Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.
With the development of the terminal industry, at present, cameras of terminal devices (such as smart phones, palm computers, notebooks, digital cameras, etc.) basically adopt Complementary Metal Oxide Semiconductor (CMOS) sensors, and when exposure time is not an integral multiple of a light flicker period, flicker, that is, power frequency interference, is generated at this time.
It can be understood that Flicker refers to a picture Flicker phenomenon generated when a camera acquires an image under a fluorescent lamp as a light source, and is specifically shown in fig. 1A and 1B; where fig. 1A provides an example of an image containing band noise (flicker) and fig. 1B provides an example of an image not containing band noise (flicker). The fundamental reason for this flicker is caused by different light energies emitted by the light source to different pixels, and the light energies received by different pixels are different, so that the brightness of the image is also different. At present, more two power supply frequencies are used, namely 50Hz and 60 Hz; here, 50Hz is mainly applied to regions such as mainland china, and 60Hz is mainly applied to regions such as taiwan, japan, and the like. Because the exposure mode of the CMOS sensor is carried out line by line, when the exposure time is not integral multiple time of the light energy period, the phenomenon of flicker is generated at the moment. To prevent the flicker phenomenon, current solutions set the exposure parameters separately for these two frequencies; if the current environment is detected to be under the frequency of a 50Hz light source, the exposure parameters based on 50Hz are adopted at the moment; if the current environment is detected to be at the 60Hz light source frequency, the exposure parameters based on 60Hz are adopted at the moment.
However, in the current solution, it is possible to determine whether to use the exposure parameter based on 50Hz or 60Hz according to external variables such as the location of the apparatus and the country of distribution, etc., in order to prevent the flicker phenomenon. However, the solution cannot cope with more user use environments, and the final use environment of the user is not guaranteed as a result of the external variable, which easily causes the phenomenon that the exposure parameter is not matched with the use environment, so that the flicker phenomenon is still generated, and the user experience is affected.
The embodiment of the application provides an exposure control method which is applied to terminal equipment. When a camera of the terminal equipment is started, acquiring the current ambient light frequency; then judging whether the terminal equipment is in a standard environment or not according to the current environment light frequency; if the terminal equipment is in a non-standard environment, determining a target exposure parameter according to the current ambient light frequency; controlling the exposure of the camera based on the determined target exposure parameter; therefore, by judging whether the terminal equipment is in the standard environment or not, when the terminal equipment is in the non-standard environment, the target exposure parameter is determined according to the current ambient light frequency, namely, the target exposure parameter is determined according to the current ambient light frequency only aiming at the non-standard environment, so that misoperation in the standard environment can be effectively avoided; and for the non-standard environment, different environmental light frequencies adopt different exposure parameters, so that the phenomenon of flicker caused by mismatching of the exposure parameters and the current environment due to single exposure parameters can be effectively prevented, and the shooting effect of the image is improved.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
In an embodiment of the present application, referring to fig. 2, a flowchart of an exposure control method provided in an embodiment of the present application is shown. As shown in fig. 2, the method may include:
s201: when a camera of the terminal equipment is started, acquiring the current ambient light frequency;
it should be noted that the method is applied to the terminal device, and the terminal device includes a camera. The terminal device may be described in any form, for example, the terminal device described in the embodiment of the present application may include a mobile terminal such as a smart phone, a tablet computer, a notebook computer, a palm computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a Digital camera, a video camera, and a fixed terminal such as a Digital TV, a desktop computer, and the like, and the embodiment of the present application is not particularly limited.
It should be noted that the current ambient light frequency refers to the ambient light frequency at which the terminal device is currently located. Therefore, when a camera of the terminal device is started, the current ambient light can be collected through the color temperature sensor so as to obtain the current ambient light frequency. Therefore, in some embodiments, for S201, the acquiring the current ambient light frequency may include:
and acquiring the current ambient light frequency through the configured color temperature sensor.
That is, the terminal device is also internally provided with a color temperature sensor, and the color temperature sensor may be placed near the camera. Therefore, when the camera is started, the current ambient light frequency can be acquired through the color temperature sensor.
Specifically, the color temperature sensor can continuously acquire the frequency of the ambient light and can also periodically acquire the frequency of the ambient light; the acquisition period may be set according to an actual situation, but the embodiment of the present application is not particularly limited.
S202: judging whether the terminal equipment is in a standard environment or not according to the current ambient light frequency;
after obtaining the current ambient light frequency, it may be determined whether the terminal device is in the standard environment according to the current ambient light frequency. The standard environment may refer to an ambient light frequency within a frequency range of 50Hz to 60Hz, or may refer to an ambient light frequency within a wider frequency range, for example, a frequency range of 40Hz to 70Hz, but the embodiment of the present application is not limited specifically.
Specifically, by comparing the current ambient light frequency with the preset frequency range, it can be determined whether the terminal device is in the standard environment. Therefore, in some embodiments, for S202, the determining whether the terminal device is in a standard environment may include:
comparing the current ambient light frequency with a preset frequency range;
if the current ambient light frequency is within the preset frequency range, determining that the terminal equipment is in a standard environment;
and if the current ambient light frequency is out of the preset frequency range, determining that the terminal equipment is in a non-standard environment.
It should be noted that the preset frequency range represents a preset frequency range conforming to a standard environment. The preset frequency range may be set to 50Hz to 60Hz, or may be set to 40Hz to 70Hz, but the setting of the preset frequency range is set according to actual situations, and the embodiment of the present application is not particularly limited.
Therefore, after the ambient light frequency is acquired, the current ambient light frequency can be compared with the preset frequency range, and if the current ambient light frequency is within the preset frequency range, the terminal device can be indicated to be in the standard environment currently; if the current ambient light frequency is outside the preset frequency range, the terminal device can be indicated to be in the non-standard environment currently. For example, assuming that the preset frequency range is 40Hz to 70Hz, if the current ambient light frequency is 55Hz, the current environment of the terminal device is a standard environment because 55Hz is within the preset frequency range; if the current ambient light frequency is 35Hz, the fact that 35Hz is out of the preset frequency range indicates that the environment where the terminal device is currently located is a non-standard environment.
S203: if the terminal equipment is in a non-standard environment, determining a target exposure parameter according to the current ambient light frequency;
before determining the target exposure parameter according to the current ambient light frequency, the terminal device needs to store a mapping relationship between the ambient light frequency and the exposure parameter in advance. Thus, in some embodiments, the method may further comprise:
determining exposure parameters respectively corresponding to different ambient light frequencies;
and establishing and storing a mapping relation between the ambient light frequency and the exposure parameter.
It should be further noted that the mapping relationship between the ambient light frequency and the exposure parameter may be obtained in an experimental manner before the terminal device leaves the factory, and then written into the storage area of the terminal device. That is, before the terminal device leaves the factory, exposure parameters corresponding to different ambient light frequencies can be determined based on an experimental mode; here, the experimental mode may be that an initial display effect of the camera when the camera is started under different exposure parameters is tested at a certain fixed ambient light frequency, an optimal exposure parameter is determined based on the initial display effect of the camera when the camera is started under different exposure parameters, and the optimal exposure parameter is used as the exposure parameter corresponding to the fixed ambient light frequency; by the method, exposure parameters corresponding to different ambient light frequencies can be obtained; after the exposure parameters respectively corresponding to different ambient light frequencies are determined, a mapping relation between the ambient light frequencies and the exposure parameters can be established and stored in a storage area of the terminal device.
Further, when the terminal device is in a non-standard environment, the target exposure parameter corresponding to the current ambient light frequency may be determined according to a mapping relationship between the ambient light frequency and the exposure parameter. Thus, in some embodiments, for 203, the determining a target exposure parameter according to the current ambient light frequency may include:
inquiring an exposure parameter corresponding to the current ambient light frequency according to a mapping relation between the pre-stored ambient light frequency and the exposure parameter;
and determining the inquired exposure parameters as the target exposure parameters.
It should be noted that, when the terminal device is in a non-standard environment, the target exposure parameter needs to be set according to the current ambient light frequency at this time. Specifically, from a mapping relationship between the pre-stored ambient light frequency and the exposure parameter, an exposure parameter corresponding to the current ambient light frequency is queried, and then the queried exposure parameter is determined as the target exposure parameter.
In the embodiments of the present application, the exposure parameters include at least an exposure time. Whether the flicker phenomenon exists or not can be judged according to the difference of the exposure time; i.e., when the exposure time is not an integer multiple of the light energy period, there will be a flicker phenomenon at this time. Thus, the current ambient light frequency can be obtained to determine the target exposure parameter according to the mapping relation between the ambient light frequency and the exposure parameter; wherein, the target exposure parameters at least comprise target exposure time; that is, by adjusting the exposure time to the target exposure time, the flicker phenomenon can be effectively prevented. In addition, the exposure parameters may also include an exposure value, an aperture, and the like, and the embodiment of the present application is not particularly limited.
S204: controlling the camera exposure based on the determined target exposure parameters.
It should be noted that after the target exposure parameter is determined, the exposure of the camera can be controlled according to the target exposure parameter, so that the exposure parameter is matched with the current environment, the flicker phenomenon can be prevented, an image with a good effect can be shot, and the user experience is improved.
The embodiment provides an exposure control method which is applied to terminal equipment. When a camera of the terminal equipment is started, acquiring the current ambient light frequency; judging whether the terminal equipment is in a standard environment or not according to the current environment light frequency; if the terminal equipment is in a non-standard environment, determining a target exposure parameter according to the current ambient light frequency; controlling the camera to expose based on the determined target exposure parameter; therefore, by judging whether the terminal equipment is in the standard environment or not, when the terminal equipment is in the non-standard environment, the target exposure parameter is determined according to the current ambient light frequency, namely, the target exposure parameter is determined according to the current ambient light frequency only aiming at the non-standard environment, and the target exposure parameter is not determined according to the current ambient light frequency aiming at the standard environment, so that misoperation in the standard environment caused by the measurement error of the current ambient light frequency can be effectively avoided; and for the non-standard environment, different environmental light frequencies adopt different exposure parameters, so that the phenomenon of flicker caused by mismatching of the exposure parameters and the current environment due to single exposure parameters can be effectively prevented, and the shooting effect of the image is improved.
In another embodiment of the present application, referring to fig. 3, a flowchart of another exposure control method provided in the embodiment of the present application is shown. As shown in fig. 3, after step S202, when the terminal device is in a standard environment, the method may further include:
s301: judging whether the current ambient light frequency is in a frequency range of a first standard frequency;
it should be noted that the preset frequency range represents a preset frequency range conforming to a standard environment. The standard environment comprises two standard frequencies, namely a first standard frequency and a second standard frequency; thus, the frequency range of the first standard frequency represents a frequency range configured by an environment which is preset to conform to the first standard frequency; the frequency range of the second standard frequency represents a frequency range configured by a preset environment conforming to the second standard frequency, that is, the frequency in the frequency range of the first standard frequency is closer to the first standard frequency, and the frequency in the frequency range of the second standard frequency is closer to the second standard frequency.
In the embodiment of the present application, the first standard frequency may be 50Hz, and the second standard frequency may be 60 Hz; thus, the frequency in the frequency range of the first standard frequency is closer to 50Hz, and the frequency in the frequency range of the second standard frequency is closer to 60 Hz.
It should be noted that, since the preset frequency range includes the frequency range of the first standard frequency and the frequency range of the second standard frequency, that is, within the preset frequency range, the frequency outside the frequency range of the first standard frequency can be regarded as the frequency range of the second standard frequency. For example, assuming that the preset frequency range may be set to 50Hz to 60Hz, since 50Hz to 55Hz is closer to 50Hz, the frequency range of the first standard frequency may be 50Hz to 55Hz, and 56Hz to 60Hz outside the frequency range of the first standard frequency is closer to 60Hz, i.e., the frequency range of the second standard frequency may be 56Hz to 60 Hz; assuming that the preset frequency range may be set to 40Hz to 70Hz, since 40Hz to 55Hz is closer to 50Hz, the frequency range of the first standard frequency may be 40Hz to 55Hz, and 56Hz to 70Hz outside the frequency range of the first standard frequency is closer to 60Hz, i.e., the frequency range of the second standard frequency may be 56Hz to 70 Hz.
S302: if the current ambient light frequency is within the frequency range of a first standard frequency, acquiring a first exposure parameter configured by the first standard frequency, and controlling the camera to be exposed according to the first exposure parameter;
it should be noted that, according to the acquired current ambient light frequency, if it is determined that the current ambient light frequency is within the frequency range of the first standard frequency, it indicates that the current ambient light frequency is closer to the first standard frequency (for example, 50Hz), at this time, a first exposure parameter corresponding to 50Hz may be determined, and then, the camera exposure is controlled according to the first exposure parameter.
Exemplarily, assuming that the preset frequency range may be set to be 50Hz to 60Hz, and the frequency range of the first standard frequency may be 50Hz to 55Hz, if the current ambient light frequency is 53Hz, it may be determined that the current ambient light frequency is within the frequency range of the first standard frequency, which indicates that the current ambient light frequency is closer to 50Hz, and at this time, the camera exposure may be controlled according to the first exposure parameter; the exposure parameters are matched with the current standard environment, so that the flicker phenomenon can be prevented, an image with a good effect is shot, and the user experience is improved.
S303: and if the current ambient light frequency is out of the frequency range of the first standard frequency, acquiring a second exposure parameter configured by a second standard frequency, and controlling the camera to be exposed according to the second exposure parameter.
It should be noted that, according to the acquired current ambient light frequency, if it is determined that the current ambient light frequency is outside the frequency range of the first standard frequency, that is, the current ambient light frequency is within the frequency range of the second standard frequency, it indicates that the current ambient light frequency is closer to the second standard frequency (for example, 60Hz), at this time, a second exposure parameter corresponding to 60Hz may be determined, and then the camera exposure is controlled according to the first exposure parameter.
Exemplarily, it is assumed that the preset frequency range may be set to 50Hz to 60Hz, the frequency range of the first standard frequency may be 50Hz to 55Hz, and the frequency range outside the frequency range of the first standard frequency is 56Hz to 60Hz, i.e., the frequency range of the second standard frequency is 56Hz to 60 Hz; if the current ambient light frequency is 58Hz, determining that the current ambient light frequency is out of the frequency range of the first standard frequency (namely, in the frequency range of the second standard frequency), which indicates that the current ambient light frequency is closer to 60Hz, and controlling the camera to be exposed according to the second exposure parameter; the exposure parameters are matched with the current standard environment, so that the flicker phenomenon can be prevented, an image with a good effect is shot, and the user experience is improved.
The embodiment provides an exposure control method which is applied to terminal equipment. The specific implementation of the foregoing embodiment is elaborated in detail through the foregoing embodiment, and it can be seen that, by determining whether the terminal device is in the standard environment, when the terminal device is in the standard environment, it needs to determine again whether the current ambient light frequency is within the frequency range of the first standard frequency; if the current ambient light frequency is within the frequency range of the first standard frequency, acquiring a first exposure parameter configured by the first standard frequency, and controlling the camera to be exposed according to the first exposure parameter; if the current ambient light frequency is out of the frequency range of the first standard frequency, acquiring a second exposure parameter configured by a second standard frequency, and controlling the camera to be exposed according to the second exposure parameter; therefore, misoperation in a standard environment can be effectively avoided; when the terminal equipment is in a non-standard environment, the target exposure parameters are determined according to the current ambient light frequency, different ambient light frequencies adopt different exposure parameters, the phenomenon of flicker caused by mismatching of the exposure parameters and the current environment due to single exposure parameters can be effectively prevented, and the image shooting effect is improved.
In another embodiment of the present application, referring to fig. 4, a detailed flowchart of an exposure control method provided in an embodiment of the present application is shown. As shown in fig. 4, the terminal device takes a camera as an example, and the detailed process may include:
s401: starting a camera;
s402: acquiring the current ambient light frequency through continuous acquisition of a color temperature sensor;
it should be noted that the camera includes a camera. After the camera receives the starting instruction, a camera in the camera is started, and current ambient light is continuously collected through the color temperature sensor so as to obtain the current ambient light frequency.
S403: judging whether the camera is in a standard environment or not according to the current environment light frequency;
after obtaining the current ambient light frequency, it may be determined whether the camera is in the standard environment according to the current ambient light frequency. The standard environment may refer to an ambient light frequency within a frequency range of 50Hz to 60Hz, or may refer to an ambient light frequency within a wider frequency range, for example, a frequency range of 40Hz to 70Hz, but the embodiment of the present application is not limited specifically.
Specifically, after the ambient light frequency is acquired, the current ambient light frequency may be compared with a preset frequency range, and if the current ambient light frequency is within the preset frequency range, it may be determined that the camera is currently in a standard environment; if the current ambient light frequency is outside the preset frequency range, it can be said that the camera is currently in a non-standard environment. For example, assuming that the preset frequency range is 40Hz to 70Hz, if the current ambient light frequency is 55Hz, the current environment of the camera is a standard environment because 55Hz is within the preset frequency range; if the current ambient light frequency is 35Hz, the fact that 35Hz is out of the preset frequency range indicates that the current environment of the camera is a non-standard environment.
S404: if the camera is in the standard environment, judging whether the camera is in the first standard environment;
s405: if the camera is in the first standard environment, acquiring a first exposure parameter configured by the first standard frequency, and then executing step S407;
s406: if the camera is in a non-first standard environment, acquiring a first exposure parameter configured by a second standard frequency, and then executing step S408;
s407: carrying out exposure control according to the first exposure parameter;
s408: carrying out exposure control according to the second exposure parameter;
it should be noted that, because the standard environment includes two standard frequencies, which are the first standard frequency and the second standard frequency respectively; as such, an environment corresponding to the first standard frequency may be referred to as a first standard environment, and an environment corresponding to the second standard frequency may be referred to as a second standard environment. In addition, the frequency range of the first standard frequency represents a preset frequency range configured according to the first standard environment; the frequency range of the second standard frequency represents a preset frequency range configured to conform to the second standard environment, that is, the frequency in the frequency range of the first standard frequency is closer to the first standard frequency, and the frequency in the frequency range of the second standard frequency is closer to the second standard frequency.
In the embodiment of the present application, the first standard frequency may be 50Hz, and the second standard frequency may be 60 Hz; thus, the frequency in the frequency range of the first standard frequency is closer to 50Hz, and the frequency in the frequency range of the second standard frequency is closer to 60 Hz.
Specifically, when it is determined that the camera is in the standard environment, the current ambient light frequency may be compared with the frequency range of the first standard frequency again to determine whether the camera is in the first standard environment. For example, assuming that the preset frequency range may be set to 50Hz to 60Hz, since 50Hz to 55Hz is closer to 50Hz, the frequency range of the first standard frequency may be 50Hz to 55Hz, and 56Hz to 60Hz outside the frequency range of the first standard frequency is closer to 60Hz, i.e., the frequency range of the second standard frequency may be 56Hz to 60 Hz; if the current ambient light frequency is 53Hz, since 53Hz is in the frequency range of the first standard frequency, it indicates that the current environment of the camera is the first standard environment, at this time, steps S405 and S407 are executed, a first exposure parameter configured by the first standard frequency (for example, 50Hz) is obtained, and exposure control is performed according to the first exposure parameter; if the current ambient light frequency is 58Hz, since 58Hz is outside the frequency range of the first standard frequency (i.e. within the frequency range of the second standard frequency), it indicates that the current environment of the camera is the second standard environment, and at this time, steps S406 and S408 are executed to obtain a second exposure parameter configured by the second standard frequency (e.g. 60Hz), and perform exposure control according to the second exposure parameter.
S409: if the camera is in the non-standard environment, acquiring a target exposure parameter corresponding to the current ambient light frequency, and then executing step S410;
s410: and carrying out exposure control according to the target exposure parameters.
It should be noted that, after the current ambient light frequency is obtained, when the camera is determined to be in the non-standard environment according to the current ambient light frequency, at this time, the exposure parameter corresponding to the current ambient light frequency may be queried according to a pre-stored mapping relationship between the ambient light frequency and the exposure parameter, the queried exposure parameter is determined as the target exposure parameter, and exposure control is performed according to the target exposure parameter.
In the embodiment of the application, whether the color temperature sensor is in the standard environment or not is judged by setting the preset frequency range according to the ambient light frequency acquired by the color temperature sensor, on one hand, when the color temperature sensor is in the standard environment, exposure parameters configured for 50Hz and 60Hz power supply frequencies can be flexibly selected according to the current ambient light frequency to prevent the flicker phenomenon, and misoperation in the standard environment is avoided; on the other hand, when the device is in a non-standard environment, namely under a special environment (under an environment light condition with a power supply frequency of other than 50Hz and 60Hz, for example, the power supply frequency on an airplane is 400Hz) for a user, different exposure parameters are adopted at different ambient light frequencies, so that the phenomenon of flicker caused by mismatching of the exposure parameters and the current environment due to a single exposure parameter can be effectively prevented; meanwhile, because the exposure setting is not directly carried out by utilizing the ambient light frequency acquired by the color temperature sensor, but only when the acquired ambient light frequency is greatly different from the power supply frequencies of 50Hz and 60Hz, the misoperation in the standard environment caused by the error of the color temperature sensor can be effectively avoided.
Through the foregoing embodiments, specific implementations of the foregoing embodiments are explained in detail, and it can be seen that, according to the technical solution of the foregoing embodiments, by determining whether the terminal device is in a standard environment, when the terminal device is in a non-standard environment, the target exposure parameter is determined according to the current ambient light frequency, that is, the application determines the target exposure parameter according to the current ambient light frequency only in the non-standard environment, so that an incorrect operation in the standard environment can be effectively avoided; and for the non-standard environment, different environmental light frequencies adopt different exposure parameters, so that the phenomenon of flicker caused by mismatching of the exposure parameters and the current environment due to single exposure parameters can be effectively prevented, and the shooting effect of the image is improved.
In yet another embodiment of the present application, based on the same inventive concept as the previous embodiment, referring to fig. 5, a composition structure example of an exposure control device 50 provided in the embodiment of the present application is shown. As shown in fig. 5, the exposure control device 50 may include: an acquisition unit 501, a judgment unit 502, a determination unit 503, and a control unit 504, wherein,
