DIGITAL RANGE IMAGING VLSI SENSOR

Abstract

In this paper, we present a digital scheme for fast VLSI range imaging sensor, which is a modification of the analog scheme of existing sensor implemented by T. Kanade [5]. Instead of reading timing information in analog manner, we use a digital scheme which has several advantages over the analog scheme, including area saving, insusceptibility to noise and other undesirable effects. We have implemented a prototype to test feasibility and present its experimental result.
