It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The shooting method, the shooting device, the electronic device and the readable storage medium provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings by specific embodiments and application scenarios thereof.

In an embodiment of the present application, a shooting method is proposed, which is applied to a shooting device, wherein, as shown in fig. 1 and fig. 2, the shooting device includes: the camera comprises a first camera 110, a second camera 120, a third camera 130 and a fourth camera 140, wherein the first camera 110 comprises a Bayer array sensor, the second camera 120 comprises a red filter, the third camera 130 comprises a green filter, and the fourth camera 140 comprises a blue filter.

As shown in fig. 3, the photographing method includes:

step 202, controlling a first camera to acquire an RGB image, a second camera to acquire a red image, a third camera to acquire a green image and a fourth camera to acquire a blue image;

and step 204, obtaining a target image based on the RGB image, the red image, the green image and the blue image.

The first camera comprises a Bayer array sensor, and when the first camera shoots, RGB images can be acquired. Since the bayer array sensor is composed of three small filters of red, green, and blue colors alternately, images of R-channel image data, G-channel image data, and B-channel image data are captured alternately, and then RGB images are obtained by demosiac (demosaicing) processing.

The second camera comprises a red optical filter, and a red image can be acquired when the second camera shoots. In the second camera, a red filter replaces a Bayer array sensor, and after the red filter filters light, a complete red image can be obtained.

The third camera includes green filter, and the third camera can gather and obtain green image when shooing. In the third camera, a green filter replaces a Bayer array sensor, and after the green filter filters light, a complete green image can be acquired.

The fourth camera comprises a blue optical filter, and when the fourth camera shoots, a blue image can be acquired. In the fourth camera, a blue filter is used for replacing a Bayer array sensor, and after the blue filter filters light, a complete blue image can be obtained.

And under the condition of receiving the shooting input, the first camera, the second camera, the third camera and the fourth camera shoot simultaneously. Thus, one RGB image, one red image, one green image, and one blue image can be obtained through one shooting. And then fusing the color image, the red image, the green image and the blue image to obtain a final target image.

In one possible embodiment, deriving the target image based on the RGB image, the red image, the green image, and the blue image comprises: based on the RGB image, obtaining R channel image data, G channel image data and B channel image data; fusing R channel image data and a red image to obtain a red fused image, fusing G channel image data and a green image to obtain a green fused image, and fusing B channel image data and a blue image to obtain a blue fused image; and fusing the red fused image, the green fused image and the blue fused image to obtain a target image.

In the case of taking a red image, a green image, and a blue image, since pixels in the red image, the green image, and the blue image are relatively complete, demosiac processing is not required.

And fusing the red image with R channel image data decomposed from the RGB image to obtain a red fused image. And fusing the green image with the G channel image data decomposed from the RGB image to obtain a green fused image. And fusing the blue image and B-channel image data decomposed from the RGB image to obtain a blue fused image. And then fusing the three fused images to obtain a target image. Because the target image is the image subjected to fusion processing, the color of the target image is accurate, richer and clearer, and the problems of inaccurate image color and edge information loss in the related technology are solved.

In a possible embodiment, after obtaining the R channel image data, the G channel image data, and the B channel image data based on the RGB image, the method further includes: and carrying out alignment processing on the R-channel image data and the red image, carrying out alignment processing on the G-channel image data and the green image, and carrying out alignment processing on the B-channel image data and the blue image.

Due to the fact that shooting positions of the first camera, the second camera, the third camera and the fourth camera are different, images shot by different cameras may also be different. Therefore, when the RGB image, the red image, the green image, and the blue image are captured, it is necessary to compare the red image, the green image, and the blue image with the RGB image, respectively, and determine whether the red image, the green image, and the blue image have the problem of redundant information or image distortion.

The first camera may be used as the main camera and then images captured by other cameras may be compared with the image captured by the first camera.

Specifically, after the R-channel image data is aligned with the red image, it can be determined whether there is unnecessary information in the red image or whether the image is distorted. For example, if a single person image is captured in the RGB image and an animal image appears in the red image, the animal image in the red image is an unnecessary image. In the case where the unnecessary information is determined, the red image needs to be clipped so as to delete the unnecessary information in the red image. The cut parts in the red image are not fused with the RGB image, and the uncut parts in the red image are aligned with the RGB image and fused.

As shown in fig. 4, the first region 610 shows a person image, and the second region 620 in fig. 5 is an unnecessary image compared to fig. 4, and the second region 620 is not shown in fig. 4, so that the image within the dotted line frame needs to be removed.

If the red image has distorted images, the image proportion in the red image is adjusted based on the image proportion of the RGB image.

As shown in fig. 6, the image in the third region 630 shows a head that is malformed with respect to the head of the person in fig. 4, and therefore correction of the head of the person is required.

The alignment process of the green image and the blue image with the RGB image is the same.

Through aligning the red image, the green image, the blue image and the RGB image, redundant information can be removed, and distortion in the image is corrected, so that the red image, the green image, the blue image and the RGB image are more accurately fused, the fusion effect is favorably improved, and the image shooting effect is further improved.

In a possible embodiment, the photographing method further includes: and displaying a pixel weight setting interface, wherein the pixel weight setting interface is used for setting the image fusion proportion.

The user can adjust the weight ratio of the red pixel, the green pixel and the blue pixel, so that the ratio of the red pixel, the green pixel and the blue pixel in the target image is more suitable for the requirement of the user.

Specifically, in the case of entering the pixel weight setting interface, the user can set the weight ratio of the red pixel, the green pixel, and the blue pixel. As shown in fig. 10, the user may click the "R" control, and at this time, a filling box of weight values appears on the display interface of the electronic device, and the data range is between 0 and 1, and the user may fill the weight ratio of the red pixel in the filling box. Similarly, the "G" control may be clicked to fill in the weight fraction of green pixels, and the "B" control may be clicked to fill in the weight fraction of blue pixels.

For red, green and blue pixels, if the weights set by the user are wr, wg and wb, respectively, the image captured by the first camera is x, and the images captured by the second, third and fourth cameras are R, G, B, respectively, the final picture Y obtained in the pixel weight adjustment mode can be represented as: y ═ x + wr × R + wg × G + wb × B.

And finally Y is a picture output to the user. Illustratively, if the user prefers a somewhat redder picture style, the weighting of the red pixels may be increased to get the final picture. Because the details of the images shot by the second camera, the third camera and the fourth camera are completely reserved and the monochrome information is richer, the quality of the images finally obtained by the user is higher, and the preference tendency of the user is better met by adjusting the pixel weight.

In a possible embodiment, before the first camera acquires the RGB image, the method further includes: receiving a first input of a user; and responding to the first input, and entering a target shooting mode, wherein the target shooting mode is used for indicating and controlling the first camera, the second camera, the third camera and the fourth camera to simultaneously acquire images.

The target shooting mode can be a special shooting mode, a user enters the special shooting mode by clicking a special shooting control on the electronic equipment, and in the special shooting mode, when the user shoots, the RGB image, the red image, the green image and the blue image are fused to obtain a high-quality target image.

As shown in fig. 7, the user may click a "special shoot" control in the display interface 640, and the electronic device enters the target shooting mode.

And under the condition that the target shooting mode is not entered, the electronic equipment is in a normal shooting mode, and in the normal shooting mode, an image is obtained only through shooting by the first camera. Different shooting requirements of users can be met by setting different shooting modes.

As shown in fig. 8, in the display interface 660, there are two controls of "high quality imaging" and "special fusion". As shown in fig. 9, in the display interface 670, the user may click on the "high quality imaging" control, at which time the user may capture a high quality image using the electronic device. If the "special blend" control is clicked, the process proceeds to the display interface 691 shown in fig. 10, that is, the pixel weight setting interface, where the weight ratios of the red pixel, the green pixel, and the blue pixel can be set.

In a possible embodiment, the number of the third cameras is two, and the two third cameras respectively acquire two green images; fusing G channel image data with a green image to obtain a green fused image, comprising: and fusing the G channel image data with the two green images to obtain a green fused image.

The number of the third cameras is two, when high-quality shooting is carried out, two green images can be obtained, and due to the fact that human eyes are more sensitive to green, accuracy of green in the target image is improved by collecting the two green images, and quality of the target image is further improved.
