Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.
It is understood that the execution subject of the embodiment of the present application may be an electronic device such as a smart phone or a tablet computer.
Referring to fig. 1, fig. 1 is a schematic flow chart of an imaging method according to an embodiment of the present disclosure. The imaging method can be applied to electronic equipment, and the electronic equipment can comprise a first long-focus camera module, a wide-angle camera module and a plurality of second long-focus camera modules, wherein the second long-focus camera modules are movable camera modules. The flow of the imaging method may include:
101. and acquiring an ambient light brightness value.
102. According to the ambient light brightness value, the target camera module is determined from the first long-focus camera module and the wide-angle camera module, and the second long-focus camera modules are driven to move, so that the second long-focus camera modules are overlapped with the shooting area of the target camera module.
At present, users usually use electronic devices with camera modules to capture images, and can record things around and scenes seen through the electronic devices anytime and anywhere. However, due to the hardware defect of the camera module, the middle area of the image shot by the camera module is often clearer, and the edge area is relatively blurred, so that the imaging quality of the whole image is poor.
In this embodiment, for example, after a shooting application (e.g., a camera application) on the electronic device is started, the electronic device may acquire an ambient light brightness value, and determine the target camera module from the first tele camera module and the wide camera module according to the ambient light brightness value.
After determining the target camera module, the electronic equipment can drive a plurality of second long-focus camera modules to move so that the shooting areas of the second long-focus camera modules and the target camera module are overlapped.
It should be noted that, for example, the electronic device has 4 second tele camera modules. The electronic equipment comprises four second long-focus camera modules, namely a long-focus camera module A, a long-focus camera module B, a long-focus camera module C and a long-focus camera module D. When the electronic equipment drives the four second long-focus camera modules to move and move, the axis of each second long-focus camera module inclines towards the axis of the target camera module and intersects with the axis of the target camera module, so that the shooting area a of the long-focus camera module A corresponds to the upper left corner of the shooting area of the target camera module, the shooting area B of the long-focus camera module B corresponds to the upper right corner of the shooting area of the target camera module, the shooting area C of the long-focus camera module C corresponds to the lower left corner of the shooting area of the target camera module, and the shooting area D of the long-focus camera module D corresponds to the lower right corner of the shooting area of the target camera module. Thus, the shooting area of each second tele camera module overlaps with the edge portion of the shooting area of the target camera module, and the overlapping shooting area between any two second tele camera modules (i.e., the overlapping area between the shooting areas of the two second tele camera modules) overlaps with the middle portion of the shooting area of the target camera module.
For example, as shown in fig. 2, the electronic apparatus includes a first tele camera module 10 and a wide camera module 20. Taking the first long-focus camera module 10 determined as the target camera module as an example, when the electronic device drives the four second long-focus camera modules to move and the movement is completed, the four second long-focus camera modules are located around the first long-focus camera module 10. The axis of each second long-focus camera module inclines towards the axis of the first long-focus camera module and is intersected, so that the shooting area a of the long-focus camera module A corresponds to the upper left corner of the shooting area of the first long-focus camera module, the shooting area B of the long-focus camera module B corresponds to the upper right corner of the shooting area of the first long-focus camera module, the shooting area C of the long-focus camera module C corresponds to the lower left corner of the shooting area of the first long-focus camera module, and the shooting area D of the long-focus camera module D corresponds to the lower right corner of the shooting area of the first long-focus camera module. Thus, the shooting area of each second tele camera module overlaps with the edge portion of the shooting area of the first tele camera module, and the overlapping shooting area between any two second tele camera modules (i.e., the overlapping area between the shooting areas of the two second tele camera modules) overlaps with the middle portion of the shooting area of the first tele camera module.
In one embodiment, the first tele camera module may be a standard type camera module, or a camera module with a field angle of about 45 degrees, and the second tele camera module may have a field angle of less than 40 degrees.
For another example, as shown in fig. 3, after the wide camera module 20 is determined as the target camera module, the electronic device drives four second tele camera modules to move upwards from the positions in fig. 2 and the four second tele camera modules are located around the wide camera module 20 after the movement is completed. The axis of each second long-focus camera module inclines towards the axis of the wide-angle camera module and intersects, so that the shooting area a of the long-focus camera module A corresponds to the upper left corner of the shooting area of the wide-angle camera module, the shooting area B of the long-focus camera module B corresponds to the upper right corner of the shooting area of the wide-angle camera module, the shooting area C of the long-focus camera module C corresponds to the lower left corner of the shooting area of the wide-angle camera module, and the shooting area D of the long-focus camera module D corresponds to the lower right corner of the shooting area of the wide-angle camera module. Thus, the shooting area of each second tele camera module overlaps with the edge portion of the shooting area of the wide camera module, and the overlapping shooting area between any two second tele camera modules (i.e., the overlapping area between the two second tele camera module shooting areas) overlaps with the middle portion of the shooting area of the wide camera module.
The positional relationship of the telephoto camera module A, B, C, D and the photographing region of the object camera module may be as shown in fig. 4.
In one embodiment, for example, a guide rail and a driving device may be provided in the electronic device, each second tele camera module may be provided on the guide rail, and the driving device is electrically connected to each second tele camera module for driving the second tele camera module to move on the guide rail.
103. An image capturing request of a subject to be captured is received.
For example, after determining that the target camera module and driving the plurality of second tele camera modules move to the target position where the shooting areas of the plurality of second tele camera modules and the target camera module can overlap, the electronic device may receive an image shooting request of an object to be shot.
For example, the image capturing request may be directly input by the user for instructing the electronic apparatus to capture the subject to be captured. When an object to be photographed, namely, an electronic device receives an input image photographing request, objects aimed by the camera module include, but are not limited to, people, objects, scenes and the like.
For example, after operating the electronic device to start a shooting application (such as a system application "camera" of the electronic device), and moving the electronic device so that a camera module of the electronic device is aligned with an object to be shot, a user may input an image shooting request to the electronic device by clicking a "shooting" key (which may be a virtual key) provided on a "camera" interface.
For another example, after a user operates the electronic device to start a shooting application and moves the electronic device so that a camera module of the electronic device is aligned with an object to be shot, the user can send a voice command "take a picture" to the electronic device, thereby inputting an image shooting request to the electronic device. In addition, the electronic device may also send an image capturing request to the electronic device in an instruction form such as a gesture, which is not limited in this embodiment.
104. The object to be shot is shot through the target camera module, or the object to be shot is shot through the first long-focus camera module and the wide-angle camera module, and a base image is obtained.
For example, after receiving an image capturing request of an object to be captured, the electronic device may capture the object to be captured through the target image capturing module, or capture the object to be captured through the first tele image capturing module and the wide image capturing module, so as to obtain the base image.
That is, after receiving an image capturing request of an object to be captured, the electronic device may capture the object to be captured only by one image capturing module, which is the target image capturing module, so as to obtain a base image. Or after receiving an image shooting request of the object to be shot, the electronic device may shoot the object to be shot through two camera modules, namely, the first telephoto camera module and the wide-angle camera module (one of which is the target camera module), so as to obtain the base image.
105. And shooting the object to be shot through the second long-focus camera modules to obtain a plurality of target images.
For example, after receiving an image shooting request of an object to be shot, the electronic device may shoot the object to be shot through the plurality of second tele image capturing modules, so as to obtain a plurality of images, that is, a plurality of target images.
It should be noted that, when the second telephoto imaging modules are used to capture an object to be captured, the second telephoto imaging module and the target imaging module (or the first telephoto imaging module and the wide-angle imaging module) use the same parameters (such as contrast, brightness, exposure time, etc.) to capture images. Therefore, the shooting area of the second tele camera module is a local part of the shooting area of the target camera module (or the first tele camera module and the wide camera module), and the images shot by the second tele camera module and the target camera module have the same effect.
For example, the electronic device includes four second tele camera modules, namely a tele camera module A, a tele camera module B, a tele camera module C and a tele camera module D, and the shooting areas of the four second tele camera modules respectively correspond to the upper left corner, the upper right corner, the lower left corner and the lower right corner of the shooting area of the target camera module, as shown in fig. 5, for example, the image content of the image P1 captured by the telephoto camera module a corresponds to the image content of the upper left corner of the base image, the image content of the image P2 captured by the telephoto camera module B corresponds to the image content of the upper right corner of the base image, the image content of the image P3 captured by the telephoto camera module C corresponds to the image content of the lower left corner of the base image, and the image content of the image P4 captured by the telephoto camera module D corresponds to the image content of the lower right corner of the base image. In this way, the image content captured by the different second tele camera modules covers different positions of the edge region in the base image.
It should be noted that, in the embodiment of the present application, the execution order of 104 and 105 is not specifically limited, and may be to execute 105 after execution is completed 104, execute 104 after execution is completed 105, execute 104 and 105 at the same time, and the like.
106. Image synthesis processing is performed on the base image and the plurality of target images, and an image obtained by the synthesis is used to respond to an image capturing request.
For example, after capturing a base image and a plurality of target images, the electronic device may perform image synthesis processing on the base image and the plurality of target images to obtain corresponding synthesized images, and respond to an image capturing request with the synthesized images. For example, the synthesized image is determined as the imaged image corresponding to the image capturing request.
For example, after capturing the base image and the plurality of target images, the electronic device may align the captured plurality of target images with the base image. Based on the aligned base image and target image, the electronic device may calculate an average pixel value of each pixel point overlapped for an overlapped portion of the base image and the target image. For example, the electronic device obtains the base image through the object camera module, and obtains four object images through the four second tele camera modules. Referring to fig. 6, the overlapping area where each target image and the base image overlap simultaneously is located in the central area of the base image, so that for the overlapping area shown in fig. 6, the pixel values of the pixel point at a certain position W in the five images (i.e., the base image and the four target images) are 108, 109, 110, 112, and 111, respectively, and then the electronic device can calculate that the average pixel value of the pixel point at the position is 110.
Then, the electronic device can obtain a composite image according to the average pixel values obtained by the corresponding position pixel points in the base image. For example, the electronic device may adjust the pixel value of each pixel point of the base image to each average pixel value obtained by calculation, so as to obtain a composite image. For example, for a pixel at position W, the electronic device may adjust its pixel value from 108 to 110. And adjusting the pixel value of the pixel in the base image to obtain a composite image.
For another example, the electronic device may regenerate a new image, i.e., a composite image, according to the average pixel value of each position obtained through calculation.
In the embodiment of the present application, after image synthesis processing is performed on a plurality of captured target images and a base image, an electronic device sets a synthesized image as an imaging image of an image capturing request. At this point, the electronic device completes one complete photographing operation corresponding to the received image photographing request.
With continued reference to fig. 6, fig. 6 thus illustrates the change in sharpness of the base image to the resultant image. Wherein, the X-axis represents the position change from the edge area to the central area of the image and then from the central area to the edge area, and the Y-axis represents the definition of the image. As can be seen from the figure, in the base image, the definition of the central region is the highest, and gradually decreases and changes more sharply as the central region diffuses to the edge region. In the synthesized image, the definition of the central region is the highest, and compared with the base image, the definition of the edge region of the synthesized image is integrally improved, and along with the diffusion from the central region to the edge region, although the definition is gradually reduced, the change is smoother, that is, the definitions of the central region and the edge region of the synthesized image are higher, so that the integral image quality of the synthesized image is improved.
Referring to fig. 7, fig. 7 is another schematic flow chart of an imaging method according to an embodiment of the present disclosure. The imaging method can be applied to electronic equipment, and the electronic equipment can comprise a first long-focus camera module, a wide-angle camera module and a plurality of second long-focus camera modules, wherein the second long-focus camera modules are movable camera modules. The electronic device also includes a light sensor. The flow of the imaging method may include:
201. the electronic equipment acquires the ambient light brightness value through the light sensor.
For example, after a shooting-type application (e.g., a camera application) on the electronic device is started, the electronic device may obtain the ambient light brightness value through its light sensor.
After acquiring the ambient light brightness value, the electronic device may detect whether the ambient light brightness value is greater than or equal to a preset threshold.
In one embodiment, the light-sensitive sensor is a sensor for detecting ambient light levels. The photo sensor 30 may be disposed between the first tele camera module and the wide camera module, as shown in fig. 8.
202. If the ambient light brightness value is greater than or equal to the preset threshold value, the electronic equipment determines the first long-focus camera module as a target camera module; and if the ambient light brightness value is smaller than the preset threshold value, the electronic equipment determines the wide-angle camera module as a target camera module.
For example, if it is detected that the ambient light brightness value is greater than or equal to the preset threshold, it may be determined that the current shooting ambient light is sufficient. In this case, the electronic apparatus may determine the first tele camera module as the target camera module.
If the detected ambient light brightness value is smaller than the preset threshold value, the current shooting ambient light is considered to be insufficient. In this case, the electronic apparatus may determine the wide-angle camera module as the target camera module. It should be noted that, in this embodiment, when light is not enough, the wide-angle lens module is determined as the target camera module, so that the brightness can be better ensured, and the image quality is improved.
203. The electronic equipment drives the second long-focus camera modules to move, so that the second long-focus camera modules are overlapped with the shooting areas of the target camera module.
For example, after determining the target camera module, the electronic device can drive the plurality of second long-focus camera modules to move, so that the shooting areas of the plurality of second long-focus camera modules and the target camera module are overlapped.
Take an example in which the electronic device has 4 second tele camera modules. The electronic equipment comprises four second long-focus camera modules, namely a long-focus camera module A, a long-focus camera module B, a long-focus camera module C and a long-focus camera module D. When the electronic equipment drives the four second long-focus camera modules to move and move, the axis of each second long-focus camera module inclines towards the axis of the target camera module and intersects with the axis of the target camera module, so that the shooting area a of the long-focus camera module A corresponds to the upper left corner of the shooting area of the target camera module, the shooting area B of the long-focus camera module B corresponds to the upper right corner of the shooting area of the target camera module, the shooting area C of the long-focus camera module C corresponds to the lower left corner of the shooting area of the target camera module, and the shooting area D of the long-focus camera module D corresponds to the lower right corner of the shooting area of the target camera module. Thus, the shooting area of each second tele camera module overlaps with the edge portion of the shooting area of the target camera module, and the overlapping shooting area between any two second tele camera modules (i.e., the overlapping area between the shooting areas of the two second tele camera modules) overlaps with the middle portion of the shooting area of the target camera module.
204. The electronic device receives an image capturing request of an object to be captured.
For example, after determining that the target camera module and driving the plurality of second tele camera modules move to the target position where the shooting areas of the plurality of second tele camera modules and the target camera module can overlap, the electronic device may receive an image shooting request of an object to be shot.
205. The electronic equipment shoots the object to be shot through the first long-focus camera module to obtain a first image, and shoots the object to be shot through the wide-angle camera module to obtain a second image.
206. The electronic device synthesizes the first image and the second image to obtain a base image.
For example, 205 and 206 may include:
after receiving an image shooting request of an object to be shot, the electronic equipment can shoot the object to be shot through the first tele camera module to obtain a first image, and shoot the object to be shot through the wide camera module to obtain a second image. The electronic device may then synthesize the first image and the second image to obtain a base image.
For example, when the electronic apparatus synthesizes the first image and the second image, the electronic apparatus may synthesize the first image and the second image by setting the image captured by the target image capture module as a reference frame for image synthesis. For example, if the first telephoto imaging module is determined as the target imaging module, the first image may be set as a reference frame for image synthesis when the first image and the second image are synthesized. In another example, if the wide-angle camera module is determined as the target camera module, the second image may be set as a reference frame for image synthesis when the first image and the second image are synthesized.
For example, if the first image is determined as a reference frame image, the electronic device may perform brightness alignment, position alignment, and the like on the second image and the first image with reference to the first image when the electronic device synthesizes the first image and the second image, and after the brightness alignment, the electronic device may fuse the first image and the second image according to an image fusion algorithm to obtain a synthesized image, thereby obtaining the base image.
207. The electronic equipment shoots the object to be shot through the second long-focus camera modules to obtain a plurality of target images.
For example, after receiving an image shooting request of an object to be shot, the electronic device may shoot the object to be shot through the plurality of second tele image capturing modules, so as to obtain a plurality of images, that is, a plurality of target images.
It should be noted that, when the second telephoto imaging modules are used to capture an object to be captured, the second telephoto imaging module and the target imaging module (or the first telephoto imaging module and the wide-angle imaging module) use the same parameters (such as contrast, brightness, exposure time, etc.) to capture images. Therefore, the shooting area of the second tele camera module is a local part of the shooting area of the target camera module (or the first tele camera module and the wide camera module), and the images shot by the second tele camera module and the target camera module have the same effect.
208. The electronic device performs image synthesis processing on the base image and the plurality of target images, and responds to an image capturing request with the synthesized image.
For example, after capturing a base image and a plurality of target images, the electronic device may perform image synthesis processing on the base image and the plurality of target images to obtain corresponding synthesized images, and respond to an image capturing request with the synthesized images. For example, the synthesized image is determined as the imaged image corresponding to the image capturing request.
In one embodiment, after the target camera module is determined, the electronic device may also acquire the base image only through the target camera module. For example, the electronic device may perform the image flow:
the electronic equipment continuously shoots the object to be shot for multiple times through the target shooting module to obtain multiple third images;
and the electronic equipment performs image synthesis processing on the plurality of third images to obtain a base image.
For example, the electronic device may perform two or three or four times of shooting on the object to be shot through the target shooting module, so as to obtain a plurality of third images. Thereafter, the electronic device may subject the plurality of third images to image synthesis processing such as multi-frame noise reduction, thereby obtaining a base image.
For example, when the electronic device only selects the target camera module to shoot the object to be shot to obtain the base image and the computing power of the electronic device is strong, the electronic device can shoot the object to be shot twice or three times or four times continuously through the target camera module to obtain a plurality of third images. Thereafter, the electronic device may subject the plurality of third images to image synthesis processing such as multi-frame noise reduction, thereby obtaining a base image.
It is understood that, since the shooting time interval is short, the plurality of third images may be regarded as images shot in the same scene, and the contents of the images are the same.
When the electronic device performs image synthesis processing on the plurality of third images, the plurality of third images are aligned first, then an average pixel value of each pixel point overlapped by the aligned plurality of third images is calculated, finally a synthesized image of the plurality of third images is obtained according to each average pixel value obtained by calculation, and the synthesized image is set as a base image.
Compared with the mode that the image shot by the target camera module is directly set as the base image, the base image with higher definition can be obtained in the embodiment of the application, and the finally obtained imaging image also has higher definition.
In another embodiment, after determining the target camera module, the electronic device may obtain a value of a preset parameter, where the value of the preset parameter is used to indicate a computing capability of the electronic device, for example, the preset parameter is a remaining operating memory capacity. If the value of the preset parameter is smaller than the preset value, the computing capability of the electronic equipment is considered to be weak, and at the moment, the electronic equipment can determine that the object to be shot is shot only once through the target camera module, so that the base image is obtained.
In one embodiment, after receiving the image capturing request of the object to be captured, the present embodiment may further include the following process:
the electronic device detects whether it is currently in a jittered state.
Then, electronic equipment carries out to treat through the target module of making a video recording and shoots the object, perhaps treats through first long focus module of making a video recording and wide angle module of making a video recording and shoots the object, when obtaining the basement image, can carry out: if the electronic equipment is not in the shaking state, the electronic equipment shoots the object to be shot through the target camera module, or shoots the object to be shot through the first long-focus camera module and the wide-angle camera module to obtain the base image.
For example, according to the description in the above embodiments, the images captured by different camera modules are finally combined to obtain the imaged image, and if the electronic device is in a shake state during the shooting process, the content of the images captured by different camera modules is obviously different, which affects the combining effect of the imaged images.
Therefore, in the embodiment of the present application, after receiving the input image capturing request, the electronic device may first determine whether itself is currently in a shake state. The electronic device may determine the jitter state in a plurality of different manners, for example, the electronic device may determine whether the current speeds in all directions are greater than a preset speed, if so, determine that the electronic device is in the jitter state, and if not, determine that the electronic device is not in the jitter state (or in a stable state); for another example, the electronic device may determine whether the current displacement in each direction is greater than a preset displacement, if so, determine that the electronic device is in a shaking state, and if not, determine that the electronic device is not in the shaking state. In addition, the judgments of the jitter states may be performed in a manner not listed in the embodiments of the present application, which is not specifically limited by the embodiments of the present application.
When the electronic equipment is judged not to be in the shaking state, the electronic equipment can shoot the object to be shot through the target camera module according to the image shooting request, or shoot the object to be shot through the first long-focus camera module and the wide-angle camera module, so that the base image is obtained.
In one embodiment, when the electronic device performs shooting on the object to be shot through the target camera module or shooting on the object to be shot through the first tele camera module and the wide camera module if the electronic device is not in a shake state currently, and a base image is obtained, the following processes may be performed:
if the current state is not in the shaking state, the electronic equipment detects whether the object to be shot is in a static state;
if the object to be shot is in a static state, the electronic equipment shoots the object to be shot through the target camera module, or shoots the object to be shot through the first long-focus camera module and the wide-angle camera module to obtain a base image.
For example, according to the above description, it can be understood by those skilled in the art that, in the case that the electronic device is not in a shake state, if the object to be photographed is not in a static state (for example, the object to be photographed includes a moving object), the image content of the image captured by the electronic device through the camera module may also have a large difference.
Therefore, in this embodiment of the application, when the electronic device determines that the electronic device is not in the shake state, the electronic device does not immediately shoot the object to be shot through the camera module, but further detects whether the object to be shot is in the still state, and if it is detected that the object to be shot is in the still state, the electronic device shoots the object to be shot through the target camera module according to the image shooting request, or shoots the object to be shot through the first tele camera module and the wide camera module to obtain the base image.
In the present application, a person skilled in the art can select an appropriate manner to determine whether the object to be photographed is in the static state according to actual needs, which is not specifically limited in the present application, for example, an optical flow method, a residual error method, or the like can be used to determine whether the object to be photographed is in the static state.
