Referring to fig. 2, fig. 3 and fig. 4, in the present embodiment, the base 10 carries the first camera 20, the second camera 30 and the third camera 40. The first camera 20, the second camera 30 and the third camera 40 are fixed to each other. The first, second and third

photosensitive chips

21, 31 and 41 are parallel to each other. Namely, the main shooting optical axis of the first camera 20, the main shooting optical axis of the second camera 30, and the main shooting optical axis of the third camera 40 are parallel to each other. The first camera 20, the second camera 30 and the third camera 40 are arranged at intervals. That is, the first photosensitive chip 21, the second photosensitive chip 32, and the third photosensitive chip 42 are spaced apart from each other. To reduce the mutual electromagnetic interference of the first camera 20, the second camera 30 and the third camera 40.

The length and width dimensions of the first photosensitive chip 21, the length and width dimensions of the second photosensitive chip 312, and the length and width dimensions of the third photosensitive chip 41 are all the same. A plurality of first photosensitive points 211 are arranged on the first photosensitive chip 21 in an array, second photosensitive points 311 with the same number as that of the first photosensitive chips 211 are arranged on the second photosensitive chip 31 in an array, and third photosensitive points 411 with the same number as that of the first photosensitive chips 21 are arranged on the third photosensitive chip 41 in an array. The maximum size of the shot image acquired by the first photosensitive chip 21 is the same as the maximum size of the shot image acquired by the second photosensitive chip 32, and the maximum size of the shot image acquired by the first photosensitive chip 21 is the same as the maximum size of the shot image acquired by the third photosensitive chip 42, so that the image acquired by the first photosensitive chip 21, the image acquired by the second photosensitive chip 31 and the image acquired by the third photosensitive chip 41 can be synthesized conveniently.

The length and width of the first filter 22 are substantially the same as those of the first photosensitive chip 21. The first filter 22 is laminated with the first photosensitive chip 21 in a normal direction of the first photosensitive chip 21. The edge of the first filter 2 is approximately aligned with the edge of the first photosensitive chip 21, so that the first camera 20 is compact. The length and width of the second filter 32 are substantially the same as those of the second photosensitive chip 31. The second filter 32 is laminated with the second photosensitive chip 31 in a normal direction of the second photosensitive chip 31. The edge of the second filter 32 is substantially aligned with the edge of the second photosensitive chip 31, so that the second camera 30 is compact. The length and width of the third filter 42 are substantially the same as those of the third photosensitive chip 41. The third filter 42 is stacked with the third photosensitive chip 41 in a normal direction of the third photosensitive chip 41. The edge of the third filter 42 is substantially aligned with the edge of the third photosensitive chip 41, so that the third camera 40 is compact. The first filter 22 may be bonded to the first photosensitive chip 21. The second filter 32 may be attached to the second photosensitive chip 21. The third filter 42 may be attached to the third photosensitive chip 41. Of course, in other embodiments, there may be a space between the first filter 22 and the first photosensitive chip 21. There may be a space between the second filter 32 and the second photosensitive chip 31. There may be a space between the third filter 42 and the third photosensitive chip 41.

The first photosensitive points 211 sense light, and present pixel points on an image after being processed by the central processing unit, thereby obtaining the image. Since the light collected by the first light sensing chip 21 passes through the first optical filter 22, the light collected by the first light sensing point 211 is filtered by the pigment of the first optical filter 22, that is, the color information of each pixel point of the image can be obtained by processing the sensing signal of each first light sensing point 211 by the central processing unit. Each of the first pigment units 221 is formed by combining a plurality of first filter pigments 222 of different colors. Each of the first filter pigments 222 corresponds to the first photosite 211. When the first photosensitive point 221 senses the light passing through the first filtering pigment 222, the color information of the image pixel corresponding to the first photosensitive point 211 can be obtained. The central processing unit processes the sensing signal of each first photosite 211 in combination with the information of the plurality of first filter pigments 222 array, so as to obtain the multi-color distribution information of the image, and obtain the color of the image. Each of the first photosensitive points 211 corresponds to one of the first light filtering pigments 222, that is, the image pixel point corresponding to each of the first photosensitive points 211 can only obtain one color, and other color information of each image pixel point needs to be obtained by a central processing unit through an interpolation algorithm or other compensation algorithms, so that color distortion exists in the image obtained through the first photosensitive chip 21 and the first light filter 22. The image obtained by the second camera 30 and the image obtained by the third camera 40 need to be mutually compensated to obtain a more real-color image.

Each of the second color elements 321 is formed by combining a plurality of first filter colors 322 of different colors. The second filter 32 is provided with a plurality of second filter pigments 322 arranged in an array. Each of the second filter pigments 322 corresponds to each of the second photosites 311. When the second photosensitive point 311 senses the light passing through the second filtering pigment 322, the color information of the image pixel corresponding to the second photosensitive point 311 may be obtained. The color of light that can be transmitted by the second filter pigment 322 is different from the color of light that can be transmitted by the first filter pigment 222. The central processing unit processes the sensing signal of each second photosite 311 in combination with the arrangement information of the second filter pigments 342, so as to obtain the multi-color distribution information of the image, and obtain the multiple colors of the image. Each second photosensitive point 311 corresponds to one second light filtering pigment 322, that is, the image pixel point corresponding to each second photosensitive point 311 can only obtain one color, and other color information of each image pixel point needs to be obtained by the central processing unit through an interpolation algorithm or other compensation algorithms, so that the image obtained through the second photosensitive chip 31 and the second light filter 32 also has color distortion. Since the arrangement of the second filter pigment 322 is different from that of the first filter pigment 222, the color information of each image pixel acquired by the first camera 20 and the color information of each image pixel acquired by the second camera 30 can be added, so that each image pixel has two kinds of color information, the number of colors to be interpolated and compensated is reduced, the calculation cost is reduced, and the color fidelity of the image is improved.

Each of the third color element units 421 is formed by combining a plurality of third filter colors 422 of different colors. The third filter 42 is provided with a plurality of third filter pigments 422 arranged in an array. Each of the third filter pigments 422 corresponds to each of the third photosites 411. When the third photosite 411 senses the light passing through the third filter pigment 422, the color information of the image pixel corresponding to the third photosite 411 can be obtained. The color of light that can be transmitted by the third filter pigment 422 is different from the color of light that can be transmitted by the first filter pigment 222. The central processing unit processes the sensing signal of each third photosite 411 in combination with the arrangement information of the plurality of third filter pigments 422, so as to obtain the multi-color distribution information of the image, and obtain the multiple colors of the image. Each third photosite 411 corresponds to one third filter pigment 422, that is, the image pixel point corresponding to each third photosite 411 can only obtain one color, and other color information of each image pixel point needs to be obtained by a central processing unit through an interpolation algorithm or other compensation algorithms, so that the image obtained through the third photosite 41 and the second filter 42 has color distortion. Since the third filter pigment 422 has a different arrangement from the first filter pigment 222 and a different arrangement from the second filter pigment 322, the color information of each image pixel acquired by the first camera 20, the color information of each image pixel acquired by the second camera 30, and the color information of each image pixel acquired by the third camera 40 can be added, so that each image pixel has three kinds of color information, the number of colors to be interpolated and compensated is reduced, the calculation cost is reduced, and the color fidelity of the image is improved.

It can be understood that, referring to fig. 5, 6 and 7, the first color element unit 221 may be formed by three first filter color elements 222 with different colors, and each of the first color element units 221 is provided with two first color elements 223, a second color element 224 and a third color element 225. The first pigment 223 may be a green pigment. The second pigment 224 may be a red pigment, and the third pigment 225 may be a blue pigment. The two first color elements 223 are arranged diagonally, and the second color element 224 is arranged diagonally to the third color element 225. Of course, the first pigment unit 221 may be formed of four first filter pigments 222, and the four first filter pigments 222 may be a yellow pigment, a blue pigment, a green pigment, and a red pigment, or a cyan pigment, a green pigment, a red pigment, and a blue pigment, respectively. The first pigment unit 222 may be composed of five first filter pigments 222 of different colors, or may be composed of six first filter pigments 222 of different colors.

Each of the second color elements 321 is provided with a first color element 223, a second color element 224 and a third color element 225, and the first color element 223, the second color element 224 and the third color element 225 are sequentially arranged side by side. Since the position point of the first color filter 22 where the first color element 223 is arranged is partially different from the position point of the second color filter 32 where the first color element 223 is arranged, the position point of the first color filter 22 where the second color element 224 is arranged is partially different from the position point of the second color filter 32 where the second color element 224 is arranged, and the position point of the first color filter 22 where the third color element 225 is arranged is partially different from the position point of the second color filter 32 where the third color element 224 is arranged, the color information of each pixel point of the image acquired by the first camera 20 and the color information of each pixel point of the image acquired by the second camera 30 are superimposed, so that the color information of the first color element 223 and the color information of the second color element 224 can be obtained by a part of the pixel points where the target image exists, or the color information of the first color element 223 and the color information of the second color element 224 can be obtained by a part of the pixel points where the target, and the third color element 225, thereby reducing interpolation operations for the image of the first camera 20 and the image of the second camera 30 and improving color fidelity of the target image. Of course, in other embodiments, the colors of the three second filter pigments 322 of the second pigment unit 321 are all different from the colors of the three first filter pigments 222 of the first pigment unit 221. The second color element 321 may also be composed of four second filter pigments 322, and the four second filter pigments 322 may be orange pigment, cyan pigment, purple pigment and red pigment, or cyan pigment, gray pigment, red pigment and blue pigment.

The third color element unit 421 includes a first color element 223, a second color element 224, and two third color elements 225, where the two third color elements 225 are arranged diagonally, and the first color element 223 and the second color element 224 are arranged diagonally. Since the position point of the first color filter 22 where the first color element 223 is arranged is partially different from the position point of the third color filter 42 where the first color element 223 is arranged, the position point of the first color filter 22 where the second color element 224 is arranged is partially different from the position point of the third color filter 42 where the second color element 224 is arranged, and the position point of the first color filter 22 where the third color element 225 is arranged is partially different from the position point of the third color filter 42 where the third color element 224 is arranged, the color information of each pixel point of the image acquired by the first camera 20 is overlapped with the color information of each pixel point of the image acquired by the second camera 30 and is overlapped with the color information of each pixel point of the image acquired by the third camera 40, so that more pixel points of the target image can further obtain the color information of the first color element 223 and the color information of the second color element 224, or more pixel points exist to obtain the color information of the first pigment 223, the color information of the second pigment 224 and the color information of the third pigment 225, so that the interpolation operation of the image of the first camera 20, the image of the second camera 30 and the image of the third camera 40 is reduced, and the color fidelity of the target image is improved. Of course, in other embodiments, the colors of the three third filter pigments 422 of the third pigment unit 421 are all different from the colors of the three first filter pigments 222 of the first pigment unit 221. The third color element unit 421 may be formed of five third filter colors 422, and the five second filter colors 322 may be a brown color element, a green color element, a yellow color element, and a red color element, or may be a cyan color element, a yellow color element, a red color element, and a blue color element, respectively.

Further, referring to fig. 8, 9 and 10, the photographing device 100 further includes a fourth camera 50, and the fourth camera 50 includes a fourth photosensitive chip 51 fixed to the base 10 and a fourth optical filter 52 stacked on the fourth photosensitive chip 51. The fourth filter 52 transmits polychromatic light of the photographing light. The fourth photosensitive chip 51 collects a plurality of color distribution information of the polychromatic light. The fourth filter 52 includes a plurality of arrays of fourth color elements 521, and each of the fourth color elements 521 includes at least three different color elements arranged in a fourth array.

In the present embodiment, the fourth camera 50 is spaced apart from the first, second, and

third cameras

20, 30, and 40. The fourth photosensitive chip 51 is parallel to the third photosensitive chip 42. The fourth filter 52 is attached to the fourth photosensitive chip 51. The edge of the fourth filter 52 is substantially aligned with the edge of the fourth photosensitive chip 51. The fourth camera 50 has a smaller distance with the first camera 20, the second camera 30 and the third camera 40, so that image scenes shot by the first camera 20, the second camera 30, the third camera 40 and the fifth camera 50 are consistent.

The length and width of the fourth photosensitive chip 51 are the same as those of the first photosensitive chip 21. The fourth photosensitive chips 51 are arranged with the same number of fourth photosensitive sites 511 as the first photosensitive chips 21. The maximum size of the shot image acquired by the first photosensitive chip 21 is the same as the maximum size of the shot image acquired by the fourth photosensitive chip 1, so that the image acquired by the first photosensitive chip 21, the image acquired by the second photosensitive chip 32, the image acquired by the third photosensitive chip 42 and the image acquired by the fourth photosensitive chip 52 are convenient to perform.

Each of the fourth color elements 521 is formed by combining a plurality of fourth filter colors 522 of different colors. The fourth filter 52 is provided with a plurality of fourth filter pigments 522 arranged in an array. Each of the fourth filter pigments 522 corresponds to each of the fourth photosites 511. When the fourth photosite 511 senses the light passing through the fourth filtering pigment 522, the color information of the image pixel corresponding to the fourth photosite 511 can be obtained. The color of light that can be transmitted by the fourth filter pigment 522 is different from the color of light that can be transmitted by the first filter pigment 222. The central processing unit processes the sensing signal of each fourth photosite 511 in combination with the arrangement information of the plurality of fourth filter pigments 522, so as to obtain the multi-color distribution information of the image, and obtain the multiple colors of the image. Each fourth photosite 511 corresponds to one fourth light filtering pigment 522, that is, an image pixel point corresponding to each fourth photosite 511 can only obtain one color, and other color information of each image pixel point needs to be obtained by a central processing unit through an interpolation algorithm or other compensation algorithms, so that an image obtained through the fourth photosite 51 and the fourth light filter 52 also has color distortion. Since the arrangement of the fourth filter pigment 522 is different from the arrangement of the first filter pigment 222, the arrangement of the second filter pigment 322, and the arrangement of the third filter pigment 422, the color information of each image pixel acquired by the first camera 20, the color information of each image pixel acquired by the second camera 30, and the color information of each image pixel acquired by the third camera 40 may be added to the color information of each image pixel acquired by the fourth camera 50, so that each image pixel may have four color information, the number of colors to be interpolated and compensated is reduced, the calculation cost is reduced, and the color fidelity of the image is improved.

The fourth color element unit 521 is provided with a first color element 223, a second color element 224, a third color element 225, and a fourth color element 523 arranged in an array. The fourth pigment 523 may be a yellow pigment. Since the position point of the first color filter 22 where the first color element 223 is arranged is partially different from the position point of the fourth color filter 52 where the first color element 223 is arranged, the position point of the first color filter 22 where the second color element 224 is arranged is partially different from the position point of the fourth color filter 52 where the second color element 224 is arranged, the position point of the first color filter 22 where the third color element 225 is arranged is partially different from the position point of the fourth color filter 52 where the third color element 224 is arranged, and the fourth color filter 52 has a larger number of fourth color elements 523 than the first color filter 22, the second color filter 32 and the third color filter 42. Therefore, the color information of each pixel point of the image obtained by the first camera 20 is overlapped with the color information of each pixel point of the image obtained by the second camera 30, and is overlapped with the color information of each pixel point of the image obtained by the third camera 40, and is overlapped with the color information of each pixel point of the image obtained by the fourth camera 50, so that more pixel points of the target image can be further used for obtaining the color information of the first pigment 223 and the color information of the second pigment 224, or more pixel points can be used for obtaining the color information of the first pigment 223, the color information of the second pigment 224, the color information of the third pigment 225, and the color information of the fourth pigment 523, thereby reducing the color change of the image of the first camera 20, And the image interpolation operation of the second camera 30, the third camera 40 and the fourth camera 50 is carried out, and the color fidelity of the target image is improved. Of course, in other embodiments, the fourth color element 521 is composed of five fourth filter colors 522 of different colors.

Further, referring to fig. 11 and 12, the photographing device 100 further includes a fifth camera 60, where the fifth camera 60 includes a fifth photosensitive chip 61 fixed to the base 10, and the fifth photosensitive chip collects light brightness information.

In this embodiment, the distance between the fifth camera 60 and the first camera 20, the second camera 30, the third camera 40 and the fourth camera 50 is small, so that the image scenes shot by the first camera 20, the second camera 30, the third camera 40, the fourth camera 50 and the fifth camera 60 are consistent. The length and width dimensions of the fifth photosensitive chip 61 are the same as those of the first photosensitive chip 21. The fifth photosensitive chips 61 are arranged with the same number of fifth photosensitive points 611 as the first photosensitive chips 21. The maximum size of the photographed image acquired by the first photosensitive chip 21 is also the same as the maximum size of the photographed image acquired by the fifth photosensitive chip 62.
