The disclosure relates to the technical field of data processing, in particular to a shooting module protection method, a shooting module protection device, a computer readable medium and an electronic device.
Background
The camera relies on the principle of pinhole imaging and lens imaging, and focuses incident light on a CMOS (Complementary Metal-Oxide-Semiconductor) sensor by using an optical lens, and the CMOS sensor is extremely sensitive to light, thereby forming an image. Laser light, also called laser light, has the characteristics of high energy and precise focusing, and has quite strong directivity, so that the energy emitted by a single point is extremely high, and thus the laser light emits a concentrated light beam, which can heat a sensitive surface and cause damage, so that materials which are naturally sensitive to light, such as a CMOS or a CCD (Charge Coupled Device) or a film, are easily burned under direct laser irradiation, resulting in damage to a camera.
At present, in a related scheme, generally, after a scene is judged to have laser, a dimmer is manually installed in front of a camera lens by a manual judgment mode, so that the intensity of the laser light entering an imaging system is weakened. However, the burn time caused by laser is short, and the manual judgment mode cannot cover all laser scenes, for example, in the process of a user holding a mobile phone for conversation, although a camera is not used, the image sensor of the camera may be damaged in the laser scene, so the accuracy of the manual judgment mode is low, and the manual installation of the dimmer has delay and low efficiency, which easily causes the image sensor in the shooting module to be damaged and reduces the service life of the image sensor.

and the shading component driving module is used for driving the shading component associated with the shooting module through the protection control instruction so as to adjust the light intensity of the light incident to the shooting module according to the shading component.
According to a third aspect of the present disclosure, there is provided a computer readable medium having stored thereon a computer program which, when executed by a processor, performs the method described above.
According to a fourth aspect of the present disclosure, there is provided an electronic apparatus, comprising:
a processor; and
a memory for storing one or more programs which, when executed by the one or more processors, cause the one or more processors to implement the method described above.
The shooting module protection method provided by the embodiment of the disclosure can monitor light irradiating the shooting module, acquire a monitoring image generated when the light is monitored, determine a light type corresponding to the light according to the monitoring image, drive the shading component associated with the shooting module by generating the protection control instruction when the light type is determined to be the target light type, and further adjust the light intensity of the light incident to the shooting module through the shading component. On one hand, the terminal equipment can be used for monitoring light rays by shooting images through the shooting module, and extra hardware is not needed for monitoring the light rays, so that the hardware cost is effectively reduced; on the other hand, the light monitoring is realized by shooting images, compared with the manual judgment mode, the mode is more accurate, the efficiency is more efficient, and based on the low-power-consumption normally open function of the shooting module, the real-time continuous monitoring can be realized, most light monitoring scenes are effectively covered, the comprehensiveness of the light monitoring is improved, and the accuracy of the light monitoring in each scene is further ensured; on the other hand, only when the light is determined to be the target light type which may damage the shooting module, protection is performed, the judgment accuracy of the current scene can be effectively improved, the problems that frequent mistaken identification causes interruption of shooting and reduction of the cruising ability of the terminal device are avoided, and shooting experience is improved.

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
Fig. 1 is a schematic diagram illustrating a system architecture of an exemplary application environment to which a shooting module protection method and apparatus according to an embodiment of the present disclosure may be applied.
As shown in fig. 1, system architecture 100 may include one or more of terminal devices 101, 102, 103, network 104, and server 105. The network 104 serves as a medium for providing communication links between the terminal devices 101, 102, 103 and the server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few. The terminal devices 101, 102, 103 may be various electronic devices having an image processing function, including but not limited to desktop computers, portable computers, smart phones, tablet computers, and the like. It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation. For example, server 105 may be a server cluster comprising a plurality of servers, or the like.
The shooting module protection method provided by the embodiment of the disclosure is generally executed by the terminal devices 101, 102, and 103, and accordingly, the shooting module protection device is generally disposed in the terminal devices 101, 102, and 103. However, it is easily understood by those skilled in the art that the method for protecting the photographing module provided in the embodiment of the present disclosure may also be executed by the server 105, and accordingly, the photographing module protecting device may also be disposed in the server 105, which is not particularly limited in the exemplary embodiment.
For example, in an exemplary embodiment, a user may acquire light information in a current scene through a shooting module included in the terminal device 101, 102, 103 to generate an original image, and then upload the original image to the server 105, after the server generates a protection control instruction through the shooting module protection method provided by the embodiment of the present disclosure, the server transmits the protection control instruction to the terminal device 101, 102, 103, and the like, and the terminal device 101, 102, 103 drives a light shielding component related to the shooting module to weaken the intensity of incident light according to the protection control instruction.
In the related art, in order to avoid damage to the camera module caused by the laser, a laser scene is generally determined by a manual judgment method, and the intensity of light incident to a photosensitive element (such as a CMOS sensor) in the camera module is reduced by manually installing a dimmer. However, the protection scheme has a failure scene, for example, a user is exposed to a laser environment to talk and the like, and a shooting module is not started, and the user does not "perceive" the situation, but the laser can still burn the CMOS sensor; meanwhile, the laser damage time is very short, and often only the time of less than 5 seconds is needed, so that a CMOS sensor in the shooting module or a microlens on the surface of the CMOS sensor can be damaged, a certain delay exists in a manual judgment mode, the judgment accuracy for each scene is low, and manual operation is needed for installing the dimmer, so that a scene that the CMOS sensor is damaged but the dimmer is not installed can be caused.
Based on one or more problems in the related art, the present disclosure provides a method for protecting a shooting module first, and the following describes an exemplary embodiment of the method for protecting a shooting module in detail by taking a terminal device to execute the method as an example.
Fig. 2 shows a schematic flowchart of a protection method for a camera module in this exemplary embodiment, which may include the following steps S210 to S240:
in step S210, light irradiated to the photographing module is monitored, and a monitored image generated when the light is monitored is acquired.
In an exemplary embodiment, the shooting module refers to a module used for acquiring an image in the terminal device, for example, the shooting module may be a front camera module and/or a rear camera module of a smart phone, may also be a monitoring camera in a monitoring system, and may also be an image acquisition device configured on the smart robot for real-time drawing and navigation, and of course, the shooting module may also be another module existing in any form for acquiring an image, which is not particularly limited in this exemplary embodiment.
The light irradiated to the shooting module refers to any type of light beam irradiated to the shooting module in the current scene, for example, the light may be laser light directly irradiated to the shooting module by a laser device or laser light directly irradiated to the shooting module through other protection devices, or may be ambient light irradiated to the shooting module through specular reflection or diffuse reflection in the current scene, or may be irradiated to the shooting module in any other manner, and the contained energy is greater than the light of the preset energy threshold, which is not limited in this example embodiment.
It should be noted that the light mentioned in this embodiment generally refers to visible light with a light wavelength in a wavelength band of 380nm to 750 nm.
The monitor image refers to image data generated when light irradiating the shooting module is detected, specifically, the monitor image may be a Raw image output by an image sensor, i.e. a Raw image, the Raw image format is to capture (i.e. best performance of a specific sensor) shooting characteristics of a scene as much as possible, that is, physical information including illumination intensity and Color of a current scene, etc., and can contain more Raw data available for analysis than an image displayed to a user after processing, such as image sensor metadata (which may include size of the sensor, attribute of a Color Filter Array (Color Filter Array), Color profile, etc.), image metadata (which may include exposure parameters, camera/lens model, shooting date, etc.), image data (which may include brightness, white balance, hue, saturation, etc.), etc., this exemplary embodiment is not particularly limited to this.
The current scene can be continuously monitored through a low-power-consumption normally-on camera (AON) function, which is essentially in a low-frame-rate and low-pixel mode during the image production, for example, an original image can be output at a frame rate of 640 × 480 pixels and 5FPS (Frames Per Second), so that the purposes of low power consumption, small data volume and high processing speed can be achieved.
The acquired original image may be sent to a relevant computing Unit for analysis, for example, the acquired original image may be sent to a Central Processing Unit (CPU) for analysis, or may be sent to an embedded Neural Network Processor (NPU) for analysis, and the Processing Unit for Processing the original image is not particularly limited in this example embodiment. When the computing unit determines that an abnormal brightness area exists in the original image, the light irradiating the shooting module can be considered to be monitored, and the original image is used as a monitoring image generated when the light is monitored.
In step S220, the light type corresponding to the light is determined according to the monitoring image.
In an exemplary embodiment, the light type refers to a preset parameter that can be used to determine light classification in different scenes, for example, the light type may be a laser light type, a strong energy light type, a weak energy light type, or the like, and a specific light type may be set by a user according to different application scenes, which is not limited in this exemplary embodiment.
The light type corresponding to the light can be determined according to the distribution characteristics of the brightness values in the abnormal brightness area of the monitored image, for example, the abnormal brightness area generated when the laser light irradiates on the image sensor, wherein the distribution area of the larger brightness value is more concentrated, that is, the area of the high brightness spot is smaller, while the abnormal brightness area generated when the ordinary incandescent lamp light irradiates on the image sensor, wherein the brightness values are uniformly distributed and the more concentrated high brightness spot area does not exist. Of course, an Infrared Radiation (IR) component corresponding to the light may also be extracted according to the monitored image, and the light type corresponding to the light may be determined according to the IR component.
In step S230, in response to determining that the ray type is the target ray type, a protection control instruction is generated.
In an exemplary embodiment, the target light type refers to a light type that may cause damage to the photographing module, for example, it is assumed that the set target light types include a laser light type, a strong energy light type, and a weak energy light type, wherein the laser light type and the strong energy light type may cause burning to a photosensitive element (e.g., a CMOS sensor) in the photographing module, and thus, the laser light type and the strong energy light type may be set as the target light types.
The protection control command is a command generated based on light data acquired from the monitored image and the determined target light type, and is used for driving the shading assembly to adjust the light intensity of the light entering the shooting module, and the protection control command may include, but is not limited to, the target light type, IR component data, light intensity data, and light wavelength data corresponding to the light.
In step S240, the light shielding assembly associated with the shooting module is driven by the protection control command, so as to adjust the light intensity of the light incident to the shooting module according to the light shielding assembly.
In an exemplary embodiment, the light shielding component refers to a component for blocking a light path or reducing light intensity/light energy, for example, the light shielding component may be a light barrier made of an opaque material, may also be an electrochromic lens having a function of adjusting light transmittance, and may also be an iris structure capable of reducing incident amount of light, of course, the light shielding component may also be any other type of component capable of blocking a light path or reducing light intensity/light energy, which is not limited in this exemplary embodiment.
The shading component can be integrated in the terminal device, for example, the shading component can be integrated in the shooting module, such as between an optical lens and an image sensor in the shooting module, or the shading component can be integrated on a main board of the terminal device, such as between the shooting module and a housing of the terminal device; of course, the light shielding assembly may also be an external device, and is disposed on the terminal device housing in a wired connection or wireless connection manner, for example, the light shielding assembly may be disposed at the light inlet of the shooting module on the terminal device housing.
The light shielding assembly may be composed of only one component, for example, the light shielding assembly may be composed of a light barrier, an electrochromic lens, or an iris structure, and of course, the light shielding assembly may also be composed of any two components of the light barrier, the electrochromic lens, and the iris structure, or may also be composed of three components of the light barrier, the electrochromic lens, and the iris structure, and the configuration of the light shielding assembly in this exemplary embodiment is not particularly limited.
The following describes steps S210 to S240 in detail.
In an exemplary embodiment, the shooting module may be controlled to continuously output the original image at a low frame rate, and in response to detecting that a target brightness region exists in the current original image, it is determined that light irradiating the shooting module is monitored, and the current original image is used as a monitored image generated when the light is monitored.
The target luminance area refers to an area in which light is irradiated in the current original image, for example, the target luminance area may be an area in which a luminance value is concentrated, or may be an area in which a peak value of a luminance value is greater than a preset luminance value, which is not particularly limited in this example embodiment. When the target brightness area is detected in the current original image, it can be considered that abnormal light exists in the current scene, further detection and analysis are needed, and the current original image is used as a monitored image corresponding to the monitored light.
Specifically, the function of Always on camera (AON) with low power consumption may be turned on, and the shooting module is controlled by the function logic to continuously output the corresponding original image in the current scene in a low frame rate and low pixel mode, for example, the original image may be output at a frame rate of 640 × 480 pixels and 5FPS (Frames Per Second), or may be output at a frame rate of 240 × 160 pixels and 20FPS, and specifically, the custom setting may be performed according to the actual application scene, which is not limited in this example embodiment.
When it is determined that the target brightness area exists in the output current original image, it can be considered that the light irradiating the shooting module is monitored at the current moment, and the current original image is used as a monitoring image generated when the light is monitored.

Referring to fig. 3, the terminal device may be a smart phone 301, the shooting module 302 may be a rear camera module of the smart phone 301, specifically, the rear camera module may include a shooting module 302 for collecting image data and a light shielding component 303 associated with the shooting module 302, and the light shielding component 303 may be disposed at a position near the shooting module 302, for example, the light shielding component 303 may be disposed between an optical lens and an image sensor in the shooting module 302, and may be disposed between the shooting module 302 and a terminal device housing; of course, the light shielding component may also be disposed on the terminal device housing, for example, the light shielding component may be disposed at the light inlet of the shooting module 302 on the terminal device housing, and the embodiment is not limited thereto. For convenience of illustration, fig. 3 is drawn by taking the light inlet of the shooting module 302 disposed on the housing of the terminal device as an example, and no particular limitation should be imposed on the embodiment.
In the laser irradiation scene, the laser beam emitted by the laser device 304 irradiates the shooting module 302 during scanning. When a laser beam irradiates the shooting module 302, the terminal device may turn on the AON function, control the image sensor 305 of the shooting module 302 to output the original image 306 in the form of low frame rate and low pixels, and transmit the original image 306 to the computing unit for analysis processing, when detecting that the target brightness region 307 appears in the original image 306, may determine that an abnormal light exists in the current scene, and the abnormal light irradiates the shooting module 302, and perform subsequent processing with the original image 306 as a monitoring image generated when the light is monitored.
