For example, the second partition a in the display window corresponds to the first partition B on the display interface, and then the second partition a displays the display parameters of the first partition B. In addition, the local light control function is to equally divide the backlight area of the display interface of the smart television into a plurality of third partitions in advance, the third partitions are arranged in an array, and each third partition is controlled independently. Therefore, the partition information is partition information corresponding to the local light control function of the smart television (i.e., partition information corresponding to a plurality of third partitions), and is used for indicating the array row number and the array column number of the array formed by the third partitions, and according to the partition information, how many rows and how many columns the backlight area of the smart television is divided into can be determined.
The partition information includes partition row numbers and partition column numbers, wherein the partition row numbers indicate row numbers of an array formed by a plurality of third partitions, and the partition column numbers indicate column numbers of the array formed by the plurality of third partitions. For example, the number of the arrays formed by the third partitions is 64 × 36, the number of the partition rows is 64, and the number of the fractional columns is 36. In addition, the partition information may be obtained through a preset partition information call interface, and the number of partition rows and the number of partition columns are both configured with field names, for example, the field name corresponding to the partition function is row, and the field name corresponding to the partition column number is column. The partition information calling interface may be implemented in the following manner:
mTPicturePanel＝TPictureManager.getInstance(context).getPanel BlockNumAplArray()
int row＝mTPicturePanel.row；
int column＝mTPicturePanel.col；
Int[]blockNum＝mTPicturePanel.aplarray
the display parameter group comprises a display parameter group and a display parameter group, wherein the display parameter group comprises a display parameter group and a display parameter group, the display parameter group comprises mTPicturePoanel, the mTPicturePonel is used for calling a calling function of partition information, and the blockNum is the display parameter group corresponding to the moment when the intelligent television acquires the partition information, and the display parameter group comprises the moment when the partition information is acquired and display parameters required to be displayed by each third partition. The display parameter may be a display parameter of each pixel point in the third partition, and the display parameter of each pixel point is a parameter for reflecting a color corresponding to the pixel point, for example, the display parameter may be an RGB value of the pixel point, or may also be an hsl value of the pixel point, where the R value is a red channel value, the G value is a green channel value, and the B value is a blue channel value; the h value is the hue value, l is the brightness value, and s is the saturation value. In addition, it is worth to be explained that the third partition may include a plurality of pixel points, and when the third partition includes a plurality of pixel points, display parameters of any two pixel points of the plurality of pixel points are the same; and the display parameter of the third partition is the display parameter of any pixel point in the third partition.
Further, the partition borders are a plurality of transverse partition borders and a plurality of longitudinal partition borders which are drawn on the display interface of the smart television; any two transverse partition frames in the plurality of transverse partition frames are parallel, any two longitudinal partition frames in the plurality of longitudinal partition frames are parallel, and the plurality of transverse partition frames and the plurality of longitudinal partition frames are crossed transversely and longitudinally to divide the display interface into a plurality of first partitions; the plurality of first partitions correspond to the plurality of third partitions one to one, and the positions of the first partitions in the first array are the same as the positions of the reference partitions in the second array, wherein the first array is an array formed by the plurality of first partitions, the second array is an array formed by the plurality of third partitions, and the reference partitions are third partitions corresponding to the first partitions in the plurality of third partitions. For example, the position of the first partition in the first array is the second row and the third column, and then the position of the third partition corresponding to the first partition in the second array is also the second row and the third column.
In addition, it is worth to be noted that the trigger condition for acquiring the partition information of the smart television may be to start a local light control display function for the smart television, where the local light control display function is configured for the smart television and is used to display the display parameters of each third partition on a display interface of the smart television, where the local light control display function may be triggered by a trigger instruction input by a user, may also be triggered by receiving a start instruction generated by an external device, and may also be automatically triggered when the smart television is started. It can be understood that, in this embodiment, the partition frame is drawn on the display interface of the smart television when the local area light control display function is in the on state, so that a user can know the partition distribution position of the local area light control of the smart television based on the first partition formed by the partition frame. In addition, the display window in the subsequent step is drawn and displayed on the display interface of the smart television when the local area light control display function is in the starting state.
Further, in an implementation manner of this embodiment, the partition frame may be obtained by drawing through a pre-established drawing thread. Correspondingly, the obtaining of the partition information of the smart television and the drawing of the plurality of partition frames on the display interface of the smart television according to the partition information specifically include:
s11, creating a partition frame drawing thread, and acquiring partition information of the intelligent television through the partition drawing thread;
and S12, controlling the drawing thread to draw a plurality of partition frames on the display interface of the intelligent television according to the partition information.
Specifically, the partition frame drawing thread is a process in the smart television system, runs in the smart television system, and is used for drawing the partition frame on the smart television. Therefore, after the partition frame drawing thread is created, the partition information of the intelligent television can be acquired through the partition frame drawing thread, and the plurality of partition frames are drawn on the display interface of the intelligent television according to the partition information, so that the partition frames can be drawn independently. In addition, in this embodiment, the partition frame is displayed on the display interface of the smart television, the display interface of the smart television is divided into a plurality of first partitions, and the distribution positions of the third partitions can be known through the first partitions, so that a user can obtain light control areas for local light control. Meanwhile, in the process of local light control display, the distribution positions of the third partitions of the display interface of the smart television are not changed, so that the partition frames on the display interface are not changed. Therefore, the partition frame drawing thread only needs to draw the partition frame once, and consumption of the partition frame drawing thread on a memory and a CPU is reduced.
Further, the partition border drawing thread may call partition information through a preset partition information call interface, and draw the partition border by calling a drawing interface of the system (e.g., android native interface path. In addition, since a large number of temporary variables are generated by calling a drawing interface of the system, the embodiment reduces the temporary variables generated by drawing the partition frame in the local area control light display process by drawing the partition frame only once, so as to reduce the consumption of the local area control display on the memory. Meanwhile, the consumption of the local area control display on the memory is reduced, so that the memory recovery frequency can be reduced, and the consumption of a CPU (central processing unit) is reduced. In addition, in a specific implementation manner of this embodiment, the partition frame may adopt a dashed-line frame, which may not only ensure that the user obtains the third partition distribution position, but also avoid the influence of the partition frame on the display screen on the display interface.
Further, when the partition frame drawing thread is controlled to draw a plurality of partition frames on the display interface of the smart television according to the partition information, the resolution ratio of the smart television needs to be obtained, and the drawing position of each partition frame is determined according to the resolution ratio, wherein each partition frame comprises a plurality of transverse partition frames and a plurality of longitudinal partition frames, each transverse partition frame is used for equally dividing the display interface of the smart television into a plurality of lines, and the number of the plurality of lines is equal to the number of partition lines in the partition information. In addition, a straight line is drawn at each drawing position after the drawing position of each partition frame is determined, so that a plurality of transversely and longitudinally crossed straight lines are obtained, and the display interface of the intelligent television is divided into a plurality of first partitions through the transversely and longitudinally crossed straight lines.
For example, the following steps are carried out: the resolution of the smart television is 1024 × 720, and the partition information is 64 × 36, it may be determined that 64 horizontal partition borders and 36 vertical borders need to be drawn on the display interface. The left side line of the display interface is taken as a vertical frame as a starting frame, one vertical frame is drawn at intervals of 19 pixel points, and 36 vertical frames are drawn in sequence, wherein the starting frame is not drawn. Correspondingly, the side line on the upper side of the display interface is taken as a transverse partition frame as an initial frame, one transverse partition frame is drawn at intervals of 19 pixel points, and 36 longitudinal frames are drawn in sequence, wherein the initial frame is not required to be drawn.
And S20, acquiring a display parameter group of the smart television at preset intervals, and drawing a display window on the display interface according to the partition information and the display parameter group to display the local light control.
Specifically, the display window is a display window displayed on the display interface, and the display parameters corresponding to the first partitions of the display interface are displayed through the display window. Therefore, the display window comprises a plurality of second partitions, the second partitions correspond to the first partitions obtained by dividing the display interface through the partition frame in a one-to-one mode, each second partition in the second partitions displays the display parameters of the target partition, and the target partition is the first partition corresponding to the second partition in the first partitions. In addition, the first partitions and the backlight area are equally divided into third partitions in one-to-one correspondence.
In an implementation manner of this embodiment, the drawing a display window on the display interface according to the partition information and the display parameter group specifically includes:
a11, creating a display window, and dividing the display window into a plurality of second partitions according to the partition information, wherein the plurality of second partitions are in one-to-one correspondence with the plurality of first partitions, display parameters corresponding to each second partition in the plurality of second partitions are the same as those of a target partition, and the target partition is a first partition corresponding to the second partition in the plurality of first partitions;
and A12, determining display parameters corresponding to the second partitions according to the display parameter group, and drawing the display window on the display interface according to the display parameters corresponding to the second partitions respectively.
Specifically, the display window is used for being displayed at a preset position of a display interface, and the area of the display window is smaller than the display area of the display interface, so that the display window is prevented from blocking a display picture on the display interface. For example, the display window is displayed in a form of a hanging window at the lower right corner of the display interface, and the area of the display window is equal to one third of the display area (e.g., the display area of the display interface is 960 × 960, then the area of the display window is 320 × 320). Of course, in practical applications, in order to avoid the display window from affecting the display screen, the area of the display window may be one sixth of the display area.
Further, dividing the display window into a plurality of second partitions according to the partition information may be to divide the display window into a plurality of second partitions according to the number of partition lines and the number of partition columns included in the partition information, and each second partition in the plurality of second partitions corresponds to one first partition in the plurality of first partitions, so that the display parameters of the corresponding first partition are displayed through the second partition, so that a user can know the change of the display color of each first partition on the display interface through the display window, and the effect of area light control is intuitively obtained.
Further, the display parameter group is used for storing the display parameters corresponding to the first partitions, wherein the display parameter group is a one-dimensional array, a plurality of display parameters are stored in the display parameter group, each display parameter in the plurality of display parameters corresponds to one second partition, and the display parameter is the display parameter of the corresponding second partition. In this embodiment, the number of display parameters of the display parameter set is equal to the number of partitions of the second partition, wherein the number of fractions of the second partition is equal to the product of the number of partition rows and the number of partition columns. That is, the number of display parameters of the display parameter set is equal to the product of the number of partition rows and the number of partition columns. In addition, the display parameter group is one-dimensional data, and the second partitions in the display window are arranged in an array, so that after the display parameter group is obtained, the display parameter group needs to be converted into a two-bit array, and the two-bit array corresponds to the array formed by the second partitions in the display window one to one. Correspondingly, the determining the display parameters corresponding to the second partitions according to the display parameter array specifically includes:
equally dividing the display parameter array into a plurality of sub-display parameter arrays, wherein the number of display parameters included in the sub-display parameter arrays is equal to the number of the partition columns;
arranging the sub-color numerical values into a two-dimensional array according to a plurality of sub-color numerical values, wherein the number of rows of the two-dimensional array is the same as that of the partition rows, and the number of rows of each sub-display parameter array in the two-dimensional array corresponds to the position of each sub-display parameter array in the display parameter array;
and determining display parameters corresponding to the second partitions according to the two-dimensional array, wherein the positions of the second partitions in the display window correspond to the positions of the display parameters corresponding to the second partitions in the two-dimensional data.
Specifically, the equally dividing the display parameter array into a plurality of sub-display parameter arrays refers to dividing the display parameter array into a plurality of sub-display parameter sets, where the number of the plurality of sub-display parameter sets is equal to the number of partition rows, where any two digital display parameter sets in the plurality of sub-display parameter sets include equal number of first display parameters, and the number of the first display parameters is equal to the number of partition columns. In addition, after the sub display parameter groups are obtained through division, the sub display parameter groups are arranged in the column direction to form a two-dimensional array, each row in the two-dimensional array corresponds to one sub display parameter group, the sub display parameter groups corresponding to any two rows of the two-dimensional array are different, the row number of each row in the two-dimensional array is the same as the position of the sub display parameter group corresponding to the row in the display parameter group, each display parameter in the two-dimensional array corresponds to one second partition in the display window, and the display parameter is the display parameter corresponding to the second partition.
For example, the following steps are carried out: the display parameter set is { a1, a2, A3, a4, a5, A6}, the number of partition rows is 2, the number of partition columns is 3 (i.e. the second partition of the display window is 6, and 6 second partitions are arranged in a2 × 3 array), and then the display parameter set is divided into two sub-display parameter sets { [ a1, a2, A3], [ a4, a5, A6] }, which are respectively marked as a first sub-display parameter set and a second sub-display parameter set, and the number of display parameters in the first sub-display parameter set and the second sub-display parameter set is 3. After the first sub-display parameter group and the second sub-display parameter group are obtained through division, the first sub-display parameter group and the second sub-display parameter group are arranged according to the column direction, and a two-dimensional array is obtained as follows:
wherein the first row in the two-dimensional array corresponds to the first sub-set of display parameters, the second row in the two-dimensional array corresponds to the second sub-set of display parameters, and each display parameter corresponds to a second partition in the display window, e.g., a1 corresponds to the second partition in the upper left corner of the display window.
In an implementation manner of this embodiment, the obtaining a display parameter set of the smart television at every preset time interval, and drawing a display window on the display interface according to the partition information and the display parameter set to display the local-area-controlled light specifically includes:
s21, creating a display window drawing thread, and calling the display window drawing thread at intervals of preset time;
and S22, acquiring the display parameter group of the smart television through the display window drawing thread, and drawing a display window on the display interface according to the partition information and the display parameter group to display local light control.
Specifically, the display window drawing thread is used for drawing each second partition in the display window, where each second partition is drawn by using its corresponding display parameter. The display window drawing thread is created for the smart television and runs in the smart television system; the display parameter group of the smart television can be acquired through the display window drawing thread, and the display parameters corresponding to the second partitions are used for drawing the second partitions according to the display parameter group and the partition information, so that the display window can be drawn independently. In addition, in this embodiment, each second partition in the display window is used to display the display parameter of each first partition in the display screen on the display interface, and the display screen on the display interface is continuously updated, so that the display parameter of the first partition in the display screen is also continuously changed. Therefore, the display window drawing thread needs to acquire the display parameter group of the smart television at intervals of preset time, and redraws the display window according to the acquired display parameter group. It will be appreciated that the display window drawing thread needs to be invoked once every preset time interval, so that the display window is updated once every preset time interval. For example, the preset time is 200ms, the display window drawing thread draws the display window once every 200ms, that is, the drawing frequency of the display window drawing thread is 200 ms.
Further, the display window drawing thread may also call partition information and a display parameter group through a preset partition information call interface, and draw the display window through a color block drawing interface (for example, android native interface canvas. draw rec) of the call system, where each second partition in the display window is drawn one by one, and for each second partition, draw the second partition using the display parameter corresponding to the second partition.
