In this paper, we present a method to scale (that is, to enlarge or reduce) three-dimensional integral images of objects. The scaling is achieved by controlling the spatial ray sampling rate of elemental images in the pickup procedure of the object. The sampling is obtained by using a moving array-lenslet technique (MALT) during the recording stage. In the display process, a stationary display lenslet array is used. The lateral and longitudinal magnifications obtained with the proposed method are the same, therefore three-dimensional image distortion can be avoided. To illustrate the feasibility of our method, experiments are performed to magnify a small object in three-dimensional space.
