Fig. 2 is a schematic diagram illustrating a method for controlling a fill-in light according to an embodiment of the present disclosure, where the method is applied to a main control chip (such as the main control chip 101 described above), and as shown in fig. 2, the method includes:
in step S11, a video stream captured by the image capturing apparatus is acquired.
The image capturing device may include various cameras, such as a monocular camera, a binocular camera, an infrared camera, and the like, which is not limited to the embodiments of the present disclosure.
In a possible implementation manner, the image capturing device may be disposed on the terminal device, that is, the terminal device may include the image capturing device; of course, the image capturing device may also be deployed independently in the actual scene, and the embodiment of the present disclosure is not limited thereto.
The image acquisition device and the main control chip can establish communication connection in a wired connection (such as an external USB line and internal circuit wiring) or wireless connection (such as a wireless network). It should be understood that the image capturing device may capture image data of an actual scene according to a preset capturing frame rate (i.e., an image capturing frequency), and transmit the image data to the main control chip in a video stream manner.
It can be known that, the acquisition frame rate of the image acquisition device is in positive correlation with the power consumption, and the lower the acquisition frame rate, the lower the power consumption, but the lower acquisition frame rate can make the time of face identification unlocking in, for example, an intelligent access control scene longer, because the lower the acquisition frame rate, the longer the exposure time. Therefore, a person skilled in the art may set an appropriate acquisition frame rate to balance the power consumption of the image acquisition device with the user requirement, and the embodiment of the present disclosure is not limited to a specific value of the acquisition frame rate of the image acquisition device.
In step S12, in a case where the preset processing procedure starts processing the currently processed frame of the video stream, the frame identification of the currently exposed frame currently exposed by the image capturing apparatus is determined.
The preset processing process may be a process for implementing a preset task, and the preset task may at least include at least one of a face recognition task and an exposure parameter calculation task.
It should be understood that technicians may pre-write algorithms for various preset tasks and deploy the algorithms in the main control chip, so that the algorithms for various preset tasks may be executed in the main control chip, that is, a preset processing process is run to process a video stream, thereby implementing various preset tasks.
As described above, the image capturing device may capture image data of an actual scene according to a preset capturing frame rate, and transmit the image data to the main control chip in a video stream manner, that is, the video stream may include multiple frames of video frames. The preset processing process starts to process the current processing frame of the video stream, which may be understood as that the preset processing process starts to use the current processing frame for operation, or that is, the preset processing process starts to use the video frame used in the current operation.
It can be understood that the current processing frame processed by the preset processing process is a video frame already acquired by the image acquisition device, or a video frame completed by the image acquisition device. The current processing frame may be a video frame that is newly acquired in the video stream, or may be a video frame that has been acquired before the newly acquired video frame, and may specifically be determined according to a processing time of a preset processing process for each frame of the video frame, a frame identifier of the video frame that is processed when the preset processing process is started, and the like, which is not limited in this embodiment of the disclosure.
It should be understood that the video frames captured by the image capture device may be provided with a frame identifier (FrameID), which may be used to characterize the capture sequence, or capture timing, of the video frames. The frame identifier may be, for example, a timestamp, a character string, a combination of a timestamp and a character string, and the like, and the embodiments of the present disclosure are not limited thereto.
The currently exposed frame currently exposed by the image capturing device may be understood as a video frame currently being shot by the image capturing device, or a video frame currently being generated by the image capturing device. It should be understood that the acquisition timing of the current exposure frame is arranged after the current processing frame.
In a possible implementation manner, a frame identifier of a currently exposed frame may be determined by acquiring a Start of frame (SOF) signal sent by the image capturing device, where the SOF signal is a timing signal sent by the image capturing device when the image capturing device starts capturing any video frame, and the SOF signal may be used to know that the image capturing device is currently exposed to a few video frames, so that the frame identifier of the currently exposed frame may be determined.
In step S13, a frame identifier of a target frame to be skipped for light supplement is determined according to the frame identifier of the current processing frame, the frame identifier of the current exposure frame, and the frame number corresponding to the single frame processing duration of the preset processing procedure, where the target frame is a video frame to be acquired after the current exposure frame.
It should be understood that the running of the algorithm is time-consuming, i.e. the pre-set processing procedure for running the algorithm is time-consuming for processing a frame of video. The preset single-frame processing duration of the processing process may be understood as a processing duration required by the preset processing process to process one frame of video frame, or an operation duration required by the preset processing process to perform an operation using one frame of video frame.
It can be understood that the single frame processing time lengths corresponding to different preset processing processes can be different; a person skilled in the art may estimate the processing time duration of a single frame corresponding to different preset processing procedures by using a method known in the art, and the embodiment of the present disclosure is not limited thereto.
In a possible implementation manner, for example, the single-frame processing duration of the preset processing process of the running algorithm may be obtained by running the algorithm corresponding to a certain preset task for multiple times through experiments in advance. Considering that, for any preset processing process, the experiment may obtain a duration set, and then the maximum duration in the duration set may be taken as the single-frame processing duration of the preset processing process; of course, the average value of the time length set can be taken, and the embodiment of the present disclosure is not limited thereto.
The frame number corresponding to the single-frame processing duration of the preset processing process may be understood as the frame number of the video frame that the image capturing device can capture during the processing of one frame of video frame in the preset processing process. For example, if the single frame processing duration of the preset processing procedure is 100ms, and the frame rate of the image capturing apparatus is 30fps, that is, approximately 33ms, to capture one frame, the number of frames corresponding to the single frame processing duration of the preset processing procedure may be at least 3 frames.
It can be known that, in the related art, the image acquisition device can send a Strobe signal to the fill light according to a preset acquisition frame rate to control the Strobe of the fill light, that is, the fill light is controlled to be turned on according to a certain frequency, so as to save the power consumption of the fill light; the preset processing process can be a video frame which does not need light supplement in practice in the process of processing a frame of video frame, for example, a video frame which is acquired latest in a video stream is acquired and processed after the preset processing process is finished processing the frame of video frame, so that a stroboscopic mode of a light supplement lamp is controlled only by sending a gating pulse signal to the light supplement lamp through the image acquisition device, the problem of electric quantity waste still exists, and the power consumption of the light supplement lamp cannot be effectively reduced.
Based on this, the number of frames corresponding to the single-frame processing duration of the preset processing process can also be understood as the number of frames of the video frame to be skipped for supplementary lighting corresponding to the preset processing process; or, the video frame acquired by the image acquisition device during processing of one frame of video frame in the preset processing process may be a video frame with the light supplement skipped.
As described above, the currently processed frame is a video frame that is processed by the preset processing process, the currently exposed frame is a video frame currently exposed by the image capturing device, and the frame identifier may represent the capturing order of the video frames. In a possible implementation manner, determining, according to a frame identifier of a currently processed frame, a frame identifier of a currently exposed frame, and a frame number corresponding to a single-frame processing duration of a preset processing procedure, a frame identifier of a target frame to be skipped for light supplement may include: updating a frame identifier set to be skipped for light supplement corresponding to a preset processing process according to the frame identifier of the current processing frame and the frame number corresponding to the single frame processing duration of the preset processing process; and determining at least one frame identifier which is sequentially arranged after the frame identifier of the current exposure frame in the frame identifier set as the frame identifier of the target frame.
As described above, the frame identification may be in the form of, for example, a timestamp, a character string, a combination of a timestamp and a character string, and the like. Wherein, according to the frame identifier of the current processing frame and the frame number corresponding to the single frame processing duration of the preset processing process, the frame identifier of the current video frame to be skipped for light supplement corresponding to the preset processing process can be determined, for example, assuming that the frame identifier adopts a timestamp form, the frame number is 2 frames, the image acquisition device acquires one frame every 20ms, and the frame identifier of the current processing frame is "time-division-second millisecond: 1202120120 ", it may be determined that the frame identifier of the currently to-be-skipped fill light corresponding to the preset processing procedure may include" 1202120140 "and" 1202120160 "; and further, the frame identifier set of the supplementary lighting to be skipped corresponding to the preset processing process can be updated according to the 1202120140 and 1202120160.
The frame identifier set of the supplementary lighting to be skipped corresponding to the preset processing process includes the determined frame identifier of the video frame to be skipped. It should be understood that the process of determining the frame identifier of the video frame to be skipped for supplementary lighting may be performed for multiple rounds, and according to the frame identifier of the video frame to be skipped for supplementary lighting determined in each round, the frame identifier currently included in the frame identifier set may be updated.
As described above, the frame identifier may represent an acquisition sequence of the video frame, and the frame identifier whose acquisition sequence is arranged after the frame identifier of the current exposure frame may be determined according to the frame identifier, so that at least one frame identifier whose acquisition sequence is arranged after the frame identifier of the current exposure frame in the frame identifier set may be used as the frame identifier of the target frame. For example, the frame identification set includes "1202120140" and "1202120160", the frame identification of the current exposure frame is "1202120140", and the frame identification of the target frame is "1202120160".
In step S14, the fill-in light of the image capture device is turned off during the period when the image capture device captures the target frame according to the frame id of the target frame.
In a possible implementation manner, controlling a fill-in light of an image capture device to turn off during a period when the image capture device captures a target frame according to a frame identifier of the target frame may include: and sending a control signal to the light supplement lamp according to the frame identifier of the target frame so as to control the light supplement lamp to be turned off during the period of acquiring the target frame by the image acquisition equipment.
In a possible implementation manner, sending a control signal to the fill-in lamp according to the frame identifier of the target frame may include: sending a closing signal to a light supplement lamp under the condition that the target frame to be exposed of the image acquisition equipment is determined according to the SOF signal; and sending a starting signal to the light supplement lamp under the condition that the image acquisition equipment finishes exposing the target frame according to the SOF signal. Through this mode, can effectively control the light filling lamp and close during image acquisition equipment gathers the target frame.
In the embodiment of the disclosure, by determining the frame identifier of the target frame to be skipped for light supplement, it is equivalent to determining the frame identifier of the video frame to be acquired without starting a light supplement lamp for light supplement; and then according to the frame sign of target frame, control the light filling lamp of image acquisition equipment and close during image acquisition equipment gathers the target frame to reduce the electric quantity consumption of light filling lamp, also realize the low-power consumption control of light filling lamp.
In one possible implementation manner, in step S13, determining a frame identifier of a target frame to be skipped for supplementary lighting according to a frame identifier of a currently processed frame, a frame identifier of a currently exposed frame, and a frame number corresponding to a single frame processing duration of a preset processing procedure, includes:
step S131: updating a frame identifier set of the light supplement to be skipped, which corresponds to a preset processing process, according to the frame number and the frame identifier of the current processing frame;
step S132: and determining the frame identifier of the target frame according to the frame identifier and the frame identifier set of the current exposure frame.
In step S131, the frame identifier set can be updated by referring to the above-mentioned manner of updating the frame identifier set according to the embodiment of the present disclosure, which is not described herein again. Step S132: determining the frame identifier of the target frame according to the frame identifier and the frame identifier set of the current exposure frame, which may include: and determining at least one frame identifier which is sequentially arranged after the frame identifier of the current exposure frame in the frame identifier set as the frame identifier of the target frame.
For example, assuming that the frame identifier is in the form of a character string, the number of frames is 3, and the frame identifier of the currently processed frame is "frame 00010009", it can be determined that the frame identifiers of the video frame to be currently skipped for supplemental lighting may include "frame 00010010", "frame 00010011", and "frame 00010012"; further, the frame identifier set of the light supplement to be skipped corresponding to the preset processing procedure may be updated, and the updated frame identifier set includes "frame 00010010", "frame 00010011", and "frame 00010012"; if the frame identification of the current exposure frame is "frame 00010011", the frame identification of the target frame is "frame 00010012".
It should be understood that the currently processed frame that the preset processing process starts to process may not be the video frame that the image capturing device has last acquired, for example, when the preset processing process starts to process the first frame of video frame, the image capturing device has acquired the fifth frame of video frame, and the number of frames is 3 frames, in this case, the frame identifiers of the groups of video frames to be skipped for supplementary lighting may be calculated according to the frame number and the frame identifier of the currently processed frame, and the first identifier set may be continuously updated. By the method, the effective frame identification of the target frame can be obtained in advance.
For example, assuming that the frame identifier is in the form of a character string, the number of frames is 3, and the frame identifier of the currently processed frame is "frame 00010009", it may be determined that the frame identifiers of a group of video frames to be skipped by the supplemental lighting include "frame 00010010", "frame 00010011", and "frame 00010012", and if the frame identifier of the currently exposed frame is "frame 00010013", it may be determined that the frame identifiers of a group of video frames to be skipped by the supplemental lighting include "frame 00010014", "frame 00010015", and "frame 00010016", that is, the frame identifier of the target frame includes "frame 00010014", "frame 00010015", and "frame 00010016".
In the embodiment of the disclosure, the frame identifier of the target frame to be skipped for supplementary lighting can be quickly determined.
As described above, the preset processing process may be a process for implementing a preset task, and the preset task may at least include at least one of a face recognition task and an exposure parameter calculation task, for example; in one possible implementation, the preset processing procedure may include: at least one of an image processing process and an exposure parameter processing process; the number of frames corresponding to a single frame processing duration of the preset processing procedure may include: at least one of a first frame number corresponding to a single frame processing duration of the image processing process and a second frame number corresponding to a single frame processing duration of the exposure parameter processing process; the currently processed frame may include: the image processing process begins processing at least one of a first video frame of the video stream and the exposure parameter processing process begins processing a second video frame of the video stream.
In a possible implementation manner, in step S131, updating, according to the frame number and the frame identifier of the currently processed frame, a frame identifier set of the light supplement to be skipped, which corresponds to a preset processing procedure, includes:
updating a first frame identification set of the supplementary lighting to be skipped, which corresponds to the image processing process, according to the first frame number and the frame identification of the first video frame; and/or updating a second frame identifier set of the light supplement to be skipped, which corresponds to the exposure parameter processing process, according to the second frame number and the frame identifier of the second video frame; the frame identification set includes at least one of a first frame identification set and a second frame identification set.
The image processing process may be used to implement a face recognition task, and the exposure parameter processing process may be used to implement an exposure parameter calculation task. In a possible implementation manner, the single-frame processing duration corresponding to the image processing process may include time consumed between the image processing process starting to process the first video frame and obtaining the image recognition result; the single frame processing duration corresponding to the exposure parameter processing procedure may include a time consumed by the exposure parameter processing procedure to start processing the second video frame to obtain the exposure parameter until the exposure parameter acts on the image capturing device.
It should be understood that, the respective single frame processing durations of the image processing process and the exposure parameter processing process may be different, and then the first frame number corresponding to the image processing process and the second frame number corresponding to the exposure parameter processing process may be different; and, the first video frame that the image processing process starts to process may also be different from the second video frame that the exposure parameter processing process starts to process.
Therefore, the first frame identification set corresponding to the image processing process can be updated according to the first frame number and the frame identification of the first video frame, and the second frame identification set corresponding to the exposure parameter processing process can be updated according to the second frame number and the frame identification of the second video frame. The first frame identifier set and the second frame identifier set may be updated by referring to the manner of updating the frame identifier sets in step S13 in the embodiment of the present disclosure, which is not described herein again.
Certainly, the first video frame which is processed by the image processing process and the second video frame which is processed by the exposure parameter processing process can also be the same frame of video frame, that is, the image processing process and the exposure parameter processing process can be designed to be executed synchronously as much as possible, that is, the same frame is used for operation at the same time as much as possible, so that the video frames for light supplement by starting the light supplement lamp can be reduced, and the power consumption of the light supplement lamp can be reduced. For example, the SOF signal sent by the image capturing device may be used to implement the synchronous execution of the image processing process and the exposure parameter processing process.
In the embodiment of the present disclosure, when the preset processing procedure includes a plurality of processing procedures, the frame identifier set can be effectively updated, so that the frame identifier of the target frame can be determined later.
As described above, the preset processing procedure includes: at least one of an image processing procedure and an exposure parameter processing procedure, the set of frame identifications including: at least one of a first frame identification set of light supplement to be skipped, which corresponds to the image processing process, and a second frame identification set of light supplement to be skipped, which corresponds to the exposure parameter processing process; in one possible implementation manner, in step S132, determining a frame identifier of the target frame according to the frame identifier and the frame identifier set of the current exposure frame includes:
determining at least one first frame identifier of a first frame identifier set, wherein the acquisition sequence of the first frame identifier set is arranged behind the frame identifier of the current exposure frame; determining at least one second frame identifier which is sequentially arranged after the frame identifier of the current exposure frame in the second frame identifier set; and determining the intersection between the at least one first frame identifier and the at least one second frame identifier as the frame identifier of the target frame.
For example, assuming that the frame identifier is in the form of a timestamp, the frame identifier of the currently exposed frame is "1202120220", the first frame identifier set includes frame identifiers "1202120220" and "1202120240", the second frame identifier set includes frame identifiers "1202120200", "120212220", "1202120240" and "1202120260", the first frame identifier includes "1202120240", and the second frame identifier includes "1202120240" and "1202120260"; the intersection between the first frame identification and the second frame identification is "1202120240", and "1202120240" may be determined as the frame identification of the target frame for which the fill-in is to be skipped.
It should be understood that the preset processing procedure may also include other procedures for implementing various preset tasks. When the preset processing process includes a plurality of processes, each frame identifier set corresponding to each preset processing process may be determined first according to the manner from step S131 to step S132 in the embodiment of the present disclosure; and then respectively determining the frame identifications arranged behind the frame identification of the current exposure frame in each frame identification set and taking an intersection to obtain the frame identification of the target frame to be skipped for light supplement.
In the embodiment of the disclosure, the frame identifier of the target frame can be determined quickly and effectively for multiple preset processing processes.
As in the fill light control device described above, the main control chip may be connected to the fill light control module, and in a possible implementation manner, in step S14, the fill light of the image capturing device is controlled to be turned off during the period when the image capturing device captures the target frame according to the frame identifier of the target frame, including:
sending a first control signal to a light supplement lamp control module according to the frame identifier of the target frame, wherein the first control signal comprises a light supplement lamp closing signal; the light supplement lamp control module is used for controlling the on-off of the light supplement lamp according to a first control signal, so that the light supplement lamp is turned off during the period that the image acquisition equipment acquires the target frame.
The first control signal may be a pulse signal, for example, a light supplement lamp turn-off signal may be set to be a low level signal, and a light supplement lamp turn-on signal may be a high level signal. In a possible implementation manner, before the image acquisition device acquires the target frame, a fill-in light lamp closing signal can be sent to the fill-in light lamp control module; and after the image acquisition equipment acquires the target frame, sending a light supplement lamp starting signal to the light supplement lamp control module.
As described above, a Start of frame (SOF) signal issued by the image capturing apparatus, which is a timing signal issued by the image capturing apparatus when capturing any video frame starts, may be acquired, and it is known that the image capturing apparatus is currently exposed to the several video frames through the SOF signal.
In a possible implementation manner, sending the first control signal to the fill light control module according to the frame identifier of the target frame may include: sending a supplementary lighting lamp closing signal to a supplementary lighting lamp control module under the condition that an SOF signal aiming at a current exposure frame sent by image acquisition equipment is acquired; and sending a light supplement lamp starting signal to the light supplement lamp control module under the condition of acquiring the SOF signal which is sent by the image acquisition equipment and aims at the last frame of target frame. By the mode, the light supplement lamp can be in the off state as far as possible during the period that the image acquisition equipment acquires the target frame, and meanwhile, the light supplement lamp can be in the on state during the period that the image acquisition equipment acquires the video frame after the target frame.
It should be noted that, the above implementation manner for sending the first control signal to the light supplement lamp according to the frame identifier of the target frame is an implementation manner provided in the embodiment of the present disclosure, and in fact, a person skilled in the art may debug the sending manner of the first control signal through multiple experiments, so that the sending timing of the first control signal meets the control requirement for the light supplement lamp, which is not limited in the embodiment of the present disclosure. For example, a fill-in light turn-off signal can be sent to the fill-in light control module under the condition that an SOF signal for a first frame target frame sent by the image acquisition device is acquired; and a supplementary lighting lamp closing signal can be started to the supplementary lighting lamp control module under the condition of acquiring the SOF signal which is sent by the image acquisition equipment and aims at the video frame acquired after the target frame.
As described above, the first control signal may be a pulse signal, for example, the fill-in lamp turn-off signal may be set to be a low level signal, and the fill-in lamp turn-on signal may be a high level signal. In a possible implementation manner, the light supplement lamp control module may control the light supplement lamp to be turned off in response to a light supplement lamp turning-off signal sent by the main control chip; and responding to a light supplement lamp starting signal sent by the main control chip, and controlling the light supplement lamp to be started.
It should be understood that, a person skilled in the art may design a logic control circuit of the fill light control module by using known digital circuit technology, and the logic control circuit controls the fill light to be turned on or off in response to the first control signal, that is, supplies power to or cuts off power from the fill light in response to the first control signal; the design of the logic control circuit is not limited in the embodiments of the present disclosure.
In the embodiment of the disclosure, by determining the frame identifier of the target frame to be skipped for light supplement, it is equivalent to determining the frame identifier of the video frame to be acquired without starting a light supplement lamp for light supplement; and then according to the frame sign of target frame, send first control signal to light filling lamp control module group, first control signal includes the light filling lamp and closes the signal, can make light filling lamp control module group control light filling lamp close during image acquisition equipment gathers the target frame to reduce the electric quantity consumption of light filling lamp, also realize the low-power consumption control of light filling lamp.
As mentioned above, the preset processing procedure comprises an image processing procedure, and the currently processed frame comprises a first video frame of the video stream, and in a possible implementation, the method further comprises:
sending a light supplement lamp closing signal to a light supplement lamp control module under the condition that an image processing process processes a first video frame to obtain an image processing result, so that the light supplement lamp control module responds to the light supplement lamp closing signal and controls a light supplement lamp to be closed; and/or sending an equipment closing signal to the image acquisition equipment so that the image acquisition equipment stops acquiring the video frame in response to the equipment closing signal; the image processing process comprises a face recognition process, and the image processing result comprises a face recognition result.
The image processing process processes the first video frame to obtain an image processing result, and can be understood as obtaining a face recognition result by running a face recognition process (namely running a face recognition algorithm and the like), wherein the face recognition process is used for realizing a face recognition task; the face recognition result may include that the face recognition is successful, that is, the identity recognition is successful, for example, the face is a registered legal face; face recognition failures, i.e., identity recognition failures, may also be included, for example, if the face is an unregistered strange face.
Under the condition of obtaining the image processing result, a fill-in light turning-off signal, such as a low-level signal, can be sent to the fill-in light control module, so that the fill-in light control module controls the fill-in light to be turned off; meanwhile, an equipment closing signal can be sent to the image acquisition equipment to close the image acquisition equipment, namely to stop acquiring video frames.
It should be understood that, after the image processing result is obtained, it may represent that the image processing task is finished, and if a new image processing task is to be triggered, that is, the image capturing device is restarted to capture a video frame, the image capturing device may be restarted and the image processing task is executed through a preset trigger condition. For example, the method can be set to be that when a user triggers a button on the intelligent access control device, the image acquisition device is started again to acquire a video frame and trigger a face recognition task; or when the infrared sensor detects that the user approaches the intelligent access control, the image acquisition equipment is started to acquire the video frame and trigger the face recognition task. The embodiments of the present disclosure are not limited to the implementation of the trigger condition.
It can be known that, image acquisition equipment can idle a few frames usually at the closing in-process, also the closing process of image acquisition equipment needs consuming time, in the embodiment of this disclosure, through sending the close signal to light filling lamp control module group and image acquisition equipment respectively, can need not to wait to close the light filling lamp after image acquisition equipment closes again, can realize closing the light filling lamp in advance, saves the electric quantity consumption of light filling lamp.
As mentioned above, the preset processing procedure includes an exposure parameter processing procedure, and the currently processed frame includes a second video frame of the video stream, where the exposure parameter processing procedure starts to process the second video frame of the video stream, and in a possible implementation manner, the method further includes:
and under the condition that the exposure parameter processing process processes the second video frame to obtain the exposure parameter, the exposure parameter is sent to the image acquisition equipment so that the image acquisition equipment acquires the video stream according to the exposure parameter.
The exposure parameter processing process processes the second video frame to obtain the exposure parameter, for example, it may be understood that an automatic exposure ae (automatic exposure) algorithm is executed according to brightness information in the second video frame to obtain the exposure parameter. The exposure parameters may include aperture size, exposure time (which may also be referred to as shutter speed), sensitivity, and the like.
In the embodiment of the disclosure, the image acquisition device can be facilitated to effectively acquire the video stream according to the exposure parameters.
Fig. 3 is a schematic diagram illustrating a method for controlling a fill-in light according to an embodiment of the present disclosure, where the method is applied to a fill-in light control module (such as the fill-in light control module 201 described above), and the fill-in light control module is connected to a fill-in light of an image capture device, and as shown in fig. 3, the method includes:
in step S21, receiving a first control signal sent by the main control chip;
in step S22, the on/off of the light supplement lamp is controlled according to a first control signal sent by the main control chip, so that the light supplement lamp is turned off during the period when the image capture device captures the target frame, where the first control signal includes a light supplement lamp turn-off signal.
As described above, the first control signal may be a signal sent by the main control chip to the fill-in light control module according to the frame identifier of the target frame. The first control signal may be a pulse signal, for example, a light supplement lamp turn-off signal may be set to be a low level signal, and a light supplement lamp turn-on signal may be a high level signal.
