## Abstract

A method for displaying three-dimensional integral images using a mask and a time division multiplexing which is configured in such a way that a three-dimensional image is displaced in a space as an element image obtained from a three-dimensional object is passed through a lenslet and a mask, the mask consisting of a blocking region through which an element image does not pass and a transmission region through which an element image passes, for thereby displaying three-dimensional images. The present invention is advantageous to play back a three-dimensional image the resolutions of which are enhanced in a depth-based integral imaging method using a time division display of an element image and a masked image.

## Claims

### Claim 1

A method for displaying three-dimensional integral images using a mask and a time division multiplexing; comprising:
allowing element images 130 and 230 obtained from a three-dimensional object 110 to pass through a lenslet 220 and a mask 240 for thereby displaying a three-dimensional image 210 in a space, the mask 240 being formed of a blocking region 242 through which the element image 230 does not pass, and a transmission region 241 through which the element image 230 passes for thereby displaying a three-dimensional image.

### Claim 2 (depends on 1)

The method of claim 1, wherein the mask 240 is configured in such a way that the positions of the blocking region 242 and the transmission region 241 alternate in sequence over time for thereby displaying a three-dimensional image.
