Abstract

Integral photography is one of excellent 3D display systems in which viewers can see 3D objects from arbitrary viewpoints without wearing special glasses. This system can be realized by sandwiching a transparent board between two transparent sheets, which are OHP sheets on which special still images were printed by an ink jet printer. The upper transparent sheet is a pinhole array, therefore even when its data compression is needed, it is very orderly and can easily be compressed. On the other hand, the image printed on the lower transparent sheet is complex and the resolution of the image is very high. For example, the number of picture elements is 5760 × 5760 and the depth is 3(RGB)×8 bit. Therefore, compression is strongly required. This paper describes lossless compression algorithms suitable for the image to be printed on the lower transparent sheet. Through experiments it has been shown that PNG is considerably better than GIF and JPEG2000.
