Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The technical scheme disclosed by each embodiment of the application is described in detail below with reference to the accompanying drawings.
The embodiment of the application discloses image acquisition equipment, which can be image security equipment, such as an access control system. Of course, the image capturing device may also be another kind of device capable of capturing an image, such as a mobile phone, and the embodiment of the present application is not limited to the specific kind of image capturing device.
Referring to fig. 1 to 3, an image capturing apparatus according to an embodiment of the present application includes a camera 100, a housing, a light transmissive cover 200, and a hydrogel ring 600.
The housing is a base member of the image capture device and can provide a mounting location for other component members of the image capture device, either directly or indirectly, although it is also possible to provide protection for at least some of the other members.
The light-transmitting cover plate 200 is a light-transmitting protective plate, and the light-transmitting cover plate 200 is arranged on the shell and is used for covering the camera 100, so that the camera 100 is protected. The transparent cover plate 200 may be a glass cover plate or a transparent resin cover plate, and the embodiment of the application does not limit the specific material of the transparent cover plate 200. Of course, the light-transmitting cover 200 can transmit light, so that the shooting function of the camera 100 is not affected.
Of course, in the case where the image capturing apparatus includes the light filling lamp 300, the light-transmitting cover plate 200 can also cover the light filling lamp 300, and further protect the light filling lamp 300, and the light filling function of the light filling lamp 300 is not affected by the light-transmitting cover plate 200. Specifically, the light-transmitting cover plate 200 may be adhered and fixed on the housing through the first adhesive layer, or may be fixed on the housing through other manners (such as clamping), and the embodiment of the application is not limited to a specific assembly manner between the housing and the light-transmitting cover plate 200.
The camera 100 faces the light-transmitting cover plate 200, and further shooting is achieved through the light-transmitting cover plate 200. The camera 100 is mounted on the housing, and in particular, the camera 100 is fixed in the internal space of the electronic device, thereby achieving the mounting in the internal space of the electronic device.
The inside surface towards camera 100 of printing opacity apron 200 is located to water gel ring 600, and water gel ring 600 is cyclic annular structure, and water gel ring 600 encloses into the printing opacity space, and the printing opacity space is relative with camera 100, and water gel ring 600 is located the shooting visual field of camera 100 outside, and then can not influence the shooting of camera 100. Specifically, the hydrogel ring 600 may be directly disposed on the inner side surface of the light-transmitting cover plate 200, for example, the hydrogel ring 600 may be fixed on the inner side surface of the light-transmitting cover plate 200 by bonding, clamping (for example, an annular clamping groove is formed on the inner side surface of the light-transmitting cover plate 200, and the hydrogel ring 600 is clamped in the annular clamping groove), and the like. Of course, the hydrogel ring 600 may be indirectly disposed on the inner side surface of the light-transmitting cover plate 200.
It should be noted that, the hydrogel ring 600 is an annular structural member made of hydrogel, because the hydrogel has a function of absorbing water, under the condition that the ambient temperature is reduced, the temperature of the transparent cover plate 200 is reduced, the cold energy of the transparent cover plate 200 can be transferred to the hydrogel ring 600, the temperature of the hydrogel ring 600 is reduced, and then the water vapor in the environment can be absorbed, and then the air humidity is reduced, and at the same time, the hydrogel ring 600 can release heat in the process of absorbing water, so that the transparent cover plate 200 can be heated, of course, the characteristic of absorbing water and releasing heat after encountering cold of the hydrogel ring 600 is determined by the hydrogel, and the mechanism of absorbing water and releasing heat of the hydrogel is a known technology and is not described herein.
The image capturing apparatus disclosed in the embodiment of the present application improves the structure of the image capturing apparatus in the related art, and sets the hydrogel ring 600 on the inner side surface of the transparent cover plate 200, so that the hydrogel ring 600 is located outside the shooting field of view of the camera 100 and encloses a transparent space opposite to the camera 100, in which case the hydrogel ring 600 does not affect the shooting of the camera 100, and the camera 100 can shoot through the transparent space and the opposite area on the transparent cover plate 200. Under the condition of lower ambient temperature, the water vapor in the space between the camera 100 and the light-transmitting cover plate 200 can be absorbed by the water gel ring 600, and at the same time, the water gel ring 600 releases heat while absorbing the water vapor, so that the area, opposite to the light-transmitting space, on the light-transmitting cover plate 200 can be heated, and the fogging phenomenon of the area, opposite to the camera 100, on the light-transmitting cover plate 200 can be relieved well.
One of the inventive concepts for solving the technical problems of the image acquisition device disclosed by the embodiment of the application is as follows: the water gel ring 600 is arranged on the light-transmitting cover plate 200, so that the water vapor content in the space between the camera 100 and the light-transmitting cover plate 200 can be reduced under the condition that the shooting of the camera 100 is not affected, and the corresponding area of the light-transmitting cover plate 200 can be heated by heat released in the water absorption process, so that the fogging phenomenon is relieved under double pipes.
The case may include a frame 500, and the light-transmitting cover 200 may be connected to the frame 500, and in particular, the light-transmitting cover 200 may be adhered to the frame 500. Further, the image capturing apparatus according to the embodiment of the present application may further include a rear cover and a circuit board 700, and the rear cover may be connected to the frame 500, thereby forming an inner cavity of the image capturing apparatus. The circuit board 700 is disposed in the cavity. The camera 100 is mounted in the cavity and may be electrically connected to the circuit board 700.
In order to further reduce the thickness, the circuit board 700 may be provided with a hole 710, and the camera 100 is disposed in the hole 710, and this sinking installation manner is beneficial to reducing the stacking height of the circuit board 700 and the camera 100, so that the image acquisition device is thinner.
Of course, in an alternative, the image capturing apparatus disclosed in the embodiment of the present application may further include a light supplementing lamp 300, and the light supplementing lamp 300 may be directly mounted on the circuit board 700 and electrically connected to the circuit board 700. In this case, the circuit board 700 not only provides a mounting base for the light compensating lamp 300, but also supplies power to the light compensating lamp 300.
In the embodiment of the present application, the frame 500 may be provided with the first avoidance hole 510, where the camera 100 is opposite to the first avoidance hole 510 or is located in the first avoidance hole 510, so as to avoid shielding of the camera 100 by the frame 500. A gap is provided between the frame 500 and the hydrogel ring 600, so that a gap is provided between the hydrogel ring 600 and the housing. In this case, the hydrogel ring 600 has a gap with the housing, so that the hydrogel ring 600 has a sufficient water vapor exchange area, thereby achieving a better water absorption effect, and finally being more beneficial to better relieving the fogging phenomenon.
In a further alternative, the frame 500 may be provided with a receiving groove 540, the first avoidance hole 510 is formed in a bottom wall of the receiving groove 540, a notch of the receiving groove 540 faces the light-transmitting cover plate 200, the hydrogel ring 600 is disposed in the receiving groove 540 and surrounds the first avoidance hole 510, and the gap described above may be formed between the hydrogel ring 600 and an inner wall (which may include at least one of the bottom wall and the side wall of the receiving groove 540) of the receiving groove 540. In this structure, the hydrogel ring 600 can be accommodated in the accommodating groove 540 to realize a submerged installation, which can certainly improve the compactness of the assembly structure, and is also beneficial to reducing the stacking thickness, so that the image acquisition device is beneficial to design in a thinner direction. Note that, herein, the thickness direction of the image capturing apparatus may refer to a dimension of the image capturing apparatus in a direction perpendicular to the light transmitting cover plate 200. Specifically, the width of the gap between the hydrogel ring 600 and the bottom wall of the receiving groove 540 may be at least 0.5mm.
In addition, the setting of clearance can also avoid the heat that hydrogel ring 600 released to be conducted to framework 500, and then can make the heat that hydrogel ring 600 released be used for heating the corresponding region on the printing opacity apron 200 more, reaches the purpose of high-efficient heating.
The image capturing apparatus disclosed in the embodiment of the present application may further include a light supplementing lamp 300 and a heat conducting member 400. The heat conductive member 400 is provided on the inner surface of the light-transmitting cover plate 200, and the heat conductive member 400 performs a heat conductive function. In the embodiment of the present application, the heat conductive member 400 conducts heat received from one region thereof to another region. Specifically, the heat conductive member 400 may be adhered to the inner side surface of the light-transmitting cover plate 200 through the second adhesive layer, or may be fixed to the inner side surface of the light-transmitting cover plate 200 through other means.
The heat conductive member 400 is provided with a first light hole 410 and a second light hole 420, so as to allow light to pass through. The light-compensating lamp 300 and the camera 100 face the light-transmitting cover plate 200, and the camera 100 and the light-compensating lamp 300 are respectively opposite to the first light-transmitting hole 410 and the second light-transmitting hole 420. In the process of the operation of the light supplementing lamp 300, the light supplementing light emitted from the light supplementing lamp 300 can be projected to the outside of the graphic acquisition device through the second light transmitting hole 420 and the light transmitting cover plate 200, so that the light supplementing function is realized. In the working process of the camera 100, ambient light can be projected onto the lens of the camera 100 through the light-transmitting cover plate 200 and the first light-transmitting hole 410, and then pass through the lens to be finally sensed by the photosensitive chip of the camera 100 to form an image, so that the shooting function is finally realized.
The portion of the heat conductive member 400 adjacent to the second light transmitting hole 420 is at least partially located within the light supplementing view field of the light supplementing lamp 300, in other words, the portion of the heat conductive member 400 adjacent to the second light transmitting hole 420 can be irradiated when the light supplementing lamp 300 is turned on. It is known that the light compensating lamp 300 not only generates light energy in the working process, but also converts part of the light energy into heat energy, thereby increasing the temperature of the irradiated portion. In the embodiment of the application, the light-compensating light emitted by the light-compensating lamp 300 is projected to the portion of the heat-conducting member 400 adjacent to the second light-transmitting hole 420, the portion of the heat-conducting member 400 adjacent to the second light-transmitting hole 420 receives the irradiation of the light-compensating light and generates heat energy, and the heat energy is conducted to the portion of the heat-conducting member 400 adjacent to the first light-transmitting hole 410 by the heat-conducting member 400. The hydrogel ring 600 may be mounted on a surface of the heat conductive member 400 facing away from the inner side surface, the hydrogel ring 600 being disposed around the first light transmission hole 410.
In the embodiment of the present application, the heat conductive member 400 may heat a region of the light-transmitting cover plate 200 opposite to the first light-transmitting hole 410 in the case of receiving the light-compensating light emitted from the light-compensating lamp 300, thereby heating the region. Since the region of the light-transmitting cover plate 200 opposite to the first light-transmitting holes 410 can be heated, the problem of fogging of the region of the light-transmitting cover plate 200 opposite to the first light-transmitting holes 410 can be alleviated.
The image acquisition device disclosed in the embodiment of the application further adds the heat conducting member 400 on the inner side surface of the transparent cover plate 200, and makes the part of the heat conducting member 400 adjacent to the second light transmitting hole 420 at least partially located in the light supplementing view field of the light supplementing lamp 300, so that the heat conducting member 400 can generate heat energy after being irradiated by the light supplementing light of the light supplementing lamp 300, and the heat energy is conducted to the part of the heat conducting member 400 adjacent to the first light transmitting hole 410, so that the part can heat the area of the transparent cover plate 200 opposite to the first light transmitting hole 410. Since the region of the light-transmitting cover plate 200 opposite to the first light-transmitting holes 410 can be heated, the hydrogel ring 600 can be assisted to further alleviate the fogging phenomenon of the region.
In the embodiment of the present application, the heat conductive member 400 may be made of a material having good heat conductive properties. For example, the heat conductive member 400 may be a graphite sheet, or may be a structural member made of other superconducting materials (e.g., a graphene structural member). The graphite flake has the advantage of good heat conduction. In a further technical scheme, the heat conducting member 400 may be attached to the inner side surface of the transparent cover plate 200, which is advantageous for improving the installation area of the heat conducting member 400, further improving the installation stability, and improving the thermal contact area, so as to facilitate better heating of the area of the transparent cover plate 200 opposite to the second light holes 420. In order to improve the heat conduction effect, the graphite sheets can be multi-layered, and the multi-layered graphite sheets are sequentially stacked.
In a further technical solution, the frame 500 may further be provided with a second avoidance hole 520, where the light compensating lamp 300 is opposite to the second avoidance hole 520 or is located in the second avoidance hole 520, so that the light compensating light can be emitted through the second avoidance hole 520. Of course, the frame 500 is provided with the second avoidance hole 520, which is beneficial to enabling the light compensating lamp 300 to be mounted on the circuit board 700 and located in the inner cavity of the image acquisition device.
In a further technical solution, the frame 500, the camera 100, the transparent cover plate 200 and the heat conducting member 400 enclose a closed lens cavity, and the hydrogel ring 600 is disposed in the lens cavity, so that the lens cavity formed by the camera 100, the transparent cover plate 200 and the heat conducting member 400 is a smaller space, so that the hydrogel ring 600 can absorb water vapor in a targeted manner, and the water absorption load is reduced.
Because the light-compensating light of the light-compensating lamp 300 passes through the second avoiding hole 520, the heat energy generated by the light-compensating light can be transferred to the wall of the second avoiding hole 520. In order to avoid the heat energy from being transferred to the lens cavity, in the embodiment of the present application, the frame 500 may be provided with a heat insulation slot 530, and the heat insulation slot 530 may be disposed between the first avoidance hole 510 and the second avoidance hole 520. The heat insulation groove 530 is of a hollowed-out structure, so that air in the heat insulation groove 530 is not easy to conduct heat, heat insulation effect can be exerted, heat energy can be relieved from being transferred to the lens cavity due to the heat insulation effect of the heat insulation groove 530, and the lens cavity can be kept at a lower temperature, so that the liquefaction of water vapor in the lens cavity is facilitated to form liquid water to be absorbed by the hydrogel ring 600, and the dryness of the air in the lens cavity is improved.
The image acquisition device may have infrared image acquisition capabilities, based on which the camera 100 may be an infrared camera. Accordingly, the light supplement lamp 300 may be an infrared light supplement lamp. The infrared light supplementing lamp has good thermal effect, and the infrared light supplementing rays emitted by the infrared light supplementing lamp during working can be better converted into heat energy, so that the aim of better heating the heat conducting piece 400 is fulfilled.
In a specific operation, the fogging phenomenon is generally generated when the temperature difference between the lens cavity and the external environment of the image capturing apparatus is large, in other words, the light-transmitting cover plate 200 is easily fogged when the temperature of the external environment is low. In order to improve the efficiency of alleviating fog, in a preferred scheme, the image acquisition device can further comprise a power supply circuit, a temperature detection module and a control module. The power supply circuit is connected with the light supplementing lamp 300, the temperature detection module is used for detecting the ambient temperature of the external environment, the power supply circuit adjusts the current of the light supplementing lamp 300 to a first current value under the condition that the ambient temperature is smaller than a preset threshold value, and adjusts the current of the light supplementing lamp 300 to a second current value under the condition that the ambient temperature is larger than the preset threshold value, and the first current value is larger than the second current value. In this case, under the condition that the ambient temperature of the external environment is lower, the control module can actively control the power supply circuit, so that the current flowing through the light compensating lamp 300 reaches the first current, thereby improving the heat generation amount in the irradiation process of the light compensating lamp 300, and further heating the light transmitting cover plate 200 through the heat conducting member 400 more efficiently. Of course, in the case where the ambient temperature of the external environment is not so low, there is a possibility that there is no or less serious fogging, in which case the control module may control the power supply circuit such that the current of the power supply current is changed, thereby making the current of the light supplement lamp 300 small to the second current value, in which case excessive consumption of electric power can be avoided. Of course, it should be noted that, whether the current flowing through the light compensating lamp 300 is the first current or the second current, the light compensating light emitted by the light compensating lamp 300 can meet the requirement of the image capturing device for light compensation in the process of capturing the image.
Based on the image capturing apparatus disclosed in the embodiment of the present application, the embodiment of the present application discloses a control method of an image capturing apparatus, where the image capturing apparatus related to the disclosed control method is the image capturing apparatus described in the embodiment including the light filling lamp 300, please refer to fig. 4, and the disclosed control method includes:
s101, detecting the ambient temperature.
S102, controlling the current of the light supplementing lamp 300 to a first current value under the condition that the ambient temperature is lower than a preset threshold value.
And S103, controlling the current of the light supplementing lamp 300 to a second current value under the condition that the ambient temperature is higher than a preset threshold value.
S102 and S103 may be implemented by control of a control module, and specifically, the control module may control the control circuit, so that the current in the control circuit changes, and finally, the current of the light compensating lamp 300 connected in the control circuit changes. The second current value is smaller than the second current value.
The foregoing embodiments of the present application mainly describe differences between the embodiments, and as long as there is no contradiction between different optimization features of the embodiments, the embodiments may be combined to form a better embodiment, and in view of brevity of line text, no further description is provided herein.
