Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, 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, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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.
Fig. 1 shows a flowchart of a method for capturing an image according to an embodiment of the present application, which may be performed by an electronic device, such as a terminal device. In other words, the method may be performed by software or hardware installed in the terminal device. As shown, the method may include the following steps.
S110: and shooting at least three images with different exposure values according to a preset exposure value adjusting rule.
When a user uses the electronic device to take a picture, the HDR picture taking mode may be adopted for a scene with a large dynamic range. In this step, at least three images with different exposure values can be shot according to the preset exposure value adjustment rule. Optionally, the preset exposure value may be automatically set by an electronic device, or may be manually set by a user, which is not specifically limited in this embodiment of the present invention.
Where the present embodiment is directed to capturing images according to EV adjustment rules set by a user and synthesizing HDR images in subsequent steps based thereon, various EV adjustment rules that can be easily conceived by those skilled in the art can be applied to the present embodiment.
S120: and receiving first selection operation of the user on at least two target images in the at least three images.
In this step, a first selection operation by the user is received to determine a target image from among the plurality of captured images.
S130: responding to the first selection operation, synthesizing the at least two target images and outputting a high dynamic range image; and different target brightness areas in the high dynamic range image respectively correspond to different target images.
For scenes with a large dynamic range, the image may be pre-divided into different target luminance regions: 1. normal sub-region, 2, over-bright sub-region and/or over-dark sub-region. Responding to the first selection operation, synthesizing the at least two target images and outputting a high dynamic range image; and different target brightness areas in the high dynamic range image respectively correspond to different target images. Optionally, the image division may be automatically completed by an electronic device, or may be manually divided by a user, which is not specifically limited in this embodiment of the present invention.
Fig. 2 shows a schematic diagram of an HDR photographic scene, as shown, the image is pre-divided into 3 target luminance regions: the normal sub-region, the over-bright sub-region and the over-dark sub-region are exemplified for explanation. The brighter sun in the preview image can be used as an over-bright subregion, the long-range trees with normal brightness can be used as a normal subregion, and the darker backlit characters can be used as an over-dark subregion and the like.
In one implementation, a first selection operation of a user is received in the last step to determine a target image from among a plurality of captured images. For example, it may be determined that the three target images correspond to an over-bright sub-area, an over-dark sub-area, and a normal sub-area, respectively.
In this step, in response to the first selection operation of the previous step, the target images are synthesized into an HDR image according to the correspondence between different target luminance regions and different target images in the high dynamic range image, and the HDR image is output. In particular, a first target image is used in the too bright sub-area, a second target image is used in the too dark sub-area, and a third target image is used in the normal sub-area, whereby three target images are combined into one high dynamic range HDR image, which outputting the HDR image may include saving or displaying the HDR image.
Therefore, according to the method for shooting the image, at least three images with different exposure values are shot according to the preset exposure value adjusting rule; receiving first selection operation of a user on at least two target images in the at least three images; responding to the first selection operation, synthesizing the at least two target images and outputting a high dynamic range image; different target brightness areas in the high dynamic range image correspond to different target images respectively, a user can flexibly select a target image to be synthesized, and the quality and flexibility of shooting HDR images are improved.
In one possible implementation, before the outputting the high dynamic range image, the method further includes: and determining a target brightness area corresponding to each target image according to the exposure value of each target image, wherein the exposure value of the target image is positively correlated with the average brightness value of the target brightness area corresponding to the target image. Specifically, if the exposure value of the target image is low, the average luminance value of the target luminance region corresponding thereto is low; if the exposure value of the target image is high, the average brightness value of the corresponding target brightness region is high.
Therefore, according to the method for shooting the image, the target brightness area corresponding to each target image can be automatically determined based on the target image selected by the user, and the composite HDR image can be automatically generated.
In a possible implementation manner, after the outputting of the high dynamic range image, a second selection operation of the user on a first image, except for the target image, of the at least three images may be further received; and synthesizing the high dynamic range image and the first image in response to the second selection operation, and outputting a second high dynamic range image.
Alternatively, after receiving the second selection operation, the target image selected by the first selection operation and the target image selected by the second selection operation may be combined and the HDR image may be output, a part of the target image selected by the first selection operation may be retained, and another part of the target image may be discarded, and the retained part of the target image selected by the second selection operation and the target image selected by the first selection operation may be combined and the HDR image may be output, or all the target images selected by the first selection operation may be discarded, and only the target image selected by the second selection operation may be combined and the HDR image may be output.
Therefore, the method for shooting the image, provided by the embodiment of the application, can enable a user to conveniently and quickly adjust or modify the selected target image after the first selection, and further ensure the quality of the synthesized image and the flexibility of operation.
Fig. 3 is a flowchart illustrating a method for capturing an image according to an embodiment of the present disclosure, which may be performed by an electronic device, such as a terminal device. In other words, the method may be performed by software or hardware installed in the terminal device. As shown, the method may include the following steps.
S311: and receiving the maximum EV value, the minimum EV value and the EV value interval set by the user.
Alternatively, a reception shooting mode switching operation may be included before this step. Specifically, when it is not monitored that the user clicks a key of the user-defined HDR, normal shooting is performed. Upon receiving an operation of switching the photographing mode, the following steps are performed.
When a user uses the electronic device to take a picture, the HDR picture taking mode may be adopted for a scene with a large dynamic range. In this step, an EV adjustment rule set by the user may be received.
Fig. 4a shows a schematic diagram of EV adjustment rules set by a receiving user, and as shown in the figure, in one implementation, the step may include: and receiving the maximum EV value, the minimum EV value and the EV value interval set by the user.
In the figure, there are 3 sliders in the preview image, corresponding to the "maximum EV value", the "minimum EV value", and the "EV value interval", respectively. The default range of the maximum EV value is-20 EV- + 20EV, and the user can set the maximum EV value for taking a picture to be +2EV by sliding; similarly, the minimum EV value may be set to-3 EV and the EV value interval may be set to 1 EV.
In one implementation, after the step, it may also be monitored in real time whether the user has triggered an operation to complete the step, for example, clicking a "complete set" button.
Shooting at least three images with different exposure values according to a preset exposure value adjusting rule S312: from the minimum EV value, one image is taken every 1EV value interval until the EV value reaches or exceeds the maximum EV value.
In the example shown in FIG. 4a, the electronic device will take 6 images in the order of-3 EV, -2EV, -1EV, -0EV, +1EV, +2 EV.
It should be noted that the present embodiment is described by taking an image every 1EV value interval from the minimum EV value until the EV value reaches or exceeds the maximum EV value, but the present embodiment is intended to take an image according to the EV adjustment rule set by the user and synthesize an HDR image based on the image, and various EV adjustment rules that can be easily conceived by those skilled in the art can be applied to the present embodiment. For example, in some implementations, the EV value interval may be a variable rather than a fixed value, or the EV value interval and the number of shots may be set without setting the maximum (small) EV value.
S320: and receiving first selection operation of the user on at least two target images in the at least three images.
S330: responding to the first selection operation, synthesizing the at least two target images and outputting a high dynamic range image; and different target brightness areas in the high dynamic range image respectively correspond to different target images.
In this step, the plurality of photographed images may be displayed in the preview image as shown in fig. 4 b. Each image is a complete image containing all sub-areas, i.e. each image contains e.g. the sun, people, trees as shown in fig. 6 a.
And, as shown in fig. 4c, an image first selection operation of the user is received in the last step to determine a target image from among the plurality of captured images. In the figure, the circle of the bold frame is a target image, and the three target images respectively correspond to an over-bright sub-area, an over-dark sub-area and a normal sub-area preset in the image.
Also, in the present step, in response to the first selection operation, the target images are synthesized into an HDR image according to a correspondence between different target luminance regions and different target images in the high dynamic range image.
Specifically, an overly bright sub-region in the synthesized HDR image, such as the region of the sun in the illustration, may use an overly bright region (sun region) in the-3 EV image; normal sub-regions in the composite HDR image, such as the distant view trees in the illustration, may use normal sub-regions in the 0EV image (distant view tree regions); an excessively dark sub-region in the synthesized HDR image, such as a backlit person in the illustration, may use an excessively dark sub-region in +2EV (backlit person region). Thereby, the three target images are combined into one high dynamic range HDR image.
Therefore, according to the method for shooting the image, at least three images with different exposure values are shot according to the preset exposure value adjusting rule; receiving first selection operation of a user on at least two target images in the at least three images; responding to the first selection operation, synthesizing the at least two target images and outputting a high dynamic range image; different target brightness areas in the high dynamic range image correspond to different target images respectively, a user can flexibly select a target image to be synthesized, and the quality and flexibility of shooting HDR images are improved.
Receiving a maximum EV value, a minimum EV value and an EV value interval set by a user; and shooting an image at intervals of 1EV value from the minimum EV value until the EV value reaches or exceeds the maximum EV value, flexibly setting an EV regulation rule by a user, shooting the image according to the EV regulation rule set by the user and synthesizing the image into an HDR image, and realizing the effect of customizing the HDR through the selection of the user. Meanwhile, the user participation degree is higher, and the shooting interest is increased.
Fig. 5 is a flowchart illustrating a method for capturing an image according to an embodiment of the present disclosure, which may be performed by an electronic device, such as a terminal device. In other words, the method may be performed by software or hardware installed in the terminal device. As shown, the method may include the following steps.
S510 to S520 have the same or similar implementation as S110 to S120 in the embodiment of fig. 1 or S311 to S320 in the embodiment of fig. 3, and are not described herein again for brevity of the description.
S531: and dividing a preview image of the electronic equipment into a plurality of target brightness areas.
Fig. 6a is a schematic diagram showing a division into a plurality of luminance areas, and as shown in the figure, a user can customize a plurality of target luminance areas, including: luminance region 1, luminance region 2, luminance region 3, etc., and may be displayed by different colors. Specifically, the user first clicks the "brightness area 1" button, then circles the target area in the preview image, such as selecting the sun and the area nearby in the figure, and clicks "complete selection" after selection, which indicates that "brightness area 1" is complete. Correspondingly, the user can continue to select "brightness region 2" to "brightness region N" to divide the preview screen into any desired regions, and different regions can have different colors as distinctions.
In one implementation, after this step, it may also be detected whether the region setting is complete. And the division of the target luminance region may be changed based on a similar operation after the change operation button is triggered.
S532: and receiving the one-to-one corresponding relation between the target brightness area and the target image set by the user.
Fig. 6b shows a schematic diagram of setting the corresponding relationship, as shown, this step may include: receiving an operation of selecting a target brightness region by a user, for example, receiving an operation of selecting brightness region 1 by the user; receiving an operation of selecting a target image from a plurality of captured images by a user, for example, an operation of selecting a-3 EV photograph; a one-to-one correspondence between the user-selected brightness region and the user-selected target image is set, for example, a one-to-one correspondence between the brightness region 1 and the-3 EV photograph is set.
Likewise, a one-to-one correspondence between the luminance region 2 and the 0EV photograph may be set; the one-to-one correspondence between the luminance regions 3 and the +2EV photos is sequentially executed until the setting of all the regions is completed.
Also, in one implementation, the luminance area 2 having a correspondence relationship with the 0EV photograph or the like (not shown in the figure) may be marked in the same color by specifying the luminance area having a correspondence relationship with the identification mark and the target image.
S533: and synthesizing the target images into HDR images according to the corresponding relation between the target brightness areas and the target images.
Specifically, luminance region 1 in the synthesized HDR image, such as the region of the sun in the illustration, may use luminance region 1 (sun region) in the-3 EV image; luminance region 2 in the composite HDR image, such as the distant view tree in the illustration, may use luminance region 2 in the 0EV image (distant view tree region); the luminance region 3 in the synthesized HDR image, for example, the backlit person in the drawing, may use the luminance region 3 in +2EV (backlit person region). Thereby, the three target images are combined into one high dynamic range HDR image.
Therefore, according to the method for shooting the image, at least three images with different exposure values are shot according to the preset exposure value adjusting rule; receiving first selection operation of a user on at least two target images in the at least three images; responding to the first selection operation, synthesizing the at least two target images and outputting a high dynamic range image; different target brightness areas in the high dynamic range image correspond to different target images respectively, a user can flexibly select a target image to be synthesized, and the quality and flexibility of shooting HDR images are improved.
Receiving a maximum EV value, a minimum EV value and an EV value interval set by a user; and shooting an image at intervals of 1EV value from the minimum EV value until the EV value reaches or exceeds the maximum EV value, flexibly setting an EV regulation rule by a user, shooting the image according to the EV regulation rule set by the user and synthesizing the image into an HDR image, and realizing the effect of customizing the HDR through the selection of the user. Meanwhile, the user participation degree is higher, and the shooting interest is increased.

Meanwhile, the user participation degree is higher, and the shooting interest is increased.
