Detailed Description
Hereinafter, exemplary embodiments of the present application will be described with reference to the accompanying drawings. Well-known functions or constructions are not described in detail for clarity and conciseness because they would obscure the application in unnecessary detail. Terms described below, which are defined in consideration of functions in the present application, may be different according to intentions or implementations of users and operators. Therefore, the terms should be defined based on the disclosure of the entire specification.
Briefly, the present application relates to an image pickup apparatus, a method of reducing power consumption of the image pickup apparatus. By reducing the standby power consumption of the camera system, the purpose of prolonging the endurance time of the camera device is achieved.
Referring to fig. 1, a schematic structural diagram of an embodiment of an image capturing apparatus provided in the present application is shown. The image pickup apparatus 10 and the correspondent node 20 are connected by wire or wireless.
Optionally, the communication peer may be a router, a base station host, a mobile terminal, or a PC, and all devices that can communicate with the camera device may be used as the communication peer.
In the present embodiment, the image pickup apparatus 10 includes a first communication module 11, a second communication module 12, and a first processor 13.
The first communication module 11 and the second communication module 12 are used for data interaction with the correspondent node 20. Wherein, the power consumption of the first communication module 11 is less than the power consumption of the second communication module 12.
The first processor 13 is configured to switch to the first communication module 11 when a communication requirement for the image pickup apparatus 10 to send data to the correspondent node 20 is lower than a preset condition, and switch to the second communication module 12 when the communication requirement for the image pickup apparatus 10 to send data to the correspondent node 20 is higher than or equal to the preset condition.
For example, when the image pickup apparatus 10 does not start any communication module (for example, immediately after power on), the first communication module 11 is started when the communication request for the image pickup apparatus 10 to transmit data to the correspondent node 20 is lower than the preset condition, and the second communication module 12 is started when the communication request for the image pickup apparatus 10 to transmit data to the correspondent node 20 is higher than or equal to the preset condition. When the camera device 10 has started the first communication module 11, switching the first communication module 11 to the second communication module 12 when the communication requirement that the camera device 10 sends data to the correspondent node 20 is higher than or equal to a preset condition; when the camera device 10 has started the second communication module 12 and the communication requirement of the camera device 10 for sending data to the correspondent node 20 is lower than the preset condition, the second communication module 12 is switched to the first communication module 11.
Optionally, the first communication module 11 and the second communication module 12 perform data interaction with the correspondent node 20, which may specifically be: the first communication module 11 or the second communication module 12 may send the operating state information of the image pickup apparatus 10, such as the operating mode, the power level, and the signal connection strength between the image pickup apparatus 10 and the correspondent node 20, to the correspondent node 20, or the first communication module 11 or the second communication module 12 may send the shot video to the correspondent node 20, or the first communication module 11 or the second communication module 12 may receive the instruction sent by the correspondent node 20. The instruction may include an instruction for controlling the camera 10 to turn on and off, and an instruction for controlling the camera 10 to adjust the shooting parameters; the shooting parameters may be a focal length, brightness, contrast, and the like of the image pickup device 10.
Optionally, in a specific embodiment, the communication requirement when sending data may specifically be: sending the data total amount of the image video stream, or checking the data code stream size in real time when monitoring the image, or adjusting the parameters of the camera device and setting the mode of the camera device; such as the definition and fluency of real-time images, the remote upgrading of the application system of the camera device or the upgrading of the control algorithm of the sensor, etc.
Alternatively, in another embodiment, the communication requirement when sending data may also be determined according to the operation mode of the camera device 10, and it is understood that the camera device 10 may include a plurality of operation modes, such as a standby mode, a monitoring mode, a data interaction mode, a live image mode, and the like. In a specific operation, if the camera device 10 is in a standby mode or a monitoring mode, the first processor 13 switches the communication module of the camera device 10 to the first communication module 11 with lower power consumption; if the camera device 10 is in the data interaction mode or the live image mode, the first processor 13 switches the communication module of the camera device 10 to the second communication module 12 with higher power consumption and better data transmission performance.
It can be understood that the communication requirement for the camera device 10 to send data to the correspondent node 20 is lower than the preset condition, and the communication requirement for general data interaction between the camera device 10 and the correspondent node 20 can be completely satisfied by using the first communication module 11 with lower power consumption.
Optionally, in another specific embodiment, the first processor 13 is configured to implement switching of the communication module according to a received instruction sent by the correspondent node 20, and different instructions may correspond to different communication requirements. For example, the communication requirement corresponding to the first instruction is higher than or equal to the preset condition, and the communication requirement corresponding to the second instruction is lower than the preset condition, the camera device 10 switches to the second communication module 12 when receiving the first instruction sent by the correspondent node 20, and switches to the first communication module 11 when receiving the second instruction sent by the correspondent node 20.
It can be understood that, in an embodiment, the communication requirement does not refer to the type of the transmitted data, but refers to one of the total data amount of the transmitted video stream, the data stream size when the monitoring image is viewed in real time, or the response speed of the camera device when the camera device is subjected to parameter adjustment and mode setting, for example, when the amount of the transmitted video data is small or the transmission speed requirement is low, the first communication module 11 may still be used for data interaction.
For example, the camera device 10 is in a monitoring mode, that is, the camera device 10 automatically turns on the camera component at regular time or periodically turns on the camera component to capture images. At this time, the image definition and the communication requirement for transmitting the image data code stream are lower than the preset conditions, and the image pickup apparatus 10 communicates with the correspondent node 20 through the first communication module 11. When the user views the live image, the communication requirement that the camera device 10 sends data to the correspondent node 20 is higher than the preset condition, and the camera device 10 sends the live image to the correspondent node 20 through the second communication module 12 and performs communication.
Optionally, the first processor 13 may also be connected to a sensor, and the camera device 10 further includes a camera assembly. The sensor may be an infrared sensor for detecting the presence of organisms in the environment. The infrared sensor detects that organisms appear in the environment, transmits the feedback signal to the first processor 13, and the first processor 13 starts the camera assembly and switches to the second communication module 12, and sends a real-time image to the communication opposite terminal 20 through the second communication module 12. Meanwhile, the first processor 13 also sends an alarm signal to the correspondent node 20 through the first communication module 11 or the second communication module 12.
Optionally, the camera assembly includes a camera and a second processor. The camera is used for shooting images, and the second processor is used for starting the camera and processing the images when receiving a third instruction sent by the first processor 13, and sending the processed images to the correspondent node 20 through the first communication module 11 or the second communication module 12; or when receiving a fourth instruction sent by the first processor 13, the camera is turned off.
The third instruction is sent by the first processor 13 to the second processor when the sensor detects that a biological body appears in the environment or receives a first instruction sent by the correspondent node 20 for image retrieval, and the fourth instruction is sent by the first processor 13 to the second processor when the sensor detects that the biological body in the environment disappears or receives a second instruction sent by the correspondent node 20 for image retrieval ending.
Optionally, the first processor 13 and the second processor may be a Micro Controller Unit (MCU) and a Central Processing Unit (CPU) that are separately arranged, where the Central Processing Unit is mainly used for Processing an image captured by the camera, and the micro control Unit is responsible for executing control logic. Namely, the micro control unit is used for receiving the feedback signal from the sensor and the instruction of the communication opposite terminal 20, so as to switch the first communication module 11 or the second communication module 12. The second processor processes the image captured by the camera and sends the image to the correspondent node 20 through the first communication module 11 or the second communication module 12.
The first processor 13 and the second processor may also be integrated together in a System On Chip (SOC) that may contain the above-mentioned functions of both the first processor 13 and the second processor. In addition, the existing communication module usually includes a processor, for example, the processor built in the sub-1G can execute the control logic of the micro control unit MCU, that is, the first communication module 11 or the second communication module 12 of the camera device 10 is switched by the built-in processor of the communication module to maintain data interaction with the correspondent node 20.
Optionally, the first communication module 11 may adopt any one of Zigbee, Z-WAVE or SUB-1G, and the second communication module 12 is a WiFi module.
The working frequency band of the first communication module 11 may be any one of 433MHz, 868MHz, 915MHz, 920MHz, and 2.4 GHz.
Optionally, when the second communication module 12 is a WiFi module, the camera device 10 further obtains the service set identifier, the WiFi connection password, and the channel information that are WiFi-connected to the communication peer 20 through the first communication module 11, so that when the camera device 10 enables the second communication module 12 (i.e., the WiFi communication module), the WiFi connection is formed with the communication peer 20.
It is understood that, in an embodiment, after the camera device 10 is started, the camera device 10 maintains data interaction with the correspondent node 20 through at least one communication module.
Unlike the prior art, the imaging apparatus disclosed in the present embodiment includes: the first communication module and the second communication module are used for carrying out data interaction with a communication opposite terminal; the power consumption of the first communication module is less than that of the second communication module; the first processor is used for switching to the first communication module when the communication requirement that the camera device sends data to the communication opposite end is lower than a preset condition, and switching to the second communication module when the communication requirement that the camera device sends data to the communication opposite end is higher than or equal to the preset condition. Through the mode, the communication modules with different power consumptions can be selected according to the communication requirements in the data interaction process, and the communication requirements for performing data interaction by the camera device for most of time are low. Therefore, the camera device is switched to the first communication module with low power consumption when the data interaction communication requirement is low, the power consumption of the camera device is effectively reduced, and the endurance time of the camera device is prolonged.
Referring to fig. 2, a schematic structural diagram of another embodiment of the image capturing apparatus provided in the present application is shown.
The camera device 10 includes a first communication module 11, a second communication module 12, a first processor 13, a camera assembly 14, a sensor 15, and a battery assembly 16.
The camera device 10 maintains data interaction with the correspondent node 20 through the first communication module 11 and the second communication module 12, the camera assembly 14 is used for taking and processing images, the sensor 15 is used for detecting whether organisms appear in the environment, and the battery assembly 16 is used for supplying power to the whole device.
Specifically, the sensor 15 is used for detecting whether a living organism is present in the environment, and the sensor 15 sends a corresponding feedback signal to the first processor 13 when the living organism is detected to be present in the environment or the living organism in the environment is detected to disappear.
In this embodiment, the first processor 13 is specifically configured to, when the sensor 15 detects that an organism appears in the environment or receives a first instruction sent by the correspondent node 20 for invoking a monitoring picture, activate the camera assembly 14 and switch to the second communication module 12, and send the image to the correspondent node 20 through the second communication module 12.
The first processor 13 is further specifically configured to turn off the camera assembly 14 and switch to the first communication module 11 when the sensor 15 detects that the living body in the environment disappears or receives a second instruction sent by the correspondent node 20 to finish retrieving the monitoring screen.
In one scenario, the correspondent node 20 sends a first instruction to the camera device 10 to call a real-time monitoring image, and after receiving the first instruction, the camera device 10 starts the camera assembly 14 to take a video and sends the real-time monitoring image to the correspondent node 20.
Specifically, the image pickup apparatus 10 maintains data interaction with the correspondent node 20 using the first communication module 11 in the standby state. When the user views the real-time monitoring image, the correspondent node 20 sends a first instruction to the first processor 13 through the first communication module 11. After receiving the first instruction through the first communication module 11, the first processor 13 starts the camera assembly 14, and at the same time, the first processor 13 switches the first communication module 11 communicating with the correspondent node 20 to the second communication module 12. The camera assembly 14 starts to capture images, the first processor 13 processes the captured images, and transmits the processed images to the correspondent node 20 through the second communication module 12, so that the user can view the real-time monitoring images. When the user finishes viewing the image, the correspondent node 20 sends a second instruction to the first processor 13 through the second communication module 12. After the first processor 13 receives the second instruction through the second communication module 12, the first processor 13 switches the communication module to the first communication module 11, and maintains data interaction with the correspondent node 20.
In another scenario, the sensor 15 is used to detect whether a living body is present in the environment, for example, the sensor 15 in this embodiment is an infrared sensor, which can detect the heat of the object in the environment to determine whether the living body is present in the environment. When the sensor 15 detects the presence of a biological object in the environment, a signal is sent to the first processor 13. After receiving the signal, the first processor 13 starts the camera assembly 14, switches the communication module to the second communication module 12, and sends a monitoring picture to the correspondent node 20 through the second communication module 12, while keeping the first communication module 11 in a non-working state. When the sensor 15 detects the disappearance of the organisms present in the environment, it sends a signal to the first processor 13. After the first processor 13 receives the signal, the camera assembly 14 is turned off, the communication module is switched to the first communication module 11, data interaction with the correspondent node 20 is maintained through the first communication module 11, and meanwhile the second communication module 12 is kept in a non-working state.
It is understood that in one embodiment, when the sensor 15 detects the presence of a living organism in the environment, the first processor 13 only turns on the camera assembly 14, and does not switch the communication module; in another embodiment, the sensor 15 turns on the camera assembly 14 when it detects the presence of a living being in the environment, and simultaneously switches the communication module to the second communication module 12.
It can be understood that, in an embodiment, the first processor 13 only turns on the camera assembly 14 when receiving a first instruction of invoking the monitoring picture sent by the correspondent node 20, and does not perform switching of the communication modules; in another embodiment, when the first processor 13 receives a first instruction of invoking the monitoring picture sent by the correspondent node 20, the first processor 13 turns on the camera assembly 14 and simultaneously switches the communication module to the second communication module 12.
In addition, the first processor 13 is further configured to send a warning signal to the correspondent node 20 through the second communication module 12 when sending the monitoring screen to the correspondent node 20, so that the user can view the monitoring screen in time.

Referring to fig. 9, fig. 9 is a schematic diagram of a specific structure of the embodiment of the image capturing apparatus provided in fig. 6.
The camera system includes a camera 10 and a correspondent node 20.
The first communication module 11 is a Sub-1G module 11a, the second communication module 12 is a WiFi module 12a, and the power consumption of the Sub-1G module 11a is less than that of the WiFi module 12 a. The first processor 13 is a Microprocessor (MCU)13a, the second processor 141 is a Central Processing Unit (CPU)141a, and the sensor 15 is an infrared sensor 15 a. The battery assembly 16 includes a battery 161 and a power manager 162. The correspondent node 20 is a base station host 20 a.
The Microprocessor (MCU)13a is used for logic control, specifically for receiving commands sent by the base station host 20 and feedback signals sent by the infrared sensor 15a, and switching communication modules. The Central Processing Unit (CPU)141a is configured to process the image captured by the camera 142, and send the processed image to the base station host 20a through the Sub-1G module 11a or the WiFi module 12 a.
The camera device 10 and the communication opposite terminal 20 perform data interaction through the WiFi module 12a and the Sub-1G module 11 a. Wherein, the power consumption of the Sub-1G module 11a is less than that of the WiFi module 12 a.
Further, the communication peer 20 may store the WiFi physical address and the static IP address of the camera device 10 for a long time, and does not need to reconfigure the IP after the WiFi module 12a of the camera device 10 is turned on, so as to reduce the time for reconnection, and similarly, the camera device 10 may take the service set identifier, the WiFi connection password, and the channel information that the base station host 20a and the WiFi module 12a are connected to through the Sub-1G module 11a, and may directly connect when the WiFi module 12a of the camera device 10 is turned on.
In the standby state of the camera device 10, the WiFi module 12a is in a power-off state, and the camera device 10 maintains data interaction with the base station host 20a through the Sub-1G module 11 a. When the user views the real-time image through the base station host 20a, the base station host 20a sends a first instruction to the Microprocessor (MCU)13a through the Sub-1G module 11 a. The Microprocessor (MCU)13a receives the first instruction, then sends a third instruction to activate the Central Processing Unit (CPU)141a, and switches to the WiFi module 12a to perform data interaction with the base station host 20 a. The Central Processing Unit (CPU)141a turns on the camera 142 and establishes a data connection with the WiFi module 12 a. Meanwhile, the Microprocessor (MCU)13a sends an instruction to the power manager 162, the power manager 162 distributes power to the WiFi module 12a, the Microprocessor (MCU)13a establishes WiFi connection with the base station host 20a, and then sends an instruction to the power manager 162 to power off the Sub-1G module 11 a. The camera 142 starts to capture images, the Central Processing Unit (CPU)141a processes the captured images and transmits the images to the base station host 20a through the WiFi module 12a, and the user views the monitored images in real time.
When the user finishes watching the image, the base station host 20a transmits a second command to the Microprocessor (MCU)13a via the WiFi module 12 a. After receiving the instruction, the Microprocessor (MCU)13a issues a fourth instruction to turn off the camera assembly 14. The camera 142 stops taking the image, and the Central Processing Unit (CPU)141a disconnects from the WiFi module 12 a. Meanwhile, the Microprocessor (MCU)13a switches to the Sub-1G module 11a to connect with the base station host 20 a. Before that, the Microprocessor (MCU)13a issues an instruction to the power manager 162, and the power manager 162 distributes power to the Sub-1G module 11a, and then powers off the WiFi module 12 a. The imaging apparatus 10 is kept connected to the base station host 20a by the Sub-1G module 11a and stands by.
In another case, the infrared sensor 15a detects the presence of a biological object in the monitored environment and sends a signal to the Microprocessor (MCU)13 a. The Microprocessor (MCU)13a sends a third command to the Central Processing Unit (CPU)141a, and switches to the WiFi module 12a to perform data interaction with the base station host 20a, and sends a command to the power manager 162, and the power manager 162 distributes power to the WiFi module 12 a. At the same time, the Microprocessor (MCU)13a sends a warning signal to the base station host 20a through the Sub-1G module 11 a. After receiving the second instruction, the Central Processing Unit (CPU)141a turns on the camera 142, and establishes a data connection with the WiFi module 12 a. After the Micro Controller Unit (MCU)13a establishes the WiFi module 12a connection with the base station host 20a, the power manager 162 powers off the Sub-1G module 11a, and the Micro Controller Unit (MCU)13a continues to send a warning signal to the base station host 20a through the WiFi module 12 a. The camera 142 captures images, and the Microprocessor (MCU)13a processes the captured images and transmits the images to the base station host 20a through the WiFi module 12a, so that the user can confirm the warning information and view the monitored images in real time.
After the user confirms that everything is normal, the camera device 10 returns to the state of maintaining data interaction with the base station host 20a through the Sub-1G module 11 a.
As described above, the camera device 10 maintains data interaction with the base station host 20a through the Sub-1G module 11a at regular time, and performs data interaction with the base station host 20a by using the WiFi module 12a when the user views the real-time monitoring image. In this way, the remote image watching function can be guaranteed, the standby power consumption of the camera device 10 is effectively reduced, the endurance time of the battery is prolonged, the WiFi can be quickly connected with the base station host 20a after being started, the time is within 1 second, the user does not need to wait for too long time, and the experience can be guaranteed.

Through the mode, the communication modules with different power consumptions can be selected according to the communication requirements in the data interaction process, and the communication requirements for performing data interaction by the camera device for most of time are low.
