Image sensor including a plurality of pixels and at least one lens

An image sensor comprising:

• a first pixel group comprising a first pixel, a second pixel, a third pixel and a fourth pixel arranged in a 2×2 matrix;
• a second pixel group comprising a fifth pixel, a sixth pixel, a seventh pixel and an eighth pixel arranged in a 2×2 matrix, wherein the second pixel group is provided adjacent to the first pixel in a first direction;
• a first floating diffusion node provided in a location corresponding to a center of the first pixel group, wherein the first floating diffusion node is connected to the first pixel, the second pixel, the third pixel and the fourth pixel;
• a first lens corresponding to the first pixel and the second pixel;
• a second lens corresponding to the third pixel and the fourth pixel;
• a device isolation pattern electrically isolating the first pixel group from the second pixel group;
• and
• a readout circuit configured to:
• output phase data based on at least a portion of phase signals received from the first pixel group;
• and
• output image data based on at least a portion of color signals received from the second pixel group,
• wherein the device isolation pattern comprises a plurality of portions which electrically separate the first pixel, the second pixel, the third pixel, and the fourth pixel from each other, and
• wherein each of the plurality of portions is spaced apart from the center of the first pixel group.
