Abstract

A system and method are used to carry out an adaptive image transformation to an original image plane to acquire a regenerated color image. The original image plane contains a configuration of a plurality of pixels to form an array, in which at least a interested pixel is contained therein. To regenerate the color image, the adaptive image transformation includes steps of interpolating color values of pixels adjacent to the interested pixel to obtain an additional color value; estimating a color value gradient of the interested pixel in two image directions; determining a weighting values along the two image directions in accordance with a lookup table; and further interpolating color values of those neighboring pixels by those weighting value to obtain the additional color value. A lookup table provides adjustable weighting values in accordance with the relation between color value gradients in the two image directions, thus achieves adaptation of maximum flexibility by using the interpolation.
