Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a dictionary pen. Background Technology

[0002] With the rapid development of optical character recognition technology and embedded translation systems, dictionary pens, as a new type of electronic learning tool, have gradually replaced the traditional button input method for looking up words in electronic dictionaries. Users can quickly scan to look up unfamiliar words, and the word's explanation, definition, and pronunciation are displayed immediately, making the operation convenient and efficient. Furthermore, dictionary pens are typically designed with a pen-like structure, making them lightweight, portable, and easy to hold, greatly enhancing the user experience.

[0003] However, current dictionary pen products still have significant shortcomings, with the core issue concentrated in the illumination system of the scanning imaging. Specifically, existing dictionary pens tend to create areas of excessive brightness (even producing highly reflective spots) and areas of excessive darkness in the captured images. This uneven illumination directly leads to the loss of some text features in the image, reduced contrast, or the generation of interfering noise.

[0004] The aforementioned image quality issues severely interfere with subsequent optical character recognition processes, leading to decreased text recognition accuracy, increased false recognition rates, and ultimately impacting users' word lookup success rates and product reliability. Therefore, an improved dictionary pen design is urgently needed to address the problem of poor illumination uniformity in scanned images, thereby enhancing the accuracy and stability of dictionary pen recognition.

[0013] According to one embodiment of this application, the scanning window is a light-transmitting scanning window, and the light emitted by the supplementary light is transmitted through the scanning window to the text medium to be scanned.

[0014] According to one embodiment of this application, the light intensity of the supplementary light is 130 mcd to 280 mcd.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0027] The following is combined Figures 1-2 This invention describes a dictionary pen.

[0028] The dictionary pen proposed according to the embodiments of this application includes a pen body 1, and the pen body 1 is provided with a scanning window 4; The pen body 1 is equipped with a scanning component, which includes a camera 2 and a fill light 3. The camera 2 is used to capture the text content selected by the scanning window 4, and the fill light 3 is arranged around the outside of the camera 2.

[0029] According to the dictionary pen of this application embodiment, the supplementary light 3 is arranged around the outside of the camera 2, which can provide uniform illumination for the field of view of the camera 2 from 360 degrees. This effectively avoids reflections and light spots caused by side light, greatly improves the uniformity of the captured image, and thus improves image quality and recognition accuracy.

[0030] In traditional scanning devices, light often shines from both sides of the camera 2, which easily generates lateral light on the text surface, causing reflections and light spots. These reflections and light spots severely interfere with the accurate capture of the text image by the camera 2, resulting in areas that are too bright or too dark, affecting the uniformity of the image. However, the dictionary pen of this embodiment effectively avoids this problem by using a supplementary light 3 surrounding the outside of the camera 2. It makes the light received by the text surface more uniform, greatly improving the uniformity of the captured image. Improving image quality is crucial for text recognition. High-quality images provide more accurate information for the recognition algorithm, thereby improving recognition accuracy and providing users with a more reliable and efficient learning assistance experience.

[0031] Understandably, the pen body 1, as the main structure of the dictionary pen, provides stable mounting space and necessary protection for the various internal components. The pen body 1 can be made of high-strength, lightweight materials, such as high-quality plastics or metal alloys, to ensure the dictionary pen is sturdy and durable while minimizing weight for convenient long-term handheld use.

[0032] The scanning window 4 is located at one end of the pen body 1 and is an important window for the dictionary pen to interact with the text medium to be scanned. The scanning window is used to select the text content. In some embodiments, the scanning window has an open structure, which can be a blind hole or a through hole that runs through the front and rear ends of the pen body 1. In some embodiments, the scanning window 4 is provided with a light-transmitting cover, which can be an optical glass cover or a special optical plastic cover. The high light transmittance of the light-transmitting cover can minimize the loss of light during transmission. The light emitted by the supplementary light 3 can pass through the scanning window 4 smoothly to reach the text medium, providing sufficient and uniform illumination for the text. At the same time, the light reflected back from the text surface can also enter the scanning component without obstruction, ensuring that the camera 2 can receive clear and accurate image information.

[0033] Camera 2 is responsible for capturing the text content selected by scanning window 4. Camera 2 can employ a high-resolution image sensor, such as a CMOS (Complementary Metal-Oxide-Semiconductor) or CCD (Charge-Coupled Device) sensor. These sensors offer advantages such as high sensitivity and low noise, enabling them to capture clear and detailed images under various lighting conditions. The lens of camera 2 is carefully designed and optimized with appropriate focal length and aperture to ensure accurate focusing on the text to be scanned and to control the amount of light entering the lens, thereby obtaining a high-quality image.

[0034] According to one embodiment of this application, the emitting surface of the supplementary light 3 faces the same direction as the lens of the camera 2. It is understood that the supplementary light 3, surrounding the outside of the camera 2, provides a uniform illumination base for the camera 2's field of view from a 360-degree angle, while the emitting surface facing the same direction as the lens further ensures that the light is accurately projected onto the target area, avoiding light waste and unnecessary interference. In this way, the light emitted by the supplementary light 3 can directly illuminate the text to be scanned without scattering in other directions, improving light utilization and reducing reflections and interference from the surrounding environment, enabling the camera 2 to receive a cleaner and more accurate text image.

[0035] According to one embodiment of this application, the annular central axis of the fill light 3 coincides with the optical axis of the camera 2. For the fill light 3 arranged in a ring, its annular central axis is a straight line passing through the geometric center of the ring fill light 3 and perpendicular to the plane of the ring. The optical axis of the camera 2 refers to the straight line passing through the center of the lens of the camera 2 and perpendicular to the main plane of the lens. It is the center line of the shooting angle of the camera 2, determining the center position of the image captured by the camera 2 and the main direction of light propagation. When the annular central axis of the fill light 3 coincides with the optical axis of the camera 2, the light emitted by the fill light 3 can be distributed symmetrically and uniformly within the field of view of the camera 2, centered on the optical axis of the camera 2. This design of coinciding the annular central axis of the fill light 3 with the optical axis of the camera 2 in this embodiment of the application effectively avoids the above-mentioned adverse situations. It provides the camera 2 with the most ideal lighting conditions, ensuring uniform lighting on the text surface and reducing adverse phenomena such as reflection, light spots, and uneven lighting. For example, on text surfaces with complex textures or gloss, this uniform lighting ensures that camera 2 captures every detail of the text, improving image clarity and legibility.

[0036] According to one embodiment of this application, the angle between the optical axis of the camera 2 and the end face of the scanning window 4 is 0° to 10°.

[0037] Understandably, when the angle is between 90° and 90°, the light reflection path is relatively stable. After being reflected from the text surface, the light can enter camera 2 relatively smoothly, maximizing the intensity and uniformity of the light entering camera 2. If the angle is too large, the direction of light reflection will change significantly, potentially preventing some light from entering camera 2, thus affecting the brightness and clarity of the image. Within this angle range, it ensures that the light is reflected into camera 2 in a suitable manner, resulting in more stable image quality.

[0038] It should be noted that the angle between the optical axis of camera 2 and the end face of scanning window 4 can be 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 89°, or 90°. In practical applications, it can be adjusted appropriately according to specific scanning requirements and text characteristics.

[0039] It should be noted that the scanning window end face mentioned in this application refers to the plane on which the scanning window is located on the dictionary pen. When the user scans text with the dictionary pen, this end face is directly opposite the text surface and is used to select the text content to be scanned.

[0040] In one embodiment, the angle between the optical axis of the fill light 3 and the end face of the scanning window is 0° to 10°.

[0041] The fill light 3 is used to enhance the surface brightness of the scanned object and improve image contrast in low-light environments. In some possible embodiments, the optical axis of the fill light 3 is parallel to the end face of the scanning window.

[0042] It should be noted that the angle between the optical axis of the supplementary light 3 and the end face of the scanning window can be 0°, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, or 10°. In practical applications, it can be adjusted appropriately according to specific scanning requirements and text characteristics.

[0043] To better illuminate the book, the dictionary pen's scanning window is designed to be angled. To complement this angle, the outer ring light is also designed with a sloping shape, lower in the front and higher in the back. This ensures that the light shines directly onto the text being scanned, rather than being tilted to one side, thus avoiding shadows and reflections and making the captured text clearer.

[0044] In some possible embodiments, the end face of the scanning window is inclined relative to the end face of the hand grip of the pen body 1, and the fill light 3 has a near window light part close to the end face of the scanning window and a far window light part away from the end face of the scanning window, wherein the height of the near window light part is less than the height of the far window light part, so that the angle between the optical axis of the fill light 3 and the end face of the scanning window is 0° to 10°.

[0045] In some possible embodiments, the height change from the near-window light section to the far-window light section is linear.

[0046] According to one embodiment of this application, the distance between the fill light 3 and the camera 2 is L, where L is 2mm to 8mm.

[0047] Understandably, the distance between the fill light 3 and the camera 2 is 2mm to 8mm. This ensures that there is enough space between the fill light 3 and the camera 2 for independent installation and wiring, avoiding mutual interference and ensuring that they work normally. At the same time, it does not make the dictionary pen too large, which meets the design requirements of miniaturization and portability, making it convenient for users to carry and use it.

[0048] It should be noted that the distance between the fill light 3 and the camera 2 is greater than the radius of the camera, to ensure that the fill light 3 does not obstruct the camera 2.

[0049] According to one embodiment of this application, the supplementary light 3 is an LED light ring. An LED light ring is a lighting component consisting of multiple light-emitting diodes arranged in a ring. Light-emitting diodes have many advantages, such as high luminous efficiency, long lifespan, fast response speed, and energy saving and environmental friendliness. By rationally arranging multiple light-emitting diodes, the LED light ring can achieve uniform and stable light output. Compared with traditional lighting methods, the LED light ring can adjust the color and brightness of the light as needed to meet the usage requirements of different scenarios. In the dictionary pen of this application, the LED light ring can provide continuous and uniform illumination for the camera 2, ensuring that high-quality text images can be captured in various environments.

[0050] According to one embodiment of this application, the scanning window 4 is a light-transmitting scanning window 4, and the light emitted by the supplementary light lamp 3 is transmitted through the scanning window 4 to the text medium to be scanned.

[0051] The high light transmittance of the scanning window 4 minimizes light loss during transmission. The light emitted by the supplementary light 3 can pass smoothly through the scanning window 4 to reach the text medium, providing sufficient and uniform illumination for the text.

[0052] According to one embodiment of this application, the luminous intensity of the supplementary light 3 is between 130 mcd and 280 mcd. This provides sufficient illumination for the text, enabling the camera 2 to clearly capture the text image, without wasting energy due to excessive light intensity. If the light intensity is too weak, it may fail to illuminate the text surface, resulting in a blurry image; if the light intensity is too strong, it will not only increase the power consumption of the dictionary pen and shorten battery life, but may also produce excessive reflection on the text surface, affecting image quality.

[0053] According to one embodiment of this application, a main control circuit board is provided inside the pen body 1. The main control circuit board integrates an image processing unit, a translation unit, and a display control unit. The image processing unit is used to receive images captured by the camera 2 and perform optical character recognition; the translation unit is used to translate the recognized text; and the display control unit is used to control the display of the recognition and / or translation results.

[0054] Understandably, the main control circuit board integrates various electronic components and circuits, responsible for coordinating and managing the operation of the dictionary pen's various functional modules to ensure the device functions normally and efficiently. The main control circuit board integrates multiple functional modules such as an image processing unit, a translation unit, and a display control unit. These modules cooperate with each other to achieve the dictionary pen's core functions.

[0055] Image processing unit. This unit is specifically responsible for processing the images captured by camera 2. Its main task is optical character recognition (OCR), which accurately identifies text information from images. It can analyze features such as pixel distribution and color changes in images, converting the text in the image into electronic text format that a computer can understand and process, providing basic data for subsequent functions such as translation.

[0056] The translation unit receives text information recognized by the image processing unit and uses built-in translation algorithms and a vast language database to accurately translate the text. It can quickly and accurately translate text from one language to another according to the user's needs, meeting the user's language conversion needs in learning, communication, and other scenarios. For example, when a user needs to translate an English article, the translation unit can translate it sentence by sentence into Chinese, ensuring the accuracy and fluency of the translation result. Simultaneously, the translation unit also supports multiple translation modes, such as whole-sentence translation and word-by-word translation, to meet the user's language conversion needs in different scenarios.

[0057] The display control unit is responsible for controlling the display of content on the dictionary pen's screen. It receives the results processed by the image processing and translation units, and, according to preset display rules and user commands, clearly displays the recognized text, translation results, and other information on the screen. The display control unit can adjust parameters such as the font, size, and color of the displayed content to suit different users' habits and visual needs. For example, users with poor eyesight can increase the font size; users who prefer a simple style can choose a black-and-white display mode.

[0058] According to one embodiment of this application, a display unit is provided on the pen body 1 for outputting the interpretation and translation of text.

[0059] The display unit can use a high-resolution liquid crystal display (LCD) or an organic light-emitting diode display (OLED), which can provide a clear and vibrant display effect. The display area of ​​the display unit can display complete information simultaneously, making it convenient for users to view.

[0060] The display area of ​​the display unit can simultaneously show complete information for easy viewing. For example, when displaying translation results, it can show an entire sentence or paragraph at once, avoiding frequent page flipping. Simultaneously, the brightness of the display unit automatically adjusts according to ambient light, increasing brightness in bright light to ensure clear visibility and decreasing brightness in low light to reduce eye strain. This automatic brightness adjustment adapts to different usage scenarios, providing a more user-friendly experience. When a user scans text with the dictionary pen, the results processed by the image processing and translation units are quickly displayed on the display unit, allowing the user to access the necessary information promptly and improve learning and work efficiency.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
