The embodiment of the application provides a photographing method and device, electronic equipment and a storage medium.
The photographing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 is a flowchart of a photographing method provided in an embodiment of the present application, and as shown in fig. 1, the method may include the following steps: step 101, step 102 and step 103, wherein,
in step 101, focus information of N photo-taking regions is obtained, where the N photo-taking regions are obtained by performing region division on a current photo-taking scene, and N is an integer greater than 1.
In the embodiment of the application, the N shooting areas form a complete current shooting scene.
In the embodiment of the present application, the focusing information may include: a focus 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 the embodiment of the application, focusing information of at least two photographing regions in the N photographing regions is different.
In the embodiment of the application, when a focusing instruction is received, the focusing information of the N photographing regions is acquired, wherein the focusing instruction can be triggered by a user. For example, when a user needs to take a picture, the user takes out the electronic device, opens the camera, and clicks a camera screen to trigger a focusing instruction.
In the embodiment of the present application, a camera of an 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 photo chip, which may be divided into 3 × 3 equal parts to obtain 9 photo-sensitive areas with the same size, namely, photo-sensitive area 1, photo-sensitive area 2, photo-sensitive area 3, photo-sensitive area 4, photo-sensitive area 5, photo-sensitive area 6, photo-sensitive area 7, photo-sensitive area 8, and photo-sensitive area 9.
The process of the photosensitive chip works as follows: 1) a light particle signal receiver (sensor) on the photosensitive chip receives a photon signal; 2) the analog current signal received by the optical particle signal receiver is amplified into a voltage signal by a signal amplifier; 3) the analog signals are converted into digital signals through the ADC, and finally the photosensitive chip outputs the digital signals on different pixel positions.
In this embodiment of the application, when the photosensitive chip is divided into N photosensitive regions, the step 101 may specifically include the following steps:
focusing the N photographing areas through N photosensitive areas in the camera to obtain N focusing information; the N photosensitive areas are obtained by dividing a 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 camera of the electronic device focuses on one photographing area in the current photographing scene, and the N photosensitive areas focus on the N photographing areas simultaneously.
In an embodiment provided by the present application, focusing may be performed on N photographing regions by controlling deformation of a photosensitive film in each photosensitive region, specifically:
for each photographing region, controlling the deformation of a photosensitive film of a photosensitive region corresponding to the photographing region by adjusting the electromagnetic force with different intensities, and calculating the contrast of a 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 the embodiment of the application, the photosensitive chip can be divided into a plurality of areas, the photosensitive film in each area can be deformed by electromagnetically controlling the film of the photosensitive chip, so that the photosensitive chip generates relative displacement, and then the digital signal in the area is obtained through the steps 2) and 3).
In an example, taking the focusing of the photosensitive area 1 as an example, during the focusing, the photosensitive area 1 is deformed to different degrees by electromagnetic forces with different intensities with respect to the photosensitive area 1, and specifically, the photosensitive film of the photosensitive area is 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, and the closer the photosensitive film is to the lens, the farther the focusing distance is.
In the embodiment of the application, in the process that the photosensitive film is uniformly deformed, the focusing distance is also uniformly changed, and the contrast of the digital image 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 by the present application, a mechanical structure of the photosensitive chip may be changed, so that each photosensitive area of the photosensitive chip can freely move back and forth along a central line direction of the lens, to focus the N photographing areas, specifically:
each photosensitive area is connected with the voice coil motor, the voice coil motor drives the photosensitive areas to move so as to support each photosensitive area of the photosensitive chip to move freely, the contrast of digital images of the photosensitive areas at different positions is calculated, and focusing information of the photographing areas corresponding to the photosensitive areas is obtained.
In the embodiment of the present application, the electronic device may also include: the photosensitive chip comprises a plurality of movable photosensitive chips, and each photosensitive chip corresponds 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 of the corresponding field object, and respective focusing information is adjusted through contrast focusing.
In the embodiment of the 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 regions shown in fig. 2, and when focusing is performed, the lens divides the current photographing scene into 9 photographing regions through the photographing preview interface according to the division rule of the photosensitive regions shown in fig. 2, where each photosensitive region corresponds to one photographing region.
In the embodiment of the present application, the current photographing scene may also be divided into three regions according to other rules, for example, the photographing scene is divided into three equal parts from left to right according to a rule preset by a user, so as to obtain 3 photographing regions, which is not limited in the embodiment of the present application.
In step 102, focusing parameters of the N photographing regions are determined according to the focusing information.
In an embodiment provided by the present application, when the focusing information includes a focusing distance, the step 102 may specifically include the following steps:
for each photographing region, the focusing distance of the photographing region is determined as the focusing parameter of the photographing region.
In the embodiment of the application, for each photographing region, deformation of a photosensitive film of a photosensitive region corresponding to the photographing region is controlled by adjusting electromagnetic force with different intensities, the contrast of digital images of the photosensitive region under different intensities is calculated to obtain the focusing distance of the photographing region corresponding to the photosensitive region, 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 by the present application, when the focusing information includes a focusing distance and a color parameter for photographing, the step 102 may specifically include the following steps:
calculating target color parameters according to the color parameters of the N photographing regions;
for each photographing region, determining the focusing distance and the target color parameter of the photographing region as the focusing parameters of the photographing region, wherein the color parameters comprise one or more of the following items: 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, and completes one-time focusing photographing according to the automatic focusing distance, the photographed image has the problem of local defocus blur, and besides, the information of focusing parameters such as brightness, contrast, white balance and the like acquired through one-time focusing is inaccurate, some areas in the photographed image are dark, other areas are bright, and the image has low restoration degree to the photographed scene.
In order to solve the above problem, in the embodiment of the present application, it is considered that different focus distances correspond to different color parameters, and different color parameters correspond to different imaging effects, so that in order to ensure that a finally shot image can highly restore a shooting scene, after a plurality of photosensitive regions in an electronic device respectively focus different shooting regions of a current shooting scene, the focus distances of the plurality of shooting regions are obtained, and simultaneously, the color parameters of the plurality of shooting regions at the focus distances are obtained.
In one example, a camera of the electronic device includes 9 photosensitive areas shown in fig. 2, and after focusing is completed, the focusing distance of a photographing area corresponding to the 9 photosensitive areas is obtained, and the color parameters of the 9 photographing areas are obtained at the same time.
In the embodiment of the present application, after the color parameters of the plurality of photographing regions are obtained, a suitable target color parameter, such as a suitable brightness, a suitable contrast, and a suitable white balance, is calculated according to the color parameters of the plurality of photographing regions.
In the embodiment of the application, when the target color parameter is calculated according to the color parameters of the plurality of photographing regions, the average value of the color parameters of the plurality of photographing regions can be calculated, and the average value is determined as the target color parameter.
For example, a uniform brightness parameter is obtained by calculating the average brightness value according to the brightness of different photographing regions; according to the contrast of different photographing areas, a uniform contrast parameter is obtained by calculating the average value of the contrast; and according to the white balance of different photographing areas, a uniform white balance parameter is obtained 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 all photosensitive areas of the lens, and the color parameters of all the photosensitive areas are adjusted to the target color parameters.
Therefore, in the embodiment of the application, when focusing is performed, the focusing distances of different shooting areas can be respectively adjusted according to the distances of the objects corresponding to the field of view in the current shooting scene, so that when some close-range scenes are shot, the shot images are prevented from being out of focus and blurred, and the shot images are clear and accurate; in addition, the different photographing areas adopt uniform color parameters, so that the photographed image has higher reduction degree and is more real to the photographing scene, and the photographing effect is improved.
In step 103, an image is captured based on the focusing parameters to obtain a target image.
In the embodiment of the application, under the condition that the N photosensitive areas are at the focusing positions corresponding to the respective focusing distances and the photographing color parameters of the N photosensitive areas are adjusted to be the target color parameters, a lens in a camera is controlled to photograph, so that the RGB values of all pixel points in the N photosensitive areas are obtained; and generating a target image according to the RGB values of all the pixel points in the N photosensitive areas.
In order to facilitate understanding of the differences between the technical solutions of the present application and the prior art, the description is made with reference to the examples shown in fig. 3 and 4.
Fig. 3 illustrates a focusing scheme in the prior art, in which a camera of an electronic device includes only one photosensitive chip, and when a photographed scene includes a long shot and a short shot at the same time, a focusing position of the photosensitive chip is position 1 for the long shot; for a close shot, the focusing position of the photosensitive chip is position 2, and since the photosensitive chip can only move uniformly and only one focusing position can be provided for one-time shooting, and the position 1 and the position 2 cannot be considered simultaneously, only a compromise position can be calculated, and the shot image is shot at the compromise position, so that the shot image has local out-of-focus blur.
Fig. 4 shows a focusing scheme in the present application, and a camera of an electronic device includes a photosensitive chip, which is divided into several areas, for example, 9 areas, and each photosensitive area can move freely. For convenience of description, taking 3 photosensitive regions out of 9 as an example, when a photographed scene includes a long shot, a short shot 1, and a short shot 2, the focus position of the photosensitive region 1 is position 1 for the long shot; for the close shot 1, the focus position of the photosensitive area 2 is position 2; for the close shot 2, the focus position of the photosensitive area 3 is position 3; because each area of the photosensitive chip can move respectively, one photosensitive area can correspond to one focusing position after being shot once, different photosensitive areas can correspond to different focusing positions after being shot once, and the position 1, the position 2 and the position 3 can be considered simultaneously, the shot image is clearer, and the local defocus blur does not exist.
As can be seen from the above embodiments, in the embodiment, for the current photographing scene, a camera in the electronic device may focus different regions of the current photographing scene at the same time, obtain focusing information of the different regions, determine focusing parameters of the different regions according to the focusing information, and photograph an image based on the focusing parameters to obtain a target image. Compared with the prior art, in the embodiment of the application, the camera can acquire focusing information of different areas according to the distance between a field object in different areas of a current shooting scene and the camera lens, and shoots images of the current shooting scene based on the focusing information of the different areas, so that when some close-range scenes are shot, the images obtained by shooting are prevented from being out of focus and blurred, the shot images are clear and accurate, and the shooting effect is improved.
