Abstract
An interpolation method for producing full color images is disclosed. For a blue pixel, an interpolated green value is determined by green values of adjacent green pixels, and an interpolated red value is determined by red values of neighboring red pixels and a modification value. For a red pixel, an interpolated green value is determined by green values of adjacent green pixels, and an interpolated blue value is determined by blue values of neighboring blue pixels and a modification value. For a green pixel, an interpolated green value is determined by original green value of the green pixel and green values of neighboring green pixels, an interpolated red value is determined by red value of at least an adjacent red pixel and a modification value, and an interpolated blue value is determined by blue value of at least an adjacent blue pixel and a modification value.
