Patent Images

1. A method of image processing comprising:

  • capturing a first captured image with at least a first image sensor, the first captured image including a first frame of initial pixel data captured by a first plurality of camera pixels;

    assigning a color mosaic of color information to the initial pixel data to generate alternating single-color pixel data of known color information for each of the first plurality of camera pixels to form at least two color channels;

    with a processor, estimating missing color information for each of the first plurality of camera pixels in the first frame;

    for each array of a plurality of arrays of camera pixels in the first frame, generating correlation information to determine if a pair of the at least two color channels are substantially correlated in response to the known color information and the estimated color information; and

    if a pair of color channels are substantially correlated within an array thendemosaicing each camera pixel in the array in response to its single-color pixel data and the correlation information to generate full color pixel data for each camera pixel within the array and form a portion of a first full color image of the first captured image.
