APPARATUS AND METHOD FOR ACQUIRING INFORMATION ABOUT LIGHT-FIELD DATA
First Claim
1. An apparatus to acquire information about light-field data comprising:
- a beam splitter configured to split light, through a lens unit which is connected to the apparatus, from an object into a first light beam and a second light beam;
an image sensor configured to detect the first light beam to form an image of the object; and
a light-field sensor, including a lenslet array and a detecting unit to detect the second light beam through the lenslet array, configured to acquire information about the light-field data, the lenslet array including a plurality of lenslets,wherein a first position where the detecting unit is provided is conjugate to a second position of a pupil of the lens unit.

24. A method to acquire information about light-field data comprising:
-
splitting object light, passing through a lens, unit, into a first light beam and a second light beam; detecting the first light beam to capture an image of the object; inputting the second light beam into a lenslet array including a plurality of lenslets; scanning a spatial light modulator associated with each lenslet of the lenslet array, wherein the spatial light modulator is moved according to a zooming operation of the lens unit so that a conjugate relationship between a position of a pupil of the lens unit and a position of the spatial light modulator is maintained; and detecting the second light beam coming through the spatial light modulator to acquire information about light-field data of the object.
