DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] Figure 2 This is a flow chart of the display method provided by the present invention, such as Figure 2 As shown, the method includes the following: Step 210 , in response to a user's sliding operation of scanning content using the dictionary pen, stitching together the scanned image frames recorded by the dictionary pen during the content scanning process to obtain an overall scanned image; In this application, the dictionary pen integrates optical character recognition technology and an embedded translation system. Designed in the shape of a pen, it is easy for users to hold and operate. It uses a camera to scan text or images on media (such as paper or screens), quickly identifying and processing the content, providing users with a more convenient search and learning experience.

[0029] In an optional embodiment, the screen of the dictionary pen adopts a full-screen design, that is, the screen occupies most or even almost all of the front area of ​​the dictionary pen. This design enables the screen to provide a larger display area, presenting a wider and more complete visual content to the user.

[0030] In the present invention, a user uses a dictionary pen to scan information such as text, pictures, etc. on a medium. During the scanning process, the user holds the dictionary pen and performs a sliding operation on the medium.

[0031] This sliding operation typically involves a uniform movement from left to right or from top to bottom, for example. This allows the Dictionary Pen's camera to continuously capture content along the scanning path, thereby completing a complete scan of the entire text or image. During the sliding operation, the Dictionary Pen's camera continuously captures content along the scanning path, generating individual scanned image frames.

[0032] In this invention, a scanned image frame is a series of individual images captured by the dictionary pen's camera at a specific frame rate, such as 30 frames per second, during the content scanning process. Each image frame represents the content at a specific moment and location along the scanning path. These scanned image frames serve as the basis for subsequent stitching processing.

[0033] In this invention, multiple scanned image frames are seamlessly connected using an image processing algorithm based on their spatial order and positional relationship during the scanning process. Since the scanned image frames may have some overlapping areas, the stitching algorithm needs to identify and correct these overlapping areas to produce a complete and coherent scanned image.

[0034] The process of seamlessly connecting multiple scanned image frames using image processing algorithms, based on their spatial order and positional relationship during the scanning process. Since scanned image frames may have overlapping areas, the stitching algorithm needs to identify and correct these overlapping areas to produce a complete and coherent scanned image.

[0035] The overall scan image encompasses the content of all scanned image frames captured during a scan. This provides users with more comprehensive visual information, allowing them to intuitively see the entire scanned content, making it easier to view, edit, and query it later.

[0036] Step 220, displaying an observation window interface and the overall scan image on the display screen of the dictionary pen; wherein, the observation window interface includes the latest scan image frame in the overall scan image, and the latest scan image frame is the scan image frame most recently entered by the dictionary pen.

[0037] In the present invention, the display screen of the dictionary pen can be a full screen, occupying most of the area on the front of the dictionary pen. This design brings a wider visual space for the user, allowing more content to be presented to the user at the same time.

[0038] In the present invention, the camera of the dictionary pen continuously captures a series of image frames during the scanning process, and the latest scanned image frame is the most recently captured one of these image frames. It represents the latest content acquired at the current moment of the scanning operation and is a real-time record of the scanning process.

[0039] As the dictionary pen slides, the camera continuously captures new scanned image frames. These new scanned image frames are added to the overall scanned image in real time through frame stitching, ensuring that the overall scanned image always contains the latest scanned image frames. When a new scanned image frame is generated, the overall scanned image is updated accordingly to reflect the latest scanned content.

[0040] In the present invention, a display window interface is displayed on the screen, focusing on the most recently scanned image frame. Like a window, the display window interface provides a focused perspective for the user, enabling them to clearly see the content at the current scanning location. The display window interface dynamically updates as the dictionary pen is slid, always displaying the most recently entered scanned image frame.

[0041] The captured image gradually expands as the viewing window moves, similar to the visual effect of unfolding a scroll. This design not only enhances visual appeal but also helps users intuitively see the scanning progress.

[0042] Figure 3 This is one of the display schematic diagrams provided by the present invention, such as Figure 3 As shown, the display screen 10 of the dictionary pen displays the overall scan image and the observation window interface 21. As the tip of the dictionary pen slides, the latest scan image frame taken by the dictionary pen keeps changing, and the content displayed in the observation window interface is also dynamically updated.

[0043] At the same time, the viewing window slides along the length of the screen from the pen tip to the end, gradually displaying the real-time captured content on the screen, creating a dynamic visual effect similar to the unfolding of a scroll. This design not only provides a comprehensive display of the scanned content, but also enhances the user's intuitive experience and control over the scanning process.

[0044] In this invention, by responding to the user's sliding operation, the scanned image frames are spliced ​​into a whole scanned image in real time, and the whole image and the observation window interface containing the latest scanned image frame are simultaneously displayed on the display screen. This allows the user to view the scanned content immediately, comprehensively, and in a focused manner during the scanning process, and to promptly grasp the scanning progress and details, ensuring the accuracy and completeness of the scan, greatly improving the user experience and scanning efficiency. Without providing a physical observation window, this invention achieves an observation effect similar to or even better than a physical observation window through the combination of the observation window interface and the whole scanned image, making it possible for dictionary pens to be equipped with larger display screens.

[0045] Optionally, the method further includes: During the sliding operation of the user using the dictionary pen to scan the content, the observation window interface moves on the display screen in the direction from the tip to the tail of the dictionary pen along with the sliding operation.

[0046] In the present invention, when the user performs a sliding operation of scanning content with the dictionary pen, that is, when the user holds the dictionary pen and moves it on the medium to perform a scanning operation, the movement of the observation window interface will be triggered.

[0047] The viewing window interface moves on the display screen in the direction from the tip to the end of the dictionary pen. This means that as the user slides the pen tip, the viewing window interface slides from the side of the display screen close to the pen tip to the end of the pen.

[0048] The sliding movement of the viewing window enhances the dynamic visual effect, allowing users to intuitively see the scanned content unfolding, just like a scroll painting. The movement of the viewing window interface is synchronized with the user's sliding operation, ensuring that users can see the latest scan content in real time during the scanning process, providing instant feedback.

[0049] In the present invention, by sliding the observation window interface, the user can follow the scanning progress more naturally, reducing visual jumps and discontinuities, and improving the overall user experience.

[0050] Optionally, the method further includes: In response to a user triggering a content scan, obtaining the latest scanned image frame recorded by the dictionary pen at the current moment; The observation window interface is displayed at a first display screen position of the display screen, the observation window interface including the latest scanned image frame, and the first display screen position is a display screen position on the display screen close to the pen tip of the dictionary pen.

[0051] In the present invention, the user triggering the content scanning operation specifically refers to a dedicated scanning start button configured on the side or top of the dictionary pen. When the user starts scanning, he only needs to press this button, and the dictionary pen will start the camera and start recording the scanned image frame.

[0052] If the dictionary pen is equipped with a touch screen, the user can trigger content scanning by performing specific gestures on the touch screen, such as double-clicking, long pressing, or swiping inward from the edge of the screen.

[0053] If the dictionary pen has voice recognition function, the user can trigger the content scanning operation by saying a preset voice command, such as "start scanning".

[0054] Once triggered, the Dictionary Pen's camera begins capturing content along the scan path at a specific frame rate. The triggering moment is recorded as the scan start time, and subsequent scanned image frames are time-sequenced and processed based on this time point. This marking maintains the correct sequence when stitching images, ensuring that the viewing window displays the scanned content from the correct starting point.

[0055] In the present invention, the first display screen position refers to the end of the display screen near the tip of the dictionary pen, which is the position visually closest to the pen tip when the user is scanning. The selection of the first display screen position is consistent with the user's natural visual habits, because the user's line of sight is usually focused near the pen tip when scanning.

[0056] Figure 4 The second display diagram provided by the present invention is as follows: Figure 4 As shown, the entire scan image is displayed on the display screen 10 of the dictionary pen, as well as an observation window interface 21. As the scanning action starts, the scanning window on the full screen is activated at one end close to the pen tip. The scanning window displays the camera shooting content in real time, that is, displays the latest scanned image frame.

[0057] The viewing window is located on the primary display, focusing on the latest scanned image frame. This design ensures that users can immediately see the scanned content at the position of the pen tip when they start scanning, providing instant visual feedback.

[0058] The observation window shows the latest scanned image frame recorded by the dictionary pen, that is, the image captured by the camera at the current moment. This allows users to see the real-time results of the scanning operation, enhancing the interactivity and intuitiveness of the scanning process.

[0059] In the present invention, the observation window interface is set at a display screen position close to the pen tip, which is consistent with the user's natural line of sight during the scanning process, so that the user can view the scanned content without additionally adjusting the line of sight focus.

[0060] By displaying the latest scanned image frame in the viewing window, users can monitor the scanning results in real time to ensure the accuracy and completeness of the scanned content. This instant feedback helps users to promptly identify and correct errors or omissions in the scanning process.

[0061] Optionally, the method further includes: When the display observation window interface reaches the second display screen position of the display screen, clearing the entire scan image displayed on the display screen and adjusting the display observation window interface to the first display screen position; The first display screen position is a display screen position close to the tip of the dictionary pen in the display screen, and the second display screen position is a display screen position close to the tail of the dictionary pen in the display screen.

[0062] In the present invention, the first display screen is located close to the tip of the dictionary pen and is the area that the user visually focuses on the most when scanning.

[0063] The second display screen is located near the end of the dictionary pen, usually at the other end of the display screen opposite to the first display screen.

[0064] In the present invention, when the display observation window interface reaches the second display screen position of the display screen, it means that the current scanning operation has occupied the entire display area of ​​the screen. At this time, the system needs to take measures to ensure that the subsequent scan content can continue to be clearly displayed.

[0065] Therefore, when the viewing window reaches the second screen position of the display, the entire scan image displayed on the display is cleared to make room for the new scan content, avoid overcrowding the screen content of the display, and ensure that the user can clearly see the latest scan information.

[0066] While cleaning up the entire scanned image, the dictionary pen adjusts the viewing window interface from the second display screen back to the first display screen. This places the viewing window interface closer to the pen tip visually, preparing for a new round of scanning operations.

[0067] In this invention, the system effectively manages screen space by clearing the entire scanned image when the viewing window reaches the second display screen. This prevents scanned content from accumulating unchecked on the screen, ensuring a clean and readable screen. Repositioning the viewing window to the first display screen ensures a continuous scanning process.

[0068] Optionally, after the steps of clearing the entire scan image displayed on the display screen and adjusting the display observation window interface to the position of the first display screen, the method further includes: In response to the user continuing to scan the content through the dictionary pen, the scanned image frames recorded after cleaning the overall scanned image are spliced ​​together to obtain an updated overall scanned image; The observation window interface and the updated overall scan image are displayed on the display screen of the dictionary pen.

[0069] In the present invention, after clearing the entire scan image on the display screen and adjusting the viewing window interface to the first display screen position, the user can continue to use the dictionary pen to scan the content. The system will respond to the user's sliding operation again and start a new scanning process.

[0070] In the new scanning process, the dictionary pen's camera continues to record new scanned image frames. The system stitches these new image frames together to form an updated overall scanned image.

[0071] The updated overall scan image and the observation window interface (including the latest scan image frame) will be displayed on the display again. The observation window interface continues to start from the first display position and move to the second display position as the scanning operation progresses.

[0072] In this invention, by reassembling new scanned image frames and updating the displayed content, the system dynamically reflects the user's latest scanning operations, ensuring that the user always sees the current scan results. This design eliminates the need for manual intervention to clear the screen or reset the viewing window during extended scanning sessions, improving the overall user experience and making scanning operations smoother and more efficient. It also ensures that after clearing and resetting the screen, the user can seamlessly resume scanning, maintaining the continuity of the scanning process.

[0073] Optionally, the method further includes: When the display observation window interface reaches a second display screen position of the display screen, fixing the display observation window interface at the second display screen position; the second display screen position is a display screen position on the display screen close to the end of the dictionary pen; When the display observation window interface is fixed at the second display screen position and the dictionary pen continues to record scanned image frames, the scanned image frame with the earliest recording time in the overall scanned image is deleted.

[0074] In the present invention, when the display observation window interface reaches the second display screen position of the display screen, it means that the current scanning operation has occupied the entire display area of ​​the screen. At this time, the system needs to take measures to ensure that the subsequent scan content can continue to be clearly displayed.

[0075] After the viewing window reaches the second display screen position, it is fixed there and no longer moves with the scanning operation. While the viewing window is fixed, the dictionary pen's camera continues to capture new scanned image frames. To make room and keep the overall scan image up to date, the system deletes the oldest scanned image frame.

[0076] Therefore, at this time, the observation window is always located on the side of the screen close to the tail end of the pen, and no longer moves toward the tail end of the pen as the scanning operation continues.

[0077] The entire scanned image appears on the display screen like a conveyor belt. The content near the tip of the pen, representing the earliest scanned image frames, gradually disappears, while the content near the end of the pen, representing the most recent scanned image frames, continues to display as the pen tip slides.

[0078] In this invention, by continuously deleting the oldest image frames, the system effectively manages screen space, ensuring that the screen does not become crowded or difficult to view due to excessive content. This dynamic space management allows users to continuously view new scans on the same screen without having to manually clear the screen.

[0079] Optionally, after the step of displaying the observation window interface and the overall scanned image on the display screen of the dictionary pen, the method further comprises: When detecting that the user lifts up the dictionary pen, clearing the entire scan image displayed on the display screen and adjusting the display observation window interface to the first display screen position; In response to a user triggering an operation of content scanning, the overall scan image is displayed on the display screen, and the observation window interface is displayed at the first display screen position.

[0080] In the present invention, the user lifts the dictionary pen usually to change lines during the scanning process. The dictionary pen detects the user's action of lifting the dictionary pen through a built-in sensor, such as a pressure sensor or an optical sensor, and determines that the user may need to change lines.

[0081] After detecting the lift, the system clears the entire scan image on the display to make room for the new scan. At the same time, the system moves the viewing window interface back to the first display position, closer to the pen tip, so that the user can start from a clear starting point when the new scan line begins.

[0082] When the user presses the dictionary pen again to scan again, the dictionary pen will display the observation window interface on the first display screen, showing the latest scanned image frame, and will also display the overall scanned image frame. At the beginning of the scan, the overall scanned image frame may only include the latest scanned image frame in the observation window interface. As the content is scanned by sliding, subsequent scanned image frames will be spliced ​​together to continuously enrich the content of the overall scanned image frame.

[0083] In this invention, when the user needs to wrap a line, lifting the dictionary pen triggers the system to clear the screen and reset the viewing window interface. This allows the user to continue scanning from a clear starting point when a new scan line begins, ensuring the neatness and readability of the scanned content, while also improving scanning efficiency and user experience.
