Classification: CPC H | IPC H

Claim 10:
11. A method for sensing an image, said method comprising:
providing a complementary metal oxide semiconductor (CMOS) sensor comprising an array of pixels having an intensity-based readout; and
coupling said array with an analog network comprising at least one carrier generator,, 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.
