A method for reading out pixel values from an image sensor, the method includes obtaining an array of pixels alternating a first color row pattern and a second color row pattern; transferring the pixel values to a vertical charge-coupled device; summing at least two rows of the first color row pattern in a horizontal CCD and dumping at least one row of the second color row pattern; reading out the summed first color row pattern from the horizontal CCD; summing at least two rows of the second color row pattern in the horizontal CCD and dumping at least one row of the first color row pattern; reading out the summed second color row pattern from the horizontal CCD; and dumping two consecutive rows.
