For example, for some electronic devices, the camera module of the electronic device usually further comprises a polarizer, and the polarizer has a very obvious advantage in some scenes, such as shooting haze weather, shooting water surface environment, and the like. The image that uses the polarizer to obtain can effectively reject the interference of haze, and in the color aspect of picture, the color seems more saturated, and the leaf meadow is greener more gorgeous.

Referring to fig. 1, a schematic structural diagram of an image sensor according to an embodiment of the present application is shown, and as shown in fig. 1, the image sensor may specifically include: a substrate 10 and a plurality of color pixels 11 and white pixels 12 disposed on the substrate 10, the plurality of color pixels 11 and the plurality of white pixels 12 being alternately distributed; wherein, at least some white pixels 12 are provided with two polarizers 13 arranged at intervals, and the two polarizers 13 in the same white pixel 12 have the same deviation direction.

In the embodiment of the present application, the image sensor may include a substrate 10, and a plurality of color pixels 11 and a plurality of white pixels 12 disposed on the substrate 10, the plurality of color pixels 11 and the plurality of white pixels 12 being alternately distributed; at least some of the white pixels 12 are provided with two polarizers 13 disposed at intervals, and the two polarizers 13 in the same white pixel 12 have different polarization directions. In a specific application, the color pixels 11 can be used for sensitization to form a high-definition image, and the two polarizers 13 in the white pixels 12 can be used for polarization sensitization and phase focusing to form a polarized image. Thus, when the image sensor is used in an image pickup module, a polarized image can be formed by the polarizing plate 13 on the white pixel 12 without adding a polarizer, and a high-definition image can be obtained by the color pixel 11. That is, the image sensor can give consideration to both the polarization effect and the image definition, and obtain an image with higher quality.

Specifically, the substrate 10 may serve as a structural body of the image sensor for supporting the color pixels 11 and the white pixels 12. As shown in fig. 1, the color pixels 11 may include a red pixel (R), a blue pixel (B), a green-red pixel (Gr), a green-blue pixel (Gb), and the like, and the white pixels 12 (W) may be blank pixels.

Thus, when the image sensor is used in an image pickup module, a polarized image can be formed by the polarizing plate 13 on the white pixel 12 without adding a polarizer, and a high-definition image can be obtained by the color pixel 11. That is, the image sensor can give consideration to both the polarization effect and the image definition, and obtain an image with higher quality.

In a specific application, after the two polarizing plates 13 arranged at intervals are superposed on the white pixel 12, not only can a polarized image be formed by sensitization, but also a moving object in the direction of the camera Jiao Pianzhen can be realized

Optionally, the polarization directions of the polarizers 13 in the at least two white pixels 12 are different, and since the polarizers 13 only allow polarized light in the polarization directions to pass through, under the condition that the polarization directions of the polarizers 13 in the at least two white pixels 12 are different, at least two polarized lights in different polarization directions can be allowed to pass through to form polarized images in different polarization directions, and by fusing the polarized images in different polarization directions, a high-quality polarized image can be obtained, and the quality of an image obtained by the image sensor is improved.
