Abstract
This application discloses an image sensor, which includes a color film layer. The color film layer includes a plurality of color film units, the color film unit includes at least one color-determined subunit and at least three transparent subunits, and a color of the color-determined subunit is determined. The color-determined subunit is configured to filter out a portion of the received light, and the transparent subunit is configured to allow light to pass through. A ratio of a quantity of the at least one color-determined subunit to a quantity of the plurality of subunits is less than 1/2. Because the transparent subunit can allow light to pass through, and most of light incident to the color film layer can be received by a photodiode, light sensitivity of the image sensor can be effectively increased without increasing an area of the color film layer or increasing a size of the photodiode.
