Patent ID: 8179456

Claim:
An image sensor, comprising: a microlens; a color filter array; and a photo sensing unit; wherein the microlens is adapted to gather optical signals incident from a light source, wherein the color filter array is adapted to receive the optical signals that have passed through the microlens, wherein the color filter array is further adapted to transmit only optical signals within a frequency range, wherein the photo sensing unit is adapted to receive the optical signals from the color filter array in order to generate electrical signals depending on an intensity of the optical signals, wherein the color filter array comprises: two or more yellow filter pixels; one or more green filter pixels; and one or more cyan filter pixels; wherein the two or more yellow filter pixels are disposed consecutively in a first row or rows in a first direction, wherein the one or more green filter pixels and the one or more cyan filter pixels are disposed in a second row or rows in the first direction, wherein the first row or rows and the second row or rows alternate in a second direction perpendicular to the first direction, and wherein in the second direction, either the one or more green filter pixels and at least one of the two or more yellow filter pixels alternate or the one or more cyan filter pixels and at least one of the two or more yellow filter pixels alternate.
