[0024] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0025] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0026] In order to save processing time when users take photos, thereby providing users with a better photo experience, terminal devices usually use the ZSL method to take frames when taking photos, that is, the image is captured when the device is in the preview state, and after the user clicks to take a photo, the image captured in advance is used for processing to obtain the photo image. When the image previewed in the preview state is very different from the image after the user clicks to take a photo, the image obtained by taking frames using the ZSL method in the related art may not meet the user's expectations. For example, when the device is clicked to take a photo in a dark environment, the flash flashes to fill in the light to increase the brightness of the framing. However, in the framing method of the related art, the image captured in the preview state is still taken, and the image is the image captured before the flash fills in the light, so that the final photo image is darker and has lower clarity, which is inconsistent with the image after the fill in light expected by the user, so that the obtained film is inconsistent with the user's expectations, causing a difference in the photo experience for the user.

[0027] For ease of understanding, Figure 1 It is a schematic diagram of the image captured by the terminal device in the preview state. The image can be saved in the zsl preview queue. Figure 1 From the terminal device settings, it can be seen that the flash is in the on state, which means that when a photo operation (such as a click operation) is performed on the terminal device, the flash flashes to fill in the light of the shooting scene. Figure 1 Click the circular camera control in the middle to perform the operation, such as Figure 2 As shown, the flashlight flashes to fill in the light for the scene being viewed, and at the same time, the camera shoots the scene with the fill in light. In the existing method, the image is still obtained from the ZSL preview queue to generate the following Figure 3 As shown in the film. Figure 3 The brightness and clarity of the film are in line with the user's expectations. Figure 2 There are differences in the images, with lower brightness and clarity.

[0028] To this end, the present disclosure provides a method for taking photos, see Figure 4 The photographing method can be applied to Figure 6 The photographing device 200 shown, Figure 7 The electronic device 800 and the computer readable storage medium shown in the figure. Figure 7 The electronic device 800 shown in the figure is taken as an example, wherein the electronic device can be a mobile phone, a tablet computer, a smart wearable device, or other device with a camera function. Figure 4 The process shown is described in detail, and the photographing method may specifically include the following steps:

[0029] Step S110: When a photo-taking operation on the electronic device is detected, the current state of the flash of the electronic device is obtained.

[0030] A camera application is installed on the electronic device, and an icon corresponding to the camera application can be displayed on the display screen of the electronic device. After the user clicks the icon, the display screen enters the camera interface. At this time, the electronic device is in a preview state, and the camera interface displays the image captured in real time by the camera of the electronic device for the user to preview, and displays the camera controls for taking pictures. Clicking the camera control on the camera interface is a camera operation. In addition to clicking the camera control as mentioned above, you can also press the preset hardware on the electronic device, and the pressing operation is also a camera operation. For example, after the user clicks anywhere on the camera interface of the display screen, the camera of the electronic device focuses, and the click operation can also be considered a camera operation.

[0031] When a photographing operation is performed on an electronic device, the current state of the flash of the electronic device is obtained. For example, the current state may be one of the first state, the second state, and the third state. Among them, the first state refers to the state in which the flash is lit after the photographing operation is detected. Optionally, the electronic device is in the first state, and after the photographing operation is detected, the flash of the electronic device may be lit within a preset time period and then extinguished. After the next photographing operation is performed on the electronic device, the flash is still lit and extinguished according to this rule, wherein the preset time period is a very short time period, for example, the preset time period may be between a few milliseconds and tens of milliseconds. The second state is the state in which the flash is lit before the photographing operation is detected. For example, for an electronic device in the second state, after entering the photographing interface, the flash is lit until the photographing interface is exited. The third state is the state in which the flash is not turned on. It is easy to understand that the flash of the electronic device in the third state is not lit during the entire preview and photographing process, that is, the flash does not fill the entire preview and photographing process.

[0032] As a method, the current state of the flashlight is obtained by obtaining the state tag of the flashlight of the electronic device. For example, the state tag is 00, which indicates that the current state of the flashlight is the third state. The state tag is 10, which indicates that the current state of the flashlight is the second state. The state tag is 11, which indicates that the current state of the flashlight is the first state.

[0033] The state of the electronic device may be manually set by the user, for example, by clicking a setting control on the camera interface, and selecting any one of the first state, the second state and the third state as the current state through the setting control.

[0034] Alternatively, when the electronic device is in the photo taking interface, the brightness of the environment in which the electronic device is located is detected, and if the brightness is higher than a preset brightness, the third state is set as the current state. If the brightness is lower than or equal to the preset brightness, the first state or the second state is determined as the current state according to the user's setting.

[0035] Step S120: If the current state is the first state, obtain a first image from a captured image sequence, wherein the first state is a state in which the flash is on after a photographing operation is detected, and the captured image sequence is composed of images captured by the electronic device after the photographing operation is detected.

[0036] In one case, the current state is the first state. For the electronic device in the first state, before detecting that the user performs a photo operation on the electronic device, the flash does not light up. It can be understood that the flash does not fill in the light for the shooting scene. In this case, the brightness and clarity of the image captured by the camera of the electronic device are low. Accordingly, the brightness and clarity of the image presented on the photo interface for the user to preview are low. For the electronic device in the first state, after detecting that the user performs a photo operation on the electronic device, the flash is controlled to light up. It can be understood that the flash fills in the light for the shooting scene. In this case, the brightness and clarity of the image that can be captured by the camera of the electronic device are high. Accordingly, the brightness and clarity of the image presented on the photo interface for the user to preview are high. In order to obtain a better quality photographed image, for the electronic device in the first state, a first image is acquired from a sequence of photographed images.

[0037] Step S130: Process the first image to obtain a first photographed image.

[0038] The processing performed on the first image may include filtering, cutting, format conversion and the like, thereby obtaining a first photographed image.

[0039] The first photographed image obtained in this embodiment can be understood as the finished image of this shooting. Figure 5As shown, compared with the related art Figure 3 As shown in the film, the film obtained in this embodiment has stronger brightness and richer details, which improves the photo effect.

[0040] Optionally, the photographed images can be stored in a local album of the electronic device, so that the user can view them in time. The electronic device can also store them in a cloud connected to the electronic device.

[0041] The photographing method provided in this embodiment, when a photographing operation on an electronic device is detected, obtains the current state of the flash of the electronic device. If the current state is the first state, the first state refers to the state where the flash is on after the photographing operation is detected. Then, the first image is obtained from the captured image sequence, and the first image is processed to obtain a first photographed image. The captured image sequence is composed of images captured by the electronic device after the photographing operation is detected. Since the images in the captured image sequence are captured after the flash is filled in, they have the characteristics of high brightness and rich details. Compared with the method of obtaining a film by using the image captured before the flash is flashed in the related art, the first photographed image obtained thereby has the characteristics of high brightness and high definition, thereby improving the quality of the film, so that the obtained film is consistent with the photo expected by the user.

[0042] In one embodiment, step S120 may be performed in the following manner to obtain the first image from the captured image sequence: configure the preset parameters to a preset state, for example, the preset parameters may be a zsl untenable meta parameter, and the preset state refers to the value of the zsl untenable meta parameter being configured to 0 or 1. Then, according to the preset parameters of the preset state, preset data is generated, and the generated preset data carries the preset parameters of the preset state. Optionally, the preset parameters of the preset state carried in the preset data may be set not to be allowed to be changed, so that the stability of the transmission of the preset parameters of the preset state is improved by the preset data. Then, according to the preset data, the first image is obtained from the captured image sequence.

[0043] Optionally, the captured image sequence stores multiple frames of images captured after the camera operation is detected, and the multiple frames of images can be stored in the captured image sequence in the order of capture. In another embodiment, step S120 can also be to obtain the first image of the target frame number from the captured image sequence. The first image of the target frame number can be an image of any target frame number in the captured image sequence, or can be a continuous image of the target frame number captured after the camera operation is detected in the captured image sequence. The target frame number can be one frame. The target frame number can also be multiple frames, for example, the target frame number is 8 frames, 9 frames, etc.

[0044] In one implementation, step S130 may be performed in the following manner, for example, the first image is in a raw format, and the first image is converted into a target format to obtain a first photographed image, for example, the target format may be a jpeg format, a png format, a webp format, a bmp format, etc.

[0045] The processing of the first image is not limited to the above-mentioned format conversion, and the first image may also be processed as follows. In another embodiment, the first image of the target frame number may be processed by a multi-frame noise reduction algorithm (MFNR) to obtain the first photographed image, thereby obtaining a finished film. For example, the multi-frame noise reduction algorithm may perform noise reduction, enhancement, segmentation, merging, and other processing on the first image.

[0046] Exemplarily, the first image may be processed by a multi-frame noise reduction algorithm in the following manner: the first image in raw format is converted into a first image in RGB (red green bleu) format. Since the data structure of the first image in RGB format is relatively simple compared to the first image in raw format, the first image in RGB format is convenient for subsequent processing. The size of the first image in RGB format may be adjusted to fit the size of the display screen of the electronic device. The first image in RGB format after the size adjustment is then encoded to obtain a first photographed image in, for example, JPEG format. During the encoding process, the size of the image will be compressed, so that the first photographed image in JPEG format finally obtained can occupy smaller storage resources of the electronic device.

[0047] In this implementation, the first image is processed by a multi-frame noise reduction algorithm, thereby obtaining a first photographed image, thereby improving the quality of the film.

[0048] In another case, if the current state is not the first state, for example, the current state is the second state or the third state, a second image is obtained from the preview image sequence, the second state is a state where the flash is on before the photographing operation is detected, the third state is a state where the flash is not on, and the preview image sequence is composed of images collected by the electronic device before the photographing operation is detected. The second image is then processed to obtain a second photographed image.

[0049] When the current state is the second state or the third state, the brightness of the image before and after the electronic device performs a photographing operation is not much different, so the second photographed image can be directly obtained by using the preview image sequence collected in advance before the photographing operation, which improves the speed of photographed image output so that the user can quickly view the second photographed image. It can be understood that the second photographed image is a finished image obtained when the electronic device is in the second state or the third state.

[0050] As a method, the second image can be obtained from the preview image sequence by configuring the preset parameters as the remaining states. For example, the preset parameters can be zsl untenable meta parameters. If the aforementioned preset state is 1, the remaining states are 0. If the aforementioned preset state is 0, the remaining states are 1. Then, according to the preset parameters of the remaining states, the remaining data are generated. The generated remaining data carries the preset parameters of the remaining states. Optionally, the preset parameters of the remaining states in the remaining data can be set to not be changed, thereby improving the stability of the transmission of the preset parameters of the remaining states. Then, according to the remaining data, the second image is obtained from the preview image sequence.

[0051] Optionally, the preview image sequence stores multiple frames of images captured before the photo-taking operation is detected, and the multiple frames of images can be stored in the preview image sequence in the order of capture. As a method, obtaining the second image from the preview image sequence can be to obtain the second image of the target frame number from the preview image sequence. The second image of the target frame number can be any image of the target frame number in the preview image sequence, or can be a continuous image of the target frame number captured before the photo-taking operation obtained in the preview image sequence. The target frame number can be one frame. The target frame number can also be multiple frames, for example, the target frame number is 8 frames, 9 frames, etc.

[0052] In one implementation, the second image is in raw format, and the second image in raw format is converted to obtain a second photographed image in a target format, wherein the target format may be jpeg format, png format, webp format, bmp format, etc.

[0053] The processing of the second image is not limited to the above-mentioned format conversion method, and the second image can also be processed in the following manner. In another embodiment, the second image of the target frame number can be processed by a multi-frame noise reduction algorithm to obtain the second photographed image, thereby obtaining a film. For example, the multi-frame noise reduction algorithm can perform noise reduction, enhancement, segmentation, merging, etc. on the second image.

[0054] Exemplarily, the second image may be processed by a multi-frame noise reduction algorithm in the following manner: the second image in raw format is converted into a second image in RGB format by color space conversion. Since the second image in RGB format has a relatively simple data structure compared to the second image in raw format, the second image in RGB format is convenient for subsequent processing. The size of the second image in RGB format may be adjusted to fit the size of the display screen of the electronic device. The resized second image in RGB format is then encoded to obtain a second photographed image in, for example, JPEG format. During the encoding process, the size of the image is compressed, so that the second photographed image in JPEG format obtained in the end may occupy less storage resources of the electronic device.

[0055] In this implementation, the second image is processed by a multi-frame noise reduction algorithm, thereby obtaining a second photographed image, thereby improving the quality of the film.

[0056] In this implementation, the second image is processed by a multi-frame noise reduction algorithm to obtain a photographic image, thereby improving the quality of the photographic image.

[0093] In summary, the present disclosure provides a photographing method, device, electronic device and medium. When a photographing operation is detected on an electronic device, the current state of the flash of the electronic device is obtained. If the current state is a first state, the first state refers to a state in which the flash is on after the photographing operation is detected. Then, a first image is obtained from a captured image sequence, and the first image is processed to obtain a first photographed image. The captured image sequence is composed of images captured by the electronic device after the photographing operation is detected. Since the images in the captured image sequence are captured after being filled with flash light, they have the characteristics of high brightness and rich details. Compared with the method of obtaining a film using images captured before the flash is flashed in the related art, the first photographed image obtained thereby has the characteristics of high brightness and high definition, thereby improving the quality of the film, so that the obtained film is consistent with the photo expected by the user.
