Abstract
A circuit system for estimating position and orientation of a mobile object based on lights from a plurality of external light sources. The circuit comprises a position-sensitive light sensor for detecting the light sources and generating a first signal, an analog filter and amplification module ('AFA') for filtering and amplifying the first signal and generating a second signal, a digital signal processor ('DSP') for generating a coordinate system by extracting frequency components from the second signal.
