1. An image sensor, comprising:
a color film layer, comprising a plurality of color film units, each color film unit comprising four subunits having at least one color-determined subunit and at least three transparent subunits, wherein when a color of a color-determined subunit is determined, the color-determined subunit is configured to filter out a portion of received light, wherein a transparent subunit is configured to allow light to pass through to be received by a photodiode, to increase a light sensitivity of the image sensor; and
wherein a ratio of a quantity of the at least one color-determined subunit to a total quantity of subunits in the color film unit is less than 1/2,
wherein a minimum combination unit comprises four color film unit arranged in a matrix form and four color-determined subunits of the four color film unit are distributed around a center of the minimum combination unit.
