The optical comlnllnication system based on LED traf 旦c lights or LED head / tail lights is pleselltly being studied for thc realization of the advaI ⊥ced traf 登c systen1 . For this purpose , deviccs for finding the area of signal light s urces and receiving the optical communication signals are necessary 、 This paper presen 七 s a CMOS Image Sellsor for car − to − car and road −to − car optical comrnunications .
