Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
The existing intelligent mobile terminal equipment, such as a mobile phone, a tablet personal computer and the like, is generally configured with two camera components, such as a main camera and a telephoto camera; alternatively, the electronic device is also configured with three, four, or five camera assemblies. Due to hardware limitations, optical zoom is typically employed between cameras. In taking pictures or videos, it is usually the case that a single camera module works alone, for example, the main camera works alone or the telephoto camera works alone. When a user operates to trigger a zooming instruction and reaches a zooming multiple critical point, the working states of the long-focus camera and the main shooting lens are exchanged; for example, when the close shot is switched to the long shot, the telephoto camera is changed from the suspended state to the ready state, the current parameters of the telephoto camera are set according to the focal length information of the main camera lens, and the telephoto lens is replaced to collect images and output the images to the preview interface. When the main camera is switched to the long-focus camera, only the long-focus camera is pre-focused, the switching process can be briefly blurred, the zooming process is not smooth enough, the display image in the preview interface can be suddenly changed, the image quality change is large, the display effect is poor, and the user experience is influenced.
In view of the above-described drawbacks and deficiencies of the prior art, an image processing method is provided in the present exemplary embodiment. Referring to fig. 1, the image processing method described above may include the steps of:
s11, acquiring a current focusing parameter corresponding to the first camera shooting assembly, and identifying a numerical range of the current focusing parameter;
s12, when the current focusing parameter is identified to be in a first transformation range, activating a second camera shooting assembly corresponding to the first transformation range;
and S13, acquiring the current image acquired by the first camera assembly, carrying out super-sampling processing on the current image to generate a replacement image, and displaying the replacement image.
In the image processing method provided by this exemplary embodiment, on one hand, the current focusing parameter of the camera shooting assembly is judged in real time, and when the current focusing parameter is within the first conversion range, the second camera shooting assembly corresponding to the first conversion range is activated, and the second camera shooting assembly starts to acquire an image according to the current focusing parameter, so that the two camera shooting assemblies can smoothly switch the preview interfaces during switching, and no blur occurs. On the other hand, the current image collected by the first camera shooting assembly is subjected to super-sampling processing to obtain the replacement image, so that the replacement image subjected to super-sampling processing is displayed in a preset interface, the problem that the image quality of the preview image is reduced due to focal length conversion is avoided, and the image display effect is improved.
Hereinafter, each step of the image processing method in the present exemplary embodiment will be described in more detail with reference to the drawings and examples.
Step S11, acquiring a current focusing parameter corresponding to the first camera module, and identifying a value range of the current focusing parameter.
In the present exemplary embodiment, when a user takes a picture or a video using a camera application in the electronic device, the current focusing parameters of the camera assembly can be acquired in real time in a preview state. For example, the electronic device is configured with at least two camera assemblies, such as: the first camera shooting component is a main camera with higher pixel configuration, the second camera shooting component is a wide-angle camera, the third camera shooting component is a super wide-angle camera, and the fourth camera shooting component is a macro camera and the like.
If the current preview interface is the current image acquired by the first camera shooting assembly on the current scene, the current focusing parameters can be read in real time. When the user operates the variable focal length in the preview interface, the numerical range of the current focusing parameter can be determined in real time. For example, the digital zoom range of the first camera assembly is 1 to 5 times; the digital zoom range of the second camera shooting component is 5 times to 10 times; the digital zoom range of the third camera assembly is 10-20 times. In addition, the transformation range among all the camera modules can be configured in advance; for example, the first transformation range corresponds to the first camera shooting assembly and the second camera shooting assembly, and the first transformation range is 4 times to 6 times; the second transformation range corresponds to the second camera shooting assembly and the third camera shooting assembly, and is 8.5-11 times; and so on. The specific conversion range may be set according to the camera module actually mounted on the electronic device, and this disclosure is not particularly limited thereto.
And step S12, when it is identified that the current focusing parameter is within a first transformation range, activating a second camera module corresponding to the first transformation range.
In this exemplary embodiment, when the electronic device initially starts only the first camera shooting assembly, after recognizing that the current focusing parameter is within the first transformation range, the second camera shooting assembly corresponding to the first transformation range may be activated, and the second camera shooting assembly starts to capture the current image corresponding to the current scene.
For example, pipeline may be configured for the first camera component and the second camera component at the hardware abstraction layer; and configuring a surface view for the first camera shooting assembly and the second camera shooting assembly respectively at the application layer to acquire corresponding preview data. And each camera shooting assembly respectively collects images, and transmits the images to corresponding faceview by using the pipeline corresponding to each camera shooting assembly, so that multi-path preview is realized. And determining which image pickup assembly corresponding preview view is displayed according to the current zoom multiple. For example, in the above-described embodiment, only the preview view of the first camera assembly is currently displayed, and although the second camera assembly is turned on, the image captured by the second camera assembly is not currently displayed in the preview view.
And step S13, acquiring the current image acquired by the first camera assembly, performing super-sampling processing on the current image to generate a replacement image, and displaying the replacement image.
In this exemplary embodiment, when the second camera shooting assembly is started, the current image collected by the first camera shooting assembly may be subjected to super-sampling processing, so as to generate a substitute image with a higher resolution after the super-sampling processing, and display the substitute image in the preview view. For example, the current image shown in fig. 4 is subjected to super sampling processing to generate a replacement image shown in fig. 5. Therefore, when the zoom critical point between the first camera shooting assembly and the second camera shooting assembly is close to, the image in the preview interface can have higher image quality, the change difference of the image when the first camera shooting assembly is switched to the second camera shooting assembly is reduced, so that the image collected by the second camera shooting assembly is replaced by the image after supersampling in a certain focal length conversion range when the first camera shooting assembly and the second camera shooting assembly are switched, the zooming process is more natural and smooth, and a better preview effect is realized.
For example, the above-mentioned super-sampling of the current image may be performed by a bicubic interpolation method. For example, referring to fig. 2, for the current image, the values of 16 pixels (a00, a01 … a33) around the pixel P in the current image may be selected as the parameter references of the pixel values corresponding to the replacement image. Specifically, the formula may include:
wherein r, c are pixel positions of rows and columns, PijIs the corresponding pixel value. Wherein i, j is 1, 2, 3, 4.
The super-resolution calculation formula comprises:
wherein, aijIs a super-resolution factor calculated byLagrangian equations may be utilized:
where s is a set super-resolution coefficient, and different values may be specifically set according to the actual processing capability of the electronic device. For example, s-ceil () may be configured to return an integer value having a magnitude greater than or equal to the value in parentheses, resulting in ai，bjThen, the matrix operation obtains aijMatrix, creating a high resolution image. Specifically, the formula may include:
the oversampling by the bicubic interpolation method can be realized by adopting the means of the prior art, and the specific contents of the process of the other side of the disclosure are not repeated. In other exemplary embodiments of the present disclosure, the current image may also be super-sampled by using a bilinear interpolation method, for example, values of the nearest four pixel points in the current image are selected as parameter references of pixel values corresponding to the replacement image. Specifically, the specifically executed super sampling method may be determined according to the resolution of the current image, or the specification of the first camera assembly. For example, the CPU of the electronic device may identify and analyze the current image and determine the type of oversampling method specifically used based on the identification result.
Based on the above, in the present exemplary embodiment, referring to fig. 3, the method described above may further include:
and step S14, when the current focusing parameter is identified to exceed the first conversion range and to be in a second zooming range corresponding to the second camera shooting assembly, displaying the current image collected by the second camera shooting assembly.
In the present exemplary embodiment, the first transformation range may have a certain overlap region with the zoom factor range of the first image capturing assembly and the zoom factor range of the second image capturing assembly, as in the example described in the above embodiment. When the focusing multiple corresponding to the current touch operation of the user is recognized to exceed the zoom multiple range corresponding to the first camera shooting assembly, exceed the first conversion range at the same time and be in the second zoom range of the second camera shooting assembly, the current image corresponding to the second camera shooting assembly can be directly switched and displayed. For example, displaying the surfview (view) corresponding to the second camera assembly in the preview view acquires the corresponding preview data. The second camera shooting assembly is started, and a corresponding preview image is generated in real time according to the zooming operation of the user and is not displayed in the preview interface of the electronic equipment. Therefore, such an operation can make the view switching smoother.
In addition, after the current zoom multiple exceeds the first conversion range, the image collected by the first camera shooting assembly is not needed, and the first camera shooting assembly can be subjected to sleep, suspension or closing operation. Thereby reducing power consumption.
Furthermore, in other exemplary embodiments of the present disclosure, the method described above may further include: and when the current focusing parameter is identified to be in the overlapping range, carrying out fusion processing on the replacement image and the current image acquired by the second camera shooting assembly to obtain a fusion image, and displaying the fusion image.
For example, if the current zoom factor is 5.5, the current zoom factor is within the first variable range while being within the zoom range of the second camera assembly. Since the second camera shooting assembly is started and collects images at the moment, image fusion processing is carried out on the replacement images generated by collecting the images based on the first camera shooting assembly and the current images collected by the second camera shooting assembly according to the current zoom multiple, and the poor areas in the replacement images are supplemented by the current images collected by the second camera shooting assembly. And the fused image is output and displayed in the preview view, so that the quality of the image displayed in the preview view is improved. For example, in order to ensure the speed of the image fusion process, the image fusion may adopt a fusion method based on weighted average. Alternatively, a pyramid transform-based fusion algorithm or the like may also be employed.
In addition, in other exemplary embodiments of the present disclosure, after the second camera shooting assembly is started, the first camera shooting assembly and the second camera shooting assembly may be synchronized, so that the second camera shooting assembly and the first camera shooting assembly synchronously capture a current image corresponding to a current scene.
For example, the CPU of the electronic device may simultaneously send the synchronization control signals to the first camera shooting assembly and the second camera shooting assembly, respectively, so that the first camera shooting assembly and the second camera shooting assembly can synchronously acquire the current image corresponding to the current scene after receiving the control signals. Alternatively, the first image pickup unit may transmit the synchronization signal to the second image pickup unit. Therefore, when the focal length is changed and the first camera shooting assembly is switched to the second camera shooting assembly, the image content in the preview interface is ensured to be accurate.
In other exemplary embodiments of the present disclosure, after activating the second camera assembly, the method may further include: acquiring a first shooting parameter corresponding to the current image acquired by the first camera shooting assembly, and adjusting the first shooting parameter based on a preset rule to acquire a second shooting parameter so that the second camera shooting assembly executes the second shooting parameter.
For example, there is a certain difference between the first camera shooting component and the second camera shooting component in hardware, and in order to ensure consistency of image display effects in the preview interface before and after switching of the camera shooting components, the second shooting parameters corresponding to the second camera shooting component can be adjusted according to the current first shooting parameters of the first camera shooting component. For example, the photographing parameters may include: focus, background blurring, sensitivity, exposure compensation, white balance, and the like. A parameter comparison table of the corresponding relationship between the first shooting parameter of the first camera shooting assembly and the second shooting parameter of the second camera shooting assembly can be established in advance, so that the current second shooting parameter can be determined by using the first shooting parameter.
In this exemplary embodiment, after the user enters the camera application, the first camera shooting component and the second camera shooting component may also be started at the same time, and pipeline and surface view may be configured for the first camera shooting component and the second camera shooting component, respectively. And each camera shooting assembly respectively collects images, and transmits the images to corresponding faceview by using the pipeline corresponding to each camera shooting assembly, so that multi-path preview is realized. And displaying the current image acquired by the corresponding camera shooting assembly on a preview interface according to the current focusing parameter, and hiding the current image acquired by the other camera shooting assembly.
According to the image processing method provided by the embodiment of the disclosure, the transformation range is set for the zooming of the camera shooting assembly, so that when the current zooming parameter of the camera shooting assembly enters the preset transformation range, the corresponding camera shooting assembly is activated to start image acquisition, but the image acquisition is not displayed in the preview interface. Meanwhile, a certain overlapping range is reserved between the control conversion range and the zooming ranges of the two camera assemblies, so that after the current zooming parameter enters a preset conversion range, the image acquired by the current camera assembly is subjected to super-sampling processing, and when the current zooming parameter controlled by a user is in the conversion range, the current image acquired by the first camera assembly is subjected to super-sampling processing to generate a replacement image. And when the current zoom parameter controlled by the user exceeds the conversion range and is within the zoom range corresponding to the second camera shooting assembly, displaying the current image collected by the second camera shooting assembly. Therefore, the first camera shooting assembly and the second camera shooting assembly have the problems of image blurring and blocking when the focal length of the zoom switching is changed to the critical point, the zooming process is smooth and clear, the image quality is improved, and the user can take pictures with high quality.

It will be readily understood that the processes shown in the above figures are not intended to indicate or limit the chronological order of the processes.
