Description

Technical Field

[0001] The present disclosure relates to the technical field of hybrid cameras, and in particular, to a filter switching system and method for a hybrid camera. Background Art

[0002] With the progress of computer technology, machine vision has received increasing attention. To achieve machine vision, a camera is required. Currently, for a notebook computer to implement functions such as HPD (Human Presence Detection), Windows hello (a biometric authorization method), and Face ID (facial recognition), usually two cameras are equipped for the notebook computer: an RGB camera and an IR camera. Among them, the RGB camera is used for ordinary imaging, and the IR camera is mainly used to capture human face information for identifying human images, etc. Neither of them can be missing.

[0003] To save costs, there is a camera solution that combines an RGB camera and an IR camera. This camera solution is usually called a hybrid camera. The hybrid camera includes a filter. The existence of the filter is to filter out stray light that the sensor does not need and avoid the noise generated by the stray light from affecting the quality of the image.

[0004] For an RGB camera, usually a type-A IR filter (infrared filter) is used to filter out ultraviolet light and infrared light and transmit visible light. For an IR camera, usually a type-B filter is used to filter out visible light and ultraviolet light and transmit infrared light.

[0005] However, for a Hybrid camera, the problem is a bit serious. Since it is required to transmit both visible light and infrared light simultaneously, only a type-C filter can be selected. At this time, infrared light will crosstalk into the sensor of the RGB camera, affecting the imaging quality of the RGB camera, and visible light will also crosstalk into the sensor of the IR camera, affecting the imaging quality of the IR camera. This defect severely restricts the application and popularization of Hybrid cameras. Summary of the Invention

[0054] To make the purpose, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0055] Based on this, the embodiment of the present disclosure provides a filter switching system for a hybrid camera, Figure 1The structural schematic diagram of the filter switching system of the hybrid camera provided by the embodiments of the present disclosure is as follows Figure 1 As shown, the system includes:

[0056] A hybrid camera 10, a transmission module 20, a camera control module 30, and a control terminal 40;

[0057] The hybrid camera 10 includes a filter module 11. The filter module 11 includes a fully light-shielded area 111 and a plurality of filters. Among them, the types of light that each filter can pass through are different;

[0058] The camera control module 30 is respectively connected to the transmission module 20 and the control terminal 40. The camera control module 30 is used to determine whether the signal output by the control terminal 40 is an anti-peeping signal or a non-anti-peeping signal; if it is an anti-peeping signal, the camera control module 30 is further used to send a first control signal to the transmission module 20; if it is a non-anti-peeping signal, the camera control module 30 is further used to send a second control signal to the transmission module 20;

[0059] The transmission module 20 is connected to the filter module 11, and is used to control the filter module 00 to switch to the fully light-shielded area 111 according to the first control signal, or to control the filter module 11 to switch to at least one of the plurality of filters according to the second control signal.

[0060] In one embodiment, as Figure 1 shown, the hybrid camera 10 includes a substrate 12, and the substrate 12 can be a semiconductor substrate. A control trace layer 121 is provided on the substrate 12, and the control trace layer 121 can be a metal wire.

[0061] The hybrid camera 10 further includes a sensor 13 located on the substrate 12. The sensor 13 includes a first sensor 131 and a second sensor 132. In a specific embodiment, the first sensor 131 can be an RGB sensor that senses visible light, and the second sensor 132 can be an IR sensor that senses infrared light.

[0062] There is a corresponding color filter 14 on the first sensor 131 of each pixel. For example, there is a red filter on the first first sensor 131, a green filter on the second first sensor 131, and a blue filter on the third first sensor 131. It should be noted that there is no color filter on the second sensor 132.

[0063] Blocking layers 15 are formed on both sides of each color filter 14. The blocking layers 15 can serve as an isolation layer between adjacent color filters 14 or as a light-shielding function.

[0064] A plastic layer 16 is formed on the color filter 14. The plastic layer 16 serves as a transition layer to facilitate the formation of a micro lens 17 thereon.

[0065] Support layers 18 are also formed on both sides of the plastic layer 16. The support layers 18 are used to fixedly support the optical lens module 19.

[0066] The hybrid camera 10 includes a first camera and a second camera. Among them, the first camera includes a first sensor 131, a color filter 14, a micro lens 17 above the color filter 14, and a lens module 19; the second camera includes a second sensor 132, a micro lens 17 above the second sensor 132, and a lens module 19.

[0067] The hybrid camera 10 includes a filter module 11. The filter module 11 includes a fully shaded area 111 and a plurality of filters. Among them, the type of light that each filter can pass through is different.

[0068] Specifically, as Figure 1 shown, the plurality of filters include a first filter 111 and a second filter 112. Among them, the first filter 111 corresponds to the first camera, and the second filter 112 corresponds to the second camera. However, it can be understood that the plurality of filters can include more than two filters, and different types of filters can also be selected when different types of cameras are needed.

[0069] In a specific embodiment, the first camera can be an RGB camera, then the first filter 111 is an A-class IR filter, which can be used to filter ultraviolet light and infrared light and transmit visible light; the second camera can be an IR camera, then the second filter 112 is a B-class filter, which can be used to filter visible light and ultraviolet light and transmit infrared light.

[0070] In an embodiment, the camera control module 30 is respectively connected to the transmission module 20 and the control end 40. The camera control module 30 is used to determine whether the signal output by the control end 40 is an anti-peeping signal or a non-anti-peeping signal; if it is an anti-peeping signal, the camera control module 30 is further used to send a first control signal to the transmission module 20; if it is a non-anti-peeping signal, the camera control module 30 is further used to send a second control signal to the transmission module 20;

[0071] The transmission module 20 is connected to the filter module 11 and is used to control the filter module 00 to switch to the fully shaded area 111 according to the first control signal, or to control the filter module 11 to switch to at least one of the plurality of filters according to the second control signal.

[0072] In an embodiment, the system further includes: a host 50, and the host 50 is connected to the camera control module 30;

[0073] When the signal output by the control terminal 40 is a non-anti-peeping signal, the host terminal 50 is used to send a camera mode switching signal to the camera control module 30;

[0074] The camera control module 30 is used to send a second control signal to the transmission module 20 according to the camera mode switching signal.

[0075] Specifically, the control terminal 40 outputs an anti-peeping mode switching signal to the camera control module 30, and the anti-peeping mode switching signal can be any one of an anti-peeping signal or a non-anti-peeping signal. When the signal output by the control terminal 40 is an anti-peeping signal, the camera control module 30 sends a first control signal to the transmission module 20 to make the transmission module 20 switch to the full light-shielding area 111, so that the camera function of the hybrid camera cannot be used.

[0076] When the signal output by the control terminal 40 is a non-anti-peeping signal, it means that the system wants to use the camera, then the host terminal 50 sends a camera mode switching signal to the camera control module 30; the camera control module 30 sends a second control signal to the transmission module 20 according to the camera mode switching signal to make the transmission module 20 switch to at least one of multiple filters.

[0077] In one embodiment, the transmission module 20 can be a micro voice coil stepper motor, an electrified solenoid plus a magnet, etc., which can realize the device for controlling the filter module to switch.

[0078] In one embodiment, when the information of the camera mode switching signal is to use the first camera, the transmission module 20 is used to control the filter module 11 to switch to the first filter 111;

[0079] When the information of the camera mode switching signal is to use the second camera, the transmission module 20 is used to control the filter module 11 to switch to the second filter 112;

[0080] When the information of the camera mode switching signal is to use the first camera and the second camera together, the transmission module 20 is used to control the filter module 11 to switch between the first filter 111 and the second filter 112.

[0081] In one embodiment, when the filter module 11 switches to the first filter 111, the first sensor 131 collects the first optoelectronic signal and transmits it to the camera control module 30;

[0082] When the filter module 11 switches to the second filter 112, the second sensor 132 collects the second optoelectronic signal and transmits it to the camera control module 30;

[0083] The camera control module 30 is also used to process the first optoelectronic signal and / or the second optoelectronic signal and transmit it to the host terminal 50.

[0084] In a specific embodiment, for example, when the host 50 requests to enter the single - open mode of the RGB camera (the first camera), the camera control module 30 controls the transmission device 20 to switch the filter module 11 to the IR filter of type A (the first filter 111). Then, after the filter module 11 completes the switching, it sends a switching - completed signal back to the camera control module 30. Next, the camera control module 30 controls the first sensor 131 in the hybrid camera 10 to collect the first optoelectronic signal and sends it back to the camera control module 30. After the camera control module 30 processes the first optoelectronic signal, it transmits it to the host 50.

[0085] When the host 50 requests to enter the single - open mode of the IR camera (the second camera), the camera control module 30 controls the transmission device 20 to switch the filter module 11 to the filter of type B (the second filter 112). Then, after the filter module 11 completes the switching, it sends a switching - completed signal back to the camera control module 30. Next, the camera control module 30 controls the second sensor 132 in the hybrid camera 10 to collect the second optoelectronic signal and sends it back to the camera control module 30. After the camera control module 30 processes the second optoelectronic signal, it transmits it to the host 50.

[0086] When the host 50 requests to enter the dual - open mode of the IR camera and the RGB camera, the camera control module 30 controls the transmission device 20 to switch the filter module 11 between the first filter 111 and the second filter 112. Synchronously, the corresponding first sensor 131 and second sensor 132 respectively collect the first optoelectronic signal and the second optoelectronic signal and send them back to the camera control module 30. After the camera control module 30 processes the first optoelectronic signal and the second optoelectronic signal, it transmits them to the host 50.

[0087] After the host obtains the first optoelectronic signal and / or the second optoelectronic signal, it can use these optoelectronic signals to complete various functions, such as HPD, Windows hello, Face ID and other functions.

[0088] In one embodiment, when the information of the camera mode switching signal is to commonly use the first camera and the second camera, the transmission module is used to control the filter module to switch between the first filter and the second filter, including:

[0089] The first filter and the second filter are switched periodically; or,

[0090] The first filter and the second filter are switched non - periodically.

[0091] Figure 2 It is the working timing diagram when the system is in the dual - open mode. As Figure 2As shown, when the host 50 requests to enter the dual-camera mode of the first camera and the second camera, the first camera and the second camera need to be coordinated and controlled. According to the acquisition time and frequency requirements of the first camera and the second camera, data is acquired alternately. Among them, the camera control module 30 generates a clock signal. The switching of the high and low potentials of the initial clock signal is triggered by the data sent by the sensor 13 received by the camera control module 30. The switching of the start working time point of the first camera or the second camera is triggered by the transmission module 20 completing the switching and sending a switching completion signal to the camera control module 30.

[0092] The dual-camera mode of the first camera and the second camera includes two modes. Mode 1 is that the first camera and the second camera acquire data periodically. As Figure 2 shown, first, based on the filter (e.g., the first filter) switched by the current filter module, the corresponding first sensor acquires a frame of data (this is the working period of the first camera at this time). When the acquired data is transmitted to the camera control module, it triggers the switching of the high and low potentials of the clock signal. Along with the switching of the high and low potentials, it triggers the transmission module to switch the filter (e.g., switch to the second filter). After the transmission module completes the switching, it feeds back a switching completion signal to the camera control module. The camera control module controls the hybrid camera to also switch the sensor (e.g., switch to the second sensor) to acquire a frame of data. The acquired data is sent to the camera control module, and so on, periodically alternating between the first filter and the second filter.

[0093] Mode 2 is that the first camera and the second camera acquire data aperiodically. Specifically, it can be set to control the first camera and the second camera to acquire data at different frequencies. As Figure 2 shown, for example, the first camera first acquires a frame of data, and then switches to the second camera. However, the second camera can continuously acquire two frames of data without switching the filter during this period, and then switches back to the first camera. Of course, the first camera and the second camera can also acquire data at other frequencies, which can be specifically set according to actual needs.

[0094] In the present disclosure, by designing a transmission module and a filter module including a fully light-shielded area and multiple filters, and according to the signal output by the camera control module, the transmission module is controlled to switch the filter module. In this way, when a certain camera needs to be used, the filter module can be switched to the filter corresponding to the camera by the transmission module. In addition, the filter module can also be switched to the fully light-shielded area. In this way, the system can be used as an anti-peeping shutter of a camera. Through this solution, the present disclosure can effectively integrate the anti-peeping function and multiple different types of camera functions, and at the same time solve the signal crosstalk caused by the limitation of the filter in the hybrid camera, and achieve high-quality imaging.

[0095] The embodiments of the present disclosure also provide a method for switching filters of a hybrid camera. Figure 3 The flowchart of the method for switching filters of the hybrid camera provided by the embodiments of the present disclosure is as Figure 3 shown. The method includes:

[0096] Step 301: Determine whether the signal output by the control end is an anti-peeping signal or a non-anti-peeping signal through the camera control module;

[0097] Step 302: If it is an anti-peeping signal, the camera control module sends a first control signal to the transmission module;

[0098] Step 303: According to the first control signal, the transmission device controls the filter module of the hybrid camera to switch to the full-shading area;

[0099] Step 304: If it is a non-anti-peeping signal, the camera control module sends a second control signal to the transmission module;

[0100] Step 305: According to the second control signal, the transmission device controls the filter module to switch to at least one of multiple filters, where the types of light that can pass through each filter are different.

[0101] It should be noted that, as Figure 3 shown, the execution order between steps 302 and 303 and steps 304 and 305 can be swapped. For example, steps 302 and 303 can be executed first, and then steps 304 and 305, or steps 304 and 305 can be executed first, and then steps 302 and 303.

[0102] In one embodiment, if it is a non-anti-peeping signal, the camera control module sending a second control signal to the transmission module includes:

[0103] When the signal output by the control end is a non-anti-peeping signal, the host end sends a camera mode switching signal to the camera control module;

[0104] According to the camera mode switching signal, the camera control module sends a second control signal to the transmission module.

[0105] In one embodiment, the multiple filters include a first filter and a second filter;

[0106] When the information of the camera mode switching signal is to use the first camera of the hybrid camera, the filter module is controlled to switch to the first filter through the transmission module;

[0107] When the information of the camera mode switching signal is to use the second camera of the hybrid camera, the filter module is controlled to switch to the second filter through the transmission module;

[0108] When the information of the camera mode switching signal is to commonly use the first camera and the second camera, the filter module is controlled by the transmission module to switch between the first filter and the second filter.

[0110] The first filter and the second filter are switched periodically; or,

[0111] The first filter and the second filter are switched aperiodically.

[0112] In one embodiment, the method further includes: when the filter module switches to the first filter, collecting a first optoelectronic signal through the first sensor of the hybrid camera and transmitting it to the camera control module;
