Abstract

The goal of this paper is to simulate the conversion from light to numerical signal which occurs during the image propagations through the digital camera pipeline. We focus on the spectral and resolution analysis of the optical system, the Bayer sampling, the photon shot and fixed pattern noise, the high dynamic range image, the amplitude and bilateral filters and the analog to digital conversion. The image capture system consists of a flash illumination source, a Cooke triplet photographic objective and a passive pixel CMOS sensor. We use a spectral image in order to simulate the illumination and the propagation of the light through the optical system components. The Fourier optics is used to compute the point spread function specific to each optical component. We consider the image acquisition system to be linear shift invariant and axial. The light propagation is orthogonal to the system.
