and right sides of the facial image are not symmetrical, it can transmit environmental guide information that guides the patient's posture and position adjustment to the second display device (200).
[0158] Determining that the left and right sides of the facial image are not symmetrical may include determining that the patient is not looking at the second image sensor (220).
[0159] Determining that the patient is not looking at the second image sensor (220) may include determining whether the second image sensor and the patient's face are facing each other.
[0160] For example, the first processor (150) may obtain a difference value between the size of the left face image and the size of the right face image based on the central axis, and if the obtained size difference value is greater than a certain value, it may be determined that the patient is not looking at the second image sensor (220).
[0161] The first processor (150) can determine whether an omega shape has been detected, and if it is determined that an omega shape has not been detected, it can transmit environmental guide information that guides the patient's posture and position adjustment to the second display device (200).
[0162] As shown in Fig. 4, detecting the Ω-Shape is to detect the outline from the tip of the patient's head (i.e., crown) to the shoulder line in the patient's face image.
[0163] The first processor (150) can set or identify a point such as the nose at the center of the patient's head (crown) recognized in the image as a center pole, and can divide the face image into a left face image and a right face image based on the set center axis.
[0164] The first processor (150) can also set the center axis (center pole) from the center of the patient's head (i.e., crown) to the center of the jaw.
[0165] The center of the patient's head can be the center of the omega shape, the point where the derivative becomes zero.
[0166] As illustrated in FIG. 5A, if the first processor (150) determines that an omega shape has been detected, it divides the face into left and right, and determines whether all feature points of the divided left and right face images exist. At this time, the first processor (150) can determine whether at least one feature point of either the left feature point of the left face image or the right feature point of the right face image has not been detected.
[0167] The first processor (150) can check the location information of the feature points of the face image of the side on which all feature points are detected among the left and right faces, and map the feature points to the face image of the side on which at least one feature point is not detected (i.e., the side with the missing feature point) based on the location information of the checked feature points and the central axis.
[0168] As illustrated in FIG. 5b, if the first processor (150) determines that at least one feature point among the left feature points of the left face image is not detected, the first processor (150) can identify the right feature point of the right face image corresponding to the landmark of the missing feature point, that is, the feature point that is not detected (i.e., the detected feature point), and map the right feature points of the right face image to the left face based on the set central axis. That is, the first processor (150) can map the identified right feature point of the right face image to the left face image based on the central axis.
[0169] As illustrated in FIG. 5c, the first processor (150) generates feature points of the left and right facial images in response to the detection of the omega shape and the mapping of feature points of the left and right facial images, and can identify a detection area (vs1, vs2) of a biosignal based on the feature points of the generated left and right facial images.
[0170] Generating feature points of the left and right facial images in the image is to generate feature points that are not detected through the image received from the second display device.
[0171] The first processor (150) can check the biosignal in the detection area of the identified biosignal and determine the patient's health status based on the checked biosignal.
[0172] The first processor (150) can control the first display unit to diagnose the patient's condition based on the confirmed bio-signal and display the diagnosed diagnosis result information, and can transmit the diagnosis result information to the second display device.
[0173] The detection area of the biosignal may be an area selected by the user (i.e., the doctor).
[0174] The detection area of the biosignal may be the affected area.
[0175] When the body is a face, the detection area of the biosignal may include the orbital area and the infraorbital area under the eyes of the left and right facial images.
[0176] If the body is a face, the detection area of the biosignal may include the pupil.
[0177] The first processor (150) can also determine the patient's condition, i.e., the improved condition and the worsened condition, based on the diagnosis result information and the diagnosis history information.
[0178] The first processor (150) can also determine whether the environment of the second space is a low-illuminance environment or an extremely low-illuminance environment based on the illuminance information received from the second display device and the first and second reference illuminance information.
[0179] That is, the first processor (150) determines whether the illuminance of the second space is less than the first reference illuminance based on the illuminance information received from the second display device (200), and if the illuminance of the second space is determined to be less than the first reference illuminance, the environment of the second space is determined to be a low-illuminance environment.
[0180] The first processor (150) determines that the illuminance of the second space is less than the first reference illuminance and greater than the second reference illuminance based on the illuminance information received from the second display device (200), and if the illuminance of the second space is determined to be less than the first reference illuminance and greater than the second reference illuminance, the environment of the second space can be determined to be a low-illuminance environment.
[0181] The first processor (150) determines whether the illuminance of the second space is less than the second reference illuminance based on the illuminance information received from the second display device (200), and if the illuminance of the second space is determined to be less than the second reference illuminance, determines that the environment of the second space is an extremely low illuminance environment, and transmits environment guide information that guides the brightness adjustment of the second lighting to the second display device (200). The second reference illuminance may be an illuminance lower than the first reference illuminance.
[0182] The first processor (150) can obtain brightness information of an image based on image information received from the second display device (200) and can also determine whether the environment of the second space is a low-light environment based on the brightness information of the obtained image.
[0183] The first processor (150) can obtain brightness information between the body area and the background area from the image received from the second display device (200) and determine whether the image was obtained in a backlit environment based on the obtained brightness information.
[0184] If the first processor (150) determines that the patient's image was acquired in a backlit or low-light environment, it can perform preprocessing to improve the brightness of the face area in the image using an uneven illumination image enhancement technology or a low-light image enhancement technology.
[0185] If the first processor (150) determines that the environment of the second space is a low-light environment, it can transmit environment guide information that guides brightness adjustment of the second display unit or brightness adjustment of the second light (190) to the second display device (200).
[0186] If the environment of the second space is determined to be a low-light environment or a backlit environment, the first processor (150) can control brightness adjustment of the first display unit or perform image preprocessing for uneven lighting.

[0189] If the first processor (150) determines that the omega shape is not detected and that the feature points of the left and right facial images are not detected, it may determine that patient recognition has failed and transmit environmental guide information that guides the patient's position and posture adjustment to the second display device (200).
[0190] If the first processor (150) determines that the environment of the second space is a low-light environment, that an omega shape is detected, and that feature points of the left and right facial images are not detected, it can determine that the environment is a low-light backlight environment and transmit environment guide information that guides brightness adjustment of the second lighting of the second space to the second display device (200).
[0191] If the first processor (150) determines that the environment of the second space is a low-light environment, an omega shape is detected, and only the feature points of the face image of one side (the first side) among the feature points of the left and right face images are all detected, the first processor corrects the brightness of the face image, and generates feature points of the face image of the second side based on the corrected image information, the feature points of the face image of the first side, and the information on the central axis of the omega shape, and then identifies a detection area of a biosignal based on the feature points of the left and right face images.
[0192] If the first processor (150) determines that the illuminance of the second space is higher than the first reference illuminance, that an omega shape is detected, and that feature points of the left and right facial images are not detected, it determines that it is a backlight environment and corrects the brightness of the facial image, and based on the corrected image information, it re-detects feature points of the left and right facial images, and based on the re-detected feature points of the left and right facial images, it can identify a detection area of a biosignal.
[0193] That is, if the first processor (150) determines that the illuminance of the second space is higher than the first reference illuminance and that it is a backlight environment, it can perform preprocessing to improve the brightness of the face area in the image using an illuminance unevenness image enhancement technology or a low-light image enhancement technology.
[0194] If the first processor (150) determines that the illuminance of the second space is equal to or greater than the first reference illuminance, that an omega shape is detected, and that only the feature points of the facial image of one side (the first side) among the feature points of the left and right facial images are all detected, the first processor (150) generates feature points of the facial image of the second side based on the feature points of the facial image of the first side and the information of the central axis of the omega shape, and then identifies a detection area of a biosignal based on the feature points of the left and right facial images.

[0311] Figure 8 is a control flowchart of a first display device according to one embodiment.
[0312] When the first display device receives treatment request information and patient identification information from the second display device (200), the first display device can display the received treatment request information and patient identification information through the first display unit (160).
[0313] When a treatment approval command is received through the first input interface (110), the first display device can transmit the received treatment approval command and guidance information for non-face-to-face treatment to the second display device (200).
[0314] When the first display device receives image information of a patient from the second display device (200), the first display device can display the received image information of the patient through the first display unit (160).
[0315] When the first display device displays the patient's image information through the first display unit (160), the first display device can identify the image information of the color patch in the patient's image information received from the second display device (200), acquire the color information of the color patch based on the image information of the identified color patch, acquire color correction information based on the color information of the acquired color patch and the color information of the pre-stored color patch, correct the patient's image information based on the acquired color correction information, and display the corrected image information.
[0316] The first display device can transmit the corrected image information to the second display device (200). In this case, the second display device (200) can display the corrected image information through the second display unit.
[0317] The first display device acquires (401) the illuminance information transmitted from the second display device (200), and determines (402) whether the illuminance of the second space is equal to or greater than the first reference illuminance based on the acquired illuminance information and the first reference illuminance information. Here, the second space may be a space where a patient is located and where remote, non-face-to-face treatment is performed.
[0318] If the first display device determines that the illuminance of the second space is lower than the first reference illuminance, the first display device can transmit environmental guide information guiding the brightness adjustment of the second light (290) to the second display device (403). That is, the first display device can transmit environmental guide information guiding the lighting of the second light (290) or environmental guide information guiding the brightness adjustment of the second light so that the brightness of the second light increases to the second display device.
[0319] The first display device can control the first display unit so that the brightness of the first display unit becomes brighter.
[0320] If the first display device determines that the illuminance of the second space is lower than the first reference illuminance, it is also possible to transmit environmental guide information that guides brightness adjustment of the second display unit (260) to the second display device (200).
[0321] The first display device can recognize a detection area of a biosignal based on the re-received facial image when the facial image is re-received from the second display device in response to the transmission of environmental guide information. In this case, the first display device can also obtain the illumination information transmitted from the second display device (200) and determine whether the illumination of the second space is equal to or greater than the first reference illumination based on the obtained illumination information and the first reference illumination information.
[0322] The first display device can acquire a face image by recognizing the face based on image information when it is determined that the illuminance of the two spaces is greater than the first reference illuminance (404).
[0323] The first display device can detect an omega shape based on the acquired facial image. At this time, the first display device can determine whether an omega shape has been detected in the facial image (405).
[0324] If the first display device determines that an omega shape has not been detected, the first display device may transmit environmental guidance information to the second display device, guiding the patient's posture and position adjustment (406). In this case, the second display device may display environmental guidance information guiding the patient to look at the second image sensor and take a picture of the body or face.
[0325] The first display device performs detection of feature points of the facial image when it is determined that an omega shape has been detected (407).
[0326] When the first display device determines that feature points of a facial image have been detected, it labels the detected feature points and can obtain a bridge of the nose point based on the labeled information.
[0327] The first display device identifies the crown in the omega shape and connects the identified crown and the bridge of the nose to establish the central axis.
[0328] The first display device can distinguish between a left face image and a right face image based on a set central axis, and determine whether all feature points of the left face image and the right face image have been detected based on labeling information of feature points of the left face image stored in advance, labeling information of feature points of the right face image stored in advance, labeling information of feature points of the detected left face image, and labeling information of feature points of the detected right face image (408).
[0329] If the first display device determines that neither the left face image nor the right face image feature points are detected, it checks the face on which neither the left face image feature points nor the right face image feature points are detected.
[0330] If the first display device determines that neither the feature points of the left face image nor the feature points of the right face image are detected, it determines that the environment of the second space is a backlit environment, adjusts the brightness of the first display unit, and preprocesses the face image to improve uneven lighting (410).
[0331] The first display device can re-detect feature points of the facial image based on the image-processed facial image.
[0332] The first display device may determine that the face in the face image is asymmetrical if it determines that at least one of the feature points of the face image on the first side among the left and right face images is not detected. In this case, the first display device may generate all feature points of the face image on the first side by mapping (411) the feature points of the face image on the second side (i.e., the side with the detected feature point) to the face image on the first side (the side corresponding to the missing feature point) based on the central axis of the omega shape.
[0333] The first display device can identify a predetermined detection area based on feature points of the left and right facial images (412). Here, the predetermined detection area may be an area for detecting a biosignal. In other words, the first display device can identify a detection area for a biosignal in the left and right facial images.
[0334] The first display device can recognize biosignal information in a biosignal detection area and diagnose the patient's health status based on the recognized biosignal information and reference biosignal information (413).
[0335] The first display device can generate diagnostic result information for the diagnostic result, display the generated diagnostic result through the first display unit, and transmit it to the second display device (414).
[0336] The first display device can also identify a detection area for a biosignal based on a facial image received when the illuminance of the second space is below the first reference illuminance. The control sequence of the first display device in this case is briefly described.
[0337] The first display device determines that the environment of the second space is a low-light environment if the illuminance of the second space is lower than the first reference illuminance.
[0338] The first display device can obtain a face image by recognizing the face based on image information received from the second display device.
[0339] The first display device can detect an omega shape based on the acquired facial image and detect feature points of the facial image. At this time, the first display device can determine whether an omega shape has been detected in the facial image.
[0340] If the first display device determines that the omega shape is not detected and that no feature points of the facial image are detected, the first display device determines that the environment of the second space is a low-light, backlit environment, and transmits environment guide information guiding the position adjustment of the second light (290) or the position adjustment of the second image sensor (220) to the second display device (200). At this time, the second display device can display the environment guide information guiding the position adjustment of the second light (290) or the position adjustment of the second image sensor (220) through the second display unit.
[0341] When the first display device determines that an omega shape is detected and that all feature points of the first-side face image among the feature points of the left and right face images are detected, the first display device corrects the brightness of the face image, and generates feature points of the second-side face image based on the corrected image information, the feature points of the first-side face image, and the information on the central axis of the omega shape, and then identifies a detection area of a biosignal of the left and right face images based on the feature points of the first-side face image and the feature points of the second-side face image.
[0342] When the first display device determines that the omega shape is detected in a state where the illuminance of the second space is less than the first reference illuminance and that all feature points of the left and right facial images are detected, the first display device can identify the detection area of the biosignal of the left and right facial images based on the feature points of the left and right facial images.
[0343] The first display device determines whether the illuminance of the second space is less than the second reference illuminance if the illuminance of the second space is less than the first reference illuminance, and if the illuminance of the second space is determined to be less than the second reference illuminance, the first display device determines that the environment of the second space is an extremely low illuminance environment, and transmits environment guide information that guides brightness adjustment of the second lighting to the second display device (200). The second reference illuminance may be an illuminance lower than the first reference illuminance.
