Hereinafter, a display parameter adjustment method provided by an embodiment of the present invention will be described in detail with reference to the near-eye display device in fig. 1. It should be noted that the near-eye display device in fig. 1 is only used for explaining the display parameter adjustment method provided by the embodiment of the present invention, but does not limit the application scenario of the display parameter adjustment method provided by the embodiment of the present invention. In this embodiment, the near-eye display device may be AR glasses, VR glasses, AR helmets, or the like.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for adjusting display parameters according to an embodiment of the invention.
As shown in fig. 2, the display parameter adjustment method includes steps S101 to S102.
Step S101, when the near-eye display device is detected to be in a wearing state, determining a brightness variation value of the ambient light brightness detected by the near-eye display device within a preset duration.
In the embodiment of the disclosure, the near-eye display device may detect whether the near-eye display device is in a wearing state through a sensor, for example, when the near-eye display device is AR glasses, whether the near-eye display device is in a wearing state may be detected through a sensor arranged on a glasses frame and/or a glasses leg. The near-eye display device detects a change in ambient light brightness by the ambient light sensor at a timing or in real time when the near-eye display device is in a worn state. For example, an ambient light sensor may be provided on the frame or the temple of the AR glasses, and the ambient light sensor may detect a change in the ambient light level of the environment in which the AR glasses are placed. The near-to-eye display device may calculate a brightness variation value of the ambient light brightness within a preset period of time in detecting a variation of the ambient light brightness. It is understood that the brightness change value may be the ambient light brightness value detected at the first time minus the ambient light brightness value detected at the second time, or the ambient light brightness value detected at the first time minus the ambient light brightness value detected at the second time, and the time difference between the first time and the second time is equal to the preset time period. The brightness change value may be a positive value or a negative value.
In order to improve the cruising ability of the near-eye display device, in the embodiment of the disclosure, only when the near-eye display device is detected to be in a wearing state, an ambient light sensor in the near-eye display device is awakened, is in an operating state and detects ambient light brightness, and when the near-eye display device is in an unworn state, the ambient light sensor in the near-eye display device is in a dormant state.
In another embodiment, in the near-eye display device, a function key of the display parameter automatic adjustment function is set, and the function key may be a virtual key, for example, a function key of the display parameter automatic adjustment function may be set in a system setting option of the near-eye display device, a user may start the display parameter automatic adjustment function or close the display parameter automatic adjustment function by opening a system setting option and then triggering the function key of the display parameter automatic adjustment function in a screen of the near-eye display device, and the function key may also be a physical key, for example, when the near-eye display device is an AR glasses, a touch key may be set on a glasses leg, and the display parameter automatic adjustment function may be started or closed by the touch key. Only if the user turns on the automatic display parameter adjusting function of the near-eye display device, the near-eye display device can automatically adjust the display parameter according to the change of the ambient light brightness, so that if the near-eye display device is in a wearing state, the automatic display parameter adjusting function is not turned on, and the near-eye display device cannot automatically adjust the display parameter according to the change of the ambient light brightness.
Step S102, when the brightness change value is larger than a preset threshold value, the display parameters of the near-eye display device are adjusted according to the changed ambient light brightness value.
When the near-eye display device obtains a brightness change value of the ambient light brightness within a preset time period, the near-eye display device judges whether the brightness change value is larger than a preset threshold value. In the process of judging whether the brightness change value is greater than the preset threshold, the adopted brightness change value is the absolute value of the brightness change value obtained by calculation in the step S101, so that the relationship between the brightness change value of the ambient light brightness and the preset threshold can be accurately determined. The magnitude of the preset threshold may be set as needed, which is not particularly limited in the embodiments of the present disclosure. If the brightness change value is larger than the preset threshold value, the near-eye display equipment adjusts the display parameters according to the changed ambient light brightness value. It can be understood that the ambient light after the change=the ambient light before the change+the luminance change value, the luminance change value is a positive value when the ambient light is bright, and the luminance change value is a negative value when the ambient light is dark. The display parameters include at least one or more of display brightness, display resolution, display color. For example, when the near-eye display device is AR glasses, the display parameter is a parameter of an augmented reality display mode.
The embodiment adjusts the display parameters according to the change of the ambient light brightness only when the near-eye display device is in a wearing state, avoids adjusting the display parameters according to the change of the ambient light brightness when the near-eye display device is in a non-wearing state, reduces the adjustment times of the display parameters and improves the cruising ability of the near-eye display device, and in the process of adjusting the display parameters according to the change of the ambient light brightness, the display parameters can be automatically adjusted according to the change of the ambient light brightness only when the brightness change value of the ambient light brightness is larger than a preset threshold value, thereby avoiding the near-eye display device from frequently adjusting the display parameters according to the change of the ambient light brightness, reducing the electric quantity required by adjusting the display parameters and further improving the cruising ability of the near-eye display device.
In one embodiment, the step S102 includes:
and a step a of determining the type of the scene where the near-eye display equipment is currently located when the brightness change value is larger than a preset threshold value.
And when the brightness change value of the ambient light brightness is larger than the preset threshold value, the near-eye display equipment determines the type of the scene where the user is currently located. In the embodiment of the disclosure, the type of the scene currently located can be determined according to the display content of the near-eye display device and/or the application program running in the foreground. If the current display content of the near-eye display device is navigation related information, the near-eye display device can be determined to be in a navigation scene currently, and if the current application program of the near-eye display device running in the foreground is a video playing application, the near-eye display device can be determined to be in a video playing scene currently. An embodiment of determining the type of the scene in which the near-eye display device is currently located will be described later, and will not be repeated here.
And b, adjusting display parameters of the near-eye display equipment according to the type of the scene where the near-eye display equipment is currently located and the changed ambient light brightness value.
After determining the type of the current scene of the near-eye display device, the near-eye display device adjusts the display parameters of the near-eye display device according to the type of the current scene and the changed ambient light brightness value. It will be appreciated that when the type of scene in which the near-eye display device is located is different, the adjustment strategy for adjusting the display parameter may be different for the same ambient light level, such as different adjustment magnitudes for the same display parameter, the same ambient light level. In the disclosed embodiments, the near-eye display device has been assigned types in advance for various scenes. In an embodiment, the near-eye display device may determine, according to an application program currently running in the foreground, a type of a scene where the application program is currently located, that is, in the near-eye display device, a correspondence exists between the application program and the type of the scene.
The method comprises the steps of determining a display minimum parameter corresponding to a target type scene if the type of the scene where the near-eye display device is currently located and the changed environment light brightness value are the target type scene and the environment light brightness value before the change is larger than the environment light brightness value after the change, adjusting the display parameter of the near-eye display device according to the display minimum parameter if the display minimum parameter is larger than the target display parameter corresponding to the environment light brightness value after the change, and adjusting the display parameter of the near-eye display device according to the display minimum parameter if the display minimum parameter is smaller than or equal to the target display parameter.
If the type of the scene where the near-eye display device is currently located is determined to be a target type scene, determining whether the ambient light brightness value before the change is larger than the ambient light brightness value after the change. In the embodiment of the disclosure, the types of scenes where the near-eye display device is located are only two, one is a target type scene, and the other is a non-target type scene, wherein the target type scene is a scene with higher requirements on display parameters, such as a video playing scene, a video call scene and the like. It will be appreciated that when the ambient light level before the change is greater than the ambient light level after the change, this indicates that the ambient light is darkening, and when the ambient light level before the change is less than the ambient light level after the change, this indicates that the ambient light is brightening.
If the current scene type of the near-to-eye display equipment is a target type scene and the ambient light brightness value before the change is larger than the ambient light brightness value after the change, determining a display minimum parameter corresponding to the target type scene. Because the object type scene has a relatively high requirement on the real parameter, there is a minimum display parameter of the object type scene, and the minimum display parameter can be set by a user according to the requirement, and the size of the minimum display parameter is not limited.
And after the changed environment light brightness value is determined, determining a target display parameter corresponding to the changed environment light brightness value. In the near-eye display device, mapping relations between different ambient light brightness values and display parameters can be stored in advance, and based on the mapping relations, target display parameters corresponding to the changed ambient light brightness values can be determined. It is understood that when there are a plurality of display parameters, there is a corresponding mapping relationship between the different display parameters.
And after the target display parameters are determined, judging the size relation between the display minimum parameters and the target display parameters. When the size relation between the display minimum parameter and the target display parameter is judged, the display minimum parameter of the same kind is compared with the target display parameter of the same kind, for example, the display minimum parameter A is compared with the target display parameter A, and the display minimum parameter B is compared with the target display parameter B.
And if the display minimum parameter is larger than the target display parameter, adjusting the display parameter of the near-eye display device according to the display minimum parameter, namely adjusting the current display parameter of the near-eye display device to the display minimum parameter. If the minimum display parameter is smaller than or equal to the target display parameter, the near-eye display device adjusts the current display parameter according to the target display parameter, namely, adjusts the current display parameter into the target display parameter.
In another embodiment, if the type of the scene where the near-eye display device is currently located is a non-target type scene, the near-eye display device determines a target display parameter corresponding to the changed ambient light brightness value, and automatically adjusts the display parameter according to the target display parameter.
According to the embodiment, when the current scene of the near-eye display device is the target type scene, the current display parameter is regulated according to the size relation between the display minimum parameter of the target type scene and the target display parameter corresponding to the changed environment light brightness value, so that the display parameter regulation is avoided only according to the target display parameter, the display parameter regulation is carried out when the display minimum parameter is larger than the target display parameter, the display effect of the current scene of the near-eye display device is ensured, and the intelligence of the display parameter regulation is improved.
In one embodiment, the step S102 includes:
And c, determining the change amount of the pupil diameter of the user of the near-eye display device based on an eye tracking algorithm when the brightness change value is larger than a preset threshold value.
And d, if the change amount of the pupil diameter of the user is larger than the preset change amount, adjusting the display parameters of the near-to-eye display equipment according to the changed ambient light brightness value.
When the brightness change value of the ambient light is larger than the preset threshold value, the near-eye display device determines the change amount of the pupil diameter of the user of the near-eye display device based on an eye tracking algorithm. The pupil diameter of a human being automatically adjusts the pupil diameter according to ambient light level to control the amount of light entering the eye, and the pupil diameter is contracted in a bright environment and dilated in a dim environment. In this embodiment, in order to improve the accuracy of adjustment of the display parameter, the situation when the brightness change value of the ambient light is greater than the preset threshold is defined as a scene in which the ambient light brightness before the change is less than the ambient light brightness after the change, and at this time, the pupil diameter of the user will be reduced, that is, the pupil diameter before the change is greater than the pupil diameter after the change.
After determining the variation of the pupil diameter of the user, determining whether the variation of the pupil diameter of the user is larger than the preset variation, wherein the preset variation of different users can be the same or different, and the magnitude of the preset variation is not particularly limited in this embodiment. If the change amount of the pupil diameter of the user is larger than the preset change amount, the near-eye display device adjusts the display parameters according to the changed ambient light brightness value. If the change amount of the pupil diameter of the user is determined to be smaller than the preset change amount, the near-eye display device does not adjust the display parameters according to the changed ambient light brightness value and maintains the current display parameters, and if the change amount of the pupil diameter of the user is determined to be equal to the preset change amount, the near-eye display device can adjust the display parameters according to the changed ambient light brightness value and also can adjust the display parameters according to the changed ambient light brightness value.
It can be understood that when the ambient light becomes bright, if the change amount of the pupil diameter of the user is smaller than the preset change amount, it is indicated that the change of the ambient light brightness has little influence on the content displayed by the near-eye display device for viewing by the user, the display parameters can not be adjusted according to the ambient light brightness at this time, so as to avoid frequent adjustment of the display parameters, and if the change amount of the pupil diameter of the user is larger than the preset change amount, it is indicated that the change of the ambient light brightness has great influence on the content displayed by the near-eye display device for viewing by the user, at this time, the display parameters need to be adjusted according to the ambient light brightness, so that the accuracy of adjusting the display parameters of the near-eye display device is improved.
In another embodiment, when the brightness variation value is greater than a preset threshold, adjusting the display parameter of the near-eye display device according to the changed ambient light brightness value includes determining a current residual electric quantity of the near-eye display device if the ambient light brightness value before the change is less than the changed ambient light brightness value when the brightness variation value is greater than the preset threshold, and adjusting the display parameter of the near-eye display device according to the changed ambient light brightness value if the residual electric quantity is greater than or equal to the preset electric quantity.
When the brightness change value is determined to be larger than a preset threshold value, the near-to-eye display device judges whether the ambient light brightness value before the change is smaller than the ambient light brightness value after the change. If the brightness value of the environment light before the change is smaller than the brightness value of the environment light after the change, the near-to-eye display device determines the current residual electric quantity and judges whether the current residual electric quantity is larger than or equal to the preset electric quantity. The preset electric quantity can be set according to specific requirements, for example, 20% of the total electric quantity, or 10% of the total electric quantity.
If the residual electric quantity of the near-eye display device is larger than or equal to the preset electric quantity, the near-eye display device adjusts the display parameters according to the changed ambient light brightness value.
If the ambient light brightness value before the change is greater than the ambient light brightness value after the change, the ambient light brightness is darkened, and the current electric quantity of the near-eye display device is not considered at the moment, because when the ambient light brightness is darkened, the near-eye display device can adjust the display parameters thereof, such as reducing the display brightness, thereby reducing the power consumption of the near-eye display device, saving the electric quantity of the near-eye display device, and improving the cruising ability of the near-eye display device.
The display parameter adjusting method further comprises the step of maintaining the current display parameters of the near-eye display device if the residual electric quantity is smaller than the preset electric quantity.
If the residual electric quantity of the near-eye display device is smaller than the preset electric quantity, the near-eye display device maintains the current display parameters, and does not respond to the adjustment instruction for adjusting the display parameters, namely the display parameters are forbidden to be adjusted according to the changed ambient light brightness value.
According to the embodiment, when the brightness change value of the ambient light is larger than the preset threshold value and the brightness value of the ambient light before change is smaller than the brightness value of the ambient light after change, the display parameters of the near-eye display device are adjusted according to the brightness value of the ambient light after change only when the current residual electric quantity of the near-eye display device is larger than or equal to the preset electric quantity, and when the current residual electric quantity of the near-eye display device is smaller than the preset electric quantity, the display parameters are not adjusted according to the brightness value of the ambient light after change, so that the display parameters are adjusted under the condition that the electric quantity of the near-eye display device is enough, and the cruising ability of the near-eye display device is guaranteed in the process of intelligently adjusting the display parameters according to the change of the brightness value of the ambient light.
Referring to fig. 3, in an embodiment, when the brightness variation value is greater than a preset threshold value, adjusting the display parameter of the near-eye display device according to the changed ambient light brightness value includes:
Step S1021, when the brightness change value is larger than a preset threshold value, acquiring the current residual electric quantity of the near-eye display device;
Step S1022, if the residual electric quantity is smaller than the preset electric quantity, determining the fixation point position of the user wearing the near-eye display device;
When the brightness change value of the ambient light is larger than the preset threshold value, the near-eye display device obtains the current residual electric quantity of the ambient light, and determines whether the current residual electric quantity is smaller than the preset electric quantity. And if the current residual electric quantity is smaller than the preset electric quantity, the near-eye display equipment determines the fixation point position of the wearing user. The near-eye display device can determine the gaze point position of the wearing user through eye tracking technology.
In another embodiment, if the current remaining power of the near-eye display device is greater than or equal to the preset power, the near-eye display device may directly adjust its display parameters according to the changed ambient light brightness value.
Step S1023, if the gaze point is located in the display area of the near-eye display device, adjusting the display parameters of the near-eye display device according to the changed ambient light brightness value.
After determining the gaze point position of a wearing user wearing the near-eye display device, it is determined whether the gaze point position is located within the display area of the near-eye display device. If the gaze point position is determined to be located in the display area of the near-eye display device, the near-eye display device adjusts its display parameters according to the changed ambient light brightness value, and if the gaze point position is determined not to be located in the display area of the near-eye display device, the near-eye display device does not adjust its display parameters according to the changed ambient light brightness value.
In this embodiment, when the brightness change value is greater than the preset threshold and the current residual electric quantity of the near-eye display device is less than the preset electric quantity, the display parameter of the near-eye display device is adjusted according to the ambient light brightness only when the position of the user's gaze point is located in the display area of the near-eye display device, so that frequent adjustment of the display parameter according to the ambient light brightness is avoided, power consumption of the near-eye display device is increased, and cruising ability of the near-eye display device is improved.
In another embodiment, when the brightness change value of the ambient light is greater than a preset threshold value, it is determined whether the brightness of the ambient light after the change is greater than the brightness of the ambient light before the change. If the brightness of the changed environment is greater than the brightness of the environment before the change, when the residual electric quantity is smaller than the preset electric quantity and the fixation point is positioned in the display area of the near-eye display device, the display parameters of the near-eye display device can be adjusted according to the brightness value of the changed environment. If the changed ambient light brightness is smaller than the ambient light brightness before the change, the ambient light darkens, and at the moment, the near-eye display device can directly adjust the display parameters according to the changed ambient light brightness value without considering the electric quantity factor.
