A color filter array includes a plurality of white filters, a plurality of yellow filters, a plurality of cyan filters and a plurality of green filters. The plurality of white filters transmits incident light. The plurality of yellow filters transmits a green component and a red component of the incident light. The plurality of cyan filters transmits the green component and a blue component of the incident light. The plurality of green filters transmits the green component of the incident light. An image sensor including the color filter array has high sensitivity and high SNR by increasing transmittance of the incident light.

Color filter array, image sensor including the color filter array and system including the image sensor

An apparatus includes an array of color-selective sensors arranged as a plurality of repeating 2&#xd7;2 unit pixel groups. Each sensor of a unit pixel group of the array is selective for a color including a green component. The unit pixel group includes respective sensors selective for respective first and second colors and two sensors selective for a third color. Signals from the sensors of the unit pixel groups may define a first color signal space, and the apparatus may further include an image processor circuit configured to receive image sensor signals from the array of color-selective sensors and to process the image sensor signals to generate image signals in a second color signal space.
