Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a photographic exposure method according to an exemplary embodiment. As shown in fig. 1, the method is used in a photographing apparatus (e.g., a camera, a mobile phone with a photographing function, etc.). The shooting exposure method according to the embodiment of the disclosure includes:
in step S11, acquiring the brightness characteristics of the current shooting environment according to the detection mode;
in step S12, an exposure mode is determined based on the luminance characteristics;
in step S13, a captured exposure value corresponding to the exposure mode is acquired;
in step S14, a photographic exposure is performed at the photographic exposure value.
According to the embodiment of the disclosure, the brightness characteristic of the current shooting environment is obtained through the detection mode, the exposure mode is determined based on the brightness characteristic, the shooting exposure value corresponding to the exposure mode is obtained, shooting exposure is carried out according to the shooting exposure value, the exposure mode corresponding to the brightness characteristic is automatically determined under the brightness characteristics of different shooting environments, the corresponding shooting exposure value is obtained, and therefore the shooting exposure effect is improved.
For example, when the user opens the shooting device to shoot, the shooting device may obtain the brightness feature of the current shooting environment according to the detection mode.
Fig. 2 is a flowchart illustrating a photographic exposure method according to an exemplary embodiment. In one possible implementation, as shown in fig. 2, step S11 may include:
in step S111, the luminance characteristics of the current shooting environment are acquired by the light sensor.
For example, the brightness characteristic of the current shooting environment may be obtained by a detection manner of a light sensor (light sensor), where the light sensor may be used to sense the intensity of light and feed back the light to a shooting device (e.g., a mobile phone with a shooting function) provided with the light sensor, so as to obtain the brightness characteristic of the current shooting environment and feed back the brightness characteristic to the shooting device.
In step S112, the luminance characteristics of the current shooting environment are acquired by the camera sensor.
For example, the brightness characteristic of the current shooting environment may be obtained by a detection manner of a camera sensor (camera sensor), where the camera sensor may be configured to receive light passing through the camera and convert the light signal into an electrical signal, so as to obtain the brightness characteristic of the current shooting environment, and feed the brightness characteristic back to a shooting device (e.g., a mobile phone with a shooting function) provided with the light sensor. For example, when shooting is performed by a mobile phone having a shooting function, the ambient brightness can be detected by a camera sensor disposed in front of the mobile phone.
In this way, the brightness characteristics of the current shooting environment can be accurately acquired. It should be understood by those skilled in the art that the brightness characteristic of the current shooting environment may be obtained by the light sensor or the camera sensor, or may be obtained by both the light sensor and the camera sensor, as long as the brightness characteristic of the current shooting environment can be obtained, which is not limited by the present disclosure.
Fig. 3 is a flowchart illustrating a photographic exposure method according to an exemplary embodiment. In one possible implementation, as shown in fig. 3, step S12 may include:
in step S121, in the case where the luminance characteristic is less than or equal to the first luminance threshold value, it is determined that the exposure mode is the long exposure mode,
wherein the long exposure mode comprises single long exposure or multiple long exposures.
For example, when it is acquired that the brightness feature of the current shooting environment is less than or equal to the first brightness threshold (the shooting environment is dark), the exposure mode may be determined to be a long exposure mode, where the long exposure mode may include a single long exposure or multiple long exposures. Thus, the object to be photographed can be recognized more accurately. It will be understood by those skilled in the art that the first brightness threshold may be set as desired, and the present disclosure is not limited thereto.
In one possible implementation, the long exposure mode may be a single long exposure. For example, a long exposure may be performed, the exposure time being extended to the first time, thereby accurately identifying the object to be photographed. It will be understood by those skilled in the art that the length of the first time may be set as needed as long as the object to be photographed can be accurately identified, and the present disclosure does not limit this.
In one possible implementation, in a case where the long Exposure mode is a single long Exposure, an Exposure Value (EV) of the single long Exposure is a shot Exposure Value corresponding to the single long Exposure mode, where the shot Exposure Value is an Exposure Value used to shoot the Exposure. It will be understood by those skilled in the art that the shot exposure value corresponding to a single long exposure may be acquired by a related art, and the present disclosure is not limited thereto.
In one possible implementation, the long exposure mode may be a multiple long exposure. For example, a long exposure greater than one time may be performed. For example, the length of each exposure time may be the second time (multiple long exposures with the same exposure time), but the exposure value changes, and the threshold value of the variation range interval may be: the first exposure value at which the object to be photographed can be identified and the last exposure value at which the object to be photographed can be identified, in this case, a plurality of long exposures may be performed within the variation range section (the number of exposures may be determined by the variation range section). It will be understood by those skilled in the art that the length of the second time can be set as desired, and the present disclosure is not limited thereto.
Fig. 4 is a flowchart illustrating a photographic exposure method according to an exemplary embodiment. In one possible implementation, as shown in fig. 4, step S13 may include:
in step S131, in the case where the long exposure manner is a multiple long exposure, an exposure value of the multiple long exposure between the minimum exposure value and the maximum exposure value at which the object to be photographed is identified is acquired.
For example, when the determined exposure mode is a long exposure mode and is a multiple long exposure, an exposure value of the multiple long exposure between the minimum exposure value and the maximum exposure value at which the object to be photographed can be identified may be acquired. For example, when a dark skin color face is photographed in a dark environment, a plurality of long exposures may be performed. Meanwhile, the exposure value of multiple long exposures between the minimum exposure value and the maximum exposure value of the face with the dark skin color can be acquired, wherein the exposure times can be determined according to the minimum exposure value and the maximum exposure.
It will be understood by those skilled in the art that the exposure value of the multiple long exposures between the minimum exposure value and the maximum exposure value of the object to be photographed can be obtained by the related art, and the exposure value changing manner can be sequentially long-exposed from the absolute value minimum to the absolute value maximum, and can also be sequentially long-exposed from the absolute value maximum to the absolute value minimum, which is not limited by the present disclosure.
In step S132, a photographic exposure value corresponding to the long exposure mode is determined based on the exposure value of the plurality of long exposures.
For example, a shot exposure value corresponding to a multiple long exposure manner may be determined from an exposure value of a multiple long exposure, wherein the shot exposure value is an exposure value used for shooting.
In one possible implementation, the photographing exposure value may be determined based on a minimum exposure value and a maximum exposure value at which the object to be photographed is identified. For example, when the minimum exposure value of the object to be photographed is identified as X, and the maximum exposure value of the object to be photographed is identified as Y, the following formula may be used: l (X + Y)/2| to determine a shot exposure value corresponding to the multiple long exposure mode.
In this way, a shot exposure value corresponding to the multiple long exposure mode can be acquired. It will be understood by those skilled in the art that the shot exposure value corresponding to the multiple long exposure mode can be determined in various ways known in the art, and the present disclosure is not limited thereto.
Fig. 5 is a flowchart illustrating a photographic exposure method according to an exemplary embodiment. In one possible implementation manner, as shown in fig. 5, step S12 may further include:
in step S122, in the case where the brightness feature is greater than or equal to the second brightness threshold, it is determined that the exposure mode is the short exposure mode,
wherein, the short exposure mode comprises single short exposure or multiple short exposures.
For example, when it is acquired that the brightness characteristic of the current shooting environment is greater than or equal to the second brightness threshold (the shooting environment is brighter), it may be determined that the exposure mode is a short exposure mode, where the short exposure mode may include a single short exposure or multiple short exposures. Thus, the object to be photographed can be recognized more accurately. It will be understood by those skilled in the art that the second brightness threshold may be set as desired, and the present disclosure is not limited thereto.
In one possible implementation, the short exposure mode may be a single short exposure. For example, a short exposure may be performed once, and the exposure time is shortened to a third time, thereby accurately identifying the object to be photographed. It will be understood by those skilled in the art that the length of the third time can be set as desired, and the present disclosure is not limited thereto.
In one possible implementation, in the case that the short exposure mode is a single short exposure, the exposure value of the single short exposure is a shot exposure value corresponding to the single short exposure mode, wherein the shot exposure value is an exposure value used for shooting. It will be understood by those skilled in the art that the shot exposure value corresponding to a single short exposure can be acquired by the related art, and the present disclosure is not limited thereto.
In one possible implementation, the short exposure mode may be multiple short exposures. For example, a short exposure greater than one time may be performed. For example, the length of each exposure time may be the fourth time (the same time for each exposure time for multiple short exposures), but the exposure value may be changed, and the threshold value of the variation range interval may be: the first exposure value at which the object to be photographed can be identified and the last exposure value at which the object to be photographed can be identified, in this case, a plurality of short exposures may be performed within the variation range section (the number of exposures may be determined by the variation range section). Those skilled in the art will appreciate that the length of the fourth time can be set as desired, and the present disclosure is not limited thereto.
Fig. 6 is a flowchart illustrating a photographic exposure method according to an exemplary embodiment. In one possible implementation, as shown in fig. 6, step S13 may include:
in step S133, in the case where the short exposure manner is multiple short exposures, an exposure value of the multiple short exposures between the minimum exposure value and the maximum exposure value at which the object to be photographed is identified is acquired.
For example, when the determined exposure mode is a short exposure mode and is a multiple short exposure mode, an exposure value of the multiple short exposure between the minimum exposure value and the maximum exposure value at which the object to be photographed can be identified may be acquired. For example, when a human face with a light skin color is photographed in a bright environment, short exposure may be performed a plurality of times. Meanwhile, the exposure value of multiple short exposures between the minimum exposure value and the maximum exposure value of the face with the light skin color can be acquired, wherein the exposure times can be determined according to the minimum exposure value and the maximum exposure.
It will be understood by those skilled in the art that the exposure value of the multiple short exposures between the minimum exposure value and the maximum exposure value of the object to be photographed can be obtained by the related art, and the exposure value change manner may be sequentially short-exposed from the absolute value minimum to the absolute value maximum, or sequentially short-exposed from the absolute value maximum to the absolute value minimum, which is not limited by the present disclosure.
In step S134, a shot exposure value corresponding to the short exposure mode is determined based on the exposure values of the plurality of short exposures.
For example, a shot exposure value corresponding to a multiple short exposure manner may be determined from an exposure value of the multiple short exposures, where the shot exposure value is an exposure value used for shooting.
In one possible implementation, the photographing exposure value may be determined based on a minimum exposure value and a maximum exposure value at which the object to be photographed is identified. For example, when the minimum exposure value of the object to be photographed is identified as M, and the maximum exposure value of the object to be photographed is identified as N, the following formula may be used: l (M + N)/2| to determine a shot exposure value corresponding to the multiple short exposure mode.
In this way, a shot exposure value corresponding to the multiple short exposure mode can be acquired. It will be understood by those skilled in the art that the shot exposure value corresponding to the multiple short exposure mode can be determined in various ways known in the art, and the present disclosure is not limited thereto.
Application example
An application example according to the embodiment of the present disclosure is given below in conjunction with "a user takes a picture through a mobile phone" as an exemplary application scenario to facilitate understanding of a flow of a shooting exposure method. It should be understood by those skilled in the art that the following application examples are only for the purpose of facilitating understanding of the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.
Fig. 7 is a schematic diagram illustrating an application scenario of a photographic exposure method according to an exemplary embodiment. As shown in fig. 7, in this application example, the user takes a photograph through a cell phone.
In this application example, a user may issue a photo taking request to a mobile phone with a photo taking function, and the mobile phone starts a camera after responding to the photo taking request (step 701).
In this application example, the mobile phone may obtain the brightness characteristic of the current shooting environment through the light sensor or the front camera sensor of the mobile phone, and also through the light sensor and the front camera sensor of the mobile phone at the same time (step 702).
In this application example, when the luminance characteristic of the current shooting environment is acquired to be less than or equal to the first luminance threshold (for example, a darker luminance characteristic), the exposure mode is determined to be a long exposure mode (step 703), for example, a multiple long exposure mode. In this application example, exposure values for multiple long exposures between a minimum exposure value and a maximum exposure value identifying an object to be photographed (e.g., a dark skin face) may be obtained (step 704). For example, an exposure value of a plurality of long exposures between the minimum exposure value P and the maximum exposure value Q may be acquired, wherein the number of exposures is determined by the range of the minimum exposure value P and the maximum exposure value Q.
In this application example, a shot exposure value corresponding to the multiple long exposure manner may be determined based on the acquired exposure value of the multiple long exposure, wherein the shot exposure value is an exposure value used to shoot exposure. In this application example, the photographing exposure value may be determined according to the formula | (P + Q)/2| (step 705).
In this application example, a shot exposure may be performed on a subject to be shot (e.g., a dark skin-colored human face) with the obtained shot exposure value (step 708).
In this application example, when it is acquired that the brightness feature of the current shooting environment is greater than or equal to the second brightness threshold (e.g., a brighter brightness feature), it is determined that the exposure mode is the short exposure mode (step 706), for example, the single short exposure mode. In this application example, a single short exposure may be performed, and the exposure time is shortened to a fourth time (which may be set as the case may be). In this application example, a shooting exposure value corresponding to a single short exposure is acquired, for example, an exposure value at which an object to be shot (a face of a light skin color) can be recognized is acquired as a shooting exposure value corresponding to a single short exposure (step 707).
In this application example, a photographic exposure may be performed on an object to be photographed (e.g., a human face with a light skin color) with the acquired photographic exposure value (step 708).
According to the embodiment of the disclosure, the brightness characteristic of the current shooting environment is obtained through the detection mode, the exposure mode is determined based on the brightness characteristic, the shooting exposure value corresponding to the exposure mode is obtained, and shooting exposure is carried out by the shooting exposure value, so that the exposure mode corresponding to the brightness characteristic is automatically determined under the brightness characteristics of different shooting environments, the corresponding shooting exposure value is obtained, and the shooting effect is improved.
