The color of the color taking area 10 is currently fixed singly, resulting in less selection by the user. It should be appreciated that different colors are represented in fig. 1 in different gray scales. In addition, when drawing a draft of a garment, as for a garment designer, not only the color of the garment but also the pattern of the garment need to be drawn, but the conventional electronic device has no pattern for the garment designer to select, so that the garment designer needs to manually draw the pattern, and the efficiency is low. In summary, in the prior art, the style of the handwriting displayed by the electronic device is single. It should be understood that "interface" and "graphical interface" in the embodiments of the present application are understood to be graphical user interfaces (graphical user interface, GUI) of electronic devices.

When the user goes out, a lot of attractive pictures are often shot, attractive patterns exist on the pictures, or the user sees the attractive patterns when browsing the webpage, if the user can timely extract the patterns on other devices for use in the electronic device, the user can draw handwriting without being limited by the original colors in the electronic device, and the user experience can be improved. Therefore, the embodiment of the application provides a cross-device drawing system, a user can select required colors and/or textures on a first device to extract the colors and/or textures required by the user to a second device, so that the user can directly use the colors and/or textures on the second device, the handwriting style of the electronic device can be enriched, and the drawing efficiency of the user is improved.

Fig. 2A is a schematic diagram of a cross-device drawing system according to an embodiment of the present application. Referring to fig. 2A, a first device and a second device may be included in the cross-device rendering system. Wherein the second device may be plural. Fig. 2A and the following embodiments illustrate a second device, and the first device is a mobile phone, and the second device is a tablet (portable android device, PAD). The first device and the second device may be interconnected by a communication network. The communication network may be, but is not limited to: WI-FI hotspot networks, WI-FI peer-to-peer (P2P) networks, bluetooth networks, zigbee networks, or near field communication (near field communication, NFC) networks.

Based on the above electronic device and the structure of the stylus, the cross-device drawing system provided in the embodiments of the present application is described below with reference to specific embodiments. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.

In one embodiment, the first device and the second device are both wirelessly connected to the stylus.

Referring to fig. 6, the interaction flow of the first device and the second device may include:

s601, the first device receives a first instruction, where the first instruction is used to instruct the first device to obtain texture information of a target area selected by the stylus.

In one embodiment, based on the embodiment shown in fig. 2B above, the texture information in the embodiment shown in fig. 6 may be replaced with color information, which is the color information of the first color of the target area (i.e., the first target area on the first device as described in fig. 2B above).

In one embodiment, when a user needs to acquire texture on a first device, the user may trigger the stylus to send a first instruction to the first device. Wherein the stylus may send the first instruction to the first device via the wireless or circuit path as above.

First, the user can hold the stylus to execute a first preset action to trigger the stylus to send a first instruction to the first device. In this embodiment, the stylus may detect an action of the stylus, and the stylus may send a first instruction to the first device in response to detecting that the user holds the stylus to perform a first preset action. It should be appreciated that the stylus may be configured with a G-sensor, gyroscope, etc., and the stylus may detect an action of the user holding the stylus based on data collected by the G-sensor, gyroscope, etc., to determine whether the user holds the stylus to perform the first preset action. Wherein the first preset actions may include, but are not limited to: shake, circle in the air, reverse the stylus, etc. Inverting the stylus can be understood as: the tail of the stylus is closer to the ground than the tip of the stylus. In the embodiment of the application, the touch pen is detected based on the data collected by the G-sensor, the gyroscope and the like, and the action of the touch pen is not repeated.

In one embodiment, a key may be disposed on the stylus, and the key may be a mechanical key or a touch key. When the stylus detects that the user operates the key, a first instruction may be sent to the first device.

In one embodiment, the first device receives the first command from the stylus if it detects that the stylus performs the second preset action.

First, the second preset action may be, but is not limited to,: the stylus double clicks the touch screen of the first device, or the stylus long presses the touch screen of the first device.

The second preset action may also be: the stylus draws a preset track on a touch screen of the first device. For example, the preset track may be preset characters, preset letters, preset shapes, or the like. In order to facilitate the first device to distinguish between the track drawn by the stylus and the preset track drawn by the stylus, the second preset action may be: the stylus draws a preset track in a preset area of the touch screen of the first device, which may be, but is not limited to, a central area of the touch screen. For example, if the first device detects that the stylus draws the preset letter m in the central area of the touch screen, it may be determined that a selection instruction from the stylus is detected, and if the first device detects that the stylus draws the preset letter m in other areas (non-preset areas) of the touch screen, it may be determined that the stylus draws a note, and m is displayed on corresponding positions in other areas of the touch screen. In the embodiment of the present application, the first device distinguishes between the track when the stylus draws the pen and the preset track drawn by the stylus, and the preset area is an example.

And secondly, a preset control, such as a texture taking control, can be displayed on the interface of the first device, and the first device can determine to receive the first instruction in response to detecting that the touch pen operates the preset control.

In one embodiment, the first device may determine to receive the first instruction if it detects that the user employs a finger or a finger joint to perform the second preset action, or if it detects that the user employs a finger or a finger joint to operate the preset control. That is, in the embodiment of the present application, the first instruction may be input to the first device by the user using a finger, a knuckle, or the like.

In one embodiment, the first device may detect whether the first device performs a third preset action, and the first device may determine to receive the first instruction in response to detecting that the first device performs the third preset action. Wherein the third preset action may include, but is not limited to,: shake, circle in the air, etc.

S602, the first device detects a target area selected by the stylus on an interface of the first device in response to receiving the first instruction.

It should be appreciated that the selection operation of the stylus on the interface of the first device may be referred to as a third user operation. The "interface of the first device" in S602 may be referred to as a second graphical interface.

The first device may detect a target area selected by the stylus on an interface of the first device in response to receiving the first instruction. As described above in relation to fig. 3-5, the first device may obtain the position of the stylus on the interface of the first device, and thus the first device may detect the target area selected by the stylus on the interface of the first device. It should be understood that the interface of the first device may be any interface, for example, an interface where the first device displays an image in an album of the first device, or an interface where the first device displays a web page, which is not limited in this embodiment of the present application, that is, in this embodiment of the present application, the target area may be selected by the stylus on any interface of the first device.

In this embodiment of the present application, the user may select the target area by using a manner of clicking the stylus on the interface of the first device, or drawing a preset shape, or the like. For example, when a user selects a target area in a click manner on an interface of the first device using a stylus, the first device may take as the target area a position clicked by the stylus. For example, when the user selects the target area with the stylus in such a manner as to draw a preset shape, the first device may determine that the area within the preset shape is the target area in response to detecting that the trajectory of the stylus is the preset shape.

It should be understood that S602 may be replaced with: the first device detects a target area selected by a user on an interface of the first device in response to receiving the first instruction. The user may select the target area on the interface of the first device by using a stylus, or may select the target area on the interface of the first device by using a finger, a knuckle, or the like. The following embodiments are described taking the example where the first device detects that the stylus selects the target area on the interface of the first device.

S602 can be understood as: the touch chip in the first device may obtain a target area selected by the touch pen on the interface of the first device based on the variation of the capacitance sampling value at the position corresponding to the TP sensor, and send the coordinates corresponding to the target area to the AP in the first device.

S603, the first device acquires texture information of the target area.

The first device may determine the content in the target area based on the content displayed by the interface of the first device and the location of the target area at the interface of the first device. The first device may analyze texture information of the target area based on content in the target area.

S603 can be understood as: and the AP extracts the content in the target area based on the coordinates corresponding to the target area and the content displayed on the interface of the first device. The AP may send the content in the target area to the GPU, which analyzes texture information of the target area in response to the content in the target area. The AP may intercept the content in the target area on the interface of the first device in a screenshot manner, and further send a screenshot including the content of the target area to the GPU. The following description uses the first device as an execution body for acquiring texture information of the target area, and describes a process of acquiring the texture information of the target area by the first device:

If the target area contains a plurality of identical patterns, the identical patterns in the target area can represent the texture of the target area, so that the first device can draw grids in the target area, acquire the patterns in each grid to detect whether the target area contains the identical patterns, and acquire the patterns if the target area contains the plurality of identical patterns. The first device may obtain a first similarity of patterns in each two grids, and detect whether a first similarity greater than or equal to a preset similarity exists. If the first similarity greater than or equal to the preset similarity exists, the first device also needs to detect the duty ratio of the first similarity greater than or equal to the preset similarity in all the first similarities, if the duty ratio is greater than or equal to the preset duty ratio, the target area is determined to contain the same pattern, and the same pattern in the grid corresponding to the greater than or equal to the preset similarity is used as the repeated pattern of the target area.

It should be appreciated that the grid drawn by the first device has a first preset size, which in one embodiment may be 1 pixel. If the first device does not have the first similarity greater than or equal to the preset similarity after drawing the grids, or if the duty ratio of the first device greater than or equal to the preset similarity is smaller than the preset duty ratio, the first device may continue to increase the size of the grids, and continue to acquire the second similarity of the patterns in each two grids, so as to detect whether the target area contains the same pattern. If the first device does not have the second similarity greater than or equal to the preset similarity after increasing the grids, or if the duty ratio of the second similarity greater than or equal to the preset similarity is smaller than the preset duty ratio, the first device may continue to increase the size of the grids, and continue to acquire the third similarity of the patterns in every two grids, so as to detect whether the target area contains the same pattern. And repeating the steps until the size of the grid reaches a second preset size, wherein the second preset size is half of the area of the target area, and the method for increasing the grid by the first device is not limited. It should be understood that, if the size of the grid reaches the second preset size, the first device may also not obtain a similarity greater than or equal to the preset similarity, or the ratio of the similarity greater than or equal to the preset similarity is smaller than the preset ratio, and then the first device may determine that the target area does not include the same pattern.

Thus, in one embodiment, if the first device is capable of acquiring a repeating pattern of the target area, the first device may capture an image of the repeating pattern, resulting in scalar data for the image of the repeating pattern. In one embodiment, if the first device is unable to acquire the repeated pattern of the target area, the first device may capture an image of the target area, resulting in scalar data for the image of the target area. In the embodiment of the application, in order to make the texture clear when the stylus draws the handwriting and uses the texture of the target area, the first device may convert the obtained scalar data into vector data. In one embodiment, the texture information includes vector data.

In fig. 7, taking a preset action of the touch pen to perform a shake in response to detecting that the touch pen is held by the user, the touch pen sends a first instruction to the first device, and referring to a in fig. 7, the user draws handwriting on a second device (such as a tablet computer) is illustrated. If the user wants to use the texture on the first device (handset), the user shakes a stylus, which can send a first instruction to the first device, see b in fig. 7. Referring to c of fig. 7, the interface of the first device is an interface displaying an image, and the user draws a circle on the interface using a stylus, and the first device may use an area in the circle as a target area. Illustratively, if the repetitive pattern of the target area is a triangle, the texture information obtained by the first device based on the description in S603 includes: vector data of triangles.

In one embodiment, the user may edit the texture of the target area in the first device, where the texture information obtained by the first device is texture information obtained after the user edits the texture of the target area. Illustratively, the editing process may be to adjust the depth of the texture of the target region, scale the texture of the target region, or the like.

Illustratively, in c of fig. 7, after the user draws a circle on the interface using the stylus, the first device may display a texture editing interface, as shown in fig. 8. A repeating pattern 81 in the target area, a depth editing control 82, and a scaling control 83 may be displayed on the editing interface. In fig. 8, the depth editing control 82 and the scaling control 83 are represented by a progress bar, and the user adjusts the progress bar to respectively adjust the depth of the texture of the target area and scale the texture of the target area. It should be appreciated that adjusting the depth of the texture of the target area may be understood as: and adjusting the contrast of the pattern of the target area and the background of the target area. The user can adjust the depth progress bar, reduce the contrast between the triangle and the background, and adjust the depth progress bar to amplify the triangle.

In this embodiment, the first device may acquire an edit processing parameter of a texture of the target area in the user, and correspondingly, the texture information obtained by the first device may include: editing the processing parameters. Referring to fig. 8, the texture information may include a depth parameter (80%) and a scale parameter (120%) in addition to vector data of triangles.

S604, the first device sends texture information to the stylus.

In an embodiment of the present application, a storage module may be included in the stylus, where the storage module is configured to store texture information from the first device.

In one embodiment, if the touch pen is provided with a display screen, after the touch pen receives texture information from the first device, a texture represented by the texture information may be displayed on the display screen. Illustratively, referring to d in FIG. 7, a triangle may be displayed on the display screen as a stylus.

S605, the stylus sends texture information to the second device.

In one embodiment, the stylus may send texture information to the second device in response to receiving the texture information from the first device.

In one embodiment, the tip of the stylus may be provided with a pressure sensor that may collect pressure data when the tip of the stylus contacts the touch screen of the second device. In this embodiment, in response to detecting that the pressure sensor collects pressure data, the stylus may determine that a tip of the stylus contacts the touch screen of the second device, which characterizes that a user needs to use the stylus to operate on the second device, and further the stylus may send texture information to the second device when contacting the touch screen of the second device.

In this manner, the second device may store texture information. In one embodiment, the second device includes a texture information memory therein, and the second device may store texture information in the texture information memory.

S606, the second device displays handwriting in the texture characterized by the texture information based on the position of the stylus on the touch screen.

When the stylus draws handwriting on the second device, the operation of drawing handwriting may be referred to as a fourth user operation, and the second device may detect a position of the stylus on a touch screen of the second device, and further display the handwriting on a corresponding position using a texture characterized by texture information from the stylus. After c in fig. 7 or fig. 8, if the user holds the stylus to draw handwriting on the second device, the second device may display the handwriting of the stylus in a triangle based on the position of the stylus on the touch screen, as shown with reference to d in fig. 7.

In one embodiment, the second device, upon receiving the texture information, may display the texture characterized by the texture information in a brush tool of the second device for user query and selection. Illustratively, an interface of an application program for drawing handwriting displayed on the second device is shown as a in fig. 9, and a brush tool 91, a "last step" control 92, a "history" control 93, a cancel control 94, and the like are displayed on the interface. If the second device is responsive to receiving texture information, a "triangle" texture may be stored in the brush tool 91 and the user operates the brush tool 91 with a stylus, the second device may display a plurality of selectable textures (including triangle texture 911, square texture 912, etc.) in the brush tool 91, as shown at b in fig. 9. It should be understood that b in fig. 9 represents the control in text, and the second device may also represent the control in a picture, a symbol, or the like, which is not limited in this embodiment of the present application. The stylus is not shown in fig. 9 a, b, d and e for clarity of illustration of the interface changes of the second device.

In one embodiment, the user may also select a texture and edit the selected texture. In b in fig. 9, the second device may also display a depth edit control 82, a zoom control 83, a resize control 95, an invert control 96, and the like. The depth editing control 82 and the scaling control 83 may refer to the related description of fig. 7, and the user may operate the control 95 according to the size adjustment ratio, so that the second device may adjust the size of the texture based on the thickness of the handwriting of the stylus. For example, the second device may increase the texture when the handwriting of the stylus is thickened. The user operates the inversion control 96 to invert the foreground and background, illustratively, if the texture is black and the background is white, then after inversion the texture is white and the background is black. Thus, the user can edit the selected texture, and correspondingly, the second device can display handwriting of the touch pen by adopting the edited texture based on the edit processing parameters of the texture by the user. It should be understood that the above editing process of the texture is an exemplary illustration, and the editing process manner of the texture is not limited in the embodiment of the present application.

It should be understood that the texture is characterized in shape for purposes of illustration in the embodiments of the present application.

When the user operates the "last step" control 92 with the stylus, the second device may query the used texture stored in the "history" and display the handwriting of the stylus with the last used texture. Referring to c in fig. 9, if the texture last used by the second device is square, the second device may display handwriting in square.

The cancel control 94 is used to cancel the currently drawn handwriting, and illustratively, when the user operates the cancel control 94 with the stylus, the second device may delete the handwriting of the stylus displayed in a triangle, as shown by e in fig. 9.

In one embodiment, S606 may be replaced with: the second device displays the handwriting in a texture characterized by texture information based on the position of the user's finger or knuckle on the touch screen.

It will be appreciated that the user may draw handwriting on the touch screen of the second device using a finger or knuckle, and in such an embodiment the second device may detect the position of the user's finger or knuckle on the touch screen and further display the handwriting in texture characterized by texture information based on the position of the user's finger or knuckle on the touch screen.

In this embodiment, when a user draws handwriting on the second device by using the stylus, the texture may be selected on the first device by using the stylus, and the first device may send the texture selected by the stylus to the second device through the stylus.

It should be noted that when the first device is not wirelessly connected to the second device, the second device may send texture information to a third device wirelessly connected to the second device in response to receiving the texture information from the first device.

That is, synchronization of texture information may be established among the first device, the second device, and the third device, and the first device may send the texture information to the second device and the third device after acquiring the texture information, and the second device and the third device may update the stored texture information.

Correspondingly, the color information in the embodiment of the application is: color information of the repeated pattern. The color information of the repeated pattern includes: the RGB values for each location in the pattern are repeated.

In an embodiment, if the first device determines that the target area does not include the repetitive pattern, the texture information of the target area is vector data of an image of the target area, and the color information of the target area includes: RGB values for each location in the target area.

S1201 can refer to the description in S601. Unlike S601, the first instruction is used to instruct the first device to acquire texture information and/or color information of the target area selected by the stylus, and is not single texture information.

S1202, the first device detects a first target area and a third target area selected by the stylus on an interface of the first device in response to receiving the first instruction.

It should be appreciated that the operation of the stylus selecting the first target area on the interface of the first device may be referred to as a third user operation and the operation of the stylus selecting the third target area on the interface of the first device may be referred to as a seventh user operation. The "interface of the first device" in S1202 may be referred to as a second graphical interface.

Referring to b in fig. 14, if the first texture is triangle and the third texture is square, the fused texture is: the triangles are arranged on the right side of the square.

In one embodiment, the first device may fuse the first texture and the third texture in multiple ways, and exemplary fusing of the first texture and the third texture by the first device may not be limited to: the first device superimposes the first texture and the third texture, or the first device arranges the first texture to the right of the third texture, etc.

The first device may display a plurality of fused textures on an interface of the first device for selection by a user, where the user may select the fused textures on the interface of the first device, and thus, the first device uses texture information corresponding to the fused textures selected by the user as fused texture information in response to detecting the fused textures selected by the user.

In one embodiment, the user may customize the relative positions of the first texture and the third texture to perform a fusion process on the first texture and the third texture. If the first device obtains the first texture information and the third texture information, an editing interface may be displayed, where the editing interface includes the first texture and the third texture. Accordingly, the interface shown in fig. 8 may be replaced by the interface shown in fig. 15, referring to a in fig. 15, the editing interface displays a first texture in the first target area and a third texture in the third target area, the user may drag any one texture (the user may drag with a finger or a stylus) to change the relative positions of the first texture and the third texture, referring to b in fig. 15, the user may drag a square so that the square and the triangle are superimposed, and the fused textures are: superposition of squares and triangles.

Referring to b in fig. 13, when a user draws handwriting on the second device using the stylus, the second device may display the handwriting with a texture characterized by the fused texture information (i.e., the fused texture), and b in fig. 13 is illustrated by taking the superposition of the fused texture as a square and a triangle as an example.

In the embodiment of the application, the user can select at least two target areas on the first device by using the touch pen, the first device can fuse textures in the at least two target areas to obtain fused texture information, and then the fused texture information is synchronously fused to the second device, so that the user can fuse a plurality of textures which are needed, and the style of the handwriting displayed by the electronic device can be further enriched.

In this embodiment, S1203-S1206 in fig. 12 above may be replaced with S1203A-S1206A:

S1203A, the first device acquires first texture information of the first target region and third color information of the third target region.

In one embodiment, whether the first device acquires texture information or color information of the target area may be preset based on the order of the target area selected by the user.
