[0029] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0031] Considering that the related art only statically displays fixed picture content on the display screen, which is not very attractive to users and the user's visual experience is not good, in order to improve this problem, the embodiments of the present disclosure provide an image display method, device, equipment and medium, which are specifically explained below.

[0032] Figure 1 This is a flow chart of an image display method provided in an embodiment of the present disclosure. The method can be executed by an image display device, wherein the device can be implemented by software and / or hardware, and can generally be integrated in a controller (or processor) of an electronic device. Therefore, it can also be said that the image display method is applied to an electronic device. In the embodiment of the present disclosure, the electronic device can be configured with a display screen. Figure 1 As shown, the method mainly includes the following steps S102 to S106:

[0033] Step S102, when the target person is detected to be moving, the movement information of the target person is obtained. The movement information includes the movement direction and the movement distance.

[0034] In actual applications, electronic devices can collect environmental data within a specified spatial range in front of a display screen through preset sensors, and then use human body detection technology to analyze the environmental data, and further obtain the movement information of the target person when the target person is detected.

[0035] Among them, the preset sensor can be one or more sensors such as a camera, a distance sensor, an infrared sensor, a laser radar, etc. The embodiment of the present disclosure does not limit the type of preset sensors. Specifically, the sensor that can collect environmental data in front of the display screen can be flexibly selected according to the specific type of electronic equipment and the required cost. The environmental data can be an image, which can be a two-dimensional image or a depth image, or a sensor signal, point cloud data, etc. The form of the environmental data depends on the type of the preset sensor. Through human body detection technology, people can be detected from environmental data. In some implementation examples, all detected people can be used as target people without paying attention to the identity of the person; in other implementation examples, people who meet the conditions among all detected people can be used as target people, such as only people whose identities are pre-entered can be used as target people, that is, only people whose identities are pre-entered have the right to view the image in the screen interface. Specifically, the above method can be flexibly selected according to actual needs. For example, if the electronic device is an electronic billboard, there is no need to pay attention to the identity of the person; if the electronic device is a door access control or a home appliance, there is no need to pay attention to the identity of the person, or the image can be displayed only for the preset legitimate users.

[0036] After detecting a person, the environmental data can be further analyzed to obtain the movement information of the person. For example, if the designated sensor is a depth camera and the environmental data is a depth image, the movement information of the person can be obtained based on the depth image data collected in multiple frames. For example, if the designated sensor is multiple distance sensors and the environmental data is a distance signal, the movement information of the person can be obtained based on the distance signals collected by multiple distance sensors. The above are all exemplary descriptions. In actual applications, other methods can also be used to obtain movement information, which are not limited here.

[0037] Step S104: determining display adjustment information of the target image displayed on the screen interface according to the movement information.

[0038] In the embodiment of the present disclosure, the initial size of the target image used is larger than the size of the screen interface, so that the screen area where the target image is initially displayed in the screen interface is a local area of ​​the target image. In practical applications, an image of a specific size can be pre-made as the target image, or a conventional image can be used, and then the size of the conventional image can be adjusted to obtain a target image of a specific size. For example, the original image to be displayed can be obtained, and the size of the screen interface can be obtained; wherein the screen interface is the interface of the display screen; then the size of the original image is adjusted according to the size of the screen interface, so that the size of the adjusted original image is larger than the size of the screen interface; finally, the original image after the size adjustment is used as the target image, and the size of the adjusted original image is used as the initial size of the target image. The embodiment of the present disclosure does not limit the specific size of the image, such as, the initial length of the target image can be N1 times the length of the screen interface, and the initial width of the target image can be N2 times the width of the screen interface, and N1 and N2 are both values ​​greater than 1. Through the above method, a target image whose size is larger than the screen interface can be obtained conveniently and quickly. The embodiment of the present disclosure does not limit the content of the target image, and the required target image can be flexibly selected depending on the image display requirements of the electronic device. For example, the target image displayed on an electronic billboard can be an advertising image.

[0039] The target image initially only displays a local area screen on the screen interface. The embodiment of the present disclosure can determine the display adjustment information of the target image according to the movement information, so as to dynamically adjust the screen content displayed by the target image on the screen interface according to the display adjustment information. That is, the relative position between the target person and the display screen changes, and the screen content displayed on the screen interface seen by the target person also changes accordingly. Exemplarily, the display adjustment information of the target image includes the scaling information of the target image and the position change information of the center point of the display area of ​​the target image on the screen interface. It should be noted that the position change information of the center point of the display area is the position change information of the center point of the display area in the target image, such as, the current display area of ​​the target image on the screen interface is area A in the target image, and the center point of area A is located at point A in the target image. The position change information of the center point of the current display area (point A) and the center point of the target display area to be displayed (assuming point B) is determined according to the movement information, so that the specific position of point B in the target image can be obtained based on the position change information, and point B is further moved to the center point of the screen interface. At this time, the area displayed on the screen interface is the target display area.

[0040] Exemplarily, when a user (the target person can be regarded as a user) approaches the display screen, the target image (hereinafter referred to as the image) can be enlarged so that the user can see clearer details of the local image. When the user moves backward away from the display screen, the image can be reduced so that the user can see more image content. For example, when the user walks in a direction parallel to the display screen (such as horizontally moving to the left), the display area of ​​the image on the display screen also moves accordingly, which can be figuratively understood as the image moving to the right relative to the display screen, so that the image of the left area can be displayed on the display screen. Before that, only the central area of ​​the image is displayed on the display screen, and the left area is not visible. The above method can give the user a feeling that the image moves with the person. The above is only an exemplary description and should not be regarded as a limitation. When the user moves obliquely relative to the display screen, the image can be scaled and the position of the center point of the display area of ​​the image in the image can be adjusted at the same time. In actual applications, the specific scaling information of the image and the position change information of the center point of the display area of ​​the image on the display screen can be determined according to the user's movement information, so that the display area of ​​the image on the display screen can be reasonably adjusted later, giving the user a feeling that the image screen moves dynamically and adjusts as the user moves.

[0041] Step S106, according to the display adjustment information of the target image, adjust the current display area of ​​the target image on the screen interface to the target display area; wherein the current display area and / or the target display area is a local area where the target image is displayed on the screen interface.

[0042] The current display area is the display area before the target object moves, and the target display area is the display area re-determined according to the movement information of the target object. In some embodiments, when the target person is not detected, the screen is kept in a dormant state, and the screen can display a black screen or a screen saver image; when the target person is detected for the first time, the display screen can be awakened, and a local area (such as the central area) of the target image can be displayed on the display screen. The area displayed at this time is also the current display area. When the target person moves, the display adjustment information of the target image can be determined according to the movement information, and the current display area of ​​the target image on the screen interface is adjusted to the target display area according to the display adjustment information. The above processes are all dynamic adjustment processes, such as when the target person (which can be regarded as the user) is located at the spatial area X1 position in front of the display screen, the electronic device confirms that the user is detected for the first time, and the image partial screen A is displayed to the user at this time, and the partial screen A is used as the current display area; after that, it is detected that the user moves from the X1 position to the X2 position, and the image partial screen B is displayed to the user at this time, and the partial screen B is the target display area. If it is detected that the user continues to move from position X2 to position X3, the partial image B can be used as the current display area, and the partial image C that the user can view at position X3 can be used as the target display area. The above process is a dynamic process. Every time the user moves, the display area of ​​the target image on the screen interface can be adjusted by referring to steps S102 to S106.

[0043] In addition, when the target person is detected and does not move, the current display area can be continuously displayed on the screen interface, and the display area screen of the image is adjusted accordingly only when the person moves.

[0044] In summary, in the disclosed embodiment, since the initial size of the target image is larger than the screen interface size, the above method can display a local area of ​​the target image on the screen interface, and dynamically adjust the area of ​​the target image displayed on the screen interface according to the movement information of the target person, not only presenting a dynamic picture effect to the user, but also the dynamically displayed picture is related to the user's own movement, which can better attract users and effectively improve the user's visual experience. In addition, the disclosed embodiment can achieve a dynamic picture effect with only one image, no longer a fixed static display image, and can achieve an effect of interacting with the user. Compared with the existing technology that requires virtual engines to achieve the effect of interacting with the user, the disclosed embodiment is easier to implement and requires lower costs and requires less memory.

[0045] Further, the embodiment of the present disclosure provides an implementation of the above step S104, which can be implemented by referring to the following steps A to C:

[0046] Step A, according to the moving direction and the moving distance, obtain the vertical displacement component of the target person in the direction perpendicular to the screen interface, and the horizontal displacement component of the target person in the direction horizontal to the screen interface. It is understandable that the user can move in any direction in front of the display screen, but any direction can be decomposed into a direction perpendicular to the display screen and a direction horizontal to the display screen, and this decomposition method is more convenient for subsequent processing.

[0047] Step B, determining the scaling information of the target image based on the vertical displacement component. As mentioned above, when the user approaches the display screen, the target image (hereinafter referred to as the image) can be enlarged so that the user can see clearer local picture details. When the user moves back away from the display screen, the image can be reduced so that the user can see more image content. In some embodiments, the distance between the user and the display screen has a corresponding relationship with the scaling ratio of the image, such as, the closer the user is to the display screen, the greater the image magnification ratio value, and the farther the user is from the display screen, the greater the image reduction ratio value. In some embodiments, the scaling information includes a scaling processing method and a scaling ratio; on this basis, exemplarily, the above step B can be implemented specifically with reference to the following steps B1 and B2:

[0048] Step B1, based on the displacement direction in the vertical displacement component, determine the scaling processing mode of the target image; the scaling processing mode includes: size reduction processing, size enlargement processing or size unchanged.

[0049] If the vertical displacement direction indicates that the target person is moving toward the display screen (that is, approaching the screen interface), the scaling processing method is size enlargement processing; if the vertical displacement direction indicates that the target person is moving away from the display screen, the scaling processing method is size reduction processing; if the vertical displacement direction indicates that the vertical distance between the target person and the display screen remains unchanged (the vertical displacement component is 0), the scaling processing method is to keep the size unchanged.

[0050] Step B2, determining the image scaling ratio of the target image based on the displacement length in the vertical displacement component.

[0051] In some embodiments, the displacement length is positively correlated with the zoom ratio. The larger the displacement length, the larger the zoom ratio, so as to present a visual effect that meets the user's perception. As the user gets closer to the display screen, the magnification ratio of the target image becomes larger and larger, and the user can gradually see the details of the target image clearly. As the user moves further and further away from the display screen, the reduction ratio of the target image becomes larger and larger, and the user can gradually see more and more screen content of the target image completely and comprehensively, until all the screen content of the target image is displayed on the screen interface.

[0052] Step C, determining the position change information of the center point of the display area of ​​the target image on the screen interface based on the horizontal displacement component. In some embodiments, the position change information includes the relative position relationship and distance between the center point of the current display area and the center point of the target display area in the target image; on this basis, illustratively, the above step C can be implemented specifically with reference to the following steps C1 and C2:

[0053] Step C1, based on the displacement direction in the horizontal displacement component, determine the relative position relationship between the center point of the current display area and the center point of the target display area in the target image. For example, when the displacement direction indicates that the target person moves to the left relative to the display screen, it can be determined that the center point of the target display area is located to the left of the center point of the current display area in the target image. Conversely, when the displacement direction indicates that the target person moves to the right relative to the display screen, it can be determined that the center point of the target display area is located to the right of the center point of the current display area in the target image.

[0054] Step C2, based on the displacement length in the horizontal displacement component, determine the distance between the center point of the current display area and the center point of the target display area in the target image. In some implementation examples, the displacement length is positively correlated with the distance, such as the greater the user's horizontal displacement, the greater the distance between the center point of the current display area and the center point of the target display area in the target image.

[0055] Through the above steps A to C, the adjustment information of the image displayed on the display screen can be accurately and reliably determined according to the movement of the person, so as to reasonably and dynamically adjust the image display area and provide the user with a better visual experience.

[0056] Based on the above, illustratively, step S106 can be implemented by referring to the following steps (1) to (2):

[0057] Step (1), determining the center point of the target display area in the target image according to the position change information and the position of the center point of the current display area in the target image.

[0058] It can be understood that after the position of the center point of the current display area in the target image is known, the position of the center point of the current display area in the target image can be obtained based on the position change information of the center point of the display area, which can be specifically represented in the form of point coordinates.

[0059] Step (2), adjusting the size of the target image according to the image scaling information, and moving the center point of the target display area to the center position of the screen interface so that the screen interface displays the target display area.

[0060] The above-mentioned image size adjustment process and center point movement process can be performed simultaneously, or the size can be adjusted first and then the center point; or the center point can be adjusted first and then the size, and there is no restriction here. When the image size is finally adjusted and the center point of the target display area is moved to the center position of the screen interface, the image display area presented on the screen interface is the target display area. In this way, the user can be presented with the effect that the image screen is dynamically adjusted as the user moves.

[0061] To facilitate understanding of the above contents provided by the embodiments of the present disclosure, firstly, Figure 2 The front view of an image display scene shown in FIG. 1 is taken as an example that the initial length and width of the target image are twice the length and width of the display screen, and the target image is a 2D image. The target character is located in the space in front of the display screen and can move in any direction. Figure 2 8 directions are schematically given in the figure. Specifically, D1 indicates that a person approaches the display screen in a direction perpendicular to the display screen, D5 indicates that a person moves backwards away from the display screen in a direction perpendicular to the display screen, D3 indicates that a person moves to the right in a direction horizontal to the display screen, D7 indicates that a person moves to the left in a direction horizontal to the display screen, and D2, D4, D6 and D8 indicate that a person moves obliquely relative to the display screen, and the moving direction has a certain inclination angle with the horizontal direction or the vertical direction. In practical applications, the display adjustment information of the 2D image (such as the scaling processing method, scaling ratio, and the position change information of the center point of the display area, etc.) can be determined according to the moving direction of the person, so that the partial picture of the 2D image displayed on the display screen will change dynamically as the person moves, giving the person a visual perception that the image moves with him.

[0062] exist Figure 2 Based on this, we further provide Figure 3 to Figure 5 The image display adjustment diagram shown in FIG. Figure 3 As shown in FIG. 1 , it indicates that when a person approaches the display screen vertically (ie, the person moves along the direction D1), the 2D image (target image) displayed on the display screen will be enlarged to show the person clear image details; and as shown in FIG. Figure 4 As shown in FIG. 1 , it indicates that when a person moves to the left along the direction horizontal to the display screen (that is, the person moves along the direction D7), the 2D image will move to the right. At this time, the previously invisible left area of ​​the 2D image can be moved to the display screen, and the user can gradually see the image content of the left area of ​​the 2D image that has not been seen before while moving. Figure 5As shown, it is shown that when a person moves to the right along the direction horizontal to the display screen (that is, the person moves along the D3 direction), the 2D image will move to the left. At this time, the previously invisible right area in the 2D image can be moved to the display screen, and the user can gradually see the image content of the right area of ​​the 2D image that has not been seen before while moving. It should be noted that if the person moves obliquely relative to the display screen (that is, the person moves along the D2, D4, D6 and D8 directions), the 2D image can be scaled and moved at the same time to adjust the image content of the 2D image displayed on the display screen.

[0063] For easier understanding, see Figure 6 A schematic diagram of an image area is shown, which roughly divides the screen area of ​​the image to be displayed (i.e., the target image) into 9 areas for description. For example, when the user (i.e., the target person, which can be regarded as the image viewer of the display screen) is initially sensed, the central area of ​​the image can be displayed on the interface of the display screen (for ease of understanding, it is assumed that the interface size of the display screen is equal to the size of the central area), and the user cannot see the other eight peripheral areas at this time. When the user moves along the D1 direction, the image is enlarged, and the interface of the display screen will enlarge and display a partial area of ​​the central area, and the user will not see the complete central area at this time; when the user moves along the D5 direction, the image is reduced, and the interface of the display screen will display the screen content of the other eight peripheral areas, and as the user moves further and further away from the display screen, the screen content of the other eight peripheral areas displayed on the interface of the display screen will increase, until all the screen content of the image is displayed on the interface of the display screen. When the user moves along the D3 direction, the screen content of the right middle area will gradually be displayed on the display screen interface. Assuming that the display screen interface finally displays the right middle area, and assuming that the size of the right middle area is equal to the size of the screen interface, the center point of the display area will move from the center point of the center area of ​​the image to the center point of the right middle area of ​​the image; correspondingly, when the user moves along the D7 direction, the screen content of the left middle area will gradually be displayed on the display screen interface, which will not be repeated here. When the user moves along the D2, D4, D6 or D8 directions, the image will be scaled and the center point of the display area will be moved at the same time, so as to adjust the screen content displayed on the display screen interface.

[0064] It should be noted that Figure 6The image is roughly divided into 9 areas for the convenience of description, which should not be regarded as a limitation. In actual applications, the image may not be divided into zones, and it should not be understood that each zone will be displayed separately on the screen interface. In fact, multiple zones can be displayed on the screen interface at the same time, such as the screen interface showing part of the central area, part of the upper middle area, part of the middle right area, and part of the upper right area. Moreover, in actual applications, as the character moves, the image changes dynamically and gradually, and the character can watch the dynamic adjustment process of the image while moving.

[0065] Based on the above, the present disclosure also provides an image display method, which can be found in Figure 7 The flowchart of an image display method shown in FIG. 1 mainly includes the following steps:

[0066] Step S702, determine whether the target person is detected; if yes, execute step S704, if not, continue to execute step S702.

[0067] Step S704, determine whether the target person moves, if yes, execute step S706, if not, continue to execute step S710.

[0068] In actual applications, environmental data of the specified space in front of the display screen (such as environmental images, point cloud data, detection signals, etc.) can be obtained in real time, and whether the target person is detected can be determined based on the environmental data, and whether the target person moves can be determined based on the continuously collected environmental data.

[0069] Step S706, obtaining movement information of the target person, and determining display adjustment information of the target image displayed on the screen interface according to the movement information.

[0070] Step S708, adjusting the current display area of ​​the target image on the screen interface to the target display area according to the display adjustment information of the target image, and then executing step S702 again.

[0071] That is, it is possible to continue to detect whether the target person is still in front of the display screen, and to determine whether the target person has moved. The target person may be any person, or a person of a specified identity, etc., and is not limited here.
