Classification: CPC H | IPC H

Claim 0:
1. An apparatus for sensing an image, said apparatus comprising:
a complementary metal oxide semiconductor (CMOS) sensor comprising an array of pixels with an intensity-based readout; and
an analog network including at least one carrier generator operably coupled to said array of pixels,, wherein each pixel in said array of pixels is fed with a carrier signal and wherein, for said each pixel, said carrier signal is modulated with a value representing an exposure of said each pixel,, and wherein said pixels output a current, IPixel, in the form of

IPixel=APhotodiode*sinCarrier(2πft+τ)+IOffset,, where f is the frequency of the carrier, τ is the phase of the carrier, IOffset is a DC offset current, and t is time.
