Abstract:
1. An areal active pixel image sensor (AAPS) with programmable row-specific gain for converting an incoming hyper-spectral light image into a corresponding video output signal (VOS), the AAPS comprises: a) an imaging array further comprising M-rows×N-columns (M>1, N>=1) of active pixel sensor (APS) elements APS b) a video output signal conditioner (VOSC), coupled to the imaging array, for multiplexing and amplifying said photoelectric signals PES c) said VOSC further programmably sets at least one of said GPE whereby the AAPS exhibits an overall photoelectric signal gain of GOA jk =GPE jk ×GEE jk that is row-specific hence capable of compensating for a problem caused by non-uniform spectral response of the APS elements during hyper-spectral imaging.
