The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The mobile terminal according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, which have wireless communication functions, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and the like. For convenience of description, the above-mentioned devices are collectively referred to as a mobile terminal.
The following describes embodiments of the present application in detail.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for adjusting display parameters according to an embodiment of the present disclosure, and as shown in fig. 1, the method for adjusting display parameters includes the following steps.
101, when the mobile terminal is in an automatic display parameter adjusting mode, if the number of detection parameters maintained by a detection parameter sequence reaches N, the mobile terminal selects a target detection parameter from the detection parameter sequence; n is an integer greater than or equal to 2.
In the embodiment of the present application, the display parameter may include a backlight brightness or a backlight color temperature. The display parameter auto-adjustment mode may include a backlight brightness auto-adjustment mode or a backlight color temperature auto-adjustment mode.
The detection parameter may comprise a light sensitivity value or a color temperature value.
The mobile terminal can monitor the light sensing value through the light sensor and can monitor the color temperature value through the color temperature sensor.
The optical sensor may also be referred to as a light sensor or an ambient light sensor. The light sensor may be disposed on a front panel of the mobile terminal or may be disposed under a display screen (i.e., light sensing under the screen). The light sensor is used for detecting the light sensation value of the environment where the mobile terminal is located. The light sensation value can be expressed in lux.
The color temperature sensor can be arranged on the front panel of the mobile terminal and can also be arranged under the display screen (namely, the color temperature sensor under the screen). The color temperature sensor is used for detecting the color temperature value of the environment where the mobile terminal is located. Both the color temperature value and the backlight color temperature can be expressed in kelvin (K).
In the backlight brightness automatic adjustment mode, the mobile terminal can determine the backlight brightness of the mobile terminal according to the target backlight brightness curve; in the backlight color temperature automatic adjustment mode, the mobile terminal may determine the backlight color temperature of the mobile terminal according to the target backlight color temperature curve. The target backlight luminance profile may be an automatic backlight luminance profile or a backlight luminance profile determined based on a manual adjustment recording on the basis of the automatic backlight luminance profile. The target color temperature luminance curve may be an automatic color temperature luminance curve, or may be a color temperature luminance curve determined based on a manual adjustment record on the basis of the automatic color temperature luminance curve.
The backlight brightness of the mobile terminal can be set to be in a backlight brightness automatic adjusting mode or in a backlight brightness manual adjusting mode. In the backlight brightness automatic adjustment mode, the backlight brightness of the mobile terminal may be adjusted according to the change of the obtained ambient light intensity, or may be manually adjusted by the user on the basis of automatic adjustment, and when the automatic adjustment conflicts with the manual adjustment, the manual adjustment is generally used as the standard. In the manual adjustment mode, that is, in the case that the user closes the automatic adjustment, the backlight brightness of the mobile terminal is manually set by the user, and once the backlight brightness is set, the backlight brightness of the mobile terminal is fixed.
The backlight brightness of the mobile terminal can be controlled by a display module, and the display module of the mobile terminal generally includes: the display screen (such as a liquid crystal display screen, an LED display screen, an OLED display screen and the like), the backlight source (such as an LED backlight source), the driving circuit, the connecting piece and the control circuit. For a liquid crystal display screen or an LED display screen, the backlight source is positioned at the back of the display screen, the display screen does not emit light, and the display screen displays graphs or characters which are the result of modulating light generated by the display module group to the backlight source. For a liquid crystal display or LED display, the backlight generally includes a light source (e.g., an LED lamp), a light guide plate (e.g., the light guide plate may be made of acrylic material), an optical film, and a plastic frame. The light source is provided with a light guide plate, and the light guide plate is provided with an optical film. The light guide plate and the optical film can convert light generated by the light source into uniform light. In the embodiment of the present application, adjusting the backlight brightness of the mobile terminal mainly refers to adjusting the brightness of a backlight source.
In the manual backlight brightness adjusting mode, a user can adjust the backlight brightness of the mobile terminal by dragging the backlight progress bar of the mobile terminal.
The size of N may be fixedly set, for example, N is set to a fixed value, for example, the fixed value may be 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and the like. The size of N can also be flexibly set. For example, the magnitude of N may be set according to a historically determined trend of the steady detection parameter. For example, the historically determined stable detection parameters are a1, a2, A3 in order, and the current stable detection parameter is a 4. If A1 < A2 < A3 < A4, then N may be set equal to 8; if A1 > A2 > A3 > A4, then N may be set equal to 12. A relatively small value of N may be set if the trend of change of the historically determined stable detection parameter is increasing, and a relatively large value of N may be set if the trend of change of the historically determined stable detection parameter is decreasing.
The sensed parameter sequence is a set of sensed parameters sensed by the sensed parameter sensor over a period of time. The sequence of detection parameters may be in the form of a queue. The head of the queue is the detection parameter of the first entering queue, and the tail of the queue is the detection parameter of the latest entering queue. The length of the queue may be set to N, that is, the number of the most allowed elements (i.e., detection parameters) of the queue is N, and the embodiments of the present application relate to the selection of elements in the queue and do not relate to the dequeuing of the queue.
The detection parameter sensor may include a light sensor or a color temperature sensor. The detection parameter sensor may periodically detect a detection parameter of the mobile terminal, and periodically report the detected detection parameter to the mobile terminal (e.g., a processor of the mobile terminal or a device for adjusting a display parameter). The detection period of the detection parameter sensor is 10-1000 ms. For example, the time period may be any one of 100ms, 200ms, 300ms, 400ms, 500ms, 600ms, 700ms, 800ms, 900ms, and 1000ms, and the embodiment of the present application is not limited thereto. The mobile terminal can screen the detection parameters reported by the detection parameter sensor according to preset conditions, and add the detection parameters meeting the preset conditions into the detection parameter sequence. When the number of the detection parameters in the detection parameter sequence reaches N, the mobile terminal performs the step of selecting the target detection parameter from the detection parameter sequence in step 101, and after performing step 101, the detection parameter sequence may be cleared. After emptying the detection parameter sequence, the mobile terminal may still continue to screen the detection parameters reported by the detection parameter sensor, add the detection parameters meeting the preset conditions into the detection parameter sequence, and execute the step of selecting the target detection parameter from the detection parameter sequence in step 101 until the number of the detection parameters in the detection parameter sequence reaches N. The above steps are repeated.
Optionally, the mobile terminal selects the target detection parameter from the detection parameter sequence, which may specifically include the following steps:
the mobile terminal selects the detection parameter with the largest value from the detection parameter sequence as a target detection parameter; alternatively, the first and second electrodes may be,
the mobile terminal selects a detection parameter with the minimum absolute value of the difference value with the last stable detection parameter from the detection parameter sequence as a target detection parameter, and the last stable detection parameter is the stable detection parameter determined last time; alternatively, the first and second liquid crystal display panels may be,
the mobile terminal selects a detection parameter with the second largest value from the detection parameter sequence as a target detection parameter; alternatively, the first and second liquid crystal display panels may be,
and the mobile terminal selects the detection parameter with the second smallest absolute value of the difference value with the last stable detection parameter from the detection parameter sequence as the target detection parameter.
The last stable detection parameter may be a stable detection parameter determined when the number of detection parameters maintained at one time in the detection parameter sequence reaches N.
The mobile terminal may select a target detection parameter from the detection parameter sequence according to a preset policy, where the preset policy may be one of a maximum policy, a second maximum policy, a closest policy, and a second near policy. Wherein, the maximum value strategy is as follows: and selecting the detection parameter with the largest value from the detection parameter sequence as a target detection parameter. The second major strategy is: and selecting the detection parameter with the second largest value from the detection parameter sequence as the target detection parameter. Recent strategies: and selecting the detection parameter with the minimum absolute value of the difference value with the last stable detection parameter from the detection parameter sequence as the target detection parameter. The second near strategy is as follows: and selecting the detection parameter with the second smallest absolute value of the difference value with the last stable detection parameter from the detection parameter sequence as the target detection parameter. And the last stable detection parameter is the stable detection parameter determined when the number of the detection parameters maintained at one time on the detection parameter sequence reaches N.
For example, if N equals 8, the last stable detection parameter is 560. The currently maintained 8 detection parameters of the detection parameter sequence are respectively: 576. 570, 587, 593, 585, 574, 566, 579. The target detection parameter is 593 if the maximum strategy is employed, 587 if the second largest strategy is employed, 566 if the most recent strategy is employed, and 570 if the second closest strategy is employed.
And 102, the mobile terminal determines the target detection parameter as the current stable detection parameter of the detection parameter sequence.
In the embodiment of the present application, when the number of the detection parameters maintained by the detection parameter sequence reaches N, a target detection parameter is selected from the number of the detection parameters to serve as a current stable detection parameter of the detection parameter sequence. After determining the current stable detection parameters of the detection parameter sequence, the mobile terminal will empty the detection parameter sequence, and count the detection parameters maintained by the parameter sequence again until the number of the detection parameters maintained by the parameter sequence reaches N, from which the next stable detection parameters are determined. And after determining the next stable detection parameter, emptying the detection parameter sequence, and counting the detection parameters maintained by the parameter sequence again. The above steps are repeated.
And 103, the mobile terminal calculates target display parameters corresponding to the current stable detection parameters according to a target display parameter curve, the current display parameters of the mobile terminal are adjusted to the target display parameters, and the target display parameter curve is determined based on the display parameter automatic adjustment mode.
In the embodiment of the present application, the target display parameter curve may be an automatic display parameter curve, or may be a manual display parameter curve determined based on a manual adjustment record on the basis of an automatic display parameter curve.
Referring to fig. 2a, fig. 2a is a schematic diagram illustrating an automatic parameter curve display according to an embodiment of the present disclosure; as shown in fig. 2a, the abscissa of the automatic display parameter curve is the detection parameter detected by the detection parameter sensor, and the ordinate is the display parameter. If the mobile terminal starts the automatic display parameter adjusting mode, the display parameters of the mobile terminal can be adjusted according to the automatic display parameter curve.
As can be seen from fig. 2a, if the current stable detection parameter is a1, and the target display parameter corresponding to the automatic display parameter curve of a1 is b1, the current display parameter of the mobile terminal may be adjusted to be the target display parameter b 1. If the current stable detection parameter is a2, and the target display parameter corresponding to the a2 on the automatic display parameter curve is b2, the current display parameter of the mobile terminal may be adjusted to the target display parameter b 2.
Furthermore, in order to avoid the influence of repeated changes of display parameters on user experience, an anti-shaking interval is generally set, and the display parameters are kept stable in the anti-shaking interval. For example, in the anti-shake section shown in fig. 2a, when the detected parameter falls into the anti-shake section, the display parameter is fixed to b 1.
If the display parameter is the backlight brightness, the detection parameter is the light sensing value, the detection parameter sensor is the light sensor, and the automatic display parameter curve is the automatic backlight brightness curve. The backlight brightness can be expressed in a proportional value of the maximum backlight brightness that can be provided by the backlight source of the mobile terminal. For example, if the backlight brightness is 100%, it represents that the backlight brightness is 100% of the maximum backlight brightness that can be provided by the backlight source of the mobile terminal; if the backlight brightness is 60%, it means that the backlight brightness is 60% of the maximum backlight brightness that the backlight source of the mobile terminal can provide. For example, if the light sensation value is in the anti-shake interval (e.g., 100-500 lux), the corresponding backlight brightness is 40%.
If the display parameter is the backlight color temperature, the detection parameter is the color temperature value, the detection parameter sensor is the color temperature sensor, and the automatic display parameter curve is the automatic backlight color temperature curve. For example, if the color temperature value is in the anti-shake range (e.g., 2000-3000K), the corresponding backlight color temperature is 2500K.
The anti-shake interval may be set as needed, or may be set as one or more intervals, which is not limited in the embodiments of the present application.
Referring to fig. 2b, fig. 2b is a schematic diagram of a manual parameter curve display disclosed in the embodiment of the present application; as shown in fig. 2b, the top left diagram is an automatic display parameter graph, and the bottom left diagram, the top right diagram, and the bottom right diagram are manual display parameter graphs generated based on three different historical manual adjustment records, respectively. In the figure, the abscissa is a detection parameter, the ordinate is a display parameter, the curve with thinner lines is an automatic display parameter curve, and the curve with thicker lines is a manual display parameter curve. Black points in the automatic display parameter curve graph and the manual display parameter curve graph are historical manual adjustment records, each black point represents one historical manual adjustment record, the abscissa of each black point represents the detection parameter corresponding to the time point of the historical manual adjustment record, and the ordinate of each black point represents the display parameter of user adjustment recorded in the historical manual adjustment record. P1, P2, and P3 in fig. 5 represent three historical manual adjustment records, respectively (P1 is the historical manual adjustment record when the detection parameter is a1, P2 is the historical manual adjustment record when the detection parameter is a2, and P3 is the historical manual adjustment record when the detection parameter is a 3). The top right graph represents the manual display parameter graph generated based on P1, the bottom left graph represents the manual display parameter graph generated based on P2, and the bottom right graph represents the manual display parameter graph generated based on P3.
When a manual display parameter curve is adopted, a historical manual adjustment record closest to the current detection parameter can be selected from historical manual adjustment records, and the manual display parameter curve is generated based on the historical manual adjustment record closest to the current detection parameter and the automatic display parameter curve.
In one embodiment, the display parameter is a backlight brightness, the detection parameter is a light sensitivity value, the detection parameter sensor is a light sensor, and the automatic display parameter curve is an automatic backlight brightness curve.
In another embodiment, the display parameter is a backlight color temperature, the detection parameter is a color temperature value, the detection parameter sensor is a color temperature sensor, and the automatic display parameter curve is an automatic backlight color temperature curve.
It should be noted that, in the diagram at the upper left corner of fig. 2b, only three black dots are exemplarily drawn to illustrate the historical adjustment records, the number of the historical adjustment records theoretically only needs to be 1, may also be more than 3, may also be more than 20, and the like, and the embodiment of the present application is not limited.

The embodiment of the application can be used in a scene with repeatedly changed detection parameters, and can not output stable detection parameters under the condition that the detection parameters repeatedly change, so that the stability of the display parameters is ensured, and the problem of severe fluctuation of the display parameters under the condition that the detection parameters repeatedly change is avoided.

As shown in fig. 4, the method for adjusting the display parameters includes the following steps.

The mobile terminal judges that the quantity of the noise data in the noise sequence reaches a first threshold value, and can clear the noise sequence. The noise sequence is corresponding to the detection parameter sequence, and when the detection parameter sequence is cleared, the noise sequence is also cleared.
The first threshold may be preset and stored in a memory (e.g., a non-volatile memory) of the mobile terminal. The first threshold will typically be less than N, and may be set, for example, to equal N/2.
