Demosaicing for a colour filter array

摘要

Provided are a method and apparatus to restore an image with a high resolution from an image obtained through a miniaturized camera module. The method includes obtaining a plurality of original color-separated images through a camera module including a plurality of lenses and a plurality of image sensing areas corresponding to the lenses, respectively, generating a first intermediate image corresponding to the sensing areas, the first intermediate image being divided into a plurality of pixel groups, generating a second intermediate image by mapping pixel information of pixels at identical positions in respective original color-separated images onto a predetermined pixel of a pixel group in the first intermediate image corresponding to the identical position, and generating a final image by interpolating the second intermediate image. The pixel group includes a plurality of pixels corresponding to an arrangement pattern of color filters.
