Effects of image compression on digital specklegrams are studied in order to solve storage problem of the speckle photography. By measuring a sharpness of correlation peak computed from the compressed specklegram, information quality of the specklegram is studied. The preliminary study shows that the specklegram could be compressed about 12 times smaller without distorting its information content.
