<p>PROBLEM TO BE SOLVED: To provide an optical instrument capable of treating a light field photography so as to achieve at least one of enhancement of image resolution and increase in the amount of beam incident direction information.SOLUTION: An optical instrument used for a light field photography, includes: a micro lens array 103 disposed in a position conjugate with a photogenic subject 101 for widening a beam from the photogenic subject; an image pick-up device 104 for photo-electrically converting the beam having passed through the micro lens array; a micro lens array move part 109 for moving the micro lens array in a direction perpendicular to an optical axis; and a micro computer 107 for allowing the image pick-up device to capture an image to produce beam data when the micro lens arrays is placed in at least two different places by the micro lens array move part.</p> |
