[0014] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0015] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0016] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0017] Please see Figure 1 , Figure 1A flowchart of a control method provided in an embodiment of this application. The control method is applied to a camera, which is mounted on the side wall of a device for monitoring organisms within the device. The method includes: S1: Control the camera to capture images of organisms inside the device in real time and generate captured images; S2: When it is determined from the captured image that the organism in the device has a first type of behavior, the image recording the first type of behavior in the captured image is cropped as the target image; S3: Save the target image.

[0018] The camera in this application can not only capture images of organisms inside the device in real time and generate images, but also filter target images based on preset conditions and save the filtered target images. This method can automatically filter target images without requiring users to search for the required images themselves. Compared with existing technologies, it saves users time and effort, and also makes it easier for users to view the images they need, thus improving the user experience.

[0019] In some embodiments, the captured images include photographs and videos.

[0020] In some embodiments, in addition to the target image, other non-target images can also be saved. The target image is saved in one folder, and the non-target images are saved in another folder, so that users can view the images as needed.

[0021] In some embodiments, only the target image is saved and other non-target images are deleted. This can prevent unnecessary images from occupying too much of the camera's memory, and thus minimize the chance of the camera running slowly and / or experiencing lag.

[0022] Specifically, the camera can be mounted on the side wall of the device. In some embodiments, the camera is attached to the side wall of the device using Velcro. The Velcro includes a first Velcro and a second Velcro. One side of the first Velcro is attached to the side wall of the device, and the hook side (or loop side) of the first Velcro is attached to the loop side (or hook side) of the second Velcro. The other side of the second Velcro is attached to the lens of the camera. The Velcro has holes to expose the lens of the camera so as to capture images from within the device.

[0023] In other embodiments, the camera is mounted on the side wall of the device via a snap-fit ​​structure, with one side of the snap-fit ​​structure being attached to or mounted on the side wall of the device, and the other side of the snap-fit ​​structure being fixedly connected to the camera.

[0024] In other embodiments, the camera is magnetically attached to the side wall of the device. The housing around the lens of the camera is a metal housing. A magnetic element is attached or installed on the side wall of the device, and the magnetic element magnetically attracts the metal housing to attach the camera to the side wall of the device. Alternatively, a first magnetic element is attached or installed on the side wall of the device, and a second magnetic element is attached around the lens of the camera. The camera is attached to the side wall of the device by the magnetic attraction of the first and second magnetic elements.

[0025] It is understood that the installation of the camera on the side wall of the device is not limited to the above installation scheme, and can be set according to actual needs.

[0026] In some embodiments, the device can be a transparent container such as an aquarium, fish tank, or glass tank. In this case, the camera can be installed on the outer or inner wall of the device according to the actual situation, and images including organisms can be captured in real time. In other embodiments, when the device is an opaque container such as a foam box or plastic box, the camera needs to be installed on the side wall of the device with the lens facing inward.

[0027] Specifically, in some embodiments, when aquatic organisms are raised inside the device, the camera is installed on the outer wall of the device with its lens facing inwards to monitor the aquatic organisms inside. Alternatively, the camera may be waterproof, allowing it to remain submerged in the water within the device, in which case it can be installed on the inner wall of the device. In other embodiments, when non-aquatic organisms such as reptiles and birds are raised inside the device, the camera may be selectively installed on either the outer or inner wall of the device.

[0028] In some embodiments, the camera can also be used in zoos, in which case the device can be a fence, support structure, or other equipment within the zoo that can be equipped with a camera to monitor and photograph the organisms within the enclosure formed by the fence, support structure, etc., in real time.

[0029] In some embodiments, the first type of behavior includes one or more of the following: fish jumping, fish swimming, birds flying, birds nest building, reptile crawling, and biological reproductive behavior.

[0030] Therefore, the camera in this application can filter out target images including the first type of behavior to record the wonderful moments of the organism, and save the filtered target images. This method can automatically filter out target images with wonderful moments without requiring the user to search for them. Compared with the prior art, it saves the user's time and effort, and also makes it easier for the user to view the images they need, thus improving the user experience.

[0031] Specifically, in some embodiments, the user sets the first type of behavior, and when the user does not set the first type of behavior, the target image is filtered based on the first type of behavior set in the factory settings.

[0032] It is understood that the first type of behavior is not limited to the behaviors mentioned above, but may also include behaviors such as playing and eating. The first type of behavior can be set according to the user's needs, so that the camera can filter and save the images that the user wants.

[0033] In some embodiments, the camera further includes a communication unit, through which the camera communicates with a terminal device; the method further includes: The target image is sent to the terminal device through the communication unit.

[0034] Therefore, users can view the target image on the terminal device themselves without needing to view the target image through the camera, and when users are away, they can view the target image on the terminal device to know the activity status of the organism in a timely manner.

[0035] In some embodiments, the camera can transmit folders containing the target image and non-target images to the terminal device respectively, allowing the user to directly view all images on the terminal device and selectively view either the target image or the non-target image.

[0036] In some embodiments, the user can set the first type of behavior on the camera or on the terminal device.

[0037] Please see Figure 2 , Figure 2 A flowchart illustrating the adjustment of sharpness according to an embodiment of this application. The method further includes: S4: Determine the target organism based on the images obtained from the real-time monitoring of the camera; S5: When the clarity of the target organism image in the obtained image is lower than a preset value, focus is applied to the target organism.

[0038] Therefore, the clarity of the target organism image can be adjusted by focusing, so that the user can see the target organism more clearly and improve the user experience.

[0039] In some embodiments, determining the target organism based on the images obtained from real-time monitoring by the camera includes: The target organism is identified as any creature moving toward the camera in the real-time monitoring footage.

[0040] Therefore, the creature moving towards the camera is identified as the target creature, so as to avoid the creature's clarity in the image not meeting the requirements or being unable to be observed completely as it gradually approaches the camera, allowing the user to see the target creature more completely and clearly.

[0041] In other implementations, the target organism is determined based on the images obtained from the real-time monitoring of the camera. Users can select and determine the target organism from the organisms appearing in the image as needed, or the camera can automatically select the target organism based on other initial screening conditions for the target organism.

[0042] In some embodiments, the method further includes: The target organism is determined based on the images obtained from the real-time monitoring of the camera; When the distance between the target creature and the camera is less than or equal to a preset distance, the focal length of the camera is adjusted to reduce the size of the creature in the image. When the distance between the target creature and the camera is greater than the preset distance, the focal length of the camera is adjusted to magnify the size of the creature in the image.

[0043] Therefore, by adjusting the focal length of the camera, the size of the target creature in the image can be magnified or reduced under corresponding conditions, allowing the camera to specifically monitor the activity of the target creature, enabling the user to see the target creature more completely and clearly, and thus better understand the activity status of the target creature.

[0044] Specifically, to acquire the desired target organism, the camera locates the target organism within the frame based on its needs. When the distance between the target organism and the camera lens is less than or equal to a preset distance—for example, when the target organism moves towards the lens—the camera's focal length can be adjusted adaptively to prevent it from getting too close and obscuring its full appearance. This reduces the size of the target organism in the frame, but the size should not be excessively reduced; the target organism must remain the primary organism in the real-time monitored image. Conversely, when the distance between the target organism and the camera lens exceeds the preset distance (i.e., the target organism moves away from the lens), the camera's focal length can be adjusted to increase its size in the frame, ensuring that the target organism remains the primary organism in the real-time monitored image.

[0045] In some embodiments, the target organism may be an organism that has not yet adapted to the device environment, a sick organism, or other similar organism.

[0046] In some embodiments, the camera may include two lenses with different focal lengths, and the method further includes: When the distance between the target organism and the camera is less than or equal to a preset distance, a lens with a smaller focal length can be controlled to monitor the target organism; when the distance between the target organism and the camera is greater than the preset distance, a lens with a larger focal length can be controlled to monitor the target organism.

[0047] In some embodiments, when one lens is working, the other lens can enter a sleep state (which can be considered as the other lens displaying a black screen).

[0048] In other embodiments, when one lens is working, the other lens is also in a real-time monitoring state, and the images monitored in real time by both lenses can be sent to the mobile terminal, where a picture-in-picture image will be displayed.

[0049] In some embodiments, the method further includes: When it is determined from the real-time monitoring footage obtained by the camera that a creature exhibiting the second type of behavior exists within the device, the camera is controlled to adjust its focus to magnify the size of at least one creature exhibiting the second type of behavior in the image. The second type of behavior includes one or more of stereotyped behavior, twitching, aggressive behavior, loss of balance, and stress behavior.

[0050] Therefore, by controlling the focal length of the camera, the size of the organisms exhibiting the second type of behavior in the image can be magnified, thereby allowing the user to primarily observe the organisms exhibiting the second type of behavior. This enables the user to be aware of the existence of organisms exhibiting the second type of behavior in a timely manner and to understand the specific situation of such organisms. The user can then intervene in the behavior of such organisms and rescue them, thereby improving the survival rate of the organisms within the device.

[0051] In some embodiments, when there are two or more creatures with the second type of behavior in the scene, the creature with the higher priority of the second type of behavior can be monitored, or either one can be selected for monitoring.

[0052] In some embodiments, the camera further includes an alarm, and the method further includes: When at least one creature in the footage obtained from the real-time monitoring of the camera exhibits the second type of behavior, the alarm is controlled to sound an alarm.

[0053] This allows users to be aware of the existence of organisms exhibiting the second type of behavior in a timely manner, and to understand the specific circumstances of such organisms. Users can then intervene in the behavior of these organisms and rescue them, thereby improving the survival rate of the organisms within the device.

[0054] In some embodiments, after the size of the organism is enlarged or reduced by adjusting the focal length of the camera, if the clarity does not meet the requirements, the camera can start focusing to adjust the clarity of the image to meet the requirements.

[0055] In some embodiments, the camera includes a first lens assembly and a second lens assembly, which are disposed opposite to each other. The first lens assembly is used to monitor organisms inside the device, and the second lens assembly is used to monitor organisms outside the device.

[0056] Therefore, in addition to monitoring the creatures inside the device through the first lens assembly, the camera can also monitor the creatures outside the device through the second lens assembly, so that the user knows when other people or animals besides themselves approach the device and what they do to the creatures inside the device.

[0057] For example, the device is a fish tank, the organisms inside the device are fish, and the second lens assembly can monitor whether there are organisms such as cats or birds approaching the device.

[0058] In some embodiments, when a creature of particular interest approaches the device, the camera can issue an alarm via the alarm to scare the creature away.

[0059] Please see Figure 3 , Figure 3 A flowchart illustrating the working state of a light-emitting element according to an embodiment of this application. The camera includes a light-emitting element and a photosensitive element, and the method further includes: S6: Detect the ambient light intensity of the environment in which the camera is located using the photosensitive element; S7: Control the working state of the light-emitting element based on the detected light intensity.

[0060] Therefore, the working state of the light-emitting element is controlled based on the light intensity, so that the organisms and environment inside the device can be clearly seen in different environments.

[0061] In some embodiments, controlling the operating state of the light-emitting element based on the detected light intensity includes: When the detected light intensity is less than the light intensity threshold, the light-emitting element is controlled to emit light.

[0062] Therefore, when the detected light intensity is less than the light intensity threshold, the light-emitting element is controlled to emit light, so that the creatures and environment in the monitoring screen can be seen clearly in the low light intensity environment, thereby improving the user experience.

[0063] In some embodiments, the light-emitting element is an infrared LED. When the light intensity is less than the light intensity threshold, the camera will automatically turn on the light-emitting element, and the camera's image sensor can receive the reflected infrared light, thereby forming a black and white image.

[0064] In some embodiments, the light-emitting element is a warm light lamp. When the light intensity is less than the light intensity threshold, the camera will automatically turn on the light-emitting element to provide supplementary light, so that the camera can form a full-color image.

[0065] In some embodiments, the camera generates thermal images using thermal imaging technology to display the activity of organisms within the device.

[0066] In some embodiments, the camera further includes a display screen, and the method further includes: The acquired image and / or the current parameter information of the camera are sent to the display screen, and the display screen displays corresponding information based on the received image and / or parameter information.

[0067] Thus, users can more intuitively see the acquired images and / or the current parameter information of the camera through the display screen, so that users can understand the activity of the organism and / or the current working status of the camera.

[0068] In some embodiments, the current parameter information of the camera may include parameters such as the camera's focal length, the camera's operating time, and the camera's memory.

[0069] In some embodiments, the camera's display screen may also display the aforementioned target image, or display the folder containing the target image. The camera's display screen is a touch screen, and the user can directly view the target image or enter the folder to view the target image through touch operation.

[0070] In some embodiments, the camera and / or the display screen of the terminal device may also directly display the images obtained by the camera in real time, and the display screen may be touched to zoom in or out on the creatures in the images, and to select the target creatures.
