Abstract

An image sensor is disclosed. The image sensor may include pixel groups, which are two-dimensionally arranged on a substrate, and each of the pixel groups including a plurality of pixels. The image sensor may also include a light-blocking pattern, which is disposed on the substrate and between the pixels. The pixel groups may include first image pixel groups sensing a first light, second image pixel groups sensing a second light, and an auto-focus (AF) pixel group detecting a phase. The AF pixel group may include a first AF pixel and a second AF pixel adjacent to each other, and the light-blocking pattern may be absent on the substrate between the first AF pixel and the second AF pixel.

An image sensor, comprising:

pixel groups two-dimensionally arranged on a substrate, each of the pixel groups including a plurality of pixels;
and
a light-blocking pattern on the substrate and between pixels among the plurality of pixels,
wherein the pixel groups comprise:
first image pixel groups configured to sense a first light;
second image pixel groups configured to sense a second light;
and
