Abstract
A CMOS image sensor capable of auto focus control includes a sensing unit having a plurality of unit pixels for receiving an optical image of an external subject and outputting an electrical color signal of a corresponding pixel for each unit pixel, a control unit converting the electrical color signal from the sensing unit into a digital signal, processing the digital signal to output an image signal, and controlling the sensing unit, an auto focus (AF) algorithm unit receiving the image signal and calculating a focus value using an AF tracking algorithm, and an actuator control unit controlling an actuator using the focus value.
