Abstract

The present invention relates to an image sensor. The image sensor comprises a pixel array, and the pixel array comprises a first pixel unit and a second pixel unit which are alternately distributed.The first pixel unit comprises: a first radiation sensing element configured to sense radiation of a first wavelength range; and a second radiation sensing element configured to sense the radiation ofa second wavelength range different from the first wavelength range, wherein the first radiation sensing element is separated from the second radiation sensing element. The second pixel unit comprises: a third radiation sensing element configured to sense radiation of a third wavelength range, wherein the third wavelength range is different from the first wavelength range and the second wavelength range; and a fourth radiation sensing element configured to sense the radiation of the second wavelength range, wherein the third radiation sensing element is separated from the fourth radiation sensing element.

Description

technical field [0001] The present disclosure relates to a pixel unit, an image sensor, a method of manufacturing the same, and an imaging device. Background technique [0002] Image sensors may be used to sense radiation (eg, optical radiation, including but not limited to visible light, infrared, ultraviolet, etc.) to generate corresponding electrical signals (eg, images). It is widely used in digital cameras, mobile communication terminals, security facilities and other imaging devices. [0003] Currently, image sensors generally use a Bayer-patterned pixel array. In the Bayer mode, each pixel only senses the radiation of one primary color, and the radiation values ​​of the other two primary colors of the pixel are obtained by interpolation calculation using the radiation values ​​of surrounding pixels. Consequently, the resulting image loses some image detail and causes color aliasing. [0004] Therefore, it is necessary to propose a new technology to solve one or mor...
