The invention discloses an image sensor, a camera module and a terminal. The image sensor includes a pixel layer, a polarizing layer, and a filter layer. The pixel layer comprises a plurality of pixelgroups, and each pixel group comprises nine pixel units. The polarization layer comprises a plurality of polarization element groups, each polarization element group comprises nine polarization elements, each polarization element is provided with a plurality of polarization microstructures, the distance between every two adjacent polarization microstructures is larger than or equal to 50 nm, theangles of polarization axes of the nine polarization elements are different, and the polarization elements and the pixel units are in one-to-one correspondence. The light filtering layer comprises a plurality of light filters, the light filters, the polarization element groups and the pixel groups are in one-to-one correspondence, and the pixel units can receive polarized light penetrating throughthe corresponding light filters and the polarization elements. The image sensor, the camera module and the terminal generate different color polarization images according to the polarized light withcolor information and nine kinds of polarization angle information, and the scene utilization range is wide. The distance between the adjacent polarization microstructures is greater than or equal to50nm, so that the interference between the adjacent polarization microstructures can be avoided.
Description
technical field [0001] The present application relates to the technical field of consumer electronics, in particular to an image sensor, a camera module and a terminal. Background technique [0002] The current image sensor cannot distinguish the polarized light of different polarization angles in the scene being photographed, and cannot generate different color polarized images according to the polarized light of different polarization angles. Polarized light at a certain polarization angle generates color polarized images, etc., and the scope of use in the scene is small.
