This paper provides an overview of a method for a compression of elemental images in the photon counting three-dimensional (3D) integral imaging. Experimental results show that a considerable compression of the elemental images in 3D integral imaging can be achievable without significant loss in the correlation performance and 2-bit photon counting quantization is enough to reconstruct an original 3D scene when the pixel resolution of the elemental image with 8-bit gray codes is 256×128. It is also shown that the data size of elemental image set can be reduced by about 99.88% with a good correlation coefficient value (>0.50) compared with that of the case of no compression.
