Description

Display method and device

Technical field

The present application relates to the field of computer technology, and in particular, to a display method and apparatus.

Background technique

Currently, when the display interface is displayed, display parameters such as pixel density (Pixels Per Inch, PPI, also referred to as pixels per inch), sharpness, etc., determine the display effect of the displayed content, for example, in practical applications, The higher the resolution of the screen, the finer the displayed content. Conversely, the more coarse the displayed content; the higher the sharpness of the screen, the clearer the displayed content, and vice versa.

In the prior art, the display parameters of the display interface are usually preset by the device provider at the time of shipment, and then, when the screen is displayed, the display is performed based on the preset display parameters.

However, in the prior art, in order to achieve an optimal display effect of the screen, the default value of the display parameters preset by the device provider is usually high (for some display parameters, the default value is set to the highest state). In fact, since the recognition accuracy of the human eye is limited, in most scenes, the display parameters are not required to be too high, and the above-mentioned manner in the prior art always maintains a high display parameter, which undoubtedly increases the pair. The consumption of graphics processing resources in the terminal causes the graphics processor, memory and other devices in the terminal to always maintain a high workload, which wastes the processing resources of the terminal. Moreover, if the user wants to change the display parameters, it also needs to be in the corresponding setting options. Adjusting the display parameters one by one is cumbersome.

Summary of the invention

The embodiment of the present invention provides a display method for solving the problem that the display parameter adjustment process of the display interface is too cumbersome in the prior art.

The above at least one technical solution adopted by the embodiment of the present application can achieve the following beneficial effects:

During the display of the image on the display interface, the terminal will determine the user and the display interface in real time. The distance between the user and the display interface determines the value of the display parameter value of the display interface. Specifically, when the user is closer to the display interface, the user can identify the screen displayed on the display interface. For fine image details, when the user is far away from the display interface, the user's requirement for the fineness of the image will also decrease, so in the present application, the terminal will combine the preset distance according to the recognized distance. Corresponding to the display parameter, the display parameter suitable for the current distance is determined, and the image display is performed based on the determined display parameter.

Compared with the manner in which the display parameters that are fixed in the display interface are displayed in the prior art, the above method in the present application can dynamically adjust the display parameters according to the distance between the user and the display interface in real time, thereby saving internal processing of the terminal. The consumption of resources also avoids the tedious process of setting display parameters by the user.

detailed description

In order to make the purpose, technical solutions and advantages of the present application clearer, the following will be The technical solutions of the present application are clearly and completely described in the embodiments and the corresponding drawings. It is apparent that the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

As mentioned above, for the display interface, the device provider usually presets high display parameters at the factory to achieve the best display effect. Then, when the display interface displays the content, it will be based on The higher display parameters set in advance are displayed in a state of high definition, high pixel density, and the like. However, the clarity or pixel density that the human eye can recognize is limited, so when the display parameter exceeds a certain threshold, the human eye will have difficulty distinguishing the difference, which will cause waste of the processing resources of the terminal, and if the corresponding change is made The display parameters can only be set by the user, which is cumbersome.

Based on this, in the embodiment of the present application, a display method is provided, so that the terminal dynamically adjusts display parameters of the display interface according to the distance between the user and the display interface, and reduces processing resource consumption in the terminal while avoiding The cumbersome process of setting the display parameters one by one by the user manually.

In the embodiment of the present application, the terminal includes but is not limited to: a projection device, and a mobile terminal and a non-mobile terminal having a screen, where:

The projection device may specifically be a holographic projection device, and the projection image generated by the holographic projection device may include a three-dimensional projection image and a two-dimensional projection image.

The mobile terminal may include: a smart phone, a tablet computer, a smart watch, a virtual reality (VR) device, etc., and the non-mobile terminal may include a computer, a television, and the like. The VR device mentioned here further includes: at least one of an external VR glasses (having a screen by itself), a mobile VR glasses (a VR glasses frame is used in conjunction with a mobile phone, and a mobile phone display screen is used as a screen when in use).

In addition, for the foregoing terminal, in an embodiment of the present application, the terminal itself has a ranging function, and the ranging function is implemented by a distance sensor on the terminal, wherein the distance sensor may be: an infrared ranging sensor. , ultrasonic ranging sensors, optical ranging sensors, and so on.

In another embodiment of the present application, the device used in combination with the terminal has a ranging function, and the device transmits the measured distance data to the terminal in real time. Such as: for mobile VR glasses In other words, the object distance adjustment wheel on the frame of the VR glasses transmits the measured object distance (in the VR scene, the distance between the object and the screen to the human eye) to the mobile phone in real time.

Of course, the above does not constitute a limitation on the present application.

In an embodiment of the present application, the interaction scenario between the user and the terminal may be as shown in FIG. 1a. The image display process provided in the embodiment of the present application is as shown in FIG. 1b, and the process specifically includes the following. step:

S101: Determine a distance between the display interface and the user.

In this embodiment, for the display interface, in one scenario, if the terminal itself has a screen, the display interface is a terminal screen; and in another scenario, the terminal has a projection function but does not have The screen for displaying the content displays the interface on which the image projected by the terminal is based, and the interface may be a plane such as a wall or a screen, or a non-physical interface such as air, airflow, or water flow.

The distance refers to the line of sight distance from the user's eyes to the terminal screen. It is to be understood that the distance between the user and the display interface may be determined by the user's determination of the distance between the user and the display interface. Determine the value of the subsequent display parameters.

It should be noted that determining the line of sight distance between the terminal screen and the user may be implemented by a corresponding ranging sensor in combination with a corresponding ranging algorithm (eg, a human eye position tracking algorithm, a face tracking algorithm, etc.), of course, the ranging sensor The principle of ranging is not a protective content of the present application, so it will not be discussed too much here.

S102: Determine, according to a correspondence between the preset distance and the display parameter, a display parameter corresponding to the distance of the display interface to the user.

Considering that in the actual application scenario, the ability of the human eye to recognize the details of the image is related to the distance between the eye and the picture. Specifically, the closer the human eye is to the picture, the clearer the image details that can be recognized, and vice versa. The coarser the details of the identifiable image, that is, if the distance between the user's eyes and the terminal screen is closer, the display parameters of the terminal screen should be higher in order to maintain a higher display effect, and if the user's eyes are If the distance from the terminal screen is far, the display parameters of the terminal screen should be reduced accordingly. In order to reduce the processing resource consumption inside the terminal.

In other words, the value of the display parameter is high or low and is inversely related to the distance between the user and the screen. Therefore, in the embodiment of the present application, the correspondence between the preset distance and the display parameter is set according to the negative correlation relationship. In a typical application scenario, the correspondence includes a plurality of medium distance intervals, and display parameters corresponding to each distance interval, for example, in a distance range of 20CM-25CM, the PPI is 320; at 30CM-50CM Within the distance, the PPI is 280. In the scenario where the distance accuracy is high, the correspondence may be stepped, that is, as the distance changes, the value of the display parameter also changes.

In the actual operation, the corresponding relationship may be saved in the terminal by means of a configuration file, so the terminal can directly read the corresponding relationship in the configuration file to determine the specific value of the display parameter at the current distance. Certainly, the corresponding relationship may also be stored in a corresponding server, and the terminal may send an acquisition request to the server to obtain the corresponding relationship, and determine a display parameter at a current distance. The specific method is specifically determined according to the needs of the actual application, and does not constitute a limitation on the present application.

S103: Display according to the determined display parameter.

The determined display parameter is matched with the current distance between the terminal screen and the user, that is, the terminal screen is displayed based on the current display parameter, and the display effect can match the user's display content details at the current distance. Recognition ability.

Through the above steps, in the process of displaying the image on the display interface, the terminal determines the distance between the user and the display interface in real time, and the distance between the user and the display interface determines the level of the display parameter value of the display interface, specifically In the case that the user is closer to the display interface, the user can recognize finer image details for the screen displayed on the display interface, and the user has a requirement for the fineness of the screen when the user is far away from the display interface. In the present application, the terminal determines the display parameter suitable for the current distance according to the identified distance and the correspondence between the preset distance and the display parameter, and based on the determined Display parameters for image display.

Compared with the manner in which the display parameters that are fixed in the display interface are displayed in the prior art, the present application The above method can dynamically adjust the display parameters according to the distance between the user and the display interface in real time, which can save the consumption of the internal processing resources of the terminal and avoid the cumbersome process of setting the display parameters by the user.

It should be noted that, in the foregoing, in one mode, the execution body of the display method may be a terminal. Specifically, the terminal itself has a ranging sensor, and the operating system obtains a display interface by using a ranging sensor. The distance from the user, after calculating the value of the display parameter corresponding to the current distance according to the corresponding relationship between the preset distance and the display parameter, calling the interface displaying the adjustment function in the operating system, and changing the corresponding display parameter.

In another mode, for the determination process of the distance, the execution body may be an external sensor. At this time, the terminal sends an instruction to the external sensor, and the distance between the display interface and the user is obtained by the external sensor, and the subsequent terminal may be Based on the obtained distance, the display parameters are determined and displayed according to the display parameters.

Of course, the third party application (Application, APP) running in the terminal may also be used as an execution subject. In this case, the third party APP obtains the authority in the terminal operating system to acquire the distance and adjust the display parameters of the terminal. . This does not constitute a limitation on the present application.

In the actual application scenario, in determining the distance between the terminal screen and the user, the terminal often needs to monitor the user, that is, the display parameter of the display interface needs to be dynamic only before the user is in the display interface. In the embodiment of the present application, determining the distance between the display interface and the user includes: monitoring a user who is within the visible range of the display interface, and measuring when the user is in the visible range The distance between the display interface and the user.

In the above process, the visual range of the display interface indicates that the user can normally view the range of the displayed content, and the visible range is usually determined by the viewing angle and the visible distance. For example, for the terminal shown in FIG. 1a, the visible range is as shown in FIG. 2.

The monitoring of the user in the visible range of the terminal can be implemented by the monitoring function in the terminal system. Specifically, the distance between the display interface and the user is determined, which specifically includes:

Displaying the operating system of the terminal on which the interface is based, calling the monitoring function, and monitoring is in the display boundary The user within the visible range, and when monitoring that the user is within the visible range, measures the line of sight distance between the display interface and the user. In practical applications, the infrared sensor, camera and other devices on the terminal can be used as the ranging sensor. That is to say, the monitoring function in the terminal operating system can obtain the display interface from the ranging sensor on the terminal through the corresponding data interface. The distance data between users does not constitute a limitation on the present application.

Once the terminal detects that the user appears within its visible range, the distance between the display interface and the user is further determined, and the display parameters applicable to the current distance can be further determined. As a method in the actual application, the correspondence between the preset distance and the display parameter includes: a correspondence between the pre-divided distance interval and the display parameter, then, in this manner, according to the preset distance and display Determining, by the preset relationship, the display parameter that matches the distance between the display interface and the user, and the method includes: determining a preset distance interval in which the distance between the display interface and the user falls, according to a preset The display parameter corresponding to the preset distance interval is determined by the correspondence between the distance and the display parameter, and the determined display parameter is used as the display parameter matched by the display interface to the distance of the user.

As shown in FIG. 3a, the correspondence between different distance intervals and display parameters is shown. As can be seen from FIG. 3a, each of the four distance ranges 0-20, 21-40, 41-60, and 61-80 The display parameter corresponding to a distance interval (only the display parameter is PPI in FIG. 3a) has only one value, and it can be considered that the value of the corresponding display parameter in each distance interval is the distance interval. The optimized value within the range, that is, the display parameter value is within the distance interval, and the optimal display effect can be achieved.

In practical applications, the distance interval can be divided according to the needs of the actual application. For example, in a scene with high display accuracy requirements (such as VR scene), the distance interval can be precisely divided to make the length of each distance interval. Very short (eg 1CM or 0.1CM), and if the scene with lower display accuracy is required, the length of the distance interval can be set longer (as in the example in FIG. 3a above), which does not constitute a limitation on the present application. .

Of course, in addition to the distance interval can be divided according to the actual application, the display parameters corresponding to different distance intervals can also be set according to the needs of the actual application, as shown in FIG. 3b, in the display In a scenario where the accuracy is high, the degree of change of the display parameters is different as the distance between the user and the terminal screen changes.

In practical applications, the use of VR devices is becoming more and more extensive. Among them, a VR device is called mobile VR glasses, and the mobile VR glasses support the VR-enabled mobile phone in the VR glasses frame, so that the composition can be used. VR glasses, for this application scenario, it can be understood that the display of the mobile phone screen has a high requirement on the display parameters after being placed in the VR glasses frame. In the embodiment of the present application, a display method is provided, which is applicable to the VR scene, as shown in FIG. 4 . The method specifically includes the following steps:

S401: Monitor the display mode of the terminal itself.

In this embodiment, the terminal should be understood to be applicable to both normal usage scenarios and various types of terminals in the VR scenario, such as a mobile phone with a VR function, a tablet computer, and VR glasses.

In the actual application, the terminal does not have the same requirements for the display parameters in the normal use scenario and in the VR scenario. Therefore, in this scenario, the user can use the terminal in the VR scenario, and the VR function of the terminal is started. At this time, the display model of the terminal will change, so the display mode of the terminal will be monitored so that the display parameters of the terminal can be adjusted in the subsequent process.

It should be noted that, in this embodiment, the monitoring process of the display mode of the terminal itself may be implemented by the display mode monitoring function in the terminal operating system, or may be displayed by a corresponding application (it should be understood that in this case, the application is obtained) The authority to monitor and change the display mode in the terminal is not specifically limited here.

S402: Determine the object distance between the terminal screen and the user's eyes when the display mode is monitored as the virtual reality VR display mode.

When the terminal enters the VR mode, it usually indicates that the terminal has been matched with the external VR wearable device, for example, the mobile phone is placed in an external VR glasses frame.

The specific measurement process is not described here.

S403: Determine, according to a preset correspondence between the object distance and the display parameter, a display parameter corresponding to the object distance of the terminal screen and the user.

In this embodiment, after the user uses the external VR wearing device with the terminal, since the distance between the user's eyes and the terminal screen is relatively close, the terminal screen has higher requirements on the display parameters, so the terminal screen Changes in the object distance between the user and the display parameters will also change accordingly.

S404: Perform VR display according to the determined display parameter.

For the above scenario, it should be noted that the user can actively control the terminal to perform the VR display mode, or when the user places the terminal into the external VR wearable device, the terminal will switch to the VR display mode by itself, so when monitoring Before the display mode is the VR display mode, before determining the object distance between the terminal screen and the user's eyes, the method further includes: the terminal receiving the VR display mode command sent by the user, or the terminal receiving the wearable device with the external VR Match notifications.

In a possible case, since the display parameters of the terminal screen are required in the VR display mode, when the terminal switches to the VR display mode, the display parameters of the terminal screen are suitable for the VR display, so in this implementation In an example, before determining the object distance between the terminal screen and the user's eyes, the method further includes: displaying according to the basic display parameter preset for the VR display mode.

The basic display parameters described herein are display parameters suitable for the VR display of the terminal screen. Generally, the value of the basic display parameters will not be lower than the value of the display parameters in the normal display mode. Of course, there is no specific limit here.

Further, the ranging module 501 monitors a user who is within the visible range of the display interface, and measures the distance between the display interface and the user when the user is detected to be within the visible range.

In one mode, the corresponding relationship includes: a correspondence between the pre-divided distance interval and the display parameter, then the determining module 502 determines a preset distance interval in which the distance between the display interface and the user falls. Determining, according to a correspondence between the preset distance and the display parameter, a display parameter corresponding to the preset distance interval, and using the determined display parameter as a display parameter that matches the distance of the display interface to the user . Wherein, the pre-divided distance interval is negatively correlated with the value of the display parameter.

In another mode, the correspondence relationship includes: a correspondence between the unit distance and the display parameter, and then the determining module 502 determines the distance value of the display interface to the user according to the correspondence between the unit distance and the display parameter. The corresponding display parameter value, wherein the distance value is inversely proportional to the display parameter value.

Based on the above, the display parameter includes at least one of resolution, pixel density PPI, sharpness, refresh rate, and frame rate.
