    Abstract: An image acquisition apparatus according to an example embodiment includes an image sensor including a sensor substrate including a plurality of photo-sensing cells for sensing light thereon, and a color separation lens array disposed in front of the sensor substrate and including a nanostructure to separate incident light by color, wherein the nanostructure forms a phase distribution in a plurality of regions facing the plurality of photo-sensing cells, respectively, and the phase distribution is formed so as to condense light of different wavelengths onto photo-sensing cells adjacent to each other, and a processor configured to process an image signal for each color obtained from the image sensor. The processor is further configured to perform decoupling with respect to sensing signals of the plurality of photo-sensing cells by using a kernel defined from a point spread function determined by the phase distribution.

    Abstract: An image sensor may include a pixel array including a plurality of two-dimensionally arranged pixels. Each pixel may include a first meta-photodiode absorbing light of a first wavelength band; a second meta-photodiode absorbing light in a second wavelength band; and a third meta-photodiode absorbing light of a third wavelength band, wherein the first meta-photodiode, the second meta-photodiode, and the third meta-photodiode may be arranged in an area having a size less than a diffraction limit. The arrangement form of the first meta-photodiode, the second meta-photodiode, and the third meta-photodiode arranged in the plurality of pixels in a central portion of the pixel array may be the same as the arrangement form of the first meta-photodiode, the second meta-photodiode, and the third meta-photodiode arranged in the plurality of pixels in a periphery of the pixel array.
