Patent Images

1. A digital image capturing apparatus, comprising:

  • an image pickup unit obtaining light field data to change a view of a captured image and refocus the captured image; and

    a data processor generating a refocusing image using the light field data,wherein the image pickup unit performs optical modulation on light beams to obtain light field data of the modulated light beams so that the light beams are individually identified when two or more of the light beams overlap, and the data processor demodulates the light field data to obtain demodulated light field data of the light beams not subjected to the optical modulation.
