1. A method for image scaling by area based interpolation, comprising the steps of:

  • deconvolving the data xmn by low resolution sensor function, where xmn is the output of a single sensor;

    upsampling to a desired resolution;

    convolving the up-sampled data by a high resolution sensor function; and

    low pass filtering to remove spectral aliases.
