[0043] This embodiment provides a camera device. Figure 1 This is a structural block diagram of the camera device in this embodiment, as shown below. Figure 1 As shown, the camera device includes a lens, a base, at least two connectors, a pull-up circuit module, an image sensing module, and an image processing module; the lens is connected to the base; the first connecting part of the connector is connected to the base, the second connecting part of the connector is connected to the image sensing module and grounded, and the middle part of the connector is connected to the input / output interface of the image sensing module; the output terminal of the pull-up circuit module is connected to the input / output interface of the image sensing module, and the number of output terminals and the number of input / output interfaces of the pull-up circuit module are the same as the number of connectors.

[0044] The camera device can be equipped with replaceable lenses, each matching a different base. The connectors can be metallic or non-metallic. The first and second connecting parts of the connector correspond to the areas at both ends of the connector, and the middle part is the area between the first and second connecting parts. The number and / or type of connectors between the base of different lenses and the image sensor vary. Taking n connectors as an example, 2^n different lenses can be identified through different combinations of connectors; n is greater than or equal to 2.

[0045] Connector for securing the base and image sensing module.

[0046] The connectors can be selected from components such as snap-fits, threads, bolts, and inserts that connect the base and the image sensing module together. Optionally, corresponding number and positional positioning holes are provided in the base and the image sensing module, and the connectors pass through the positioning holes in the base and the positioning holes in the image sensing module in sequence to fix the base and the image sensing module together.

[0047] The pull-up circuit module is used to output independent level signals based on each of the aforementioned output terminals.

[0048] The pull-up circuit module includes at least a pull-up circuit consisting of a pull-up resistor and a power supply. The pull-up circuit module provides at least two default, independent high-level signals. The pull-up circuit module can share the same power supply as the image sensing module, or it can use an external power supply. Optionally, in the pull-up circuit module, one end of the pull-up resistor is connected to the power supply, and the other end is grounded. A level signal can be output from the pull-up resistor to the input / output interface of the image sensing module through the output terminal of the pull-up circuit module.

[0049] The image sensing module is used to acquire and transmit level signals to the image processing module.

[0050] In this design, since the middle part of the connector connects to the input / output interface of the image sensing module, and the second connecting part connects to the image sensing module and is grounded, when the connector is metal, the input / output interface of the image sensing module is grounded through the connector, and the level signal input to the input / output interface is pulled low, meaning the image sensing module acquires a low-level signal. When the connector is non-metallic, the level signal input to the input / output interface is not pulled low, meaning the image sensing module acquires a high-level signal. Optionally, the level signal acquired by the image sensing module can be transmitted to the image processing module via bus communication protocols such as I2C (Inter-Integrated Circuit) or SPI (Serial Peripheral Interface). Alternatively, it can be remotely transmitted via communication networks such as Ethernet, Wi-Fi (mobile hotspot), or 5G (fifth-generation mobile communication technology). Alternatively, the level signal can be stored in a storage medium and then actively read by the image processing module to realize the level signal.

[0051] The image processing module is used to generate lens configuration parameters based on the level signal.

[0052] The lens configuration parameters are used to adjust the lens's shooting performance and / or to adjust the image processing parameters obtained from the lens. Optionally, the configuration parameters include one or more of the following: exposure parameters, gain parameters, white balance parameters, and distortion correction parameters. Optionally, different lens types can be identified based on different combinations of received level signals, and configuration parameters applicable to the current lens type can be obtained.

[0053] The camera device in this embodiment connects an image sensing module and a pull-up circuit module, and fixes the base to the image sensing module via connectors. It can change the output level signal of the pull-up circuit module based on different connectors, resulting in different input / output signal levels when the image sensor contacts different connectors. Without relying on the internal electrical structure of the lens, it identifies configuration parameters matching the current lens by collecting the level signals corresponding to multiple connectors, thus solving the problem that the camera device cannot adaptively generate a suitable lens solution when the lens lacks internal electrical properties.

[0054] In one embodiment, the image sensing module includes a signal acquisition unit and a first superposition unit; wherein, the signal acquisition unit is used to acquire level signals based on the input / output interface; the first superposition unit is used to superimpose the acquired level signals onto the blanking area of ​​the image frame captured by the lens, and transmit the image frame to the image processing module.

[0055] The signal lines in the signal acquisition unit are connected to both the output terminal of the pull-up circuit module and the middle part of the connector via input / output interfaces. Optionally, the signal acquisition unit may also include circuitry for signal shaping and / or circuitry to enhance noise immunity, ensuring clear signal edges and preventing misreading. Furthermore, the signal acquisition unit can also be used to acquire light signals transmitted through the lens.

[0056] The blanking region of an image frame refers to the time period during video signal transmission when no image content is displayed on the screen. The blanking region includes horizontal and vertical blanking regions. The horizontal blanking region occurs at the end of each line of image scanning and before the start of the next line; it does not carry image information. The vertical blanking region occurs after the entire frame scan is completed and before the electron beam is repositioned to the top of the screen to begin a new frame; it also does not carry image information. Optionally, a level signal can be superimposed onto the horizontal and / or vertical blanking regions of the image frames captured by the lens. Optionally, the first superposition unit is used to obtain the position of the effective pixel area and the position of the blanking region in the image frame based on the frame synchronization signal; and superimpose the acquired level signal into the blanking region. The level signal can be superimposed into the blanking regions of one or more image frames.

[0057] Furthermore, the camera device includes a video data bus, with its two ends connected to the first overlay unit and the image processing module in the image sensing module, respectively. The video data bus can employ interface schemes such as MIPI (Mobile Industry Processor Interface) or LVDS (Low-Voltage Differential Signaling) to support high-speed data transmission. Optionally, the first overlay unit transmits image frames with superimposed level signals in the blanking region to the image processing module via the video data bus.

[0058] In this embodiment, the image sensing module includes a signal acquisition unit and a first overlay unit. While transmitting image frames, it can synchronously transmit level signals without requiring a separate signal transmission channel. This simplifies the hardware design of the camera device, improves communication efficiency, and allows the image processing module to quickly generate configuration parameters suitable for the current lens based on the level signals.

[0059] In one embodiment, the image sensing module includes a signal acquisition unit and a second overlay unit; wherein the signal acquisition unit is used to acquire level signals based on the input / output interface; and the second overlay unit is used to overlay the level signals and the identification information of the image sensing module, and transmit the overlaid data to the image processing module.

[0060] The identification information of the image sensing module includes features to distinguish different image sensors. Optionally, the second overlay unit generates a parameter field representing the level signal, adding this parameter field to the identification information of the image sensing module to obtain the fused data. The identification information of the image sensing module can be its ID.

[0061] Furthermore, the camera device includes a control bus, with its two ends connected to the second overlay unit and the image processing module in the image sensing module, respectively. The control bus can utilize common communication protocols such as I2C or SP for data interaction. Optionally, the second overlay unit transmits the overlaid level signal and the identification information of the image sensing module to the image processing module via the control bus.

[0062] In this embodiment, the signal acquisition unit and the first overlay unit within the image sensing module transmit the identification information of the image sensing module and the level signal simultaneously. This eliminates the need for an additional independent signal transmission channel, allowing the image processing module to quickly generate configuration parameters that conform to the current lens based on the level signal.

[0063] In one embodiment, the configuration parameters include image configuration parameters and sensing configuration parameters, and the image processing module includes: an identification unit and a configuration unit; wherein, the identification unit is used to acquire the image configuration parameters and sensing configuration parameters corresponding to the level signal; the configuration unit is used to process the image frames captured by the lens based on the image configuration parameters, and configure the image sensing module based on the sensing configuration parameters.

[0064] The image configuration parameters indicate the parameters used during image frame preprocessing. Optionally, the image configuration parameters may include at least one or more of the following: automatic exposure parameters, gain parameters, white balance parameters, and distortion correction parameters. The sensor configuration parameters indicate the parameters used by the sensor to process the signal acquired by the lens. Optionally, the sensor configuration parameters may include at least one or more of the following: analog gain parameters, digital gain parameters, and exposure parameters.

[0065] Optionally, the camera device also includes a storage module connected to the recognition unit in the image processing module; wherein, the storage module is used to store the mapping relationship between the level signal and the configuration parameters; the recognition unit is used to read the mapping relationship stored in the storage module and obtain the image configuration parameters and sensing configuration parameters corresponding to the level signal according to the mapping relationship.

[0066] Optionally, the storage module stores image configuration parameters and sensor configuration parameters corresponding to different combinations of level signals. Based on the received combinations of level signals, the recognition unit searches the storage module to obtain the required image configuration parameters and sensor configuration parameters.

[0067] In this embodiment, by acquiring and configuring the image configuration parameters and sensor configuration parameters corresponding to the level signals, the advantages of the current lens can be maximized and its inherent shortcomings can be compensated for, thereby improving the quality of the final image.

[0068] In related technologies, to differentiate between different lenses, manufacturers set up different interfaces with electrical properties for different lenses, typically using independent built-in chips or independent terminals to distinguish lenses. However, the fixed-focus lenses or fisheye lenses currently used in the security industry are generally mounted on a lens mount, which is connected to the image sensor's circuit board via screws or clips, without any electrical connection. This leads to the problem that the camera device cannot adaptively generate a suitable lens solution when the lens lacks internal electrical properties. Based on this, in one embodiment, Figure 2 A schematic diagram of lens installation is provided, such as... Figure 2 As shown, the lens is mounted on a base, which is fixed to the image sensor via metallized or non-metallized connectors. Figure 2Four connectors are shown in the diagram. It's understandable that the number of connectors can be modified according to requirements. By designing different combinations of connectors, different lenses can be identified, and corresponding configuration parameters, i.e., the adapted lens solution, can be obtained. The connectors can be screws and / or clips. The image sensor in this embodiment is the image sensing module described in the previous embodiment.

[0069] Figure 2 Each connector in the system passes sequentially through a through-hole in the base and a through-hole in the image sensor to securely connect the base and the image sensor. Specifically, the first connecting portion of the connector connects to the lens base; the middle portion of the connector contacts the top surface of the image sensor, with the contact area containing the image sensor's I / O interface; and the second connecting portion of the connector contacts the bottom surface of the image sensor and is grounded. The image sensor's I / O interface is the input / output interface described in the above embodiment.

[0070] Figure 3 A schematic diagram of the connection between an image sensor and a pull-up circuit module is provided, such as... Figure 3 As shown, with n I / O interfaces, the pull-up circuit module is configured with n pull-up circuits, and correspondingly, n connectors can be configured. Each pull-up circuit outputs n level signals, including: individual pull-up signal 1, individual pull-up signal 2, ..., individual pull-up signal n. If a metal connector is connected to the I / O interface of the image sensor module, the signal input to the image sensor is pulled low because the second connection part of the connector is grounded; if a non-metallic connector is connected to the I / O interface of the image sensor module, the signal input to the image sensor remains high. Through different combinational logics, 2^n different lens parameters can be identified, where n is greater than or equal to 2.

[0071] Figure 4 A schematic diagram of signal transmission of a camera device is provided, such as... Figure 4 As shown, the lens transmits lens information to the image sensor, which includes at least the light signal acquired by the lens. The base and the image sensor are connected by at least two connectors, allowing the image sensor to receive different combinations of electrical level signals when different lenses are connected. After acquiring the electrical level signals, the image sensor superimposes the signals onto the blanking region of the image frame and sends the signals to the image processing module via interfaces such as MIPI or IVDS. Figure 5 A schematic diagram is provided showing the superimposed level signal onto the blanking region of an image frame, such as... Figure 5As shown, the EFSYNC signal (frame synchronization signal) indicates the start of a new frame, and the FrameValid signal (frame validity signal) indicates the transmission time of valid pixel data in the image frame. The image sensor can determine the location of the blanking region of an image frame based on the EFSYNC and FrameValid signals and store the level signal in the blanking region of one or more image frames. Alternatively, the image sensor can superimpose the level signal into a memory used to store the image sensor's ID, and the image sensor's I2C or SPI control bus can send the level signal to the image processing module. It is understandable that the level signal can also be stored in other registers and sent to the image processing module via the control bus.

[0072] The storage module stores configuration parameters corresponding to different voltage level combinations. The image processing module retrieves the corresponding configuration parameters, including sensor configuration parameters and image configuration parameters, from the storage module based on the corresponding voltage level signal combination transmitted from the image sensor. The intelligent image processing module sends different sensor configuration parameters to the image sensor, and simultaneously adjusts its own exposure and gain parameters based on the image configuration parameters to achieve the best matching effect.

[0073] In this embodiment, based on the mounting characteristics of the lens and lens mount, metallized and / or non-metallized connectors are used to connect the image sensor and the mount. The image sensor, combined with a pull-up circuit module, acquires level signals and identifies the lens based on the acquired level signals. The image sensor stores the level signals in a register and transmits them via I2C or SPI bus, or embeds the level signals within the blanking area of ​​the image frame and uses MIPI or LVDS bus for level signal synchronization. Without setting up additional communication paths, the image processing module retrieves the corresponding processing matching parameters from the storage module based on the acquired level signals, configures the image sensor parameters, and adjusts its own adaptation parameters. Based on the method in this embodiment, lens identification and configuration can be achieved without assembling a memory chip or MPU (Microprocessor Unit) on the lens body, and without installing an impedance identification network on the resistor adapter board. It can support passive fixed-focus lenses with only structural components and glass and no electrical properties.
