In this paper, we proposed an efficient compression coding method for a digital hologram (fringe pattern) image/video. It uses a multi-view prediction (MVP) technique and a temporal motion prediction (TMP) technique to remove the spatial and temporal data redundancies, respectively. The predicted and compensated data is finally compressed by MPEG video compression standard techniques. Both MVP and TMP are performed by the unit of a predefined segment of a fringe pattern on the bases of its localization property. The experimental results with the implemented algorithm showed that the proposed method has NC (normal correlation) values about 4% higher than the previous methods at the same compression ratios, which convinced us that ours has better compression efficiency. Consequently, the proposed method is expected to be used effectively in the application areas to transmit or store in digital format the digital hologram data
