Abstract
An image sensor includes a pixel array in which a plurality of normal pixels and a plurality of autofocus (AF) pixels are disposed, and a logic circuit. The logic circuit provides an autofocus function using a phase difference between pixel signals obtained from each of the plurality of AF pixels. Each of the AF pixels includes a single AF lens disposed on a pair of pixel areas. An AF lens of the AF pixel spaced apart from a center of the pixel array may have an area larger than an area of the AF lens of the AF pixel adjacent to the center.
