This paper present our color constancy investigation in the hybridization ofWireless LAN and Camera positioning in the mobile phone. Five typical colorconstancy schemes are analyzed in different location environment. The resultscan be used to combine with RF signals from Wireless LAN positioning by usingmodel fitting approach in order to establish absolute positioning output. Thereis no conventional searching algorithm required, thus it is expected to reducethe complexity of computation. Finally we present our preliminary results toillustrate the indoor positioning algorithm performance evaluation for anindoor environment set-up.
