With the advancement of technology, traditional paper data has gradually moved towards electronicization. Since electronic data is easy to store and carry, it is also more convenient to search than traditional paper copies. Therefore, in terms of word processing, it has gradually evolved to use electronic devices to record data, so as to provide users with functions such as recording memos and even drawing. For example, it is not necessary to use a traditional notebook when attending a class or taking minutes of a meeting. As long as one carries an electronic device (such as a notebook computer) with the function of an electronic notebook, it can be used to record important notes.

However, for traditional electronic notebook applications, it is necessary to leave the running program screen first, and then open the page of the relevant application program for editing and writing. If the user wants to add notes to the program screen currently being executed, he must first capture the screen picture, and then import the captured picture file into the application program of the electronic notebook for further editing. For users, the whole process is lengthy and disconnected.

Detailed ways

When a traditional electronic device is running an application program, if you want to enable the handwriting function, you usually have to leave the currently running application program and then activate the recording tool to start writing, which is inconvenient to use. The present invention provides a track recording method and an electronic device, which can enter the track recording mode at any time without exiting the currently executing application program. In order to make the content of the present invention clearer, the following specific examples are given as examples in which the present invention can actually be implemented.

FIG. 1A is a block diagram of an electronic device according to an embodiment of the invention. Please refer to FIG. 1A , the electronic device 100 is, for example, a desktop computer, a notebook computer, a tablet computer, a smart phone, etc., which have computing functions, and it at least includes a display unit 110 , a storage unit 120 , a processing unit 130 and a recording module 140 . Wherein, the processing unit 130 is coupled to the display unit 110 , the storage unit 120 , and the recording module 140 .

The display unit 110 is, for example, a cathode ray tube (Cathode Ray Tube, CRT) display, a liquid crystal display (Liquid Crystal Display, LCD), a plasma display (Plasma Display), a touch display (Touch Display) and the like. Wherein, the touch display is, for example, a capacitive screen, a resistive screen, a fluctuating screen, or a screen with a touch operation function after being combined with other components.

The storage unit 120 is, for example, a non-volatile memory (Non-volatile memory, NVM), a dynamic random access memory (Dynamic Random Access Memory, DRAM), or a static random access memory (Static Random Access Memory, SRAM).

The processing unit 130 is, for example, a central processing unit (Central Processing Unit, CPU) or a microprocessor (microprocessor), which is used to execute hardware and firmware in the electronic device 100 and process data in software.

The recording module 140 is, for example, a chip composed of one or more digital logic gates, or a code segment composed of a computer program language. For example, if the recording module 140 is implemented with digital logic gates, the recording module 140 is coupled to the processing unit 130 and is driven by the processing unit 130 to execute. In addition, for implementing the recording module 140 with code segments, the recording module 140 can be stored in the storage unit 120 . The multiple code segments of the recording module 140 will be executed by the processing unit 130 after being installed. These code segments include a plurality of instructions, by which the processing unit 130 executes a plurality of steps of the method for recording an input track. In this embodiment, the electronic device 100 only includes one processing unit 130 , but in other embodiments, the electronic device 100 may also include multiple processing units, and the installed code segments are executed by these processing units.

The recording module 140 may further include multiple modules. For example, FIG. 1B is a block diagram of a recording module according to an embodiment of the present invention. Please refer to FIG. 1B , the recording module 140 mainly includes a state switching module 141 , a layer control module 142 , a receiving module 143 and a storage module 145 , and may further include a merging module 144 , a frame capture module 146 and an operation point tracking module 147 .

The state switching module 141 is used for switching between the use state and the standby state of the recording module 140 . The layer control module 142 is used to control the display of the drawing layer. The receiving module 143 is used for receiving an input track by drawing a layer. The merging module 144 is used for merging the input trajectory and the captured image (for example, the image obtained by capturing the operation screen) into a composite image. The storage module 145 is used for recording the synthesized image into the storage unit 120 . The screen capture module 146 is used to capture the operation screen to obtain a captured picture. The operation point tracking module 147 is used for tracking the movement of the operation point on the display unit 110 . The above operation point is, for example, a cursor, or a touch point formed by touching the display unit 110 with a finger or a stylus. That is, when the display unit 110 receives a signal (such as a trigger signal), the layer control module 142 generates an operation point, and the display range of the drawn layer can be controlled through the control point.

The steps of the method for recording an input track are described above in combination with the electronic device 100 . FIG. 2 is a flowchart of a method for recording an input track according to an embodiment of the invention. In this embodiment, for convenience of description, a touch screen is used as the display unit 110 , but in other embodiments, the display unit 110 can also be a display without touch function.

Referring to FIG. 1A , FIG. 1B and FIG. 2 , in step S205 , when the electronic device 100 starts the operating system, the processing unit 130 automatically enables the recording module 140 so that the recording module 140 enters a standby state.

Next, in step S210, when the display unit 110 of the electronic device 100 displays an operation screen, when the processing unit 130 determines that the recording module 140 is triggered, the recording module 140 is switched from the standby state to the use state through the state switching module 141 . For example, the recording module 140 can be triggered when the electronic device 100 has started any application program, or when the electronic device 100 is displaying a desktop. In addition, if the electronic device 100 has already activated the application program, when the processing unit 130 determines that the recording module 140 is triggered, the processing unit 130 may further suspend the function of the application program being executed by the electronic device 100 to avoid misoperation of the application program.

An example is given below to illustrate the triggering process of the recording module 140 . For example, the trigger area can be set in the display unit 110 , and when the processing unit 130 detects that the trigger area receives a trigger signal when the operation screen is displayed, the state switching module 141 determines that the recording module 140 is triggered. The aforementioned trigger area is, for example, a visible virtual button or a hidden area. For example, a virtual button can be displayed at a designated position on the display unit 110 at any time. Or, in a normal state, the trigger area is hidden but not displayed, and the trigger area will be displayed only when the user moves a finger, stylus or cursor to a designated position on the display unit 110 . When the trigger area receives a trigger signal (for example, the trigger area is pressed), the state switching module 140 switches the recording module 140 from the standby state to the active state.

Next, in step S215 , when the recording module 140 is in use, the drawing layer is displayed by the layer control module 140 . Here, the drawing layer is overlaid on the operation screen. Paint layers can be transparent, semi-transparent, or opaque. Here, the layer control module 140 may directly display the drawing layer on the top of the operation screen, or the layer control module 140 may display the drawing layer in a pull-out manner.

In addition, in order to facilitate the user to draw or write by hand, a grid layer may be further displayed between the drawing layer and the operation screen. For example, FIG. 3 is a schematic diagram of layer relationships according to an embodiment of the present invention. Please refer to Fig. 3, in this embodiment, the uppermost layer is a drawing layer 320 for receiving user's hand drawing or handwriting, and the next layer of drawing layer 320 is a grid layer 330, and the bottom layer is an operation layer 320. Screen 310.

When the recording module 140 is triggered and switched to the use state, the drawing layer 320 is displayed above the operation screen 310 , and the grid layer 330 is displayed between the drawing layer 320 and the operation screen 310 . In this embodiment, the drawing layer 320 is a transparent layer, and the grid layer 330 is a translucent layer. Accordingly, the drawing layer 320 and the grid layer 330 are overlaid on the top of the operation screen 310 , and the user can still clearly see the contents of the bottommost operation screen 310 .

In addition, the above-mentioned operation screen may also be a scrollable screen. In the step of displaying the drawing layer, the layer control module 142 may also extend the drawing layer in the same scrolling direction as the operation screen scrolls in the scrolling direction.

Afterwards, in step S220, the receiving module 143 receives the input track by drawing the layer. For example, when the display unit 110 is a touch screen, after the drawing layer is displayed, the user can use his finger or a stylus to perform a drawing operation on the display unit 110 . Alternatively, when the display unit 110 is a non-touch screen, after displaying the drawing layer, the user can use an input device such as a mouse to control the cursor displayed on the display unit 110 , and then perform drawing operations on the display unit 110 .

Then, in step S225, when the processing unit 130 receives the storage instruction, the storage module 145 stores the input trajectory to form a composite map. In addition, the input track and the background layer can be further combined by the merging module 144 to obtain a composite image. The aforementioned background layer is, for example, a captured image, a white image or a transparent layer. Here, the captured image is obtained by capturing an operation screen. The time point of capturing the picture may be the time point when the decision recording module 140 is triggered, or the time point when the storage instruction is received.

For example, when the drawing layer is displayed, a toolbar table may be displayed above (or in other positions) the drawing layer, and the toolbar table includes various functions. When the storage function in the toolbar table is enabled, a storage command is sent, so that the merging module 144 merges the input trajectory received from the rendering layer 320 with a background layer, so as to obtain a composite image. Afterwards, the composite image can be recorded into the storage unit 120 through the storage module 145 .

In practical application, the first storage button, the second storage button and the third storage button can be set in the function list of the drawing layer. Before the drawing layer is displayed, the screen of the display unit 110 includes the running application program and the status bar (Status Bar). After the drawing layer is displayed, the application's operation screen becomes the background. When the user presses the first save button on the function list of the drawing layer, the recording module 140 can embed the captured picture of the operation screen into the drawing layer as a background. In this way, the user can perform drawing actions on the drawing layer. When the user wants to save or share, the combined result obtained by the user is a composite image of the input track and the captured image. Accordingly, when the executed application program is an electronic map, the recording module 140 can be used to mark the electronic map. In addition, when the executed application program is an electronic file, the recording module 140 can also be used to add important reminders and the like on the electronic file. And when the user presses the specific function button on the function list of the drawing layer again, the above-mentioned background layer will be removed, so that the user can see the operation screen of the original application program again.

When the user presses the second save button on the function list of the drawing layer, the recording module 140 only saves the input track without merging the background layer (the captured picture of the operation screen). For example, the tracing paper function can be performed by the recording module 140 . That is, an action of drawing the bottom operation screen (for example, a specific pattern) on the drawing layer, and then only storing the drawn input track without storing the bottom operation screen.

When the user presses the third save button on the function list of the drawing layer, the recording module 140 will use a white picture (or other default picture) as the background layer, and use the white picture to merge with the input track. That is, similar to note paper or general electronic notebook functionality. For example, when the user suddenly has something important to record while executing the application program, he can trigger the recording module 140 to write on the drawing layer, and then press the third storage button, and the default picture will be used as the background layer to be merged with the input track.

In addition, the above-mentioned captured picture of the operation screen can be obtained by capturing the current operation screen of the electronic device 100 by the screen capture module 146 when the determination recording module 140 is triggered. Alternatively, the screen capture module 146 can capture the current operation screen of the electronic device 100 to obtain the captured picture when the storage command is received.

For example, in the case that the operation screen is a static screen, it is set to capture the current operation screen by the screen capture module 146 when it is determined that the recording module 140 is triggered. In addition, when the operation screen is a dynamic screen (for example, a movie is being played), it is set to capture the current operation screen by the screen capture module 146 only when a storage command is received. That is to say, the user can record the required data synchronously when the video is played. However, the above is just an example, and the settings can be made according to the actual application requirements, and are not limited to this.

An example is given below to illustrate the process of controlling the drawing layer. 4A-4D are schematic diagrams of fast handwriting on an electronic device according to an embodiment of the present invention. Referring to FIGS. 4A-4D , the electronic device 100 is a smart phone, the display unit 110 is a touch screen, and a stylus 410 is used for touch operations.

In this embodiment, the display unit 110 of the electronic device 100 is in the case of displaying an operation screen (for example, in a state not in the power saving mode), and is provided with a trigger area 420 . As shown in FIG. 4A, when the user places the stylus 410 in the trigger area 420, the recording module 140 is switched to the use state, and the layer control module 142 is in the position where the trigger signal is received on the display unit 110 (i.e. , the stylus 410 lands on the position of the display unit 110 ) to generate an operation point 430 . Next, the movement of the operation point 430 is detected by the operation point tracking module 147 .

As the operating point tracking module 147 detects that the moving distance of the operating point 430 increases in the specific direction 41 , the layer control module 142 gradually increases the display range of the drawing layer 400 (the dot range shown in FIG. 4B ). And when the operation point 430 moves to a specific direction 41 and the distance is greater than the preset distance, and the operation point 430 is released (that is, the stylus 410 leaves the display unit 110), the layer control module 142 displays all the drawing layers 400 , so that the rendering layer 400 completely covers the top of the operation screen.

In this embodiment, the specific direction 41 is set from left to right, and the default distance is set to be half of the width w of the display unit 110 . The distance that the operating point 430 moves from the position shown in FIG. 4A to the position shown in FIG. 4B is d. Assuming that when the operating point 430 is moved to the position shown in FIG. 4B and it is detected that the operating point 430 is released, since the distance d is greater than w/2, the layer control module 142 will display all the drawing layers 400 on the display unit 110 middle. That is to say, after the user moves the stylus 410 from the position shown in FIG. 4A to the position shown in FIG. 4B, and then moves the stylus 410 away from the display unit 110, as shown in FIG. Overlaid on the top of the operation screen.

On the other hand, when the operation point 430 moves to the specific direction 41 for a distance not greater than the preset distance and the operation point is released, the drawing layer 400 will cancel the display of the drawing layer 400 .

Next, in FIG. 4C , the user uses the stylus 410 to draw on the drawing layer 400 to generate an input track 440 .

In addition, the method of turning off the rendering layer 400 is shown in FIG. 4D . The drawing layer 400 can be closed by pushing the drawing layer 400 in a retracting direction 42 opposite to the specific direction 41 . For example, after pulling out the entire drawing layer 400 in a specific direction 41 , the trigger area 420 will disappear, and a closed area 450 will appear (refer to FIG. 4D ). When the drawing layer 400 is displayed, when it is detected that the stylus 410 touches the closed area 4250, an operation point 430' is generated, and the operation point is released after moving the stylus 410 to the retracting direction 42 for a specified distance 430', the layer control module 1402 can cancel the display of the drawing layer 400. However, FIG. 4A-FIG. 4D are only examples for illustration, and the above operations can be appropriately adjusted according to the actual situation.

In addition, if the electronic device 100 is a device with a call function, the recording module 140 can also be suspended when receiving an incoming call, and the recording module 140 can be activated after the incoming call ends. Another example will be given below.

FIG. 5 is a block diagram of an electronic device with a call function according to an embodiment of the invention. In this embodiment, components having the same functions as those of the above-mentioned electronic device 100 are marked with the same numbers, and related descriptions are omitted. Please refer to FIG. 5 , the electronic device 500 further includes a voice communication module 510 . The voice communication module 510 is used for sending and receiving voice communication signals, and generates an incoming call notification message when receiving an incoming call, and generates an incoming call end message when the incoming call ends.

When the recording module 140 receives an incoming call notification message from the voice communication module 510, the input track is temporarily stored by the storage module 145, and the recording module 140 is switched from the use state to the standby state by the state switching module 141, so that the layer control module 142 temporarily Cancel the display of the drawing layer, and start the call interface through the voice communication module 510 .

And, when the recording module 140 receives the incoming call end message from the voice communication module 510, the recording module 140 is switched from the standby state to the use state through the state switching module 141, so that the layer control module 142 re-displays the drawing layer, and through the voice The communication module 510 closes the call interface. Here, the previously staged input track is included in the redisplayed paint layer.

That is to say, when the user is performing a drawing action on the drawing layer, if a call happens to come in, the display of the drawing layer can be temporarily canceled, and the screen of the display unit 110 can be switched to the call interface. After the incoming call is over, the screen of the display unit 110 is automatically switched back to the drawing layer including the previously input track.

To sum up, in the above embodiments, the user can trigger the recording module in any operation screen, so as to display the drawing layer to perform input actions. According to this, when the user urgently needs to write notes immediately, the recording module can be triggered at any time to display the drawing layer and then write immediately. There is no need to leave the running application before opening the note program, and there is no need to capture the operation screen before importing. Import other tools for post-production. It is more convenient, faster and more humanized in use.

Although the present invention has been disclosed as above with the embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the claims.
