Abstract	In this paper, we introduce and propose a new Digital Zoom method based on the HCI color model which is a new color representation scheme. The HCI color model consists of three channels; hue, chroma, and intensity. Since this new color model is not expanded to a cylindrical form, not only the problem of saturation dependence on the brightness can be avoided, but also the fully saturated achromatic color problem cannot occur. When interpolation for the Digital Zoom is performed by the existing interpolation methods, it appears typical problems about mosaic or jaggies. Our purpose is to minimize the problems about mosaic or jaggies. We adopted the HCI color model for robust against illumination effects. Also, we applied the Flood Fill Mean Shift and the B-Spline Snake algorithm for improving the Digital Zoom.
