Image sensor

An image sensor includes an array of image pixels and black level correction (BLC) pixels. Each BLC pixel includes a BLC pixel photodetector, a BLC pixel sensing circuit, and a BLC pixel optics assembly configured to block light that impinges onto the BLC pixel photodetector. Each BLC pixel optics a...

Zusammenfassung:	An image sensor includes an array of image pixels and black level correction (BLC) pixels. Each BLC pixel includes a BLC pixel photodetector, a BLC pixel sensing circuit, and a BLC pixel optics assembly configured to block light that impinges onto the BLC pixel photodetector. Each BLC pixel optics assembly may include a first portion of a layer stack including a vertically alternating sequence of first material layers having a first refractive index and second material layers having a second refractive index.
