[0001] This utility model relates to the field of image acquisition technology, and in particular to a camera, a video recording device, and a smart furniture. Background Technology

[0002] Currently, achieving wide-angle (or macro) and telephoto photography requires two separate modules. Furthermore, as zoom focal lengths increase, the module size also grows larger, making it increasingly difficult to place camera modules within the existing device dimensions. Therefore, current camera modules struggle to integrate wide-angle and telephoto shooting, resulting in significant space requirements. Utility Model Content

[0003] In view of the above problems, embodiments of the present invention are proposed to provide a camera, a video recording device, and a smart furniture that overcome or at least partially solve the above problems.

[0004] To address the aforementioned problems, in a first aspect of this utility model, an embodiment of this utility model discloses a camera comprising:

[0005] A camera frame with an internal cavity;

[0006] A lens module is disposed at the light-incident position of the camera frame;

[0007] A reflector is disposed in the receiving cavity and intersects with the lens module;

[0008] An imaging sensor is disposed within the cavity;

[0009] A movable structure is disposed within the receiving cavity and connected to the imaging sensor;

[0010] During wide-angle shooting, the moving structure is used to drive the imaging sensor to be positioned between the mirror and the lens module, and light passes through the lens module to reach the imaging sensor;

[0011] During telephoto shooting, the moving structure is used to drive the imaging sensor to move in a direction away from the mirror and perpendicular to the lens module. Light passes through the lens module and the mirror in sequence to reach the imaging sensor.

[0012] Optionally, the moving structure includes:

[0013] An L-shaped sliding track is fixed in the receiving cavity, with the straight end located between the reflector and the lens module, and the right-angle end located on the side away from the reflector;

[0014] The substrate is connected to the imaging sensor and is used to fix the imaging sensor and drive the imaging sensor to slide on the L-shaped sliding track.

[0015] Optionally, the moving structure further includes:

[0016] An arc-shaped auxiliary track, located at the right-angle end of the L-shaped sliding track, is used to assist the rotation of the imaging sensor.

[0029] The embodiments of this utility model have the following advantages:

[0030] This utility model embodiment includes a camera frame with an internal cavity; a lens module disposed at the light-incident position of the camera frame; a reflector disposed in the cavity, intersecting with the lens module; an imaging sensor disposed in the cavity; and a moving structure disposed in the cavity and connected to the imaging sensor. During wide-angle shooting, the moving structure drives the imaging sensor to be positioned between the reflector and the lens module, with light passing through the lens module to reach the imaging sensor. During telephoto shooting, the moving structure drives the imaging sensor to move in a direction away from the reflector and perpendicular to the lens module, with light passing sequentially through the lens module and the reflector to reach the imaging sensor. By moving the imaging sensor to the corresponding position during wide-angle or telephoto shooting to achieve imaging, and by using the same lens module, the same camera frame, and the same imaging sensor for both wide-angle and telephoto shooting, the corresponding components for wide-angle and telephoto shooting can be integrated into the same camera. This integration of wide-angle and telephoto shooting, and the use of the same lens module, the same camera frame, and the same imaging sensor, can reduce the space occupied by the camera, making the camera more compact and miniaturized.

[0037] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Reference Figure 1 The diagram shows a front view and a top view of the structure of a camera embodiment of the present invention during wide-angle shooting; refer to Figure 2 The diagram shows a front view and a top view of the structure of a camera embodiment of the present invention during telephoto shooting; the camera may specifically include the following components:

[0039] A camera frame 2 with an internal cavity 5;

[0040] Lens module 4 is disposed at the light-incident position of the camera frame 2;

[0041] The reflector 7 is disposed in the receiving cavity 5 and is arranged intersecting with the lens module 4;

[0042] Imaging sensor 8 is disposed in the receiving cavity 5;

[0043] The movable structure 14 is disposed in the receiving cavity 5 and connected to the imaging sensor 8;

[0044] During wide-angle shooting, the moving structure 14 is used to drive the imaging sensor 8 to be located between the mirror 7 and the lens module 4, and the light passes through the lens module 4 to reach the imaging sensor 8;

[0045] During telephoto shooting, the moving structure 14 is used to drive the imaging sensor 8 to move in a direction away from the mirror 7 and perpendicular to the lens module 4. The light passes through the lens module 4 and the mirror 7 in sequence to reach the imaging sensor 8.

[0046] In this embodiment of the invention, the camera may include a camera frame 2, a lens module 4, a reflector 7, an imaging sensor 8, and a moving structure 14. The camera frame 2 serves as the supporting foundation for the lens module 4, reflector 7, imaging sensor 8, and moving structure 14, all of which can be housed within the camera frame 2. The camera frame 2 protects the lens module 4, reflector 7, imaging sensor 8, and moving structure 14 from damage, thereby ensuring the reliability of the camera. The camera frame 2 has an internal receiving cavity 5. The lens module 4, reflector 7, imaging sensor 8, and moving structure 14 can all be housed within the receiving cavity 5.

[0047] The lens module 4 is positioned at the light-incident location of the camera frame 2. The lens module 4 transmits light emitted from an object to the imaging sensor 8 by allowing light to pass through. The lens module 4 can include, but is not limited to, spherical lenses (with a standard spherical curvature, simple manufacturing process, and low cost); aspherical lenses (with complex aspherical curves, eliminating spherical and coma aberrations, reducing the number of lenses (e.g., from 5 to 3 in a mobile phone camera), and shrinking the module size); low-dispersion lenses (using low-dispersion glass such as ED glass, suppressing purple / green fringing in high-contrast scenes, improving clarity); and freeform lenses (with irregular and complex curved surfaces, correcting wide-angle distortion (e.g., edge stretching in fisheye lenses), replacing multi-lens combinations, and reducing module thickness). The lens module 4 can be made of the following materials: glass lenses with over 90% light transmittance and resistance to high-temperature aging; and plastic lenses using PMMA / PC materials, which are easy to mold aspherical structures, reducing costs by 40%-60%. The glass-plastic hybrid lens, using a 1G4P (one glass element combined with four plastic elements) configuration, balances chromatic aberration correction and volume control. Multiple elements work together to correct aberrations and improve resolution (e.g., supporting hundreds of millions of pixels). The molded glass elements are formed by high-temperature softening and die-casting, balancing light transmittance and mass production feasibility.

[0048] The mirror 7 is housed in the cavity 5 and intersects with the lens module 4. It can reflect the light entering through the lens module 4 to the imaging sensor 8. The mirror 7 can be raised at the moment of shooting, allowing light to be directly projected onto the imaging sensor 8 (such as CMOS / CCD). In addition, the mirror 7 can also refract some light to an independent phase-detection autofocus module to assist focusing.

[0049] The imaging sensor 8 is the core component for imaging. Located within the housing cavity 5, it converts light signals into electrical signals, and its performance directly affects image quality. The imaging sensor 8 can be of, but is not limited to, the following types:

[0050] CCD (Charge-Coupled Device), working principle: It converts photons into electrons through the photoelectric effect, and the charge is transferred line by line to the output node, where it is amplified and converted into a voltage signal. Structural characteristics: It consists of photodiodes and vertical / horizontal shift registers. The charge must be transferred sequentially and is controlled by an external clock signal.

[0051] CMOS (Complementary Metal-Oxide-Semiconductor) operating principle: Each pixel integrates an amplifier and an ADC, directly outputting a digital signal. It is divided into front-illuminated (FSI) and back-illuminated (BSI) types. Structural characteristics: The pixel circuit includes a photodiode, amplifier, and switching transistor, supporting random access.

[0052] A global shutter sensor eliminates the rolling shutter effect by exposing all pixels simultaneously.

[0053] The movable structure 14 is located within the receiving cavity 5 and connected to the imaging sensor 8, allowing the imaging sensor 8 to move within the cavity 5. During wide-angle shooting, the movable structure 14 drives the imaging sensor 8 to be positioned between the reflex mirror 7 and the lens module 4, allowing light to pass through the lens module 4 to reach the imaging sensor 8, thus achieving wide-angle shooting. During telephoto shooting, the movable structure 14 drives the imaging sensor 8 to move in a direction away from the reflex mirror 7 and perpendicular to the lens module 4, allowing light to pass sequentially through the lens module 4 and the reflex mirror 7 to reach the imaging sensor 8, thus achieving telephoto shooting.

[0054] This embodiment of the invention includes a camera frame 2 with an internal cavity 5; a lens module 4 disposed at the light-incident position of the camera frame 2; a reflector 7 disposed in the cavity 5, intersecting with the lens module 4; an imaging sensor 8 disposed in the cavity 5; and a moving structure 14 disposed in the cavity 5 and connected to the imaging sensor 8. During wide-angle shooting, the moving structure 14 drives the imaging sensor 8 to be positioned between the reflector 7 and the lens module 4, with light passing through the lens module 4 to reach the imaging sensor 8. During telephoto shooting, the moving structure 14 drives the imaging sensor 8 to move in a direction away from the reflector 7 and perpendicular to the lens module 4, with light passing sequentially through the lens module 4 and the reflector 7 to reach the imaging sensor 8. By moving the imaging sensor 8 to the corresponding position during wide-angle or telephoto shooting, an image is formed. Both wide-angle and telephoto shooting are achieved by using the same lens module 4, the same camera frame 2, and the same imaging sensor 8. This integrates the corresponding components for wide-angle and telephoto shooting, allowing them to be integrated into the same camera. Furthermore, by using the same lens module 4, the same camera frame 2, and the same imaging sensor 8, the space occupied by the camera can be reduced, making the camera more compact and miniaturized.

[0055] Further references can be used. Figure 3 The diagram shows a structural outline of a camera embodiment of the present invention; the camera may specifically include the following components:

[0056] A camera frame 2 with an internal cavity 5;

[0057] Lens module 4 is disposed at the light-incident position of the camera frame 2;

[0058] The reflector 7 is disposed in the receiving cavity 5 and is arranged intersecting with the lens module 4;

[0059] Imaging sensor 8 is disposed in the receiving cavity 5;

[0060] The movable structure 14 is disposed in the receiving cavity 5 and connected to the imaging sensor 8;

[0061] The filter 6 is located on the side of the lens module 4 closest to the imaging sensor 8;

[0062] The lens cover 3 is connected to the camera frame 2, and the filter 6 and the lens module 4 are located in the lens cover 3;

[0063] Flexible circuit board 1 is connected to the camera frame 2;

[0064] During wide-angle shooting, the moving structure 14 is used to drive the imaging sensor 8 to be located between the mirror 7 and the lens module 4, and the light passes through the lens module 4 to reach the imaging sensor 8;

[0065] During telephoto shooting, the moving structure 14 is used to drive the imaging sensor 8 to move in a direction away from the mirror 7 and perpendicular to the lens module 4. The light passes through the lens module 4 and the mirror 7 in sequence to reach the imaging sensor 8.

[0066] In this embodiment of the utility model, the camera may include a flexible circuit board 1, a camera frame 2, a lens barrel cover 3, a lens module 4, a reflector 7, a filter 6, an imaging sensor 8, and a moving structure 14. The camera frame 2 is the supporting foundation for the flexible circuit board 1, camera frame 2, lens barrel cover 3, lens module 4, reflector 7, filter 6, imaging sensor 8, and moving structure 14. The camera frame 2 has a receiving cavity 5 inside, and the lens module 4, reflector 7, filter 6, imaging sensor 8, and moving structure 14 can all be disposed in the receiving cavity 5. The flexible circuit board 1 is connected to the camera frame 2 and interacts with the internal motor, imaging sensor 8, and other circuits to achieve driving. It can also transmit images. The flexible circuit board 1 is mainly composed of the following parts: (1) Substrate, usually made of polyimide (PI) or polyester (PET), which has high temperature resistance and bending resistance. Thickness: The common thickness is 12.5μm~50μm, and the ultra-thin design is suitable for miniaturized cameras (such as mobile phone modules). (2) Conductive layer: The copper foil is made of rolled copper (RA) or electrolytic copper (ED), with a thickness of 9μm to 35μm. (3) Coverlay: Protects the circuit and prevents oxidation and short circuits. The material is polyimide or photoimageable solder mask (PSMR). (4) Stiffener: Increases rigidity in the connector or soldering area (such as the connection between the camera module and the motherboard). The material is FR4 (glass fiber epoxy resin), stainless steel, or aluminum sheet.

[0067] The lens cover 3 is connected to the camera frame 2. The filter 6 and the lens module 4 can be set in the lens cover 3, and the lens cover 3 protects the filter 6 and the lens module 4.

[0068] The lens module 4 is positioned at the light-incident position of the camera frame 2, allowing light from an object to enter the camera frame 2 through the lens module 4. The reflector 7 can be disposed in the receiving cavity 5, intersecting with the lens module 4, meaning the reflector 7 is tilted relative to the lens module 4. The tilt angle can be determined based on the specific structure of the camera, and this embodiment of the present invention does not impose a limitation.

[0069] The filter 6 is located on the side of the lens module 4 closest to the imaging sensor 8, that is, the filter 6 is positioned below the lens module 4 and is attached to the imaging sensor 8. The filter 6 can be a separate module for the imaging sensor 8; it can also be integrated into a single module, and this embodiment of the invention does not specifically limit this. The filter 6 is used to control the characteristics of light entering the sensor, directly affecting image color reproduction, sharpness, and imaging effects in special scenes. The filter 6 includes, but is not limited to, the following types:

[0070] (1) Infrared cut-off filter (IR-Cut Filter)

[0071] Function: To block infrared light (wavelengths above 700nm) invisible to the human eye, preventing infrared light from interfering with visible light imaging (CMOS sensors are sensitive to infrared light, which can cause color distortion). Types include reflective types, which use multi-layered dielectric films to reflect infrared light (such as blue glass filters); and absorptive types, which use special materials (such as dye-containing resins) to absorb infrared light.

[0072] (2) Ultraviolet-cut filter

[0073] Function: Filters ultraviolet rays (<400nm) to prevent fogging caused by ultraviolet light (especially in high-altitude and snowy environments). Material: Coated quartz glass or with added UV absorbers.

[0074] (3) Color Filter Array (CFA)

[0075] Function: To cover the sensor surface with an RGB (three primary colors) or RGGB mosaic filter so that each pixel captures only a single color.

[0076] (2) Neutral Density Filter (ND Filter)

[0077] Function: To uniformly attenuate light of all wavelengths, reduce the amount of light entering the eye, and prevent overexposure. Types: Fixed ND: such as ND8. Variable ND: Achieved through continuous adjustment via superimposed polarizers.

[0078] An imaging sensor 8 is placed in the housing cavity 5 and converts the light passing through the lens module 4 or the light reflected by the mirror 7 into an electrical signal, thereby enabling imaging.

[0079] The movable structure 14 is housed in the receiving cavity 5 and connected to the imaging sensor 8. It can move the imaging sensor 8 to different positions for corresponding shooting. In wide-angle shooting, the movable structure 14 can drive the imaging sensor 8 to be positioned between the mirror 7 and the lens module 4. Light passes through the lens module 4 to reach the imaging sensor 8, achieving wide-angle shooting. In telephoto shooting, the movable structure 14 drives the imaging sensor 8 to move away from the mirror 7 and perpendicular to the lens module 4. Light passes sequentially through the lens module 4 and the mirror 7 to reach the imaging sensor 8, achieving telephoto shooting.

[0080] You can refer to Figure 4 In an optional embodiment of this utility model, the movable structure 14 includes:

[0081] The L-shaped sliding track 11 is fixed in the receiving cavity 5, with the straight end located between the reflector 7 and the lens module 4, and the right-angle end located on the side away from the reflector 7.

[0082] The substrate 9 is connected to the imaging sensor 8 and is used to fix the imaging sensor 8 and drive the imaging sensor 8 to slide on the L-shaped sliding track 11.

[0083] In this embodiment of the invention, the movable structure 14 may include an L-shaped sliding track 11 and a substrate 9. The substrate 9 is connected to the imaging sensor 8 and can be fixedly connected to the imaging sensor 8. The substrate 9 can slide freely on the L-shaped sliding track 11, and can slide to the straight end and right-angle end of the L-shaped sliding track 11. When the substrate 9 slides, it drives the imaging sensor 8 to slide on the L-shaped sliding track 11, thereby reaching the corresponding imaging position, thus achieving better imaging and ensuring imaging effect. The L-shaped sliding track 11 is fixed in the receiving cavity 5. In one example, the L-shaped sliding track 11 can be fixed in the receiving cavity 5 by the bracket 12 to ensure the stability of the position of the L-shaped sliding track 11. The straight end of the L-shaped sliding track 11 is located between the reflector 7 and the lens module 4, i.e. Figure 4 As shown, the left segment is the straight end of the L-shaped sliding track 11. The right-angle end is located on the side away from the reflector 7, i.e. Figure 4 As shown, the right-hand section is the right-angle end of the L-shaped sliding track 11.

[0084] In an optional embodiment of this invention, the moving mechanism further includes an arc-shaped auxiliary track 13 located at the right-angle end of the L-shaped sliding track 11, used to assist the imaging sensor 8 in rotating. When the substrate 9 slides onto the arc-shaped auxiliary track 13, the arc-shaped auxiliary track 13 assists the substrate 9 in rotating, thereby assisting the imaging sensor 8 in rotating so that the imaging sensor 8 is perpendicular to its previous state, thus enabling rapid position changes.

[0085] In an optional embodiment of the present invention, the movable structure 14 further includes: a pulley 10, fixed to the base plate 9, and partially embedded in the L-shaped sliding track 11.

[0086] A pulley 10 is fixed on one side of the substrate 9 near the L-shaped sliding track 11. The pulley 10 is partially embedded in the L-shaped sliding track 11. The substrate 9 and the imaging sensor 8 move on the L-shaped sliding track 11 by sliding, thereby reducing friction.

[0087] In an optional embodiment of the present invention, the moving structure 14 further includes a drive motor (not shown in the figure), which is connected to the pulley 10 and is used to drive the pulley 10.

[0088] A drive motor can be used as the power source for driving, and the drive motor is connected to the pulley 10. When the drive motor moves, it drives the pulley 10 to move, thereby moving the substrate 9 and the imaging sensor 8.

[0089] In summary, the camera's operation process is as follows: Figure 1 , Figure 3 and Figure 4 As shown, when the user turns on the camera, it defaults to wide-angle mode. The imaging sensor 8 and substrate 9 are located directly below the lens module 4 by default. When the user taps the telephoto lens to take a picture, the phone drives the pulley 10 to rotate clockwise via the driver of the pulley 10, moving the imaging sensor 8 and substrate 9 to the right side along the L-shaped sliding track 11. Conversely, when the user switches to wide-angle mode, the phone drives the track pulley 10 to rotate counterclockwise via the driver of the pulley 10, moving the imaging sensor 8 and substrate 9 to the position directly below the lens module 4 along the L-shaped sliding track 11.

[0090] This embodiment of the invention includes a camera frame 2 with an internal cavity 5; a lens module 4 disposed at the light-incident position of the camera frame 2; a reflector 7 disposed in the cavity 5, intersecting with the lens module 4; an imaging sensor 8 disposed in the cavity 5; a moving structure 14 disposed in the cavity 5 and connected to the imaging sensor 8; a filter 6 located on the side of the lens module 4 near the imaging sensor 8; a lens barrel cover 3 connected to the camera frame 2, with the filter 6 and the lens module 4 located within the lens barrel cover 3; and a flexible circuit board 1 connected to the camera frame 2. During wide-angle shooting, the moving structure 14 drives the imaging sensor 8 to be positioned between the reflector 7 and the lens module 4, with light passing through the lens module 4 to reach the imaging sensor 8. During telephoto shooting, the moving structure 14 drives the imaging sensor 8 to move away from the reflector 7 and perpendicular to the lens module 4, with light passing sequentially through the lens module 4 and the reflector 7 to reach the imaging sensor 8. By moving the imaging sensor 8 to the corresponding position during wide-angle or telephoto shooting, an image is formed. Both wide-angle and telephoto shots utilize the same lens module 4, the same filter 6, the same camera frame 2, and the same imaging sensor 8. This integrates the corresponding components for wide-angle and telephoto shooting into a single camera, achieving seamless integration of wide-angle and telephoto capabilities. Furthermore, the use of the same lens module 4, filter 6, camera frame 2, and imaging sensor 8 reduces the space occupied by the camera, making it more compact and miniaturized. The image is also transmitted via the same flexible circuit board 1, achieving structural and electrical integration and further reducing the camera's footprint.

[0091] This utility model embodiment also discloses a camera device, including the camera described above.

[0092] The imaging device may include a display component, a power supply component, and a camera as described above. The power supply component provides power to the display component and the camera. After the camera captures an image, it can transmit the image to the display component for display.

[0093] Display components include, but are not limited to, liquid crystal displays (LCDs), organic light-emitting diode (OLED) displays, and miniature LED / micro LED displays. LCDs control light transmittance by deflecting liquid crystal molecules under an electric field. A backlight module (such as LEDs) provides the light source, and the liquid crystal layer (sandwiched between two polarizers) adjusts the molecular alignment according to voltage, filtering specific wavelengths of light to form a color image. OLED displays consist of an array of self-emissive diodes made of organic materials; each pixel emits light independently, eliminating the need for a backlight. Color and brightness are adjusted by controlling the current intensity through a driving circuit. Mini LEDs reduce the size of LED backlight beads (0.1-0.3mm) and achieve local dimming technology to control local light, improving contrast and HDR effects. Micro LEDs shrink the LED chip size to the micrometer level (<50μm), with each pixel emitting light independently, eliminating the need for a liquid crystal layer.

[0098] An imaging sensor is disposed within the cavity;

[0099] A movable structure is disposed within the receiving cavity and connected to the imaging sensor;

[0100] During wide-angle shooting, the moving structure is used to drive the imaging sensor to be positioned between the mirror and the lens module, and light passes through the lens module to reach the imaging sensor;

[0101] During telephoto shooting, the moving structure is used to drive the imaging sensor to move in a direction away from the mirror and perpendicular to the lens module. Light passes through the lens module and the mirror in sequence to reach the imaging sensor.

[0102] Optionally, the moving structure includes:

[0103] An L-shaped sliding track is fixed in the receiving cavity, with the straight end located between the reflector and the lens module, and the right-angle end located on the side away from the reflector;

[0104] The substrate is connected to the imaging sensor and is used to fix the imaging sensor and drive the imaging sensor to slide on the L-shaped sliding track.

[0105] Optionally, the moving structure further includes:

[0106] An arc-shaped auxiliary track, located at the right-angle end of the L-shaped sliding track, is used to assist the rotation of the imaging sensor.

[0107] Optionally, the moving structure further includes:

[0108] The pulley is fixed to the base plate and partially embedded in the L-shaped sliding track.

[0109] Optionally, the moving structure further includes:

[0110] A drive motor is connected to the pulley and is used to drive the pulley.

[0111] Optionally, the camera further includes:

[0112] A filter is located on the side of the lens module closest to the imaging sensor.

[0113] Optionally, the camera further includes:

[0114] A lens cover is connected to the camera frame, and the filter and the lens module are located inside the lens cover.

[0115] Optionally, the camera further includes:

[0116] A flexible circuit board is connected to the camera frame.

[0117] This utility model embodiment includes a camera frame with an internal cavity; a lens module disposed at the light-incident position of the camera frame; a reflector disposed in the cavity, intersecting with the lens module; an imaging sensor disposed in the cavity; and a moving structure disposed in the cavity and connected to the imaging sensor. During wide-angle shooting, the moving structure drives the imaging sensor to be positioned between the reflector and the lens module, with light passing through the lens module to reach the imaging sensor. During telephoto shooting, the moving structure drives the imaging sensor to move in a direction away from the reflector and perpendicular to the lens module, with light passing sequentially through the lens module and the reflector to reach the imaging sensor. By moving the imaging sensor to the corresponding position during wide-angle or telephoto shooting to achieve imaging, and by using the same lens module, the same camera frame, and the same imaging sensor for both wide-angle and telephoto shooting, the corresponding components for wide-angle and telephoto shooting can be integrated into the same camera. This integration of wide-angle and telephoto shooting, and the use of the same lens module, the same camera frame, and the same imaging sensor, can reduce the space occupied by the camera, making the camera more compact and miniaturized.

[0118] This utility model discloses a smart furniture, including the camera device described above.

[0119] Smart furniture may include a controller and a camera device as described above. The controller can control the camera device to acquire images accordingly. After the camera device acquires images, it can transmit them to the controller. The controller analyzes the images to perform corresponding recognition functions. These recognition functions include, but are not limited to, object detection and classification, scene recognition, image semantic segmentation, behavior recognition, gesture recognition, and optical character recognition.

[0120] 1. Object detection and classification

[0121] Convolutional Neural Networks (CNNs) automatically extract multi-level features from images: low-level convolutional kernels capture local information such as edges and textures, while high-level networks combine these features to form a holistic representation of the object. Detection models (such as YOLO and Faster R-CNN) generate candidate regions on feature maps and determine the object category by regressing bounding box coordinates and classification branches; classification models (such as ResNet) directly perform Softmax classification on the entire image features and output the label of the category with the highest probability.

[0122] 2. Scene Recognition

[0123] Classification is based on global semantic features of images. Handcrafted features such as color histograms and GIST descriptors are extracted and combined with support vector machines (SVM) for classification. Deep learning methods utilize deep networks of CNNs (such as PlacesCNN) to automatically learn abstract representations of scenes (such as "beach" corresponding to the combination of blue sky, seawater, and sand). Finally, the scene category probability is output through fully connected layers.

[0124] 3. Image semantic segmentation

[0125] A pixel-level classification is achieved using an encoder-decoder architecture. The encoder (e.g., ResNet) progressively downsamples through convolution and pooling to extract high-level semantic features; the decoder restores spatial resolution through deconvolution or upsampling and fuses low-level detail information with skip connections (e.g., U-Net). Finally, a Softmax function is applied to each pixel to generate a probability map with the same number of classes, and the segmentation boundary is optimized using cross-entropy loss.

[0126] 4. Behavior recognition

[0127] Modeling dynamic behavior in videos by combining spatiotemporal features. A two-stream network processes RGB frames (appearance features) and optical flow maps (motion features) separately, unifying the spatiotemporal dimensions through late fusion or 3D convolution; 3D CNNs (such as C3D) directly convolve on the spatiotemporal cube to capture the temporal dependencies of actions; temporal models (such as LSTM, Transformer) further process sequence features and output the probability of behavior categories.

[0128] 5. Gesture recognition

[0129] Classification is achieved by detecting key points or feature regions of the hand. Traditional methods locate the hand based on skin color detection (HSV threshold), extract geometric features such as contours and convex hulls, and combine template matching or SVM for classification; deep learning methods use CNNs (such as MobileNet) to extract hand features, or use key point detection models (such as OpenPose) to locate finger joint coordinates, and input the spatial coordinate sequence into a temporal model (such as TCN) to identify the gesture category.

[0130] 6. Optical Character Recognition (OCR)

[0131] Text recognition is achieved using sequence modeling methods. Traditional processes first locate character regions through connected component analysis, extract features such as contours and stroke density, and then decode using dictionary matching or Hidden Markov Models (HMMs). Deep learning methods (such as CRNNs) use CNNs to extract character features, RNNs to model temporal dependencies, and the CTC loss function to align the predicted sequence with the true label, thus achieving end-to-end text recognition.

[0133] A camera frame with an internal cavity;

[0134] A lens module is disposed at the light-incident position of the camera frame;

[0135] A reflector is disposed in the receiving cavity and intersects with the lens module;

[0136] An imaging sensor is disposed within the cavity;

[0137] A movable structure is disposed within the receiving cavity and connected to the imaging sensor;

[0138] During wide-angle shooting, the moving structure is used to drive the imaging sensor to be positioned between the mirror and the lens module, and light passes through the lens module to reach the imaging sensor;

[0139] During telephoto shooting, the moving structure is used to drive the imaging sensor to move in a direction away from the mirror and perpendicular to the lens module. Light passes through the lens module and the mirror in sequence to reach the imaging sensor.

[0140] Optionally, the moving structure includes:

[0141] An L-shaped sliding track is fixed in the receiving cavity, with the straight end located between the reflector and the lens module, and the right-angle end located on the side away from the reflector;

[0142] The substrate is connected to the imaging sensor and is used to fix the imaging sensor and drive the imaging sensor to slide on the L-shaped sliding track.

[0143] Optionally, the moving structure further includes:

[0144] An arc-shaped auxiliary track, located at the right-angle end of the L-shaped sliding track, is used to assist the rotation of the imaging sensor.

[0155] This utility model embodiment includes a camera frame with an internal cavity; a lens module disposed at the light-incident position of the camera frame; a reflector disposed in the cavity, intersecting with the lens module; an imaging sensor disposed in the cavity; and a moving structure disposed in the cavity and connected to the imaging sensor. During wide-angle shooting, the moving structure drives the imaging sensor to be positioned between the reflector and the lens module, with light passing through the lens module to reach the imaging sensor. During telephoto shooting, the moving structure drives the imaging sensor to move in a direction away from the reflector and perpendicular to the lens module, with light passing sequentially through the lens module and the reflector to reach the imaging sensor. By moving the imaging sensor to the corresponding position during wide-angle or telephoto shooting to achieve imaging, and by using the same lens module, the same camera frame, and the same imaging sensor for both wide-angle and telephoto shooting, the corresponding components for wide-angle and telephoto shooting can be integrated into the same camera. This integration of wide-angle and telephoto shooting, and the use of the same lens module, the same camera frame, and the same imaging sensor, can reduce the space occupied by the camera, making the camera more compact and miniaturized.
