Abstract: A demosaicing method for an input mosaic image includes: obtaining an input image, for each sub target pixel, estimating a main edge direction based on main color pixel values; determining the main edge direction by performing edge enhancement based on the input mosaic image; generating a main color demosaiced image by performing a main interpolation based on the main edge direction to generate interpolated main color pixel values corresponding to the sub target pixels; and generating a first sub color demosaiced image and a second sub color demosaiced image by performing a sub interpolation to generate interpolated first sub color pixel values and interpolated second sub color pixel values for the sub target pixels and for main target pixels corresponding to the main color pixel values.
