[0103] The pressure sensor 280A is used to sense the pressure signal and convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 280A can be disposed on the display screen 294.

[0104] There are many types of pressure sensors, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. Capacitive pressure sensors can be at least two parallel plates with conductive materials. When a force acts on the pressure sensor 280A, the capacitance between the electrodes changes. The electronic device 200 determines the intensity of the pressure based on the change in capacitance. When a touch operation acts on the display screen 294, the electronic device 200 detects the touch operation intensity according to the pressure sensor 280A. The electronic device 200 can also calculate the position of the touch based on the detection signal of the pressure sensor 280A. In some embodiments, touch operations acting on the same touch position but with different touch operation intensities can correspond to different operation instructions. For example: when a touch operation with a touch operation intensity less than the first pressure threshold acts on the short message application icon, an instruction to view the short message is executed. When a touch operation with a touch operation intensity greater than or equal to the first pressure threshold acts on the short message application icon, an instruction to create a new short message is executed.

The gyro sensor 280B can be used for anti-shake shooting. For example, when the shutter is pressed, the gyro sensor 280B detects the angle of the electronic device 200 shaking, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to offset the shaking of the electronic device 200 through reverse movement to achieve anti-shake. The gyro sensor 280B can also be used for navigation and somatosensory game scenes.

[0106] The air pressure sensor 280C is used to measure air pressure. In some embodiments, the electronic device 200 calculates the altitude through the air pressure value measured by the air pressure sensor 280C to assist in positioning and navigation.

[0107] The magnetic sensor 280D includes a Hall sensor. The electronic device 200 can use the magnetic sensor 280D to detect the opening and closing of the flip leather case. In some embodiments, when the electronic device 200 is a flip phone, the electronic device 200 can detect the opening and closing of the flip cover according to the magnetic sensor 280D.

[0108] The acceleration sensor 280E can detect the magnitude of the acceleration of the electronic device 200 in all directions (generally three axes). When the electronic device 200 is stationary, the magnitude and direction of gravity can be detected. It can also be used to identify the posture of the electronic device and is applied to applications such as horizontal and vertical screen switching and pedometers.

[0109] The distance sensor 280F is used to measure the distance. The electronic device 200 can measure the distance by infrared or laser. In some embodiments, when shooting a scene, the electronic device 200 can use the distance sensor 280F to measure the distance to achieve fast focusing.

[0110] The proximity light sensor 280G may include, for example, a light emitting diode (LED) and a light detector, such as a photodiode. The light emitting diode may be an infrared light emitting diode. The electronic device 200 emits infrared light outward through the light emitting diode. The electronic device 200 uses a photodiode to detect infrared reflected light from nearby objects. When sufficient reflected light is detected, it can be determined that there is an object near the electronic device 200. When insufficient reflected light is detected, the electronic device 200 can determine that there is no object near the electronic device 200. The electronic device 200 can use the proximity light sensor 280G to detect that the user holds the electronic device 200 close to the ear to talk, so as to automatically turn off the screen to save power. The proximity light sensor 280G can also be used in leather case mode and pocket mode to automatically unlock and lock the screen.

[0111] The ambient light sensor 280L is used to sense the ambient light brightness. The electronic device 200 can adaptively adjust the brightness of the display screen 294 according to the perceived ambient light brightness. The ambient light sensor 280L can also be used to automatically adjust the white balance when taking pictures.

[0113] The temperature sensor 280J is used to detect temperature. In some embodiments, the electronic device 200 uses the temperature detected by the temperature sensor 280J to execute a temperature processing strategy. For example, when the temperature reported by the temperature sensor 280J exceeds a threshold, the electronic device 200 reduces the performance of the processor located near the temperature sensor 280J to reduce power consumption and implement thermal protection. In other embodiments, when the temperature is lower than another threshold, the electronic device 200 heats the battery 242 to avoid abnormal shutdown of the electronic device 200 due to low temperature. In other embodiments, when the temperature is lower than another threshold, the electronic device 200 performs a boost on the output voltage of the battery 242 to avoid abnormal shutdown caused by low temperature.

[0114] The touch sensor 280K is also called a "touch control device". The touch sensor 280K can be set on the display screen 294. The touch sensor 280K and the display screen 294 form a touch screen, also called a "touch control screen". The touch sensor 280K is used to detect touch operations acting on or near it. The touch sensor can pass the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through the display screen 294. In other embodiments, the touch sensor 280K can also be set on the surface of the electronic device 200, which is different from the position of the display screen 294.

The bone conduction sensor 280M can also contact the human pulse to receive a blood pressure beat signal. In some embodiments, the bone conduction sensor 280M can also be set in an earphone and combined into a bone conduction earphone.

[0117] Motor 291 can generate vibration prompts. Motor 291 can be used for incoming call vibration prompts, and can also be used for touch vibration feedback. For example, touch operations acting on different applications (such as taking pictures, audio playback, etc.) can correspond to different vibration feedback effects. For touch operations acting on different areas of the display screen 294, motor 291 can also correspond to different vibration feedback effects. Different application scenarios (for example: time reminders, receiving messages, alarm clocks, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

[0118] Indicator 292 may be an indicator light, which may be used to indicate charging status, power changes, messages, missed calls, notifications, etc.

[0119] The SIM card interface 295 is used to connect a SIM card. The SIM card can be connected to and separated from the electronic device 200 by inserting it into the SIM card interface 295 or pulling it out from the SIM card interface 295. The electronic device 200 can support 1 or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 295 can support Nano SIM cards, Micro SIM cards, SIM cards, and the like. Multiple cards can be inserted into the same SIM card interface 295 at the same time. The types of the multiple cards can be the same or different. The SIM card interface 295 can also be compatible with different types of SIM cards. The SIM card interface 295 can also be compatible with external memory cards. The electronic device 200 interacts with the network through the SIM card to implement functions such as calls and data communications. In some embodiments, the electronic device 200 uses an eSIM, i.e., an embedded SIM card. The eSIM card can be embedded in the electronic device 200 and cannot be separated from the electronic device 200.

[0120] See also Figure 3 , is a schematic diagram of a method for generating a brush effect image provided by an embodiment of the present application, which can be applied to Figure 1 and Figure 2 The terminal device shown mainly includes the following steps.

[0121] Step S301: In response to an area selection operation on a display interface in a display screen, a pattern extraction area is determined in the display interface.

[0122] It is understandable that in actual application scenarios, before executing the brush effect image generation operation, the terminal device needs to be triggered to enter the brush effect image generation mode. The terminal device can be triggered to enter the brush effect image generation mode through the touch screen or buttons of the terminal device, or by inputting instructions through buttons on a touch input device.

[0123] See also Figure 4 , is a schematic diagram of a display interface provided in an embodiment of the present application. Figure 4 4 shows a display interface 401 of a terminal device and a pattern extraction area 402 in the display interface 401. In an optional embodiment, the area selection operation may be a circle selection operation performed by a user in the display interface 401. Specifically, the user uses a stylus to long-press the touch screen and slides on the touch screen, and the terminal device generates the pattern extraction area 402 according to the sliding path of the stylus.

[0124] It is understandable that the pattern extraction area 402 is a closed area surrounded by the sliding path. However, in actual operation, it is not easy for the user to draw a completely closed area on the touch screen. In the embodiment of the present application, in order to improve the convenience of operation, when the sliding path is not closed or there is an intersection, the terminal device fits the sliding path that is not closed or has an intersection into a closed path, and uses the fitted closed path as the pattern extraction area 402.

[0125] In addition, in order to enhance the user's sense of immersion when using the terminal device, when the user slides on the touch screen, the display interface 401 displays the user's sliding path in real time, and when the sliding is completed, the closed path fitted by the terminal device.

[0126] It is understandable that those skilled in the art may also determine the pattern extraction area in other ways, for example, when a user clicks on the touch screen, the terminal device fits a closed area in the display interface according to the click position, and uses the closed area as the pattern extraction area 402. When there is only one click position, a circular area centered on the click position may be used as the pattern extraction area 402, and the radius of the circular area may be adjusted according to actual needs, which is not limited in the present embodiment of the application.

[0127] Step S302: obtaining a first brush effect diagram according to the pattern extraction area, wherein the pattern of the first brush effect diagram is a pattern corresponding to the pattern extraction area in the display interface.

[0128] After determining the pattern extraction area, the embodiment of the present application analyzes the image in the pattern extraction area in the display interface to obtain a first brush effect map, which is the display content in the pattern extraction area in the display interface. It can be understood that the first brush effect map is a scalar map.

[0129] Step S303: obtaining a second brush effect image according to the first brush effect image, wherein the first brush effect image and the second brush effect image have the same pattern, and the clarity of the second brush effect image is greater than that of the first brush effect image.

[0130] In actual application scenarios, users may need to enlarge the brush effect image, for example, Figure 4 The heart-shaped pattern in the image is magnified and swiped to other positions in the display interface 401. However, the scalar image is easily blurred after being magnified.

[0131] See also Figure 5 , is a schematic diagram of a brush effect diagram provided in an embodiment of the present application. Figure 5501 and 502 are shown in FIG. 501 , wherein the first brush effect image 501 is the first brush effect image before being enlarged, and the first brush effect image 502 is the first brush effect image after being enlarged. Figure 5 As shown, after the first brush effect image is enlarged, the pattern becomes blurred and unclear, which cannot meet the needs of users.

[0132] To address this problem, in an embodiment of the present application, after obtaining a first brush effect image, a second brush effect image with higher definition is obtained based on the first brush effect image. Compared with the first brush effect image, the second brush effect image has a higher definition than the first brush effect image, and the second brush effect image and the first brush effect image have the same pattern or texture.

[0133] See also Figure 6 , is a schematic diagram of another brush effect diagram provided in an embodiment of the present application. Figure 6 6 shows a first brush effect image 601 and second brush effect images 602 and 603, wherein the second brush effect image 602 is the second brush effect image before enlargement, and the second brush effect image 603 is the second brush effect image after enlargement. Figure 6 As shown, since the second brush effect image has a higher definition, after the second brush effect image is enlarged, it still has a higher definition.

[0134] In order to achieve the above effect, the present application provides two implementation methods. First, a scalar image with higher resolution is obtained through the first brush effect image as the second brush effect image to improve the clarity of the second brush effect image; second, the first brush effect image is converted into a vector image to obtain the second brush effect image. The following is a detailed description.

[0135] For the first implementation method mentioned above, it can specifically include: training the neural network model through a large number of high-definition pattern and low-definition pattern data groups to obtain a trained neural network model; inputting the first brush effect image with a lower resolution into the trained neural network model, and outputting the second brush effect image with a higher resolution. It should be pointed out that the resolution here is a relative concept, which means that the resolution of the second brush effect image is higher than that of the first brush effect image. In addition, in addition to using a neural network model, those skilled in the art can also use other technical means to obtain the mapping relationship between high-definition patterns and low-definition patterns, that is, the mapping relationship between the first brush effect image and the second brush effect image, and then obtain the second brush effect image according to the first brush effect image and the mapping relationship between the first brush effect image and the second brush effect image. Without departing from the inventive concept of the present application, they should all fall within the scope of protection of the present application.

[0136] For the second implementation method mentioned above, it can specifically include: by linearizing the first brush effect image, obtaining an edge contour image of the pattern in the first brush effect image; obtaining edge contour points in the edge contour image, and continuous edge contour points constitute a polygon; performing curve fitting on the points of each polygon; drawing the fitted polygon, and filling with colors to obtain a vector image of the first brush effect image, which is the second brush effect image. It can be understood that the vector image will not be distorted after being enlarged, so the clarity of the second brush effect image is higher than that of the first brush effect image. In addition, the above-mentioned method of converting a scalar image into a vector image is only a specific implementation method listed in the embodiment of the present application. Those skilled in the art can use other technical means to realize the vectorization of the scalar image, and the embodiment of the present application does not limit this.

[0137] The brush effect image obtained by using the embodiment of the present application has higher clarity, thereby improving the user experience.

[0138] See also Figure 7 , is a flow chart of another method for generating a brush effect diagram provided in an embodiment of the present application. Figure 3 Expanding on the basis of the embodiment shown, Figure 3 Step S302 in the method: obtaining a first brush effect map according to the pattern extraction area, specifically includes the following steps.

[0139] Step S701: parsing the pattern of the pattern extraction area in the display interface;

[0140] Step S702: extracting a minimum repeating unit pattern from the analyzed pattern to obtain a first brush effect image.

[0141] It is understandable that when the user extracts the brush effect pattern in the display interface, there are usually many repeated pattern units in the display interface. For example, grass in grassland images, waves in sea images, wood grain in furniture images, etc. In this case, it is usually only necessary to obtain the minimum repeating unit pattern to meet the user's demand for the brush. In addition, by extracting the minimum repeating unit pattern, the influence of the edge on the brush effect image can also be reduced.

[0142] See also Figure 8 , is another schematic diagram of a display interface provided in an embodiment of the present application. Figure 88 shows a display interface 801 and a pattern extraction area 802, wherein the pattern extraction area 802 covers a complete "heart-shaped" pattern and two incomplete "heart-shaped" patterns in the display interface 801. If the image corresponding to the pattern extraction area 802 in the display interface 801 is directly used as the brush effect image, then the brush is used to draw in the display interface, and the effect is shown in the brush drawing pattern 803, in which there are two incomplete "heart-shaped" patterns. Obviously, the brush drawing pattern 803 is not the brush effect pattern that the user wants.

[0143] Therefore, after parsing the pattern of the pattern extraction area in the display interface, the embodiment of the present application extracts a minimum repeating unit pattern from the parsed pattern, and uses the minimum repeating unit pattern as the first brush effect image.

[0144] See also Fig. 9 , is a schematic diagram of extracting a minimum repeating unit pattern provided in an embodiment of the present application. Figure 8 After the pattern extraction area 802 in the illustrated embodiment is analyzed, a analyzed image 901 is obtained, and the analyzed image 901 corresponds to the image of the pattern extraction area 802 in the display interface 801. The minimum repeating unit pattern 902 extracted from the analyzed image 901 is a complete "heart-shaped" pattern, and the user can use the brush to draw a "heart-shaped" pattern at other locations on the display interface when applying the brush effect diagram.

[0145] In an alternative embodiment, Figure 4 or Figure 7 Expanding on the basis of the illustrated embodiment, after step S303, the method further includes the step of storing the second brush effect image.

[0146] In actual application scenarios, after the user has finished drawing with the current brush effect image, he may need to use the brush effect image again after a period of time. If you need to select a pattern extraction area in the display interface to regenerate the brush effect image before drawing with the brush effect image each time, it will not only be cumbersome to operate and affect the user experience, but also increase the performance overhead of the terminal device.

[0147] Based on this, after obtaining the second brush effect diagram, the embodiment of the present application stores the second brush effect diagram in the terminal device, and directly calls the stored second brush effect diagram during subsequent use.

[0148] Based on the above brush effect image generation method, the present application embodiment also provides an image editing method. Fig.10 , is a flow chart of an image editing method provided in an embodiment of the present application. The method can be applied to Figure 1 and Figure 2The terminal device shown mainly includes the following steps.

[0149] Step S1001: Generate a second brush effect graph, or call the first target brush effect graph.

[0150] Specifically, the second brush effect image is a second brush effect image generated by any method in the above embodiments, and the first target brush effect image is any one of the second brush effect images stored in the terminal device. When the user uses the brush to draw, on the one hand, he can enter the brush effect image generation mode to make a brush effect image; on the other hand, he can directly select a brush effect image from the second brush effect images stored in the terminal device for use.

[0151] See also Fig.11 , is another schematic diagram of a display interface provided in an embodiment of the present application. Fig.11 1 shows a display interface 1101 and a brush effect graph control 1102, which is used to identify a brush effect graph stored in a terminal device by a user. Figure 1 For the "heart-shaped" pattern, brush effect Figure 2 For the "triangle" pattern, brush effect Figure 3 It is a "five-pointed star" pattern.

[0152] When the user uses a brush to draw, on the one hand, he can enter the brush effect image generation mode to create a brush effect image; on the other hand, he can select a stored brush effect image in the brush effect image control 1102 by clicking the brush effect image control 1102. Figure 2 In the corresponding area, select the "triangle" pattern as the brush effect image of the current brush.

[0153] Step S1002: applying the second brush effect image or the first target brush effect image to a brush to draw a target image.

[0154] If the user enters the brush effect map generation mode, the generated second brush effect map is applied to the brush according to the user's area selection operation, and the target graphic is drawn; if the user calls the stored second brush effect map, the corresponding first target brush effect map is applied to the brush according to the user's operation, and the target graphic is drawn.

[0155] In addition, before using the brush to draw the target image, the user can also enlarge or reduce the brush effect image to draw a brush effect pattern of a corresponding size in the target image. Specifically, in response to the enlargement or reduction operation of the brush effect image, the second brush effect image is enlarged or reduced; the enlarged or reduced brush effect image is applied to the brush to draw the target image.

[0156] See also Fig.12 , is a flow chart of an image editing method provided in an embodiment of the present application. The method can be applied to Figure 1 and Figure 2 The terminal device and touch input device shown mainly include the following steps.

[0157] Step S1201: the terminal device sends a second brush effect image to the touch input device.

[0158] In adopting Figure 3 or Figure 7 After the method of the embodiment generates the second brush effect image, in addition to storing the second brush effect image in the terminal device, the second brush effect image may also be sent to the touch input device and stored in the touch input device.

[0159] Step S1202: the touch input device stores the second brush effect image.

[0160] After receiving the second brush effect image sent by the terminal device, the touch input device stores the second brush effect image in the touch input device.

[0161] Step S1203: the touch input device sends a second target brush effect image calling instruction to the terminal device in response to the second target brush effect image calling operation.

[0162] Specifically, the second target brush effect image calling instruction includes identification information of the brush effect image, and the terminal device can determine which second brush effect image needs to be called through the identification information. The user can trigger the second target brush effect image calling operation by pressing a button on the touch input device.

[0163] In an optional embodiment, the touch input device is provided with a display screen, and the touch input device can display the second brush effect image through the display screen, so that the user can filter the second brush effect image that he wants to call. For example, the display screen is a touch screen, and as the user slides his finger on the touch screen, the second brush effect image displayed on the touch screen keeps switching. When the user clicks the screen, the second target brush effect image calling instruction is triggered, and the second brush effect image currently displayed on the display screen is called.

[0164] Step S1204: The terminal device calls the second target brush effect image.

[0165] After receiving the second target brush effect picture calling instruction, the terminal device calls the corresponding second brush effect picture according to the identification information in the second target brush effect picture calling instruction.

[0166] Step S1205: the terminal device applies the second target brush effect image to the brush to draw the target image.

[0167] In the embodiment of the present application, the terminal device sends the brush effect image to the touch input device for backup, and the call operation of the brush effect image can be triggered by the touch input device.

[0168] See also Fig.13 , which is a software structure block diagram of the electronic device provided in an embodiment of the present application.

[0176] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0177] The notification manager enables applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as notifications of applications running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is displayed in the status bar, a prompt sound is emitted, an electronic device vibrates, an indicator light flashes, etc.

[0178] Android Runtime includes core libraries and virtual machines. Android runtime is responsible for scheduling and management of the Android system.

[0179] The core library consists of two parts: one part is the function that needs to be called by the Java language, and the other part is the Android core library.

[0180] The application layer and the application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

[0181] The system library may include multiple functional modules, such as surface manager, media library, 3D graphics processing library (such as OpenGL ES), 2D graphics engine (such as SGL), etc.

[0182] The surface manager is used to manage the display subsystem and provide the fusion of 2D and 3D layers for multiple applications.

[0183] The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0184] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0185] A 2D graphics engine is a drawing engine for 2D drawings.

[0186] The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, and sensor driver.

[0187] The method provided in the embodiment of the present application can be implemented by an application program at the application program layer, or by the bottom layer of the operating system, such as the kernel layer, system library and / or application program framework layer. When the above method is implemented based on the bottom layer of the operating system, it can be used across applications.

[0188] See also Fig.14a and Fig.14b , is another schematic diagram of a display interface provided in an embodiment of the present application. Fig.14a 1401 and the second application window 1402 are shown in the figure. The user determines the pattern extraction area 1403 in the first application window 1401 by circling the selection operation.
