All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be implemented in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The shooting method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a shooting method provided in an embodiment of the present application, where the method may include the following steps:
In this step, the first image may be directly obtained according to the current working mode of the camera, or according to a default working mode, or the working mode of the camera may be adjusted according to the brightness of the ambient light. And under the condition that the brightness of the ambient light is dark, for example, the brightness of the ambient light is less than or equal to a fourth preset threshold, acquiring third image data by adopting a pixel merging mode, and obtaining a first image according to the acquired third image data.
Fig. 2 is a schematic diagram of a pixel merging mode according to an embodiment of the present disclosure. As shown in fig. 2, four adjacent R pixels on the left of the dotted line in fig. 2 are combined into 1R pixel on the right of the dotted line, four adjacent G pixels on the left of the dotted line in fig. 2 are combined into 1G pixel on the right of the dotted line, and four adjacent B pixels on the left of the dotted line in fig. 2 are combined into 1B pixel on the right of the dotted line, so that the image resolution is reduced, and the brightness of the pixels is improved. Wherein, R represents red, G represents green, B represents blue, and RGB is a color representing three channels of red, green, and blue. In addition to the embodiment shown in fig. 2, other numbers of pixel combination modes may be adopted, such as nine-in-one pixel combination, sixteen-in-one pixel combination, and the like, which is not specifically limited in this embodiment of the present invention.
And acquiring third image data by adopting a pixel merging mode under the condition that the brightness of the ambient light is less than or equal to a fourth preset threshold value, so that the brightness of the whole picture of the preview image can be improved under the condition that the brightness of the ambient light is dark.
It should be noted that, when the brightness of the ambient light is greater than or equal to the third preset threshold, the image data is acquired in the single-pixel mode, and the first image is obtained according to the acquired image data.
Under the condition that the brightness of the ambient light is greater than or equal to the third preset threshold value, the single-pixel mode is adopted to collect image data, so that under the condition that the ambient light is bright, the definition of the whole picture of the previewed image can be ensured through the single-pixel mode. The single pixel mode is a Full Size mode, refer to fig. 3, and fig. 3 is a schematic diagram of the single pixel mode provided in the embodiment of the present application, the single pixel mode rearranges pixel points output by the imaging sensor into normal pixel points, the resolution of an image is unchanged, the definition of the image in this mode is high, a process of rearranging the pixel points is called bayer image regeneration, namely remosaic, and the rearranged pixel points are shown on the right of a dotted line in fig. 3.
In this step, an overexposed area or a darker area in the first image may be determined as a target image area, so that image acquisition is performed again in a targeted manner to achieve a better image effect.
Wherein, determining the target image area in the first image can be realized by the following steps:
determining a region of which the brightness value is less than or equal to a first preset threshold value in the first image as a target image region; the first working mode is a pixel merging mode;
or determining a region of the first image with the brightness value being greater than or equal to a second preset threshold value as a target image region; the first operation mode is a single pixel mode.
In this way, the image can be reacquired in a binning mode for darker areas or in a single pixel mode for overexposed areas, thereby preventing the image from being darker or overexposed.
It should be noted that, if the first image is obtained according to the third image data acquired by using the pixel combination mode, since the pixel combination mode may increase the brightness of the pixel point, an overexposed region may exist in the first image, and the overexposed region is determined as the target image region. In this embodiment, a region in the first image with a luminance value greater than or equal to the second preset threshold may be determined as the target image region, that is, the region in the first image with a luminance value greater than or equal to the second preset threshold is considered as the overexposure region.
If the first image is obtained according to the third image data acquired in the single-pixel mode, the brightness of the pixel points cannot be improved in the single-pixel mode, but the definition of the first image can be guaranteed, so that a relatively dark area may exist in the first image, and the relatively dark area is determined as a target image area. In this embodiment, a region of the first image with a luminance value less than or equal to the first preset threshold may be determined as the target image region, that is, the region of the first image with a luminance value less than or equal to the first preset threshold is considered as a relatively dark region.
Optionally, determining the target image area in the first image may also be implemented by:
receiving a first input of a user to a first image;
in response to the first input, a region in the first image selected by the user is determined as the target image region.
As shown in fig. 4, fig. 4 is a schematic view of a shooting interface provided in an embodiment of the present application. The user may circle the region 401 desired to acquire the HDR effect in the first image displayed on the screen, that is, the first input may be an operation of the user to circle the region 401 desired to acquire the HDR effect, and the electronic device takes an image of the region desired to acquire the HDR effect, which is circled by the user, as the target region image in response to the first input.
After the target image area is determined, a target photosensitive area corresponding to the target image area may be determined. The target photosensitive area refers to an area where a photosensitive element in the camera is located.
Optionally, when the first image is obtained according to third image data acquired in the pixel merging mode, and a region in the first image, where a luminance value is greater than or equal to a second preset threshold, is determined as a target image region, the first operating mode is a single-pixel mode, that is, the first image data is acquired through the target photosensitive region in the single-pixel mode.
Optionally, when the first image is obtained according to third image data acquired in a single-pixel mode, and a region in the first image, where a luminance value is smaller than or equal to a first preset threshold, is determined as a target image region, the first operating mode is a pixel merging mode, that is, the first image data is acquired through the target photosensitive region in the pixel merging mode.
104, obtaining a target image according to the first image data and the second image data; the second image data is acquired by adopting a second working mode, and the first working mode is different from the second working mode.
It should be noted that the second image data may be data acquired through other photosensitive areas in the second operating mode, where the other photosensitive areas refer to areas other than the target photosensitive area in the camera. In the application, different working modes can be simultaneously adopted to acquire image data of different areas, namely, a first working mode can be simultaneously adopted to acquire first image data through a target photosensitive area, a second working mode is adopted to acquire second image data through other photosensitive areas, and then a target image is obtained according to the first image data and the second image data.
For example, referring to fig. 5 and fig. 6, fig. 5 is a schematic diagram of a first image provided in an embodiment of the present application, and fig. 6 is a schematic diagram of obtaining a target image by using different operation modes provided in an embodiment of the present application. The region of the first image with the luminance value less than or equal to the first preset threshold is, for example, a solid-line frame region 501 shown in fig. 5, in which case the solid-line frame region 501 is a target photosensitive region, and the other photosensitive regions are, for example, a dashed-line frame region 502 shown in fig. 5. As shown in fig. 6 according to the result identified in fig. 5, the first operating mode is a pixel merge mode, and the second operating mode is a single-pixel mode, that is, the pixel merge mode is used to collect the first image data through the target photosensitive area, so as to improve the brightness of the image obtained according to the image data collected by the target photosensitive area.
The second image data and the first image data may not be acquired at the same time, that is, the second image data and the first image data are data of different frame images, and the target image may be obtained by performing synthesis calculation on the data of the different frame images.
For example, as shown in fig. 7, fig. 7 is a schematic diagram for obtaining a target image according to an embodiment of the present application, and the schematic diagram on the left of the ellipses in fig. 7 represents a first image acquired when the brightness of the ambient light is equal to or less than a fourth preset threshold. When the brightness of the ambient light is smaller than or equal to a fourth preset threshold value, the first image is obtained according to third image data acquired by adopting a pixel merging mode, and an area with the brightness value larger than or equal to a second preset threshold value in the first image is determined as a target image area, and the first working mode is a single pixel mode, the second working mode is the pixel merging mode, and the first image data is acquired through a target photosensitive area by adopting the single pixel mode.
Specifically, the second image data may be third image data acquired by using the pixel merge mode when the first image is acquired, that is, the second image data may be data of an nth frame image shown in fig. 7. After the second image data is obtained, the first image data can be collected through the target photosensitive area again in the single-pixel mode, and the first image data and the second image data are data of different frame images. And then, obtaining a target image according to the first image data and the second image data, wherein the exposure value is not required to be changed in the whole process of obtaining the target image, and the obtained first image data and the second image data are image data collected under the same exposure value, so that data which do not belong to the same area as the first image data in the second image data are not required to participate in synthesis calculation, and the synthesis calculation amount is small compared with the synthesis calculation amount of synthesizing a whole frame of image under different exposure values of a plurality of frames in the prior art. Only data in the second image data, which belong to the same region as the first image data, needs to be synthesized with the first image data to obtain a target image. When the brightness of the ambient light is less than or equal to the fourth preset threshold, the pixel merging mode is adopted to collect the third image data, so that the brightness of the first image obtained according to the third image data can be improved, the dark area can be brightened, meanwhile, in order to avoid overexposure, the single pixel mode is adopted to collect the first image data through the target photosensitive area, so that the overexposure of the image collected by the target photosensitive area can be avoided, and the obtained target image is an image with a high dynamic range effect. Therefore, by reducing the amount of synthesis calculation, the efficiency of obtaining an image of the HDR effect is improved.
Optionally, when the brightness of the ambient light is greater than or equal to a third preset threshold, the first image is obtained according to third image data acquired in a single-pixel mode, and a region in the first image, where the brightness value is less than or equal to the first preset threshold, is determined as a target image region, the first working mode is a pixel merge mode, the second working mode is a single-pixel mode, the first image data is acquired through the target photosensitive region in the pixel merge mode, and the second image data is acquired in the single-pixel mode.
Specifically, the second image data may be third image data acquired in a single-pixel mode when the first image is acquired. And then obtaining the target image according to the first image data and the second image data, wherein the obtained target image also reduces the synthesis calculation amount. When the brightness of the ambient light is greater than or equal to a third preset threshold value, the single-pixel mode is adopted to collect the third image data, so that the definition of a first image obtained according to the third image data can be ensured, meanwhile, in order to avoid the problem of a dark area in the first image, the pixel merging mode is adopted to collect the first image data through the target photosensitive area, so that the problem of dark brightness of an image corresponding to the first image data collected by the target photosensitive area can be avoided, and the obtained target image is an image with a high dynamic range effect. Therefore, by reducing the amount of synthesis calculation, the efficiency of obtaining an image of the HDR effect is improved.
Optionally, the third preset threshold is used to determine whether overexposure is performed, and the fourth preset threshold is used to determine whether darkness is performed, so that the third preset threshold may be set to be greater than the fourth preset threshold.
In the shooting method provided by the embodiment, a first image is acquired through a camera, a target image area in the first image is determined, a target photosensitive area corresponding to the target image area is determined, first image data is acquired through the target photosensitive area by adopting a first working mode, and a target image is acquired according to the first image data and second image data; the second image data is acquired by adopting a second working mode, and the first working mode is different from the second working mode, so that the calculated amount is reduced, and the efficiency of acquiring the image with the HDR effect is improved.
