Abstract: A pixel array is provided. The pixel array includes: a plurality of pixels in a matrix, the plurality of pixels including a first pixel, a second pixel and a third pixel adjacent the second pixel; a plurality of micro lenses, the plurality of micro lenses including a first micro lens and a second micro lens. Each of the plurality of pixels includes a plurality of photoelectric conversion elements adjacent to each other in a first direction. The first micro lens extends across the plurality of photoelectric conversion elements of the first pixel, and the second micro lens extends in the first direction or a second direction across the second pixel and the third pixel.

Abstract: An image sensor includes a pixel array including a plurality of pixels arranged in a row direction and a column direction and a read-out circuit that generates image data and phase data based on a sensing signal received from the pixel array. The image sensor is configured the resolution of the phase data output by read-out circuit depending on target area information for the pixel array, the target area information received from outside of the image sensor.
