[0025] Figure 1 According to certain embodiments of the present disclosure, a camera sight system is disclosed.

[0026] In some embodiments, the camera sight system 10 includes a camera module 100 and a glasses module 200. The camera module 100 includes a sensor device 110, an anti-shake device 120, a zoom device 130, and a communication module 140, and the glasses module 200 includes a display device 210 and a communication module 220. The display device 210 includes an icon 211 and a micro-display 212. For example, the user can wear the glasses module 200. In some embodiments, the communication module 140 of the camera module 100 can be connected to the communication module 220 in the glasses module 200 for communication, and the link 11 can be a wireless link established between the Wi-Fi modules 143 and 223, or a physical transmission line between the USB Type-C interfaces 141 and 221, or the HDMI interfaces 142 and 222. The camera module 100 can transmit the detected scene image or target image to the glasses module 200 via the link 11, and the micro-display 212 on the glasses module 200 displays the scene image or target image. The glasses module 200 can receive a display signal from the camera module 100 to display the icon 211 and the display screen on the micro display 212. In some embodiments, the communication module 220 includes a USB Type-C interface 221, an HDMI interface 222, and a Wi-Fi module 223, and the glasses module 200 can receive a display signal from the camera module 100 or other devices through the USB Type-C interface 221, the HDMI interface 222, or the Wi-Fi module 223 in the communication module 220, and display the display signal on the micro display 212.

[0027] In some embodiments, the sensing device 110 includes a laser rangefinder 111 and a sensor 118. In some embodiments, the camera module 100 can measure the distance between the target object and the camera module 100 via the laser rangefinder 111. In some embodiments, the sensor 118 can sense the light of the scene or the target object via the periscope 131 and the lens 132 to generate a sensed image. The sensor 118 can be one of a color image sensor (CIS) 112, a thermal imager 113, a night vision device 114, and a GeSi (germanium silicon) sensor 115. In other words, the camera sight system 10 can be configured with different sensors 118 on different product models according to different usage requirements and scenarios. In some embodiments, when the camera sight system 10 is used in a daytime scene, the sensor 118 configured by the camera sight system 10 can use a color image sensor 112 to sense a color image. In other embodiments, when the camera sight system 10 is used for night scenes, the sensor 118 may use a thermal imager 113 to detect the thermal radiation information of the target to obtain a thermal image of the target, or the sensor 118 may use a night vision device 114 to observe the target at night using infrared (IR) to obtain an infrared image of the target. In some other embodiments, when the camera sight system 10 is used for 3D sensing, the sensor 118 may use a GeSi sensor 115 to sense the infrared light image of the target using short-wave infrared light. In addition, the GeSi sensor 115 has a 3D time of flight (ToF) depth detection function, which can also be used to measure the distance of the target. In some embodiments, when the camera sight system 10 is configured with a GeSi sensor 115, the laser rangefinder 111 may be omitted. For ease of explanation, in the embodiments described below, the sensor 118 uses a color image sensor 112 to sense the light of the scene or target.

[0028] In some embodiments, the camera module 100 may be disposed on the anti-shake device 120 to achieve vibration resistance and impact resistance. The anti-shake device 120 includes an optical anti-shake voice coil motor (which may be called a VCM-OIS motor) 121, which can use the Lorentz force between the energized coil and the magnet to drive the zoom device 130 to move and achieve the required optical anti-shake function. In some embodiments, the anti-shake device 120 further includes a vibration reduction device 122, a vibration reduction assembly 123, a gyroscope 124 and a piezoelectric sheet 125, wherein the piezoelectric sheet 125 is an active control vibration reduction device, and the vibration reduction device 122, the vibration reduction assembly 123 and the gyroscope 124 are passive control vibration reduction devices, and the details will be described in detail later.

[0029] In some embodiments, the zoom device 130 includes a periscope 131 (eg, including Figure 2A-2B131A to 131D), a lens (scope) 132, an auto focus (AF) motor 133, and a prism 134 (for example, including prisms 134A to 134D) as shown. In some embodiments, the periscopes 131A to 134D can be implemented by lenses, for example. In some embodiments, the user can operate the glasses module 200 (or through other external control devices) to generate a control signal for controlling the optical zoom ratio to transmit to the camera module 100, and the AF motor 133 can control the displacement of the periscopes 131A to 134D in the horizontal direction or the vertical direction according to the control signal, so as to adjust the focal length of the periscopes 131A to 134D and the length of the optical path of the incident light sensed by the sensor 118, thereby realizing the high-magnification optical zoom function of the camera module 100. In some embodiments, the AF motor 133 can be integrated into the VCM-OIS motor 121, that is, the VCM-OIS motor 121 can include a function to drive the zoom device 130 to move to achieve the required auto focus and optical image stabilization. It should be noted that the smartphones currently on the market that use periscope designs (such as Apple phones and Android phones) use a fixed focal length (i.e., a telephoto fixed-focus lens). Although their lens modules can achieve 3x or 5x optical focal lengths through the periscope, they cannot adjust their focal lengths, so image blur may occur at certain focal lengths. In addition, these smartphones are only equipped with OIS optical image stabilization functions, and are not specially designed with active or passive vibration reduction functions to protect the lens group against more severe external vibrations.

[0030] Figure 2A For some embodiments according to the present disclosure, a first zoom configuration of a camera module is disclosed.

[0031] like Figure 2AAs shown, in the first zoom configuration of the camera module 100, the periscopes 131A and 131B are disposed between the prisms 134B and 134C, and the zoom device 130 does not include the periscopes 131C and 131D. The incident light, for example, enters the color image sensor 112 along the optical path 230 by sequentially passing through the lens 132 (transmission), the prism 134A (90-degree refraction), the prism 134B (90-degree refraction), the periscope 131A (transmission), the periscope 131B (transmission), the prism 134C (90-degree refraction), and the prism 134D (90-degree refraction). In some embodiments, the periscopes 131A and 131B in the area 250 can be considered as a periscope group as a whole, and the displacement of the periscope group in a first direction (e.g., X-axis) can be controlled by the AF motor 133, thereby adjusting the focal length of the periscopes 131A and 131B to change the overall length of the optical path 230. Therefore, the camera sight system 10 can achieve the function of fast zooming of the telephoto lens. In other embodiments, the AF motor 133 can separately control the displacement of the periscopes 131A and 131B in the first direction (e.g., X-axis), thereby adjusting the focal length of the periscopes 131A and 131B to change the overall length of the optical path 230. Under this hardware configuration, the camera sight system 10 can also achieve the function of fast zooming of the telephoto lens.

[0032] Figure 2B For some embodiments according to the present disclosure, a second zoom configuration of the camera module is disclosed.

[0033] like Figure 2BAs shown, in the second zoom configuration of the camera module 100, the periscopes 131A and 131B are disposed between the prisms 134A and 134B, and the periscopes 131C and 131D are disposed between the prisms 134C and 134D. The incident light, for example, enters the color image sensor 112 along the optical path 232 by sequentially passing through the lens 132 (transmission), the prism 134A (90-degree refraction), the periscope 131A (transmission), the periscope 131B (transmission), the prism 134B (90-degree refraction), the prism 134C (90-degree refraction), the periscope 131C (transmission), the periscope 131D (transmission), and the prism 134D (90-degree refraction). In some embodiments, the periscopes 131A and 131B in the area 260 can be considered as a first periscope group as a whole, and the periscopes 131C and 131D can be considered as a second periscope group as a whole. The AF motor 133 can control the displacement of the first periscope group and the second periscope group in the second direction (e.g., the Y axis) respectively, thereby adjusting the focal lengths of the periscopes 131A to 131D to change the overall length of the optical path 232. Therefore, the camera sight system 10 can achieve the function of fast zooming of the telephoto lens. In other embodiments, the AF motor 133 can control the displacement of the periscopes 131A to 131D in the second direction (e.g., the Y axis) separately, thereby adjusting the focal lengths of the periscopes 131A and 131D to change the overall length of the optical path 232. Under this hardware configuration, the camera sight system 10 can also achieve the function of fast zooming of the telephoto lens.

[0034] Figure 3 A schematic diagram illustrating a usage scenario of a camera sighting system according to certain embodiments of the present invention is provided.

[0035] In some embodiments, the camera sight system 10 may be disposed in the scene 300, for example, the camera module 100 may be fixed above the shooting device 320 for aiming at the target 310, wherein the shooting device 320 is disposed on the support component 330, wherein the support component 330 may be a fixed gun mount or a mechanical arm, etc., for supporting and fixing the shooting device 320, and controlling the shooting and firing operation of the shooting device 320, but the present invention is not limited thereto. In addition, the camera module 100 is connected to the eyeglass module 200 through a link 11 (such as a Wi-Fi connection) for communication, and transmits the sensed scene image to the eyeglass module 200 through the link 11. And the user can wear the eyeglass module 200 to view the scene image from the micro display 212 on the display device 210. In addition, the display device 210 can further superimpose a crosshair pattern on the scene image to facilitate the user to aim at the target 310 and fire. In some embodiments, the user can send a control signal to the support component 330 (e.g., a robotic arm) through the glasses module 200 to adjust the aiming direction of the shooting device 320. In other embodiments, the user does not need to bring the eyes close to the camera module 100 for aiming, and the user can use other physical objects to adjust the aiming direction of the shooting device 320, so that the user can aim at the target 310 and fire.

[0036] Figure 4 According to certain embodiments of the present invention, a schematic diagram of a first configuration of the passive anti-shake function of a camera sight system is disclosed. Figure 1 , Figure 3 and Figure 4 .

[0037] In some embodiments, because the camera module 100 is fixed to a shooting device (such as Figure 3 When a user uses the shooting device to shoot, the camera module 100 is easily damaged due to the severe vibration during shooting. Therefore, an energy dissipation and vibration reduction structure or a tuning and vibration reduction structure can be added to the structure of the camera module 100 in the present invention to passively reduce vibration to achieve the anti-shake function.

[0038] In some embodiments, Figure 4 As shown, the vibration reduction structure 400 includes a main system 410 and a vibration reduction device 122, wherein the main system 410 is, for example, disposed in the housing 20 of the camera module 100. The tuning parameters of the main system 410 are (m1, d1, k1), indicating that it has an effective mass m1, a damping coefficient d1, and an effective stiffness k1, and the vibration reduction device 122 is a tuned damper. In some embodiments, the main system 410, for example, includes at least Figure 1The sensor device 110 and the zoom device 130 are shown. In other embodiments, the main system 410 is, for example, Figure 1 The camera module 100 is shown.

[0039] The tuning parameters of the vibration reduction device 122 (i.e., tuned damper) are (m2, d2, k2), indicating that it has an equivalent mass m2, a damping coefficient d2, and an equivalent stiffness k2, which means that the equivalent mass m2 provides an inertial force, the damping coefficient d2 provides an energy dissipation mechanism, and the equivalent stiffness k2 provides a restoring force, and the natural frequency of the vibration reduction device 122 itself is close to the control frequency (including the fundamental frequency and the first frequency) of the main system 410. When the control frequency of the main system 410 is excited to generate violent vibrations, the vibration reduction device 122 will generate a resonant motion in the opposite direction to the main system 410 due to the inertia and restoring force of the equivalent mass 122. For example, the quadratic differential equation of the motion of the vibration reduction device 122 is: The second-order differential equation of motion of the main system 410 is roughly opposite to Therefore, during the vibration process, part of the energy of the main system 410 will be transferred to the vibration reduction device 122 and consumed by the damper (with a damping coefficient d2) in the vibration reduction device 122, thereby allowing the camera module 100 to achieve a vibration reduction function.

[0040] Figure 5 A schematic diagram of a second configuration of the passive anti-shake function of a camera sight system is disclosed according to some embodiments of the present invention.

[0041] In some embodiments, the camera module 100 includes a gyroscope 124, and the gyroscope 124 can be used, for example, Figure 5 For example, the gyroscope 500 includes a main frame 510, a gimbal 512, a spin axis 514, and a rotor 516. Therefore, when the rotor 516 of the gyroscope 500 rotates at a high speed, if a vibration occurs, the gyroscope 500 will shake in the direction of the vibration. If the vibration potential energy from the external force is lower than the rotational potential energy of the gyroscope 500, because the gyroscope 500 itself will rotate, the force point will move from the lower angle to the upper angle. Because the gyroscope 500 has the characteristic of conservation of angular momentum, the vibration potential energy still runs in the original direction, thereby allowing the camera module 100 to achieve the vibration reduction function.

[0042] Figure 6 A schematic diagram of a third configuration of the passive anti-shake function of a camera sight system is disclosed according to certain embodiments of the present invention.

[0043] In some embodiments, a vibration reduction assembly 123 is provided between the zoom device 130 of the camera module 100 and its housing 20. Figure 6As shown. The vibration reduction component 123 includes, for example, an elastic component and a damping component, wherein the elastic component includes a horizontal elastic component, a vertical elastic component, an axial elastic component, a horizontal axis rotation elastic component, a vertical axis rotation elastic component, and / or an axial rotation elastic component. The damping component includes a horizontal damping component, a vertical damping component, an axial damping component, a horizontal axis rotation damping component, a vertical axis rotation damping component, and / or an axial rotation damping component.

[0044] In a preferred embodiment, the mounting base ( Figure 6 A mass component is set on the Figure 4 The vibration reduction device 122 in the vibration reduction structure 400 shown has an equivalent mass m2. When the camera module 100 (such as a night vision telescope, a night vision sight, etc.) is subjected to a horizontal shake, the inertia of the zoom device 130 and the mass component generates a shake in the opposite direction, and the horizontal linear spring provides the zoom device 130 with a restoring force to pull it back in the opposite direction of the original shake, thereby forming a horizontal simple harmonic vibration, and the damping dissipates the energy of the shake to gradually stop the shake. Similarly, when the camera module 100 is subjected to a vertical shake, the vertical shake is gradually stopped due to the action of the vertical elastic component and the vertical damping component. When the night vision telescope is subjected to a torsional vibration along the horizontal axis, the lens inertia generates a torsional vibration in the opposite direction, and the horizontal axis rotation elastic component provides a restoring force to twist it in the opposite direction, thereby forming a simple harmonic vibration of the horizontal axis rotation, and the horizontal rotation damping component dissipates the energy of the torsional vibration to gradually stop the torsional vibration. Similarly, the torsional vibration of the vertical axis can also achieve the purpose of vibration reduction by a similar principle. In some embodiments, in order to achieve a better vibration reduction effect, elastic components, rotating elastic components, damping and rotating damping can be installed at a fixed angle (for example, 10°) between the camera module 100 and its housing 20, which can more effectively and quickly suppress vibrations transmitted from various angles.

[0045] Figure 7 A schematic diagram illustrating the active anti-shake function of a camera sighting system according to certain embodiments of the present invention is provided.

[0046] In some embodiments, a plurality of piezoelectric sheets 125 may be disposed on the same surface of the housing 20 of the camera module 100 to implement the active anti-shake function of the camera sight system. For example, the piezoelectric sheets 125 are disposed on the same surface of the housing 20 (e.g., including one of the top surface, the bottom surface, and the side surface) at fixed angles (e.g., 30 degrees, 45 degrees, 90 degrees, etc.). When the camera module 100 is affected by external vibration, each piezoelectric sheet 125 will also be synchronously affected by the external vibration and deformed, and the corresponding piezoelectric signal is fed back to the microcontroller ( Figure 1 Not shown), and the microcontroller can collect the piezoelectric signals generated by each piezoelectric sheet 125 and generate a control signal with the same frequency and amplitude in the opposite direction to feed back to each piezoelectric sheet 125, so that each piezoelectric sheet 125 can generate a reverse vibration to offset the external vibration, thereby achieving the effect of active vibration suppression and active anti-shake. In a preferred embodiment, three piezoelectric sheets 125 can be set on the same surface of the housing 20, and they are respectively set along the horizontal direction, the vertical direction and the 45-degree angle direction. Therefore, the microcontroller in the camera module 100 can use the piezoelectric signals detected by the three piezoelectric sheets 125 to more accurately analyze the amplitude, frequency and direction of the external vibration, and then generate a control signal with the same frequency and amplitude in the opposite direction to feed back to the three piezoelectric sheets 125, so that the three piezoelectric sheets 125 can generate a reverse vibration to offset the external vibration. In some embodiments, a group of three piezoelectric sheets 125 can be set in a similar manner on different surfaces of the housing 20 of the camera module 100 to achieve a similar active anti-vibration effect.
