AB  - We describe the relations between the statistics of the speckled image I(x) that 
      is produced by an astronomical object at the focus of a telescope and the 
      statistics of the point-source speckle pattern S(x) that is obtained under 
      comparable conditions of turbulence. We show that the characteristic function 
      (CF) of I(x) can be written as a central slice of a higher-order CF of S(x); as a 
      consequence, probability density functions (PDF's) of I(x) and S(x) are related 
      to one another by means of projections. An illustration, consisting of 
      one-dimensional scans obtained with the European Southern Observatory's 
      slit-scanning infrared specklograph, is made for real data. It is shown how the 
      onefold and twofold PDF's of a double star can be synthesized from the twofold 
      and the threefold PDF's of the reference source.
