1. A method of creating a super-resolved color image from a plurality of lower-resolution color images, the method comprising:

  • a. enforcing by a computer similarities between raw data and a high-resolution image estimate, wherein said enforcing uses a data fidelity penalty term, wherein said data fidelity penalty term is an L1 norm penalty term;

    b. encouraging by a computer sharp edges in a luminance component to said high-resolution image, wherein said encouraging uses a spatial luminance penalty term;

    c. encouraging by a computer smoothness in a chrominance component of said high-resolution image, wherein said encouraging uses a spatial chrominance penalty term;

    d. encouraging by a computer homogeneity of an edge location and orientation in different color bands, wherein said encouraging uses an inter-color dependencies penalty term; and

    e. a super-resolved color image is displayed on an computer monitor.
