Description
Technical Field
The present disclosure relates to a camera.
And more particularly, to a low power consumption camera, and a method for controlling the camera.
Background
Currently, a commercially available low-power consumption camera mainly adopts a Passive infra-red-detected (PIR) detector as a trigger mode. The camera is not powered on normally, and the camera is triggered to be powered on when the PIR detects that a person or an animal approaches, so that the purpose of reducing power consumption is achieved.
However, in a commercially available low-power camera, the camera starts shooting only when the PIR detects the approach of a human or an animal, and therefore, it is impossible to shoot a picture when the human or the animal is far away. For example, the entire process of a person or animal passing near the camera cannot be photographed. Furthermore, PIRs are only suitable for detecting the approach of a person or animal, so a camera can only be triggered by the approach of a person or animal, but not by the approach of other objects (e.g. vehicles etc.).
Accordingly, there is a need for an improved low power camera that overcomes the above-mentioned problems of the prior art.

Fig. 1 shows a schematic block diagram of a low power consumption video camera 100 according to at least one embodiment of the present disclosure. The camera 100 may include a sensor 110 and a control chip 120.
The sensor 110 may operate in a low power mode to record low resolution images and may operate in a non-low power mode to record high resolution images. For example, in the low power mode, the sensor 110 may record a VGA image (e.g., an image with a resolution of 640 x 480), while in the non-low power mode, the sensor 110 may record, for example, a 1080P image (an image with a resolution of 1920 x 1080) or a 4M image (an image with a resolution of 2560 x 1440). In the low power mode, the power consumption of the sensor 110 is significantly lower than in the non-low power mode described above. Sensor 110 is normally operated in a low power mode to reduce power consumption and only operated in a non-low power mode when triggered.
The control chip 120 may trigger the sensor 110 to operate in a non-low power mode (similar to the normal operating mode mentioned herein) to record high resolution images. The control chip 120 includes a low power consumption region 130 and a non-low power consumption region 140. Low power consumption region 130 consumes less power while non-low power consumption region 140 consumes significantly more power than low power consumption region 130. That is, the low power consumption region 130 generally operates in a low power consumption mode, and the non-low power consumption region 140 generally operates in a normal operation mode. For example, in the low power consumption mode, the power consumption may be below 10mW, preferably below 5 mW. In the normal operation mode, the power consumption may be 300-1500mW, mainly depending on the resolution and frame rate of the image, etc. During operation of the camera 100, the low power consumption region 130 is Always powered On (Always On, AO mode), while the non-low power consumption region 140 is powered On only when triggered.
In a preferred embodiment, the control chip 120 may be implemented by a single chip, and the low power consumption region 130 and the non-low power consumption region 140 may be spaced apart on the control chip 120. In a further preferred embodiment, low power consumption region 130 may include a microcontroller, non-low power consumption region 140 may include a processor, the microcontroller and the processor may be coupled by inter-core communication, and low power consumption region 130 and non-low power consumption region 140 may share a memory. In other embodiments, the control chip 120 may be implemented by two or more chips, and the low power consumption region 130 and the non-low power consumption region 140 may be respectively disposed on different chips.
The low power consumption region 130 of the control chip 120 may include a detection module 131, a compression module 132, and a storage module 133.
When the sensor 110 operates in the low power consumption mode, the detection module 131 may detect a low resolution image captured by the sensor 110 to determine whether a recording trigger event occurs, and when the recording trigger event occurs, trigger the sensor 110 to operate in the non-low power consumption mode and trigger the non-low power consumption area 140 of the control chip 120 to be powered on.
In a preferred embodiment, the video recording trigger events detected by the detection module 131 may include the proximity of people, animals, and other objects of interest. In a preferred embodiment, the detection module 131 may detect a low resolution image captured by the sensor 110 through an image recognition algorithm to determine whether a recording trigger event occurs. Unlike the prior art that utilizes PIR to trigger sensor power-up, in the present invention, the detection module 131 is able to recognize the proximity of objects other than people and animals (e.g., vehicles). Furthermore, the accuracy of identifying the proximity of people, animals and other objects of interest by AI image recognition algorithms is higher than that of PIRs employed in the prior art. Therefore, the invention realizes more timely and more accurate triggering.
The compression module 132 compresses the low resolution image captured by the sensor 110 when the sensor 110 operates in the low power mode. The compression module 132 may compress the low resolution image captured by the sensor 110 using any suitable compression algorithm (lossy compression or lossless compression) known to those skilled in the art. The compression algorithm of the compression module 132 may be appropriately selected to reduce power consumption of compression and simultaneously save a storage space for storing the compressed image.
The storage module 133 stores the low resolution image compressed by the compression module 132 when the sensor 110 operates in the low power consumption mode. In a preferred embodiment, the storage module 133 can store the low-resolution images captured by the sensor 110 in a circular queue manner. For example, several tens of frames of low-resolution images may be stored in the storage module 133 in a circular queue manner.
The non-low power consumption region 140 of the control chip 120 may include a decompression module 141, a super-resolution module 142, and a video packing module 143. The non-low power consumption region 140 may be powered up in response to the triggering of the detection module 131.
The decompression module 141 may decompress the low resolution image stored in the storage module 133 when the non-low power consumption region 140 is powered on.
The super-resolution module 142 may process the low-resolution image decompressed by the decompression module 141 to increase its resolution. The super-resolution module 142 may process the low-resolution image to become a high-resolution image, thereby improving the quality of the image. In a preferred embodiment, the resolution of the low resolution image may be increased to be the same as or similar to the resolution of the high resolution image captured by the sensor 110 in the non-low power mode. In a preferred embodiment, the super-resolution module 142 may utilize an artificial intelligence algorithm (e.g., AI hyper-resolution algorithm) to process the low resolution images decompressed by the decompression module 141 to increase their resolution.
The video packing module 143 may compress the low resolution images processed by the super resolution module 142 (in a preferred embodiment, the resolution of which has been increased to be the same as or similar to the resolution of the high resolution images) and the high resolution images captured by the sensor 110 in the non-low power mode, and stitch the images in a time sequence, thereby obtaining a video package.
Thus, video packaging module 143 generates video packets that include both high resolution images captured by sensor 110 in a non-low power mode after detecting a video trigger event and low resolution images captured by sensor 110 in a low power mode before detecting a video trigger event (which images have been processed to increase resolution). Thus, the video camera 100 can capture the entire process of the occurrence of the recording trigger event and display it to the user without losing the picture immediately after the start of the recording trigger event due to the delay from the occurrence of the recording trigger event to its detection. In addition, the camera 100 is also capable of displaying a picture for a period of time before a video recording trigger event occurs for reference. For example, in the case of a person passing by, the disclosed camera 100 can capture the entire process of the person passing by and display it to the user. In contrast, prior art cameras can only capture pictures after the person has moved sufficiently close to the PIR.
In a preferred embodiment, the camera 100 may also include a passive infrared detector (PIR) 150. The passive infrared detector 150 is used to detect the approach of a human or animal to determine whether a video recording triggering event occurs, and when the video recording triggering event occurs, the triggering sensor 110 operates in a non-low power mode and triggers the non-low power area 130 of the control chip 120 to be powered on.
The detection of the video trigger event by the passive infrared detector 150 may be supplemented by the detection of the video trigger event by the detection module 131 of the control chip 120. In particular, in low light scenes (e.g., at night), the passive infrared detector 150 may be used primarily to detect video trigger events.
In a preferred embodiment, the camera 100 may further include a communication module 160 capable of communicating with the cloud platform 180 and the terminal device 190. The communication module 160 is configured to send the video package generated by the video packaging module 143 to the cloud platform 180. In a preferred embodiment, the communication module 160 may also detect an instruction from a user as a video recording trigger event. When the communication module 160 receives a control instruction indicating a video recording trigger event from the terminal device 190, it may be detected as a video recording trigger event, and trigger the sensor 110 to operate in the non-low power mode and trigger the non-low power region 130 of the control chip 120 to power up. In this way, the video camera 100 can perform shooting in response to an instruction of the user.
Fig. 2 illustrates a flow chart of a method 200 for controlling the camera 100 shown in fig. 1 in accordance with at least one embodiment of the present disclosure. The method 200 begins at block 201 and proceeds to block 202.
At block 202, the sensor 110 of the camera 100 operates in a low power mode to record a low resolution image.
At block 204, the low resolution image captured by the sensor 110 is compressed in a low power mode. As shown in fig. 1, the compression module 132 of the control chip 120 may be utilized to compress the low-resolution image recorded by the sensor 110.
At block 206, the compressed low resolution image is stored in a low power consumption mode. As shown in fig. 1, the low resolution image compressed by the compression module 132 may be stored using the storage module 133 of the control chip 120. In a preferred embodiment, the compressed low resolution images may be stored in a circular queue.
At block 208, a low resolution image captured by the sensor 110 is detected in a low power mode to determine whether a record trigger event has occurred. As shown in fig. 1, the detection module 131 of the control chip 120 may be utilized to detect a low-resolution image captured by the sensor 110 to determine whether a recording triggering event occurs.
In a preferred embodiment, the video recording trigger event may include the proximity of a person, animal or other object of interest (e.g., a vehicle). In a preferred embodiment, the low resolution image captured by the sensor 110 may be detected by an image recognition algorithm to determine whether a record trigger event has occurred.
Among them, the detection module 131, the compression module 132, and the storage module 133 may be disposed in the low power consumption region 130 of the control chip 120, and the low power consumption region 130 is always powered on during the operation of the video camera 100.
Optionally, as shown in fig. 2, the method 200 may further include at least one of steps 291 and 292.
In block 291, the passive infrared detector 150 of the camera 100 may detect the proximity of a human or animal to determine whether a video recording trigger event has occurred. In particular, the passive infrared detector 150 may be used primarily to detect video trigger events in low light scenes.
In block 292, an instruction may be received from the user indicating a record trigger event. As shown in fig. 1, the camera 100 may include a communication module 160 in communication with the terminal device 190, and the communication module 160 may receive an instruction indicating a video recording trigger event from a user via the terminal device 190.
At block 210, a determination is made as to whether a record trigger event has occurred. Whether a video recording trigger event has occurred may be determined based on the determination result of at least one of steps 208, 291, and 292.
In the preferred embodiment, if a record trigger event is determined to occur in any of steps 208, 291, and 292, then a record trigger event is determined to occur in step 210. For example, if the detection module 131 does not detect the proximity of a person, animal or other object of interest in step 208 and the passive infrared detector 150 does detect the proximity of a person, animal or other object of interest in step 291, but receives an instruction from the user indicating a video recording trigger event in step 292, then the video recording trigger event is determined to occur in step 210. In other embodiments, other logic may be employed to determine whether a record trigger event occurs based on the determination of at least one of steps 208, 291, and 292.
If a record trigger event has not occurred (i.e., "no" determination at block 210), then returning to block 202, the sensor 110 continues to operate in the low power mode to record the low resolution image.
If a record trigger event occurs (i.e., "yes" determination at block 210), the operations of blocks 212 through 218 are performed. The operations of blocks 212 through 218 may be performed in a normal operating mode in which power consumption is significantly higher than in the low power mode described above.
At block 212, the trigger sensor 110 operates in a non-low power mode to record high resolution images. In this non-low power mode, the power consumption of sensor 110 is significantly higher than in the low power mode described above. As shown in fig. 1, the detection module 131 of the control chip 120 may be utilized to trigger the sensor 110 to operate in a non-low power consumption mode.
At block 214, the stored compressed low resolution image is decompressed. As shown in fig. 1, the low resolution image stored by the storage module 133 compressed by the compression module 132 may be decompressed by the decompression module 141 of the control chip 120.
At block 216, the decompressed low resolution image is processed to increase its resolution. As shown in fig. 1, the low resolution image decompressed by the decompression module 141 may be processed by the super resolution module 142 of the control chip 120 to increase its resolution. In a preferred embodiment, the resolution of the low resolution image can be increased to be the same as or similar to the resolution of the high resolution image captured by the sensor 110 in the non-low power mode.
At block 218, the processed increased resolution low resolution image and the high resolution image captured by the sensor 110 in the non-low power mode are compressed and temporally stitched to obtain a video package. As shown in fig. 1, the video packing module 143 of the control chip 120 may be utilized to compress and stitch the images, so as to obtain a video package.
Among them, the decompression module 141, the super-resolution module 142, and the video packing module 143 may be disposed in the non-low power consumption region 140 of the control chip 120. The non-low power consumption region 140 may be powered up in response to the triggering of the detection module 131. In a preferred embodiment, non-low power consumption region 140 may also be powered up in response to the triggering of passive infrared detector 150 and/or communication module 160.
At block 220, the video package may be sent to the cloud platform. As shown in fig. 1, the video package may be transmitted to the cloud platform 180 through the communication module 160.
At block 222, the method 200 ends.
