Abstract
A method of fractally interpolating intensity values for a color component array derived from a single chip charge-coupled-device (CCD) is disclosed. The method includes selection of a domain area about an array element not having a value for the color component array. A plurality of range areas are selected which are larger than the domain area. Additional range areas may be generated by range area transformations and intensity value scaling and shifting. A difference measurement between each domain area and range area is determined and the range area corresponding to the smallest distance measurement is selected. The intensity values of the selected range area are then used to generate an interpolated intensity value for the domain area.
