1. An apparatus with image processing, the apparatus comprising:
one or more processors configured to:
generate a full sampling image by demosaicing a first color filter array (CFA)-based input image;
based on a trained color conversion model trained for color conversion and noise suppression of the full sampling image, determine a bias and a conversion matrix corresponding to each pixel of the full sampling image; and
based on the conversion matrix and the bias, convert a color space of the full sample image, corresponding to the first CFA, into a color space corresponding to a second CFA.
