1. An apparatus for acquiring images, the apparatus comprising:
an image sensor comprising:
a sensor substrate comprising a plurality of first photo-sensing cells, a plurality of second photo-sensing cells, a plurality of third photo-sensing cells and a plurality of fourth photo-sensing cells configured to sense light; and
a color separation lens array provided above the sensor substrate, the color separation lens array comprising a fine structure in each of a plurality of regions respectively facing the plurality of first to fourth photo-sensing cells and configured to separate incident light in two-dimensional direction based on color, the fine structure forming a two-dimensional phase distribution to condense light having different wavelengths on corresponding photo-sensing cells, the fine structure comprising a plurality of nanoposts; and
a processor configured to perform, deconvolution on sensing signals of the plurality of photo-sensing cells to process an image signal for each color obtained by the image sensor and configured to form a color image from the image signal.
