Technical Field
The present disclosure relates to the field of image acquisition control, and more particularly, to a camera control method, a camera control device, an image acquisition apparatus, and an electronic apparatus.
Background
Currently, more and more electronic devices are equipped with cameras so as to have an image capturing function. For example, a mobile phone with a digital camera function can take still pictures or video through a built-in or external camera. With the improvement of the pixels of the camera, the shooting effect of the camera is closer to that of the traditional card camera and even a low-end single-lens reflex camera, so that the camera is rapidly popularized.
In order to facilitate shooting, when the cameras are installed on electronic equipment, the cameras are usually directly exposed to the air, and even if a camera cover and the like are used for protection, the cameras can also be directly exposed to the air in the working process. Since some dust is always present in the air, the dust is likely to scatter on the surface of the camera, so that the image of the camera looks blurred.
At present, only in the case that the image of the camera is found to be blurred, whether the surface is covered by dust is checked, and if the dust is found, the dust covered on the surface of the camera is cleaned by using soft cotton cloth or the like, or cleaned by using glasses cloth or professional lens paper or the like, and the image shot by the user through the camera is also blurred.
The manual visual observation mode easily causes the judgment to be not accurate enough, and the camera is not intelligent and automatic enough in use, so that the imaging is not clear.

Detailed Description
Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein.
Summary of the application
As described above, at present, whether dust exists on the surface of the camera is judged by observing the surface of the camera through naked eyes, and whether the dust can cause unclear imaging. However, the manner of manual and visual judgment easily results in inaccurate judgment, thereby causing unclear imaging.
That is, the camera is not intelligent and automated enough in use control for dust.
In view of the above technical problem, a basic idea of the present application is to provide a dust detection state that enables control of a camera to detect an amount of dust on a surface of the camera, thereby controlling a state of the camera based on the detected amount of dust.
Specifically, the camera control method, the camera control device, the image acquisition equipment and the electronic equipment provided by the application firstly control the camera to be in a dust detection state, then detect the dust amount on the surface of the camera in the dust detection state, and finally control the state of the camera based on the dust amount.
Therefore, the camera control method, the camera control device, the image acquisition equipment and the electronic equipment provided by the application can detect the dust amount on the surface of the camera through controlling the camera to be in a dust detection state, can realize the self-checking function of the dust amount of the camera, and realize accurate dust judgment in a mode of manual visual observation.
In addition, the camera control method, the camera control device, the image acquisition equipment and the electronic equipment provided by the application control the state of the camera based on the dust amount, so that the problem of unclear imaging caused by dust can be avoided, and corresponding intelligent and automatic control is realized.
Having described the general principles of the present application, various non-limiting embodiments of the present application will now be described with reference to the accompanying drawings.
Exemplary method
Fig. 1 illustrates a flowchart of a camera control method according to an embodiment of the present application.
As shown in fig. 1, a camera control method according to an embodiment of the present application includes: s110, controlling the camera to be in a dust detection state; s120, detecting the dust amount on the surface of the camera in the dust detection state; and S130, controlling the state of the camera based on the dust amount.
In step S110, the camera is controlled to be in a dust detection state. Next, different states of the camera in the embodiment of the present application will be explained with reference to fig. 2.
Fig. 2 illustrates a schematic diagram of different states of a camera according to an embodiment of the application. As shown in fig. 2 (a), when the camera C needs to perform shooting, the camera is located outside the completely sealed shield H for dust detection or the like, and as shown in fig. 2(B), when the camera C needs to perform dust detection, the camera is controlled to move inside the shield H, i.e., the completely sealed dust detection position PD, and is turned on for dust detection. That is, in the embodiment of the present application, the dust detection state is different from a normal operation state when the camera performs shooting.
Therefore, in the camera control method according to the embodiment of the present application, controlling the camera in the dust detection state includes: controlling the camera to move to a completely closed dust detection position; and controlling the camera to be opened at the dust detection position so as to be in the dust detection state.
That is, as shown in fig. 2(B), the camera C is turned on at a fully-closed dust detection position PD inside the hood H to perform dust detection.
In step S120, in the dust detection state, the amount of dust on the camera surface is detected. That is, as shown in fig. 2(B), when the camera is moved to the dust detection position PD within the hood H, a dust self-detection function of the camera is performed to detect the amount of dust on the surface of the camera.
In the embodiment of the present application, the dust amount on the surface of the camera can be detected by acquiring a picture taken by the camera and performing image processing on the picture, which will be described in further detail below.
In step S130, the state of the camera is controlled based on the amount of dust. Specifically, in the embodiment of the present application, the camera may be controlled to be in different states based on the amount of the dust.
For example, a predetermined threshold value for determining whether the dust amount of the camera affects normal operation may be set, so that when the detected dust amount is less than or equal to the predetermined threshold value, the camera is controlled to be activated to enter an operating state. For example, referring to fig. 2 (a) and (B), when the camera C is activated to perform the operating state, the camera moves from a dust detection position PD for detecting the amount of dust to an operating position PW for normally capturing an image.
When the detected dust amount is larger than the predetermined threshold, it indicates that the camera cannot normally operate due to the influence of the dust amount on the surface, otherwise, the problem of unclear image or the like is caused. Accordingly, the camera can be controlled to be turned off at this time to enter a power-off state. In the power-off state, the surface of the camera may be cleaned, for example, manually or automatically.
For example, as shown in (C) of fig. 2, when the detected dust amount is larger than the predetermined threshold value and the camera C needs to be cleaned, the camera is controlled to move from the dust detection position PD to the cleaning position PC. In this way, in the cleaning position PC, the camera cleaning device can be controlled to clean the camera in the cleaning position.
In the embodiment of the present application, the specific type and operation mode of the camera cleaning device are not limited. In one example, as shown in fig. 3, the camera cleaning device may include a water tank T and an ultrasonic vibration module S. And, the water tank includes a lens connection port Ic. Here, it is understood by those skilled in the art that the water tank also includes a water inlet and a water outlet, etc., although not shown in fig. 3. In this way, when the camera is accommodated in the water tank through the lens connection port I, the ultrasonic vibration module S emits ultrasonic waves to vibrate water in the water tank T, thereby cleaning the surface of the camera. Fig. 3 illustrates a schematic view of a camera cleaning device according to an embodiment of the application.
In addition, in the embodiment of the present application, the camera cleaning device may include a soft fabric for cleaning the surface of the camera and a moving device for moving the soft fabric, so that the surface of the camera is cleaned by the soft fabric. Here, as can be appreciated by those skilled in the art, in addition to moving the soft fabric, the moving means may also move the camera so that the surface of the camera moves relative to the soft fabric to clean the surface of the camera.
In addition, when the dust amount is detected to be larger than the preset threshold value, when the camera cannot work normally, an alarm can be sent to a user to prompt the user that the camera cannot work normally, that is, the camera can be controlled to be in a dust alarm state.
It should be noted that, in the embodiment of the present application, the camera may be always turned on, and the detected dust amount may be notified to the user by a quantitative value. For example, the size of the detected dust amount is divided into 10 ranks of 1 to 10, and the user is notified of the detected rank scores, so that the user can decide by himself whether to continue shooting with the camera.
Fig. 4 illustrates a flow chart of a dust detection process according to an embodiment of the application.
As shown in fig. 4, on the basis of the embodiment shown in fig. 2, the step S120 may include the following steps:
step S1201, controlling a light source to uniformly irradiate the camera with light. When the camera C is located at the dust detection position PD, as shown in fig. 2(B), the dust detection device is connected to the dust detection device through a camera connection port Id shown in fig. 5. The means for dust detection comprises a light source Y that emits light to illuminate the camera with a light beam L. Fig. 5 illustrates a schematic diagram of a camera dust detection apparatus according to an embodiment of the present application.
As further shown in fig. 5, in the case where the light source Y is a point light source, in order to allow the light source Y to uniformly irradiate the camera with light, a diffusion sheet D is included between the light source and the camera to diffuse the light beams emitted from the light source. Of course, it will be understood by those skilled in the art that the light source may also be implemented as a surface light source for uniformly illuminating the camera without a diffusion sheet.
And step S1202, acquiring the image shot by the camera. In the case where the light source illuminates the camera, the camera takes an image and acquires the image for determining the amount of dust through image analysis.
Step S1203 detects an amount of dust on the surface of the camera based on the image. Next, how to detect the amount of dust on the surface of the camera by analyzing the image taken by the camera will be described with reference to fig. 6.
In this way, through the dust detection process as shown in fig. 4, the dust amount on the surface of the camera can be automatically detected without the help of artificial visual observation, thereby avoiding the error observed by human eyes and realizing accurate dust detection.
Fig. 6 illustrates a flow chart of a dust-image analysis process according to an embodiment of the present application.
As shown in fig. 6, on the basis of the embodiment shown in fig. 4, the step S1203 may include the following steps:
step S12031, determining an area of a patch in the image. That is, as shown in fig. 7, when the camera takes an image by the camera dust detection device as described above, if the camera surface is free from dust, a pure white image will be obtained. Whereas if the camera surface has dust, a patch having a gray scale may exist in an image photographed by the camera due to the influence of the dust. Therefore, in order to determine the amount of dust on the camera surface, the area of the patch in the image is first determined. Fig. 7 illustrates a schematic view of a dust image captured by a camera according to an embodiment of the present application.
Step S12032, determining a ratio of the area of the patch to the total area of the image. That is, the area of the patch in the image depends on the amount of dust on the camera surface and the total area of the image, and by determining the ratio of the area of the patch to the total area of the image, the amount of dust on the camera surface can be determined accordingly.
Step S12033, detecting the amount of dust on the camera surface based on the ratio. That is, when the area ratio is large, it can be determined that the amount of dust on the camera surface is large, and when the area ratio is small, it can be determined that the amount of dust on the camera surface is small.
It is to be noted that, in the embodiment of the present application, in addition to the ratio, other image parameters, such as the gradation value of each patch, may be further considered to detect the amount of dust on the camera surface. For example, when the gray value of a patch is large, it indicates that the amount of dust corresponding to the patch is large, and when the gray value of the patch is small, it indicates that the amount of dust corresponding to the patch is small.
In this way, through the dust image analysis process shown in fig. 6, quantitative data of the dust amount on the surface of the camera can be obtained through image analysis, so that an accurate dust amount value is obtained, and the automation and intelligent control level of the camera is further improved.
As described above, in the embodiment of the present application, when the amount of dust on the surface of the camera exceeds the predetermined threshold value and thus cannot normally operate, the camera may be cleaned using the camera cleaning device. Thereafter, in order to detect the cleaning result of the camera, the camera may be further controlled to be in a dust detection state, and the amount of dust on the surface of the camera may be detected.
FIG. 8 illustrates a flow chart of a camera dust detection and cleaning process according to an embodiment of the application.
As shown in fig. 8, in step S201, the camera is first controlled to be in a dust detection state, for example, as shown in (B) of fig. 2. Then, in step S202, the amount of dust on the camera surface is detected in the manner described above. In step S203, in response to the camera dust detection being qualified, that is, the amount of dust being less than or equal to a predetermined threshold, the camera is controlled to enter an operating state, for example, as shown in (a) of fig. 2. Then, in step S204, after the end of the operation, the camera is brought into a standby state. It is to be noted that, in the embodiment of the present application, when the camera is started up again from the standby state, the dust detection state may be entered first to avoid unclear imaging.
In addition, in step S205, in response to the camera dust detection failing, that is, the amount of dust being greater than a predetermined threshold, the camera is controlled to enter a cleaning state, for example, as shown in (C) of fig. 2. After the cleaning is finished, the camera can be directly controlled to enter the working state, namely, the step S203 is reached. Alternatively, the camera may be controlled to be in the dust detection state again to detect whether the cleaning effect of the camera meets the requirement, i.e., returning to step S201.
Therefore, through the camera dust detection and cleaning process as shown in fig. 8, dust self-checking and automatic cleaning of the camera and intelligent starting of the camera based on dust amount can be realized, so that the automation and intelligence degree of the camera are improved.
