Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
It should be noted that, the user information (including but not limited to user equipment information, user personal information, etc.) and the data (including but not limited to data for presentation, analyzed data, etc.) related to the present application are both information and data authorized by the user or sufficiently authorized by each party; correspondingly, the application also provides a corresponding user authorization entry for the user to select authorization or select rejection.
In one embodiment, as shown in fig. 1, an image display method is provided, and this embodiment is applied to a terminal for illustration by the method. In this embodiment, the method includes the steps of:
step 101, obtaining target display parameters of edge pixels of each screen; the target display parameters are determined according to the division result of the screen edge fitting curve on the corresponding areas of the screen edge pixels; the screen edge fitting curve is a second-order curve obtained by fitting the screen edge;
the screen edge pixels may be located in a border area of the screen edge, and the border area of the screen edge may be obtained based on a screen arc border of a screen clipping (e.g. cutting a round corner, digging a hole, and cutting a position, as shown in fig. 2, where 1 is a round corner, 2 is a hole, and 3 is a cut in fig. 2), for example, the screen edge of the mobile phone display screen may have a plurality of screen edge pixels.
As an example, the screen edge may be fitted in advance to construct a second order curve for the screen edge, and as the screen edge fitting curve, for example, the screen edge may be fitted by a second order curve equation such as a B-spline curve, a circle, or an ellipse, to obtain the screen edge fitting curve.
In practical application, a screen edge fitting curve obtained by fitting the screen edge can be adopted, and the target display parameters, such as anti-aliasing coefficients, of the screen edge pixels can be determined according to the division result of the screen edge fitting curve on the corresponding areas of the screen edge pixels by sampling the screen edge fitting curve.
Specifically, a screen edge fitting curve for the screen edge fitting may be pre-constructed, and the pre-stored anti-aliasing coefficients (i.e., target display parameters) of each screen edge pixel may be obtained by sampling the screen edge fitting curve, calculating the anti-aliasing coefficients of each screen edge pixel based on the division result of the screen edge fitting curve for the corresponding region of each screen edge pixel, and sequentially storing the anti-aliasing coefficients into hardware, e.g., by pre-generating the screen edge fitting curve and calculating the anti-aliasing coefficients of each screen edge pixel.
In an example, compared with a conventional method in which an edge arc edge is formed by combining a plurality of first-order folding lines, the problem of low anti-aliasing edge smoothness exists at a position with a large slope change, and the technical scheme of the embodiment is to fit a screen edge through a second-order curve equation such as a B-spline curve, a circle or an ellipse, and the like, so that a screen edge fitting curve is constructed.
Step 102, for each of the screen edge pixels, adjusting a pixel value corresponding to each sub-pixel in the screen edge pixel according to the target display parameter and an arrangement condition between the sub-pixel and an adjacent sub-pixel of the screen edge pixel; the adjacent sub-pixels are sub-pixels in peripheral pixels in a preset range corresponding to the screen edge pixels, and the adjacent sub-pixels and the sub-pixels of the screen edge pixels have the same channel type;
the sub-pixels of the edge-of-screen pixel may correspond to different channel types, and may include an R channel corresponding to a red sub-pixel, a G channel corresponding to a green sub-pixel, and a B channel corresponding to a blue sub-pixel; different arrangement conditions of the sub-pixels can exist in the peripheral pixels corresponding to the edge pixels of the screen, for example, the arrangement positions and/or the arrangement distances between the sub-pixels and the adjacent sub-pixels are different.
In a specific implementation, for each screen edge pixel, according to the target display parameter of the screen edge pixel and the arrangement condition between the sub-pixels of the screen edge pixel and the adjacent sub-pixels, the pixel value corresponding to each sub-pixel in the screen edge pixel is adjusted, so that the anti-aliasing effect can be further improved by considering the influence of arrangement of different sub-pixels.
For example, after the anti-aliasing coefficient of each screen edge pixel is obtained through the hardware storage space, the target display parameter of each screen edge pixel is obtained, the anti-aliasing coefficient of the pixel point can be distributed to the adjacent sub-pixels based on convolution operation of the sub-pixel scale, and then a transition zone can be formed under the sub-pixel scale, so that the anti-aliasing effect is further improved.
In an example, when the edge of the screen is a non-horizontal, non-vertical straight line or polygonal boundary, such as cutting a rounded corner, hole digging, notch and the like, when the screen is cut, the edge of the screen can have a saw-tooth appearance, so that the display of image information is distorted, namely, the aliasing effect is caused, and in order to reduce or eliminate the aliasing effect, anti-aliasing processing is required to be performed, so that the anti-aliasing effect is realized; and drawing a second-order curve by fitting the edges of the screen, sampling the second-order curve to calculate an anti-aliasing coefficient of each screen edge pixel, and further distributing the anti-aliasing coefficient to the adjacent sub-pixels by utilizing convolution of the sub-pixel scale, thereby realizing the anti-aliasing effect.
Step 103, determining a target pixel value of the screen edge pixel based on the pixel value corresponding to each sub-pixel in the screen edge pixel.
In practical application, when image data is acquired for screen display, for each screen edge pixel, a target pixel value is displayed based on a pixel value corresponding to each sub-pixel in the screen edge pixel, so that the jaggy feeling of an image represented by the screen edge pixel can be weakened, and an anti-aliasing effect is realized.
In an example, an AMOLED (Active-matrix organic light-emitting diode) screen has the characteristic of Active luminescence, the display of mobile phone screen pixels can be independently controlled through a single pixel, when anti-aliasing processing is performed on the AMOLED screen, a second order curve (namely a screen edge fitting curve) is drawn through fitting the screen edge, the second order curve is sampled, anti-aliasing coefficients of all the screen edge pixels are obtained through calculation, the smooth effect of the anti-aliasing curves is ensured, further, the anti-aliasing coefficients can be distributed to nearby sub-pixels through convolution of sub-pixel dimensions, the problem that the coefficients are calculated and distributed in units of pixels in the traditional method, the arrangement of the sub-pixels is not considered is solved, and the anti-aliasing effect is improved by combining and considering the influence of different sub-pixel arrangements.
According to the image display method, the target display parameters of the edge pixels of the screen are obtained, then, for each edge pixel of the screen, the pixel values corresponding to the sub-pixels in the edge pixels of the screen are adjusted according to the target display parameters and the arrangement conditions between the sub-pixels and the adjacent sub-pixels of the edge pixels of the screen, and then, the target pixel values of the edge pixels of the screen are determined based on the pixel values corresponding to the sub-pixels in the edge pixels of the screen, so that the anti-aliasing processing optimization of the edge pixels of the screen is realized, the target display parameters of the edge pixels of the screen are determined based on a second-order curve obtained by fitting the edge of the screen, and then, the pixel values corresponding to the sub-pixels are adjusted according to the arrangement conditions between the adjacent sub-pixels, so that the target pixel values of the edge pixels of the screen are obtained, the jaggy feeling at the edge of the screen is eliminated, the display effect of the screen is improved, the arrangement of the sub-pixels is considered, and the anti-aliasing effect is improved.
In one embodiment, before the step of acquiring the target display parameter of each screen edge pixel, the steps of:
fitting is carried out based on the edge shape of the screen edge, and a second-order curve corresponding to the screen edge is constructed and used as the screen edge fitting curve.
In practical application, the edge shape of the screen edge is fitted through a B-spline curve, a circle or an elliptic curve to obtain a screen edge fitting curve, and continuity of first-order leads of each part of the curve can be ensured based on the property of a second-order curve equation, so that the anti-aliasing curve is smoother.
For example, the parameters of the B-spline curve may include n+1 control points, a node vector of m+1 nodes, and the number of times p, where n, m, p need to satisfy a preset condition, such as m=n+p+1, and since it is determined as a second-order curve, the numbers of the control points and nodes of the B-spline curve may be n+1 and n+4, respectively, and the second-order B-spline curve controlled by the control points and nodes may be represented as follows:
wherein N is i,2 (u) is a quadratic B-spline basis function; the nodes are uniformly distributed, and the repeatability of the first node and the last node is 3 so as to ensure that the curve is tangent to the first side and the last side of the control fold line; a second order curve approximating the edge shape of the screen edge can be obtained by changing the positions of the n+1 control points.
In this embodiment, by fitting based on the edge shape of the screen edge, a second order curve corresponding to the screen edge is constructed, and the second order curve can be drawn by fitting the screen edge as the screen edge fitting curve, so that data support is provided for further sampling the second order curve, and the anti-aliasing curve can be smoother.
In one embodiment, after the step of fitting based on the edge shape of the screen edge to construct a second-order curve corresponding to the screen edge as the screen edge fitting curve, the method may include the following steps:
sampling the screen edge fitting curve according to the sampling interval information, and obtaining a plurality of sampling points and sampling point coordinates thereof in each screen edge pixel based on the dividing result of the screen edge fitting curve on the corresponding area of each screen edge pixel;
as an example, sample interval information may be preset, which may be used to equally sample the screen edge fit curve.
In a specific implementation, by constructing a screen edge fitting curve, the screen edge fitting curve can be sampled at equal intervals according to sampling interval information, and then a plurality of sampling points and coordinates of the sampling points in each screen edge pixel can be obtained based on a division result of the screen edge fitting curve on a corresponding area of each screen edge pixel, for example, the coordinates corresponding to each sampling point can be obtained according to the condition that the sampling points fall in the screen edge pixel.
And aiming at each screen edge pixel, obtaining target display parameters of the screen edge pixel according to the plurality of sampling points and the sampling point coordinates thereof, the sampling interval information and the pixel display azimuth of the screen edge pixel.
Wherein the pixel display orientation may be used to characterize the orientation of the screen edge pixels to the screen display area, such as from the pixel display orientation of the screen edge pixels a, the orientation of the screen display area or the screen non-display area relative to the screen edge pixels a may be determined.
After the sampling point coordinates are obtained, for each screen edge pixel, according to a plurality of sampling points and the sampling point coordinates thereof, sampling interval information and pixel display orientations of the screen edge pixels, target display parameters of the screen edge pixels are obtained, for example, the occupied area of each sampling point can be calculated and summed according to the positions of each sampling point in the screen edge pixels, the sampling point intervals and the directions of the screen edges, and the anti-aliasing coefficients of the screen edge pixels, namely the target display parameters, are obtained.
In an example, as shown in fig. 3a, the pixel point on the right side of the figure faces upward (i.e. the pixel display orientation of the pixel on the screen edge), the screen edge fitting curve may be sampled at equal intervals by presetting the sampling interval information, for example, the sampling interval is 1/m, where n+1 sampling points (i.e. multiple sampling points) fall in the pixel point, and the coordinates of each sampling point may be (x 0 ，y 0 )，…(x i ，y i )，…(x n ，y n ) The gray area in the pixel point is the area to be calculated, the anti-aliasing coefficient can be obtained by accumulating the areas corresponding to the sampling points in the pixel point, for example, the area of the screen edge pixel can be divided by the unit pixel area by the accumulated screen edge fitting curve to obtain the anti-aliasing coefficient, when the unit pixel area is 1, the accumulated area value is the anti-aliasing coefficient, and the calculated anti-aliasing coefficient can be stored in the hardware storage space according to the sequence of the screen edge pixel.
For example, the antialiasing coefficient may be obtained in such a manner that when the unit pixel area is 1, a is the antialiasing coefficient:
wherein A is the area of the screen edge fitting curve drawn across the screen edge pixels, when the unit pixel area is 1, A is the antialiasing coefficient, the screen edge pixels have corresponding coordinates of (X, Y) - (X+1, Y), i is one of the n+1 sampling points in the screen edge pixels, and the sampling interval is 1/m.
In this embodiment, a plurality of sampling points and sampling point coordinates thereof in each screen edge pixel are obtained by sampling a screen edge fitting curve according to sampling interval information, and based on a division result of the screen edge fitting curve in a region corresponding to each screen edge pixel, so that for each screen edge pixel, a target display parameter of the screen edge pixel is obtained according to the plurality of sampling points and the sampling point coordinates thereof, the sampling interval information, and a pixel display azimuth of the screen edge pixel, and an anti-aliasing coefficient of the pixel can be obtained by sampling a second-order curve according to a condition that the sampling points fall on the pixel, thereby providing data support for a convolution operation of a subsequent sub-pixel scale.
In one embodiment, the obtaining the plurality of sampling points and the coordinates of the sampling points thereof in each of the screen edge pixels may include the following steps:
determining a plurality of sampling points and sampling point coordinates thereof in each screen edge pixel according to pixel position coordinates corresponding to each screen edge pixel and the sampling interval information;
in an example, the plurality of sampling points and the coordinates of the sampling points thereof in each screen edge pixel can be determined according to the coordinates of the pixel positions corresponding to each screen edge pixel, such as coordinates (X, Y) - (x+1, Y) corresponding to the pixel points in fig. 3a, and the sampling interval information, such as sampling interval of 1/m, such as n+1 sampling points and the coordinates (X) of the sampling points thereof in the pixel points on the right side of fig. 3a 0 ，y 0 )，…(x i ，y i )，…(x n ，y n )。
For each screen edge pixel, obtaining a target display parameter of the screen edge pixel according to the plurality of sampling points and the sampling point coordinates thereof, the sampling interval information and the pixel display azimuth of the screen edge pixel, including:
obtaining a sampling area corresponding to each sampling point in the screen edge pixel according to the coordinates of the sampling points, the sampling interval information and the pixel display azimuth of the screen edge pixel; and accumulating the sampling areas corresponding to the sampling points to obtain target dividing areas of the screen edge pixels, and taking the ratio of the areas of the target dividing areas to the areas of the unit pixels as the target display parameters.
In practical application, as shown in fig. 3a, for each sampling point in the pixel points on the right side of the figure, the coordinates of each sampling point, such as (x 0 ，y 0 )，…(x i ，y i )，…(x n ，y n ) The sampling interval information, such as the sampling interval of 1/m, and the pixel display azimuth of the pixel point, such as the edge of the pixel point facing upwards, calculate the sampling area corresponding to the sampling point, such as the area corresponding to the sampling point in the gray area, and further, by accumulating the areas corresponding to the sampling points in the pixel point, the area of the gray area (i.e. the target dividing area) in the pixel point can be obtained, and further, the ratio of the obtained sampling area to the unit pixel area, i.e. the anti-aliasing coefficient, can be used as the target display parameter.
For example, when the unit pixel area is 1, the area corresponding to the target division area may be an antialiasing coefficient, that is, a target display parameter.
In this embodiment, a plurality of sampling points and sampling point coordinates thereof in each screen edge pixel are determined according to pixel position coordinates and sampling interval information corresponding to each screen edge pixel, then, for each sampling point in the screen edge pixel, according to the sampling point coordinates, the sampling interval information and the pixel display orientation of the screen edge pixel, a sampling area corresponding to the sampling point is obtained, and further, accumulation processing is performed on the sampling areas corresponding to the plurality of sampling points, so as to obtain a target division area of the screen edge pixel, and a ratio of an area of the target division area to an area of a unit pixel is used as a target display parameter.
In one embodiment, for each of the screen edge pixels, according to the target display parameter and the arrangement between the sub-pixels of the screen edge pixel and the adjacent sub-pixels, the adjusting the pixel value corresponding to each sub-pixel in the screen edge pixel may include the following steps:
for each screen edge pixel, acquiring an initial gray value of a preset range corresponding to the screen edge pixel; a plurality of peripheral pixels are arranged in the preset range;
in practical application, for each screen edge pixel, a preset range, such as a sub-pixel convolution range, corresponding to the screen edge pixel may be determined, and then, based on a plurality of peripheral pixels included in the preset range, a gray value displayed in the range, that is, an initial gray value, may be obtained.
And adjusting pixel values corresponding to all sub-pixels in the screen edge pixels according to the target display parameters and arrangement conditions between the sub-pixels and adjacent sub-pixels of the screen edge pixels based on the initial gray values.
In an example, based on the displayed gray values (i.e., initial gray values) corresponding to the plurality of peripheral pixels in the preset range, the anti-aliasing coefficients (i.e., target display parameters) of the edge pixels of the screen are allocated to the adjacent sub-pixels according to the arrangement condition, such as the arrangement position and the arrangement distance, between the sub-pixels of the edge pixels of the screen and the adjacent sub-pixels through the convolution operation of the sub-pixel scale, so as to adjust the pixel values corresponding to the sub-pixels in the edge pixels of the screen, such as obtaining the final output values of the red sub-pixel, the green sub-pixel and the blue sub-pixel.
In this embodiment, by acquiring, for each screen edge pixel, an initial gray value of a preset range corresponding to the screen edge pixel, and further adjusting, based on the initial gray value, a pixel value corresponding to each sub-pixel in the screen edge pixel according to a target display parameter and an arrangement condition between the sub-pixel and an adjacent sub-pixel of the screen edge pixel, by considering an influence of arrangement of different sub-pixels, an anti-aliasing effect can be further improved.
In one embodiment, the adjusting, based on the initial gray value, the pixel value corresponding to each sub-pixel in the edge pixel of the screen according to the target display parameter and the arrangement between the sub-pixel and the adjacent sub-pixel of the edge pixel of the screen may include the following steps:
acquiring a weight coefficient set corresponding to each sub-pixel in the screen edge pixel; the weight coefficient set is obtained based on the arrangement positions and arrangement distances of the sub-pixels of the screen edge pixels and adjacent sub-pixels and the channel type, and each adjacent sub-pixel has a corresponding weight coefficient based on the channel type, the arrangement positions and the arrangement distances; and aiming at the sub-pixels of each channel type, determining the gray value corresponding to the sub-pixel by combining the weight coefficient set corresponding to the sub-pixel, the target display parameter and the initial gray value so as to adjust the pixel value corresponding to each sub-pixel in the screen edge pixel.
In an example, as shown in fig. 3b, weights may be set for each sub-pixel separately according to different sub-pixel arrangements. Because the arrangement and the area of the sub-pixels are different, the distance between the sub-pixels in the odd and even columns and the output sub-pixels (i.e. the sub-pixels adjacent to the sub-pixels and the edge pixels of the screen) is different, different weights can be set for the sub-pixels of different channel types in the odd and even columns.
For example, for the final output value of the red sub-pixel, the final output value of the red sub-pixel needs to be obtained by multiplying the gray value of the red sub-pixel in the m×n range (i.e. the preset range), multiplying the antialiasing coefficient of the pixel point, and multiplying the convolution weight (i.e. the weight coefficient set corresponding to each sub-pixel) for accumulation, which can be calculated as follows:
where m and n represent the range of the sub-pixel convolution (i.e., a preset range), if the convolution range is 3x3, then m=3, n=3; g (x+i, y+j) characterizes the gray values displayed in the m×n range (i.e., the initial gray values); w (W) ood\even (i, j) representing weights corresponding to the sub-pixels of different channel types in odd and even columns; g (x, y) characterizes the gray value (i.e., the target pixel value of the screen edge pixel) that is ultimately output at (x, y).
In yet another example, the gray values displayed in the range of 4x3 in fig. 3b may be represented as follows:
| (R 00 ，G 00 ，B 00 ) | (R 01 ，G 01 ，B 01 ) | (R 02 ，G 02 ，B 02 ) | (R 03 ，G 03 ，B 03 ) |
| (R 10 ，G 10 ，B 10 ) | (R 11 ，G 11 ，B 11 ) | (R 12 ，G 12 ，B 12 ) | (R 13 ，G 13 ，B 13 ) |
| (R 20 ，G 20 ，B 20 ) | (R 21 ，G 21 ，B 21 ) | (R 22 ，G 22 ，B 22 ) | (R 23 ，G 23 ，B 23 ) |
The output gray value of the subpixel R at (1, 1) can be calculated as follows:
R(1，1)＝R 00 *A 00 *W Rodd00 +R 01 *A 01 *W Rodd01 +R 02 *A 02 *W Rodd02 +R 10 *A 10 *W Rodd10 +R 11 *A 11 *W Rodd11 +R 12 *A 12 *W Rodd12 +R 20 *A 20 *W Rodd20 +R 21 *A 21 *W Rodd21 +R 22 *A 22 *W Rodd22
the output gray value of the sub-pixel G at (1, 1) can be calculated as follows:
G(2，1)＝G 01 *A 01 *W Geven00 +G 02 *A 02 *W Geven01 +G 03 *A 03 *W Geven02 +G 11 *A 11 *W Geven10 +G 12 *A 12 *W Geven11 +G 13 *A 13 *W Geven12 +G 21 *A 21 *W Geven20 +G 22 *A 22 *W Geven21 +G 23 *A 23 *W Geven22
in this embodiment, by acquiring the set of weight coefficients corresponding to each sub-pixel in the edge pixel of the screen, and further combining the set of weight coefficients corresponding to each sub-pixel, the target display parameter, and the initial gray value for each sub-pixel of the channel type, determining the gray value corresponding to the sub-pixel, so as to adjust the pixel value corresponding to each sub-pixel in the edge pixel of the screen, a transition zone can be formed at the sub-pixel scale based on convolution operation of the sub-pixel scale, and thus the anti-aliasing effect can be improved.
In one embodiment, the determining the target pixel value of the screen edge pixel based on the pixel value corresponding to each sub-pixel in the screen edge pixel may include the following steps:
and fusing pixel values corresponding to all sub-pixels in the screen edge pixels to obtain fused pixel values which are used as target pixel values of the screen edge pixels so as to weaken the jaggy feeling of the image represented by the screen edge pixels and present a transition zone effect based on the sub-pixel scale.
In practical application, the pixel values corresponding to all the sub-pixels in the screen edge pixels can be fused to obtain fused pixel values, such as final output gray values at the corresponding coordinates of the screen edge pixels, so that the target pixel values of the screen edge pixels can be determined, the jaggy feeling of the image represented by the screen edge pixels is weakened, and the transition zone effect is represented based on the sub-pixel scale.
In this embodiment, the pixel values corresponding to the sub-pixels in the edge pixels of the screen are fused to obtain the fused pixel value, which is used as the target pixel value of the edge pixels of the screen, so as to weaken the jaggy feel of the image represented by the edge pixels of the screen, and the transition zone effect is represented based on the sub-pixel scale, thereby improving the display efficiency.

In step 404, the sampling areas corresponding to the plurality of sampling points are accumulated to obtain a target divided area of the screen edge pixels, and the ratio of the area of the target divided area to the area of the unit pixel is used as the target display parameter. In step 405, target display parameters for each screen edge pixel are obtained. In step 406, for each screen edge pixel, an initial gray value of a preset range corresponding to the screen edge pixel is obtained; the preset range is provided with a plurality of peripheral pixels. In step 407, a set of weight coefficients corresponding to each sub-pixel in the edge pixels of the screen is obtained; the weight coefficient set is obtained based on the arrangement positions and arrangement distances of the sub-pixels of the screen edge pixels and the adjacent sub-pixels and the channel type. In step 408, for each sub-pixel of the channel type, the gray value corresponding to the sub-pixel is determined by combining the set of weight coefficients corresponding to the sub-pixel, the target display parameter, and the initial gray value, so as to adjust the pixel value corresponding to each sub-pixel in the edge pixel of the screen.
