The embodiment of the application provides a photographing method, a photographing device, electronic equipment and a storage medium.
The photographing method provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Fig. 1 is a flowchart of a photographing method according to an embodiment of the present application, as shown in fig. 1, the method may include the following steps: step 101, step 102 and step 103, wherein,
in step 101, focusing information of N photographing areas is obtained, where the N photographing areas are obtained by dividing a current photographing scene into areas, and N is an integer greater than 1.
In the embodiment of the application, N photographing areas form a complete current photographing scene.
In the embodiment of the present application, the focusing information may include: a focusing distance; alternatively, the focusing information may include: a focus distance and a color parameter of the photograph, wherein the color parameter may include one or more of: light intensity, contrast, and white balance.
In this embodiment of the present application, at least two of the N photographing regions have different focusing information.
In this embodiment of the present application, when a focusing instruction is received, focusing information of N photographing areas is obtained, where the focusing instruction may be triggered by a user. For example, when a user has a photographing requirement, the electronic device is taken out, the camera is opened, and a focusing instruction can be triggered by clicking a camera screen.
In this embodiment, the camera of the electronic device may include a photosensitive chip, and the photosensitive chip may be divided into a plurality of photosensitive areas, where each photosensitive area is a part of the photosensitive chip. For example, as shown in fig. 2, the camera includes a photosensitive chip, which may be equally divided by 3×3 to obtain 9 photosensitive areas with the same size, i.e., photosensitive area 1, photosensitive area 2, photosensitive area 3, photosensitive area 4, photosensitive area 5, photosensitive area 6, photosensitive area 7, photosensitive area 8, and photosensitive area 9.
The process of the photosensitive chip works as follows: 1) An optical particle signal receiver (sensor) on the photosensitive chip receives the photon signal; 2) The analog current signal received by the optical particle signal receiver is amplified into a voltage signal through a signal amplifier; 3) The analog signals are converted into digital signals through the ADC, and finally the digital signals at different pixel positions are output by the photosensitive chip.
In this embodiment, when the photosensitive chip is divided into N photosensitive areas, the step 101 may specifically include the following steps:
focusing N photographing areas simultaneously through N photosensitive areas in the camera to obtain N pieces of focusing information; the N photosensitive areas are obtained by dividing one photosensitive chip in the camera into areas, and one photosensitive area corresponds to one photographing area.
In the embodiment of the application, one photosensitive area in the electronic equipment camera focuses on one photographing area in the current photographing scene, and N photosensitive areas focus on N photographing areas at the same time.
In one embodiment provided in the present application, the N photographing regions may be focused by controlling the deformation of the photosensitive film in each of the photosensitive regions, specifically:
for each photographing region, controlling the photosensitive film of the photosensitive region corresponding to the photographing region to deform by adjusting the electromagnetic force of different intensities, and calculating the contrast of the digital image of the photosensitive region under different intensities to obtain focusing information of the photographing region corresponding to the photosensitive region; the photosensitive areas are obtained by distinguishing and dividing one photosensitive chip in the camera, and one photosensitive area corresponds to one photographing area.
In this embodiment of the present application, the photosensitive chip may be divided into a plurality of areas, and the photosensitive film in each area may be deformed by electromagnetic control, so that the photosensitive chip may generate relative displacement, and then the digital signal in the area may be obtained through the steps 2) and 3).
In one example, taking focusing of the photosensitive area 1 as an example, during focusing, the photosensitive area 1 is deformed to different degrees by electromagnetic forces with different intensities, specifically, the photosensitive film of the photosensitive area can be uniformly deformed by uniformly changing the electromagnetic intensity from weak to strong.
In the embodiment of the application, the stronger the electromagnetic force is, the larger the deformation of the photosensitive film of the photosensitive chip is, the farther the photosensitive film is from the lens, and the closer the focusing distance is; the weaker the electromagnetic force is, the smaller the deformation of the photosensitive film on the photosensitive chip is, the closer the photosensitive film is to the lens, and the farther the focusing distance is.
In the embodiment of the application, in the process of uniformly deforming the photosensitive film, the focusing distance is uniformly changed, and the digital image contrast of the current photosensitive area under different intensities is calculated to obtain the optimal focusing position of the area. All photosensitive areas of the whole photosensitive chip are focused in the same way.
In another embodiment provided in the present application, the mechanical structure of the photosensitive chip may be changed, so that each photosensitive area of the photosensitive chip may freely move back and forth along the direction of the center line of the lens, to focus on N photographing areas, specifically:
each photosensitive area is connected with a voice coil motor, the photosensitive areas are driven to move through the voice coil motor so as to support the free movement of each photosensitive area of the photosensitive chip, the contrast of digital images of the photosensitive areas at different positions is calculated, and focusing information of photographing areas corresponding to the photosensitive areas is obtained.
In the embodiment of the present application, the electronic device may further include: and the movable photosensitive chips correspond to one photosensitive area.
In the embodiment of the application, when focusing is performed, different photosensitive areas can move back and forth along the central axis direction of the lens according to the distance between the corresponding field objects, and respective focusing information is adjusted through contrast focusing.
In this embodiment of the present application, when the current photographing scene is divided into regions, the division rule may be the same as the division rule of the photosensitive regions, and one photographing region in the current photographing scene corresponds to one photosensitive region of the photosensitive chip. For example, the camera includes 9 photosensitive areas shown in fig. 2, and when focusing is performed, the lens divides the current photographing scene into 9 photographing areas through the photographing preview interface according to the division rule of the photosensitive areas shown in fig. 2, and each photosensitive area corresponds to one photographing area.
In this embodiment of the present application, the current photographing scene may be divided into regions according to other rules, for example, the photographing scene is halved from left to right according to a rule preset by a user, so as to obtain 3 photographing regions, which is not limited in this embodiment of the present application.
In step 102, focusing parameters of the N photographing regions are determined according to the focusing information.
In one embodiment provided in the present application, when the focusing information includes a focusing distance, the step 102 may specifically include the following steps:
for each photographing region, determining the focusing distance of the photographing region as the focusing parameter of the photographing region.
In the embodiment of the application, for each photographing region, the deformation of the photosensitive film of the photosensitive region corresponding to the photographing region is controlled by adjusting the electromagnetic force of different intensities, the contrast of the digital image of the photosensitive region under different intensities is calculated, the focusing distance of the photographing region corresponding to the photosensitive region is obtained, and the focusing distance of the photographing region is determined as the focusing parameter of the photographing region; the photosensitive areas are obtained by distinguishing and dividing one photosensitive chip in the camera, and one photosensitive area corresponds to one photographing area.
In another embodiment provided in the present application, when the focusing information includes a focusing distance and a photographed color parameter, the step 102 may specifically include the following steps:
calculating target color parameters according to the color parameters of the N photographing areas;
for each photographing region, determining a focusing distance of the photographing region and a target color parameter as focusing parameters of the photographing region, wherein the color parameters comprise one or more of the following: light intensity, contrast, and white balance.
In consideration of the fact that in the prior art, an electronic device calculates an automatic focusing distance through one or more times of focusing, one-time focusing photographing is completed according to the automatic focusing distance, besides the problem that local defocus blur exists in a photographed image, focusing parameters such as brightness, contrast, white balance and the like obtained through one-time focusing are inaccurate, some areas in the photographed image are dark, other areas are bright, and the reduction degree of the photographed image to a photographed scene is low.
In order to solve the above problem, in the embodiment of the present application, different focusing distances are considered to correspond to different color parameters, and different color parameters correspond to different imaging effects, so in order to ensure that a finally photographed image can highly restore a photographed scene, after a plurality of photosensitive areas focus on different photographed areas of a current photographed scene in an electronic device, the focusing distances of a plurality of photographed areas are obtained, and at the same time, the color parameters of the plurality of photographed areas under the focusing distances of the plurality of photographed areas are obtained.
In one example, the camera of the electronic device includes 9 photosensitive areas shown in fig. 2, and after focusing is completed, the focusing distances of the photographing areas corresponding to the 9 photosensitive areas are obtained, and meanwhile, the color parameters of the 9 photographing areas are obtained.
In this embodiment, after the color parameters of the plurality of photographing regions are obtained, a suitable target color parameter is calculated according to the color parameters of the plurality of photographing regions, for example, suitable brightness, contrast and white balance are calculated.
In this embodiment of the present application, when calculating the target color parameter according to the color parameters of the plurality of photographing regions, the average value of the color parameters of the plurality of photographing regions may be calculated, and the average value is determined as the target color parameter.
For example, according to the brightness of different photographing areas, a uniform brightness parameter is obtained by calculating the average value of the brightness; according to the contrast of different photographing areas, a unified contrast parameter is obtained by calculating a contrast average value; and according to the white balance of different photographing areas, obtaining a uniform white balance parameter by calculating the average value of the white balance.
In the embodiment of the application, after the reasonable target color parameters are calculated, the target color parameters are sent to each photosensitive area of the lens, and the color parameters of each photosensitive area are adjusted to the target color parameters.
In the embodiment of the application, when focusing is performed, different photographing areas can respectively adjust respective focusing distances according to the distance between the object in the corresponding field of view in the current photographing scene, so that when photographing some short-distance scenes, defocusing and blurring are avoided in the photographed images, and the photographed images are clear and accurate; in addition, the uniform color parameters are adopted in different photographing areas, so that the photographed image has higher and more real reduction degree on a photographing scene, and the photographing effect is improved.
In step 103, an image is captured based on the focus parameter, and a target image is obtained.
In the embodiment of the application, under the condition that N photosensitive areas are positioned at focusing positions corresponding to focusing distances respectively and photographing color parameters of the N photosensitive areas are all adjusted to target color parameters, a lens in a camera is controlled to photograph, and RGB values of pixel points in the N photosensitive areas are obtained; and generating a target image according to the RGB values of each pixel point in the N photosensitive areas.
To facilitate understanding of the differences between the technical solutions of the present application and the prior art, the description is made in connection with the examples shown in fig. 3 and 4.
Fig. 3 shows a focusing scheme in the prior art, wherein a camera of an electronic device only comprises a photosensitive chip, and when a shooting scene comprises a far view and a near view at the same time, the focusing position of the photosensitive chip is a position 1 for the far view; for close-up, the focusing position of the photosensitive chip is the position 2, and because the photosensitive chip can only uniformly move and can only have one focusing position for one shooting, the position 1 and the position 2 cannot be simultaneously considered, only one compromise position can be calculated, and shooting is carried out at the compromise position, so that the shot image has local defocus blur.
Fig. 4 shows a focusing scheme in the present application, in which a camera of an electronic device includes a photosensitive chip, and the photosensitive chip is divided into several areas, for example, 9, and each photosensitive area is freely movable. For convenience of description, taking 3 photosensitive areas out of 9 as an example, when a shooting scene contains a far view, a near view 1 and a near view 2 at the same time, for the far view, the focusing position of the photosensitive area 1 is a position 1; for close-up 1, the focus position of photosensitive area 2 is position 2; for close-up 2, the focus position of photosensitive area 3 is position 3; because each region of the photosensitive chip can move respectively, one photosensitive region can correspond to one focusing position, and different photosensitive regions can correspond to different focusing positions, and the position 1, the position 2 and the position 3 can be simultaneously considered, the shot image is clearer, and local defocusing and blurring do not exist.
In the embodiment, for the current photographing scene, the camera in the electronic device may focus different areas of the current photographing scene at the same time, obtain focusing information of the different areas, determine focusing parameters of the different areas according to the focusing information, and photograph an image based on the focusing parameters to obtain a target image.
