  • Publication number: 20240080577
    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.

  • Publication number: 20240079429
    Abstract: An image sensor includes a sensor substrate including a plurality of unit pixel groups each including a first pixel, a second pixel, a third pixel, and a fourth pixel arranged in a Bayer pattern, and a color separating lens array which separates incident light according to wavelengths and condenses the light on each of the first to fourth pixels, wherein the color separating lens array a plurality of pixel corresponding groups respectively corresponding to the plurality of unit pixel groups, and the plurality of pixel corresponding groups each include first to fourth pixel corresponding regions corresponding to the first to fourth pixels and a plurality of nanoposts. From among the plurality of pixel corresponding groups, relative positional relationships between the nanoposts of the first to fourth pixel corresponding regions in each of the plurality of peripheral groups that are located out of the center of the color separating lens array may be different from each other.
