Fig. 1 is a schematic flowchart of a shooting method according to an embodiment of the present disclosure. The method may be performed by a camera, which may be implemented in software and/or hardware. The shooting device can be configured in an electronic device, such as a terminal, specifically including but not limited to a smart phone, a palm computer, a tablet computer, a wearable device with a display screen, a desktop computer, a notebook computer, an all-in-one machine, a smart home device, and the like.
As shown in fig. 1, the shooting method provided by the present embodiment includes the following steps:
and step 110, determining the brightness of the current shooting scene based on the corresponding relation between the photosensitive value of the main camera and the scene brightness and/or based on the corresponding relation between the photosensitive value of the night vision camera and the scene brightness.
In one embodiment, determining the brightness of the current shooting scene based on the corresponding relationship between the photosensitive value of the main camera and the scene brightness and/or based on the corresponding relationship between the photosensitive value of the night vision camera and the scene brightness comprises:
determining first brightness based on the corresponding relation between the photosensitive value of the main camera and the scene brightness;
determining second brightness based on the corresponding relation between the photosensitive value of the night vision camera and the scene brightness;
and determining the average value of the first brightness and the second brightness as the brightness of the current shooting scene.
The number of pixels of the main camera is higher than that of the night vision camera, and the size of a single pixel of the main camera is smaller than that of a single pixel of the night vision camera. The main camera has higher number of pixels, is applicable to bright environment and the dark environment that has certain light, demonstrates high image quality, nevertheless because the number of pixels is higher, the size of single pixel is less, has reduced the shooting quality of main camera in extremely dark environment by a wide margin. Aiming at the problem, in the embodiment of the application, besides the main camera, a night vision camera is further arranged, the number of pixels of the night vision camera is lower than that of the main camera, and the size of a single pixel is larger, so that the brightness of an extremely dark environment can be greatly improved, and the defect that only the main camera is used for night vision algorithm is overcome. For example, the night vision camera can be an infrared camera with 200 ten thousand pixels, and f/1.8 large aperture and large-size pixels can greatly improve the brightness of an extremely dark environment, so as to shoot and obtain an image with higher picture quality.
Further, in an embodiment, the determining the brightness of the current shooting scene based on the corresponding relationship between the photosensitive value of the main camera and the brightness of the scene and/or based on the corresponding relationship between the photosensitive value of the night vision camera and the brightness of the scene includes:
determining first brightness based on the corresponding relation between the photosensitive value of a main camera and scene brightness, and determining the first brightness as the brightness of the current shooting scene;
or determining second brightness based on the corresponding relation between the photosensitive value of the night vision camera and the scene brightness, wherein the second brightness is determined as the brightness of the current shooting scene.
In order to enable the photosensitive value of each camera to accurately reflect the scene brightness (namely the light intensity), a certain number of modules can be collected, a proportion graph between the photosensitive value and the scene brightness is drawn, and the corresponding scene brightness can be determined based on the photosensitive value through the proportion graph.
For example, if the currently corresponding enabled camera (which represents a camera that can be used to take a picture) is the main camera, the brightness of the current shooting scene may preferably be determined based on the exposure value of the main camera. If the current corresponding enabling camera is a night vision camera, the brightness of the current shooting scene can be preferably determined based on the photosensitive value of the night vision camera, so that the back-and-forth switching between the main camera and the night vision camera is avoided, the service life of the camera is shortened, and the electric quantity consumption of the terminal is increased. Specifically, for example, if the currently corresponding enabled camera is the main camera and the shooting program sets that the brightness of the current shooting scene is determined based on the light sensitivity value of the night vision camera, the main camera of the current enabled camera needs to be switched to the night vision camera, and then the brightness of the current shooting scene is determined based on the light sensitivity value of the night vision camera. On the contrary, for example, if the currently corresponding enabled camera is a night vision camera and the shooting program is set to determine the brightness of the current shooting scene based on the light sensing value of the main camera, the current enabled camera needs to be switched from the night vision camera to the main camera, and then the brightness of the current shooting scene is determined based on the light sensing value of the main camera, thereby increasing the operation steps undoubtedly.
Or, if the brightness of the current shooting scene is determined to be low through the enabling camera (for example, the main camera), the night vision camera needs to be switched to the enabling camera, that is, the night vision camera is switched to be used, the brightness of the current shooting scene can be further determined through the photosensitive value of the night vision camera after the switching, so as to verify whether the brightness of the current shooting scene determined through the main camera is accurate or not, and if the brightness is not accurate, the enabling camera is timely switched, so that the purpose of improving the brightness determination precision is achieved. Similarly, if it is determined that the brightness of the current shooting scene is high through the enabling camera (for example, the night vision camera), the main camera needs to be switched to the enabling camera, that is, the main camera is switched to be used, the brightness of the current shooting scene can be further determined through the photosensitive value of the main camera after the switching, so as to verify whether the brightness of the current shooting scene determined through the night vision camera is accurate, and if not, the enabling camera is switched in time. Furthermore, the brightness of the current shooting scene can be determined based on the average value of the brightness respectively determined by the two cameras, so that the determination precision of the brightness is improved, a reference basis is further provided for determining the current enabled camera, and a basis is provided for obtaining a high-quality shooting image.
And step 120, determining a target camera from the main camera and the night vision camera according to the brightness.
Specifically, if the brightness of the current shooting scene is high, that is, the light intensity is good, the main camera with high pixels is used for shooting to obtain a high-quality shooting image. If the brightness of the current shooting scene is low, namely the light intensity is not good, the night vision camera with lower pixels is used for shooting, so that the size of a single pixel is improved by reducing the number of pixels, the brightness of an extremely dark environment is improved, and finally a shooting image with better image quality is obtained.
In one embodiment, determining a target camera from a main camera and a night vision camera based on the brightness includes:
if the brightness reaches a set threshold value, determining that a main camera is the target camera;
and if the brightness does not reach the set threshold value, determining that the night vision camera is the target camera.
And step 130, shooting the current shooting scene through the target camera.
It can be understood that each camera is configured with a common multi-frame noise reduction algorithm, for example, the main camera is configured with a multi-frame noise reduction algorithm suitable for a bright environment, the night vision camera is configured with a multi-frame noise reduction algorithm suitable for a dark environment, and different cameras are used for shooting in environments with different brightness by configuring two cameras, so that each camera plays respective advantages in a specific shooting environment, the adaptability to the dark environment is stronger and wider, and the problem that the main camera and the night vision algorithm cannot obtain clear images in an extremely dark environment is solved.
According to the technical scheme, different cameras are used for shooting according to the brightness of the current shooting scene, the image quality of the shot image is improved, and especially under the environment with extremely dark brightness, the image quality can be greatly improved.
Fig. 2 is a schematic flowchart of another shooting method according to an embodiment of the present disclosure. On the basis of the foregoing embodiment, this embodiment provides an optional implementation manner for the foregoing step 120 "determining the target camera from the main camera and the night vision camera according to the brightness", specifically, in order to prevent frequent switching between the main camera and the night vision camera, a switching trigger condition is set so as to improve the service life of the shooting device and reduce power consumption caused by switching operation. The same or similar contents as those in the above embodiments are not repeated in this embodiment, and for the related explanation, reference may be made to the above embodiments.
As shown in fig. 2, the method comprises the steps of:
step 210, determining the brightness of the current shooting scene based on the corresponding relation between the photosensitive value of the main camera and the scene brightness and/or based on the corresponding relation between the photosensitive value of the night vision camera and the scene brightness.
Step 220, if the brightness of the picture with the preset frame number is continuously monitored to be lower than a first preset value through the main camera, switching to using a night vision camera; and if the brightness of the picture with the preset frame number is continuously monitored to be higher than a second preset value through the night vision camera, switching to use the main camera.
For example, if the brightness of the picture continuously monitored by the main camera at 20-30fps (Frames Per Second) is lower than 20lux, the night vision camera is switched to be used. And if the brightness of the picture of 20-30fps is continuously monitored to be higher than 50lux through the night vision camera, switching to use the main camera. The scene brightness interval during the first two shot switches is temporarily marked, and the shot delay switch is performed on the scene brightness interval falling into the temporary mark in a short time (for example, 30s) so as to avoid frequent and mistaken shot switch.
And step 230, shooting the current shooting scene through the target camera.
Further, in order to reduce the probability of false switching and the switching frequency, the method for determining the target camera from the main camera and the night vision camera according to the brightness further comprises the following steps:
marking a scene brightness interval during the first shot switching and a scene brightness interval during the second shot switching to obtain a marked scene brightness interval;
if the brightness of the picture continuously monitored by the main camera with the preset frame number is lower than a first preset value, or the brightness of the picture continuously monitored by the night vision camera with the preset frame number is higher than a second preset value, but the brightness of the current shooting scene falls in the marked scene brightness interval, the operation of switching to the use of the night vision camera is executed after the set time is delayed, or the operation of switching to the use of the main camera is executed after the set time is delayed.
The scene brightness interval during the first lens switching comprises a scene area brightness interval during the first switching to use the night vision camera, or a scene area brightness interval during the first switching to use the main camera. Correspondingly, the scene brightness interval during the second shot switching comprises the scene area brightness interval during the first switching to the use of the main camera, or the scene area brightness interval during the first switching to the use of the night vision camera.
For example, the first lens switching to the first switching to use the night vision camera indicates that the enabled camera before the lens switching is the main camera, the first lens switching is to use the night vision camera, that is, the enabled camera after the switching is the night vision camera, and then the second lens switching is to use the main camera, that is, the main camera after the switching is the enabled camera. The number of times is counted in a cycle starting when the image pickup application is started and ending when the image pickup application is closed.
Specifically, for example, when the enabled camera is a night vision camera when the camera application is started, the first shot switching finger switches to use the main camera for the first time, and the corresponding second shot switching finger switches to use the night vision camera for the first time before the camera application is closed.
In the technical solution of the embodiment of the present application, on the basis of the above embodiment, an optional implementation manner is provided for the step 120 "determining the target camera from the main camera and the night vision camera according to the brightness", specifically, in order to prevent frequent switching between the main camera and the night vision camera, a switching trigger condition is set so as to improve the service life of the shooting device and reduce power consumption caused by switching operation.
Taking the example that the shooting device is integrated in a smart phone, the shooting process of the shooting method is explained from the product side:
as shown in fig. 3, the interface schematic diagram after the camera application is started includes a night view option, a default mode of the night view option is automatic, that is, lens switching is started in a preview stage according to brightness of a current shooting scene, specifically, when it is continuously monitored by a main camera that brightness of a picture with a preset frame number is lower than a first preset value, switching is performed to use a night view camera; and if the brightness of the picture with the preset frame number is continuously monitored to be higher than a second preset value through the night vision camera, switching to use the main camera.
Illustratively, when the camera identification 310 in fig. 3 is highlighted in blue, it indicates that the current enabled camera is a night vision camera, and when the camera identification 310 is highlighted in white, it indicates that the current enabled camera is a main camera. If the user triggers the night scene "turn on" identifier 320, the enabled camera is resident as a night vision camera, namely shooting is performed through the night vision camera, and automatic switching is not performed along with scene brightness. If the user triggers the night scene closing identifier 330, the enabled camera is resident as the main camera, that is, shooting is performed through the main camera, and automatic switching is not performed along with the scene brightness.
In an embodiment, referring to a schematic flow chart of a shooting method shown in fig. 4, the method specifically includes:
step 1, obtaining the brightness of the current shooting scene.
And 2, judging the target camera adaptive to the brightness of the current shooting scene by a brightness detection algorithm.
And step 3, enabling the target camera.
And 4, configuring a night scene algorithm of the target camera.
In step 1, the brightness of the current shooting scene can be obtained through the sensitivity ISO of the currently enabled camera, and when the light is good, low sensitivity is used, and when the light is poor, high sensitivity is used. On the basis of the original single-camera night scene algorithm, the main camera and the night vision camera are used for working cooperatively under different scene brightness, and respective night scene algorithms are configured, so that noise points of output images can be removed, and the definition is improved. The main camera has high pixel number, can show high image quality under bright environment and dark environment with certain light, but the single pixel size is little, has reduced image shooting quality under the extremely dark environment by a wide margin. The night vision camera has a large aperture and large-size pixels, so that the brightness of an extremely dark environment can be greatly improved, the image quality of the image in the extremely dark environment can be greatly improved, and the defect of a single camera night scene algorithm is overcome.
Optionally, the target camera which is adapted to the brightness of the current shooting scene can be determined by combining the scene brightness and the specific environment to determine which camera is specifically adopted by pre-training the neural network model in an artificial intelligence AI manner. The switching camera can also consider adding a fusion algorithm so as to smooth the switching process and improve the use experience of a user.
