In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
Fig. 1 is a flowchart of an image capturing method provided by an embodiment of the present disclosure, which may be performed by an image capturing apparatus. As shown in fig. 1, the image capturing method provided in this embodiment includes the following steps:
and S101, acquiring the sensitivity of the photosensitive element in the current environment.
The photosensitive element in the embodiments of the present disclosure may be understood as an electronic element capable of converting light entering a lens into an analog electrical signal, and is a core component of a camera, a mobile phone, or other terminal devices with an image capturing function to implement the image capturing function.
The sensitivity in the embodiments of the present disclosure may be understood as a parameter for measuring the sensitivity to light, and in the case where other parameters are not changed, the higher the sensitivity, the higher the sheet luminance, and in the automatic mode, when the ambient luminance is lower, the sensitivity of the photosensitive element is increased, and conversely, the sensitivity is decreased, in order to ensure a sufficient light input amount.
In the embodiment of the disclosure, the image acquisition device can acquire a specific value of the sensitivity of the photosensitive element under the current ambient brightness.
And S102, comparing the sensitivity with a first preset threshold value.
The first preset threshold in the embodiment of the present disclosure may be understood as a preset sensitivity threshold for determining whether the current environment is a dim environment, for example, the first preset threshold may be 2000, and is not limited herein.
In the embodiment of the present disclosure, the image capturing apparatus may compare the obtained sensitivity of the photosensitive element with a first preset threshold.
And S103, in response to the sensitivity being greater than or equal to the first preset threshold, shortening the automatic shutter time corresponding to the sensitivity to a preset shutter time corresponding to the sensitivity.
The shutter time in the embodiments of the present disclosure may be understood as a time when light can enter the photosensitive element, and under the condition that other parameters are not changed, the longer the shutter time is, the higher the brightness of the formed film is, and under the automatic mode, when the ambient brightness is lower, the shutter time may be extended to ensure a sufficient light entering amount, and vice versa.
The automatic shutter time in the embodiment of the present disclosure may be understood as a shutter time corresponding to sensitivity determined by the image capturing apparatus according to the sensitivity in the automatic mode, and the preset shutter time may be understood as a preset shutter time after shortening the automatic shutter time corresponding to the sensitivity, for example, the automatic shutter time may be 1/33 second and the preset shutter time may be 1/66 second when the sensitivity is 2000, which is not limited herein.
In the embodiment of the disclosure, a corresponding relationship exists among the ambient brightness, the light sensitivity of the photosensitive element and the shutter time in the automatic mode, when the ambient brightness is darker, the light sensitivity in the automatic mode is higher, and the shutter time is also longer, so that it is ensured that there is enough light entering amount in a dark scene, and the final filming brightness is higher, but when the ambient brightness is too dark, the shutter time is too long, which may cause the natural vibration of the human body to be captured by the image acquisition device, and further cause the filming blur.
In an embodiment of the disclosure, the image capturing apparatus may shorten an automatic shutter time corresponding to the sensitivity in the automatic mode to a preset shutter time corresponding to the sensitivity when it is determined that the sensitivity of the photosensitive element is greater than or equal to the first preset threshold.
In an exemplary implementation manner of the embodiment of the disclosure, when it is determined that the sensitivity of the photosensitive element is greater than or equal to the first preset threshold, the image capturing device may acquire a corresponding relationship between the sensitivity and the preset shutter time, which is pre-stored in the database, and determine the preset shutter time corresponding to the current sensitivity according to the corresponding relationship, so as to shorten the automatic shutter time to the preset shutter time.
And S104, responding to an image acquisition instruction input by a user, and acquiring the image according to the sensitivity and the preset shutter time.
The image capturing instruction in the embodiment of the present disclosure may be understood as an instruction for performing an image capturing operation, and for example, the image capturing instruction may be a voice instruction, a gesture instruction, a touch instruction, and the like, which is not limited herein.
In the embodiment of the disclosure, the image capturing apparatus may perform an image capturing operation according to the current sensitivity and the preset shutter time after receiving an image capturing instruction input by a user.
According to the embodiment of the disclosure, by acquiring the sensitivity of the photosensitive element in the current environment, comparing the sensitivity with the first preset threshold, and in response to the sensitivity being greater than or equal to the first preset threshold, shortening the automatic shutter time corresponding to the sensitivity to the preset shutter time corresponding to the sensitivity, and in response to an image acquisition instruction input by a user, acquiring an image by using the sensitivity and the preset shutter time, in an automatic mode of the image acquisition equipment in a dark scene, shortening the longer shutter time to the preset shutter time corresponding to the sensitivity, the preset shutter time can avoid the occurrence of a blurring phenomenon caused by shaking of the image acquisition equipment, even in an environment with insufficient light, the user can easily take clear pictures, and the photographing experience of the user is improved.

And S202, responding to the zero times, and comparing the sensitivity with a first preset threshold value.
In this embodiment, the image capturing device may compare the sensitivity of the photosensitive element in the current environment with a first preset threshold when the number of times of receiving the image capturing instruction in the current time period is zero.
And S203, responding to the condition that the number of times is not zero, and when the image acquisition instruction is acquired, acquiring the image by using the sensitivity and the automatic shutter time corresponding to the sensitivity.
In the embodiment of the present disclosure, when the number of times of receiving the image capture instruction in the current time period is not zero, after receiving the image capture instruction input by the user, the image capture device may perform the image capture operation according to the current sensitivity and the unreduced automatic shutter time corresponding to the sensitivity.
The method and the device for acquiring the images in the dark environment have the advantages that the number of times of receiving the image acquisition instruction in the current time period is determined, the light sensitivity is compared with the first preset threshold when the response number is zero, the image acquisition is performed according to the automatic shutter time corresponding to the light sensitivity and the light sensitivity when the response number is not zero when the image acquisition instruction is acquired, whether the user frequently performs image acquisition can be judged according to the number of times of the image acquisition instruction received in the current time period, if the number is zero, the user does not frequently perform image acquisition, the shutter time needs to be shortened to avoid blurring of the images in the dark environment, if the number is not zero, the user frequently takes the images, certain shooting basis is provided, and the stability of the device can be more noticed when the user takes the images in the dark environment, so that the shutter time does not need to be shortened to avoid blurring of the images, different image acquisition strategies can be executed for different users, and the shooting experience of the user is further improved.
Fig. 3 is a flowchart of a method for shortening a shutter time according to an embodiment of the present disclosure, and as shown in fig. 3, on the basis of the above embodiment, the shutter time can be shortened as follows.
And S301, in response to the sensitivity being greater than or equal to the first preset threshold, comparing the sensitivity with a second preset threshold.
The second preset threshold in the embodiment of the present disclosure may be understood as a preset sensitivity threshold for determining the degree of darkness of the current environment, and the second preset threshold is greater than the first preset threshold, for example, when the first preset threshold is 2000, the second preset threshold may be 3000, and is not limited herein. In the automatic mode, the ambient brightness corresponding to the second preset threshold is darker than the ambient brightness corresponding to the first preset threshold, and the automatic shutter time corresponding to the second preset threshold is longer than the automatic shutter time corresponding to the first preset threshold.
In the embodiment of the disclosure, the image capturing apparatus may continue to compare the sensitivity with a second higher preset threshold when the sensitivity of the photosensitive element in the current environment is greater than or equal to the first preset threshold.

The second preset shutter time in the embodiments of the present disclosure may be understood as a preset shutter time corresponding to a sensitivity greater than or equal to a second preset threshold, and the first preset shutter time is greater than the second preset shutter time, for example, when the second preset threshold is 3000, the second preset shutter time may be 1/100 second, and is not limited herein.
In the embodiment of the present disclosure, the image capturing apparatus may shorten an automatic shutter time corresponding to the sensitivity in the automatic mode to a preset second preset shutter time corresponding to the sensitivity when it is determined that the sensitivity of the photosensitive element is greater than or equal to a second preset threshold.
