Abstract

The application discloses an image sensor, an imaging system and a terminal. The image sensor includes a metalens and a pixel array. The pixel array is located on the light-emitting side of the metalens. The metalens is used to split the incident light from the light-incident side of the metalens to form a variety of outgoing light with different wavelengths. The exiting light is projected from the light exiting side to the pixel array at different exiting angles. In the image sensor, imaging system and terminal according to the embodiments of the present application, the hyperlens divides the incident light from the light incident side into multiple outgoing light rays with different wavelengths, and the outgoing light rays of different wavelengths are sent to the pixel array at different outgoing angles. For imaging, the light is not filtered, there is almost no loss, and the light utilization rate is high.

Description

technical field [0001] The present application relates to the technical field of consumer electronics, in particular to an image sensor, an imaging system and a terminal. Background technique [0002] In related technologies, the image sensor generally splits the light through a color filter array (CFA), and divides the light into three colors of red, green and blue, and then enters the pixel array of the image sensor for photoelectric conversion to form an image. When the light passes through each CFA, only one color of light passes through, and the other light is filtered and lost, so the light utilization rate is low. Contents of the invention [0003] Embodiments of the present application provide an image sensor, an imaging system, and a terminal. [0004] An image sensor according to an embodiment of the present application includes a metalens and a pixel array. The pixel array is located on the light exit side of the hyperlens, and the hyperlens is used to split t...
