Beam split extended dynamic range image capture system

摘要

PROBLEM TO BE SOLVED: To provide an optical system related to acquisition of an extended dynamic range image. An optical system can include a lens element configured to receive incident light and a beam splitter optically coupled to the lens element. The beam splitter is configured to split the incident light into at least a first portion having a first photon bundle and a second portion having a second photon bundle. The first photon bundle is at least an order of magnitude more than the second photon bundle. The controller causes the first image sensor to capture the first image of the first portion of the incident light according to the first exposure parameter, and causes the second image sensor to capture the second image of the incident light according to the second exposure parameter. It may be configured to capture a second image of the portion of. [Selection diagram] Fig. 1
