Description

Signal processing method, device, electronic equipment and storage medium

Technical Field

The present application relates to the field of touch screens, and in particular, to a signal processing method, a signal processing device, an electronic device, and a storage medium.

Background

Currently, for a certain user equipment with a touch screen, such as a mobile phone, there are an original touch screen and a non-original touch screen; instead of the original touch screen, the number of channels in the lateral or longitudinal direction of the original touch screen is generally different. For example, the number of channels of the non-original touch screen in the transverse direction is 18, and the number of channels in the longitudinal direction is 32, and at this time, the number of nodes formed by the channels of the non-original touch screen is 32×18; the number of channels of the original touch screen in the transverse direction is 18, and the number of channels of the original touch screen in the longitudinal direction is 36, and at this time, the number of nodes formed by the channels of the original touch screen is 36×18. For the mobile phone, the distribution of the adapted channels is 36 rows and 18 columns corresponding to the original touch screen, but the distribution of the channels of 32 rows and 18 columns corresponding to the original touch screen is not adapted to the mobile phone.

When the mobile phone adopts a non-original touch screen, a user can acquire a touch signal corresponding to each node in a touch area when touching the non-original touch screen; then, sending a touch signal corresponding to each node in the touch area to an application processor (Application Processor, AP) of the mobile phone; the AP of the mobile phone calculates the corresponding coordinates of the touch area, namely the touch position of the user, based on the touch signal of each node in the touch area received from the non-original touch screen.

However, since the non-original touch screen is not adapted to the mobile phone, the deviation between the coordinate calculated based on the touch signal of each node in the touch area received from the non-original touch screen and the real coordinate is large, for example, the real coordinate corresponds to the application a (i.e. the application the user really wants to click on), the calculated coordinate corresponds to the application B, and then the AP of the mobile phone will respond to the touch of the user for the application B, not the touch of the application a, so that the accuracy of determining the touch position of the user when the user touches on the non-original touch screen is reduced. Therefore, how to improve the accuracy of determining the touch position of the user when the user touches the non-original touch screen is a problem to be solved.

First, in order to facilitate understanding of the embodiments of the present application, related terms to which the present application relates are explained and explained first.

Original touch screen and non-original touch screen: the original touch screen is a screen which is not modified and can be perfectly adapted to the electrical equipment (such as a mobile phone), the non-original screen is a modified screen, and the modified screen has the problems of insensitivity, inaccurate touch precision and the like; in addition, the original touch screen and the non-original touch screen of the same electronic device have the same size and different channel numbers.

Referring to fig. 2, fig. 2 is a schematic diagram of a signal processing system according to an embodiment of the application. The signal processing system comprises a first processor 201 and a second processor 202; the first processor 201 is located on a non-original touch screen, and the second processor 202 is a processor of a user device (such as a mobile phone, a tablet, a computer, etc.), where the second processor 202 may be an application processor of the user device, and is mainly used for data processing and the like. It can be understood that after the original touch screen of the user equipment is damaged, the non-original touch screen can be installed on the user equipment to be used as the touch screen of the user equipment; the first processor 201 and the second processor 202 establish a communication connection, and the manner of the communication connection is not limited by the present application. In addition, the appearance information such as the shape and pattern of the first processor 201 and the second processor 202 shown in fig. 2 is merely an example, and the present application is not limited thereto; and the specific location of the first processor 201 on the non-original touch screen is not limited by the present application, and the specific location of the second processor 202 on the user device is not limited by the present application, and the location of the first processor 201 on the non-original touch screen and the location of the second processor 202 on the user device in fig. 2 are only examples.

For a certain user device, such as a mobile phone, when a non-original touch screen is adopted and a touch is generated on the non-original touch screen, the first processor 201 processes a first touch signal corresponding to each node in the touch area to obtain a second touch signal corresponding to each node in the touch area, and then the first processor 201 sends the second touch signal corresponding to each node in the touch area to the second processor 202, specifically:

first, the first processor 201 obtains a first channel number a of the non-original touch screen in a transverse direction and a second channel number b of the non-original touch screen in a longitudinal direction, wherein the node numbers formed by the channels of the non-original touch screen in the transverse direction and the longitudinal direction are a×b; the method comprises the steps of obtaining a first touch signal corresponding to each node in a plurality of nodes in a touch area, wherein the first touch signal corresponding to each node in the plurality of nodes in the touch area forms a matrix of c, c is more than or equal to 1 and less than or equal to b, and d is more than or equal to 1 and less than or equal to a; acquiring a third channel number e of the original touch screen in the transverse direction and a fourth channel number f of the original touch screen in the longitudinal direction; then, the first processor 201 determines a target direction and a first ratio corresponding to the target direction based on a, b, e and f, wherein the target direction comprises a transverse direction and/or a longitudinal direction, and the first ratio is a ratio of the number of channels of the original touch screen in the target direction to the number of channels of the non-original touch screen in the target direction; then, the first processor 201 determines a second touch signal corresponding to each node in the touch area based on the target direction, the first ratio, and the first touch signal corresponding to each node in the plurality of nodes in the touch area; finally, the first processor 201 sends a second touch signal corresponding to each node in the touch area to the second processor 202, so that after receiving the second touch signal corresponding to each node in the touch area, the second processor 202 calculates coordinates of the touch area based on the second touch signal corresponding to each node, and then responds to the touch of the user on the non-original touch screen based on the coordinates.

It can be seen that, in the embodiment of the present application, by acquiring the first channel number a of the non-original touch screen in the transverse direction and the second channel number b of the non-original touch screen in the longitudinal direction, the node number formed by the channels of the non-original touch screen in the transverse direction and the longitudinal direction is a×b; the method comprises the steps of obtaining a first touch signal corresponding to each node in a plurality of nodes in a touch area, wherein the first touch signal corresponding to each node in the plurality of nodes in the touch area forms a matrix of c, c is more than or equal to 1 and less than or equal to b, and d is more than or equal to 1 and less than or equal to a; acquiring a third channel number e of the original touch screen in the transverse direction and a fourth channel number f of the original touch screen in the longitudinal direction; then, determining a target direction and a first ratio corresponding to the target direction based on a, b, e and f, wherein the target direction comprises a transverse direction and/or a longitudinal direction; then, determining a second touch signal corresponding to each node in the touch area based on the target direction, the first ratio and the first touch signal corresponding to each node in the touch area; that is, based on a, b, e and f, determining a target direction, then processing a first touch signal corresponding to a node corresponding to a channel of the touch area in the target direction based on a first ratio to obtain a second touch signal corresponding to each node in the touch area, that is, determining the target direction based on the number of channels of the original touch screen and the non-original touch screen, and then processing the first touch signal corresponding to each node in the touch area under the angle of the non-original touch screen to obtain a second touch signal corresponding to each node in the touch area under the angle of the original touch screen or adapted to user equipment (such as a mobile phone, a tablet, a computer and the like) with the touch screen; and finally, sending a second touch signal corresponding to each node in the touch area to the second processor, so that the second processor calculates the coordinates of the touch area in the target direction based on the second touch signal corresponding to each node in the touch area, for example, if the target direction is transverse, the abscissa of the touch area is calculated, and at the moment, the coordinates in the target direction are the same as the real coordinates in the target direction or have small deviation from the real coordinates in the target direction, thereby improving the accuracy of determining the touch position of the user when the user touches the non-original touch screen.

Referring to fig. 3, fig. 3 is a flowchart of a signal processing method according to an embodiment of the present application, where the method is applied to a first processor, and the first processor is located on a non-original touch screen, and includes, but is not limited to, steps 301 to 306:

301: the first processor acquires a first channel number a of the non-original touch screen in the transverse direction and a second channel number b of the non-original touch screen in the longitudinal direction.

The node number formed by the channels of the non-original touch screen in the transverse direction and the longitudinal direction is a, and a and b are positive integers. For example, referring to the example of fig. 1, as shown in fig. 1, the number of first channels of the non-original touch screen in the transverse direction is a (i.e. 1, 2, 3, 4, 5, 6, 7, 8, 9, …, a), the number of second channels in the longitudinal direction is b (i.e. 1, 2, 3, 4, 5, 6, 7, 8, …, b), and at this time, the number of nodes formed by the a channels in the transverse direction and the b channels in the longitudinal direction is a×b, which can be understood as a×b nodes respectively correspond to a×b rectangular small lattices in fig. 1.

302: the first processor acquires a first touch signal corresponding to each of a plurality of nodes in the touch area.

The first touch signal corresponding to each node in the plurality of nodes in the touch area forms a matrix of c x d, namely a matrix of c rows and d columns, c and d are positive integers, c is more than or equal to 1 and less than or equal to b, d is more than or equal to 1 and less than or equal to a, namely the number of the plurality of nodes in the touch area is c x d. For example, based on the schematic diagram of fig. 1, referring to fig. 4, fig. 4 is a schematic diagram of a first touch signal corresponding to each node in a touch area according to an embodiment of the present application, as shown in fig. 4, a "solid shadow circle" is a touch area corresponding to a touch of a non-original touch screen, and the area of the "solid shadow circle" totally involves 9 nodes: namely, a node of a 5 th channel in the transverse direction and a 4 th channel in the longitudinal direction, a node of a 5 th channel in the transverse direction and a 5 th channel in the longitudinal direction, a node of a 5 th channel in the transverse direction and a 6 th channel in the longitudinal direction, a node of a 6 th channel in the transverse direction and a 5 th channel in the longitudinal direction, a node of a 6 th channel in the transverse direction and a 6 th channel in the longitudinal direction, a node of a 7 th channel in the transverse direction and a 4 th channel in the longitudinal direction, a node of a 7 th channel in the transverse direction and a 5 th channel in the longitudinal direction, and a node of a 7 th channel in the transverse direction and a 6 th channel in the longitudinal direction; therefore, the plurality of nodes in the touch area, which is the rectangle of 3*3 in fig. 4, are the above 9 nodes, the first touch signal corresponding to each node of the 9 nodes in the touch area forms a matrix of 3*3 (at this time, c=3, d=3), and the first touch signals corresponding to each node of the 9 nodes are respectively: s11, S12, S13, S21, S22, S23, S31, S32, S33.

303: the first processor acquires a third channel number e of the original touch screen in the transverse direction and a fourth channel number f of the original touch screen in the longitudinal direction.

In an embodiment of the application, wherein e and f are both positive integers; the number of channels in the lateral and longitudinal directions of the original touch screen may be stored in advance. Thus, the original touch screen can be obtained with the number of channels e in the transverse direction and the number of channels f in the longitudinal direction.

304: the first processor determines a target direction and a first ratio corresponding to the target direction based on a, b, e, and f.

The target direction includes a transverse direction and/or a longitudinal direction, that is, the target direction may be a transverse direction, may be a longitudinal direction, and may also include a transverse direction and a longitudinal direction, where the first ratio is a ratio of a number of channels of the original touch screen in the target direction to a number of channels of the non-original touch screen in the target direction. Thus, step 204 may be embodied as: if a is not equal to e and b=f, determining the target direction as the transverse direction, and determining a first ratio corresponding to the transverse direction as the ratio of e to a; if a=e and b+.f, determining the target direction as the longitudinal direction, and determining the first ratio corresponding to the longitudinal direction as the ratio of f to b; if a is not equal to e and b is not equal to f, determining the target direction as the transverse direction and the longitudinal direction, determining the first ratio corresponding to the transverse direction as the ratio of e to a, and determining the first ratio corresponding to the longitudinal direction as the ratio of f to b. For example, if a=e and b+.f, the target direction is determined to be the longitudinal direction, and the first ratio=f/b corresponding to the longitudinal direction is determined, in practical application, how many decimal places the first ratio is reserved may be set in a custom manner to reduce the calculation.

It should be noted that, if the number of channels in the target direction is different between the original touch screen and the non-original touch screen, the coordinates in the target direction generated by the first touch signal of each node in the touch area and the real coordinates in the target direction are greatly different. For example, if the target direction is assumed to be only the vertical direction, the coordinate (i.e., Y coordinate) in the vertical direction (also understood as Y coordinate) generated based on the first touch signal of each node in the touch area is different from the real coordinate (i.e., real Y coordinate) in the vertical direction and has a large deviation, and the coordinate (i.e., X coordinate) in the horizontal direction (also understood as X coordinate) generated based on the first touch signal of each node in the touch area is the same as or has a small deviation from the real coordinate (i.e., real X coordinate) in the horizontal direction. Therefore, the first touch signal of each node in the touch area needs to be processed based on the longitudinal direction and the first ratio to obtain the second touch signal corresponding to each node in the touch area, at this time, the true Y coordinate deviation of the Y coordinate generated based on the second touch signal corresponding to each node in the touch area is very small and even the same, and it can be ensured that the X coordinate generated based on the second touch signal corresponding to each node in the touch area is unchanged, that is, the X coordinate is still the same as the X coordinate, that is, the Y coordinate identical to or smaller than the true Y coordinate is obtained, meanwhile, the X coordinate (that is, the same as the true X coordinate) is ensured to be unchanged, and further the touch precision, that is, the accuracy and the precision of determining the touch position are improved.

305: the first processor determines a second touch signal corresponding to each node in the touch area based on the target direction, the first ratio, and the first touch signal corresponding to each node in the touch area.

In the embodiment of the present application, step 305 may specifically refer to fig. 5, and fig. 5 is a flowchart of a method for determining a second touch signal corresponding to each node in a touch area according to the embodiment of the present application, including, but not limited to, steps 501-503:

501: and determining a third touch signal corresponding to each node in the ith dimension.

The matrix with the i-th dimension of c x d is the first or last dimension in the target direction, for example, when the target direction is transverse, the i-th dimension is the first or last column in the matrix with the c x d, and when the target direction is longitudinal, the i-th dimension is the first or last row in the matrix with the c x d. For example, based on the above example, referring to fig. 6, fig. 6 is a schematic diagram of determining a third touch signal corresponding to each node in the ith dimension according to the embodiment of the present application, as shown in fig. 6, assuming that a matrix of c×d is a matrix of 3*3 in fig. 6 (including 9 first touch signals corresponding to 9 nodes in a touch area), 9 elements in the matrix of 3*3 are 9 first touch signals corresponding to 9 nodes (i.e. S11, S12, S13, S21, S22, S23, S31, S32, S33) respectively in sequence: 68. 149, 148, 90, 255, 70, 151, 150; if a=18, b=32, e=18, f=36, the target direction is longitudinal, the first ratio is f/b=36/32=1.125; if the i-th dimension is the last dimension of the matrix of 3*3 in the longitudinal direction, i.e. i=3 at this time, the matrix of 3*3 determines that the third touch signals corresponding to each node in the 3-th dimension (i.e. 3 rd row) in the longitudinal direction are respectively: 70. 151, 150, i.e. the third touch signal corresponding to each node in row 3 corresponds to the first touch signal corresponding to each node in row 3 in the matrix of 3*3, respectively.

502: and determining a fourth touch signal corresponding to each node in the ith dimension based on the first ratio and the third touch signal corresponding to each node in the ith dimension.

In an embodiment of the present application, based on the assumptions and examples made above, step 502 may specifically include, but is not limited to, steps S11-S13:

s11: a first barycentric coordinate in the target direction is determined based on a first touch signal corresponding to each of a plurality of nodes in the touch region.

Based on the above example, if the target direction is vertical, the 9 first touch signals corresponding to the 9 nodes in the touch area are sequentially: 68. 149, 148, 90, 255, 70, 151, 150, or, in other words, the first touch signals corresponding to 3 nodes in the 1 st dimension (i.e. row 1) in the longitudinal direction in the matrix of 3*3 are 68, 149, 148 in turn, the first touch signals corresponding to 3 nodes in the 2 nd dimension (i.e. row 2) in the longitudinal direction are 90, 255 in turn, and the first touch signals corresponding to 3 nodes in the 3 rd dimension (i.e. row 3) in the longitudinal direction are 70, 151, 150 in turn; then, calculating first sums=68+149+148+90+255+255+70+151+150=1336 of 9 first touch signals corresponding to 9 nodes in the touch area; determining a second sum = (68+149+148) ×1+ (90+255) ×2+ (70+151+150) ×3=2678 based on the first touch signal in each row and the row corresponding to each row; the first barycentric coordinate in the longitudinal direction is then determined, i.e. the first barycentric Y coordinate is 2678/1336= 2.004491018 (here the reserved decimal places can be determined according to custom requirements).

S12: a second barycentric coordinate in the target direction is determined based on the first ratio and the first barycentric coordinate.

Illustratively, still based on the above examples and assumptions, since the first ratio is equal to 1.125 and the first barycentric coordinate is 2.004491018, the second barycentric coordinate in the machine direction, i.e., the second barycentric Y coordinate, is the product of the first ratio and the first barycentric coordinate, i.e., 1.125 x 2.004491018= 2.2550524 (where the reserved decimal numbers can be determined according to the custom requirements).

In the embodiment of the present application, step S13 specifically includes: first, third center coordinates in a target direction are determined based on first touch signals corresponding to each of the first remaining nodes. For example, still based on the above example, the first touch signal corresponding to each node in the first remaining nodes in the matrix of 3*3 except the first touch signal corresponding to each node in the 3 rd dimension (i.e., row 3) is the first touch signal corresponding to each node in row 1 in the matrix of 3*3 (i.e., 63, 149, 148) and the first touch signal corresponding to each node in row 2 (i.e., 90, 255); then, calculating a third sum=68+149+148+90+255+255=965 of the first touch signals corresponding to each node in the first remaining nodes except the first touch signal corresponding to each node in the 3 rd dimension in the matrix of 3*3, i.e., calculating a third sum of the first touch signals corresponding to each node in the 1 st row and the 2 nd row; then, based on the first touch signal of each node in the 1 st row and the 2 nd row and the row number corresponding to each row (i.e. the row number corresponding to the 1 st row is 1 and the row number corresponding to the 2 nd row is 2), determining a fourth sum= (68+149+148) ×1+ (90+255+255) ×2=1565; thus, the third center of gravity, i.e., the third center of gravity, Y, coordinate in the machine direction is the ratio of the fourth sum to the third sum, 1565/965= 1.6217617 (here the reserved decimal place is determined according to the custom requirements).

Further, fourth center-of-gravity coordinates in the target direction are determined based on the third touch signal corresponding to each node in the i-th dimension. For example, still based on the above example, the third touch signal corresponding to each node in the 3 rd dimension (i.e. 3 rd row) is: 70. 151, 150, then a fifth sum = 70+151+150 = 371 is determined; then, based on the third touch signal corresponding to each node in the 3 rd row and the row number of the 3 rd row (the row number of the 3 rd row is 3), determining a sixth sum= (70+151+150) ×3=1113; thus, the fourth center-of-gravity coordinate in the longitudinal direction, i.e., the fourth center-of-gravity Y coordinate, is the ratio of the sixth sum to the fifth sum, i.e., 1113/371=3.

For example, still based on the above example and assumption, based on the fourth touch signal (i.e., 146, 337, 336) corresponding to each node in the 3 rd dimension (i.e., 3 rd row, i=3), and the first touch signal corresponding to each node in the first remaining nodes, i.e., the first touch signal corresponding to each node in the 3*3 matrix except the first touch signal corresponding to each node in the 3 rd dimension, i.e., the first touch signal corresponding to each node in the 1 st row (i.e., 68, 149, 148) and the first touch signal corresponding to each node in the 2 nd row (i.e., 90, 255), the second touch signal corresponding to 9 nodes in the touch area is determined, i.e., the first touch signal corresponding to each node in the 1 st row is determined as the second touch signal corresponding to each node in the 1 st row, the first touch signal corresponding to each node in the 2 nd row is determined as the second touch signal corresponding to each node in the 2 nd row, and the fourth touch signal corresponding to each node in the 3 nd row is determined as the second touch signal corresponding to each node in the fourth row. That is, the first touch signal corresponding to each node in the 1 st row and the 2 nd row in the matrix (i.e. in the touch area) of 3*3 is not changed, and only the first touch signal corresponding to each node in the 3 rd row is processed to obtain the second touch signal corresponding to each node in the 3 rd row, in this example, only the first touch signal corresponding to each node in the row needs to be changed, that is, only the first touch signal corresponding to each node in the row in the touch area needs to be processed, so that the calculation efficiency is accelerated.
