Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Referring to fig. 1, fig. 1 is a block diagram of a display device according to an embodiment of the present disclosure, where the display device 100 includes: at least one processor 101, at least one communication interface 102, at least one memory 103, and at least one communication bus 104. Wherein, the communication bus 104 is used for implementing direct connection communication of these components, the communication interface 102 is used for communicating signaling or data with other node devices, and the memory 103 stores machine-readable instructions executable by the processor 101. When the display device 100 operates, the processor 101 communicates with the memory 103 through the communication bus 104, and the machine readable instructions are called by the processor 101 to execute the image data processing method provided by the embodiment of the application.

The processor 101 may be an integrated circuit chip having signal processing capabilities. The Processor 101 may be a general-purpose Processor, and includes a Central Processing Unit (CPU), a Network Processor (NP), and the like; but also a Digital Signal Processor (DSP), an application specific integrated circuit (ASAC), an off-the-shelf Programmable Gate Array (FPGA) or other Programmable logic device, discrete Gate or transistor logic device, discrete hardware components. Which may implement or perform the various methods, steps, and logic blocks disclosed in the embodiments of the present application. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.

The Memory 103 may include, but is not limited to, Random Access Memory (RAM), Read Only Memory (ROM), Programmable Read Only Memory (PROM), Erasable Read Only Memory (EPROM), electrically Erasable Read Only Memory (EEPROM), and the like.

It will be appreciated that the configuration shown in fig. 1 is merely illustrative and that the display device 100 may also include more or fewer components than shown in fig. 1 or have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof. In the embodiment of the present application, the display device 100 may be, but is not limited to, an entity device such as a desktop computer, a notebook computer, a smart phone, an intelligent wearable device, and a vehicle-mounted device, and may also be a virtual device such as a virtual machine.

It will be appreciated that the display device 100 also includes a display screen, which may be used to display images. The edge of the display screen on the display device 100 provided by the embodiment of the present application includes at least one rounded corner (the rounded corner refers to replacing the original corner with a section of circular arc tangent to both sides of the corner), and because the pixel point where the rounded corner is located is displayed incompletely, the edge of the image may have color cast when the image is displayed on the display screen. Therefore, the embodiment of the present application provides an image data processing method to solve the problem of color cast phenomenon occurring at the edge when the display device 100 displays an image.

The general process for solving the above problems is as follows: for different display devices, storing fillet edge coefficients corresponding to pixel points (for convenience of description, referred to as edge pixel points in the following embodiments) where fillets are located on a display screen in the display devices; reading the stored fillet edge coefficient when the display device displays the image; and processing the image data by using the fillet edge coefficient.

It is to be understood that, when the edge of the display screen includes a plurality of rounded corners, the above-mentioned processes may be sequentially performed for each rounded corner, or may be performed simultaneously, and this is not specifically limited in this embodiment of the application.

It can be seen that, in the above flow, if the stored fillet edge coefficients are more, there are problems that the number of memories required is more, and the corresponding hardware area is larger, thereby increasing the cost; the problems of high complexity and long time consumption of the process of reading and writing the fillet edge coefficient can also exist. Therefore, based on the above analysis, the image data processing provided by the embodiment of the present application can reduce the amount of data stored in the display device to reduce the cost and the complexity of data reading.

It should be noted that the image data processing method provided in the present application can only be implemented on the display device 100 that satisfies certain conditions, where the conditions are as follows: the pixel points positioned in the middle of the edge pixel points are called as middle pixel points, and the round corners at the edge of the display screen are symmetrical about the diagonal lines of the middle pixel points. Referring to fig. 2, fig. 2 is a schematic diagram of a fillet and an edge pixel point provided in an embodiment of the present disclosure, in which an oblique stripe square in fig. 2 represents a middle pixel point, a horizontal stripe square represents an edge pixel point located on an upper side of the middle pixel point, a vertical stripe square represents an edge pixel point located on a lower side of the middle pixel point, and the fillet passes through all of the oblique stripe square, the horizontal stripe square, and the vertical stripe square. It can be seen that the rounded corners are symmetrical about the diagonals of the cross-striped squares, and the number of the cross-striped squares is the same as the number of the vertical striped squares.

It can be understood that, when the edge of the display screen includes a plurality of rounded corners, only one of the rounded corners needs to satisfy the above conditions, and the display device may execute the image data processing method provided in the embodiment of the present application, but only the rounded corner that satisfies the conditions may store the rounded corner edge coefficient by using the rounded corner edge coefficient storage method in the image data processing method provided in the embodiment of the present application, and the rounded corner that does not satisfy the conditions may not use the rounded corner edge coefficient storage method.

In addition, the angle that the fillet corresponds in this application embodiment can be 90 degrees, 60 degrees or 120 degrees etc., and this application embodiment does not do specific restriction to this, only need the fillet satisfy above-mentioned condition can.

First, a method for storing a corner edge coefficient provided in an embodiment of the present application is described below, where the method is applied to a display device 100 that satisfies the above conditions.

Referring to fig. 3, fig. 3 is a flowchart of a fillet edge coefficient storage method according to an embodiment of the present disclosure, where the fillet edge coefficient storage method may include the following steps:

step S301: if the fillet is symmetrical about the diagonal, a first fillet edge coefficient and a second fillet edge coefficient are obtained.

Step S302: the first and second fillet edge coefficients are stored.

In an alternative embodiment, when the rounded corner is symmetrical about the diagonal line, that is, when the display device 100 satisfies the conditions in the above-described embodiment, the rounded corner edge coefficient of the middle pixel point is referred to as a first rounded corner edge coefficient, and the rounded corner edge coefficient (referred to as a second rounded corner edge coefficient) of the edge pixel point located on one side (referred to as a first side) of the middle pixel point is equal to the rounded corner edge coefficient (referred to as a third rounded corner edge coefficient) of the edge pixel point located on the other side (referred to as a second side) of the middle pixel point.

Therefore, in order to reduce the number of data stored in the display device, only the first rounded edge coefficient corresponding to the middle pixel point and the second rounded edge coefficient corresponding to the edge pixel point located on the first side of the middle pixel point may be stored, and the third rounded edge coefficient corresponding to the edge pixel point located on the second side of the middle pixel point may be determined according to the second rounded edge coefficient based on a symmetric structure. The manner of determination will be described in detail in the following embodiments, and will not be described here for the time being.

It can be understood that, for different rounded corners, there may be a plurality of combinations of the first side and the second side of the middle pixel point, for example: if the circle center of the fillet faces downwards to the right, the first side of the middle pixel point can be the upper side of the fillet, and the second side of the middle pixel point can be the lower side of the fillet; if the circle center of the fillet still faces to the lower right side, the first side of the middle pixel point can also be the lower side of the fillet, and the second side of the middle pixel point can be the upper side of the fillet; if the fillet centre of a circle upwards towards right, then the first side of middle pixel can be fillet upside, the second side of middle pixel can be fillet downside etc. this application embodiment does not do specific restriction to this.

In addition, in the above embodiment, "only store the first rounded edge coefficient corresponding to the middle pixel point and the second rounded edge coefficient corresponding to the edge pixel point located on the first side of the middle pixel point" is an example provided in the embodiment of the present application, and only store the first rounded edge coefficient corresponding to the middle pixel point and the third rounded edge coefficient corresponding to the edge pixel point located on the second side of the middle pixel point, and then determine the second rounded edge coefficient according to the third rounded edge coefficient, which is also not specifically limited in this application.

For convenience of description, in subsequent embodiments, the fillet shown in fig. 2 is used as an example for explanation, that is, an angle corresponding to the fillet is 90 degrees, a circle center of the fillet faces downward to the right, an edge pixel point located on an upper side of a middle pixel point is an edge pixel point located on a first side of the middle pixel point, an edge pixel point located on a lower side of the middle pixel point is an edge pixel point located on a second side of the middle pixel point, and a radius of the fillet is a length of nine pixel points.

Therefore, when the fillet is symmetrical about the diagonal, the display device can obtain a first fillet edge coefficient corresponding to the middle pixel point and a second fillet edge coefficient corresponding to the edge pixel point on the first side of the middle pixel point, and store the first fillet edge coefficient and the second fillet edge coefficient into the display device, so that the display device can read the prestored fillet edge coefficient to process image data when displaying images.

It should be noted that there are various ways for the display device to obtain the first round edge coefficient and the second round edge coefficient, for example: receiving data input by a user; reading data stored in a database; reading data stored in local equipment; and calculating to obtain data, and the like, which is not specifically limited in the embodiments of the present application and can be appropriately selected by those skilled in the art according to actual situations.

Taking the second fillet edge coefficient calculated by the display device as an example, the step S301 may include the following steps:

the method comprises the following steps of firstly, calculating the ratio of a first area to the total area of pixel points in edge pixel points on a first side.

And secondly, determining the ratio as a second fillet edge coefficient.

As shown in fig. 2, the edge pixel point located on the first side of the center pixel point is divided into two regions, the two regions have the first area and the second area, and the region corresponding to the first area is located on one side of the edge pixel point located on the first side and close to the circle center of the fillet (i.e., the region surrounded by the fillet and the edge pixel point located on the first side).

Therefore, the fillet edge coefficient can be determined according to the ratio of the area enclosed by the fillet and each pixel point in the edge pixel points to the total area of the pixel points, so that the image data is processed, and the phenomenon of edge color cast is reduced.

In the scheme, aiming at the symmetrical fillets of the diagonals of the middle pixel points, in the storage process, the display equipment can only store the first fillet edge coefficient corresponding to the middle pixel point and the second fillet edge coefficient corresponding to the edge pixel point positioned on the first side of the middle pixel point, and the fillet edge coefficients corresponding to all the edge pixel points are not required to be stored, so that the number of memories for storing the fillet edge coefficients in the display equipment can be reduced, and the cost is reduced.

An image data processing method provided by an embodiment of the present application, which is also applied to the display device 100 satisfying the above-described conditions, is described below.

Referring to fig. 4, fig. 4 is a flowchart of an image data processing method according to an embodiment of the present disclosure, where the image data processing method includes the following steps:

step S401: when image data are obtained, a first fillet edge coefficient corresponding to a prestored middle pixel point and a second fillet edge coefficient corresponding to an edge pixel point positioned on the first side of the middle pixel point are obtained.

Step S402: and determining a third fillet edge coefficient corresponding to the edge pixel point on the second side of the middle pixel point according to the first fillet edge coefficient and the second fillet edge coefficient.

Step S403: and processing the image data by utilizing the first fillet edge coefficient, the second fillet edge coefficient and the third fillet edge coefficient.

In alternative embodiments, similar to obtaining the rounded edge coefficients, the display device may obtain the image data in various ways, such as: receiving data input by a user; reading data stored in a database; reading data stored in local equipment; the method includes acquiring an image, and the like, which is not specifically limited in the embodiments of the present application, and those skilled in the art may appropriately select the image according to actual situations.

When the display device acquires the image data and needs to display an image corresponding to the image data, the fillet edge coefficient may be acquired and the image data may be processed by using the fillet edge coefficient, that is, the above steps S401 to S403 are performed. Each step in the above-described flow is described in detail below.

First, the step of obtaining the first and second corner rounding coefficients (i.e., step S401) will be described. The step S401 may include the following steps:

and sequentially reading the first rounded edge coefficient and the second rounded edge coefficient according to a preset sequence, and respectively determining the corresponding relation between the middle pixel point and the first rounded edge coefficient and the corresponding relation between the edge pixel point on the first side and the second rounded edge coefficient according to the first rounded edge coefficient and the second rounded edge coefficient.

In an alternative embodiment, the preset order may be an order of storing the fillet edge coefficients, that is, the fillet edge coefficients stored in the first storage are read first, then the fillet edge coefficients stored in the second storage are read, then the fillet edge coefficients stored in the third storage are read, and so on until all the fillet edge coefficients are read. It will be appreciated that the preset order may also be other orders, for example: the order of the positions of the edge pixels corresponding to the rounded edge coefficients, and the like are set manually, and this is not specifically limited in the embodiments of the present application.

The storage sequence of the fillet edge coefficients can be determined by the relation between the fillet and the pixel points. Taking fig. 2 as an example, the value of the first rounded edge coefficient corresponding to the middle pixel point in fig. 2 is c1, and the values of the rounded edge coefficients corresponding to the edge pixel points located on the first side of the middle pixel point are a5, a4, a3, a2, a1, b2, b1, and c2 from right to left. Assuming that the number of rows and the number of columns of the pixel point corresponding to a5 are 1, the order of storing the fillet edge coefficients may be: a5, a4, a3, a2, a1, b2, b1, c2 and c1, namely, the storage is carried out in the order of increasing the number of columns and increasing the number of rows. Thus, when the corner edge coefficients are read, the order of reading is also a5, a4, a3, a2, a1, b2, b1, and c 2.

As an embodiment, the corresponding relationship between the middle pixel point and the first rounded edge coefficient and the corresponding relationship between the edge pixel point on the first side and the second rounded edge coefficient may be stored in the display device; as another embodiment, the correspondence between the middle pixel point and the first rounded edge coefficient and the correspondence between the edge pixel point on the first side and the second rounded edge coefficient need to be determined according to the first rounded edge coefficient and the second rounded edge coefficient.

With respect to the second embodiment, the step S401 may include the steps of:

the method comprises the following steps of firstly, sequentially reading a first fillet edge coefficient to an nth fillet edge coefficient from a first fillet edge coefficient and a second fillet edge coefficient; wherein n is an integer greater than 1, and the first rounded edge coefficient corresponds to edge pixel points with 1 row and 1 column.

Secondly, if the a-th fillet edge coefficient is smaller than the a-1-th fillet edge coefficient, determining that edge pixel points corresponding to the a-th fillet edge coefficient are pixel points with the same number of rows and the number of columns plus one as that of the edge pixel points corresponding to the a-1-th fillet edge coefficient; wherein a is an integer of n or less and greater than 1.

Thirdly, if the b-th fillet edge coefficient is larger than the b-1-th fillet edge coefficient, determining that edge pixel points corresponding to the b-th fillet edge coefficient are pixel points with the same number of rows plus one and the same number of columns of edge pixel points corresponding to the b-1-th fillet edge coefficient; wherein b is an integer less than or equal to n and greater than 1, and b is not equal to a.

Also, taking fig. 2 as an example, the first to eighth fillet edge coefficients (i.e., n ═ 8) of the first and second fillet edge coefficients are read in the order of a5, a4, a3, a2, a1, b2, b1, and c 2.

The second fillet edge coefficient a4 is smaller than the first fillet edge coefficient a5 (i.e. a equals 2), and then a5 has a row number of 1 and a column number of 2 corresponding to the edge pixel. The determination manner of the edge pixel point corresponding to the third fillet edge coefficient a3 (the number of rows is 1 and the number of columns is 3), the fourth fillet edge coefficient a1 (the number of rows is 1 and the number of columns is 4), and the fifth fillet edge coefficient a1 (the number of rows is 1 and the number of columns is 5) is similar to the determination manner of the edge pixel point corresponding to the second fillet edge coefficient a 4. The sixth fillet edge coefficient b2 is greater than the fifth fillet edge coefficient a1 (i.e. b equals 6), and then b2 has a row number of 2 and a column number of 5 corresponding to the edge pixels. The determination mode of the edge pixel corresponding to the seventh rounded edge coefficient b1 (the number of rows is 2 and the number of columns is 6) is similar to the determination mode of the edge pixel corresponding to the second rounded edge coefficient a4, the determination mode of the edge pixel corresponding to the eighth rounded edge coefficient c2 (the number of rows is 3 and the number of columns is 6) is similar to the determination mode of the edge pixel corresponding to the sixth rounded edge coefficient b2, the determination mode of the edge pixel corresponding to the ninth rounded edge coefficient c1 (namely, the intermediate pixel) (the number of rows is 3 and the number of columns is 7) (namely, the intermediate pixel) is similar to the determination mode of the edge pixel corresponding to the second rounded edge coefficient a4, and details are not repeated here.

At this point, the first rounded edge coefficient, the second rounded edge coefficient, the corresponding relationship between the first rounded edge coefficient and the middle pixel point, and the corresponding relationship between the second rounded edge coefficient and the edge pixel point located on the first side of the middle pixel point are all determined.

In the above scheme, because only the first rounded edge coefficient corresponding to the middle pixel point and the second rounded edge coefficient corresponding to the edge pixel point on the first side of the middle pixel point are stored, based on the characteristic that the rounded edge coefficients on the two sides of the middle pixel point are sequentially increased in the row direction or are sequentially increased in the column direction, the stored rounded edge coefficients can be sequentially read out so as to correspond the rounded edge coefficients to the edge pixel points.

Next, a step of obtaining a third fillet edge coefficient from the first fillet edge coefficient and the second fillet edge coefficient (i.e., step S402) will be described. The step S402 may include the following steps:

and reading the second fillet edge coefficient according to the sequence opposite to the preset sequence, and determining a third fillet edge coefficient and the corresponding relation between the edge pixel point of the second side and the third fillet edge coefficient according to the second fillet edge coefficient.

In an optional embodiment, since the edge pixel point corresponding to the third rounded edge coefficient and the edge pixel point corresponding to the second rounded edge coefficient are symmetric with respect to the diagonal of the middle pixel point, the second rounded edge coefficient may be read in an order opposite to the preset order to obtain the third rounded edge coefficient. The preset sequence has been described in detail in the above embodiments, and is not described herein again.

Taking fig. 2 as an example, assuming that the number of rows and the number of columns of the pixel corresponding to a5 are 1, the order of storing the corner edge coefficients may be: a5, a4, a3, a2, a1, b2, b1, c2 and c1, namely, the storage is carried out in the order of increasing the number of columns and increasing the number of rows. Thus, when the corner edge coefficients are read, the order of reading is c2, b1, b2, a1, a2, a3, a4, a 5.

Similar to the embodiment in step S401, the corresponding relationship between the edge pixel point on the second side and the third fillet edge coefficient may be stored in the display device; as another embodiment, the correspondence between the edge pixel point on the second side and the third fillet edge coefficient needs to be determined according to the first fillet edge coefficient and the second fillet edge coefficient.

With respect to the second embodiment, the step S402 may include the following steps:

the method comprises the following steps of firstly, if the nth fillet edge coefficient is the last fillet edge coefficient in the first fillet edge coefficient and the second fillet edge coefficient, sequentially reading the (n-1) th fillet edge coefficient from the first fillet edge coefficient and the second fillet edge coefficient to the first fillet edge coefficient.

Secondly, if the c-1 th fillet edge coefficient is smaller than the c-1 th fillet edge coefficient, determining that edge pixel points corresponding to the c-1 th fillet edge coefficient are pixel points with the same number of rows and the number of columns plus one as the edge pixel points corresponding to the c-1 th fillet edge coefficient; wherein c is an integer of n or less and greater than 1.

Thirdly, if the d-1 th fillet edge coefficient is larger than the d-1 th fillet edge coefficient, determining that the edge pixel point corresponding to the d-1 th fillet edge coefficient is a pixel point with the same number of rows plus one and columns as the edge pixel point corresponding to the d-1 th fillet edge coefficient; wherein d is an integer less than or equal to n and greater than 1, and d is not equal to c.

Similarly, taking fig. 2 as an example, the seventh to first fillet edge coefficients of the second fillet edge coefficients are read sequentially in the order of c2, b1, b2, a1, a2, a3, a4, and a5 (i.e., n is 8).

The eighth corner edge coefficient c2 is greater than the ninth corner edge coefficient c1 (i.e., d is 9), so that c2 has a row number of 4 and a column number of 7. The seventh corner edge coefficient b1 is smaller than the eighth corner edge coefficient c2 (i.e., c is 8), so the number of rows and columns of edge pixels corresponding to b1 is 4 and 8. A determination manner of an edge pixel corresponding to the sixth fillet edge coefficient b2 (row number is 5 and column number is 8), a fourth fillet edge coefficient a2 (row number is 6 and column number is 9), a third fillet edge coefficient a3 (row number is 7 and column number is 9), a second fillet edge coefficient a4 (row number is 8 and column number is 9), and a first fillet edge coefficient a5 (row number is 9 and column number is 9) is similar to that of an edge pixel corresponding to the eighth fillet edge coefficient c2, a determination manner of an edge pixel corresponding to the fifth fillet edge coefficient a1 (row number is 5 and column number is 9) is similar to that of an edge pixel corresponding to the seventh fillet edge coefficient b1, and details are not repeated here.

And determining the corresponding relation among the third fillet edge coefficient, the third fillet edge coefficient and the edge pixel point positioned on the second side of the middle pixel point.

In the above scheme, since only the first rounded edge coefficient corresponding to the middle pixel point and the second rounded edge coefficient corresponding to the edge pixel point located on the first side of the middle pixel point are stored, based on the characteristic that the rounded edge coefficients located on the two sides of the middle pixel point are sequentially increased in the row direction or are sequentially increased in the column direction, the stored rounded edge coefficients can be sequentially read out so as to correspond the rounded edge coefficients to the edge pixel points.

Finally, a step of processing the image data using the first rounded edge coefficient, the second rounded edge coefficient, and the third rounded edge coefficient (i.e., step S403) will be described. The step S403 may include the following steps:

and multiplying the fillet edge coefficient corresponding to the edge pixel point with the input gray value corresponding to the edge pixel point to obtain an output gray value.

In the above scheme, the round corner edge coefficient may be multiplied by the additional input gray value corresponding to the corresponding edge pixel point to obtain the output gray value, so as to process the image data and reduce the edge color cast.
