[0050] Please pay attention to Figure 6 A control system for a digital magnifying glass is used to manage functional modules such as image acquisition, AI recognition, voice broadcasting, network communication, power control, and user interaction. The control system is installed and runs on the control motherboard 4, providing a basic software platform for the entire digital magnifying glass, including:
[0051] As the central computing and control core of the system, it executes the instruction flow of the operating system and coordinates the data interaction and control logic between various hardware modules (such as image acquisition module, communication module, audio output module, etc.). The processing unit includes but is not limited to embedded microprocessors, single-chip microcomputers (MCUs), digital signal processors (DSPs), or artificial intelligence acceleration chips (such as NPUs), and has the ability to run AI models;
[0052] A communication module that connects to the central processing unit, provides 4G and Wi-Fi network access, and supports data synchronization and online updates;
[0053] An audio output module connected to the central processing unit, used to convert the recognition results into voice information and broadcast it to the user;
[0054] The central processing unit (CPU) has a built-in or external image signal processor (ISP) for receiving and initially processing image data captured by the HD camera. The HD camera connects to the CPU via a MIPI CSI-2 interface, which is managed by a dedicated controller within the CPU to ensure efficient and stable data transmission. The ISP is responsible for performing necessary image preprocessing tasks, including but not limited to noise reduction and color space conversion, to provide high-quality input images for subsequent AI recognition algorithms.
[0055] The central processing unit can access the cloud service through the communication module. The cloud service includes one or more AI engine packages designed to perform image recognition tasks based on deep learning and communicate with users.
[0056] The AI engine includes: an image preprocessing unit: which performs preprocessing operations such as enhancement and cropping on the input image; an object recognition unit: which uses a convolutional neural network model to identify target objects in the image; and a result interpretation unit: which generates easy-to-understand text descriptions and passes them to the speech engine for conversion into speech.
[0057] Please pay attention to Figure 7 A method for implementing a digital magnifying glass comprises the following steps:
[0058] When the user presses the power button 9, the processing unit 4 starts loading the operating system and initializing various drivers and services. The operating system detects and configures key components such as the image acquisition module, communication module, and audio output module to ensure they are in a ready state.
[0059] When the user points the digital magnifying glass at the target object and adjusts the image size by rotating the lens zoom and pressing the roller 10, the scanning operation is triggered by pressing the lens zoom and pressing the roller 10. At this time, high-definition image data of the target object is captured, and pressing the dialogue start button 11 can start the dialogue with the AI.
[0060] The captured raw image data first passes through the image preprocessing unit for operations such as enhancement and cropping. For example, if the ambient light is low, the image preprocessing unit automatically increases the brightness; if the image is noisy, it performs noise reduction. These preprocessing steps ensure that the image quality is suitable for the subsequent AI recognition process.
[0061] Processing unit 4 calls the AI engine to analyze the preprocessed image. Using deep learning algorithms such as convolutional neural networks (CNNs), the AI engine can identify the target object in the image and generate an easy-to-understand text description. For example, when the AI engine identifies a cat, it will generate a description such as "This is a cat."
[0062] The generated text description is passed to a text-to-speech (TTS) engine, which converts it into voice information and plays it to the user through an audio output module. Simultaneously, the text description and related information are also displayed on a display screen 2 for the user to view.
[0063] If the device is connected to the internet (via 4G or Wi-Fi), the communication module can upload recognition results to the cloud server, allowing parents or teachers to remotely check their children's learning progress. At the same time, the latest AI models or encyclopedia knowledge base updates can also be downloaded from the cloud, ensuring the system's continuous evolution.
[0064] Through 4G / Wi-Fi connection, the system can regularly check whether new software versions or AI models are available and prompt users to update. This not only improves system security, but also enhances recognition accuracy and user experience.
[0065] The circuit board also integrates a power management module, which monitors the battery status in real time, reminds users to charge in time, and adjusts system performance according to the power status to extend the usage time.
[0066] In summary, the present invention facilitates operation for users of different ages by providing physical buttons, a zoom lens and a push-button wheel, and a dialogue start button. Through an AI engine package, deep learning algorithms are used to analyze captured images in real time, automatically identifying target objects and generating easy-to-understand text descriptions. This not only improves user convenience but also greatly enhances the fun of learning and exploration. The device is equipped with an audio output module that can convert recognition results into voice broadcasts for the user, making it particularly suitable for children or the visually impaired. Furthermore, the recognition results and related information can be intuitively displayed on the display screen, providing a richer user experience.
