The video image display method provided by the embodiment of the invention can be applied to the following application scenarios, which are explained below.
As shown in fig. 1, when a user uses an electronic device to perform a video call, a front camera of the electronic device is directed to the user to shoot, and accordingly, a video picture of the other party is displayed on an interface of the electronic device of the user, so that the video call between both parties is realized. Because the display screen of the electronic equipment is opaque, and when a user carries out a video call, the sight of the user is often focused on the display screen of the electronic equipment, and objects in the real world on the back of the electronic equipment cannot be seen. Therefore, when the user walks, the user can easily bump into the sunken barrier on the road during the video call, and personal safety is affected.
In addition, when a user uses the electronic device to shoot a video (for example, the user uses the front camera to shoot a Vlog towards the user), the sight of the user is often focused on a video picture of a display screen of the electronic device, so that objects in the surrounding area are easily ignored, and certain potential safety hazards are brought.
The situation that the user uses the electronic equipment to shoot the video also comprises the situation that the user uses the electronic equipment to carry out live broadcasting, when the user carries out live broadcasting, the sight of the user is always focused on a live broadcasting interface of the electronic equipment, and the attention of the user is always focused on user comments on the live broadcasting interface and a live video picture of the user. Objects in the surrounding area cannot be seen, so that potential safety hazards are brought, and personal safety is influenced.

The method provided by the embodiment of the invention can be applied to the application scenes, and can also be applied to scenes that dangerous objects in the surrounding area are ignored and potential safety hazards are brought when a user uses the electronic equipment.
According to the method provided by the embodiment of the invention, under the condition of video call or video shooting, the video picture of the video call or video shooting is displayed on the holographic three-dimensional intelligent dazzling screen, and under the condition of detecting the obstacle, the brightness of the video picture is reduced to the target brightness. As the fan blades of the holographic three-dimensional intelligent dazzling screen rotate, the screen has certain transparency. And the lower the brightness of the video picture is, the higher the transparency is, so when an obstacle in front of the user is detected, the transparency of the video picture can be improved by reducing the brightness of the video picture, so that the user can see the obstacle in front, and can avoid the obstacle in time, and the personal safety of the user is guaranteed.
In the following, the holographic three-dimensional intelligent glare screen and the distance sensor presented in the present application are explained and illustrated.
Holographic three-dimensional intelligent glare screens, also known as Light Emitting Diode (LED) fans, and "rotating LED Light bars. After the LED fan (being the screen is dazzled to holographic three-dimensional intelligence) was opened, the flabellum of LED fan began to rotate, can demonstrate a three-dimensional image when rotatory, and is cool to dazzle lifelike. Meanwhile, according to the size and the color of a video picture, the fan blades of the LED fan can be well hidden in the rotating process.
The holographic three-dimensional intelligent dazzling screen not only utilizes hardware equipment of a rotary LED, but also utilizes the phenomenon of persistence of vision of human eyes. Aiming at the hardware configuration of the rotating LED, the change frequency of the LED lamp is simply calculated according to the rotating speed of the fan blades, and different Meipu light LED lamps are lighted at different moments to present different patterns.
The persistence phenomenon refers to that when human eyes observe a scene, a light signal is transmitted into brain nerves, a short time is needed, after the action of light is finished, a visual image does not disappear immediately, the human eyes can still keep the image for about 0.1 to 0.4 seconds, the residual vision is called 'afterimage', and the phenomenon of vision is called 'persistence'.
Therefore, the holographic three-dimensional intelligent dazzling screen can be used for displaying clear and smooth video pictures.
Based on the application scenario, the following describes in detail a video image display method provided by an embodiment of the present invention.
Fig. 2 is a flowchart of a video frame display method according to an embodiment of the present invention.
As shown in fig. 2, the display method may include steps 210-220, and the method is applied to a video picture display device, and specifically as follows:
and 210, under the condition that the electronic equipment is in a target scene, displaying a video picture corresponding to the target scene on the holographic three-dimensional intelligent dazzling screen, wherein the target scene comprises a video call scene or a video shooting scene.
And step 220, reducing the display brightness of the video picture to the target brightness under the condition that the obstacle is detected.
According to the video picture display method provided by the embodiment of the invention, the video picture of the video call or the video shooting is displayed on the holographic three-dimensional intelligent dazzling screen under the condition of carrying out the video call or the video shooting, and the brightness of the video picture is reduced to the target brightness under the condition of detecting the obstacle. As the fan blades of the holographic three-dimensional intelligent dazzling screen rotate, the screen has certain transparency. And the lower the brightness of the video picture is, the higher the transparency is, so when an obstacle in front of the user is detected, the transparency of the video picture can be improved by reducing the brightness of the video picture, so that the user can see the obstacle in front, and can avoid the obstacle in time, and the personal safety of the user is guaranteed.
The contents of steps 210-220 are described below:
first, step 210 is involved.
And under the condition of video call or video shooting, displaying a video picture of the video call or video shooting on the holographic three-dimensional intelligent dazzling screen.
As shown in fig. 3, a foldable holographic three-dimensional intelligent dazzling screen is additionally arranged on the back surface of the electronic device, and is in a folded state in daily life. A distance sensor can be installed at the circle center of the back of the foldable holographic three-dimensional intelligent dazzling screen.
The holographic three-dimensional intelligent dazzling screen and the distance sensor are in a power-off state under the condition of non-video call or video shooting. As shown in fig. 4, when a video call or a video shot is performed, the foldable holographic three-dimensional intelligent dazzling screen on the back of the electronic device is changed from a folded state to an unfolded state, the fan blades of the holographic three-dimensional intelligent dazzling screen start to rotate, and a video picture of the video call or the video shot is displayed on the holographic three-dimensional intelligent dazzling screen. And correspondingly starting the distance sensor to start obstacle ranging.
In a possible embodiment, before the step related to displaying the video picture corresponding to the target scene on the holographic three-dimensional intelligent glare screen, the following steps may be further included:
receiving a first input of a user; and responding to the first input, and starting the holographic three-dimensional intelligent dazzling screen.
Illustratively, a first input of a user to the holographic three-dimensional intelligent dazzling screen is received, and the holographic three-dimensional intelligent dazzling screen is started in response to the first input, namely the holographic three-dimensional intelligent dazzling screen is changed from a folded state to an unfolded state for displaying video pictures on the holographic three-dimensional intelligent dazzling screen.
The first input referred to above may be input by a user to a holographic three-dimensional intelligent touch screen switch button, or touch input on an interface of the electronic device, or gesture input to the electronic device.
Therefore, the holographic three-dimensional intelligent dazzling screen is started again by responding to the first input of the user. Can make holographic three-dimensional intelligence dazzle the screen and open when the user needs, laminate user's needs more, promote user experience.
Then, step 220 is involved.
The obstacle can be detected by a distance sensor, or can be detected by a camera by double-shooting distance measurement. The following description is made in order:
first, a distance sensor, also called a displacement sensor, is a type of sensor for sensing a distance between the sensor and an object to perform a predetermined function. The distance sensor can be classified into an optical distance sensor, an infrared distance sensor, an ultrasonic distance sensor and the like according to different working principles.
The distance sensors used in electronic devices are mostly infrared distance sensors, which have an infrared transmitting tube and an infrared receiving tube. The distance between the object and the infrared detector can be calculated by emitting infrared rays, reflecting the infrared rays by a close object, and receiving the intensity of the infrared rays by the infrared detector.
The working principle of other types of distance sensors is also similar, and the distance is judged by the emission and the reception of certain substances, wherein the emitted substances can be ultrasonic waves, light pulses and the like.
And secondly, double-shooting distance measurement, namely calculating two images shot by two cameras on the electronic equipment to determine depth of field information, and further measuring and calculating the physical distance between the object and the electronic equipment and the physical size of the object.
When the obstacle is detected, the brightness of the video image is reduced to the target brightness, the video image with the target brightness can enable a user to see the video image displayed by the holographic three-dimensional intelligent dazzling screen and also see the obstacle on the back of the electronic equipment, and then the obstacle on the back of the electronic equipment is avoided.
As shown in fig. 5, when no obstacle is detected, the holographic three-dimensional intelligent glare screen displays a video picture 1, and when the distance sensor detects an obstacle (a seat or an electric vehicle), the brightness of the video picture 1 is reduced to a target brightness, so that a video picture 2 is obtained. The transparency of the video picture 2 displayed by the holographic three-dimensional intelligent dazzling screen is obviously improved, and a user can see the real world barrier on the back of the holographic three-dimensional intelligent dazzling screen through the high-transparency video picture 2.
The front face of the holographic three-dimensional intelligent dazzling screen faces a user, and correspondingly, the back face of the holographic three-dimensional intelligent dazzling screen is opposite to the front face.
Here, the blades of the holographic three-dimensional intelligent dazzling screen rotate and have certain transparency. And the lower the brightness of the video picture is, the higher the transparency is, so that under the condition that the distance sensor detects the obstacle, the transparency of the video picture can be improved by reducing the brightness of the video picture to the target brightness, so that a user can see the obstacle in front, and can avoid in time, and the personal safety of the user is guaranteed.
The step of reducing the brightness of the video frame to the target brightness may specifically include the following steps:
acquiring characteristic parameters of an obstacle; determining a target safety level of the barrier according to the characteristic parameters; and determining the target brightness corresponding to the target safety level according to the preset mapping relation between the safety level and the brightness.
Specifically, when the target safety level of the obstacle is one level, it indicates that the obstacle is dangerous for the user, and the target brightness may be 10% of the original brightness of the video picture. When the target safety level of the obstacle is two levels, the obstacle is generally dangerous for the user, and the target brightness can be 40% of the original brightness of the video picture. When the target safety level of the barrier is three levels, the barrier does not have potential safety hazard for users, and the target brightness can be 60% of the original brightness of the video picture.
Here, the target safety level of the obstacle is determined according to the characteristic parameter, and then the target brightness corresponding to the target safety level of the obstacle can be determined quickly and accurately according to the preset mapping relationship between the safety level and the brightness.
Wherein, the mentioned characteristic parameters may include at least one of the following:
a distance between the obstacle and the electronic device, a speed of movement of the obstacle, and a volume of the obstacle.
The distance between the obstacle and the electronic equipment, the movement speed of the obstacle and the volume of the obstacle can be determined according to the image acquired by the camera.
For example, if the distance between the obstacle and the electronic device is long, that is, the distance between the obstacle and the electronic device is greater than a preset threshold (for example, 10 meters), the target brightness may be reduced to 50% of the original brightness, that is, the transparency of the video frame is increased by a small amount; if the distance between the obstacle and the electronic device is short, 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 image is greatly increased.
For example, if a vehicle with a fast speed is driven in front, that is, the moving speed of an obstacle is greater than a preset threshold, the target brightness may be reduced to 10% of the original brightness, that is, the transparency of the video image is greatly increased; if a slow bicycle is driven in front of the electronic device, that is, the movement speed of the obstacle is less than or equal to the preset threshold, the target brightness can be reduced to 60% of the original brightness, that is, the transparency of the video image is increased by a small amount.
For example, if the volume of the obstacle is greater than a preset threshold, for example, if the obstacle is a telegraph pole, the target brightness may be reduced to 10% of the original brightness, that is, the transparency of the video frame is greatly increased; if the volume of the obstacle is less than or equal to the preset threshold value, for example, the obstacle is a puppy, the target brightness can be reduced to 60% of the original brightness, that is, the transparency of the video frame is increased by a small amount.
Different barriers are different in danger degree for users, and the target brightness corresponding to the target safety level is determined according to the preset mapping relation between the safety level and the brightness, so that the brightness of a video picture can be adjusted more flexibly and effectively, and the requirements of the users are met.
In a possible embodiment, in case an obstacle is detected, the following steps may be further included:
and outputting prompt information for prompting that the obstacle exists in front of the user.
Specifically, a prompt message "please pay attention to, there is an obstacle in front of" may be output by a call voice, the prompt message may also be displayed on the holographic three-dimensional intelligent dazzling screen, and the prompt message may also be displayed on the current interface of the electronic device.
Therefore, the prompt information used for prompting that the obstacle exists in front of the user is output, so that the user can be more intuitively and clearly reminded of paying attention to the obstacle in front, and personal safety of the user is further guaranteed.
As an implementation manner of the present application, in order to improve the accuracy of obstacle identification, before step 220, the following steps may be further included:
acquiring the volume of an object in a preset position area; and determining that the object is an obstacle under the condition that the volume of the object is larger than a preset volume threshold value.
In order to ensure that a user can watch videos stably, the volume of an object in a preset position area can be obtained through a camera of the electronic equipment, and when the volume of the object is larger than a preset volume threshold value, the object is determined to be an obstacle, and the brightness of a video picture is adjusted.
In the above step of obtaining the volume of the object in the preset position area through the camera of the electronic device, the depth of field information may be determined by calculating two images obtained by two cameras on the electronic device, and then the volume of the object is measured.
The preset position area may be a sector area with a projection point of the electronic device on the ground as a sector center, a preset distance as a radius, and a preset radian.
That is, in the preset range, if the volume of the object is less than or equal to the preset volume threshold, for example, the volume of the object is less than 5 cubic centimeters of small stones, the object is not considered as an obstacle, and the brightness of the video picture does not need to be adjusted, so that the user can stably watch the video.
In one possible embodiment, the display function of the holographic three-dimensional intelligent dazzling screen is turned off when the video call or video shooting is finished.
Under the condition that video call or video shooting is finished, the holographic three-dimensional intelligent dazzling screen is controlled to stop displaying video pictures, fan blades of the holographic three-dimensional intelligent dazzling screen stop rotating, and the holographic three-dimensional intelligent dazzling screen is changed into a folded state from an unfolded state.
Here, if the user ends the video call or the video photographing, the holographic three-dimensional intelligent glare screen is closed, so that the user can normally view the interface of the electronic device.
In summary, in the embodiment of the present invention, when a video call or a video shot is performed, a video picture of the video call or the video shot is displayed on the holographic three-dimensional intelligent glare screen, and when an obstacle is detected, the brightness of the video picture is reduced to the target brightness. As the fan blades of the holographic three-dimensional intelligent dazzling screen rotate, the screen has certain transparency. And the lower the brightness of the video picture is, the higher the transparency is, so when an obstacle in front of the user is detected, the transparency of the video picture can be improved by reducing the brightness of the video picture, so that the user can see the obstacle in front, and can avoid the obstacle in time, and the personal safety of the user is guaranteed.

The embodiment of the present application describes a video image display method provided by the embodiment of the present application, by taking an example in which a video image display device executes a loaded video image display method.
