1. An imager, comprising:

  • a pixel array, includinga first floating diffusion region,a second floating diffusion region,a first source follower transistor having a gate coupled to the first floating diffusion region,a second source follower transistor having a gate coupled to the second floating diffusion region,a plurality of first pixels associated with a first color and configured to transfer charge to the first floating diffusion region,a plurality of second pixels associated with a second color different than the first color, configured to transfer charge to the first floating diffusion region, and arranged in a single column with the first pixelsa plurality of third pixels associated with a third color different than the first and second colors, anda plurality of fourth pixels associated with the first color, configured to transfer charge to the second floating diffusion region, and arranged in a single column with the third pixels; and

    control circuitry operably coupled to the pixel array, wherein the control circuity is configured to successively read out onto a column line image signals corresponding to the charge transferred to the first floating diffusion region via each of the first and second pixels.
