Description

Technical Field

[0001] This application relates to the field of camera device technology, and in particular to a device and method for recording image information in the event of a power outage. Background Technology

[0002] In recent years, with the advancement of electronic technology, the use of network cameras has become increasingly widespread, for example, in areas such as home care, burglar protection, and security. As the functions of network cameras have become more diverse, they have evolved from wired transmission to wireless transmission, which has also promoted the rapid development of wireless network cameras. Wireless network cameras transmit video signals through a wireless network, differing from ordinary network cameras in the method of video signal transmission. Distinguishing between them based on the wireless transmission method, there are two types of wireless network cameras: one is a wireless Wi-Fi network camera, and the other is a network camera that uses 3G wireless signals from mobile communication operators for signal transmission. Therefore, wireless network cameras require a wireless device for wireless transmission to send the monitored image data to the user's end.

[0003] However, most existing wireless network cameras lack power-saving designs and are constantly in a power-consuming state. This means the wireless device within the camera cannot automatically shut down to save power based on whether the camera is actually operating. This results in unnecessary power loss and reduces the camera's overall efficiency. Summary of the Invention

[0044] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0046] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0047] This application aims to propose a device that can record image information in the absence of power. The solution involves placing a solar cell 1 outside the photosensitive element 2 to provide the electrical energy required for the photosensitive element 2 to take pictures and form images, or coupling the light energy conversion unit and the energy storage unit in the solar cell 1 to the photosensitive element 2 through encapsulation or growth, thereby integrating the light energy conversion unit 21, the energy storage unit 22 and the photosensitive element 2 into a single component, or simultaneously placing the solar cell 1 outside the photosensitive element 2 and coupling the light energy conversion unit 21 and the energy storage unit 22 to the photosensitive element 2 through encapsulation or growth.

[0048] This application provides an apparatus for recording image information in a power-off state. The apparatus includes a photoelectric conversion component, which collects light energy and converts it into electrical energy for storage. The light energy collected by the photoelectric conversion component can be natural sunlight or artificial light energy (such as incandescent lamp or LED lamp). After collecting a certain amount of light energy, the photoelectric conversion component can convert the light energy into electrical energy.

[0049] Photosensitive element 2 is connected to a photoelectric conversion assembly. Photosensitive element 2 is used to receive electrical energy from the photoelectric conversion assembly and to capture images. Photosensitive element 2 is a pattern sensor in the prior art. When the R / G / B photodiode of the pattern sensor receives external light and the pattern sensor receives sufficient electrical energy from the photoelectric conversion assembly to meet the requirements for shooting, shooting begins.

[0050] Specifically, when the voltage of the electrical energy in the photoelectric conversion component reaches a preset electrical energy threshold, the photosensitive element 2 is driven to start capturing images. For example, when the image sensor meets the electrical energy voltage required for capturing images at 20V, the preset threshold is set to 20. When the voltage of the electrical energy after the photoelectric conversion component converts light energy into electrical energy reaches 20V, the photoelectric conversion component drives the photosensitive element 2 to start capturing images.

[0051] It should be noted that the device includes a non-volatile memory 3 connected to the photosensitive element 2. The non-volatile memory 3 is used to receive and record images captured by the photosensitive element 2. When the light source received by the photoelectric conversion component is weak (such as on a cloudy day or at night), the electrical energy converted from light energy is small. Therefore, the electrical energy converted by the photoelectric conversion component is difficult to reach the preset electrical energy threshold. Insufficient voltage when driving the photosensitive element 2 will cause the device to fail to record images and may also cause file corruption. Because the non-volatile memory 3 is a memory that does not lose stored data when the current is turned off, the use of the non-volatile memory 3 ensures that insufficient voltage when driving the photosensitive element 2 will not damage the file. That is, in the case of insufficient voltage, the non-volatile memory 3 will still retain the previously captured image and will not cause file corruption.

[0052] It should also be noted that this includes a data export module 4 connected to the non-volatile memory 3. The data export module 4 is used to output the images recorded in the non-volatile memory 3. The images recorded in the non-volatile memory 3 can be exported via the data export module 4, which can be a USB interface. Furthermore, the data export module 4 can also be connected to a cloud server to transmit the images recorded in the non-volatile memory 3 to a network server.

[0053] At this time, the device does not need to be powered on. It only needs the photoelectric conversion component to be irradiated by a light source to generate electrical energy voltage to drive the photosensitive element 2 to take pictures and record them in the non-volatile memory 3. This eliminates the need for long-term or continuous power supply to record pictures and cause power loss, thereby enabling the device to achieve energy saving.

[0054] Please see Figure 1In a first embodiment of the photoelectric conversion component, the photoelectric conversion component includes a solar cell 1 disposed outside the photosensitive element 2. The solar cell 1 includes: a first light energy conversion unit 11, used to detect the intensity of sunlight and collect solar energy and convert it into electrical energy; the first light energy conversion unit 11 includes a photosensor for detecting the intensity of sunlight; and a first energy storage unit 12, connected to both the first light energy conversion unit 11 and the photosensitive element 2. The first energy storage unit 12 receives and stores the electrical energy from the first light energy conversion unit 11. The electrical energy in the first energy storage unit 12 has a first preset energy threshold for driving the photosensitive element 2 to capture images. When the voltage of the electrical energy stored in the first energy storage unit 12 reaches the first preset energy threshold, the photosensitive element 2 is driven to capture images. It can be understood that the solar cell 1 and the photosensitive element 2 are two separate structures. The photosensitive element 2, as an image sensor, only provides the function of capturing images, while the electrical energy required to drive the photosensitive element 2 to capture images is provided by the solar cell 1 disposed outside the photosensitive element 2.

[0055] The device also includes a controller 5, which is connected to the solar cell 1. The controller 5 is used to set a first preset energy threshold based on the intensity of sunlight detected by the first light energy conversion unit 11. The controller 5 can also set the first preset energy threshold to the voltage required for the photosensitive element 2 to complete two or more full shots. The solar cell 1, composed of the first energy storage unit 12 and the first energy storage unit 12, can be considered a high-capacity battery.

[0056] The photoelectric conversion component provided in this first embodiment is applied in the device. In use, a first preset energy threshold is set as the voltage value required for the photosensitive element 2 to complete one full image capture. The first light energy conversion unit 11 collects solar energy and converts it into electrical energy. The first energy storage unit 12 receives and stores the electrical energy. When the voltage value of the electrical energy from the first light energy conversion unit 11 reaches the first preset energy threshold, the photosensitive element 2 can be driven to start capturing an image. It is worth noting that the speed at which the photosensitive element 2 captures and stores images is faster when sunlight is strong and slower when sunlight is weak. The image can be captured and stored once the voltage of the first energy storage unit 12 meets the first preset energy threshold. This is because the speed at which the voltage value of the first light energy conversion unit 11 reaches the first preset energy threshold increases with increasing sunlight intensity and decreases with decreasing sunlight intensity.

[0057] Please see Figure 2In the second embodiment of the specific structure of the photoelectric conversion component, the photoelectric conversion component includes a second light energy conversion unit 21 and a second energy storage unit 22 coupled in the photosensitive element 2. The second light energy conversion unit 21 and the second energy storage unit 22 are directly connected to the photosensitive element 2. The second light energy conversion unit 21 is used to detect the intensity of sunlight and collect sunlight energy and convert it into electrical energy. The second light energy conversion unit 21 includes a photosensitive sensor for detecting the intensity of sunlight and a capacitor 211 for storing a small amount of electrical energy. After the second light energy conversion unit 21 converts the collected light energy into electrical energy, it temporarily stores the electrical energy in the capacitor 211. The capacitor 211 is electrically connected to the photosensitive element 2 and the second energy storage unit 22. Then, the photosensitive element 2 and the second energy storage unit 22 can be regarded as being on two parallel lines. At this time, the electrical energy in the capacitor 211 will be shunt, so the electrical energy in the capacitor 211 includes the direct electrical energy used to be directly transmitted to the photosensitive element 2 and the shunt electrical energy flowing to the second energy storage unit 22. The direct electrical energy has a second preset electrical energy threshold for driving the photosensitive element 2 to capture images, and the shunt electrical energy stored in the second electrical energy storage unit 22 has a third preset electrical energy threshold for driving the photosensitive element 2 to capture images.

[0058] When the voltage of the direct electrical energy supplied to the photosensitive element 2 in capacitor 211 reaches a second preset energy threshold, the photosensitive element 2 is driven to capture an image. At this time, the function of the second light energy conversion unit 21 is not only to convert sunlight into electrical energy, but also to directly supply a portion of the converted electrical energy stored in capacitor 211 to the photosensitive element 2 so that it can capture an image. When the voltage of the shunt electrical energy stored in the second energy storage unit 22 reaches a third preset energy threshold, the photosensitive element 2 is driven to capture an image.

[0059] The device also includes a controller 5, which is connected to the second light energy conversion unit 21 and the second energy storage unit 22. The controller 5 is used to set a second preset energy threshold and a third preset energy threshold according to the intensity of sunlight detected by the second light energy conversion unit 21. The photosensor in the second light energy conversion unit 21, which is used to detect the intensity of sunlight, is electrically or communicatively connected to the controller 5.

[0060] When the voltage of the direct electrical energy supplied to the photosensitive element 2 does not reach the second preset electrical energy threshold, the direct electrical energy cannot drive the photosensitive element 2 to complete the image capture. Simultaneously, the second energy storage unit 22 receives the shunt electrical energy supplied from the capacitor 211 and stores it within itself. It should be noted that the second light energy conversion unit 21 also has a time threshold. If the direct electrical energy in the capacitor 211 of the second light energy conversion unit 21 fails to reach the second preset electrical energy threshold within the specified time, the controller 5 sets a third preset electrical energy threshold. This continues until the voltage of the shunt electrical energy reaches the third preset electrical energy threshold, at which point the second energy storage unit 22 also supplies the stored shunt electrical energy to the photosensitive element 2, allowing the second energy storage unit 22 to drive the photosensitive element 2 to capture an image.

[0061] The second preset energy threshold can also be set by the controller to the voltage value required for the photosensitive element 2 to complete one full shot. It should be noted that, since another part of the shunt energy needs to be delivered to the second energy storage unit 22 in the capacitor 211, the time required for the voltage of the direct energy delivered to the photosensitive element 2 in the capacitor 211 to reach the second preset energy threshold is longer than the time required for the voltage value of the energy in the first energy storage unit 12 to reach the first preset energy threshold in Embodiment 1.

[0062] Furthermore, the controller 5 can set a period based on the intensity of sunlight detected by the second light energy conversion unit 21. The second light energy conversion unit 21 delivers shunt power to the second energy storage unit 22 according to the set period. The set period can be 5s or 10s. Then, the second light energy conversion unit 21 will periodically deliver shunt power to the second energy storage unit 22 through the capacitor 211 every 5s or 10s. It can be understood that the capacitor 211 in the second light energy conversion unit 21 does not continuously deliver shunt power to the second energy storage unit 22. The capacitor 211 delivers shunt power to the second energy storage unit 22 at intervals of the set period, so that the direct power can quickly reach the first preset power threshold to drive the photosensitive element 2 to take pictures.

[0063] The photoelectric conversion component provided in this second embodiment is applied in the device. When the sunlight is strong during the day, the controller 5 sets the second preset power threshold to the voltage required for the photosensitive element 2 to complete one full shot. At this time, the third preset power threshold is set to be much larger than the second preset power threshold. The purpose of this setting is to make it easy for the direct power in the capacitor 211 in the second light energy conversion unit 21 to reach the second preset power threshold when the sunlight is strong, so that only the capacitor 211 in the second light energy conversion unit 21 supplies power to the photosensitive element 2. Although the second power storage unit 22 also receives and stores the shunt power from the capacitor 211, the shunt power stored in the second power storage unit 22 is not easy to reach the third preset power threshold because the value of the third preset power threshold is relatively high. The advantage of this is that the shunt power stored in the second power storage unit 22 will not be wasted when the sunlight is strong. So that when there is weak or no sunlight, the controller 5 can reduce the third preset power threshold so that the shunt power stored in the second power storage unit 22 can also power the photosensitive element 2.

[0064] For example, assuming that the power voltage required for the photosensitive element 2 to complete one full shot is 20V, when the sunlight is weak during the day, the photosensor in the second light energy conversion unit 21 detects the weakening of the sunlight and sends a control signal to the controller 5. The controller 5 sets the second preset power threshold to be lower than the power voltage required for the photosensitive element 2 to complete one full shot, specifically 10V. The controller 5 also sets the third preset power threshold to be lower than the power voltage required for the photosensitive element 2 to complete one full shot, specifically 10V. At this time, the second preset power threshold and the third preset power threshold are equal. Therefore, the power required for the photosensitive element 2 to take a shot is provided by the direct power supplied to the photosensitive element 2 by the capacitor 211 and the shunt power in the second power storage unit 22.

[0065] For example, assuming that the power voltage required for the photosensitive element 2 to complete one full shot is 20V, when there is no sunlight at night, the photosensitive element in the second light energy conversion unit 21 cannot detect sunlight. The photosensitive element will send a control signal to the controller 5. Since the second energy storage unit 22 stores a certain amount of shunt power from the capacitor 211 during the day, the power required for the photosensitive element 2 to take a picture at this time only needs to be provided by the shunt power of the second energy storage unit 22. The controller 5 sets the third preset power threshold to the value of the power voltage required for the photosensitive element 2 to complete one full shot, specifically 20V. At this time, only the second energy storage unit 22 supplies power to the photosensitive element 2 to complete the shot.

[0066] For example, assuming that the power voltage required for the photosensitive element 2 to complete one full shot is 20V, when the sunlight is strong during the day, when the second light energy conversion unit 21 detects the increased sunlight, the controller 5 sets the second preset power threshold to the value of the power voltage required for the photosensitive element 2 to complete one full shot, specifically 20V, and the controller 5 sets the third preset power threshold to be much larger than the second preset power threshold, such as 200V.

[0067] Please see Figure 3 In the third embodiment of the specific structure of the photoelectric conversion component, compared with the first and second embodiments, the third embodiment is equivalent to combining the first and second embodiments to ensure that the photoelectric conversion component still stores enough electrical energy to supply the photosensitive element for shooting in the absence of sunlight during a short period of time (e.g., one or two days).

[0068] The photoelectric conversion assembly includes a solar cell 1 disposed outside the photosensitive element 2. The solar cell 1 includes: a first light energy conversion unit 11, used to detect the intensity of sunlight and collect solar energy and convert it into electrical energy; the first light energy conversion unit 11 includes a photosensor for detecting the intensity of sunlight; and a first energy storage unit 12, connected to both the first light energy conversion unit 11 and the photosensitive element 2. The first energy storage unit 12 receives and stores the electrical energy of the first light energy conversion unit 11. The electrical energy in the first energy storage unit 12 has a first preset energy threshold for driving the photosensitive element 2 to capture images. When the voltage of the electrical energy stored in the first energy storage unit 12 reaches the first preset energy threshold, it drives the photosensitive element 2 to capture images.

[0069] The photoelectric conversion component includes a second light energy conversion unit 21 and a second energy storage unit 22 coupled to the photosensitive element 2. The second light energy conversion unit 21 and the second energy storage unit 22 are directly connected to the photosensitive element 2. The second light energy conversion unit 21 is used to detect the intensity of sunlight and collect sunlight energy and convert it into electrical energy. The second light energy conversion unit 21 includes a photosensitive sensor for detecting the intensity of sunlight and a capacitor 211 for storing a small amount of electrical energy. After the second light energy conversion unit 21 converts the collected light energy into electrical energy, it temporarily stores the electrical energy in the capacitor 211. The capacitor 211 is electrically connected to the photosensitive element 2 and the second energy storage unit 22. The photosensitive element 2 and the second energy storage unit 22 can be regarded as being on two parallel lines. At this time, the electrical energy in the capacitor 211 will be shunted. Thus, the electrical energy in the capacitor 211 includes the direct electrical energy used to be directly transmitted to the photosensitive element 2 and the shunted electrical energy flowing to the second energy storage unit 22. The direct electrical energy has a second preset electrical energy threshold for driving the photosensitive element 2 to capture images, and the shunt electrical energy stored in the second electrical energy storage unit 22 has a third preset electrical energy threshold for driving the photosensitive element 2 to capture images. When the voltage of the direct electrical energy in capacitor 211 used to directly supply the photosensitive element 2 reaches the second preset electrical energy threshold, the photosensitive element 2 is driven to capture images. At this time, the function of the second light energy conversion unit 21 is not only to convert sunlight into electrical energy, but also to directly supply a portion of the converted electrical energy stored in capacitor 211 to the photosensitive element 2 so that the photosensitive element 2 can capture images. When the voltage of the shunt electrical energy stored in the second electrical energy storage unit 22 reaches the third preset electrical energy threshold, the photosensitive element 2 is driven to capture images.

[0070] The device also includes a controller 5, which is connected to the solar cell 1, the second solar energy conversion unit 21, and the second energy storage unit 22. The controller 5 is used to set a first preset energy threshold based on the sunlight intensity detected by the first solar energy conversion unit 11, and to set a second preset energy threshold and a third preset energy threshold based on the sunlight intensity detected by the second solar energy conversion unit 21. The photosensor in the second solar energy conversion unit 21, used to detect sunlight intensity, is electrically or communicatively connected to the controller 5.

[0071] It should also be noted that the second energy storage unit 22 has a time threshold. If the direct energy in the capacitor 211 of the second light energy conversion unit 21 does not reach the second preset energy threshold within the time limit, the controller 5 is activated to set the first preset energy threshold, thereby enabling the first energy storage unit 12 in the solar cell 1 to supply energy to the photosensitive element 2.

[0072] The photoelectric conversion component provided in this third embodiment is applied in the device. When there is no sunlight for a short period (e.g., one or two days), it is obvious that the second light energy conversion unit 21 cannot detect the sun during this period. At this time, the electrical energy in the capacitor 211 is zero, and simultaneously, when the electrical energy in the second energy storage unit 22 is depleted, the voltage in the second energy storage unit 22 does not reach the third preset energy threshold within a certain time threshold. At this time, the first preset energy threshold, which was previously much larger than the second and third preset energy thresholds, is reset by the controller 5 to the value of the energy voltage required for the photosensitive element 2 to complete one full shot. At this time, the solar cell 1 is equivalent to a large-capacity battery, thus the solar cell 1 supplies power to the photosensitive element 2 to enable it to take pictures.

[0073] For example, assuming that the power voltage required for the photosensitive element 2 to complete one full shot is 20V, when there is no sunlight for a short period of time (e.g., one or two days), when the power in the second power storage unit 22 is used up, and when the first light energy conversion unit 11 and the second light energy conversion unit 21 cannot detect sunlight for a long time, the photosensors in the first light energy conversion unit 11 and the second light energy conversion unit 21 send a signal to the controller 5. Then the controller 5 resets the first preset power threshold from the previous value which was much greater than the second preset power threshold and the third preset power threshold to the value of the power voltage required for the photosensitive element 2 to complete one full shot, specifically 20V.

[0074] Please see Figure 4 In the fourth embodiment of the photoelectric conversion component structure, based on the third embodiment, the first light energy conversion unit 11 in the solar cell 1 is removed. The solar cell 1 only includes the first energy storage unit 12, and the other structures are the same as in the third embodiment. At the same time, the capacitor 211 in the second light energy conversion unit 21 is connected to the first energy storage unit 12. At this time, the electrical energy in the capacitor 211 is not only directly supplied to the photosensitive element 2 as electrical energy and shunted to the second energy storage unit 22 as electrical energy, but also a portion of the electrical energy is supplied to the first energy storage unit 12. The controller 5 is connected to the first energy storage unit 12 in the solar cell 1 to set the first preset energy threshold. The function of this embodiment is the same as that of the third embodiment. By supplying a portion of the electrical energy in the capacitor 211 to the first energy storage unit 12 for storage, the solar cell 1 becomes a backup battery for use during periods of no sunlight (e.g., one or two days). The advantage of this arrangement is that, based on the third embodiment, the first light energy conversion unit 11 is omitted, reducing the amount of structural use while achieving the same function as the third embodiment.

[0075] Based on the same concept, referencing Figure 5 This application also proposes a method for recording image information in a power-off state, characterized by comprising the following steps:

[0076] S1. Photovoltaic energy conversion steps: Photovoltaic conversion component 1 collects light energy, converts it into electrical energy, and then stores it;

[0077] S2, Imaging Steps: The photosensitive element 2 receives electrical energy from the photoelectric conversion component and performs imaging;

[0078] S3, Recording Imaging Steps: Non-volatile memory 3 receives and records the image from photosensitive element 2;

[0079] Furthermore, it also includes the following steps: S4, output imaging step: the data export module 4 outputs the image recorded in the non-volatile memory 3.

[0080] Corresponding to the method in the first embodiment of the photoelectric conversion component of the device, specifically, the "photoelectric energy conversion step" includes the first light energy conversion unit 11 collecting solar energy and converting solar energy into electrical energy; the "image capture step" specifically includes the voltage of the electrical energy stored in the first electrical energy storage unit 12 reaching a first preset electrical energy threshold, driving the photosensitive element 2 to capture an image.

[0081] In the second embodiment of the photoelectric conversion component of the device, specifically, the "photoelectric energy conversion step" includes the second light energy conversion unit 21 collecting solar energy and converting it into electrical energy; the "image capture step" specifically includes the second light energy conversion unit 21 directly supplying the voltage of the direct electrical energy to the photosensitive element 2 reaching a second preset electrical energy threshold, thereby driving the photosensitive element 2 to capture an image.

[0082] Specifically, the "image capture step" further includes the following: when the voltage of the direct electrical energy directly supplied by the second light energy conversion unit 21 to the photosensitive element 2 is lower than the second preset electrical energy threshold when the time threshold is exceeded, the controller 5 sets a new third preset electrical energy threshold so that the voltage of the shunt electrical energy of the second electrical energy storage unit 22 reaches the new third preset electrical energy threshold.

[0083] Specifically, the controller 5 reduces the third preset power threshold based on the decrease in sunlight intensity detected by the second light energy conversion unit 21, and reduces the first preset power threshold based on the decrease in sunlight intensity detected by the first light energy conversion unit 11.
