Abstract
In some implementations, a pixel array may include a near infrared (NIR) cut filter layer for visible light pixel sensors of the pixel array. The NIR cut filter layer is included in the pixel array to absorb or reflect NIR light for the visible light pixel sensors to reduce the amount of MR light absorbed by the visible light pixel sensors. This increases the accuracy of the color information provided by the visible light pixel sensors, which can be used to produce more accurate images. In some implementations, the visible light pixel sensors and/or MR pixel sensors may include high absorption regions to adjust the orientation of the angle of refraction for the visible light pixel sensors and/or the MR pixel sensors, which may increase the quantum efficiency of the visible light pixel sensors and/or the MR pixel sensors.
