Abstract

An image sensor includes a color filter array, a first photoelectric conversion device configured to absorb first light passing through the color filter array and convert the absorbed first light into electrical signals, and a second photoelectric conversion device configured to absorb second light passing through both the color filter array and the first photoelectric conversion device and convert the absorbed second light into electrical signals. The first photoelectric conversion device includes a first photoelectric conversion layer configured to selectively absorb a mixed light of the first and second colors. The second photoelectric conversion device comprises a second photoelectric conversion layer configured to absorb light including a third color. Each of the first to third colors is one of three primary colors. The image sensor combines the electrical signals converted from the first and second photoelectric conversion devices to obtain electrical signals of the first to third colors.
