Abstract: An image sensor includes a pixel array including a plurality of normal pixels, a plurality of phase detection groups, and a color filter array. Each phase detection group includes a first phase detection pixel and a second phase detection pixel disposed adjacent to the first phase detection pixel. The color filter array includes a plurality of unit groups. Each unit group includes a plurality of color filters of a same color arranged in an M×N matrix on the pixel array, wherein M and N are natural numbers. A first color filter among the color filters of a first color is disposed on the first phase detection pixel of one of the unit groups and a second color filter among the color filters of a second color different from the first color is disposed on the second phase detection pixel of another one of the unit groups.

Abstract: An electronic device includes a lens part that receives light from a subject, an image sensor that receives the light of the lens part from a group of pixels arranged two-dimensionally, and an processor that processes an image signal of the image sensor. The image sensor performs a read-out operation at a speed to prevent blurring of an image. The processor temporarily stores image data by the read-out operation in a memory, loads a plurality of images stored in the memory to generate an image, of which the number of bits is expanded compared with the image signal of the image sensor, and performs gamma processing on the image, of which the number of bits is expanded, to generate an image compressed to the same number of bits as the image signal of the image sensor.
