The imaging device usually aligns with the observation target and then performs focusing after determining that the observation target is not clear. During the focusing process, the observation target needs to be included in the field of view of the imaging device all the time, but rotating the zoom ring or the focus ring may cause the imaging device to shake, and the observation target in the field of view of the imaging device changes, resulting in an increase in the focusing difficulty and the focusing time will also increase accordingly.

[0029] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] The following will be combined with Figure 1 and Figure 2, a description of an imaging device provided by the present utility model is given.

[0031] As Figure 1 shown, it is a structural block diagram of an imaging device provided by the present utility model, Figure 2 and a side view of the imaging device is shown. Specifically, the imaging device includes: an imaging main body 11, a housing 12, a sliding signal processing device 13, and an eyepiece 14.

[0032] Among them, the imaging main body 11 includes: an image sensor 111 and a barrel objective lens 112. The image sensor 111 is connected to the barrel objective lens 112 and is used to convert the optical signal collected by the barrel objective lens 112 into an image signal. The barrel objective lens 112 is connected to the housing 12 in a manner of being embedded in the cylindrical structure of the housing 12; the sliding signal processing device 13 is connected to the barrel objective lens and is used to generate a sliding signal according to the received sliding operation and control the barrel objective lens 112 to move closer to or away from the image sensor along the central axis; the eyepiece 14 is connected to the housing 12 and is used to enhance the display of the image collected by the imaging main body 11.

[0033] The imaging device of the present utility model can be a night vision device, a microscope, etc. The barrel objective lens 112 is connected to the housing 12 in a manner of being embedded in the cylindrical structure of the housing 12 (for example, the barrel-shaped eyepiece 112 is fixed on the housing 12 by a thread), as Figure 3 shown, it is a schematic diagram of the barrel objective lens. The barrel objective lens 112 can move forward (outwardly protruding) and backward (inwardly contracting) along the arrow direction as Figure 2 shown. Taking a night vision device as an example, when the barrel objective lens 112 protrudes outward, the distance between it and the image sensor increases; when the barrel objective lens 112 contracts inward, the distance between it and the image sensor decreases, thereby changing the focal length.

[0034] Exemplarily, the barrel objective lens 112 is a structure with a fixed length as Figure 3 shown, and the focal length is changed by moving; the barrel objective lens 112 can also be a structure with a variable length, and the focal length is changed by stretching or contracting its own length.

[0035] In some embodiments, the sliding signal processing device 13 includes a slide rail and a slider that matches the slide rail. Correspondingly, the sliding operation is the movement of the slider on the slide rail. As Figure 4 shown, it is a schematic diagram of an exemplary slide rail and slider. The slide rail 131 and the slider 132 are arranged on the side wall of the housing 12, and the slider 132 can move back and forth on the slide rail along the direction shown by the arrow.

[0036] In some embodiments, the sliding signal processing device 13 is a touch panel. Correspondingly, the sliding operation is the movement of an object on the touch panel, and the object can be a finger, a stylus, etc. As Figure 5The figure shows a schematic diagram of an exemplary touch panel. The touch panel 133 is disposed on the sidewall of the housing 12, and is configured to collect a sliding signal of a user moving along the direction shown by the arrow on the touch panel 133.

[0037] The touch panel 133 may specifically be a capacitive touch screen, a resistive touch screen, an optical touch screen, etc. The specific form of the touch panel 133 is not limited in the present utility model.

[0038] In some embodiments, the size of the touch panel 133 matches the size of the user's finger statistically analyzed by big data, and the shape is strip-shaped.

[0039] In some embodiments, the sliding signal processing device 13 is a gesture receiving device. Correspondingly, the sliding operation is a gesture including a preset sliding action. For example, Figure 6 The figure shows a schematic diagram of an exemplary gesture receiving device. The gesture receiving device 134 is disposed on the sidewall of the housing 12. When the gesture receiving device 134 receives a gesture including a preset forward gesture, it generates a sliding signal including a forward movement instruction; when the gesture receiving device 134 receives a gesture including a preset backward gesture, it generates a sliding signal including a backward movement instruction. In addition, if the imaging device is used in a night environment, the gesture receiving device 144 is a night vision device, such as through infrared induction recognition, low-light recognition, etc.

[0040] In some embodiments, the sliding signal processing device 13 is a voice receiving device. For example, Figure 7 The figure shows a schematic diagram of an exemplary voice receiving device. The voice receiving device 135 is disposed on the sidewall of the housing 12. When the voice receiving device 135 receives a keyword "front", it generates a sliding signal including a forward movement instruction; when the voice receiving device 135 receives a keyword "back", it generates a sliding signal including a backward movement instruction.

[0041] In some embodiments, the sliding signal processing device 13 is an eye movement tracking device. The eye movement tracking device may be integrated with the eyepiece 13. By automatically identifying the pupil distance and adjusting the barrel objective lens to protrude outward or contract inward according to the pupil distance, the finally displayed image is clearer.

[0042] It should be noted that the slide rail and slider, touch panel, voice receiving device, gesture receiving device, and eye movement tracking device provided in the above embodiments can be used in any combination, and Figures 4 to 7 The positions and shapes of the shown sliding signal processing devices are only exemplary illustrations. The specific shapes and installation positions are determined according to needs, and are not specifically limited in the present utility model.

[0043] The above-mentioned sliding signal processing device 13 receives that the user operation is a sliding operation, and adjusts the extension and retraction of the cylindrical objective lens by sliding, that is, changes the focal length of the imaging device. Compared with adjusting the focal length by rotation in the related technology, the shaking of the imaging device during the focusing process can be avoided, which not only makes the focusing more accurate, but also makes the focusing more convenient.

[0044] In some embodiments, Figure 8 As shown, the sliding signal processing device 13 further includes a driving device 136. The driving device 136 is connected to the cylindrical objective lens 112. After the sliding signal processing device 13 generates a sliding signal according to the sliding operation of the user, the driving device 136 is controlled to work according to the sliding signal, and the driving device 136 drives the cylindrical objective lens 112 to approach or move away from the image sensor 111.

[0045] The drive device 136 can be a stepper motor, a servo motor, a ball screw device, a gear rack device, etc., but the imaging device requires lightness and accurate control. In some embodiments, the drive device 136 is a linear motor.

[0046] like Figure 9 , which is a schematic diagram of a linear motor. The linear motor includes a threaded hole 1361, a smooth rod 1362 and a screw rod 1363. The linear motor is fastened to the threaded hole 121 of the housing 12 through the threaded hole 1361. Figure 3 As shown, the cylindrical objective lens 112 includes an optical hole 1121 and a threaded hole 1122 that match the linear motor, the optical rod 1362 passes through the optical hole 1122 to form a sliding fit, and the screw rod 1363 is screwed into the threaded hole 1122, so that the linear motor rotates to drive the cylindrical objective lens 112 to retract inward or protrude outward. Figure 10 , which is a schematic diagram of an imaging device including a linear motor.

[0047] Because linear motors do not require additional devices to convert rotational motion into linear motion, the structure is simplified, and the volume and weight are reduced accordingly. Linear motors can achieve direct transmission, eliminating positioning errors that may be caused by intermediate links. In addition, due to the simplified structure, linear motors have fewer parts, thereby reducing wear and maintenance requirements.

[0048] In some embodiments, the sliding signal processing device 13 further includes a linkage device. The linkage device is connected to the tubular objective lens 112 and is used to control the tubular objective lens 112 to follow the user's sliding operation, that is, to control the tubular objective lens 112 to move closer to or farther from the image sensor 111 when receiving the sliding operation. The linkage device can be a component of a mechanical structure such as a gear drive, a chain drive, a belt drive, a connecting rod mechanism, etc.

[0049] In some embodiments, the slide rail includes a plurality of limiting components, which are used to drive the barrel lens 112 to move a fixed distance when a sliding operation is received.

[0050] The linkage device moves the barrel lens 112 while the user performs a sliding operation, with a smaller time delay and a simpler internal connection compared to the driving device.

[0051] In some embodiments, as Figure 11 shown, the imaging device includes: two imaging bodies, and a connecting component 15 connecting the two imaging bodies. That is, it includes two barrel lenses 112 and an image sensor 111.

[0052] It should be noted that Figure 11 the shown housing 12 and the driving device 136 are also both two. In actual applications, the driving device 136 may or may not be present, and there can be only one driving device 136, which is used to control two barrel lenses, or there can be two, respectively used to control two barrel lenses 112; the housing 12 can be a structural member that can connect two imaging bodies simultaneously, or each imaging body can correspond to a housing 12 respectively.

[0053] In some embodiments, the connecting component 15 is movably connected to the two imaging bodies, allowing the two imaging bodies to approach or move away from each other. As Figure 12 shown, it is a front view at the angle of the eyepiece 14. The housing 12 moves inward along the arrow direction, driving the two imaging bodies to approach as a whole, and the housing 12 moves outward along the arrow direction, driving the two imaging bodies to move away as a whole. In this way, it can adapt to users with different interpupillary distances, and users can adjust according to their needs to meet their own requirements.

[0054] In some embodiments, the imaging device further includes: a clarity analysis device connected to the barrel lens 112. The clarity analysis device is used to analyze the clarity of the image collected by the imaging body and control the movement of the barrel lens 112 according to the clarity.

[0055] In some embodiments, an image quality assessment algorithm is used to determine the clarity of the first image and the second image. For example: determine the clarity of the image according to at least one of contrast, edge intensity, structural similarity, peak signal-to-noise ratio, contrast, and edge sharpness.

[0056] Exemplarily, taking the determination of the clarity of the image according to contrast, edge intensity, structural similarity, peak signal-to-noise ratio, contrast, and edge sharpness as an example, calculate the contrast, edge intensity, structural similarity, peak signal-to-noise ratio, contrast, and edge sharpness of the image, and perform normalization processing on each calculation result. The weighted sum of the normalized results is the clarity of the image.

[0057] The specific process of controlling the movement of the barrel lens 112 according to the clarity is as follows: when the clarity analysis device detects that the clarity of the image is less than the clarity threshold, it controls the barrel lens 112 to protrude or contract. During the adjustment process, the imaging main body continuously acquires images at a preset frequency, the clarity analysis device continuously analyzes the clarity of each frame of the image, and continuously adjusts until the clarity of a certain frame of the image is greater than or equal to the clarity threshold, then the autofocus is completed automatically.

[0058] In this way, when the user does not have the experience of manual focusing, the imaging device can automatically adjust the focal length according to the clarity.

[0059] In some embodiments, the imaging device further includes: a multi-modal switching device connected to the sliding signal processing device and the clarity analysis device; the multi-modal switching device is used to switch between multiple modes according to the input signal, and the multiple modes include at least one of the following groups: turn on autofocus, turn off autofocus; the moving direction of the barrel lens 112 is the same as the sliding operation direction, the moving direction of the barrel lens 112 is opposite to the sliding operation direction; the moving distance each time is a preset distance, and the moving distance each time is positively correlated with the sliding distance of the sliding operation.

[0060] The form of the multi-modal switching device can be any form such as a physical switch, a touch panel, voice control, gesture control, etc. Here, an example is given where the multi-modal switching device and the sliding signal processing device 13 are integrated together and is a touch panel.

[0061] The multiple modes include turning on autofocus and turning off autofocus. Taking the default setting as the autofocus mode (the default focus mode can also be set to the manual focus mode according to needs), and double-clicking the touch panel continuously to turn off autofocus as an example. After the imaging device is powered on, when the touch panel does not receive a double-click signal, the imaging main body acquires images, the clarity analysis device analyzes the image clarity, and judges whether the clarity is less than the clarity threshold. If the clarity is less than the clarity threshold, it controls the barrel lens 112 to protrude outward and contract inward, continuously acquires images for analysis and adjustment until the clarity is greater than or equal to the clarity threshold; if the clarity is greater than or equal to the clarity threshold, it continues to acquire images. When the touch panel receives a double-click signal, it controls the focus mode to switch to manual (the clarity analysis device stops working or no longer controls the movement of the barrel lens 112 according to the clarity). When the touch panel receives a sliding operation and generates a sliding signal, if it is determined that the sliding signal includes a forward movement signal, it controls the barrel lens 112 to protrude outward, and if it is determined that the sliding signal includes a backward movement signal, it controls the driving barrel lens 112 to contract inward.

[0062] Thus, since different users have different perceptions of clarity, in the case where the desired clarity is not achieved through autofocus, manual auxiliary focusing is performed to ensure that the images can reach the desired clarity when different users use the imaging device.

[0063] Multiple modes include that the moving direction of the barrel lens 112 is the same as the sliding operation direction, and the moving direction of the barrel lens 112 is opposite to the sliding operation direction. Taking the default setting that the moving direction of the barrel lens 112 is the same as the sliding operation direction (it can also be set by default that the moving direction of the barrel lens 112 is opposite to the sliding operation direction) and long pressing the touch panel for more than a preset duration to switch to the moving direction of the barrel lens 112 being opposite to the sliding operation direction as an example. After the imaging device is powered on, when the touch panel does not receive a long press signal and the touch panel receives a user's sliding operation, a sliding signal consistent with the user's sliding operation direction is generated. That is, if it is determined that the sliding operation is forward, the sliding signal includes an instruction to slide forward, controlling the barrel lens 112 to protrude outward; if it is determined that the sliding operation is backward, the sliding signal includes an instruction to slide backward, controlling the barrel lens 112 to contract inward. When the touch panel receives a long press signal, the moving mode of the barrel lens 112 is switched to be opposite to the sliding operation direction. When the touch panel receives a user's sliding operation, a sliding signal opposite to the user's sliding operation direction is generated. That is, if it is determined that the sliding operation is forward, the sliding signal includes an instruction to slide backward, controlling the barrel lens 112 to contract inward; if it is determined that the sliding operation is backward, the sliding signal includes an instruction to slide forward, controlling the barrel lens 112 to protrude outward.

[0064] In this way, users can flexibly set the method of adjusting the barrel lens 112 according to their own usage habits, thereby improving the user experience.

[0065] Multiple modes include that the moving distance each time is a preset distance, and the moving distance each time is positively correlated with the sliding distance of the sliding operation. The preset distance can be set differently according to different adjustment precisions. The higher the adjustment precision, the smaller the preset distance; the lower the adjustment precision, the larger the preset distance. For example, when the preset distance is 10 mm, each time it slides, the moving distance of the barrel lens 112 is 10 mm; when the preset distance is 1 mm, each time it slides, the moving distance of the barrel lens 112 is 1 mm. The conversion between the moving distance and the sliding distance can be determined according to the maximum distance that the barrel lens 112 can move when adjusting the focal length and the maximum length of the front and back slidable areas of the touch panel. For example, if the maximum distance that the barrel lens 112 can contract inward or protrude outward is 50 mm, and the maximum length of the slidable area of the touch panel is 100 mm, then the sliding distance is twice the moving distance. For example, if it slides 10 mm, the barrel lens 112 moves 5 mm.

[0066] Taking the default setting that the moving distance of the barrel lens 112 each time is a preset distance (it can also be set by default according to needs that the moving distance of the barrel lens 112 each time is positively correlated with the sliding distance of the sliding operation), and the example that the positive correlation between the moving distance of the barrel lens 112 each time and the sliding distance of the sliding operation is switched by swiping up or down. After the imaging device is powered on, when the touch panel does not receive a signal of swiping up or down, if the touch panel receives a forward or backward sliding operation of the user, it generates a sliding signal and controls the barrel lens 112 to move a preset distance. If the user needs to continue adjusting the focal length, the user can perform the forward or backward sliding operation again. When the touch panel receives a signal of swiping up or down, it switches the moving distance of the barrel lens 112 each time to be positively correlated with the sliding distance of the sliding operation. When the touch panel receives a forward or backward sliding operation of the user, it generates a sliding signal including the sliding distance and controls the barrel lens 112 to move a certain distance according to the sliding distance and the positive correlation relationship.

[0067] In this way, the user can set the moving distance of each slide according to needs, which is convenient for adapting to the needs of different users.

Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
