Zusammenfassung:	PURPOSE: A unit image sensor for compensating for leaked light, an image sensor array made of the unit image sensor, and a method for compensating for leaked light of the image sensor array are provided to compensate for leaked light currents remaining a storage diode configuring a normal image sensor array. CONSTITUTION: A unit image sensor receives light(LIGHT) from a backside area(DEEP PD1,DEEP PD2). Charges generated in the backside area are transferred to the storage diode through several processes. A global shutter step transfers signals which are optically converted from all photo diodes into a floating diffusion area. An electrical signal corresponding to charges transferred to the floating diffusion area is outputted by a line unit.
