Description

Shooting method and electronic equipment

Technical Field

The embodiment of the application relates to the technical field of optical imaging, in particular to a shooting method and electronic equipment.

Background

At present, in order to meet the photographing requirements in different scenes, electronic devices are generally configured with a plurality of cameras. Among these cameras may include cameras of multiple focal lengths, e.g., short-focus wide-angle cameras, mid-focus cameras, and tele-cameras, among others. The cameras with different focal lengths can correspond to different viewing ranges and zoom magnifications.

When a user takes a picture using an electronic device with multiple cameras, the electronic device may switch cameras of different focal lengths (i.e., optical zoom) for capturing the image. In addition, the electronic equipment can also adjust the view finding range by combining a software processing mode of digital zooming so as to meet various shooting scenes.

It should be understood that when the electronic device is combined with digital zoom (or called digital zoom), as the zoom factor increases, the viewing range displayed by the electronic device is adjusted to be a part of the shot scene, and the Field of View (FOV) corresponding to the camera is gradually decreased. Thus, the electronic device needs to crop more pixels from the original resolution image, and the remaining pixels can be formed into the original resolution image through a software interpolation algorithm. In this process, the image finally generated by the electronic device inevitably causes a loss of definition.

Disclosure of Invention

The application provides a shooting method and electronic equipment, so that the electronic equipment can reduce the definition loss of a shot image in a zoom magnification shooting scene, and the user experience of the electronic equipment in the zoom magnification shooting scene can be improved.

In order to achieve the technical purpose, the following technical scheme is adopted in the application:

in a first aspect, the present application provides a shooting method, which may include: in response to an operation triggering the camera function, a camera application of the electronic device is launched. At this time, the electronic device displays a first preview image, and the zoom magnification corresponding to the first preview image is a first magnification. Wherein the first magnification may be a preset magnification. If the preset magnification is 1 time (1 ×), the electronic device displays the first preview image, which is a 1 × image.

After the electronic device receives the first operation, the electronic device may determine a pixel signal combination mode according to a preset rule, and generate a second preview image according to the preset pixel signal combination mode (e.g., the first pixel signal combination mode or the second pixel signal combination mode), so that the electronic device displays the second preview image. Wherein. The first operation instructs the electronic apparatus to adjust the zoom magnification to a target magnification (e.g., a second magnification). Thus, the second preview image is an image at the zoom magnification that is the target magnification.

For example, the preset rule may be: when the target magnification is a zoom magnification value smaller than 3x, the electronic device forms a preview image (i.e., a second preview image) in a manner that the first pixel signals are combined. Triggering a shooting key, identifying the brightness of the shooting environment of the electronic equipment, and if the brightness is higher than a first preset threshold value, generating a shooting image by the electronic equipment in a second pixel signal combination mode; and if the brightness is lower than a first preset threshold value, the electronic equipment generates a shot image in a first pixel signal combination mode.

In a second aspect, the present application further provides a shooting method, which may include: in response to an operation triggering the camera function, a camera application of the electronic device is launched. The electronic equipment displays a first preview image, and the zoom magnification corresponding to the first preview image is a first magnification. When the electronic equipment displays the first preview image, if the electronic equipment receives a first operation, the first operation instructs the electronic equipment to adjust the zoom magnification to a second magnification, and the second magnification is smaller than the preset magnification. That is, when the first operation received by the electronic device indicates that the zoom magnification of the electronic device is less than the preset magnification. For example, the second magnification is less than 3 ×.

In this case, the electronic device generates a preview image (i.e., a second preview image) by combining the first pixel signals, and a display screen of the electronic device is used for displaying the second preview image, so that a user can view the real-time preview image through the display screen. And the zoom magnification corresponding to the second preview image is a second magnification. In response to an operation in which the photographing key is triggered, the electronic apparatus determines the brightness of the photographing environment in which it is located. If the brightness is larger than a first preset threshold value, the electronic equipment generates a shot image in a second pixel signal combination mode; and if the brightness is less than or equal to a first preset threshold value, the electronic equipment generates a shot image in a first pixel signal combination mode.

It can be understood that different pixel signal combination methods have different shooting characteristics. Generally, in a zoom shooting scene, when the shooting environment brightness is insufficient, an image is generated by adopting a first pixel signal combination mode, so that the light sensitivity of an image sensor can be improved, and the signal-to-noise ratio can be increased; under the scene that the shooting environment brightness is sufficient, the image is generated in a second pixel signal combination mode, and the definition of the generated image can be improved in the image with the zooming magnification. That is, in an environment with insufficient luminance, it is appropriate to generate an image by the first pixel signal combination method, and in an environment with sufficient luminance, it is appropriate to generate an image by the second pixel signal combination method. Therefore, when the shooting key of the electronic equipment is triggered, the brightness of the shooting environment where the electronic equipment is located is determined, and the pixel signal combination mode is adjusted according to the brightness, so that the loss of image definition is reduced when the electronic equipment is in zooming magnification, the generated image is clearer, and the user experience of the electronic equipment in a zooming magnification shooting scene is improved.

With reference to the second aspect, in a possible implementation, when the electronic device generates the captured image by using the second pixel signal combination method, the method may specifically include: the electronic equipment outputs an original image in a second pixel signal combination mode, wherein the zooming multiplying power of the original image is a first multiplying power, and the first multiplying power is larger than a second multiplying power. And performing cropping processing on the original image to generate a shot image, wherein the shot image is an image with a zooming magnification of a second magnification.

In the second pixel signal combination mode, the resolution of the image directly output by the second pixel signal combination mode is not consistent with the resolution corresponding to the second magnification and is larger than the image corresponding to the second resolution. Therefore, the electronic apparatus performs clipping processing on the original image output in the second pixel signal combination manner so that the clipped original image is an image of which zoom magnification is the second magnification.

With reference to the second aspect, in another possible implementation, before the electronic device generates the captured image in the second pixel signal combination manner after the brightness is greater than the first preset threshold, the method may further include: the electronic equipment stops outputting the image frame in a first pixel signal combination mode; the electronic equipment stops displaying the second preview image; the electronic device switches from the first pixel signal combination mode to the second pixel signal combination mode.

It can be understood that, when the electronic device needs to switch the pixel signal combination mode, the first pixel signal combination mode is switched to the second pixel signal combination mode. In this process, the electronic device needs to undergo start-stop switching, that is, the current first pixel signal combination mode is stopped, and at this time, the electronic device stops displaying the second preview image. And after the electronic equipment completes switching and outputs the image frame in a second pixel signal combination mode, the electronic equipment generates a shot image.

With reference to the second aspect, in another possible implementation, in the method, if the brightness is greater than a first preset threshold, the electronic device generates the captured image in a second pixel signal combination manner; if the brightness is smaller than or equal to the first preset threshold value, the electronic equipment generates a shot image in a first pixel signal combination mode. The above method may further comprise: and the electronic equipment generates a third preview image in a first pixel signal combination mode and displays the third preview image.

Wherein the electronic device generates the shot image after the response shot key is triggered. After the shooting action is finished, if the electronic equipment is still in a shooting stage, the electronic equipment still generates a preview image (namely a third preview image) in a first pixel signal combination mode.

With reference to the second aspect, in another possible implementation, the generating, by the electronic device, a captured image by using a first pixel signal combination method may specifically include: the electronic equipment outputs a multi-frame image frame in a first pixel signal combination mode; based on a first image fusion algorithm, the electronic equipment generates a shot image according to a plurality of frames of image frames. Wherein the first image fusion algorithm at least comprises: one of a multi-frame noise reduction algorithm, a high dynamic range algorithm, a high dynamic super-resolution algorithm and a super-resolution algorithm based on a human face.

With reference to the second aspect, in another possible implementation, the performing a cropping process on the original image to generate a captured image specifically may include: cutting an original image to obtain a preprocessed image frame; based on the second image fusion algorithm, the electronic equipment generates a shot image according to the multi-frame preprocessing image frame. Wherein the second image fusion algorithm at least comprises: one of a multi-frame noise reduction algorithm, a high dynamic range algorithm, a high dynamic super-resolution algorithm and a super-resolution algorithm based on a human face.

It is understood that, in order to improve the quality of an image generated in zoom magnification shooting, the first image fusion algorithm (or the second image algorithm) is employed so that the image quality is higher. For example, the definition of the image is improved, and the dynamic range of the image is increased, so that the user experience of the electronic equipment in a zoom magnification shooting scene can be improved.

With reference to the second aspect, in another possible implementation, the electronic device includes one or more front cameras, and the electronic device implements a shooting function through the one or more front cameras; the second multiplying power is a multiplying power value of the first multiplying power interval, wherein the first multiplying power interval is 0.8 multiplying power to 1.9 multiplying power.

Or; the electronic equipment comprises one or more rear cameras, and the electronic equipment realizes a shooting function through the one or more rear cameras; the second multiplying power is a multiplying power value of a second multiplying power interval, wherein the second multiplying power interval is 1.0 multiplying power to 2.9 multiplying power.

In a third aspect, the present application further provides a shooting method, where the method may include: in response to an operation triggering the camera function, a camera application of the electronic device is launched. The electronic equipment displays a first preview image, and the zoom magnification corresponding to the first preview image is a first magnification. When the electronic equipment displays the first preview image, if the electronic equipment receives a first operation, the first operation instructs the electronic equipment to adjust the zoom magnification to a third magnification, and the third magnification is larger than or equal to a preset magnification. That is, when the first operation received by the electronic device indicates that the zoom magnification of the electronic device is greater than or equal to the preset magnification. For example, the zoom magnification of the electronic apparatus is 3 ×, or more.

And determining the brightness of the shooting environment of the electronic equipment, and if the brightness is less than or equal to a first preset threshold value, generating a second preview image by adopting a first pixel signal combination mode. And if the brightness is larger than the first preset threshold value, generating a second preview image by adopting a second pixel signal combination mode. And the zoom magnification corresponding to the second preview image is a third magnification.

When the electronic equipment displays a preview interface, the electronic equipment determines the brightness of the current shooting environment in real time, and if the brightness of the current shooting environment is determined to be a highlight shooting environment, a preview image (namely a second preview image) is generated in a second pixel signal combination mode; and if the environment is determined to be a dark light shooting environment, generating a second preview image by adopting the first pixel signal combination mode. The electronic equipment is real-time, so that when the electronic equipment is in zooming magnification, the loss of image definition is reduced, the generated image is clearer, and the user experience of the electronic equipment in a zooming magnification shooting scene is improved.

In a possible implementation, after the generating a second preview image by using the first pixel signal combination method if the brightness is less than or equal to the first preset threshold, and the zoom magnification corresponding to the second preview image is the third magnification, the method may further include: determining the current brightness of the shooting environment of the electronic equipment; if the current brightness is larger than a first preset threshold value, the electronic equipment is switched from a first pixel signal combination mode to a second pixel signal combination mode; and generating a third preview image by adopting a second pixel signal combination mode, wherein the zoom magnification corresponding to the third preview image is a third magnification.

In the process that the electronic device displays the preview image (i.e., the second preview image), the electronic device can adjust the pixel signal combination mode in real time according to the brightness of the shooting environment where the electronic device is located. Specifically, if the brightness is greater than a first preset threshold, the electronic device outputs an image frame in a second pixel signal combination mode; the brightness is smaller than or equal to a first preset threshold value, and the electronic equipment outputs an image frame in a first pixel signal combination mode. The pixel signal combination mode can be adjusted according to the brightness in real time, and good use experience can be provided for users in the process of displaying preview images. And the preview image which is seen by the user in real time has the same effect as the image generated by shooting, thereby providing good use experience for the user.

In a third aspect, in another possible implementation, if the brightness is greater than the first preset threshold, a second preview image is generated by using a second pixel signal combination method, and after a zoom magnification corresponding to the second preview image is a third magnification, the method may further include: determining the current brightness of the shooting environment where the electronic equipment is located; if the current brightness is smaller than or equal to a second preset threshold, the electronic equipment is switched from the second pixel signal combination mode to the first pixel signal combination mode, and the second preset threshold is smaller than the first preset threshold; and generating a fourth preview image by adopting a first pixel signal combination mode, wherein the zoom magnification corresponding to the fourth preview image is a third magnification.

In a third aspect, in another possible implementation, when the electronic device generates the second preview image by using the first pixel signal combination method, the method may further include: in response to the shooting key being triggered, the electronic device generates a shot image in a first pixel signal combination mode. When the electronic device generates the second preview image by using the second pixel signal combination method, the method may further include: in response to the shooting key being triggered, the electronic device generates a shot image in a second pixel signal manner.

It can be understood that, when the electronic device generates the preview image in the corresponding pixel signal combination mode, the shooting key is triggered, and the electronic device generates the shot image in the corresponding pixel signal combination mode. That is, the electronic device does not modify the pixel signal combination method at the instant the capture key is triggered.

In a third aspect, in another possible implementation, the method may further include: when the electronic equipment generates a second preview image in a first pixel signal combination mode, the electronic equipment outputs a preview image frame according to a first rate; and when the electronic equipment generates a third preview image by adopting a second pixel signal combination mode, the electronic equipment outputs a preview image frame according to the first rate.

In a third aspect, in another possible implementation, the method may further include: when the electronic equipment generates a second preview image in a second pixel signal combination mode, the electronic equipment outputs a preview image frame according to a first rate; when the electronic equipment generates a fourth preview image by adopting the first pixel signal combination mode, the electronic equipment outputs the preview image frame according to the first rate.

It can be understood that, in the process of displaying the preview image by the electronic device, the electronic device has a phenomenon of switching the pixel signal combination mode. If the pixel signal combination mode is switched, the speed of the electronic equipment outputting the preview image frame is unchanged before and after the electronic equipment switches the pixel signal combination mode. In this way, the preview image displayed by the electronic equipment can be ensured to be stable.

In a third aspect, in another possible implementation, when the third preview image is generated by using the first pixel signal combination method, the method may specifically include: the electronic equipment outputs a first initial image in a first pixel signal combination mode, and generates a third preview image from the first initial image according to a preset image algorithm, so that the brightness of the third preview image is approximate to that of the second preview image.

Due to the fact that the pixel signal combination mode is switched, the brightness of the third preview image is approximate to that of the second preview image, and therefore the brightness of the preview image displayed by the electronic equipment is kept stable and does not change suddenly. If the brightness of the shooting environment where the electronic equipment is located is greatly changed, the brightness of the preview image displayed by the electronic equipment is gradually improved after the pixel signal combination mode is switched.

In another possible implementation of the third aspect, when generating the fourth preview image by using the second pixel signal combination method, the method includes: and the electronic equipment outputs a second initial image in a second pixel signal combination mode, and generates a fourth preview image from the second initial image according to a preset image algorithm, so that the brightness of the fourth preview image is approximate to that of the second preview image.

In a third aspect, in another possible implementation, the resolution of the first original image corresponds to a third magnification.

In a possible implementation of the third aspect, the resolution of the second initial image is a fourth resolution, and the fourth resolution is greater than the third resolution; after the electronic device outputs the second initial image in the second pixel signal combination mode, before generating a fourth preview image from the second initial image according to a preset image algorithm, the method may further include: the electronic equipment performs cropping processing on the second initial image so that the resolution of the second initial image is the third resolution.

In a third aspect, in another possible implementation, an electronic device generates a captured image by using a first pixel signal combination method, including: the electronic equipment outputs multi-frame image frames in a first signal combination mode, and generates shot images according to the multi-frame image frames based on a first image fusion algorithm. The electronic device generates the captured image by using a second pixel signal combination method, which may specifically include: the electronic equipment outputs a plurality of frames of original image frames in a second signal combination mode, cuts each frame of original image frames to obtain a plurality of frames of cut image frames, and generates a shot image according to the plurality of frames of cut image frames based on a second image fusion algorithm.

In a third aspect, in another possible implementation, the first image fusion algorithm at least includes: one of a multi-frame noise reduction algorithm, a high dynamic range algorithm, a high dynamic super-resolution algorithm and a super-resolution algorithm based on a human face; the second image fusion algorithm comprises at least: one of a multi-frame noise reduction algorithm, a high dynamic range algorithm, a high dynamic super-resolution algorithm and a super-resolution algorithm based on a human face.

In a third aspect, in another possible implementation, if the electronic device includes one or more front cameras, the electronic device implements a shooting function through the one or more front cameras, and the third magnification is 2.0 times; if the electronic equipment comprises one or more rear cameras, the electronic equipment realizes the shooting function through the one or more rear cameras, and the third rate is a rate value of the third rate interval or the fourth rate interval.

In a third aspect, in another possible implementation, the third magnification interval is 3.0-3.4 magnifications; the fourth magnification interval is 7.0 magnification to 50.0 magnification.

Detailed Description

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, "a plurality" means two or more unless otherwise specified.

In order to facilitate understanding of the schemes provided by the embodiments of the present application, some terms related to the embodiments of the present application will be explained below:

first pixel signal combination method (Binning): in the process of shooting an image by the electronic equipment, light reflected by a target object is collected by the camera, so that the reflected light is transmitted to the image sensor. The image sensor comprises a plurality of photosensitive elements, each photosensitive element collects charges as a pixel, and analog merging (Binning) operation is carried out on pixel information. Specifically, Binning can merge n × n pixels into one pixel. For example, Binning can synthesize adjacent 3 × 3 pixels into one pixel, that is, the color of the adjacent 3 × 3 pixels is presented in the form of one pixel.

For ease of understanding, the first pixel signal combination method may be referred to as a "first pixel arrangement method", a "first pixel combination method", a "first image readout mode", and the like.

Exemplarily, as shown in fig. 1A, fig. 1A is a schematic diagram illustrating a process of reading out an image in a Binning manner after the electronic device acquires the image. As shown in fig. 1A (a) which is a schematic diagram of 6 × 6 pixels, adjacent 3 × 3 pixels are synthesized into one pixel. Fig. 1A (b) is a schematic diagram of a pixel read by Binning. For example, 3 × 3 pixels in the 01 region in (a) in fig. 1A are formed into a pixel G in (b) in 1A by Binning; 3 × 3 pixels in the 02 region in (a) in fig. 1A are formed as a pixel B in (B) in 1A; 3 × 3 pixels in the 03 region of (a) in fig. 1A are formed as a pixel R in (b) in fig. 1A; the 3 × 3 pixels in the 04 region of (a) in fig. 1A are shown as the pixel G in (b) in fig. 1A.

Here, taking the example that the output image format is a Bayer (Bayer) format image, the Bayer format image refers to an image including only red, blue, and green (i.e., three primary colors) in the image. For example, a pixel a formed by 3 × 3 pixels in the 01 region is red, a pixel B formed by 3 × 3 pixels in the 02 region is green, a pixel C formed by 3 × 3 pixels in the 03 region is green, and a pixel D formed by 3 × 3 pixels in the 04 region is blue.

Second pixel signal combination mode (Remosaic): when the image is read out in a Remosaic mode, pixels are rearranged into a Bayer pattern image. For example, assuming that a pixel in an image is composed of n × n pixels, n × n pixels can be rearranged in the image using Remosaic. For convenience of understanding, the second pixel signal combination method may also be referred to as a "second pixel arrangement method", a "second pixel combination method", a "second image reading mode", and the like.

Illustratively, as shown in fig. 1B, (a) is a schematic diagram of pixels, each pixel being synthesized by adjacent 3 × 3 pixels. Fig. 1B (B) is an image schematic of a Bayer pattern read out in a Remosaic method. Specifically, in fig. 1B (a), the pixel a is red, the pixels B and C are green, and the pixel D is blue. Each pixel in (a) in fig. 1B is divided into 3 × 3 pixels and rearranged respectively. That is, the readout is performed by using Remosaic method, and the read image is an image in Bayer format shown in fig. 1B (B).

It can be understood that when the zoom factor is increased during the process of shooting the image, the electronic device may affect the definition of the image. In a shooting scene with medium or low brightness, if a Binning mode is adopted to synthesize a plurality of pixels into one pixel, the light sensing performance of the image sensor can be improved, and the signal-to-noise ratio can be increased. In a high-brightness shooting scene, if a Remosaic mode is adopted, one pixel is rearranged into an image with a Bayer format, and the definition of the image can be improved.

In some implementations, during the capturing of the image by the electronic device, the display screen of the electronic device displays the preview image in real time in response to the zoom operation. The preview image is a target object image captured by the electronic device after the zoom operation.

For example, when the electronic device photographs a target object, the electronic device displays a preview image 201 as shown in (a) in fig. 2. At this time, the zoom magnification of the electronic apparatus is "1 ×" (1 time), i.e., no zoom. The electronic apparatus receives a zoom operation, which is a gesture of a user's double fingers sliding outward, as shown in fig. 2 (a). In response to receiving the zoom operation, the electronic device displays a preview interface 202 as shown in fig. 2 (b). At this time, the electronic apparatus displays that the zoom magnification is "3 ×". Wherein the preview image 202 is a portion of the preview image 201 without zoom magnification when the electronic device is responsive to a zoom operation.

Note that, the above process is an example of increasing the zoom factor. Assuming that the zoom operation is a zoom-out magnification, more content may be included in preview image 202 than preview image 201.

Specifically, when the electronic device displays a preview image, the image can be read out by Binning. When the shooting key is triggered, the electronic equipment judges the current shooting brightness, and if the electronic equipment determines that the shooting brightness of the shooting scene is larger than a preset threshold value, the electronic equipment is switched to a Remosaic mode to read out the image. And if the electronic equipment determines that the shooting brightness of the shooting scene is less than or equal to the preset threshold, the electronic equipment reads the image in a Binning mode and displays the shot image.

When the shooting brightness of the shooting scene is greater than the preset threshold value, and the pixel signal combination mode is switched in the electronic device, the electronic device needs to switch the setting of the image sensor (sensor setting). In the switching process, the image sensor needs to stop pixel signal combination firstly, so that the preview image displayed by the electronic equipment is stopped, and after the switching is finished, the electronic equipment can display and display the shot image.

In some embodiments, when the user uses the mobile phone to capture an image, the user may instruct the mobile phone to start the camera application by a touch operation, a key operation, a gesture operation, or a voice operation. After the camera application is started, the mobile phone can automatically enter a shooting mode such as a shooting mode and a video recording mode, and a preview interface is displayed.

Illustratively, as shown in fig. 4 (a), the user may instruct the mobile phone to open the camera application by clicking a "camera" application icon 401, and the mobile phone runs the camera application, displaying a shooting interface as shown in fig. 4 (b). Or, when the mobile phone is in the screen lock state, the user may instruct the mobile phone to start the camera application through a gesture of sliding rightward on the screen of the mobile phone, and the mobile phone may also display the shooting interface shown in fig. 4 (b). Or, the mobile phone is in a screen locking state, the screen locking interface includes a camera application icon, and the user instructs the mobile phone to open the camera application by clicking the camera application icon, so that the mobile phone displays the shooting interface shown in (b) in fig. 4. Or when the mobile phone runs other applications, the application has the authority of calling the camera application. And (4) the user instructs the mobile phone to start the camera application by clicking the corresponding control, and then the mobile phone displays the shooting interface shown in (b) in fig. 4.

The function control comprises: large aperture, portrait, photograph and video, etc. In some implementations, a zoom magnification indication 403 may also be included in the capture interface. Generally, the default zoom factor of the mobile phone is a basic multiple, which is "1 ×". The zoom factor can be understood as the focal length of the current camera, which is equivalent to the zoom/zoom factor of the reference focal length. When the mobile phone displays the preview interface, at least one camera may be in a working state. The reference focal length is usually the focal length of the main camera of the mobile phone.

Illustratively, the mobile phone includes a wide-angle camera, a middle-focus camera and a long-focus camera. Assuming that the relative position of the target object and the mobile phone is unchanged, the focal length of the wide-angle camera is the minimum, the field angle is the maximum, and the size of the target object in the shot image is the minimum. The focal length of the middle-focus camera is larger than that of the wide-angle camera, the field angle is smaller than that of the wide-angle camera, and the size of a target object in a shot image is larger than that of the wide-angle camera. The long-focus camera has the largest focal length and the smallest field angle, and the size of the target object in the shot image is the largest.

The field angle is used for indicating the maximum angle which can be shot by the camera in the process of shooting the target object by the mobile phone. If the target object is in the maximum angle range which can be shot by the camera, the illumination reflected by the target object can be collected by the camera, so that the image of the target object is displayed in the preview image displayed by the mobile phone. If the target object is out of the maximum angle range which can be shot by the camera, the illumination reflected by the target object cannot be collected by the camera, and thus, the image of the target object cannot appear in the preview image displayed by the mobile phone. Generally, the larger the angle of view of a camera, the larger the shooting range when using the camera. The smaller the angle of view of the camera, the smaller the shooting range when using the camera. It is understood that the field angle may also be referred to as a "field of view range," "field of view region," or the like.

It should be noted that, in the process of taking an image, the mobile phone may use any one of the cameras as a main camera, and use the focal length of the main camera as a reference focal length.

For example, when a mobile phone is running a camera application, the mobile phone uses a middle-focus camera as a main camera, the focal length of the main camera is set as a reference focal length, and the zoom magnification is "1 ×". If the mobile phone simultaneously uses the long-focus camera and the middle-focus camera to acquire images, the focal length of the long-focus camera and the focal length multiple of the main camera (namely the middle-focus camera) are used as the zoom magnification of the long-focus camera. Assume that the focal length of the tele camera is 5 times the focal length of the main camera, i.e., the zoom factor of the tele camera is "5 ×". When the mobile phone is capturing an image, the captured image can be digitally zoomed according to the user operation, and thus, the image captured using the telephoto camera can correspond to a zoom magnification of one section, such as "5 x" to "25 x".

For another example, the mobile phone simultaneously uses the wide-angle camera (short-focus camera) and the main camera (i.e. middle-focus camera) to obtain an image, and the focal length of the short-focus camera and the focal length multiple of the main camera can be used as the zoom multiple of the short-focus camera. Assume that the focal length of the short focus camera may be 0.5 times the focal length of the main camera, i.e., the zoom magnification of the short focus camera is "0.5 ×". Based on this, when an image is captured by using a short-focus camera, digital zooming is performed, so that the image captured by using the short-focus camera can correspond to a zoom magnification of one section, such as "0.5 ×" to "1 ×".

In some embodiments, as shown in fig. 5 (a), when the mobile phone runs the camera application to display a shooting interface, the user may reduce the zoom magnification used by the mobile phone by making a gesture of double-finger (or three-finger) pinch on the display screen of the mobile phone; or, the user can make a gesture that two fingers (or three fingers) slide outwards on the display screen of the mobile phone, namely the gesture is opposite to the direction of pinching, so that the distance between the fingers is increased, and the zoom magnification used by the mobile phone is increased.

As shown in fig. 5 (b), the mobile phone includes a scale 501 for indicating the current zoom magnification when displaying the shooting interface. The user can drag an arrow in the scale in the shooting interface to adjust the zoom magnification used by the mobile phone.

In addition, the user can change the zoom magnification of the mobile phone by switching the current shooting mode in the shooting interface. For example, the mobile phone is currently in a photographing mode, the mobile phone can capture an image by using a middle-focus camera, and if the user selects to switch to a portrait mode, the mobile phone is switched to a short-focus camera, and the zoom magnification is increased.

Illustratively, a mobile phone runs a camera application, and the mobile phone reads out an image in a Binning manner, and takes the read-out image as a preview image. The mobile phone receives zoom operation input by a user, and in response to the zoom operation, the mobile phone displays a preview image corresponding to the zoom magnification. Assuming that the zoom factor of the cell phone is "3 x" in response to the zoom operation, the cell phone image sensor setting is as shown in fig. 6. The mobile phone reads out the image in a Binning mode, and the processed image is presented on a display screen as a preview image. The zoom factor is "3 ×", the image pixels read out by the cell phone are 4000 × 3000, i.e., the preview image is 4000 × 3000, and read out in Binning. When a shooting key of the mobile phone is triggered, the mobile phone captures an image and reads the image in a Remosaic mode. As shown in fig. 6, the first switching process of the image sensor: during image capturing, the image sensor of the mobile phone can read out 12000 × 9000 images in a Remosaic manner. Since the mobile phone outputs an image in a scene with a zoom factor of "3 ×", the mobile phone performs cropping (i.e., crop operation) on the image read out in the Remosaic mode, so that the image becomes an image read out in the Remosaic mode with pixels 4000 × 3000. Further, the second switching of the image sensor: an image of pixel 4000 × 3000, read out in Remosaic, can be converted to an image of 4000 × 3000, read out in Binning. Thus, the 4000 × 3000 image can be displayed on the display of the mobile phone and read out by Binning.

In some embodiments, after the mobile phone receives the zoom operation, the mobile phone may monitor the brightness in the current shooting environment in real time during the preview. And adjusting the pixel signal combination mode according to the current zoom multiple and the brightness value in the environment. Take an example in which the mobile phone receives a zoom operation, and the zoom operation instructs the mobile phone to display an image at a zoom magnification of "3 ×".

As shown in fig. 7, the mobile phone currently reads out an image by Binning at the time of preview, taking as an example that the mobile phone reads out an image of 4000 × 3000 by Binning in response to a zoom operation. And if the brightness in the current shooting environment is determined to exceed the preset threshold, the mobile phone modifies the current pixel signal combination mode from Binning to Remosaic. Certainly, the image is read out in a Remosaic manner, and the image needs to be crop to ensure that the image corresponding to the zoom multiple is obtained, that is, the mobile phone obtains the 4000 × 3000 image in a Remosaic + crop manner. And if the brightness in the current shooting environment is determined to be changed, the brightness of the shooting environment is less than the preset threshold value. Thus, the mobile phone can modify the current pixel signal combination mode from Remosaic + crop to Binning.

It should be mentioned that, since the mobile phone can adjust the pixel signal combination mode in real time according to the brightness in the current shooting environment, when the shooting key is triggered, the mobile phone still obtains the shot image according to the corresponding pixel signal combination mode. As shown in fig. 7, when the mobile phone reads a 4000 × 3000 image by Binning and presents the image as a preview image on the display of the mobile phone, the shooting key is triggered, and the mobile phone still reads the image by Binning to generate a 4000 × 3000 shot image. When the mobile phone reads out the 4000 x 3000 image in the mode of Remosaic + crop and displays the image on the display screen of the mobile phone as a preview image, the shooting key is triggered, and the mobile phone still reads out the image in the mode of Remosaic + crop to generate the 4000 x 3000 shooting image.

The brightness in the current shooting environment exceeds the preset threshold, which may indicate that the brightness in the current shooting environment is greater than the preset threshold, or indicate that the brightness in the current shooting environment is greater than or equal to the preset threshold. The brightness in the current shooting environment is less than the preset threshold, which may indicate that the brightness in the current shooting environment is less than or equal to the preset threshold, or that the brightness in the current shooting environment is less than the preset threshold.

It should be noted that the brightness threshold of the mobile phone from the high-brightness environment to the dark-light environment may be a first threshold, that is, the mobile phone determines that the brightness of the environment is less than the first threshold, and the mobile phone switches from the Remosaic + crop mode to the Binning mode to read out the image. The brightness threshold of the mobile phone from the dark light environment to the highlight environment can be a second threshold, namely the mobile phone determines that the ambient brightness exceeds the second threshold, and the mobile phone switches from the Binning mode to the Remosaic + crop mode to read out the image.

For example, the second threshold may be greater than the first threshold. That is, the second threshold is different from the first threshold, and when the mobile phone determines that the brightness of the shooting environment exceeds the second threshold, the mobile phone switches the pixel signal combination mode. And when the mobile phone determines that the brightness of the shooting environment is lower than the second threshold and is less than the first threshold, the mobile phone switches the pixel signal combination mode again. Therefore, the image sensor of the mobile phone can be protected, the pixel signal combination mode (also called ping-pong switching pixel signal combination mode) of the mobile phone is prevented from being adjusted in a reciprocating manner, and the stable operation of the mobile phone photographing system is favorably maintained.

In this embodiment, when the mobile phone switches the sensor setting, the mobile phone may keep the rate of the image sensor outputting the image frames unchanged. For example, the image sensor outputs images at a rate of 30 frames/sec, and the mobile phone may always keep outputting images at a rate of 30 frames/sec regardless of the manner in which the pixel signals are combined or whether the photographing key is activated. In this case, when the sensor setting is performed, the mobile phone reads a 4000 × 3000 image by Binning, and after the switching of the pixel signal combination method is completed, the mobile phone switches to read a 4000 × 3000 image by Remosaic + crop.

It is worth noting that the mobile phone collects the illumination intensity in the current shooting environment in real time, and after the zoom multiple is determined, the pixel signal combination mode of the image sensor is adjusted according to the illumination intensity. That is, the image sensor adopts Binning or Remosaic and the light sensing energy is not different by adopting different pixel signal combination modes. When the image sensor switches the pixel signal combination mode, the mobile phone can adopt a preset image algorithm to ensure that the color reduction degree of the image is high, and the brightness of the previewed image is uniform when the image sensor switches the pixel signal combination mode.

Illustratively, the preset algorithm may be a 3A technique. Among them, the 3A technology is abbreviated as Auto Focus (AF), Auto Exposure (AE), and Auto White Balance (AWB). Specifically, when the image sensor switches the pixel signal combination mode, the maximum image contrast can be realized by using an AF algorithm, an AE algorithm and an AWB algorithm by adopting a 3A technology, the overexposure or underexposure condition of a main shot object is improved, and the chromatic aberration of a picture under different light irradiation is compensated. Therefore, the problem of flickering of the preview image possibly occurring in the process of switching the pixel signal combination mode of the image sensor is solved. By adopting the 3A technology, the brightness of a screen display preview picture is smoother and more natural in the process of combining the switching pixel signals of the image sensor.

It is worth mentioning that when the mobile phone reads out the image in a Remosaic mode, the definition of the output image can be improved. In this way, the mobile phone reads out an image in a Remosaic method, and cuts out the read-out image so that the image becomes an image conforming to the zoom magnification. After the shooting key is triggered in the pixel signal combination mode, the mobile phone obtains an image in a Remosaic + crop mode, can acquire a plurality of frames of images, generates a shot image according to the plurality of frames of images, and displays the shot image on the mobile phone. The image of the multiple frames can improve the signal-to-noise ratio of the shot image, so that the details in the shot image are enhanced, and the shot image has a High-Dynamic Range (HDR) effect.

That is, images of a plurality of frames are captured at different exposure times, and a captured image is obtained from the images of the plurality of frames. The final HDR image (i.e. the shot image) is synthesized by using the detail image corresponding to each exposure time, so that the visual effect in the real environment can be better reflected. For example, an image obtained by a Remosaic + crop mode is a clearer image relative to an image obtained by a Binning mode, and a mobile phone synthesizes three images obtained by continuous exposure shooting into one image, so that the detailed expression of the image can be improved.

Specifically, different sensor setting strategies may be set at different zoom magnifications. After the mobile phone acquires the image, the image can be processed by using different algorithms. After the mobile phone acquires the zooming operation, the front camera and the rear camera in the mobile phone can set different sensor setting strategies and image processing algorithms.

In one possible implementation, the handset includes three rear cameras and two front cameras. As shown in fig. 8 (a), the front camera includes a first front camera 801 and a second front camera 802; as shown in fig. 8 (b), the rear cameras include a first rear camera 803, a second rear camera 804, and a third rear camera 805.

For example, the configuration of the rear three cameras may be: the first rear camera is a main camera (middle focus camera), the specification is 108M (the shooting pixel is 1920 × 1080), and the camera adopts a 3 × 3 quad sensor; the second rear camera is an ultra-wide-angle camera with the specification of 8M (800 ten thousand pixels); the third rear camera is a tele camera, with a 64M (6400 ten thousand pixels) specification, and employs a 2x2 quad sensor, 3.5x tele. Wherein the optical zoom magnification of tele is 3.5 ×. That is, at the 35mm equivalent focal length, the third rear camera focal length is 3.5 times the main-shooting (first rear camera) focal length.

The configuration of the two front cameras may be: the first front camera is a main camera, the specification is 32M, and the camera adopts a 2x2 quad sensor; the second front camera is a wide-angle camera with the specification of 12M.

The preset image processing algorithm in the mobile phone comprises the following steps: multi-frame noise reduction (MFNR), High Dynamic Range (HDR), High Dynamic Super Resolution (HDSR), Face-based super resolution (Face super resolution), and the like.

MFNR: and realizing image noise reduction according to the multi-frame images. Specifically, similar pixel points of a current pixel are searched in a frame of image, and weighted average operation is performed on the pixel points, so that the similar pixels have the same display effect, and image noise is reduced. HDR: when multi-frame image fusion can be realized, the pixel contrast of the generated image is improved, so that the dynamic range of the image is improved. HDSR: and realizing a super-resolution algorithm on the basis of high dynamic range fusion. FACSERR: the super-resolution algorithm based on the human face can enable the human face on the image to be clearer by enhancing the human face boundary, so that the definition of the whole image is improved.

When the mobile phone adopts the rear camera to collect images, the zooming multiples are different, and then the mobile phone can adopt different image algorithms and image sensor settings. Referring to table 1 below, different zoom scenes of the image are acquired by using the rear camera for the mobile phone.

Table 1: zoom range and image processing algorithm corresponding relation for collecting image by adopting rear camera

When the mobile phone adopts the front camera to collect images, the zooming multiples are different, and then the mobile phone can adopt different image algorithms and image sensor settings. Referring to table 2 below, different zoom scenes of the image are acquired by using the front camera for the mobile phone.

Table 2: corresponding relation between zooming range for acquiring image by adopting front-facing camera and image processing algorithm

An embodiment of the present application further provides a shooting method, please refer to fig. 9, where the method may include:

here, taking the zoom magnification of the electronic device in the preset magnification range as an example (that is, the zoom magnification is the second magnification and is smaller than the preset magnification), the shooting method provided in the embodiment of the present application is described. For example, the zoom magnification is less than 3 ×. The electronic equipment realizes shooting functions through an ISP (internet service provider), a camera, a video encoder, a GPU (graphic processing unit), a display screen, a processor and the like. If the electronic equipment adopts the front camera to realize the shooting function, the zooming range is 0.8-1.9 x. If the electronic equipment adopts the rear camera to realize the shooting function, the zooming range comprises 1.0-2.9x and 3.5 x-6.9 x.

Step 901: the electronic device starts the camera.

Step 902: the electronic equipment displays a first preview image, and the zoom magnification corresponding to the first preview image is a first magnification.

Illustratively, the electronic device starts up the camera, and the electronic device displays the preview image corresponding to the zoom magnification of 1 ×.

Step 903: the electronic equipment receives a first operation input by a user, and the first operation instructs the electronic equipment to adjust the zoom magnification of the camera to a second magnification.

Wherein the second magnification is different from the first magnification. The first operation may include instructing the electronic device to increase a zoom magnification of the camera or to decrease the zoom magnification of the camera.

For example, the first operation may be instructing the electronic device to increase a zoom magnification of the camera to a second magnification; alternatively, the first operation may be instructing the electronic device to zoom out the zoom magnification of the camera to the second magnification.

Step 904: and responding to the first operation, the electronic equipment generates a second preview image in a first pixel signal combination mode, and displays the second preview image.

And the zooming magnification corresponding to the second preview image is a second magnification.

Step 905: and determining the brightness of the shooting environment in which the electronic equipment is positioned in response to the shooting key being triggered.

Specifically, the electronic device may recognize the brightness of the shooting environment in which the electronic device is currently located through a plurality of sensors (e.g., an ambient light sensor, a light sensor, etc.) and the display screen.

Step 906: if the brightness is larger than a first preset threshold value, the electronic equipment generates a shot image in a second pixel signal combination mode; and if the brightness is less than or equal to a first preset threshold value, the electronic equipment generates a shot image in a first pixel signal combination mode.

The electronic equipment determines the brightness of the current shooting environment at the moment when the shooting key is triggered, and adjusts the pixel signal combination mode of the image sensor according to the brightness.

In some implementations, when the electronic device generates the captured image by using the second pixel signal combination method, the electronic device needs to switch from the first pixel signal combination method to the second pixel signal combination method when capturing the image. The electronic device stops outputting the image frame in the first pixel signal combination mode, and therefore the electronic device stops displaying the preview image. At this time, the electronic device sets a mode of switching from the first pixel signal combination mode to the geothermal pixel signal combination mode, and when the image sensor completes the switching, the electronic device generates a shot image by adopting a second pixel signal combination mode.

After the electronic device generates the shot image, if the electronic device is still in the shooting state, the electronic device may switch the second pixel signal combination mode to the first pixel signal combination mode. The electronic equipment continues to output the image frames in the first pixel signal combination mode and continues to provide preview images for the electronic equipment.

It should be noted that, when the captured image is generated by using the second pixel signal combination method, the electronic device needs to crop (crop) the image output by the image sensor, and reference may be made to the method for generating an image by using the second pixel signal combination method in the foregoing embodiment specifically, and details are not repeated herein to avoid redundancy.

An embodiment of the present application further provides a shooting method, please refer to fig. 10, where the method may include:

the photographing method provided by the embodiment of the present application is described herein by taking an example that the zoom magnification of the electronic device is within a preset magnification range (i.e., the zoom magnification is a third magnification that is greater than or equal to a preset magnification). For example, the zoom magnification is less than 3 ×. As in tables 1 and 2, the photographing function is realized by the rear camera, and the zoom ranges include 3.0x-3.4x and 7.0 x-50.0 x; the shooting function is realized by the front camera, and the third rate can be 2.0 x.

Step 1001: the electronic device starts the camera.

Step 1002: the electronic equipment displays a first preview image, and the zoom magnification corresponding to the first preview image is a first magnification.

Step 1003: the electronic equipment receives a first operation, and the first operation instructs the electronic equipment to adjust the zoom magnification to a third magnification.

Wherein the first magnification is different from the second magnification, and the first operation may include instructing the electronic device to increase a zoom magnification of the camera or to decrease the zoom magnification of the camera.

The steps 1001 to 1003 are the same as the steps 901 to 903, and the specific implementation may refer to the related description, which is not described herein again.

Step 1004: the electronic equipment determines the brightness of the shooting environment and judges whether the brightness is larger than a first preset threshold value. If the brightness is less than or equal to the first preset threshold, executing step 1005-step 1006; if the brightness is larger than the first preset threshold, steps 1007-1008 are executed.

The manner of determining the brightness of the shooting environment has been described above, and is not described herein again.

Step 1005: and generating a second preview image by adopting a first pixel signal combination mode, wherein the zoom magnification corresponding to the second preview image is a third magnification.

Step 1006: in response to the shooting key being triggered, the electronic device generates a shot image in a first pixel signal combination mode.

Step 1007: and generating a second preview image by adopting a second pixel signal combination mode, wherein the zoom magnification corresponding to the second preview image is a third magnification.

Step 1008: and in response to the shooting key being triggered, the electronic equipment generates a shot image in a second pixel signal combination mode.

It can be understood that in the method, when the electronic device generates the second preview image by adopting the first pixel signal combination mode, the shooting key is triggered, and the electronic device generates the shot image by adopting the first pixel signal combination mode. When the electronic equipment generates a second preview image by adopting a second pixel signal combination mode, the shooting key is triggered, and the electronic equipment generates a shot image by adopting the second pixel signal combination mode.

It is worth mentioning that in the above method, the electronic device identifies the brightness of the current shooting environment in real time. If the brightness changes, the electronic device can also adjust the pixel signal combination mode in real time. The real-time is the brightness of the shooting environment where the electronic equipment identifies the current shooting environment once every 5s, 10s or 15 s.

And setting a pixel signal combination mode of the image sensor according to the zoom magnification and the shooting brightness of the current environment.

The electronic device may refer to the zoom magnifications in tables 1 and 2 described above, and the pixel signal combination manner of the image sensor at the zoom magnifications. Particularly, for example, when the mobile phone acquires an image by using a rear camera, when the zoom magnification is 3.3 × -3.4 ×, or the zoom magnification is 7.0 x-50.0 x, the mobile phone may adjust the image output mode of the image sensor according to the brightness of the current shooting environment. And if the shooting environment brightness is a highlight scene, reading out the image in a remoiac + crop mode and generating a shot image. And if the shooting environment brightness is a scene with medium and low brightness, reading out the image by adopting a Binning mode.

In addition, the electronic equipment adjusts the pixel signal combination mode in real time according to the brightness of the current shooting environment. In order to avoid the influence on the shooting of the electronic equipment caused by frequent switching, when the electronic equipment is larger than a first preset threshold value, the electronic equipment is switched to a second pixel signal combination mode to output an image frame. When the electronic device is smaller than a second preset threshold, the electronic device switches from the second pixel signal combination mode to the first pixel signal combination mode. And the second preset threshold is smaller than the first preset threshold.

It can be understood that the electronic device displays the second preview image with better definition. Therefore, the electronic equipment can improve the definition of the zoom image during zooming shooting, reduce the signal to noise ratio of the image and improve the image quality.

The method provided by the embodiment of the present application is described above by taking the electronic device as a mobile phone as an example, and when the electronic device is another device, the method can also be adopted. And will not be described in detail herein.
