Along with the development of electronic equipment, the shape of display device also constantly changes, and the cutting curve of border has irregular curve usually among the current display device, and just comes fitting irregular curve effect through the curve of a section orthodrome and does not satisfy the demand, therefore how better cutting curve of laminating display screen to the optimization of the display effect that realizes at the display device edge is the problem that needs to solve.
In view of the foregoing problems, embodiments of the present application provide a display processing method, apparatus, and storage medium, which are used to optimize a display effect of an irregularly-shaped display device.
To facilitate understanding of the present embodiment, a detailed description is provided below of a display processing method, an apparatus, an electronic device, and a storage medium provided in the embodiments of the present application.
Please refer to fig. 1, which is a flowchart illustrating a display processing method according to an embodiment of the present disclosure. The display processing method provided by the embodiment of the application is applied to an electronic terminal, a display screen of the electronic terminal is provided with a fillet, and the method comprises the following steps:
s101, obtaining a fitting physical cutting curve of the display screen by utilizing a multi-section arc line fitting mode and a straight line fitting mode according to the physical cutting edge of the display screen of the electronic terminal.
The electronic terminal here can be an electronic product having a display screen, such as a mobile phone and a computer, and the display screen of the electronic terminal is in an irregular shape, as shown in fig. 2a to 2d, which are schematic diagrams of physical cutting edges of several display screens provided in an embodiment of the present application, wherein fig. 2a is a schematic diagram of a physical cutting edge of a rounded corner display screen, fig. 2b is a schematic diagram of a physical cutting edge of a rounded corner notch display screen, fig. 2c is a schematic diagram of a physical cutting edge of a rounded corner water drop display screen, and fig. 2d is a schematic diagram of a physical cutting edge of a rounded corner hole-digging display screen, wherein black is not a part of a hole-digging area of the display screen. It will be appreciated that the physical cut edges of the display screen are comprised of curved edges and straight edges, where the curved edges are generally irregularly curved.
For the straight line edges, each straight line edge can be fitted through a straight line fitting mode to obtain at least one line segment. For the curve edge, if come the fitting through a section of positive circular arc, the image that the screen display was shown at last through processing probably has blank part, consequently, through multistage arc fitting mode, to every curve edge, fit this curve edge through multistage arc fitting mode to obtain multistage fitting arc, connect the multistage fitting arc and at least one line segment that will fit and obtain in order, splice into the complete fitting physics cutting curve of display screen.
And S102, acquiring an image to be displayed.
The image to be displayed can be any image, so that the image to be displayed is displayed through the display screen, and the image to be displayed fills the whole display screen.
S103, determining a display optimization coefficient matrix corresponding to the image to be displayed according to the fitted physical cutting curve, wherein each element in the display optimization coefficient matrix is the display optimization coefficient of a corresponding pixel unit in the image to be displayed.
The display optimization coefficient here refers to a relationship between all pixels of an image to be displayed and pixels displayed on pixel units of a display screen when the image to be displayed is displayed on the display screen. For each pixel cell in the image to be displayed, the following processing is performed: determining whether the fitted physical cutting curve crosses the pixel unit, and if the fitted physical cutting curve does not cross the pixel unit, determining whether the pixel unit is positioned in the closed area formed by the fitted physical cutting curve; if the pixel unit is located in the closed area, the display optimization coefficient corresponding to the pixel unit is 1; if the pixel unit is positioned outside the closed area, the display optimization coefficient corresponding to the pixel unit is 0; and if the fitted physical cutting curve crosses the pixel unit, determining the effective display area of the pixel unit, and determining the display optimization coefficient corresponding to the pixel unit according to the ratio of the effective display area of the pixel unit to the standard display area.
As shown in fig. 3, a schematic diagram of a partial image of an image to be displayed cut by fitting a physical cutting curve. It will be appreciated that within the 9 x 9 sized region shown in figure 3, each grid represents a pixel in the image to be displayed. In the display process, if the original size of the image to be displayed exceeds the display range of the display screen, part of pixels of the image to be displayed are not displayed or part of pixels are displayed. The following three situations exist for all pixels of a specific image to be displayed:
the first case is that the pixels are completely outside the screen and cannot be displayed by the screen, that is, the whole pixels outside the physical cutting curve area are fitted, and at this time, the display optimization coefficient of the pixel unit corresponding to the pixels is 0, which means that there is no pixel unit for displaying the pixels.
The second case is that the pixels are completely located in the screen and are displayed completely by the screen, that is, the complete pixels in the area of the fitted physical cutting curve are displayed completely, at this time, the display optimization coefficient of the pixel unit corresponding to the pixels of this kind is 1, and at this time, the pixel unit representing this part does not need to be optimized by edge processing.
The third situation is that the pixel part is positioned in the screen and is displayed by the screen part, namely, the incomplete pixels in the physical cutting curve area are fitted, and at the moment, the display optimization coefficient of the incomplete pixels is calculated according to the proportion of the effective display area of the incomplete pixels in the physical cutting curve area to the standard area of the pixels. The standard area of a pixel here refers to the area of a complete pixel, and the size of each pixel is the same.
Specifically, the effective display area of each pixel unit is determined by: determining an area calculation mode of the pixel unit based on the position relation between the fitted physical cutting curve and the pixel unit; and calculating the display area of the pixel unit in the closed area in a determined area calculation mode, and determining the calculated display area as the effective display area of the pixel unit.
It is understood that the approximate area of the incomplete pixel is calculated in an approximate manner, such as the incomplete pixel marked with 1 in fig. 3, which can be approximated as the area of the triangle at the bottom right corner. As in the incomplete pixel labeled 2 in fig. 3, it can be calculated as approximately the area of the lower trapezoid. As in the incomplete pixel labeled 3 in fig. 3, it can be calculated by approximating it to the right half trapezoidal area. As shown in fig. 3, the incomplete pixel labeled with 4 may be obtained by first calculating the approximate area of the triangle at the top left corner, and then subtracting the approximate area of the triangle at the top left corner from the standard area.
And S104, filtering each element in the display optimization coefficient matrix through a target filter to obtain a filtering display coefficient corresponding to each pixel unit in the image to be displayed.
Here, the target filter corresponding to each sub-pixel in each pixel unit needs to be determined according to the arrangement structure of each sub-pixel in each pixel unit of the display screen, so as to adapt to different types of display screens. Fig. 4 is a schematic diagram of a target filter according to an embodiment of the present disclosure. The target filter here may be 3 × 3 or 9 × 9, etc., but the sum of all the coefficients in the target filter is 256.
Specifically, for example, if the first pixel unit includes two sub-pixels of R and G, a first target filter corresponding to the R pixel and a second target filter corresponding to the G pixel need to be determined. The second pixel unit includes two sub-pixels, i.e., G and B, and a third target filter corresponding to the G pixel and a fourth target filter corresponding to the B pixel need to be determined. The second target filter and the third target filter may be the same or different. The first pixel unit and the second pixel unit are two pixel units which are different at will on the display screen.
And filtering the display optimization coefficients of the pixel units in the optimization coefficient matrix through a target filter to obtain the filtering display coefficients corresponding to the pixel units. Illustratively, for a first pixel unit, filtering is performed on an R pixel through a first target filter to obtain a filtering display coefficient corresponding to the R pixel, filtering is performed on a G pixel through a second target filter to obtain a filtering display coefficient corresponding to the G pixel, and the filtering display coefficient corresponding to the R pixel and the filtering display coefficient corresponding to the G pixel together form a filtering display coefficient corresponding to the first pixel unit.
And S105, aiming at each pixel unit in the image to be displayed, obtaining target display data corresponding to the pixel unit according to the original display data corresponding to the pixel unit and the filtering display coefficient.
The original display data refers to original pixel values of an image to be displayed in the pixel unit, wherein the original display data comprises three components of RGB.
Specifically, for one pixel unit, the original display data corresponding to the pixel unit is multiplied by the filtering display coefficient to obtain a corresponding target adjustment coefficient. Since the range of the original display data is 0 to 255 and the range of the filtered display coefficient is 0 to 255, the target adjustment coefficient needs to be quantized and converted into the target display data, so as to ensure that the range of the target display data is 0 to 255. Illustratively, the quantization process may divide the target coefficient by 256 to obtain target display data.
And S106, transmitting the target display data corresponding to each pixel unit to the pixel unit so as to present the image to be displayed on the display screen.
Specifically, for each pixel unit, the output of each sub-pixel is controlled according to the target display data corresponding to all sub-pixels included in the pixel unit, so that the image to be displayed is presented on the display screen.
The display processing method provided by the embodiment of the application obtains a fitted physical cutting curve of a display screen by referring to a physical cutting edge of the display screen of an electronic terminal and utilizing a multi-section arc fitting mode and a straight line fitting mode, determines a display optimization coefficient matrix corresponding to an image to be displayed according to the fitted physical cutting curve, wherein each element in the display optimization coefficient matrix is a display optimization coefficient of a corresponding pixel unit in the image to be displayed, filters each element in the display optimization coefficient matrix through a target filter to obtain a filtering display coefficient corresponding to each pixel unit in the image to be displayed, obtains target display data corresponding to each pixel unit according to original display data and the filtering display coefficient corresponding to the pixel unit for each pixel unit in the image to be displayed, and transmits the target display data corresponding to the pixel unit for each pixel unit, the image to be displayed is presented on the display screen, so that the optimized display effect of the display screen on the image to be displayed is realized.
Fig. 5 is a flowchart of the steps provided in the embodiments of the present application for determining a fitted arc. In an alternative example, in step S101, any one of the multiple fitting arcs corresponding to each curve edge may be obtained by:
s501, determining the target position in the edge of the curve as the starting point of the preset conical curve.
Fig. 6 is a schematic diagram of curved edges on a display screen according to an embodiment of the present application, where each curved frame is a curved edge. It is understood that the physical cutting edge of a display screen includes two parts, namely a curved edge and a straight edge, and the curved edge may include a plurality of curved edges, and one of the curved edges is determined as a target curved edge and represents a curved edge to be currently fitted.
The target position refers to a starting point or an ending point of the curve edge, and the starting point of the preset conical curve is any point on the preset conical curve. Here, a coordinate system may be established with the plane of the display screen, and the positions of the start point and the end point of the edge of the target curve in the coordinate system may be determined based on the coordinates of the adjacent edges of the edge of the target curve. First, a circular curve can be selected as a preset conical curve, and the position of the preset conical curve is determined. Since it is necessary to fit the edge of the target curve by the preset conic section, a point on the preset conic section is the same as the position of the starting point of the edge of the target curve, and the edge of the target curve is fitted by an arc line starting from the point on the preset conic section.
S502, determining the fitting degree of the preset conic curve and the curve edge line by line in the direction of the ending position of the curve edge by taking the line of the starting point as the starting line of the intercepting frame.
The intercepting box is used for intercepting the preset conical curve so as to obtain the current fitting arc line. Specifically, the fitting degree of the current preset conic curve and the edge of the target curve is determined downwards line by line from the action starting line where the starting point of the edge of the target curve is located.
S503, if the fitting degree of the preset conical curve and the curve edge does not meet the preset fitting condition, adjusting the axial length of the preset conical curve, and continuously determining the fitting degree of the adjusted preset conical curve and the curve edge.
Specifically, if the edge of the current circular preset conical curve is completely not attached to the edge of the target curve or the attached part is small, the axial length of the preset conical curve is adjusted, the preset conical curve is adjusted to be elliptical until the length of the attached part of the preset conical curve and the edge of the target curve exceeds a preset value, and then the preset fitting condition is determined to be met. The preset value can be set by splicing several fitting arcs according to the edge of a curve. In general, a curve edge is spliced by three or five fitting arcs to achieve the best splicing effect, so that the preset value can be one third or one fifth of the total length of the target curve edge, and the like.
S504, if the fitting degree of the preset conic curve and the curve edge meets the preset fitting condition, determining the ending line of the intercepting frame.
And S505, determining the line segment of the preset conic curve intercepted between the starting line and the ending line of the intercepting frame as any fitting arc line.
And when the current preset conic curve meets the preset fitting condition, taking the line at the tail end of the edge joint of the preset conic curve and the target curve as the finishing line of the intercepting frame, wherein the intercepted preset conic curve segment in the intercepting frame is the current fitting arc segment.
As shown in fig. 7, an exemplary diagram of a fitted physical cutting curve is provided in the embodiments of the present application. For the target curve edge, illustratively, fitting is performed by splicing five fitting arcs, wherein the dashed rectangle is a truncated box corresponding to each fitting arc. The coordinate system shown in fig. 7 has the abscissa col and the ordinate row. Therefore, the position of the current fitting physical cutting curve can be obtained and used for determining the cutting relation of the fitting physical cutting curve to the pixels in the image to be displayed.
And after the first section of fitting arc line is determined, taking the end point of the first section of arc line as the initial point of the next section of fitting arc line, repeating the steps from S501 to S505, thus obtaining a second section of fitting arc line, a third section of fitting arc line, a fourth section of fitting arc line and a fifth section of fitting arc line in sequence, splicing the first section of fitting arc line, the second section of fitting arc line, the third section of fitting arc line, the fourth section of fitting arc line and the fifth section of fitting arc line in sequence, and finally obtaining a fitting physical cutting curve corresponding to the edge of the target curve. The obtained physical cutting curve can be closer to the physical cutting edge of the display screen, so that the better display effect of the image to be displayed is further ensured.
