Abstract:
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; 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; and an actuator configured to move the detecting unit in order to maintain a conjugate relationship between the first and the second positions when the pupil of the lens unit is moved according to a zooming operation of the lens unit.
