Abstract
An apparatus includes an array of color-selective sensors arranged as a plurality of repeating 2×2 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.
