[0095] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of the technical solutions of this application, but not all of them. Based on the embodiments described in this application document, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the technical solutions of this application.

[0096] The following is an introduction to some concepts involved in the embodiments of this application.

[0097] 1. In the embodiments of the present application, the term "and / or" describes the association relationship between associated objects, indicating that three relationships may exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character "three" generally indicates that the associated objects are in an "or" relationship.

[0098] 2. The term "resolution" in the embodiments of this application refers to the number of pixels in the vertical and horizontal directions, which determines the fineness of detail in a bitmap image. Generally speaking, the higher the image resolution, the more pixels it contains, the clearer the image, and the better the print quality. At the same time, it also increases the storage space occupied by the file. The resolution in the embodiments of this application is the display resolution, which is the resolution of the display when displaying an image.

[0099] 3. The term "field of view angle" in the embodiments of the present application refers to the angle formed by the two edges of the maximum range of the image of the target object that can pass through the lens of the optical instrument, with the lens of the optical instrument as the vertex. The size of the field of view angle determines the field of view of the optical instrument. The larger the field of view angle, the larger the field of view and the smaller the optical magnification. In layman's terms, the target object will not be included in the lens if it exceeds this angle. The vertical field of view angle in the embodiments of the present application is the field of view of the optical instrument in the vertical direction, such as the field of view of the camera in the present application in the vertical direction.

[0100] The following is a brief introduction to the design concept of the embodiment of this application:

[0101] With the rapid development of artificial intelligence technology, smart mirrors are becoming more and more popular as one of the smart display devices. In addition, smart mirrors can customize personalized functions based on user characteristics. Generally, collecting user facial data through cameras is the most common way to obtain user characteristics.

[0102] In related technologies, when cameras are used to collect user facial data, different users have different ages and heights, and the camera is generally fixed in position. This can lead to the problem of users of different heights not being able to display their entire faces within the same fixed area when using the camera for facial image capture. To address this issue, the main method is to manually adjust the distance between the user and the camera to display the entire facial area. However, this method prevents users of different heights from displaying their entire facial images within the fixed display area, affecting detection effectiveness.

[0103] In view of the above problems, the embodiments of the present application propose an image display device, method, and storage medium. In particular, the embodiments of the present application determine the pixel ratio of the target part of the target object in the display interface by obtaining the object portrait information of the target object, and then determine the display position of the target part of the target object in the display interface based on the pixel ratio. Finally, the target part image of the target object is displayed on the display interface. This method adapts the display of the target part image to different users, so that different users can comfortably see the target part image on the mirror, which can ensure that the user's target part image is fully displayed while improving image display efficiency.

[0104] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application can be combined with each other if there is no conflict.

[0105] The following describes the embodiments of the present application in detail by taking a smart mirror as an example of an image display device.

[0106] Figure 1 The following is an exemplary block diagram of the hardware configuration of an image display device provided by an embodiment of the present application. Figure 1 As shown, the smart mirror 100 includes a processor 110 , a detector 120 , a communication interface 130 , a display screen 140 , a user input / output interface 150 , a memory 160 , and a power supply 170 .

[0107] Processor 110 includes a CPU 111, RAM 112, ROM 113, a graphics processor 114, a communication interface 115, and a communication bus.

[0108] ROM 113 is used to store various system startup instructions. For example, upon receiving a power-on signal, the smart mirror 100 starts up, and the CPU 111 executes the system startup instructions in ROM, copying the operating system stored in memory 160 to RAM 112 to start running the operating system. After the operating system is started, the CPU 111 copies various application programs from memory 160 to RAM 112, and then starts running the various application programs.

[0109] The graphics processor 114 is used to generate various graphical objects, such as icons, operation menus, and graphics displayed in response to user input commands. It includes an operator, which receives various interactive commands from the user, performs operations, and displays various objects based on display attributes. It also includes a renderer, which generates various objects based on the output of the operator and renders the results for display on the display screen 140.

[0110] The CPU processor 111 is configured to execute operating system and application instructions stored in the memory 160 and execute various applications, data, and content according to various interactive instructions received from external input, so as to ultimately display various graphic contents.

[0111] In some exemplary embodiments, the CPU processor 111 may include multiple processors. The multiple processors may include a main processor and multiple or one sub-processors. The main processor is used to perform certain operations of the smart mirror 100 in pre-power-on mode and / or display images in normal mode. The multiple or one sub-processors are used to perform certain operations in states such as standby mode.

[0112] The detector 120 is used by the smart mirror 100 to collect signals from the external environment or external interactions.

[0116] The smart mirror 100 can establish control signal and data signal transmission and reception with an external control device or content providing device through the communication interface 130 .

[0117] Display screen 140 includes a touchscreen display component for presenting images and a driver component for driving the image display. The displayed image content may be image content processed by processor 110, or may be various image content received from a network server via a network communication protocol, or various image content generated in response to a user's touch operation. The touchscreen display may be used.

[0118] In addition, the display screen 140 displays a user control UI interface generated in the smart mirror 100 and used to control the smart mirror 100 .

[0119] The user input / output interface 150 is used to receive the user's input signal and then send the received user's input signal to the processor 110, including the voice device (( Figure 1At least one of the other input interfaces (not shown in the figure, such as a microphone) can be used. For example, the user can implement the user command input function through voice, touch and other actions, and the input interface converts the received analog signal into a digital signal, and the digital signal into a corresponding command signal, and sends it to the processor 110. The user output interface outputs the user command received by the user input interface to the processor 110, or outputs the image processed by the processor 110. Here, the user output interface may include an LED interface and a display screen 140 for outputting images. For example, the user output interface receives the output signal processed by the processor 110, and displays the output signal in the form of an image on the display screen 140.

[0120] For example, the user inputs a user command through a touch screen or a voice device, the user input interface is based on the user input, and the display screen 140 responds to the user input through the processor 110.

[0121] In some embodiments, the user may input a user command through a graphical user interface (GUI) displayed on the display screen 140 , and the user input interface receives the user input command through the graphical user interface (GUI).

For example, the various software modules stored in memory 160 include a basic module, a detection module, a display control module, and a communication module.

[0124] The basic module is a low-level software module used for signal communication between various hardware components in the smart mirror 100 and for sending processing and control signals to upper-level modules. The detection module is a management module used to collect various information from various detectors or user input interfaces, perform digital-to-analog conversion, and analyze and manage information. The display control module is a module used to control the display screen 140 to display image content, and can be used to play multimedia image content and UI interface information. The communication module is a module used for control and data communication with external devices.

[0125] At the same time, the memory 160 can also be used to store received external data and user data, images in various user interfaces, visual effect images, etc.

The camera 302 is used to capture user body images and can be an RGB camera.

[0140] The following combination Figure 3BA smart mirror according to an embodiment of the present application is briefly described. The smart mirror is 180.62 cm tall and 65.32 cm wide. Its four corners are arcs with a radius of 1.11 cm. The display screen is 94.34 cm long and 55.35 cm wide. The cameras are fixed in position, with camera 1 located 170 cm above the ground and camera 2 located 90 cm above the ground.

[0141] It should be understood that Figure 3A or Figure 3B is only an example, and the display device may have more Figure 3A The more or less components shown in the figure can be combined with two or more components, or can have different component configurations. The various components shown in the figure can be implemented in hardware, software, or a combination of hardware and software including one or more signal processing and / or application specific integrated circuits.

[0142] In an optional embodiment, a 3D camera can be used to capture an image of a target part of a target object to obtain an image of the target part. The target part can be a face (human face), face + neck, etc. The face is mainly used as an example for illustration. The specific acquisition process is as follows:

[0143] Figures 4A to 4C The following is a schematic diagram of the display interface of several facial images provided in the embodiment of the present application. Figure 4A As shown, first the smart mirror display interface shows "Please face the camera for facial capture", and after obtaining the user's portrait information through the 3D camera, it switches to Figure 4B The page shown in the figure, the smart mirror display interface shows "Face collection...", the smart mirror's internal processor calculates the display position of the user's face on the display interface, and switches to the following Figure 4C As shown in the page, the smart mirror display interface shows the user's facial image after height adaptation, and the display interface shows "Face collection completed". The user can choose "Confirm" to complete the facial collection, or choose "Retake" to continue facial collection until they are satisfied with the displayed facial image.

[0144] FIG5 exemplarily shows a schematic diagram of a display interface for body data measurement provided by an embodiment of the present application. After completing the facial image acquisition shown in FIG4 , the smart mirror can also provide body data measurement through the RGB camera, such as measurement of body data such as shoulder width, waist circumference, and hip circumference. Figure 5A First, the smart mirror display interface will show "Please face the mirror, stand in the circular area below, and wear light-colored clothes when collecting data". The circular area is the recommended photo area. After taking a photo of the front of the body with the RGB camera, it will switch to the following Figure 5BThe page shown in the figure shows "Please turn sideways" on the display interface. Take a photo of the side of your body. After taking the photo, switch to the Figure 5C The page shown in the figure shows "Model Generating" on the display interface. After the user's body data is generated by taking photos of the front and side of the body, the interface switches to the following Figure 5D The page shown shows the measured body data such as weight, height, shoulder width, etc. The user can click "Done" to end the measurement, or click "Measure with a ruler" to measure again.

[0145] In an optional embodiment, the processor is also used to determine a recommended photographing area based on the parameters of the camera, wherein the parameters of the camera include at least: the installation height of the camera relative to the device and the field of view angle corresponding to the camera; the recommended photographing area is a photographing area that makes the image of the target part captured by the camera meet the preset standards.

[0146] In the embodiment of the present application, the vertical field of view is mainly used as an example for illustration. The recommended license plate area is a region where the entire human body can be photographed, and the image taken is clear, for example Figure 6 As shown, the recommended photo-taking area is within 1.2-1.3 meters.

[0147] Figure 6 The following is a schematic diagram of a recommended photo area provided by an embodiment of the present application. When the camera is 170-190 cm from the ground and the vertical field of view is 120°, the recommended photo area is within 1.2-1.3 meters from the camera in the horizontal direction. When the camera is 170 cm from the ground, that is, the length of the dotted part of the right triangle formed is 170 cm, and the vertical field of view is 120°, according to the tangent function, the distance from the camera to the ground is the horizontal distance from the camera to the closest point where the entire human body can be photographed. times, the horizontal distance from the camera to the recommended photo area can be calculated as When the camera is 190 cm from the ground, that is, the length of the dotted part of the right triangle is 190 cm, and the vertical field of view is 120°. According to the tangent function, the distance from the camera to the ground is the horizontal distance from the camera to the recommended shooting area. times, we can calculate the horizontal distance from the camera to the closest point that can capture the entire human body: Therefore, the closest distance area for capturing the entire human body is within 0.98-1.1 meters from the camera in the horizontal direction. That is to say, if you want to capture the entire human body, you should stand within 0.98-1.1 meters. However, this is not the best position. Referring to the best position for portrait proportions, it is 1.2-1.3 meters. Therefore, the recommended shooting area is within 1.2-1.3 meters from the camera in the horizontal direction.

[0148] Figure 7The following is an exemplary flowchart of an image display method provided by an embodiment of the present application. The method can be applied to facial image display, and the method includes:

[0149] Step S701: Obtain object portrait information of the target object.

[0150] In an optional embodiment, the object portrait information includes at least the height information and age information of the target object, and the object portrait information of the target object is obtained by any of the following methods:

[0151] Detect the target object's height and age information through image recognition algorithms;

[0152] The user inputs height information and age information;

[0153] Get the user's height and age information stored in advance from the background.

[0154] Step S702: Determine the pixel ratio of the target part of the target object in the display interface according to the object portrait information, and determine the display position of the target part of the target object in the display interface according to the pixel ratio.

[0155] In an optional embodiment, the smart mirror can determine the target part ratio corresponding to the age range to which the age information belongs based on a preset correspondence, where the preset correspondence is used to represent the target part ratio corresponding to different age ranges, and the target part ratio is used to represent the ratio of the target part height to the body height. Based on the target part ratio and the body height information, the height of the target part of the target object is determined, and based on the resolution of the display interface and the target part height, the pixel ratio of the target part area of ​​the target object on the display interface is determined.

[0156] Specifically, the smart mirror determines the mapping pixel value based on the resolution of the display interface, where the mapping pixel value represents the number of pixels displayed per unit height; and the product of the mapping pixel value and the height of the target part is used as the pixel ratio of the target part of the target object in the display interface.

[0157] The ratio of a person's head to their height is age-related, and the relationship between them forms a preset correspondence. Generally speaking, the length of an adult's head is about 1 / 8 of their height (over 20 years old), 1 / 7 for young people aged 7-20, 1 / 6 for teenagers aged 13-16, 1 / 5 for teenagers aged 9-12, 1 / 4 for elementary school students aged 7-8, 1 / 3 for children aged 4-5, and 1 / 2 for infants.

[0158] Assume that a 25-year-old user, 160 cm tall, stands in the recommended photo area in front of the smart mirror provided in an embodiment of the present application. The user's facial information is first captured by the camera, and then analyzed using an image recognition algorithm to detect the user's height and age. Based on the preset correspondence, the head height of a 25-year-old adult accounts for approximately 1 / 8 of the height, so the user's head height can be calculated to be 20 cm. When the display interface resolution is 300 dpi (dots per inch), that is, 300 pixels are displayed per inch, after converting inches to centimeters, it can be determined that 118 pixels are displayed per centimeter. Multiplying the user's head height by the number of pixels displayed per centimeter, we can determine that the user's head accounts for 2360 pixels on the display interface.

[0159] In an optional embodiment, the display position of the target part of the target object in the display interface is determined based on the height information and pixel ratio of the target object. The display position of the target part of the target object in the display interface can be determined in the following two ways:

[0160] Method 1: Determine the target part display area corresponding to the target object in the display interface based on the height information of the target object; determine the display position of the target part of the target object in the display interface based on the target part display area and the pixel ratio;

[0161] Specifically, the user's height can be mapped to several intervals corresponding to the display interface. For example, the user's height can be divided into two intervals, 150-165 cm and 166-180 cm, and the display interface can be divided into two intervals, low and high. When the user's height falls within the 150-165 cm interval, the user's facial image is displayed in the lower half of the display interface. When the user's height falls within the 166-180 cm interval, the user's facial image is displayed in the upper half of the display interface. Furthermore, based on the pixel ratio of the user's face, the corresponding display position of the user's face in the upper / lower half is determined, wherein the center of the face is located at the center of the upper / lower half. Based on the pixel ratio of the face, the radius of the circular display area of ​​the face is determined to be half of the facial pixel ratio.

[0162] Method 2: Determine the display position of the target part of the target object in the display interface based on the height ratio and pixel ratio corresponding to the target object, where the height ratio is the ratio of the target object's height to the height of the display screen, which is determined based on the target object's height information.

[0163] Specifically, when the user's height is 160 cm and the height of the display screen is 80 cm, the corresponding height ratio of the user is 1 / 2, the display position of the user's facial image is that the center of the user's facial image is 40 cm from the display screen, and the radius of the facial circular display area is half of the facial pixel ratio.

[0164] Step S703: displaying the target part image of the target object on the display interface according to the display position.

[0165] Specifically, according to the display position determined in step 702, the user's facial image is displayed on the display interface, such as Figure 3B shown.

[0166] In an optional embodiment, the recommended photographing area is determined based on camera parameters, wherein the camera parameters include at least the camera's installation height relative to the device and the camera's corresponding field of view. The recommended photographing area is a photographing area where the image of the target part captured by the camera meets a preset standard.

[0167] Specifically, the recommended photo area is the position that can capture the entire body and is closest to the camera. When the camera is installed at a height of 1.7 meters relative to the device and the corresponding vertical field of view angle is 120°, it can be calculated that the recommended photo area at this time is 0.98 meters away from the camera; when the camera is installed at a height of 1.9 meters relative to the device and the corresponding vertical field of view angle is 120°, it can be calculated that the recommended photo area at this time is 1.1 meters away from the camera.

[0168] In an optional embodiment, when there are multiple target objects, the pixel ratio corresponding to each of the multiple target objects can be determined, and the maximum pixel ratio among the multiple target objects can be obtained by comparison. According to the maximum pixel ratio, the display position of the target part of the corresponding target object in the display interface is determined, and the target part image of the target object is displayed on the display interface.

[0169] Specifically, assuming that two users are standing in front of the smart mirror at the same time and the target part is the face, the object portrait information of each user is first obtained, and then the pixel ratio of each user is determined based on their respective object portrait information. The pixel ratios of the two users are compared, and the user with the larger pixel ratio is determined. The display position on the display interface is determined based on the pixel ratio of this user, and the facial image of this user is displayed on the display interface.

[0171] S801: The smart mirror obtains the height and age information input by the user;

[0172] S802: The smart mirror calculates the facial pixel ratio of the user based on the acquired height and age information;

[0173] S803: The smart mirror determines the display position of the user's face on the smart mirror display screen based on the facial pixel ratio;

[0174] S804: The smart mirror dynamically displays the facial image collected by the user when the user is in the recommended photo-taking area at the display position.

[0176] S901: The smart mirror camera obtains the user's facial information, and then analyzes the collected facial information through an image recognition algorithm to detect the user's height and age information;

[0177] S902: The smart mirror determines the facial pixel ratio of the user based on the user's height information and age information;

[0178] S903: The smart mirror determines whether it is a single user's facial pixel ratio. If so, execute step S905; otherwise, execute step S904;

[0179] S904: The smart mirror determines the largest pixel proportion among the multiple pixel proportions;

[0180] S905: The smart mirror determines the display position of the user's face on the smart mirror display screen based on the facial pixel ratio;

[0181] S906: The smart mirror dynamically displays the facial image collected by the user when the user is in the recommended photo-taking area at the display position.

[0206] It should be noted that, in addition to the image display devices, methods, and apparatuses listed above, the present application also provides another image display device, method, and apparatus.

[0207] Still based on image display devices Figure 3A Taking the smart mirror shown as an example, the display screen of the smart mirror in the embodiment of the present application is used to display images on the display interface, and the display screen has a mirror function.

[0208] When target objects of different heights use the display device, since the display screen has a height adaptation function, the display positions of the corresponding target part images are different for two target objects of different heights.

[0209] For example Figure 11 As shown, Figure 11 The following is a flowchart of an image display method provided by an embodiment of the present application, which can be applied to facial image display and includes the following steps:

[0210] S1101: In response to a trigger request of a first object, display an image of a target part of the first object at a first display position in a display interface;

[0211] The first display position may be determined based on the object portrait information of the first target object. For a specific determination method, please refer to the above embodiment.

[0212] like Figure 12A As shown, it is a display position diagram of an image display method provided in some embodiments of the present application. Figure 12AShown in FIG. 1 is a user with a height of 170 cm and the corresponding display position of the facial image when the facial image is collected.

[0213] S1102: In response to a trigger request of the second object, display an image of a target part of the second object at a second display position in the display interface.

[0214] The second display position may also be determined based on the object portrait information of the second target object. For a specific determination method, please refer to the above embodiment, and any repetitions will not be repeated. If the height information in the object portrait information of the first object and the second object is different, that is, if the heights of the first object and the second object are different, the first display position and the second display position will also be different.

[0215] like Figure 12B As shown, it is a display position diagram of another image display method provided in some embodiments of the present application. Figure 12B Shown in FIG. 1 is a user with a height of 160 cm and the corresponding display position of the facial image when the facial image is collected.

[0216] Combine Figure 12A and Figure 12B It can be seen that when an image display method provided in the present application is applied to a smart mirror, the facial images of users of different heights are displayed at different positions in the smart mirror. The facial image of a user with a taller height can be displayed at a higher position in the smart mirror, and the facial image of a user with a shorter height can be displayed at a lower position in the smart mirror.

[0217] In the above technical solution, the display area can be adjusted according to the user's object portrait information, and the target part image can be adapted for different users, so that different target objects can comfortably see the target part image on the mirror without the need for manual adjustment by the user. This can ensure that the user's target part image is fully displayed while improving the image display efficiency.
