Abstract

The space distribution of photoreceptors is a main topic in artificial retina design procedures. A fundamental question is how different retina architectures reproduce the same image and which their properties are? This paper presents a new method to emulate the visual response of biological or artificial retinas. The proposed method can predict the vision output image of any retina with known photoreceptors distribution. A simple method is proposed that considers only two parameters to simulate the output image of any retina architecture: the distribution of the photoreceptors in the retina and the estimated light response of its photoreceptors. The distribution of the photoreceptors along the retina is modeled by geometrical figures that let define a set of many different outer trajectories. The paper discusses also a new method to organize the layout of any retinal architecture design using a set of basic square vertical phototransistors cells according with a previously defined photoreceptors distribution. The Lena image is used to predict the degree of resolution at the central area and how it is faded towards the periphery. © 2011 Elsevier B.V. All rights reserved.
