Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without undue burden, are within the scope of the present application.
Referring to fig. 1, a schematic flow chart of a display control method provided in an embodiment of the present application is shown, and the method in the embodiment may be applied to an electronic device. The method of the embodiment can comprise the following steps:
S101, determining a first display image watched by an observer on a target device.
Wherein the electronic device is capable of presenting a display image through the target apparatus.
In this application, the target device can be penetrated by visible light, so that the target device is relatively easy to be affected by external environmental factors such as light, and the situation that the effect of watching the display image by a user is easily affected can easily occur.
For example, the target device may be a light transmissive display device, such as a transparent display device, coupled to an electronic apparatus, etc., to which the electronic apparatus may output a display image to present the display image on the target device.
As another example, the target device may be a device such as glass that is capable of being penetrated by visible light, and the electronic apparatus may utilize the principle of optical reflection to project a display image onto the target device so that the display image can be presented to the user.
The first display image is a partial image which is watched by the observer among display images displayed on the target device. Based on this, the observer can observe the first display image and the second display image from the target device. The second display image is different from the first display image, for example, the second display image is the whole or part of the display image except the first display image on the target device.
In the present application, the first display image at which the observer's gaze is determined may be determined by capturing the line of sight of the observer. For example, an eye image of an observer may be obtained, a gaze area of the eye image of the observer on the display device may be determined, a first display image of the display device within the gaze area may be determined,
of course, other possibilities of determining the first display image at which the observer looks are possible, which the present application does not limit.
S102, adjusting display parameters to enable the first display image and the second display image to show different display effects.
The display parameters refer to parameters of the electronic device for outputting display images. For example, the display parameter may be a parameter for controlling at least one of display brightness, display color, and image size of the display image.
In the application, the display effect of at least one of the first display image and the second display image can be changed by adjusting the display parameter, so that the first display image and the second display image show different display effects.
In one possible implementation manner, the application may adjust a display parameter corresponding to the first display image or the second display image, so that the first display image and the second display image exhibit different display effects. For example, at least one of display brightness, display color, and image size of the first display image or the second display image may be adjusted.
It can be appreciated that controlling the first display image to present a different display effect than the second display image is beneficial to distinguishing or highlighting the first display image, so that the user can more conveniently and intuitively pay attention to the content of the first display image.
In one alternative, the viewer's line of sight is detected to be away from the first display image, and the adjusted display parameters are restored to the pre-adjustment display parameters so that the first display image and the second display image exhibit the same display effect.
For example, after the display color of the first display image or the second display image is adjusted, the display color of the first display image or the second display image may be restored to the color before adjustment.
From the above, in the present application, the target device can be penetrated by visible light, so that the display effect of the display image output by the target device is relatively more susceptible to the external environment. On the basis, after confirming the first display image watched by the observer of the target device, the display parameters are adjusted, so that the first display image and the second display image outside the first display image in the target device show different display effects, the first display image can be highlighted, a user can more intuitively see the content of the first display image, and further, information in the first display image can be more effectively captured.
It will be appreciated that the target device may have different possibilities under different application scenarios, and the display content that needs to be presented in the target device may also be different. Several possible scenarios to which the scheme of the present application can be applied are described below as examples.
In one possible case, in the vehicle information display scene, the target device may be a projection imaging device in a vehicle cabin for presenting the vehicle information projected by the projection device.
In this scenario, the electronic device may be a control device in the vehicle for controlling the projecting device to project vehicle information outwards, for example, the electronic device may be a head-up display device in the vehicle or a whole vehicle control device including the head-up display device.
The projection imaging device may be a front windshield of a vehicle or the like, or other transparent device independent of the electronic device.
The projection imaging apparatus may also be a transparent display or the like, without limitation.
Accordingly, the first display image and the second display image belong to an image of the vehicle information presented in the projection imaging apparatus.
In such a scene, the vehicle information presented by the projection imaging apparatus may be information on the vehicle itself or information related to the running of the vehicle.
For example, the vehicle information may include information related to the vehicle itself, such as the speed, tire pressure, and oil pressure of the vehicle, and may also include information related to the driving of the vehicle, such as navigation information, weather of the environment in which the vehicle is located, and temperature. Of course, the vehicle information may also include other vehicle-related information, without limitation.
In yet another possible scenario, in a virtual image display scenario such as virtual reality or augmented reality, the target device may be a transparent imaging device for presenting a virtual image, such as a transparent imaging device on virtual reality glasses or other smart wearable devices, without limitation.
In such a scene, the first display image and the second display image belong to a virtual image presented in the transparent imaging device.
Of course, other application scenarios are also possible in the solution of the present application, and will not be described herein.
In the above embodiments of the present application, in order to reduce adjustment of the display parameters due to erroneous judgment, the present application needs to adjust the display parameters only when the observer looks at the first display image to satisfy the setting condition. Wherein the setting conditions may be a plurality of possibilities.
For example, in a first possible case, the display parameter is adjusted upon determining that the cumulative length of time the first display image is gazed by the observer for the set time reaches the first set time.
The setting time may be set as needed, for example, the setting time may be 20 seconds.
The first set duration is less than the duration of the set time.
If the set duration is 20 seconds, the first set duration may be 12 seconds, and then the accumulated duration of the observer looking at the first display image in 20 seconds reaches 12 seconds, the display parameter may be triggered and adjusted so that the display effects of the first display image and the second display image are different.
It will be appreciated that if the viewer's line of sight is directed at the first display image, then the viewer's line of sight may soon be diverted from the first display image to other image areas on the target device or be removed from the target device if the viewer is not directed at the content of the first display image.
If the observer wishes to know the information of the first display image, the observer must stay on the first display image for a period of time in order to see the information of the first display image, and then the period of time in which the first display image is accumulated to be gazed by the observer must be relatively long.
In addition, if the user's line of sight stays on the first display image for a short time, the user may not be able to see the content of the first display image clearly, and then the user must need to view the first display image again in a short time, which also necessarily makes the cumulative time period during which the user looks at the first display image relatively longer in the set time.
From the above analysis, it is known that, when the cumulative time length of the observer watching the first display image reaches the first set time length within the set time, the display parameter is adjusted, so that the situation that the observer carelessly scans the first display image and mistakenly triggers the adjustment of the display parameter can be effectively reduced, and the accuracy of display control can be improved.
For example, for ease of understanding, the application scenario in which the target device is a projection imaging device in a vehicle cabin is described as follows:
for convenience of description, an electronic device is taken as a head-up display device, and the projection imaging apparatus is taken as a front windshield of a vehicle as an example. After the head-up display device projects the vehicle information onto the front windshield, the driver looks at the vehicle information display area on the front windshield if he wishes to understand some of the vehicle information presented on the front windshield while he is driving the vehicle.
In practical applications, since the vehicle information display area on the front windshield is located in front of the driver, the line of sight of the driver may also unintentionally scan the vehicle information display area during normal driving of the vehicle, in which case, if it is detected that the line of sight of the driver looks at the first display image in the vehicle information display area, the display parameters are adjusted, which may result in erroneous adjustment.
And if the driver wishes to view the specific information displayed in the vehicle information display area of the front windshield, the driver is necessarily concerned about the accumulated time period of the first display image of the vehicle information display area in a short time period is relatively long. Alternatively, after the driver looks at the first display image in the vehicle information display area at a glance, the driver may temporarily remove the line of sight from the first display image for driving safety, but if the driver wishes to understand the vehicle information in the first display image, the driver may look at the first display image again in a short time, so that the time in which the driver's line of sight looks at the first display image in a short time reaches the first set period.
Therefore, the accumulated time of the sight line of the driver looking at the first display image exceeds the first set time, and the vehicle information in the first display image which the driver hopes to know can be determined more accurately.
In a second possible case, the display parameters are adjusted upon determining that the total number of times the first display image is gazed by the observer within the set time reaches the set number of times.
In this possible case, the setting time may also be set as needed, without limitation.
The number of settings may be set as desired, for example, the number of settings may be a natural number greater than or equal to 2.
Similarly to the first possible case, if the observer confirms that it is desired to know the information in the first display image, the observer will necessarily look at the first display image again or multiple times in a short time without clearing or completing the understanding of the content of the first display image. In the aforementioned vehicle driving scenario, the driver may be able to see a certain part of the information in the vehicle information display area of the front windshield more than once.
In this way, the number of times the first display image is watched by the observer in the set time reaches the set number of times, and the display parameters are adjusted, so that the situation that the observer carelessly looks at the first display image and the display parameters are triggered and adjusted by mistake can be reduced.
In a third possible case, the display parameter is adjusted upon determining that the continuous length of time for which the first display image is gazed by the observer reaches the first set length of time.
Wherein the continuous period of time during which the observer looks at the first display image means a total period of time from when the observer starts looking at the first display image to when the line of sight of the observer is displaced from the first display image.
The first set time period in this third possible case may be the same as the first set time period in the previous first possible case, but may be different, without limitation.
It can be appreciated that if the observer wants to view the information in the first display image, the observer is necessarily required to continuously watch the first display image for a period of time, otherwise, the observer does not want to know the information in the first display image, based on this, when the continuous time period for confirming that the first display image is watched by the observer reaches the first set time period, the situation of misjudgment can be effectively reduced by adjusting the display parameters.
It can be understood that in practical application, the application can trigger and adjust the display parameters under any condition of meeting the three conditions; the adjustment of the display parameter may be triggered in the case where two or more of the above three cases are satisfied, without limitation.
It will be appreciated that in a third possible scenario, the observer continues to look at the first display image for a period of time, and if the observer does not fully or clearly understand the information in the first display image, the observer may still look at the first display image again after removing his line of sight from the first display image.
In this case, in order to adjust the display parameters in time so that the display effects of the first display image and the second display image are different, the present application may adjust the display parameters by only annotating the first display image for a short time after the line of sight of the observer looks at the first display image again. One implementation procedure of the display control method of the present application is described below in connection with this third possible case.
As shown in fig. 2, which is a schematic flow chart of a display control method provided in an embodiment of the present application, the method of the present embodiment may include:
s201, determining a first display image watched by an observer on a target device.
Wherein the first display image and the second display image are viewable by a viewer from the target device.
The target device is capable of being penetrated by visible light.
This step may be referred to in the description of the previous embodiments and will not be described in detail here.
S202, when the continuous time period of the first display image watched by the observer reaches the first set time period, adjusting the display parameters so that the first display image and the second display image show different display effects.
In one alternative, the viewer's line of sight is detected to be away from the first display image, and the adjusted display parameters are restored to the pre-adjustment display parameters so that the first display image and the second display image exhibit the same display effect.
And S203, after detecting that the line of sight of the observer moves out of the area corresponding to the first display image, if the observer is detected to watch the first display image and the continuous time of watching the first display image reaches a second set time, adjusting display parameters so that the first display image and the second display image show different display effects.
The second set duration is smaller than the first set duration.
The display parameter adjusted in step S203 may be the same as or different from the display parameter adjusted in step S202, so long as it is ensured that the first display image and the second display image exhibit different display effects by adjusting the display parameter.
It will be appreciated that when the duration of the continuous gaze of the observer at the first displayed image reaches the first set duration, this indicates that the observer wishes to view information of the first displayed image. On this basis, if the observer looks at the first display image again after the line of sight of the observer moves out of the area corresponding to the first display image, it is stated that the observer still has a need to continue to view the information in the first display image.
Based on this, in order to control the first display image and the second display image to present different effects in time, the waiting time can be reduced, namely after the continuous time that the observer looks at the first display image again reaches a set time shorter than the first set time, the display parameter is triggered to be adjusted again, so that the first display image and the second display image can be controlled to present different display effects in time, and the requirement that the observer looks at the first display image more clearly can be met more efficiently.
To facilitate understanding of the benefits of the present embodiment, taking a vehicle information display scenario as an example, it is assumed that the head-up display device controls the projection device to project vehicle information to the front windshield, and that the first set duration is 1 second and the second set duration is 500 milliseconds, and that the first display image is a first vehicle information area in the vehicle information display area of the front windshield, and the second display image is a vehicle information area other than the first vehicle information area in the vehicle information display area as an example.
In the driving process of the driver, if the sight of the driver looks at a first vehicle information area in the vehicle information display area of the front windshield and the continuous time of looking at the first vehicle information area is detected to be 1 second, the driver can be determined to have the requirement of looking at the first vehicle information area, and the display parameters can be adjusted so that the first vehicle information area and the second vehicle information area have different display effects.
After the driver's line of sight is removed from the first vehicle information area, the display parameters may be restored to the pre-adjustment display parameters so that the display effect of the first vehicle information area is the same as that of the second vehicle information area. On this basis, if the driver's line of sight is gazed again at the first vehicle information area, the display parameters may be readjusted so that the display effect of the first vehicle information area is different from that of the second vehicle information area only when the duration of the driver's gazing again reaches 500 milliseconds.
Of course, after the driver's sight is moved away from the first vehicle information area, the display parameters before adjustment may not be restored, and only after the driver looks at the first vehicle information area again for 500 milliseconds, the display parameters may be adjusted again so that the display effect of the first vehicle information area is different from that of the second vehicle information.
In any of the above embodiments of the present application, a specific implementation of adjusting the display parameters of the first display image or the second display image may be possible.
The following description will take, as an example, adjustment of at least one of display brightness, display color, and image size of the first display image or the second display image.
The first display image and the second display image can have different display effects through at least one of the following three implementation modes:
in a first possible implementation, the display brightness of the first display image may be adjusted from a first display brightness to a second display brightness, the second display brightness being higher than the first display brightness. Or, the display brightness of the second display image is adjusted from the third display brightness to a fourth display brightness, and the fourth display brightness is lower than the third display brightness.
The first display brightness is the original brightness of the first display image when the observer looks at the first display image, and the second display brightness is the adjusted display brightness. Similarly, the fourth display luminance is the luminance after the second display image is adjusted, and the third display luminance is the luminance before the second display image is adjusted.
It can be appreciated that by dimming the display brightness of the first display image or dimming the display brightness of the second display image, the brightness of the first display image relative to the second display image can be brighter, which is beneficial to highlighting the first display image, so that an observer can more accurately position the first display image, and the influence of information in surrounding display images on the observer can be reduced in the process that the observer views the information in the first display image.
In a second possible implementation, the display color of the first display image may be adjusted from a first color to a second color, where the sharpness of the second color is higher than the sharpness of the first color. Or, adjusting the display color of the first display image from a third color to a fourth color, wherein the sharpness of the fourth color is lower than that of the third color.
The definition of a color is also called brightness or luminance, and refers to the brightness of the color.
In this implementation, the display color of the first display image is increased or the display color of the second display image is decreased, so that the first display image can be highlighted, which is beneficial for a user to capture information in the first display image more accurately.
In a third possible implementation, the first display image is enlarged or the second display image is reduced.
The enlarging of the first display image may be enlarging the entire first display image or enlarging a character portion in the first display image.
Similarly, the second display image may be reduced in size, or the text portion in the second display image may be reduced.
It can be appreciated that by enlarging the first display image or reducing the second display image, an observer can pay more attention to the information in the first display image more accurately, which is beneficial to reducing interference caused by the second display image to the observer's viewing of the first display image, and is beneficial to capturing the information in the first display image more efficiently and accurately.
It should be understood that the foregoing is illustrative of several possible implementations of adjusting the display parameters of the first display image or the second display image, and in practical applications, the present application may also enable the first display image to have a different display effect from the second display image by setting a dynamic effect capable of highlighting the first display image for the first display image, such as adding a bright line at an edge of the first display image.
Of course, there may be other implementations that make the display effects of the first display image and the second display image different, and this is not limited.
In order to facilitate understanding of the solution of the embodiment of the present application, the following description will be given with reference to an application scenario, and a specific implementation is taken as an example, and a target device is taken as a projection imaging device in a vehicle cabin as an example.
As shown in fig. 3, which is a schematic flow chart of a display control method provided in an embodiment of the present application, the method of the present embodiment may include:
s301, determining a first display image focused by an observer on a projection imaging apparatus in a vehicle cabin.
The projection imaging device is used for presenting the vehicle information projected by the projection device.
For example, the projection imaging apparatus is a transparent display in the vehicle cabin connected to the head-up display device by wire or wirelessly. As another example, the projection imaging apparatus may be a front windshield of a vehicle.
Wherein the first display image and the second display image can be observed by an observer from a vehicle information display area of the projection imaging apparatus. The first display image and the second display image belong to an image of the vehicle information presented in the projection imaging apparatus.
The vehicle information display area of the projection imaging device is an area for presenting the vehicle information projected by the projection device, for example, the projection imaging device is a transparent display, and the vehicle information display area is a display area of the transparent display; if the projection imaging apparatus is a front windshield, the vehicle information display area is an area for presenting vehicle information in the front windshield.
For example, taking an observer as a driver of a vehicle as an example, an eye image of the driver may be captured by an image capturing device. If it is determined that the driver's line of sight is in the vehicle information display area of the projection imaging apparatus based on the eye image, a first display image in the vehicle information display area at which the driver gazes may be determined based on a point of gaze position of the driver's line of sight in the vehicle information display area. For example, an image area within the gaze location point setting range is determined as the first display image.
S302, when the continuous time period of the first display image watched by the observer reaches the first set time period, at least one of display brightness, display color and image size of the first display image or the second display image is adjusted, so that the first display image and the second display image show different display effects.
If the continuous time period for the driver to continuously watch the first display image reaches the first set time period, which indicates that the driver wants to watch the vehicle information in the first display image, at least one of the display brightness, the display color and the image size of the first display image or the second display image can be adjusted.
The adjusting of the display brightness, display color and image size of the first display image or the second display image may be referred to in the related description of the foregoing embodiments, and will not be described herein.
For example, assuming that the first display image displays navigation information of the vehicle and the second display image is related information such as weather, when the driver continuously looks at the navigation information for a first set period of time, the font or the whole image size in the navigation information can be increased by brightening the interface brightness of the navigation information, so that the driver can see the navigation information more clearly and accurately.
Of course, this step S302 is merely taken as an example of an implementation manner of adjusting the display parameters so that the display effects of the first display image and the second display image are different, and in practical application, the aforementioned specific implementation manner of adjusting the display parameters is also applicable to the present embodiment, which is not limited thereto.
S303, adjusting early warning parameters of the vehicle in response to the operation of adjusting the display parameters so as to improve the risk early warning level of the vehicle.
The early warning parameters of the vehicle are parameters related to the risk early warning of the vehicle, and the risk early warning level of the vehicle can be changed by adjusting the early warning parameters of the vehicle.
The risk early warning of the vehicle refers to a function of outputting an alarm by the vehicle when the risk of the vehicle is confirmed.
For example, the risk alarm of the vehicle can comprise that the distance between the vehicle and the front vehicle is smaller than a set distance, and an early warning that the distance between the vehicle and the front vehicle is too small is output.
As another example, the risk alert of the vehicle may include a vehicle overspeed alert output by the vehicle when the speed of the vehicle exceeds a limit speed of the travel path.
As another example, the risk alert of the vehicle may also include a risk alert of a hazard or congestion ahead of the travel section of the vehicle.
In the present application, the display parameters are adjusted only when it is determined that the observer looks at the vehicle information displayed by the projection imaging apparatus in the vehicle cabin. Based on the above, the adjustment of the display parameter can indicate that the current line of sight of the observer such as the driver stays in the vehicle information displayed by the projection imaging device, so as to ensure driving safety and enable the observer to watch the vehicle information displayed by the projection imaging device more stably and reliably.
The pre-warning parameters adjusted in the application can be one or more, and are not limited.
To facilitate an understanding of the benefits of triggering adjustment of the alert parameters while the electronic device adjusts the display parameters, an example is described.
Taking the example that the driver looks at the vehicle information displayed by the projection imaging device in the vehicle compartment during the driving of the vehicle, when the driver looks at the front windshield or the vehicle information presented on the transparent display, the driver's perception of the surrounding environment of the vehicle is reduced, and it is likely that the driver cannot respond in time when an emergency occurs.
Based on this, this application can promote the risk early warning grade of vehicle through the early warning parameter of adjustment vehicle to can remind the driver in time that the vehicle probably exists danger.
For example, taking a vehicle distance risk early warning as an example, when the driver does not look at the vehicle information displayed by the projection imaging device, the vehicle distance risk early warning may be of a common level, and in this case, if the vehicle distance from the preceding vehicle is less than 50 meters, a risk warning that the vehicle distance is too small is output. And under the condition that the driver is confirmed to watch the vehicle information displayed by the projection imaging device, if the display parameters are adjusted, the level of the vehicle distance risk early warning is triggered to be increased to a high early warning level, and under the condition that the vehicle distance from the front vehicle is less than 100 meters, the risk warning of the vehicle distance being too small is output.
Of course, risk early warning for other vehicles is similar, and will not be described again.
It will be appreciated that this step S303 is an optional step, and this step S303 may or may not be performed in actual applications as desired.
