Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.

Currently, HDR technology is widely used in the field of smart camera technology. However, when an HDR image is captured by an electronic device using the HDR technology, generally, a capture scene of a capture preview interface captured by a current camera component is detected first, and exposure parameter values are determined based on the capture scene of the current capture preview interface, so that the electronic device can capture a plurality of photos for photo composition with different exposure parameter values according to the determined exposure parameter values.

Then, the electronic device performs photo synthesis on the multiple photos with different exposure parameter values for photo synthesis to obtain a final HDR image.

Therefore, when the traditional HDR technology is used for synthesizing photos, only the photos obtained are synthesized, the exposure of the N photos used for synthesizing the HDR image cannot be changed according to different requirements of a user, and the requirement that the user can obtain different HDR images according to different requirements cannot be met, so that the use experience of the user is influenced.

In order to solve the above problem, embodiments of the present invention provide a method, an electronic device, and a medium for processing a photo, which enable a user to freely combine photos with different exposure parameters to obtain an HDR image meeting the needs of the user, improve the visual effect of the HDR image, and improve the user experience.

Fig. 1 is a flowchart illustrating a photo processing method according to an embodiment of the present invention. As shown in fig. 1, the method applied to photo processing of an electronic device includes:

s101, receiving a first input under the condition that N first photos with different exposure parameter values are displayed.

And S102, responding to the first input, and synthesizing the M first photos according to the exposure parameters of the M first photos in the N first photos to obtain a second photo.

Wherein M is a positive integer less than or equal to N, and N is a positive integer greater than 2.

And S103, displaying the second photo.

According to the embodiment of the invention, the electronic equipment receives the first input of the user to the first control, and the electronic equipment can synthesize the selected M first photos for photo synthesis to finally obtain and display the second photos meeting the user requirements, so that the use experience of the user is improved.

Optionally, in some embodiments of the present invention, the first input may be a selected input of the exposure parameters of the M first photos among the N first photos based on the user's own requirement for the HDR image. At this time, the user can autonomously select the M first photos for synthesizing the HDR image according to different requirements of the user on the HDR image, thereby improving the user experience.

The first input may also be a determination input of exposure parameters of the M photos automatically recommended by the user for the electronic device. At the moment, the user can directly perform photo synthesis according to the M first photos automatically recommended by the electronic equipment without re-selection, so that the use experience of the user is improved.

Alternatively, in some embodiments of the present invention, the exposure parameter may be an exposure compensation Value (EV), the EV is increased by 1, the exposure amount is increased by 2 times, and when the ambient brightness and the sensor are the same, the brightness of the corresponding obtained picture should be increased by one time in a linear interval.

As shown in fig. 2, fig. 2 is a schematic diagram of a second interface according to an embodiment of the invention. As can be seen from fig. 2, N first photographs (N is a positive integer greater than 2) with different exposure parameter values are displayed on the second interface, where each photograph may display a corresponding EV, and the N first photographs with different exposure parameter values may be referred to as EV packets.

After the user views the N first photos with different exposure parameter values displayed on the second interface, the user can control the electronic device to synthesize the photos through the first control on the second interface.

According to some embodiments of the invention, the first photos with different exposure parameter values are displayed on the second interface, so that the user can visually check the photos for synthesizing the HDR image on the second interface, the user can freely select the photos according to the requirements of the user, and the user experience is improved.

Optionally, in some embodiments of the present invention, with continued reference to fig. 2, on the second interface, the M first photos selected by the user for photo synthesis may be displayed with different distinctions of the identification pattern.

Under the condition that N first photos with different exposure parameter values are displayed, after the electronic equipment responds to the input of a user to the first control, the electronic equipment can synthesize the M first photos according to the exposure parameter values of the M first photos related to the first input in the N first photos to obtain a second photo. Wherein M is a positive integer less than or equal to N.

Optionally, in some embodiments of the present invention, before S101, the user may further make a sixth input to a second control in the shooting preview interface.

As shown in fig. 3, fig. 3 is a schematic diagram of a shooting preview interface according to an embodiment of the present invention. As shown in fig. 3, the shooting preview interface may be an interface of the electronic device in a shooting mode, where a shooting preview image 31 collected by the camera component is displayed on the shooting preview interface, and the second control is used to represent a control for setting the EV combination. And displaying the first interface by the user through a sixth input of the second control.

Secondly, the electronic equipment receives a sixth input of the user to the second control in the shooting preview interface, and responds to the sixth input to display the first interface. As shown in fig. 4, fig. 4 is a schematic view of a first interface according to an embodiment of the present invention.

As can be seen from fig. 4, taking the exposure compensation value as the exposure parameter, the first interface is provided with a first exposure parameter interval of the exposure compensation value. For example, the Min EV + value, the Max EV + value, the Min EV-value, and the Max EV-value together comprise a first exposure parameter interval, and the Min EV + value corresponds to a first adjustment control, the Max EV + value corresponds to a first adjustment control, the Min EV-value corresponds to a first adjustment control, and the Max EV-value corresponds to a first adjustment control. In addition, a first Step length value of the adjustment Step length EV Step and a second adjustment control corresponding to the first Step length value are also displayed on the first interface.

For example, the first exposure parameter interval: if the Min EV + value is 1, the Max EV + value is 2, the Min EV-value is-1, the MaxEV-value is-2, and the EV Step is 0.5, the electronic device may obtain a first picture with the following exposure compensation values when shooting according to the first exposure parameter interval and the adjustment Step length: +0EV, +1EV, +1.5EV, +2EV, -0EV, -1EV, -1.5EV, -2 EV.

Next, if the user wants to adjust the EV parameter in the HDR shooting mode, a second input may be further made to at least one of the first adjustment control and the second adjustment control to adjust the value of the EV parameter. The electronic device may continue to respond to a second input of the user to at least one of the first adjustment control and the second adjustment control, and obtain the exposure parameter values of the subsequently taken N first photos, so as to subsequently take the photos according to the obtained exposure parameter values of the first photos.

With some embodiments of the invention, the user may first make a sixth input to the second control on the capture preview interface to enter the setting interface (first interface) of EV parameters. Secondly, a user can set exposure compensation parameters of N first pictures shot by the HDR on the first interface, so that the electronic equipment can shoot the first pictures according to the requirements of the user, and the use experience of the user is improved.

Next, the electronic device may also receive a third input by the user while the electronic device is in the HDR photographing mode.

The electronic device can respond to the third input, and then start to take N first pictures with different exposure parameter values according to the acquired N different exposure parameter values. It should be understood that the electronic device would take N first pictures within the first exposure parameter interval according to the EV Step value.

By some embodiments of the present invention, in the HDR shooting mode, the electronic device, in response to a third input from the user, may shoot N first photos with different exposure parameter values, so that when synthesizing an HDR image, the electronic device may have multiple low dynamic range images, so as to improve the visual effect of the HDR image.

Optionally, in some embodiments of the present invention, the first exposure parameter interval and the first step length value of the adjustment step length displayed on the first interface may be recommended values determined by the electronic device according to target shooting scene information of the shooting preview image displayed on the shooting preview interface.

For example, the electronic device may determine target shooting scene information corresponding to a shooting preview image displayed on a shooting preview interface according to the shooting preview image displayed on the shooting preview interface, and an Automatic Exposure Control (AEC) module in the electronic device may determine a first exposure parameter interval and a first step value according to the target shooting scene information, and recommend the first exposure parameter interval and the first step value to the user as the first exposure parameter interval and the first step value in the HDR shooting mode.

Optionally, in some embodiments of the present invention, a plurality of selection controls for shooting scene information may be further displayed on the shooting preview interface, so that if the target shooting scene information corresponding to the shooting preview image identified by the electronic device is not accurate, a user may adjust the target shooting scene information corresponding to the shooting preview image displayed on the shooting preview interface to the shooting scene information selected by the user through input of the selection controls for the shooting scene information.

According to some embodiments of the invention, a user can directly control the electronic device to take a picture according to the first exposure parameter interval and the first step length value recommended by the electronic device through the target shooting scene information, or can adjust and input at least one of the first exposure parameter interval and the first step length value, so that the electronic device takes a picture according to the adjusted first exposure parameter interval and the first step length value, thereby meeting different requirements of different users, improving the operation flexibility of the user, and improving the use experience of the user.

Optionally, in some embodiments of the present invention, before S102, further including:

the electronic equipment can determine the exposure parameter values of the M first pictures in the N first pictures according to the image histogram information corresponding to the shot preview image. The image histogram information refers to statistical data histogram information, which can be used to indicate the pixel distribution of each luminance interval on one RAW format image, for example, an 8-bit (bit) statistical data histogram indicates the distribution number of 256 luminance pixels, 0-255, on the whole image.

Optionally, in some embodiments of the present invention, the electronic device may first determine first luminance information corresponding to the first luminance interval and second luminance information corresponding to the second luminance interval of the image histogram information corresponding to the captured preview image. The first brightness interval pushdown zone may be a brightness interval (start-end) desired to be brightened, and the second brightness interval pushup zone may be an interval (start-end) desired to be darkened by depressing a high light, and the first brightness interval and the second brightness interval may be brightness intervals preset by the electronic device (not to be changed by the user) or brightness intervals preset by the user.

Next, the electronic device determines a second exposure parameter interval based on the first luminance information and the second luminance information. That is, the electronic apparatus calculates the value of dark region position dark Pos and the value of bright region bright Pos using the first luminance information and the second luminance information by expression (1) and expression (2), respectively.

The dark Pos is a weighted average of the luminance (first luminance information) of the statistical data histogram of the captured preview image in the first luminance section (pushdown zone). (1)

The brightness Pos is a weighted average of the luminance (second luminance information) of the statistical data histogram of the captured preview image in the second luminance zone (pushup zone). (2)

The dark Pos is used for representing the maximum value of EV + in M first pictures, and when the calculated dark Pos is larger than a dark Max value preset in the electronic equipment, the dark Pos value can select a Min EV + value set by a user; if the dark Pos is smaller than the dark Min preset in the electronic equipment, the dark Pos value can select the Max EV + value set by the user; if the dark Pos is in the dark Min-dark Max range, the dark Pos value is obtained by interpolation according to the Max and Min of the EV + range set by the user.

The bright Pos is used for representing the minimum value of EV-in the M first photos, and when the calculated bright Pos is larger than a bright Max value preset in the electronic equipment, the bright Pos value can select a MaxEV-value set by a user; if the bright Pos value is smaller than the bright Min preset in the electronic equipment, the bright Pos value can select the Min EV-value set by the user; if the bright Pos is in the range of bright Min-bright Max, the value of bright Pos can be obtained by interpolation calculation according to the Max and Min of EV-range set by the user.

After the final dark Pos value and the bright Pos value are obtained through the above calculation, the electronic device may obtain the range of EV parameter values (dark Pos-bright Pos) of the M first photos used for photo synthesis, and use the range of EV parameters (dark Pos-bright Pos) as the second exposure parameter interval.

Optionally, in some embodiments of the present invention, when determining the second exposure parameter interval, the electronic device may not only need to calculate the expression (1) and the expression (2) above, but also may add analysis on parameters such as definition and saturation of the image, and obtain the second exposure parameter interval according to the (dark Pos-bright Pos) value, the definition, and the saturation in a comprehensive manner.

Optionally, in some embodiments of the invention, after obtaining the second exposure parameter interval, the electronic device may determine M first photos for photo composition from the (EV + to EV-) range indicated by the second exposure parameter interval (dark Pos-bright Pos) among the N first photos.

For example, if the exposure parameters of the obtained 8 first pictures are: +0EV, +1EV, +1.5EV, +2EV, -0EV, -1EV, -1.5EV, -2EV, and the range of EV parameter values (dark Pos-bright Pos) obtained by the above calculation is (+1EV, -1.5EV), then the exposure parameters for the electronic device to obtain 6 first photographs for photograph composition in 8 first photographs are: +1EV, +1.5EV, +2EV, -0EV, -1EV, -1.5 EV.

According to some embodiments of the invention, the electronic device can directly recommend the combination of the first photos for synthesizing the HDR image for the user through the image histogram information corresponding to the preview image, so that the user can directly perform photo synthesis according to intelligent recommendation, and the use experience of the user is improved.

Optionally, in some embodiments of the present invention, after S103, the method for processing a photo further includes:

if the user is not satisfied with the brightness of the target area in the second picture, a fourth input, such as a frame selection input, may be made to the target area. Next, the electronic device may display an adjustment prompt in response to a fourth input by the user into the target area of the second photograph. And the adjustment prompt information is displayed in a preset control form. The preset control may be used to indicate that the brightness corresponding to the target area is to be "brightened" or the preset control may be used to indicate that the brightness corresponding to the target area is to be "darkened".

Optionally, in some embodiments of the present invention, if the fifth input is an input for a preset control indicating that brightness corresponding to the target area is to be "brightened", indicating that the user considers that the brightness corresponding to the target area is too dark, and wants to brighten, the electronic device may adjust the first brightness interval (pushdown zone) according to brightness information corresponding to the target area to obtain a third brightness interval (pushdown zone), where the third brightness information corresponding to the third brightness interval is brightness of the statistical data histogram of the captured preview image in the third brightness interval (pushdown zone).

Then, the electronic device may recalculate the third luminance information and the second luminance information according to the expression (1) and the expression (2) to obtain (dark Pos-bright Pos), so as to adjust the second exposure parameter interval to obtain a third exposure parameter interval.

Finally, after obtaining the third exposure parameter interval, the electronic device may determine, again from the N first photos, M first photos for photo synthesis according to the (EV + to EV-) range represented by the third exposure parameter interval (dark-bright Pos), so as to ensure that the brightness of the area having the brightness of the target area in the second photo synthesized by using the M newly obtained first photos is increased.

Optionally, in some embodiments of the present invention, if the fifth input is a preset input indicating that the brightness corresponding to the target area is to be "darkened", that is, the user regards that the brightness corresponding to the target area is too bright, and wants to dim, the electronic device may adjust the second brightness interval (pushup zone) according to the brightness information corresponding to the target area, to obtain a fourth brightness interval (pushup zone), where the fourth brightness information corresponding to the fourth brightness interval is the brightness of the statistical data histogram of the captured preview image in the fourth brightness interval (pushup zone).

Then, the electronic device may recalculate the fourth luminance information and the first luminance information according to the expression (1) and the expression (2) to obtain (dark Pos-bright Pos), so as to adjust the second exposure parameter interval to obtain the third exposure parameter interval.

Finally, after obtaining the fourth exposure parameter interval, the electronic device may re-determine M first photos for photo composition from the N first photos according to the (EV + to EV-) range represented by the third exposure parameter interval (dark-bright Pos), so as to ensure that the brightness of the area having the brightness of the target area in the second photo composed by using the re-obtained M first photos is all reduced.

According to some embodiments of the present invention, after the user sees the second photo obtained after the synthesis, if the user is not satisfied with the brightness of a certain region in the second photo, the user may return to the second interface shown in fig. 2 again according to the adjustment prompt information to reselect the first photo used for synthesizing the HDR image, and the electronic device may also perform, based on the input of the adjustment prompt information by the user, selection recommendation of M photos again according to the adjustment requirement of the user on the target region, so as to improve the user experience.

Optionally, in some embodiments of the present invention, the electronic device may further calculate a dynamic range of the second photo, and display the calculated dynamic range on the second photo as a reference opinion of whether the HDR image is saved by the user. The larger the dynamic range is, the better the quality of the image is objectively represented, and in addition, the electronic device may also display the definition and/or the protection degree of the second photo on the second photo as a reference opinion of whether the HDR image is saved by the user.

Based on the specific implementation of the photo processing method provided by the above embodiment, correspondingly, the invention further provides a specific implementation of the electronic device. Please refer to fig. 5.
