Description

Method for rapidly starting image acquisition, camera and storage medium

Technical Field

The present disclosure relates to the field of security monitoring technologies, and in particular, to a method for quickly starting image capture, a camera, and a storage medium.

Background

In the security monitoring field such as a home security monitoring scene, in an area where power supply is inconvenient to use, a battery camera is generally used in order to monitor the area in a picture mode. In view of saving power to the battery camera, it is common to set the functional module of the camera to an off state. The method comprises the steps that the camera is triggered to be started only when monitoring that a monitored object such as a person appears, the functional module used for collecting monitoring images or video monitoring videos in the camera can be used only when the camera is in a started state, and then the functional module is utilized to collect or record monitoring images in a monitoring area. The functional module comprises a module used for collecting monitoring images or video monitoring videos in the camera, a processor, a memory and the like of the camera. It can be understood that the more functions the camera provides, the more software and hardware resources it needs to load when starting up to implement its functions, and the longer the camera completes its startup. The starting completion time of the camera is prolonged, so that the starting time of a functional module used for acquiring monitoring images or video monitoring videos in the camera is delayed. Ideally, it is desirable that the time when the monitoring of the presence of a person is performed and the time when the camera or the functional module for monitoring image acquisition or monitoring video recording in the camera starts to acquire or record are preferably the same time, or similar times, such as times when the time difference is within a tolerable range, such as within 200 ms. The lengthening of the starting time of the camera invisibly prolongs the moment of starting to acquire or record the monitoring picture. During the prolonged time, the monitored object may generate a certain motion track, and the motion track is not successfully captured, so that the important monitoring picture is lost.

Detailed Description

The present disclosure will be described in further detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements, circuits, etc., that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.

In practical applications, there are many types of Operating systems, such as Real-time Operating systems (RTOS), windows, embedded systems (linux), Disk Operating Systems (DOS), android, and apple Operating systems. In these operating systems, if the functions of any one operating system are designed to be limited, the limited-function operating system is faster in boot speed than the more-functional or powerful operating system, compared to the powerful operating system. In the embodiment of the present disclosure, two or more operating systems are designed for a camera, and the number of functions that can be realized by designing the operating systems is more or less. The operating system which is started first can be used for enabling the functional module which is used for collecting the monitoring images or recording the monitoring videos to enter a working state capable of capturing monitoring images as soon as possible, so that the monitoring images can be captured as soon as possible. The operating system with the most functions can be used for continuously capturing the monitoring picture, and can also be used for realizing any other functions which need to be realized by the system, such as functions of face recognition, identity authentication, alarming, caching, compression, encoding, transmission and the like of people in the captured monitoring picture. Taking designing an RTOS system and a linux system as an example, generally, an RTOS system is designed to be a system with limited functions, and a linux system is designed to be a system with more functions, from the viewpoint of the speed of the starting process of the system, the starting of the RTOS system is faster than that of the linux system, compared with the linux system, the RTOS system can complete the starting at first, and the starting completion time of the RTOS system is earlier than that of the linux system, or the starting completion time of the RTOS system is earlier than that of the linux system, and the starting completion time of the linux system is later than that of the RTOS system. Compared with a powerful linux system, the RTOS system can be regarded as a small operating system, and the boot completion time of the RTOS system is usually in the order of milliseconds, such as 100 ms. The linux system can be regarded as a large system, and the start-up completion time is usually in the order of seconds.

In the embodiment of the disclosure, a functional module used for collecting monitoring images or recording monitoring videos in a camera or an implementation function of the functional module is integrated into a main chip of the camera, so that the main chip can capture monitoring pictures of a monitoring area. The method comprises the steps that at least two operation systems are installed for a camera, specifically a main chip, the main chip in a closed state is awakened under the condition that a trigger signal is obtained, all the operation systems are started simultaneously when the main chip is in an awakened state, the starting completion speed exists due to different starting completion time of different operation systems, and the main chip in the awakened state is switched to a working state under the condition that the operation system which is started firstly is started is completed. According to the sequence of the starting completion time of each operating system, the main chip performs image acquisition on the monitoring area under the sequential control of each started operating system (the main chip in the working state is sequentially controlled by each started operating system to perform image acquisition on the monitoring area), and the acquired image under each operating system is obtained. In all the operating systems, the operating system which is started firstly can quickly enable the main chip to enter a working state, and control the main chip in the working state to capture the monitoring picture at the first time, so that the time difference between the first time (the time when the moving body is monitored) and the second time (the time when the main chip starts to collect the image) is effectively shortened, the situation of losing the monitoring picture is reduced, and the recording of the monitoring picture is realized in the fastest time. The subsequent operating systems which finish the startup in sequence can control the main chip to continuously capture the monitoring pictures in sequence, so that the recorded monitoring pictures are more comprehensive. Please specifically refer to the following description for implementation of the technical solution of the embodiment of the present disclosure.

Fig. 1 is a first flowchart of an implementation of a method for rapidly starting image acquisition according to an embodiment of the present disclosure. As shown in fig. 1, the method includes:

s (step) 101, acquiring a trigger signal, wherein the trigger signal is generated when a monitored object appears in a monitored area of a camera; the main chip is in a closed state at least before the trigger signal is generated; the trigger signal can switch the main chip from an off state to an awakened state;

in this step, a trigger signal is generated and obtained when the monitored object is present in the monitored area. The monitored object may be any object that can be monitored by the camera, such as a person, animal, car, moving box, or other movable object. The monitoring of the monitoring objects mainly takes the safety of intelligent security into consideration. It is understood that the camera, in particular, different operating systems installed on the main chip in the embodiments of the present disclosure have different instruction response characteristics, such as different speeds of the boot process. Such as operating systems equipped with operating systems that can be started up most quickly (usually, the functions of the operating systems are limited, such as only the acquisition of monitoring pictures) and operating systems with powerful camera functions (image acquisition, compression, encoding, storage, angular rotation, face recognition, intercom support, remote control, etc.). The start-up procedure of powerful camera-functional operating systems is usually slow. The operating system which can be started up most quickly is installed, so that the main chip can be enabled to enter a working state at the first time under the condition that the operating system is started up, and the monitoring picture can be captured at the first time. The installation of an operating system with powerful functions is intended to achieve not only the capture of monitoring pictures but also other functions of the camera such as storage and image compression, encoding, transmission, etc.

It is understood that in the embodiments of the present disclosure, the main chip at least can implement a function of capturing an image or recording a video of the camera, or a function implemented by a functional module for capturing an image or recording a video in the camera, that is, the main chip can play a role of capturing an image or recording a video. One of the technical objectives of the embodiments of the present disclosure is: when the monitored object such as a person is monitored in the monitoring area, the main chip is enabled to enter a working state as soon as possible, so that the action track of the person in the monitoring area is captured as soon as possible.

The main chip in the embodiments of the present disclosure has three states: an off state, a wake-up state, and an on state. Normally, the main chip is in a closed state, so that the power of the camera can be saved. And under the triggering of the trigger signal, the main chip is switched from the off state to the awakened state. The awakened state may be considered as the state in which the main chip is powered on. The main chip in the embodiment of the present disclosure can capture a picture of a monitoring area on the premise that the main chip needs to enter a working state.

S102: under the condition that the main chip is in an awakened state, simultaneously starting each operating system in the at least two operating systems; wherein the starting time of each operating system is different;

here, when the main chip is woken up, the operating systems mounted thereon are started up at the same time, and because some operating systems are started up quickly, i.e., the start-up is completed quickly, and some operating systems are started up slowly, i.e., the start-up is completed slowly, the time for completing the start-up of the operating systems which start up at the same time is different. Wherein, the simultaneous start of different operating systems on the same camera can be realized based on the technology of a physical machine and a virtual machine.

S103: under the condition that the operating system which is started firstly is started, the main chip in the awakened state is switched to a working state;

here, when the operating system that has first completed booting completes booting, the main chip may enter the operating state from the awake state. The operating system which finishes the starting at first can quickly enable the main chip to enter a working state, and controls the main chip in the working state to capture the monitoring picture at the first time.

S104: and according to the sequence of the starting completion time of each operating system, the main chip carries out image acquisition on the monitoring area under the sequential control of each started operating system to obtain an acquired image under each operating system.

In this step, among the operating systems, the operating system that has completed the startup earliest first completes the startup, and the main chip can be quickly brought into a working state, and the main chip in the working state can capture the monitoring picture at the first time under the control of the operating system that has completed the startup earliest. And then under the condition that the operating system which is started secondly and early finishes starting, under the control of the operating system which is started secondly and early finishes starting, the main chip in a working state carries out image acquisition on the monitoring area. Under the condition that the operating system which finishes starting in the second and earlier stages finishes starting, the main chip in the working state performs image acquisition on the monitoring area under the control of the operating system which finishes starting in the second and earlier stages, and so on until the main chip in the working state performs image acquisition on the monitoring area under the control of the operating system when the operating system which finishes starting in the last stage finishes starting. In summary, which operating system finishes the startup, the main chip in the working state performs the capture of the monitoring picture under the control of which operating system, the plurality of operating systems sequentially control, and the main chip in the working state sequentially captures the monitoring picture, so that the operating system which finishes the startup first can control the main chip in the working state to capture the monitoring picture as early as possible, and the untimely capture of the monitoring picture is avoided as much as possible.

The execution main body of S101-S104 can be a camera, further can be a battery camera, and can be a main chip of the battery camera.

Since the main chip is controlled to capture the monitoring screen in S104, which corresponds to the operating system that has completed booting, S104 may also adopt the following description: and according to the sequence of the starting completion time of each operating system, the main chip in the working state is sequentially controlled by each started operating system to acquire images of the monitored area, so as to obtain the acquired images under each operating system.

In S101-S104, according to the characteristic that the starting completion time of different operating systems is different, the operating system which is started firstly can quickly enable the main chip to enter a working state, the main chip in the working state is controlled to capture a monitoring picture at the first time, the operating system which is started quickly is utilized to start the functional module for collecting images or recording videos, namely the main chip in the camera as soon as possible, the time difference between the first time (the time when a moving body appears is monitored) and the second time (the time when the camera starts to collect images) is effectively shortened, the situation of losing the monitoring picture is reduced, and the recording of the monitoring picture is realized in the fastest time as possible. The operating system which is started after the operating system which is started firstly can sequentially control the main chip to continuously capture the monitoring picture, so that the recording comprehensiveness of the monitoring picture is realized.

The trigger signal is generated when the monitored object is monitored in the monitoring area, and different operating systems are started simultaneously when the main chip is awakened, which is equivalent to that the different operating systems start to be started immediately when the monitored object is monitored in the monitoring area, namely, the different operating systems start to be started at the fastest reaction speed, the time difference between the first moment and the second moment is shortened invisibly, so that the main chip enters a working state from an awakened state at the fastest speed, and the monitoring of the monitoring picture is realized first when the operating system which is started first is started. The time difference from the first moment to the second moment can be effectively shortened, and the monitoring picture can be timely acquired or recorded.

Among two or more operating systems, the operating system that completes the boot earliest is usually a system with limited functions, and such an operating system can complete the boot first and make the main chip enter a working state at the fastest speed to perform the capture of the monitoring picture by the main chip. The system can realize the capture of the monitoring picture by the main chip in the shortest time, and can effectively shorten the time difference between the first time and the second time, thereby avoiding the problems that the monitoring picture cannot be captured in time and the captured monitoring picture is not captured in time due to the overlong time difference between the first time and the second time, so that the monitoring picture is lost.

Illustratively, the camera, specifically the main chip, is installed with two operating systems. Referring to fig. 2, fig. 2 is a flowchart illustrating an implementation of a method for rapidly starting image acquisition according to an embodiment of the present disclosure, where the method includes:

s201: acquiring a trigger signal, wherein the trigger signal is generated when a monitored object appears in a monitored area of a camera; the main chip is in a closed state at least before the trigger signal is generated; the trigger signal can switch the main chip from an off state to an awakened state;

s202: under the condition that the main chip is in an awakened state, starting the two operating systems simultaneously; wherein the starting time of the two operating systems is different;

s203: under the condition that the operating system which is started firstly is started, the main chip in the awakened state is switched to a working state;

for understanding the steps S201 to S203, refer to the related descriptions of steps S101 to S103, and the repeated descriptions are omitted.

S204: under the condition that the operating system with the prior starting completion time finishes starting, the main chip in a working state acquires an image of the monitoring area under the control of the operating system with the prior starting completion time; and under the condition that the operating system with the later starting completion time is started, the control right of the main chip is transferred from the operating system with the earlier starting completion time to the operating system with the later starting completion time, and the main chip in the working state carries out image acquisition on the monitoring area under the control of the operating system with the later starting completion time.

The execution main body of S201-S204 can be a camera, further can be a battery camera, and can be a main chip of the battery camera.

Wherein S204 can also be described as: under the condition that the operating system with the previous starting completion time finishes starting, the operating system with the previous starting completion time controls the main chip in a working state to acquire images of the monitoring area; and under the condition that the operating system with the later starting completion time is started, transferring the control right for controlling the main chip to carry out image acquisition from the operating system with the earlier starting completion time to the operating system with the later starting completion time, and controlling the main chip in a working state to carry out image acquisition on the monitoring area by the operating system with the later starting completion time.

In S201 to S204, in two operating systems, the operating system that is started first triggers the main chip to enter the working state as soon as possible so that the main chip in the working state records the monitoring picture at the first time, and then the operating system that is started later controls the main chip in the working state to record the monitoring picture continuously when the operating system that is started later completes the starting. Compared with the scheme that the camera in the related art is started too slowly and cannot capture the monitoring picture in time, the operating system which is started quickly enables the main chip to enter the working state as soon as possible and controls the main chip which enters the working state to capture the monitoring picture in time can avoid the problem that the camera in the related art is started too slowly and cannot acquire the image of the monitoring area in time to cause the loss of the monitoring picture. That is, in the technical scheme of the embodiment of the present disclosure, the operating system that is started first among the two operating systems is used to start the functional module for collecting images or recording videos in the camera as soon as possible, so that the time difference from the first time to the second time can be effectively shortened, and the monitoring picture can be captured in time. The situation is reduced.

Illustratively, taking the case that the camera is installed with two operating systems of RTOS and Linux,

and generating a trigger signal when the monitored object enters the monitoring area of the camera, wherein the main chip acquires the trigger signal and is in a closed state before acquiring the trigger signal. And switching from the off state to the awakened state based on the triggering of the triggering signal. When the main chip is awakened, the RTOS and the linux systems installed on the main chip are started simultaneously. Because the RTOS is designed to be an operating system with limited functions and the linux is designed to be an operating system with strong functions, the RTOS is started first, and the main chip can enter a working state from a awakened state under the control or trigger of the operating system which is started first, so that the function module for collecting images or recording videos in the camera can be started as soon as possible. When the main chip enters a working state, the started RTOS immediately controls the main chip in the working state to capture a monitoring picture (the main chip in the working state under the control of the RTOS which is started first captures the monitoring picture), so that the time difference from the moment when the monitoring object is monitored to the moment when the camera starts to collect images is shortened, and the situation of losing the monitoring picture is reduced. And in the time when the RTOS is started and the linux is not started, the RTOS controls the main chip in the working state to capture the monitoring picture. When the linux is started, the control right for controlling the main chip in the working state to acquire the image is transferred to the linux system by the RTOS system, and the linux system controls the main chip in the working state to acquire the image of the monitoring area (the main chip in the working state captures a monitoring picture under the control of the linux system which is started later). Compared with the scheme that the camera is started too slowly to acquire images of the monitored area in time in the related art, the main chip in the working state is controlled by the RTOS system started first in the time that the operating system started later is not started, so that the problem that the camera cannot acquire the monitored image in time due to too slow start in the related art can be avoided as much as possible, the time difference between the first moment and the second moment is shortened as much as possible, and the monitored image can be acquired in time.

Of course, if the hard disk space built in the camera is large enough, three or more than three operating systems are also installed to implement the scheme of rapidly starting image acquisition in the embodiment of the present disclosure, taking the three operating systems installed on the camera, specifically the main chip, including the RTOS, KURT-linux, and linux systems as an example, among the three operating systems, the designed RTOS system can implement the minimum function, the linux system can implement the maximum function, and the KURT-linux system can implement more functions than the RTOS system and less functions than the linux system. In the three operating systems, the start-up completion time is that the RTOS system is earlier than the KURT-linux system, and the KURT-linux system is earlier than the linux system. And generating a trigger signal when the monitored object enters the monitoring area of the camera, wherein the main chip acquires the trigger signal and is in a closed state before acquiring the trigger signal. And triggering the main chip to switch from the off state to the awakened state based on the trigger signal. When the main chip is awakened, the RTOS, KURT-linux and linux systems installed on the main chip are started simultaneously. Since the RTOS is an operating system with the least functions, the RTOS is started first, and the main chip can enter the working state from the awakened state under the control or trigger of the operating system which is started first. When the main chip enters a working state, the RTOS which is started first immediately controls the main chip in the working state to capture a monitoring picture so as to shorten the time difference from the moment when the monitoring object appears to the moment when the camera starts to collect images and reduce the condition of losing the monitoring picture. And in the time when the RTOS is started completely and the KURT-linux is not started completely, the RTOS controls the main chip in the working state to capture the monitoring picture (the main chip in the working state under the control of the RTOS which is started first finishes capturing the monitoring picture). And after the KURT-linux finishes starting, the control right for controlling the main chip in the working state to acquire the image is transferred to the KURT-linux system by the RTOS system, and the main chip in the working state is controlled by the KURT-linux system to acquire the image of the monitored area. And in the time that the KURT-linux system is started completely and the linux system is not started completely, the KURT-linux system controls the main chip in the working state to capture the monitoring picture (the main chip in the working state under the control of the KURT-linux system captures the monitoring picture). When the linux system is started, the control right for controlling the main chip in the working state to acquire the image is transferred to the linux system by the KURT-linux system, and the linux system controls the main chip in the working state to acquire the image of the monitored area (the main chip in the working state captures a monitoring picture under the control of the linux system). Compared with the related technical scheme, the main chip in the working state is controlled by the RTOS system which is started first to capture the monitoring picture within the time that the operating system which is started later is not started, so that the monitoring picture can be captured in time, and the situation that the monitoring picture is not captured in time is avoided as much as possible. The operating system which is started later can sequentially control the main chips in the working state to continuously capture the monitoring pictures, so that the comprehensiveness of recording the monitoring videos is realized. In addition, in the starting completion time, the KURT-linux system is used as a transition system between the RTOS and the linux system, so that the problem that the control right cannot be smoothly transferred due to the fact that the RTOS is started too fast and the linux system is too slow can be solved, and the control right of the main chip in the working state is sequentially and smoothly transferred from the RTOS to the KURT-linux system and then transferred from the KURT-linux system to the linux system.

For the above description, two or three installed operating systems are taken as an example, the number of the operating systems may also be four or more, and for the description of four or more operating systems, please refer to the description of two or three, and the repeated parts are not described again. In the embodiment of the present disclosure, it is preferable that the main chip is mounted with two operating systems or three operating systems. Of the two operating systems and the three operating systems, two operating systems are preferably installed. Therefore, the problem that the operating system installs too many cameras in response to the camera is blocked or not in time can be avoided.

In a possible implementation manner, in the case of obtaining each captured image under one operating system, the captured image obtained under the operating system needs to be cached or stored. Illustratively, a storage space is opened up in advance, and the acquired images obtained under different operating systems can be stored sequentially according to the sequence of the storage addresses in the storage space from front to back. Under the condition that the operating system with the later starting completion time is started, the operating system with the later starting completion time can read, specifically, read the acquired image obtained under the operating system with the earlier starting completion time from the storage space, control the main chip in the working state to acquire the image of the monitoring area, and cache or store the acquired image. The operating system after the start-up completion time may perform storage of the captured image under the operating system after the start-up completion time from an idle storage address adjacent to the storage address of the last frame of the captured image stored under the operating system before the start-up completion time.

It can be understood that, when the camera of the embodiment of the present disclosure is used outdoors as a device for recording a video for intelligent security, the camera, specifically, the main chip is provided with an operating system which is started first, and is intended to bring the functional module for capturing an image or recording a video into an operating state in as short a time as possible, and to capture a monitoring picture in as short a time as possible, because the operating system which is started last will be started soon after the operating system which is started first captures the picture, and will replace the operating system which is started first to capture the monitoring picture. The os that is usually started up last usually has a larger camera function, such as compression, encoding, and the like, than the os that is started up first, so that the duration of capturing the picture by the os that is started up last is usually longer than the duration of capturing the picture by the os that is started up first, as a whole from the monitoring picture capture. Since the time length of the image captured by the operating system which is finally started is longer than the time length of the image captured by the operating system which is started before, namely the image captured by the operating system which is started before is shorter, the shorter captured image has less influence on the result of analyzing whether the monitored object which appears in the monitoring area has the threat according to all captured images. Based on this, in designing the quality of the captured picture, the quality of the image captured by the camera under the operating system which is started up before can be designed to be slightly lower than the quality of the image captured by the camera under the operating system which is started up after. The image captured by the camera under the operating system which is started before can be a low-quality image, which is a relative concept, and the monitored object in the monitored area needs to be identified as a person, an animal or a vehicle at minimum. Based on this, in the embodiment of the present disclosure, the camera, specifically, the main chip, is designed to have at least two acquisition modes, the quality of the image acquired in different acquisition modes is different, and the power consumed by the camera, specifically, the main chip, in different acquisition modes is also different when the image is acquired. If the quality of the acquired image is high, the power consumption is large, and if the quality of the acquired image is low, the power consumption is small. Therefore, in practical application, the operating system can be designed to control the main chip to adopt the same acquisition mode when the main chip acquires images of the monitored area, for example, the acquisition modes are all modes for acquiring high-quality images. The main chip in the working state may also be designed to adopt different acquisition modes when the main chip performs image acquisition on the monitored area at least under the control of the two operating systems with adjacent start completion times, that is, the two operating systems with adjacent start completion times control the main chip to adopt different acquisition modes when the main chip performs image acquisition on the monitored area. The scheme adopting different acquisition modes can avoid the problem of large camera power consumption caused by the fact that high-quality acquisition images need to be acquired under all operating systems, can greatly reduce the consumption of unnecessary power, saves the electric quantity of the camera and prolongs the service life of the camera.

In the foregoing scheme, designing that the acquisition modes adopted by the cameras when the cameras are controlled by two operating systems with adjacent start completion times to acquire images of the monitored area are different includes the following situations:

the first condition is as follows: the camera, specifically the master chip, is installed with two operating systems;

in this case, in the two operating systems with adjacent start completion times, the main chip adopts a first acquisition mode to acquire images of a monitored area when being controlled by the operating system with the previous start completion time; the main chip adopts a second acquisition mode to acquire images of the monitored area when being controlled by the operating system after the starting completion time; the power consumed by the main chip when the main chip adopts the first acquisition mode to acquire the image is lower than the power consumed when the main chip adopts the second acquisition mode to acquire the image.

In case one, the design master chip includes two acquisition modes: a normal acquisition mode and a low power acquisition mode. In case one, the aforementioned first acquisition mode may be considered a low power acquisition mode. The aforementioned second acquisition mode may be considered as a normal acquisition mode. Although the quality of the image acquired in the normal acquisition mode is higher than that of the image acquired in the low-power acquisition mode, the power consumed in the low-power acquisition mode is less than that consumed in the normal acquisition mode, and the electric quantity of the camera can be greatly saved. In this case, the first acquisition mode may be an ultra-low power acquisition mode and the second acquisition mode is a normal acquisition mode. Alternatively, the first acquisition mode is an ultra-low power acquisition mode and the second acquisition mode is a low power acquisition mode.

Case two: the camera, specifically the situation that the main chip is provided with three or more than three operating systems;

under the condition, dividing all the installed operating systems into groups according to a mode of dividing two operating systems adjacent to the starting completion time into one group, and in the same group, carrying out image acquisition on a monitoring area by adopting a first acquisition mode by a main chip in a working state under the control of the operating system before the starting completion time; the main chip in a working state under the control of the operating system after the starting completion time adopts a second acquisition mode to acquire images of the monitored area; the power consumed by the main chip when the main chip adopts the first acquisition mode to acquire the image is lower than the power consumed when the main chip adopts the second acquisition mode to acquire the image.

In the aforementioned case, when three or more operating systems are divided into two groups (two adjacent operating systems are a group), the acquisition modes adopted by the main chip under the two operating systems in the same group are different, and the situation in the same group can be understood by referring to the description of the aforementioned case one. In addition to this, the following are also included: the main chip is controlled by two adjacent operating systems of the same operating system in different acquisition modes in starting completion time. Further, in the two operating systems adjacent to each other, the power consumed by the master chip when the master chip is controlled by the operating system which is started earlier than the same operating system is lower than the power consumed by the master chip when the master chip is controlled by the operating system which is started later than the same operating system. The scheme is essentially that the acquisition modes adopted by the main chip under all the operating systems are different, and the power consumed by the main chip is sequentially increased when three operating systems sequentially control the main chip according to the sequence of the previous system, the same operating system and the next system.

Taking the example that the camera is installed with three operating systems, it can also be described in the following way: the main chip adopts a first acquisition mode to acquire images of a monitored area under the control of an operating system with the start completion time being before; the main chip adopts a second acquisition mode to acquire images of the monitored area under the control of the operating system in the starting completion time; the main chip adopts a third acquisition mode to acquire images of the monitored area under the control of the operating system after the starting completion time; the power consumed by the main chip when the main chip adopts the first acquisition mode to acquire the images is lower than the power consumed when the main chip adopts the second acquisition mode to acquire the images, and the power consumed by the main chip when the main chip adopts the second acquisition mode to acquire the images is lower than the power consumed when the main chip adopts the third acquisition mode to acquire the images.

Illustratively, designing the main chip includes three acquisition modes: a normal acquisition mode, a low power acquisition mode, and an ultra-low power acquisition mode. The start-up completion time of the operating system 1 is earlier than that of the operating system 2, the start-up completion time of the operating system 2 is earlier than that of the operating system 3, and if the operating systems 1 and 2 are one group of operating systems with adjacent start-up completion times and the operating systems 2 and 3 are the other group of operating systems with adjacent start-up completion times, the acquisition modes adopted by the main chip under the two operating systems in the same group are different. When the operating system 1 controls the main chip, the main chip adopts an ultra-low power consumption acquisition mode to acquire images of the monitored area. When the operating system 2 controls the main chip, the main chip adopts a low-power-consumption acquisition mode to acquire images of the monitored area. When the operating system 3 controls the main chip, the main chip can adopt a normal acquisition mode to acquire images of the monitored area. In this case, the acquisition modes adopted by the main chip for acquiring images are different under all the operating systems, so that waste of unnecessary power consumption can be avoided, and the electric quantity of the camera can be saved. In this scenario, for two adjacent operating systems, i.e., the operating system 1 and the operating system 2, in the second case, the first acquisition mode is an ultra-low power acquisition mode, the second acquisition mode is a low power acquisition mode, and the second acquisition mode is a normal acquisition mode, that is, the acquisition modes adopted by the cameras under all the operating systems are different.

As can be seen from the solutions shown in the foregoing cases one and two, the foregoing first acquisition mode, second acquisition mode and third acquisition mode are only to illustrate that they are different acquisition modes, and do not limit each acquisition mode specifically to the normal acquisition mode, the low power consumption acquisition mode or the ultra-low power consumption acquisition mode of the camera. If similar situations occur later, please refer to the description here for understanding, and if necessary, it will be described specifically as the normal acquisition mode, the low power acquisition mode, or the ultra-low power acquisition mode.

As one implementation, the number of acquisition modes of the main chip may be designed to be the same as the number of operating systems installed on the main chip. Therefore, the monitoring picture is captured by using different acquisition modes under different operating systems. The method can save the electric quantity and can record the monitoring video in time.

It can be understood that the core component capable of realizing the image acquisition or video recording function of the camera is a camera module of the camera, and in the embodiment of the present disclosure, as shown in fig. 3, the function of the camera module or the camera module is integrated into a main chip, which mainly includes an image sensor for acquiring an image signal in a monitoring area, an amplifier for amplifying the image signal, and a converter for performing analog-to-digital conversion on the image signal; the collected image under each operating system is an image obtained by at least the collection of the image sensor, the amplification of the amplifier and the conversion of the converter. Further, the image sensor comprises a plurality of photosensitive devices for collecting the environment light signals of the monitored area and converting the environment light signals into image signals. The camera module is integrated on the main chip, so that different acquisition modes of the main chip can be realized by controlling the number of used photosensitive devices, the amplification factor of the amplifier and/or the conversion precision of the converter.

In the embodiment of the disclosure, the different capture modes of the main chip are realized based on the number of the photosensitive devices used by the main chip in image capture, the difference of the amplification factors of the amplifiers, and/or the conversion precision of the converter. The acquisition mode adopted by the main chip under the control of the first target system and the acquisition mode adopted by the main chip under the control of the second target system at least can meet one of the following conditions:

the number of photosensitive devices enabled by the master chip under the control of a first target system is less than the number of photosensitive devices enabled by the master chip under the control of a second target system; the amplification factor of the amplifier used by the main chip under the control of the first target system is lower than that of the amplifier under the control of the second target system; the conversion accuracy of the converter used by the master chip under the control of the first target system is lower than the conversion accuracy of the converter used by the master chip under the control of the second target system. When the first target system is an operating system with a starting completion time before in two operating systems with adjacent starting completion times, the second target system is an operating system with a starting completion time after; when the first target system is a previously started operating system in two operating systems adjacent to the same operating system in the starting completion time, the second target system is a later started operating system in the two operating systems adjacent to the same operating system in the starting completion time.

Specifically, in a mode in which the first acquisition mode represents that the consumed power is low and a mode in which the second acquisition mode represents that the consumed power is higher than that of the first acquisition mode, the number of the photosensitive devices which are enabled when the main chip adopts the first acquisition mode to acquire the image is less than the number of the photosensitive devices which are enabled when the main chip adopts the second acquisition mode to acquire the image; the amplification factor of an amplifier used by the main chip for image acquisition in the first acquisition mode is lower than that of the amplifier used by the main chip for image acquisition in the second acquisition mode; and/or the conversion precision of a converter used by the main chip when the main chip adopts the first acquisition mode to acquire the image is lower than that of the converter used by the main chip when the main chip adopts the second acquisition mode to acquire the image. Therefore, different acquisition modes of the main chip are realized by using the number of the used photosensitive devices, the different amplification factors of the amplifier and/or the conversion precision of the converter, the different acquisition modes can bring the beneficial effect of saving power consumption, and the effective saving of the electric quantity of the camera is realized.

As shown in fig. 4, the camera in the embodiment of the present disclosure mainly includes a microcontroller and the aforementioned main chip. The microcontroller is connected with a monitoring sensor which can be used for monitoring whether a monitored object enters a monitoring area, and the microcontroller is usually in an on state. To achieve power savings in the camera, it is desirable that the main chip be in an off state, at least until the microcontroller generates the trigger signal. And when the monitoring sensor monitors that a monitored object such as a person exists in the monitoring area, the monitoring sensor sends a notification to the microcontroller, and the microcontroller receives the notification to show that the monitoring sensor obtains a monitoring result that the monitored object enters the monitoring area. The microcontroller responds to the monitoring result to generate a trigger signal, namely the trigger signal is generated when the microcontroller obtains the monitoring result that the monitoring object enters the monitoring area, and the trigger signal is sent to the main chip by the microcontroller. The main chip is awakened under the triggering of the trigger signal. The main chip is usually in a closed state, and is only awakened or started up under the condition that a monitored object exists in a monitored area, so that the electric quantity of the camera can be greatly saved.

It will be appreciated that in some application scenarios, such as in smart home security, there may be more than one camera with the aforementioned functionality. Each camera is provided with the software and hardware resources, and the image acquisition is quickly started according to the scheme. In an application scenario with two or more cameras, the trigger signal generated by one of the cameras may be assigned, in particular sent to at least one other camera than the camera; the trigger signal assigned, in particular sent to the at least one other camera, may cause the main chips of the other cameras to switch from an off state to an awake state, at least two operating systems installed on the main chips of the other cameras being simultaneously started up while the main chips of the other cameras are in the awake state; the starting completion time of at least two operating systems on the main chips of the other cameras is different; the main chips of the other cameras can enter a working state after the first start of the operating system which is started at first is finished; and each started operating system of the other cameras can sequentially control the main chips of the other cameras to acquire images of the monitoring areas of the other cameras according to the sequence of the starting completion time of the at least two operating systems. The scheme is equivalent to that all the cameras do not need to monitor whether a monitored object exists in the monitored area of the cameras, but only one of the cameras needs to monitor whether the monitored object exists in the monitored area of the cameras, and other cameras can wake up a main chip of the cameras, enter the working state of the main chip and start all the operating systems simultaneously based on the monitoring result of one of the cameras that the monitored object exists, so that the main chip can acquire a monitoring picture at the first time by using the operating system which is started first and the other operating systems can continuously capture the monitoring picture. On the one hand, whether the other cameras monitor the monitored objects in the monitored area in charge of the cameras or not is not needed, namely, the monitoring sensors and the microprocessors of the other cameras can be in a closed state, and the electric quantity of the other cameras is greatly saved. From the whole perspective of intelligent home security, the electric quantity of most cameras is saved, the service life of the cameras can be prolonged, the electric charge expenditure is greatly reduced, and the use experience of users is improved. On the other hand, the distribution of the trigger signals among the cameras can also realize the control and acquisition of video pictures recorded by other cameras, and the diversification of the functions of the cameras is reflected. The scheme can also be regarded as a linkage scheme among multiple cameras, so that the beneficial effects of saving electric quantity and electricity charge expenditure are achieved, and the new functions of the cameras are added.

In an embodiment of the present disclosure, the method for rapidly starting image acquisition further includes: processing the collected images cached or stored under each operating system to obtain target images; wherein the target image is at least used for the camera to identify the monitored object entering the monitored area, such as analyzing whether the monitored object has safety; and/or sending the target image, wherein the target image is at least used for a receiving end receiving the target image to identify the monitored object entering the monitored area. According to the scheme, the camera can compress and encode the acquired images cached or stored under each operating system to obtain target images, the camera can analyze the target images and analyze whether the monitored objects entering the monitoring area have safety, namely, the monitored objects are self-owned or strangers; or, the target image is sent to a cloud or a server (receiving end), and the receiving end can analyze the target image and analyze whether the monitored object entering the monitoring area has safety, such as the monitored object is a person of the monitored object or a stranger. So as to realize intelligent security.

In the embodiment of the disclosure, the operating system after the start-up completion time can read the acquired image obtained by the operating system before the start-up completion time, so that the problem that the read flow is complex or the reading is easy to make mistakes due to the fact that the acquired images stored under each operating system are read one by one from the storage space when the operating system which finishes the start-up at last finishes the video recording can be avoided. In addition, because the operating system with the later starting completion time can read the acquired image obtained by the operating system with the earlier starting completion time and can store or cache the image acquired by the main control chip, after all the operating systems are started, the operating system with the last starting completion time can compress, encode and the like all the operating systems which are started before and the acquired image obtained by the operating system, and then analyze the image or send the image to the receiving end for analysis, so that the intelligent security of the home can be better realized.

The technical solution of the embodiment of the present disclosure is further described below with reference to the application scenario shown in fig. 5.

Fig. 5 shows an application scenario of home security, and it is assumed that a camera 1 and a camera 2 are respectively installed at the southwest corner and the southeast corner outside a house, and the camera 1 and the camera 2 are responsible for capturing images of respective monitored areas at respective positions. It will be appreciated that there may or may not be (partial) overlap of the monitoring areas of the two cameras, preferably there is partial overlap. The inside of each of the cameras 1 and 2 may have a composition structure as shown in fig. 3 and 4. The camera module of each camera is integrated into a respective main chip, and the main chip of the camera has the functions of image acquisition or video recording. It can be understood that the main chip in the application scene not only has the functions of image acquisition or video recording, but also has the functions of compressing, encoding, sending a target image, analyzing the image and the like. Both camera 1 and camera 2 may implement the aforementioned method of rapidly initiating image acquisition. Taking two cameras, specifically two systems of RTOS and linux are installed on main chips of the two cameras, and the acquisition mode comprises a normal acquisition mode and a low-power-consumption acquisition mode as an example,

in order to save the electric quantity of the cameras, it is assumed that before the cameras execute the flow of rapidly starting the image acquisition method, the main chips of the two cameras are both in a closed state, the microcontroller of the camera 1 is in an open (power-on) state, and the microcontroller of the camera 2 can be in a power-on state or a closed state. In view of the linkage between the cameras and in order to save power costs, it is preferred that the microcontroller of the camera 2 is in an off state. In practical application, the two systems of the RTOS and the linux are systems installed on main chips of the two cameras, the main chip can enter a working state capable of recording videos or acquiring monitoring pictures along with the completion of the start-up of the operation system which is installed on the main chip, and the main chip in the working state can start an image acquisition function to acquire or capture the monitoring pictures. The main chip is integrated with a camera module, so that the camera module has an image acquisition function or a video recording function. Besides, the main chip also has other core functions of the camera, such as storage, compression, encoding and the like. Specifically, the other core functions of the master chip can be set according to actual conditions.

Because the main chip can capture the monitoring picture only when being in the working state, and the main chip is in the closed state such as the shutdown state under the normal condition, the time from the shutdown state to the startup and entering the working state of the main chip can be shortened as much as possible by utilizing the subsequent technical scheme. Since the shorter this time, the less video will be lost from the time the monitoring object is detected to the start of recording. The following shows the technical scheme in the application scene:

the microcontroller of the camera 1 is in an on state, and the monitoring sensor of the camera 1 connected with the microcontroller monitors whether a monitored object such as a person appears in a monitoring area in charge of the camera 1. When the monitoring sensor detects the presence of a person, the monitoring sensor sends a notification message to the microcontroller of the camera 1, and the microcontroller receives the notification message to indicate that the monitoring sensor obtains a monitoring result indicating that a monitored object enters a monitored area. The monitoring sensor can be independently arranged in the camera 1 independently of the microcontroller and the main chip, can be arranged in the microcontroller, and can integrate the functions of the monitoring sensor into the microcontroller, which is specifically determined according to the actual use condition. The monitoring sensor may be any reasonable sensor capable of detecting the presence of a moving body, such as a person, such as an infrared or near infrared sensor, a proximity sensor, a sound sensor, a radar laser, etc.

The microcontroller generates a trigger signal in response to the notification message and sends it to the main chip of the camera 1, which is awakened based on the triggering of the trigger signal. In case the main chip is woken up, the two operating systems installed thereon are started up simultaneously. In two operating systems, namely an RTOS and a linux, the RTOS is started quickly, the starting completion time is usually in the millisecond level, the linux system is started slowly, and the starting completion time is usually in the second level. The RTOS system can rapidly initialize system components, the RTOS operating system finishes starting firstly, the main chip enters a working state, and the RTOS controls the main chip to execute the control right of the image acquisition function firstly. Under the RTOS system, the main chip entering the operating state immediately captures images of people appearing in the monitoring area of the camera 1 to capture a monitoring picture at the first time, and caches or stores the captured images in a preset storage space. Compared with an RTOS system capable of being started quickly, the linux system has the powerful functions which are not provided by the RTOS, such as compression, image coding, talkback supporting and remote control, so that the linux system is started slowly, and in the time that the RTOS is started first but the linux is not started completely, the RTOS controls the main chip to capture the motion trail of the person. Compared with linux, RTOS finishes starting at first and controls the main chip in a working state to acquire images in the fastest time, so that the time of the main chip from a shutdown state to a startup state and entering the working state is effectively shortened, the acquisition of monitoring pictures is achieved in time, and the loss of the monitoring pictures is reduced. And under the condition that the linux is started, the RTOS operating system releases the control right for executing the image acquisition function on the main chip, and the linux system reads the images cached or stored in the RTOS system, controls the main chip to continuously acquire the images of the motion track of the monitored object and caches the acquired images. The simultaneous start of the two operating systems in the main chip can be realized based on the technology of a physical machine and a virtual machine, the transfer of the control right relates to data interaction between the two operating systems, and the interaction process can also be realized based on the technology of the physical machine and the virtual machine.

Exemplarily, it is assumed that an image captured under an RTOS system may be stored in a frame form and stored to a storage space having a storage address of 0x00-0x1 f; images acquired under the linux system may be stored starting from a free address adjacent to the storage address 0x1f, such as 0x 20. In practical applications, the image may be stored frame by frame in the form of a queue or a stack. The linux system is used for reading the images cached or stored under the RTOS system and caching the acquired images obtained under the operating system of the linux system, aims to smoothly integrate the images cached or stored under the RTOS system and the images acquired under the linux system, and avoids the problems that the reading process is complex or the reading is easy to make mistakes due to the fact that the acquired images stored under the operating systems are read one by one from the storage space. Compared with the images acquired under the linux system, the set of the images under the two operating systems can reflect the comprehensiveness of the monitored images, and is more favorable for accurately identifying the monitored object, such as identifying whether the person appearing in the monitored area is a self-owned person or a stranger. Under a linux operating system, the collected images can be compressed, encoded and the like according to a certain image processing standard, such as an h.264 or h.265 standard, so as to obtain a target image, and the target image is analyzed. Illustratively, whether a monitored object entering the monitored area has safety is analyzed according to the target image. Or, the target image is sent to a cloud or a server, and the cloud or the server analyzes the target image, for example, whether the monitored object entering the monitored area has security, such as a self-owned person or a stranger, is analyzed, so as to realize intelligent security. If the master chip is analyzed to find out that the person is a stranger, the master chip can generate an alarm signal to prompt the master that the stranger enters. Wherein, AI (artificial intelligence) algorithm can be used to identify whether the monitored object is a person of the house or a stranger.

It can be understood that, in the embodiment of the present disclosure, a system that is started later, such as a linux system, may not only continue to control the main chip to capture the picture in the monitoring area by the RTOS system that is started earlier, but also perform a series of processes, such as security analysis, alarm generation, and transmission of the monitoring picture to the cloud, based on the monitoring pictures obtained under all the operating systems. Therefore, in two operating systems installed on the main chip, the small system RTOS system is a system set for enabling the main chip to quickly enter a working state, and a system really playing the functions of analyzing, alarming, transmitting and the like on images is a large system linux system. Of course, the large system-linux system may implement not only the several functions described above, but any other desired functions that the operating system is capable of. In the application scenario, the RTOS system can only provide limited functions of controlling the main chip to capture pictures, caching captured pictures, and the like, while the linux system can provide functions of controlling the main chip to capture pictures, caching captured pictures, and can also provide compression, coding and other necessary functions, so that the RTOS system is considered as a small system and the linux system is considered as a large system in the scheme. Compared with the scheme in the related technology, the application scene utilizes the dual systems to effectively shorten the time from the shutdown state to the startup state and enter the working state of the main chip, and timely captures the monitoring picture. In a popular way, the technical solution in the embodiment of the present disclosure can be regarded as a solution for implementing a fast start of an image capturing function of a camera by using a dual system.

In the application scenario, in order to reduce the consumption of the electric quantity of the camera, the linux operating system can obtain the control right of the main chip to realize the continuous capture of the monitoring picture shortly after the RTOS operating system starts to capture the picture, so that the requirement on the quality of the image acquired by the RTOS operating system can be slightly lower than that acquired by the linux operating system. The image quality includes at least one of image color, sharpness, resolution, amount of detail information, and the like. But it is also required to stipulate in advance that the judgment on whether the monitored object is a person, an animal or a vehicle cannot be influenced at least by the low-quality image. In practical applications, the main chip of the camera can be designed to have two acquisition modes, which are the same as the number of operating systems installed on the main chip: a normal acquisition mode and a low power acquisition mode. Under the RTOS operating system, the main chip can adopt a low-power consumption acquisition mode to capture a monitoring picture. Under the linux system, the main chip can capture a monitoring picture in a normal acquisition mode. Compared with the scheme that the main chips of the two operation systems adopt the normal acquisition mode to capture the monitoring picture, the main chips of the different operation systems adopt different acquisition modes to capture the image, so that the power consumption can be effectively saved, and the unnecessary consumption of electric quantity is reduced.

In the application scene, different acquisition modes are realized by controlling the number of the photosensitive devices used by the main chip, the amplification factor of the amplifier and/or the conversion precision of the converter. Specifically, the image sensor may be designed to include M rows and N columns of photosensitive devices, where M, N are all positive integers greater than 1. All the photosensitive devices (M × N photosensitive devices) in the image sensor can be used for collecting the ambient light signal of the monitored area and converting the ambient light signal into an image signal; and may also be used in part to collect ambient light signals from the monitored area and convert the ambient light signals into image signals. The use of the entire photosensitive device results in a higher image quality, but consumes more power, than if the photosensitive device were partially used. In the application scenario, a part of photosensitive devices can be enabled to collect and convert the ambient light signals under the RTOS, and all photosensitive devices can be enabled under the linux operating system or more photosensitive devices can be enabled to collect and convert the ambient light signals than under the RTOS. Illustratively, the RTOS operating system has 2/3 × M × N photosensitive devices enabled under it, the linux operating system has M × N photosensitive devices enabled under it, or 4/5 × M × N photosensitive devices enabled under it. The control of the number of the photosensitive devices is equivalent to the control of the photosensitive proportion of the image sensor, and different acquisition modes can be realized by acquiring the ambient light signals according to different photosensitive proportions. The photosensitive devices are enabled more, and the photosensitive proportion is large; the photosensitive devices are less in use and the photosensitive proportion is small. The quality of an image taken with a large exposure ratio is better than that taken with a small exposure ratio, but a large exposure ratio consumes more power than a small exposure ratio. Different collection modes can be realized by controlling the number of the photosensitive devices, and the electric quantity of the camera can be effectively saved. In practical application, balance can be made between image quality and sensitization proportion according to the actual service condition to satisfy the quality demand of image, still satisfy the demand of saving the electric quantity.

Typically, the amplification of the amplifier is in a range of values from a minimum value to a maximum value, illustratively, 2-20. In the application scenario, the amplification factor used by the amplifier under the RTOS operating system can be designed to be smaller than that used under the linux operating system. The larger the magnification, the better the quality of the image, but the more power it consumes. Illustratively, the amplifier is amplified using the minimum amplification factor under the RTOS operating system and the maximum amplification factor under the linux operating system. Alternatively, the amplifier under the RTOS operating system was amplified using 1/3 for maximum amplification and the amplifier under the linux operating system was amplified using 2/3 for maximum amplification. Different acquisition modes can be realized by controlling different amplification factors, and the electric quantity of the camera can be effectively saved.

The conversion accuracy of a converter in general, and particularly a converter from analog to digital (AD converter), can take at least two of the following discrete values, such as 0.1, 0.01, 0.001, 0.0001, etc. In the application scenario, the accuracy of the converter under the RTOS system can be designed to be lower than that of the converter under the linux system. Illustratively, the accuracy used by the RTOS system downconverter is 0.1, and the accuracy used by the linux system is 0.0001. Alternatively, the accuracy used by the RTOS system down-converter is 0.01 and the accuracy used by the linux system is 0.001. Different acquisition modes can be realized by controlling different conversion precisions, and the electric quantity of the camera can be effectively saved.

In the above scheme, the main chip is provided with two operating systems, i.e., an RTOS system and a linux system, where the main chip captures a picture in a low-power-consumption acquisition mode when the RTOS controls the main chip, and captures a picture in a normal acquisition mode when the linux controls the main chip, if the main chip is provided with the three operating systems, i.e., the RTOS system, the KURT-linux system and the linux system, the start completion time of the RTOS system is earlier than that of the KURT-linux system, and the start completion time of the KURT-linux system is earlier than that of the linux system, and a specific process for continuously completing the monitoring picture capture under each operating system is described in the foregoing related description, which is not repeated. If the main chip adopts the ultra-low power consumption acquisition mode to capture pictures when the RTOS controls the main chip, adopts the low power consumption acquisition mode to capture pictures when the KURT-linux controls the main chip, and adopts the normal acquisition mode to capture pictures when the linux controls the main chip, the number of the enabled photosensitive devices is sequentially increased in the sequencing of the ultra-low power consumption acquisition mode, the low power consumption acquisition mode and the normal acquisition mode, the amplification factor of the amplifier is sequentially increased, and the conversion precision of the converter is sequentially improved. Illustratively, the RTOS system enables 1/3 × M × N light sensing devices for the master chip when controlling the master chip, the KURT-linux system enables 2/3 × M × N light sensing devices for the master chip when controlling the master chip, and the linux system enables M × N light sensing devices for the master chip. The amplification factor of the amplifier is 1/3 × the maximum amplification factor when the RTOS system controls the main chip, the amplification factor of the amplifier is 2/3 × the maximum amplification factor when the KURT-linux system controls the main chip, and the amplification factor of the amplifier is the maximum amplification factor when the linux system controls the main chip. The conversion accuracy of the converter is 0.1 when the RTOS system controls the main chip, 0.01 when the KURT-linux system controls the main chip, and 0.001 when the linux controls the main chip. The above numerical values are merely specific examples and are not limited to all manner of the embodiments of the present disclosure. The design of the battery camera can greatly save the electric quantity of the camera and prolong the service time of the battery camera. A brand new scheme is provided for saving the electric quantity of the battery camera.

In an application scene that the main chip is provided with two operating systems, the microcontroller and the main chip of the camera 2 which can be linked with the camera 1 are both closed, a trigger signal generated by the microcontroller of the camera 1 can be sent to the camera 2, particularly the main chip of the camera 2, and the main chip is awakened based on the trigger of the trigger signal. The two operating systems mounted thereon are simultaneously started up with the main chip of the video camera 2 in a state of being woken up. The RTOS operating system of the main chip of the camera 2 is started first, the main chip is enabled to enter a working state, the RTOS controls the main chip to execute the control right of the image acquisition function first, and the main chip is controlled to acquire the monitoring images in the monitoring area of the camera 2 and store the acquired images. Under the condition that the linux system of the main chip of the camera 2 is started, the RTOS system releases the control right for executing the image acquisition function on the main chip, the linux system reads the images cached or stored in the RTOS system, controls the main chip to continuously acquire the images of the motion track of the monitored object in the monitoring area of the camera 2, and caches the acquired images. With the triggering of the triggering signal of the camera 1, the camera 2 does not need to monitor whether a monitored object exists in a monitored area which is in charge of the camera 2, and if the monitored object exists, a monitoring sensor and a microprocessor of the camera 2 are in a closed state under the normal condition, so that the electric quantity of the camera 2 is greatly saved. From the overall perspective of intelligent home security, most of the cameras save electric quantity, the service life of the cameras can be prolonged, and the expenditure of electric charge is reduced. Because data interaction exists between the cameras 1 and 2 in the application scene, such as sending and receiving of the trigger signal, and the camera 2 can wake up the main chip of the camera based on the trigger signal sent by the camera 1 and quickly enter a working state to realize timely acquisition of a monitoring picture, the scheme can be regarded as a linkage scheme among multiple cameras, and the linkage scheme has the beneficial effect of saving electric quantity and electricity charge expenditure.

Fig. 6 illustrates a time comparison diagram given by a scheme for starting the image capturing function of the camera by using the related art (referred to as a related scheme for short) and a scheme for realizing the quick start of the image capturing function of the camera by using the dual system (referred to as a scheme for starting by using the dual system for short) provided by the embodiment of the disclosure. In fig. 6, it is assumed that the trigger signals in both schemes are generated at the same time, i.e. the presence of a person in the monitored area is monitored at the same time. It is assumed that the boot completion time of the related scheme is the same as that of the post-operating system in the dual system. Based on the above assumptions, the following conclusions can be drawn from fig. 6: compared with the first scheme, the scheme of rapidly starting acquisition by using the dual systems can effectively shorten the time from the shutdown state to the startup state and entering the working state of the main chip. The shortening of the time can effectively reduce the time difference from the first time (the time when the moving body is monitored) to the second time (the time when the camera starts to collect images), for example, the time is shortened from t1 to t1-t2, so that the recording of the monitoring picture is realized in the fastest time, and the reduction of the condition of losing the monitoring picture is realized.
