Summary of the invention

[0004] The embodiments of the present invention provide a video screen display method, device, electronic device and readable storage medium, which can solve the problem that when a user makes a video call or shoots a video while walking, because the user's line of sight is focused on the video interface of the electronic device, the user cannot see the obstacles in front of him, which may easily endanger his personal safety.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0025] The video image display method provided by the embodiment of the present invention can be applied to at least the following application scenarios, which are described below.

[0026] like Figure 1 As shown, when a user uses an electronic device to make a video call, the front camera of the electronic device is aimed at himself to shoot, and accordingly, the other party's video screen is displayed on the user's electronic device interface to realize the video call between the two parties. Since the display screen of the electronic device is opaque, and when the user makes a video call, the user's line of sight is often focused on the display screen of the electronic device, and the objects in the real world behind the electronic device cannot be seen. Therefore, when the user is walking and making a video call, it is easy to bump into a concave obstacle on the road, affecting personal safety.

[0027] In addition, when users use electronic devices to shoot videos (such as users use the front camera to shoot a Vlog of themselves), the user's line of sight is often focused on the video screen on the electronic device display, and it is easy to ignore things in the surrounding area, which brings certain safety hazards.

[0028] Among them, the situation where users use electronic devices to shoot videos also includes the situation where users use electronic devices to broadcast live. When users broadcast live, their sight is often focused on the live broadcast interface of the electronic device, and their attention is often focused on user comments on the live broadcast interface and their own live video screen. They cannot see things in the surrounding area, which brings security risks and affects personal safety.

[0029] In response to the problems arising in the related art, the embodiments of the present invention provide a video screen display method, device, electronic device and storage medium, which can solve the problem in the related art that when a user makes a video call or shoots a video while walking, because the user's line of sight is focused on the video interface of the electronic device, he cannot see the obstacles in front of him, which may easily endanger his personal safety.

[0030] In addition to being applicable to the above-mentioned application scenarios, the method provided by the embodiment of the present invention can also be applied to scenarios where a user ignores dangerous objects in the surrounding area when using an electronic device, thereby causing potential safety hazards.

[0031] By using the method provided by the embodiment of the present invention, when a video call or video shooting is being conducted, the video screen of the video call or video shooting is displayed on the holographic 3D smart screen, and when an obstacle is detected, the brightness of the video screen is reduced to the target brightness. Since the fan blades of the holographic 3D smart screen rotate, there is a certain degree of transparency. And the lower the brightness of the video screen, the higher the transparency. Therefore, when an obstacle is detected in front of the user, by reducing the brightness of the video screen, the transparency of the video screen can be improved, so that the user can see the obstacle in front, and then can avoid it in time to ensure the user's personal safety.

[0032] Below, the holographic three-dimensional smart screen and distance sensor appearing in this application are explained and illustrated.

[0033] The holographic 3D smart screen is also called a light emitting diode (LED) fan and a "rotating LED light bar". After the LED fan (i.e. the holographic 3D smart screen) is turned on, the blades of the LED fan begin to rotate, and while rotating, it can present a series of 3D images, which are cool and realistic. At the same time, according to the size and color of the video screen, the LED fan can hide the blades well during the rotation process.

[0034] The holographic 3D smart screen not only utilizes the hardware configuration of rotating LED, but also utilizes the visual persistence phenomenon of human eyes. In simple terms, the hardware configuration of rotating LED is to calculate the changing frequency of LED lights according to the rotation speed of the fan blades, and light up different Maipu colorful LED lights at different times to present different patterns.

[0035] Among them, the phenomenon of persistence of vision refers to that when the human eye observes the scenery, it takes a short period of time for the light signal to be transmitted to the brain nerves. After the effect of light ends, the visual image does not disappear immediately, and the human eye can continue to maintain its image for about 0.1 seconds to 0.4 seconds. This residual vision is called "afterimage", and this visual phenomenon is called "persistence of vision".

[0036] Therefore, the holographic three-dimensional smart screen can be used to display clear and smooth video images.

[0037] Based on the above application scenarios, the video picture display method provided by the embodiment of the present invention is described in detail below.

[0038] Figure 2 The present invention provides a flowchart of a method for displaying a video image.

[0039] like Figure 2 As shown, the display method may include steps 210 to 220, and the method is applied to a video screen display device, as shown below:

[0040] Step 210, when the electronic device is in a target scene, a video image corresponding to the target scene is displayed on the holographic three-dimensional smart screen, and the target scene includes a video call scene or a video shooting scene.

[0041] Step 220, when an obstacle is detected, the display brightness of the video image is reduced to a target brightness.

[0042] In the video screen display method provided by the embodiment of the present invention, when a video call or video shooting is in progress, the video screen of the video call or video shooting is displayed on the holographic three-dimensional smart screen, and when an obstacle is detected, the brightness of the video screen is reduced to the target brightness. Since the fan blades of the holographic three-dimensional smart screen rotate, there is a certain degree of transparency. And the lower the brightness of the video screen, the higher the transparency. Therefore, when an obstacle is detected in front of the user, by reducing the brightness of the video screen, the transparency of the video screen can be improved, so that the user can see the obstacle in front, and then can avoid it in time to ensure the personal safety of the user.

[0043] The contents of step 210 to step 220 are described below respectively:

[0044] First, step 210 is involved.

[0045] When making a video call or shooting a video, the video screen of the video call or shooting is displayed on the holographic 3D smart screen.

[0046] like Figure 3As shown, a foldable holographic 3D smart screen is installed on the back of the electronic device, which is in a folded state at ordinary times. A distance sensor can be installed at the center of the back of the foldable holographic 3D smart screen.

[0047] The holographic 3D smart screen and distance sensor are turned off when not making a video call or shooting a video. Figure 4 As shown, when a video call or video shooting is in progress, the foldable holographic 3D smart screen on the back of the electronic device changes from a folded state to an unfolded state, and the blades of the holographic 3D smart screen begin to rotate, and the video screen of the video call or video shooting is displayed on the holographic 3D smart screen. The distance sensor is also turned on accordingly to start obstacle distance measurement.

[0048] In a possible embodiment, before the above step of displaying the video picture corresponding to the target scene on the holographic 3D smart screen, the following steps may also be included:

[0049] Receive a first input from a user; in response to the first input, turn on the holographic three-dimensional smart screen.

[0050] Exemplarily, a first input from a user to the holographic 3D smart screen is received, and in response to the first input, the holographic 3D smart screen is turned on, that is, the holographic 3D smart screen is changed from a folded state to an unfolded state, so as to display video images on the holographic 3D smart screen.

[0051] Among them, the first input involved above can be the user's input to the holographic three-dimensional smart screen switch button, or the touch input on the interface of the electronic device, or the gesture input to the electronic device.

[0052] Thus, by responding to the first input of the user, the holographic 3D smart screen is restarted, so that the holographic 3D smart screen can be turned on when the user needs it, which is more in line with the user's needs and improves the user experience.

[0053] Then, step 220 is involved.

[0054] Among them, obstacles can be detected by distance sensors or by dual-camera ranging. The following are explained in turn:

[0055] First of all, a distance sensor, also called a displacement sensor, is a type of sensor that is used to sense the distance between it and an object to complete a preset function. Distance sensors can be divided into optical distance sensors, infrared distance sensors, ultrasonic distance sensors, etc. according to their working principles.

[0056] Most distance sensors used in electronic devices are infrared distance sensors, which have an infrared transmitting tube and an infrared receiving tube. They can transmit infrared rays, which are reflected by nearby objects, and then use infrared detectors to receive the intensity of the infrared rays, and calculate the distance to the object based on this.

[0057] The working principle of other types of distance sensors is roughly the same. They also judge the distance through the emission and reception of a certain substance. The emitted substance can be ultrasonic waves, light pulses, etc.

[0058] Secondly, dual-camera ranging is to use two images taken by two cameras on the electronic device to calculate the depth of field information, and then measure the physical distance between the object and the electronic device, as well as the physical size of the object.

[0059] When an obstacle is detected, the brightness of the video screen is reduced to the target brightness. The video screen with the target brightness allows the user to see the video screen displayed by the holographic three-dimensional smart screen, and also see the obstacle on the back of the electronic device, and then avoid the obstacle on the back of the electronic device.

[0060] Figure 5 As shown in the figure, when no obstacle is detected, the holographic 3D smart screen displays video picture 1. When the distance sensor detects an obstacle (seat, electric car), the brightness of video picture 1 is reduced to the target brightness to obtain video picture 2. The transparency of video picture 2 displayed by the holographic 3D smart screen is significantly improved, and users can see the real-world obstacles behind the holographic 3D smart screen through the highly transparent video picture 2.

[0061] Among them, the front side of the holographic three-dimensional smart screen faces the user, and correspondingly, the back side of the holographic three-dimensional smart screen is opposite to the front side.

[0062] Here, since the blades of the holographic 3D smart screen rotate, they have a certain degree of transparency. And the lower the brightness of the video screen, the higher the transparency. Therefore, when the distance sensor detects an obstacle, by reducing the brightness of the video screen to the target brightness, the transparency of the video screen can be improved, so that the user can see the obstacle in front, and then avoid it in time to ensure the user's personal safety.

[0063] The above step of reducing the brightness of the video screen to the target brightness may specifically include the following steps:

[0064] Obtain characteristic parameters of the obstacle; determine a target safety level of the obstacle based on the characteristic parameters; and determine a target brightness corresponding to the target safety level based on a preset mapping relationship between the safety level and the brightness.

[0065] Specifically, when the target safety level of an obstacle is level 1, it means that the obstacle is very dangerous to the user, and the target brightness can be 10% of the original brightness of the video screen. When the target safety level of an obstacle is level 2, it means that the obstacle is generally dangerous to the user, and the target brightness can be 40% of the original brightness of the video screen. When the target safety level of an obstacle is level 3, it means that the obstacle does not pose a safety hazard to the user, and the target brightness can be 60% of the original brightness of the video screen.

[0066] Here, by determining the target safety level of the obstacle according to the characteristic parameters, and then according to the preset mapping relationship between the safety level and the brightness, the target brightness corresponding to the target safety level of the obstacle can be quickly and accurately determined.

[0067] The characteristic parameters mentioned above may include at least one of the following:

[0068] The distance between the obstacle and the electronic device, the speed of the obstacle and the volume of the obstacle.

[0069] Among them, the distance between the obstacle and the electronic device, the movement speed of the obstacle and the volume of the obstacle can all be determined based on the image collected by the camera.

[0070] For example, if the distance between the obstacle and the electronic device is far, that is, the distance between the obstacle and the electronic device is greater than a preset threshold (such as 10 meters), the target brightness can be reduced to 50% of the original brightness, that is, the transparency of the video screen increases slightly; if the distance between the obstacle and the electronic device is close, that is, the distance between the obstacle and the electronic device is less than or equal to the preset threshold, the target brightness can be reduced to 10% of the original brightness, that is, the transparency of the video screen increases significantly.

[0071] For example, if a car is driving very fast in front, that is, the speed of the obstacle is greater than the preset threshold, the target brightness can be reduced to 10% of the original brightness, that is, the transparency of the video screen is greatly improved; if a slow bicycle is driving in front of the electronic device, that is, the speed of the obstacle is less than or equal to the preset threshold, then the target brightness can be reduced to 60% of the original brightness, that is, the transparency of the video screen is increased less.

[0072] For example, if the volume of the obstacle is larger than a preset threshold, such as an electric pole, the target brightness can be reduced to 10% of the original brightness, that is, the transparency of the video screen is greatly improved; if the volume of the obstacle is less than or equal to the preset threshold, such as a puppy, the target brightness can be reduced to 60% of the original brightness, that is, the transparency of the video screen is increased less.

[0073] Different obstacles pose different levels of danger to users. Here, based on the preset mapping relationship between safety level and brightness, the target brightness corresponding to the target safety level is determined, which can more flexibly and effectively adjust the brightness of the video screen and better meet user needs.

[0074] In a possible embodiment, when an obstacle is detected, the following steps may also be included:

[0075] Output prompt information, which is used to remind the user that there are obstacles ahead.

[0076] Specifically, the prompt message "Please pay attention, there is an obstacle ahead" can be output through voice during a call, the prompt message can be displayed on the holographic three-dimensional smart screen, or the prompt message can be displayed on the current interface of the electronic device.

[0077] Therefore, by outputting prompt information for reminding the user that there is an obstacle ahead, the user can be reminded to pay attention to the obstacle ahead more intuitively and clearly, thereby ensuring the user's personal safety.

[0078] As an implementation of the present application, in order to improve the accuracy of obstacle recognition, before step 220, the following steps may also be included:

[0079] The volume of the object in the preset position area is obtained; when the volume of the object is greater than the preset volume threshold, the object is determined to be an obstacle.

[0080] In order to ensure that users can watch videos stably, the volume of objects in the preset position area can be obtained through the camera of the electronic device. When the volume of the object is greater than the preset volume threshold, the object is determined to be an obstacle and the brightness of the video screen is adjusted.

[0081] Among them, in the above-mentioned step of obtaining the volume of an object in a preset position area through a camera of an electronic device, the depth of field information can be determined by calculating two images taken by two cameras on the electronic device, and then the volume of the object can be measured.

[0082] The preset location area may be a sector-shaped area with the projection point of the electronic device on the ground as the center, the preset distance as the radius, and the preset arc.

[0083] That is, within the preset range, if the volume of an object is less than or equal to the preset volume threshold, such as a small stone with a volume less than 5 cubic centimeters, the object is not considered an obstacle, and there is no need to adjust the brightness of the video screen to ensure that users can watch the video stably.

[0084] In a possible embodiment, when a video call or video shooting ends, the display function of the holographic three-dimensional smart screen is turned off.

[0085] When the video call or video shooting ends, the holographic 3D smart screen is controlled to stop displaying the video image, the fan blades of the holographic 3D smart screen stop rotating, and the holographic 3D smart screen changes from an unfolded state to a folded state.

[0086] Here, if the user ends the video call or video shooting, the holographic three-dimensional smart screen is turned off so that the user can view the interface of the electronic device normally.

[0087] In summary, in an embodiment of the present invention, when a video call or video shooting is being conducted, the video screen of the video call or video shooting is displayed on the holographic three-dimensional smart screen, and when an obstacle is detected, the brightness of the video screen is reduced to the target brightness. Because the fan blades of the holographic three-dimensional smart screen rotate, there is a certain degree of transparency. And the lower the brightness of the video screen, the higher the transparency. Therefore, when an obstacle is detected in front of the user, by reducing the brightness of the video screen, the transparency of the video screen can be improved, so that the user can see the obstacle in front, and then can avoid it in time to ensure the user's personal safety.

[0088] It should be noted that the video screen display method provided in the embodiment of the present application can be executed by a video screen display device, or a control module in the video screen display device for executing the method for loading a video screen display. In the embodiment of the present application, the video screen display method provided in the embodiment of the present application is described by taking the video screen display device executing the method for loading a video screen display as an example.

[0089] In addition, based on the above-mentioned video screen display method, the embodiment of the present invention also provides a video screen display device, specifically combined with Figure 6 Provide detailed explanation.

Because the fan blades of the holographic three-dimensional smart screen rotate, there is a certain degree of transparency. And the lower the brightness of the video screen, the higher the transparency. Therefore, when an obstacle is detected in front of the user, the transparency of the video screen can be improved by reducing the brightness of the video screen, so that the user can see the obstacle in front, and then can avoid it in time to ensure the user's personal safety.
