Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The embodiment of the application can be applied to electronic equipment, the application does not limit the product form of the electronic equipment, and the product form can comprise but is not limited to smart phones, tablet computers, wearable equipment, personal computers (personal computer, PC), netbooks and the like, and can be selected according to application requirements.
Fig. 1 is a flowchart of a control method for display according to an embodiment of the present application. Referring to fig. 1, the control method shown may include:
step 101: the method comprises the steps of acquiring states of an image acquisition unit and display time sequence signals of a display screen, wherein the display screen comprises a first display area and an image acquisition unit, the image acquisition unit is located at a position corresponding to the first display area, and the display time sequence signals comprise a first time interval and a second time interval which are alternately continuous.
The electronic equipment to which the display control method is applied comprises an image acquisition unit and a display screen, wherein the image acquisition unit can be an under-screen camera, is arranged below the display screen, and corresponds to the first display area in position; thus, from the appearance point of view, the user is not able to see the presence of the image acquisition unit, but is able to see only one complete display screen. When the image acquisition unit acquires an image, a first display area of the display screen corresponding to the image acquisition unit is actually in a transparent state, so that the image acquisition unit can acquire external image information through the first display area in the transparent state.
In this embodiment, the image capturing unit state may include an operating state and a non-operating state. After the state of the image acquisition unit is determined, it is possible to clearly determine how to control the display screen so that the image acquisition unit can complete the image acquisition task. In particular, how the image acquisition unit acquires the image will be described in detail in the following embodiments, and will not be described here.
The time sequence signals of the display screen are used for controlling the display tasks of the display screen, and the lengths of different time sequence intervals in the time sequence signals are related to the refresh rate of the display screen. Fig. 2 is a schematic diagram of a display timing signal according to an embodiment of the present application. Referring to fig. 2, in the high level time sequence section, the corresponding light in the display screen is lighted, and an image is displayed on the display screen; and the low level time sequence section, the light in the display screen is closed; the high level time sequence section and the low level time sequence section are interactively continued, so that refreshing and displaying of the image frames are realized. It should be noted that, due to the persistence of vision characteristic of human eyes, when the refresh rate of the display screen reaches a specific value, even if the light in the display screen is turned off, the human eyes cannot sense the light; the display screen is therefore always in a lit state in the perception of the user. And the current general display screen can reach the condition of the specific numerical value. In the embodiment of the application, one of the first time interval and the second time interval corresponds to a low level time sequence period and the other corresponds to a high level time sequence period.
Step 102: if the image acquisition unit is in a working state, the image acquisition unit acquires an image in a first time interval; and in a second time interval, the display screen displays a frame picture, and the image acquisition unit stops acquiring images.
When the image acquisition unit is in a working state, the image acquisition unit has an image acquisition task. The image acquisition unit can only be completed when the first display area of the display screen is turned off, and based on the working principle of the display screen, in this embodiment, the image acquisition unit can be controlled to execute the image acquisition task when the display screen is in a low-level time sequence section, that is, when the display screen is not lighted by light and the display screen is in a transparent state, so that the normal display task of the display screen is not affected, and the image acquisition task can be completed. In this embodiment, the first time interval corresponds to a time period in which the display is at a low level. Thus, the display timing of the display screen is divided into two parts as a whole, namely, the display timing and the sampling timing of the image acquisition unit, and the two timings alternately occur at intervals. Wherein,
Fig. 3 is a corresponding relationship diagram of display timing of a display screen and operation timing of an image acquisition unit according to an embodiment of the present application, and the implementation of the present application can be understood with reference to fig. 3.
Fig. 4 is a graph showing the comparison of the effects of the display screen in the image acquisition process of a solution and an embodiment of the application. In connection with fig. 4, in one solution, the camera part always presents a black hole (upper middle position) when the image acquisition unit works, but in the solution of the application, no matter whether the image acquisition unit works or not, the complete display content is always presented on the display screen, and the starting of the image acquisition function is not perceived by the user. Compared with the traditional scheme that the display function of the corresponding area is closed when the image acquisition unit works, the method and the device for acquiring the image have the advantages that the watching experience of the user is not affected in the process of acquiring the image, and the satisfaction degree of the user can be improved.
According to the control method for displaying, the image acquisition unit is controlled to acquire images through the transparent display screen in the time sequence section corresponding to the extinction of the backlight on the display screen, and the image acquisition unit is controlled to stop acquiring the images in the time sequence section corresponding to the illumination of the backlight on the display screen, so that the display screen can normally perform a display task, the image acquisition of the image acquisition unit is realized on the premise that the full-screen display effect of the display screen is not affected, the use of a user is greatly facilitated, and compared with the realization of black holes in the corresponding area when the camera works under the traditional screen, the use experience of the user is greatly optimized.
In other implementations, the method of controlling display may further include a step of determining a section length of the first time section and the second time section, in addition to the steps disclosed in the foregoing embodiments. The interval length of the first time interval and the interval length of the second time interval may be the same or different.
In particular, the interval length of the first time interval and the second time interval may be dynamically determined based on the environmental attribute and/or the attribute of the image acquisition unit. Wherein the environmental attribute includes ambient light level, and the attribute of the image acquisition unit includes a shutter type or exposure time.
It will be appreciated that for a fixed image acquisition unit, the resources required to acquire images are also different in different circumstances. For example, in a scene where ambient light is darker, more exposure time is often required to acquire a clearer image; in an environment where the ambient light is relatively bright, the image acquisition unit is able to complete the exposure of the image in a relatively short time. Therefore, based on different environmental attributes, the time required by the image acquisition unit to acquire the image is also different, so that the length of the first time interval can meet the requirement of the image acquisition unit to acquire the image by determining the distribution of the interval lengths of the first time interval and the second time interval in the embodiment of the application.
For example, for a display screen with a 120HZ refresh rate, one high level timing period is 1/120 of a second and one low level timing period is 1/120 of a second; if in a brighter environment, the normal time sequence signals can be adopted, namely the time sequence signals with the same time length of the high level time sequence section and the low level time sequence section; in an environment where the ambient light is relatively dark, the high level timing period may be set to 0.7/120 seconds, and the low level timing period may be set to 1.3/120 seconds. Therefore, the refresh rate of the display screen is unchanged, but the time limit allocated to the image acquisition unit for acquiring the image is long, so that the image acquisition requirement in the dark environment can be met.
The attribute dynamics of the image acquisition unit may include, but is not limited to, the shutter type of the image acquisition unit. It is well known to those skilled in the art that the exposure time required for the global shutter to acquire an image is shorter, and the exposure time required for the rolling shutter to acquire an image is longer, so that the interval length of the first time interval and the second time interval can be allocated and determined according to the shutter type of the image acquisition unit.
The foregoing implementation of time allocation between the first time interval and the second time interval may be an implementation of dynamic allocation. That is, the lengths of the first time interval and the second time interval are dynamically allocated as the environmental attribute changes or the configuration of the attribute dynamics of the image acquisition unit changes. Taking the example of dynamic allocation of interval length based on environmental attributes, the main logic is: under the condition that the image acquisition unit judges the dim light, more time is allocated to the image acquisition unit; in the case of bright light, the same or more times are allocated to the screen display (corresponding to the time at which the screen light is lit).
In a specific implementation, determining the interval lengths of the first time interval and the second time interval can be seen in fig. 5. As shown in connection with fig. 5, the determining the interval length of the first time interval and the second time interval based on the environmental attribute and/or the attribute of the image acquisition unit may include:
step 501: a first time interval and a second time interval of a display timing signal of the first display area are determined based on a first refresh rate of the first display area.
Step 502: a section length of the first time section and the second time section is determined based on an environmental attribute and/or an attribute of the image acquisition unit.
That is, based on the first refresh rate of the first display area, a total time period for refreshing the display screen for one frame is first determined, and then, in the determined time period, what the duty ratio of the first time interval is, and what the duty ratio of the second time interval is.
The determining the interval lengths of the first time interval and the second time interval of the first display timing signal based on the environmental attribute and/or the attribute of the image acquisition unit may include: and when the ambient light brightness is lower than a first threshold value and/or the exposure time of the image acquisition unit is higher than a second threshold value, increasing the frame length duty ratio of the first time interval, wherein the sum of one first time interval and one second time interval is one frame length.
In one implementation, the display screen further includes a second display area, where the second display area is another display area of the display screen except for the first display area, such as another display area except for a black hole (a first display area corresponding to the camera) in fig. 4. The control method of the display may further include: a first refresh rate of the first display region and a second refresh rate of the second display region are determined based on a state of the image acquisition unit.
It can be understood that, under the condition that the refresh rate of the display screen is higher, the time for refreshing one frame of image is shorter, so that the time which can be allocated to the image acquisition unit for image acquisition in the time for refreshing one frame of image is shorter, and the situation that the image acquisition requirement cannot be met may occur.
In combination with the above, in view of the fact that the first display area corresponding to the image acquisition unit itself is small, a design in which the refresh rates of the first display area and the second display area are different may be set. In a specific implementation, the refresh rate of the first display area can be reduced, so that the time limit of refreshing one frame of image in the first display area can be prolonged, and the time for image acquisition can be allocated to the image acquisition unit in the time of refreshing one frame of image, and the effect of completing image acquisition under the condition of not affecting normal display is also realized. Because the first display area is smaller, the refresh rate of the first display area is lower than that of the peripheral second display area in time, and the first display area is difficult to identify for a corresponding user, so that the viewing experience is not affected.
Fig. 6 is a schematic diagram of an operation implementation principle of different refresh rates of a display screen according to an embodiment of the present application, which can be understood with reference to fig. 6.
Thus, the determining the first refresh rate of the first display area and the second refresh rate of the second display area based on the state of the image acquisition unit may include: if the image acquisition unit is in a first state (the corresponding image acquisition unit is in a closed state), determining that the first display area and the second display area have the same refresh rate; if the image acquisition unit is in a second state (the corresponding image acquisition unit is in a working state), determining that the first display area has a first refresh rate, the second area has a second refresh rate, and the first refresh rate is different from the second refresh rate.
In practical applications, the first refresh rate may be greater than the second refresh rate or less than the second refresh rate, which is not limited by the present application. The basis for adjusting the refresh rate includes, but is not limited to, factors such as ambient light level, type of shutter of the image acquisition unit, and the like.
In one implementation, a method of determining the first refresh rate may include: and reducing the first refresh rate of the first display area from a first value to a second value in the case that the ambient light level is below a first threshold and/or in the case that the exposure time of the image acquisition unit is greater than a second threshold.
Also, in case the ambient light level is below a first threshold and/or in case the exposure time of the image acquisition unit is above a second threshold, the image acquisition unit needs more time to acquire the image, and thus the first refresh rate of the first display area may be reduced to enable the image acquisition unit to allocate more image acquisition time.
It should be noted that, the image acquisition unit further includes an image acquisition state and a stop acquisition state in the working state; the image acquisition state corresponds to the state that the first display area is in the first time interval, and the acquisition stopping state corresponds to the state that the first display area is in the second time interval. That is, in the first time interval, the light in the display screen is extinguished, and the image acquisition unit acquires an image through the transparent first display area; and in a second time interval, the light in the display screen is lightened, and the image acquisition unit stops acquiring images. The image acquisition unit can be in a power-down state when in a stop acquisition state, or can be in a power-on but non-working state.
In the above embodiment, the image acquisition unit needs to perform image acquisition in a low-level time sequence segment in the time sequence signal of the display screen, so in practical application, it is required to realize time sequence synchronization of the image acquisition unit and the display screen. Specifically, a preset synchronizing signal can be used to coordinate between the display screen and the image acquisition unit, so as to accurately agree on the key time sequence points of the alternate work. That is, timing synchronization of the first display area and the image acquisition unit is achieved by synchronizing timing signals. Fig. 7 is a schematic diagram of a hardware architecture for controlling timing synchronization of a display screen and an image acquisition unit according to an embodiment of the present application. With reference to fig. 7, a display control chip for controlling a display screen may trigger sending a display/sampling synchronization timing signal to a camera image sensor (i.e., the image acquisition unit) when each high-low level conversion is performed, so as to ensure that the work distribution time of the image acquisition unit and the display screen can be accurately matched, and ensure that the image acquisition unit can normally complete an image acquisition task.
