Classification: CPC G | IPC G

Claim 14:
15. A method of acquiring images, the method comprising:
obtaining a raw image for each color by the image sensor, the image sensor comprising:
a sensor substrate comprising a plurality of 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 photo-sensing cells and configured to separate incident light based on color, the fine structure forming a phase distribution to condense light having different wavelengths on corresponding photo-sensing cells, the fine structure comprising a plurality of nanoposts;

performing, by a processor, deconvolution on the raw image for each color by using a point spread function (PSF) corresponding to each color pixel by the color separation lens array of the image sensor to thereby obtain an image for each color; and
processing, by the processor, the image for each color to thereby form the color image.
