INTERLEAVED MOSAIC IMAGING RAIN SENSOR

摘要

A plurality of the first L1 and second L2 image sensor elements are interleaved with one another. The first image sensor elements L1 has a peak response at the first wavelength lambd1 for capturing an illuminated image of the glass and objects on the glass containing a first wavelength lambd1 from an infrared illuminator (12). The second image sensor element L2 has a peak response at a second wavelength lambd2 for capturing an ambient image of light rays at the second wavelength lambd2 passing through the glass (10) from the exterior to the interior surfaces simultaneously with the capture by the first image sensor element L1. Instead of storing two complete sequential images and differentially subtracting them, the present invention creates two simultaneous images from a specially interleaved, single imager (14).
